Modules & VBA :: How To Change Controlsource Of Multiple Textboxes With Public Function
Jun 11, 2013
I have multiple reports that use similar IIF statements as the controlsource for four textboxes. Naturally, I don't want to have to update twelve controlsources if any of the calculations change, so I thought I'd make this a public function. However, I don't know how to pass along multiple textboxes as variables. Here's what I have so far:
Code:
Option Compare Database
Public Function txtColor(ByRef textbox As Control)
Dim str1, str2, str3, str4 As String
'The IIf statement is simplified for this example. It's not important.
str1 = "=IIf(IsNull([Inquiry start date]),'W',IIf([txtInquiry]<1 And IsNull([Inquiry end date]),'R'))"
[Code] ....
And this is in the report (where ??? is what I'm asking about)
Code:
Private Sub Report_Load()
Call txtColor(???)
End Sub
I am trying to read the value of a control on an open form from a Public Function in a Module with no luck. I suspect the issue is syntax.
Code:
Public Function MyFunction(varFormName As String, varControlName As String) If Forms(varFormName).Controls(varControlName) = True Then ' = 0 even when control is -1 Else End If End Function
The variables pass through fine but the If statement equals zero regardless of the state of the form's control. I tried several variations to no avail.
If Forms(varFormName).Form.Controls(varContactControl ) = True Then If Forms(varFormName)!Form.Controls(varContactControl ) = True Then Etc.
I have an issue with this case select below. The DelayStart is time so lets say I put in the debug window
?DatePart("h", #04:00pm#)
The result would be 16 which is correct BUT the issue is my second shift starts at 04:01pm and the result is still 16 untill 5pm. How do I fix this so I get the correct shifts? Im guesing use something other than DatePart but what?
Code: Public Function getShiftForRecord(DelayStart As Variant) On Error Resume Next Select Case DatePart("h", DelayStart) Case 6 To 16 'Daylight 6:00am - 4:00pm
I have built an access application that contains a set of buttons along the top of every form that serve as navigation.* These buttons each perform the same function on every form they are on. (menu opens the main menu, etc) I have database macros to assign each button the same function but I still have to go through each form and manually assign them. I was wondering if it was possible to define a public function that on db open will look for all buttons with a certain name and assign them the macro. (so all buttons called cmdmainmenu will have the OpenMainMenu macro assigned and so on).Before you go there, I have already tried the navigation form and set all forms as subforms.
Question for Documentation purpose: Should the Public Type be declared in its own module?
Or should it be declared in a standard module where non-public functions use it? It is not for a Form module use.
For a Rule Engine, a function is calling one record on 4 different SQL Views (as linked tables) that have the same field format.
For speed, the recordset should only be opened once. However, there are multiple values that must be returned to the result table multiple fields.
One way to return multiple values is an Array. That has over head too.
Another way is to create multiple public variables. Not my choice for documentation. Another is to create a string.
This is a pure code module with several non public functions / subs. What is the documentation preference? List a Public Type close to the function, or place it in the Global module?
Background: A function can only have one return value.
By creating a public Type, multiple values can be returned.
Code: Public Type Income Wages As Currency Dividends As Currency Other As Currency Total As Currency End Type
Use this structure as the return type for a function. In a real situation, the function would look up your database tables to get the values, but the return values would be assigned like this:
Code: Function GetIncome() As Income GetIncome.Wages = 950 GetIncome.Dividends = 570 GetIncome.Other = 52 GetIncome.Total = GetIncome.Wages + GetIncome.Dividends + GetIncome.Other End Function
To use the function, you could type into the Immediate Window:
GetIncome().Wages
(Note: the use of "Public" in the Type declaration gives it sufficient scope.)
Important Notice The way this function is called will work, but is wrong from the aspect it re-calls the recordset over and over.
I want this function to populate value from a any field selected from any table to any text box in any form ...... Lets say in a Database named TestDB we have a Table named tblTest , a Form named frmTest and in this form( frmTest ) we have one Bound Combo Box named cmbTest and one unbound TextBox named txtTest
We assume that the table tblTest has three fields : TestID , FName and LName .
