Modules & VBA :: Using Same Module With 2 Front Ends?
Jun 24, 2015
I have a small system that consists of a back end data base and 2 front ends. having 2 front ends was a historic reason but they cover 2 distinct processes in the system.
I now have the need for using the same module(s) in both front ends. Each has a copy which is fine if nothing changes but when it does I have to apply the changes made (or copy over in its entirety) from one front end to the other.
Although this is no big deal I can forsee it slipping through the net.
Can 2 front ends access the SAME module and if so how?

Hi guys,
I need help with security settings and that. I have a database which i want available on a shared server. Basically i only want people to beable to see one form but not beable to see anything else or make any changes to this form.
Do i need to split and make a front and back end? I will want to make occasional changes to tables etc.. and so would want this to automatically update on the database seen by everyone else.
Sorry, not making much sense but am bit confused about it all!
Any help from some clever peeps?

I have (on a company network) a FrontEnd .accde and a backend .accdb - currently ~ 10 users (some over wifi - slow!)The FrontEnd is becoming a rather large file ~ 10 MB and is also becoming slower.I am looking to separate this in to 3 FrontEnd files as to simplify and to lessen the file sizes etc.
My question is - are there any issues around a 3 x FrontEnd databases all connecting to 1 x backend database holding all the tables - over a network?

How do I hide or disable the File tab in Access 2010 on my front ends?
The file tab being present allows end user to get into Privacy Options and Printing. Printing is okay if I could disable the Privacy Options for end users, then it wouldn't matter if they have access to the File Tab.
Possible very serious security issue!

My question encompasses a front end connected to multiple back ends. It is probably a mundane point, but reading a few articles didn't seem to touch on it.
By this, let me toss out that I am thinking of the personnel where I work when I say 95% have a hard time using email and MS Word, let alone mundane functions like find a file, etc. As such, I have to make my front-ends extremely user friendly.
With that in mind, when developers have multiple back ends, what are thoughts about the best way to relink when required? Even when there are 'more sophisticated' users? Security not an issue or is an issue (inasmuch as can be handled in access)?
Ex: Large corporation with a multitude of user ability. Large database with say 3 different back ends.
I was thinking about keeping a front-end table with each table name and UNC path, hard coding paths to corresponding table names, etc.
Personally I don't have a need for multiple back-ends, but the question came up while reading.

I have a combo box that contains a list of values, but users can add their own if they choose. If the value they type in isn't on the list, the Not In List event fires. Once the procedure is done, the form inexplicably closes.
Oddly enough, it only closes under certain circumstances - the code provides several different options for saving the new data, and if I choose different options, the form works as its designed.
Further, if I insert a breakpoint anywhere in the code, then hit F5 to let the code run, the form works fine. Literally, the breakpoint can be anywhere in the procedure from the first line (On Err...) to the last line in the Exit block, "Exit Sub".

I'm wondering how other members here make decisions whether they want to place codes behind form or use a standard module instead.
I understand there is a performance penalty when you add another module (and use it), but am not sure whether one big fat module would be faster than several smaller modules with identical coding.
Furthermore, I know that some members use a hidden form to deal with startup and shutdown processing. Sometimes the processing has nothing to do with forms and would make more sense in a standard module, but since the form is already loaded, does it makes more sense to use the module behind the form than calling a function in a separate standard module to execute the needed code?
So, what do you tend to do in such situation?

I have this code below that is working however the calculation are updating on my form late.
Basically, I have some calculation that are performed on a "After Update" event on some controls on my form. I wanted it to do the calculation after I update the control on the form.
The code is in a module and I just call the function after update on the control But the form is not updating when I change the value in a field. I have to change the field again for it to update.
Control
Code:
Call GeraAuditCalc
DoCmd.RefreshRecord
Function
Code:
Function GeraAuditCalc()
Dim fHrs As Double
Dim Ttl As Double
Dim Ttl1 As Double
Dim Ttl2 As Double
[Code] ....

I am trying to return a value in an expression (call it FundedPeriod): CurrentWeek, CurrentMonth, PreviousMonth, based on a date value in field [funded_date].
Here are the criteria I am using:
Current Week: DatePart("ww", [Funded_Date]) = DatePart("ww", Date()) and Year([Funded_Date]) = Year(Date())
Current Month: Year([Funded_Date]) = Year(Now()) And Month([Funded_Date]) = Month(Now())
Previous Month: Year([Funded_Date])* 12 + DatePart("m", [Funded_Date]) = Year(Date())* 12 + DatePart("m", Date()) - 1
Based on example, I expanded upon that and came up with this:
Code:
Function FundedPeriod(FD)
' returns CurrentWeek or CurrentMonth or PreviousMonth or None based on FundedDate (FD) criteria
Dim ret As Boolean
ret=CurrentWeek
[Code] ....
Am I in the ballpark w/ this in order to return:
CurrentWeek or CurrentMonth or PreviousMonth
so in the query expression I think I would type FundedPeriodName: FundedPeriod([funded_date])

How you automatically initialize a newly instantiated class?
So when you create a new instance it will run a procedure to set attributes.

