Modules & VBA :: Counting Input In A Subform?

Sep 11, 2013

i have a field in the form where you can choose how many vehicles you have in the contract.

the field is called

amount_vehicle

Then i have a subform where you put the vehicle in.

So there is a 1 to n relation between the form and the subform

The id of the vehicle is called ID vehicle

I want that e.g a user chooses 2 vehicles in the form. Now it is not possible to put in 3 vehicle in the subform.

I�ve created the following code, but it doesnt work.

[CODE]
If DCount("*", "subform", "ID vehicle = " & Me.Parent!ID vehicle) >= Nz(Me.Parent!amount_vehicle, 0) Then
MsgBox "no vehicle"
Cancel = True
Me.Undo
End If]

Forms :: Counting Checked Boxes In A Subform

Feb 18, 2014

I have set up a database to record several different sets of records for a volunteer group that I run. The types of records that I am keeping are hours on duty, uniform issued and attendance at training. The attendance form is a subform which contains a list of dates and the two fields of checkboxes showing if they attended or sent their aplogises.

What I am trying to do is to count the number of times that members attended training. I have set up a 'unbounded' text box in the footer and would just like to add a formula in to the command box of the box properties. Anything more i.e. coding then it goes over my head very quickly.

Modules & VBA :: Counting With SQL

Dec 19, 2014

I built a query "WplatyKlienci" which sum all of payments "Sumawplat" from my clients "klient".

Code:

SELECT SUM(tblWycenaZakonczone.cenanetto) AS Sumawplat, tblKlienci.nazwaSkrocona AS klient
FROM tblWycenaZakonczone INNER JOIN (tblZleceniaZakonczone INNER JOIN TblKlienci ON tblZleceniaZakonczone.id_k = tblKlienci.id_k) ON tblWycenaZakonczone.id_zlecenia = tblZleceniaZakonczone.id_zlecenia
WHERE tblWycenaZakonczone.cenanetto is not null
GROUP BY tblKlienci.nazwaskrocona;

Now I need to know 2 things and I have problem with counting in sql:/

1) what percentage of the total amount represents a particular client.
2) I want to create a graph, so I need to do another query, which shows values form no. 1 only for 10 clients with the largest payments + one position named "others" which represents rest of clients

Subform Snubs New Record Input

Jun 22, 2005

One form, two subforms in a new db. The three work well together, except when it comes to a new record.

When I want to input details of a new record, the main form and a subform work ok, but the third subform won't accept anything.

Any guidance, please, gurus?

Modules & VBA :: Counting Value And Assigning Numerical Value?

Aug 15, 2013

I am working on an app, that has a field named "Name". I have everything set up with a module, which, for example, the name "John", it assigns 1. when it sees "John" again it assigns 2. Then "Jane" It assigns 1 again. I want the module to see every instance of "John" to assign the same number, 1, then all instances of "Jane" 2, etc. Here is the code in the module I am using, but it is assigning the values wrong. My final plan is to use the numbers for conditional formatting, so all johns one color, all janes, a different color. I can't use the conditional formatting wizard because these names pop up at random, and the names populate at random.

Option Compare Database

Global GBL_Category As String
Global GBL_Icount As Long
Public Function Increment(ivalue As String) As Long
If Nz(GBL_Category, "zzzzzzzz") = ivalue Then
GBL_Icount = GBL_Icount + 1
' MsgBox icount
Else
GBL_Category = ivalue
GBL_Icount = 1
End If
Increment = GBL_Icount
End Function

Forms :: Subform - Input Box Reappears When Closing Database

Nov 13, 2014

I have a

- form called "Hauptformular" and a
- subform called "qry_tracking_Unterformular". Then there is a
- button called "cb_filialname".

Now when opening the Database, the form appears with the subform containing the
- query "qry_tracking"

When hitting the button "cb_filialname" the subform receives the contents of the
- query "qry_tracking_FilName", that has a filtering option on the Column "Filiale": "Like [Filialname?]"

Now the filtering works fine with the following Code:

PHP Code:

Private Sub cb_filialname_Click()Me!qry_Tracking_Unterformular.Form.FilterOn = 
FalseMe!qry_Tracking_Unterformular.Form.RecordSource = "qry_tracking_FilName"End Sub 

-> when you hit the button, the inputbox

Filialname?

appears.

The problem now is, that after having used the button, when I click the "Exit" cross right up there, the inputbox appears again.

Forms :: Subform With Date Picker To Input Multiple Dates

May 14, 2013

On my main form, I have a subform to input multiple dates, using date picker.

I also have a text box on the main form to input single dates, again using Date Picker.

On entering both the single date text box and the subform, I don't want the (default) date to be visible. I only want the date to be visible once I have selected a date from the Date Picker.

I have figured out how to do this with the single date text box. I have simply defaulted the forecolor to be white so that you can't see the font against the white backcolor. Then on the Change Event, I set the forecolor to be black. Works like a charm.

However... This same approach will not work with the subform. I've tried playing around with a bunch of different events, but so far nothing allows me to re-create what I am able to do with the single date text box on the main form.

Modules & VBA :: Ignore Date Fields In Table When Counting Records?

Jun 6, 2014

Suppose I have a table with a variety of fields; one autonumber, some text fields and some date fields.