We also assume that there are already some records in the Table tblTest .
If the function F() is already programmed it should take as arguments as it follows :
F(FormName as??? ,ControlName as ???, TableName as ???, FieldName as ???, ID_Field_Name_of_the_Table as ???, Combo_box_selected_ID as ???)
In result the function should (probably) DLookup (FieldName , TableName , ID_Field_Name_of_the_Table = Combo_box_selected_ID ) and then store the value in a variable ( probably Variant ???) , lets say called varSetValue.
The problem is IF this is the correct way to handle that issue , than what should i do next.... I really don't know how to pass a Control's name to a function from the Event module of the ComboBox -
I mean - how can I obtain the value so it is usable for the function .... What data type should be the function arguments so I can use them to set a value for a control in any form .
In example : If the Dlookup() is somehow successfull then I want to assign the varSetValue to the txtTest what should I do : FormName.ControlName.Value = varSetValue >??????
I have read a lot materials but couldn't find a good answer for that , and aswell what data type should be the arguments that the function accepts and how do I obtain Controls and Forms names so I could use them in the function as described above .
I have the following function that I found online. Unfortunately I can't remember where I got it since I've had it for a little while. Today, when I tried to actually put it to use it didn't work.
I'm calling it from a form as follows: CompactDB (tblHotword)
tblHotword is just a random table from the back end. My understanding of the function was that it would use that table to connect and get the file name of the back end.
Whenever I run it, Access pops up a window that says "Object required" and nothing else. It doesn't look like a standard error message popup. When I click 'OK', Access continues with the rest of the code as if nothing went wrong. The function doesn't run though.
Code: Public Function CompactDB(TableName As String) As Boolean On Error GoTo Err_CompactDB Dim stFileName DoCmd.Hourglass True stFileName = db.TableDefs(TableName).Connect
I am using a public function to feed a variable string to a query. So far I have got:
Code: Public Function ClientStreetModule(firstLVar As Variant, streetVar As Variant, newFL As Variant) As String Dim cslStr1 As String, newStreet As String newStreet = Right(streetVar, Len(streetVar) - Len(newFL))
[code]....
However, I only need to use newStreet as the true part of iif, in which instance all are longer. At least I think this is the problem. I realise I might need to use NZ but am not sure how. Why it is evaluating and giving errors for all records and not just when the iif criteria is true as I want it to?
I have a table with only two fields and one record: BegDate and EndDate (beginning and end date of the reporting period respectively). I also made a function with variables that look up those values for use as a date parameter in a query.
Here is the code:
Option Compare Database Option Explicit Public Function getCurrentRepDates() As Date Dim dtBegDate As Date dtBegDate = DLookup("BegDate", "tblCurrentRepDates")
[Code] ....
I am getting a syntax error for the line marked red. How can I use "Between" function in VBA code? Access 2010
When UseDDelivery is checked the three textboxes should be disable and when the form is opened UseDDelivery is set to be checked by default so the textboxes should be disabled when the form opens but they aren't. the two different ways of doing it are shown below.
Elements specific to my system :UseDDelivery = checkbox AltDeliveryAddress = textbox1 AltDeliveryTown = textbox 2 AltdeliveryPostcode = textbox3 Solution 1:
This is a bit of vba a friend wrote for me quickly, it includes all three textboxes but the checkbox enables them instead of disables.
solution 2:
Code: Private Sub UseDDelivery_AfterUpdate() If AltDeliveryAddress.Enabled = True Then AltDeliveryAddress.Enabled = False Else AltDeliveryAddress.Enabled = True End If End Sub
With this bit of vba I found the checkbox enables the textbox instead of disabling it and I can't figure out how to include the other two textboxes
I'm new to VB and am learing slowly with all your great help in this forum.
I'm wondering if its possible to write a Public Function for vbCRLF. I have a field in multiple forms that are all named 'Note'. If I have the following code:
Public Function PubNoteLF() On Error GoTo PubNoteLF_Err
My!Note = My!Note & vbCrLf
PubNoteLF_Exit Exit Function
PubNoteLF_Err MsgBox Error$ Resume PubNoteLF_Exit
End Function
When I run the code I get Compile Error: 'Sub or function not defined.'