I have the following module in my database to allow for multiple alarms.
It all works great, except before showing the actual alarm record called, the form first pops up showing the first record in its record source.
I.e. it flashes up showing the first record in the table, then changes to the 'correct' record.
I would just like to change it so it either doesn't show until the record is loaded, or it shows blank to begin with.
Here's the module...
Code:
Option Compare Database
Option Explicit
Public clnPopUpAlarm As New Collection 'Instances of frmPopUpAlarm
[Code].....

I am trying to pass a boolean variable to a class module
Code:
Set rps.ViewS = View
the code in the module that this in theory is calling reads as
Code:
Private ViewC As Boolean
Public Property Set ViewS(ByRef ViewA As Boolean)
Set ViewC = ViewA
End Property
Public Property Get ViewS() As Boolean
Set ViewS = ViewC
End Property
However I am getting the error message
Quote:Definitions of property procedures for the same property are inconsistent, or property procedure has an optional parameter, a ParamArray, or an invalid Set final parameter.

I'm trying to monitor a few fields and record who updated them together with the old and new values, so far, I have this;
This does work ok, I was just wondering if there's a way of referring to the current field, rather than having to specify 'me.NPW.oldvalue' etc.
Code:
Private Sub NPW_AfterUpdate()
Call LogFieldUpdate(Me.AppNumber, "NPW", Me.NPW.OldValue, Me.NPW)
End Sub
[Code] ......

This module is giving me the "undefined function" error message when I try to run my query. I don't know why, but I have checked that there are no references with "missing" and there are not. I also added the word "Public" to the function becasue that was advised by another forum user. I thought it worked perfectly the first time I ran this query, but now it is not working and I do not recall making any changes. I have called the module basFunctions:
Option Compare Database
'************************************************* *********
'Declarations section of the module
'************************************************* *********
Option Explicit
'================================================= =========
' The DateAddW() function provides a workday substitute
' for DateAdd("w", number, date). This function performs
' error checking and ignores fractional Interval values.
'================================================= =========
Public Function DateAddW(ByVal TheDate, ByVal Interval)
Dim Weeks As Long, OddDays As Long, Temp As String

I have a back end database that a number of people are working with using an Excel add-in that imports and edits records saved in the backend. Occasionally, when a user will update a record at first it saves to the backend but then an hour or two later, the changes made disappear. We have validated that after the user saves the changes, those changes are present in the backend of the database, but for some reason those changes disappear after a period of time.

Can't find any way to declare variables in the sort of module that Access uses by default.Having changed the default, I now get 'Option Compare Database' as the first line (previously nothing was there). Adding anything at all in that section, or changing it to 'Option Explicit' has the consistent effect that all the procedure names in the module are not recognised and nothing works.
Variables declared in procedures work only in the procedure even if declared as Public. Can't get a Static variable to work in more than one procedure. However many variables I declare, there are never any in the Declarations list at the top of the Code Window.

I am trying to create a customizable report that would allow the users to choose fields. I have a pretty common code that I found online and adapted it, but it fails on the first SetReportControl function.
The error reads: Run-time error 2465: Application-defined or object-defined error
Could it be something as simple as an incorrect reference? I have checked multiple times, but I am stumped.
Code:
Option Compare Database
Option Explicit
Sub MakeReport()
[Code].....
This is a trial run, in the end I need to be able to open a report, then adjust the Report controls within 1 or more subreports inside the main report. That is a battle for another day.

I am creating an form in a database and whenever one of my procedure's run it creates this error message:
The expression ON Load you entered as the event property setting produced the following error:
Member already exists in an object module from which this object module derives.
*The expression may not result in the name of a macro, the name of a user-defined function, or [event Procedure].
*There may have been an error evaluating the function, event, or macro.
An ideas?

I'm looking for some type of custom function that will search a specified column for any keywords listed inside another table.
I can run a query on each keyword individually, however there are 50 and it takes a long time each time I do it. I was hoping to write in a function for that column and it would just select all records that match.
These would all need to be a "like" with an " * " on each end of the word.
With SQL it would look something like:
Code:
select a.address1
from main_tbl as a
where a.address1 like '* north *'
or a.address1 like '* park *'
or a.address1 like '* south *';
I just want it to read each of the table values instead of hard coding them and the column name would be the function name so it can be used in any column I specify. I'm just not sure how to incorporate this into a custom function.

I am after a script to lock a userform to the front but still be able to work on other forms.
I have an excel userform in access which does this and better still it is like a sticky note as it stays on the screen even when going to another program, but as I am working in vba all day long, every time I change something the form closes, it works great when not using vba though.