I need code to calculate the number of fields that are NOT date fields and then code to count how many of those fields (the ones that are not date fields) have data in them.

Following is the code to count how many fields in a table had data and this works well, but now I need to find a way to ignore the date fields. How can this code be modified to do the same but ignore the date fields?

Code:
Public Function PercentCompleted(Table As String, IDProject As Long, TotalFields As Single) As Double

Dim sampO As DAO.Recordset, iCtr As Long, strSQL As String, Percent As Double
'Takes the fields based on the projectID
strSQL = "SELECT *" & _
"FROM " & Table & " WHERE IDProject = " & IDProject
Set sampO = CurrentDb.OpenRecordset(strSQL)

[code]....

Counting Of Cases And Counting No Records

Jan 26, 2007

I have a report due the first of each week in which I need the cases open and cases closed for the previous week, the week two weeks prior and the 2007 and 2006 year to date on two different types of cases. I have a case management table with a field for Type of Case, date assigned and date closed that I uses in my queries. Presently I have two query, one that generates only Type 1 cases from the Case Management Table and another for Type 2. I then use the Type 1 Query in another query that limits the results for Type 1 cases to those opened last week, one for those open two weeks ago, one for 2006 YTD and one for 2007 YTD. In these 4 queries I have one field [Type of Cases] and I have the query count. I then do this for Type 2 cases and then go through the whole process to do Closed Cases. All my queries have criteria to automatically filter the dates to the time periods mentioned above. I then have one report query that I put all the number in for my report. This query has 16 fields with the numbers for each period, last week open and closed, 2 weeks open and closed, etc. I then generated a report that takes these numbers from my report query and puts it in a report format automatically. As you can imagine this takes some time to go through each query to generate these numbers, so I was wondering how I may do this differently. Also, I have experienced a problem when a field produces no records I get a blank sceen with nothing under the Count of column and get the same thing for my report. How can I fix this.

Modules & VBA :: Multiple Value Input Box?

Jun 12, 2014

How I could do a multiple value InputBox in VBA, if this is even possible... This is so I can prompt the end user to enter a range (with two string values as start and end parameters) for a report I'm working on.

If this is possible, I would like to include this as an additional parameter option within the code I have below:

Code:

Private Sub EmployeesBadges_Click()
Dim soa As Byte
Dim emp, sEB As String
soa = MsgBox("Do you wish to print a single employee badge or all?", vbYesNo + vbQuestion)
Select Case soa
Case vbYes

[Code] ....

I'll just create a form to do this.

I am not sure if this is the most effecient or best or if it has issues that other methods or ways to use but doing this seems to do the trick.

Modules & VBA :: Input From Form Into Code?

Jan 20, 2014

i have being requested to create a from that displays the number of files in different folders. I can accomplish this somewhat with the code below. In the example below it is only showing the code for the first 3 folders. I have 7 folders in total to count.

1.Each week the location of the data will change. In the example below it is showing 2014-W03, the following week it will be 2014-W04 etc. etc. I was thinking of having an input box in the form that the user type the date into, to trigger the code, but how would I go about changing the code to include this variable?

2.I need to repeat this code for 9 other products, so my form will be displaying data for 10 products in total. I know I could copy this code 9 times and modify it accordingly, but is it possible to loop it in some way?

Code:
' Returns the total number of fails
Private Sub Form_Load()
Dim file As Object
Dim fileCount As Long
With CreateObject("Scripting.FileSystemObject").getfolder(" estmachineProduct1 FAILS2014-W03")
For Each file In .Files

Modules & VBA :: User Input Criteria For Union Query?

Aug 20, 2013

I am trying to get my VBA code to dump a query once the user pushes a button. I have the following code to call up the Excel app.

Code:

Option Compare Database
Private Type BROWSEINFO
hOwner As Long
pidlRoot As Long
pszDisplayName As String
lpszTitle As String
ulFlags As Long

[code]....

The qry_PP_Errors_Union is a Union query. In this query there is a date field. I would like to be able to to use that date field as a parameter. So I have written this VBA to prompt the user for a Begin Date and an End Date.

Code:
Beep
strBegindatemsg = "Enter the beginning date." & vbCrLf & vbLf
strBegindate = InputBox(Prompt:=strBegindatemsg, Title:="Begin Date")
Beep
strEnddatemsg = "Enter the beginning date." & vbCrLf & vbLf
strEnddate = InputBox(Prompt:=strEnddatemsg, Title:="End Date")

Now the part that I am missing is that I am not sure how to make the "strBegindate" and "strEnddate" the criteria for the union query.

The following is the SQL for my union query.

Code:
SELECT LastName, FirstName, Title, TeamName, WorkOrderNumber, DateCompleted, WorkCode, UICError AS Error, "Update and Internal Correspondence" AS Category FROM qry_PP_UIC_Error
UNION
SELECT LastName, FirstName, Title, TeamName, WorkOrderNumber, DateCompleted, WorkCode, BIDError, "Bids" FROM qry_PP_Bid_Error

[Code] ....

Without the criteria, my code works for dumping everything out into Excel. However, dumping all the data results in a 7 mb Excel file that requires manual deletion of the information that is not pertinent.