Can someone tell me what I'm doing wrong? Its problably something real basic, but I'm stumped. Thanks.
I haev a report with 15 sub reports. I have to use Visual Basic to format the sub reports. I know how to do the formatting (see below) but what I would like to do is have one function (Public) that I can pass the subReport name to and have the formatting happen. This would be mush easier to maintain than copying the code below into on_print events of all 15 sub reports.
Has anyone done this and have an example??
Thanks

I have a query that I'm working on through Access 2010's design view. I'd like to add a criteria to the query where it only shows results with the employee name column matching a global variable I created that stores the name of the currently logged in employee.
Here's my vba code that declares the global variable and the public function i'm trying to pass as criteria in the query:
Global gbl_loginName As String Public Function returnName() As String If IsNull(gbl_loginName) Then returnName = "test" ' dummy account created for development only Else returnName = gbl_loginName End If End Function
and here's the SQL code from Access's design view:
SELECT [Entry of Hours].WC, [Entry of Hours].[Employee Name], [Entry of Hours].[Set Up Time], [Entry of Hours].[Run time], [Entry of Hours].[Traveler Number], [Entry of Hours].[Entry Date], [Entry of Hours].[Quantity Finished], [Entry of Hours].Notes, [Entry of Hours].WPS,
[Code] ....
when I try running the query, however, I get this error:
'returnName' is not a recognized built-in function name
Is there a problem with using public functions in Access' design view?
I'm trying to get a public function to work within the design view of a query. The function is defined as:
Public Function Percentile_(fldName As String, _ tblName As String, p As Double, _ Optional strWHERE As String = "") _ As Double... ( I can put the whole code if u need it)
Any thoughts about how I can make the Percentile function calculate values according to a GroupBy statement and not for whole data set?
I have used Allen Browne's code (see http://allenbrowne.com/ser-16.html, bottom of page) as a model for my user-defined type and public function in an events management database.
Using the function in forms/VBA works fine.
But my DB crashes whenever I try to use it in a query.
My modules code: = = = Option Compare Database
Public Type EvCheks EvType As String EvAttCat As String EvUnitAss As String EvCheksAll As String End Type = = Public Function getEvCheks(EV, EvUnit) as EvCheks
'Event Type: Event or DL If (DLookup("evtype", "tblevents", "[evid] = " & EV)) = "Event" Then getEvCheks.EvType = "Y" Else: getEvCheks.EvType = "N" End If
'Event Attendance Category: INDB= in database or LIST If (DLookup("evattcat", "tblevents", "[evid] = " & EV)) = "INDB" Then getEvCheks.EvAttCat = "Y" Else: getEvCheks.EvAttCat = "N" End If
'Event Assessing Organisation Dim AOROName As String Dim AOName As String AOROName = DLookup("evunitassessable", "tblevunits", "[evunitid] = " & EvUnit) AOName = Mid([AOROName], 1, InStr([AOROName], "/") - 1)
Select Case AOName Case "NA" getEvCheks.EvUnitAss = "N" Case "ABCD" getEvCheks.EvUnitAss = "Y" Case Else getEvCheks.EvUnitAss = "X" End Select
getEvCheks.EvCheksAll = getEvCheks.EvType & getEvCheks.EvAttCat & getEvCheks.EvUnitAss End Function ==== On a form, I have a button with on-click event code that defines the EV and EVU variables and displays a message box MsgBox getEvCheks(EV, EVU).EvCheksAll
This works fine. ===== In a query I have this SQL code: SELECT tblEvUnits.EvId, tblEvUnits.EvUnitID, getevcheks([evid],[evunitid]) AS EventDetails FROM tblEvUnits;
This causes the db to crash.
I cannot get the "back-end" definition of the function into the query, as Access rejects it because of the dot, i.e. ".EvCheksAll".
I suspect there is some formatting quirk for using a public function that includes a user-defined type, in a query.
I created a Public Function called fNetWorkDays in my access database, however, when I try to use it in an expression I get "Undefined function 'fNetWorkDays' in expression". The Public Function is in a standard Module in my vba project. Why I cannot call it in my queries?
I have created a Public Function that would get a new Production Instructions number based off the [PI Number] of Tbl_Production_Instruction table.
I have a form that people will put in all information but the PI Number, then when ready they will click a button to update the PI Number. I place an unbound txtbox that will be hidden, with the control source to =NewPINum(), but when I tested the see if the unbound txtbox was populated with the new PI Number it was blank.can't figure out what I am doing wrong.
Code: Public Function NewPINum() As String Dim vNum As String Dim strYYMM As String Dim getnextPI As String strYYMM = Format(Date, "yy") & "-" & Format(Date, "mm") & "-" If strYYMM = Left(DMax("[PI Number]", "Tbl_Production_Instruction"), 6) Then vNum = Right(DMax("[PI Number]", "Tbl_Production_Instruction"), 3) vNum = vNum + 1 getnextPI = Format(Date, "yy") & "-" & Format(Date, "mm") & "-" & Format(vNum, "000")Else vNum = "001" getnextPI = Format(Date, "yy") & "-" & Format(Date, "mm") & "-" & Format(vNum, "000") End If End Function
In my application I have continuous form with unbound textbox. In OnOpen form event I change ControlSource property of textbox to one of the fields (e.g. "Kol921") in forms recordset. In form footer I have another unbound texbox where I defined ControlSource property as "=Sum([Kol921])".
Values in fields shows correctly, but in "sum" textbox I get Error.
When I get through code in debugging mode (with F8 key), value in "sum" texbox shows correctly, but when I open form normally I get an Error in that textbox.
Here is part of code: Me.Controls("mat1").ControlSource = "Kol921" Me.Controls("mat1").Visible = True Me.Controls("matSum1").ControlSource = "=Sum([Kol921])" Me.Controls("matSum1").Visible = True
no problem about setting a different border color for a single textbox (or combobox or listbox) which has focus. How about to change, with a small and fast VBA code avoiding to write code for each textbox, the border color (ora other textbox properties) for a many controls in a form?
I tried using 'For each ctrl in Form....', but I got only bad results. All my control are within differente pages in TAB control.
I have a form with two textboxes that get their values from two different queries that counts records from table. If textbox1.value equals texbox2.value the textbox2.value back ground colour is green. If they are not equal textbox2.value goes red. Itried with using conditional formatting, but it doesn't work all the time as the form is not updating when it is opened.
I have a table with 2 fields. One field is hundreds of hyperlink paths to folders on my computer. These hyperlinks all have their "Texts to Display:" the same as the path to the folder. In my second field I have the desired "Texts to Display:" for Field 1.
As far as I know you can only edit the "Texts to Display:" of hyperlinks 1 by 1. I was wondering if there is a way for me to replace all the display texts with the text located in field 2 all at once? OR if I can add the hyperlink path from field 1 to all the display texts in field 2.
I have a database with various tables containing information about students, timetabling, assignment submission dates and multiple tables with grades for various assessments. All grades are held as percentages.
In a large number of different queries / reports I want to output the grade as an item from verbose scale with 17 points (excellent first, high first etc.). I've set up a table called 17pointscale which contains fields called 17pointscale (with the verbose names), lowerlimit (number) and upperlimit (number).
I have a query in SQL (which works) to take the percentage grade from one of my grade tables AssessedWorkGrades.Grade and return the text on the 17 point scale.
SELECT AssessedWorkGrades.Grade, [17PointScale].[17PointScale] FROM AssessedWorkGrades LEFT JOIN 17PointScale ON ([AssessedWorkGrades].[Grade] >= [17PointScale].[LowerLimit]) AND ([AssessedWorkGrades].[Grade] <= [17PointScale].[UpperLimit]);
Is there any way of converting the SQL to a custom vba function which would enable me to use this as a lookup in a large number of queries.
I think that it should be possible to set up a function called ScaleGrade and in any query Expression: ScaleGrade(XXX) will take XXX and return the 17 point scale.
I think that AssessedWorkGrades.Grade needs to be replaced by a variable that is inputted on use of the function but am not sure how to accomplish this.
Trying to run a query where each 4 fields calling a custom function will not just re-run the same custom function over and over again for each field in a single record.
A Function has a huge amount of multiple queries and logic to perform.The Function returns a Integer, Integer, Integer, and optional Integer. Each integer requires a DLookup to lookup a String description value for each individual integer (in each of 4 fields).
The problem is, the DLookup in each column that runs against each of the integers re-run the same function.The result is that a single record, each of the 4 columns returning a single of the 4 values, the complex function is re-run 4 times.
The function is huge, part of a Business Rules Engine. Depending on the Rule-Meta data - it might launch up to a dozen queries and perform logic steps for each record. This is not the ordinary SQL Query.
Imagine if one record (for 1 field) takes 0.1 second to run. By referencing the function in 4 columns, this same function is re-run 4 times (0.4 Seconds) Against 50,000 records - this duplication of re-running the function for each column can really add up.
Possible Solutions: Researched Class Modules - There is a comment that the property Get, Let actually reduce performance. There are huge advantage of code documentation, documentation and centralization.It doesn't claim class modules reduce execution as each propery is returned. It also describes that Class Modules can't be called directly in a Query - unless each property is wrapped in a function.
Function Returns one String with delimiters: e.g 34;54;55;1 This single column goes into a Make Table (runs function one time per record) Then the D-Lookup is run against static local data. This pevented the function from being run over and over across the network linked data.
Final Solution: Eventually, the many hundred lines of VBA code for the Rules Engine will be converted into SQL Server T-SQL Functions on the server.For a Rule Engine development, Access has been great for a rapid protoype development and testing. The TSQL will be a final big step requiring re-coding. It is not currenty my option for the delivery time frame.
I have a form (Form4) which has a a list box (list11) that allows multi select. When I select on the records I need I hit a button that opens a form up with the selected records. This form is a continuous form. I have an unbound combo box (Combo55). Its values come from a specific table. I want to hit a button and change the field "Assigned" on all the records showing to the value that I selected in Combo55.
The problem is it only changes the value of the currently selected record. How Do I get it to change the value of all records that are showing?
I am only testing this idea with default field names. Before I implement the database I have to get a working model and present it. So I am building this and naming at the moment isnt important.
I am attempting to make a macro to pull information based on a clicked button to provide information to another form. While my example below will be rudimentary, I am attempting to create so that it can be applied to 450 buttons, hence the need for it to be a macro and not simply code per button.
For example if I have 3 buttons, captioned: red, green and blue. If I click on the blue button, it will open another form with a text-box that will say 'blue'. Likewise, if I click the red button the text-box will be changed to 'red'.
In the code below the section that I need to change is: Command1.Caption. Using this data I can pull from the one button to create the value, but I need it to be based on an OnClick or something in order to pull the value from the right button.
Question 2: I am trying to use a query to change button colour on the basis of values stored in a table.What I want to do is change the button background after comparing the button name to the same variable in a table, and determining another variable.
IE: Button1, Button2. In table: Button1, Val = Y, and Button 2, Val = Z
Pseudo Code: Array: From Button1 to Button2 Query for Button1 against table If Val = Y, Button1.background = red Else if Val = Z, Button1.background = blue Else Button1.background = black End if
Code: Select distinct [tbl_DTP/CTP].id_zlecenia, [tbl_DTP/CTP].Folia_na_lakier_UV, [tbl_DTP/CTP].Wykrojnik, [tbl_DTP/CTP].Makieta, [tbl_DTP/CTP].Matryca_do_tloczenia, [tbl_DTP/CTP].Matryca_do_zlocenia, [tbl_DTP/CTP].kalka, tblGoraZleceniaRoboczeLaczenie.NumerZlecenia from [tbl_DTP/CTP] inner join tblGoraZleceniaRoboczeLaczenie on [tbl_DTP/CTP].id_zlecenia = tblGoraZleceniaRoboczeLaczenie.NumerZlecenia where tblGoraZleceniaRoboczeLaczenie.NumerZlecenia = r1;
Where "r1" is a public variable as string.The variable has value e.g. "10/145" But query can't get this value and all the time ask about value from "r1" :/
