Calling Function In External Module
Jan 4, 2006
Is there a way to call a function stored in a module in the back-end access file from within a form in the front-end access file?
I want to be able to slip in a change to the code, and not have to then copy the changed module out to every front end file.
I am thinking that this is something that is in fact trivial to do, but for the life of me, I am drawing a blank on how to do it. Or even what search terms to use to search the help files.
Any help is appreciated.
Thanks,
David

I have created a module with a function that capitalizes the third letter in words that begin with "Mc". I have a table with the city field all uppercase letters. I created an update query that takes the field and correctly changes it. How you would go about tying this function to the textbox on the input form. So, if a user incorrectly enters "mccoy" in the City Field the function would be called and would automatically change it to "McCoy".

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
--------------------------------------------------------------------------------------
Private Sub GroupHeader0_Print(Cancel As Integer, PrintCount As Integer)
Dim widthOfBox, startLeftSide
startLeftSide = 0.017
widthOfBox = 0.21
Me.ScaleMode = 1
Me.ForeColor = 0
'Repeat the following line of code for each vertical line
' 1*1440 represents 1 inch
' Me.Line (0 * 1440, 0)-(0 * 1440, 14400) 'Draws line at Left Margin
Me.Line ((startLeftSide * 1440) + widthOfBox * 0 * 1440, 0)-((startLeftSide * 1440) + widthOfBox * 0 * 1440, 14400) 'Draws line at Left Margin
Me.Line ((startLeftSide * 1440) + widthOfBox * 1 * 1440, 0)-((startLeftSide * 1440) + widthOfBox * 1 * 1440, 14400) ' Draws next line
Me.Line ((startLeftSide * 1440) + widthOfBox * 2 * 1440, 0)-((startLeftSide * 1440) + widthOfBox * 2 * 1440, 14400) ' Draws next line
Me.Line ((startLeftSide * 1440) + widthOfBox * 3 * 1440, 0)-((startLeftSide * 1440) + widthOfBox * 3 * 1440, 14400) ' Draws next line
Me.Line ((startLeftSide * 1440) + widthOfBox * 4 * 1440, 0)-((startLeftSide * 1440) + widthOfBox * 4 * 1440, 14400) ' Draws next line
'the 14400 is an arbitrary number to increase the line to the max of a
'section.
End Sub

I have 28 combo boxes on a form, which I want to insert data into the table as they are changed. Each one will pass the same sets of data just with different parameters which come from the form.
Rather than putting the same code to insert on each of the 28 combo boxes I thought it would be easier to create a function to do it and pass the parameters to it through a sub on the AfterUPdate event of the combo box.
I need to pass 4 parameters, if I only put 1 in there it works fine, but when I start putting more in it doesnt work and I get compile errors or syntax errors.
Sub routine:
Code:
Private Sub cboMonday1_AfterUpdate()
If Me.cboMonday1 = 1 Then
Me.cboMonday1.BackColor = vbGreen
Me.cboMonday1.ForeColor = vbBlack
[Code] .....

My title may not accurately express my question. If you can suggest a better way to do this, please feel free to elaborate.
Within Access, I have an "Invoice Number" table, with a single field containing a number. I have a function that accesses the table, increments the number and returns it to the invoice number field.
I need a way to perform this same function to the same table from within WORD.
I appreciate your time and interest.

Hi,
In the query field i am putting: -
Consecutive Months: Query_Month_Consecutive([Report_2_group_data].[Availability], array([Monthly_availability_CT].[12],[Monthly_availability_CT].[11],[Monthly_availability_CT].[10],[Monthly_availability_CT].[9],[Monthly_availability_CT].[8],[Monthly_availability_CT].[7],[Monthly_availability_CT].[6],[Monthly_availability_CT].[5],[Monthly_availability_CT].[4],[Monthly_availability_CT].[3],[Monthly_availability_CT].[2],[Monthly_availability_CT].[1]))
Basicly the values of them fields are entered into the query, all fields exist and everything is ok.
Anyhow the function is not loaded, i have tested with a simple msgbox and it does not do it.
However when i simply do
Consecutive Months: Query_Month_Consecutive([Report_2_group_data].[Availability], Monthly_availability_CT].[12)
It works and the msg box appears?
I really need it to be an array for what im doing any help would be great
Thanks

I have never tried passing variables while calling a function so I don't know what the heck I'm doing. I'll give a simplified example of what I'm trying to do. The second variable vRank is reporting properly but the first one vID gets "stuck" on whatever the first item in the listbox is.
Code:
Dim vrt As Variant
Dim upSQL As String
For vrt = 0 To Me.List1.ListCount - 1
If Me.List1.Selected(vrt) = True Then
Call ChangeUp(Me.List1.Column(0, vrt), Me.List1.Column(1, vrt))
[Code] ....

Basically i want the app to open small form that asks you to log in basic combo box to select user and text box to enter password well that works fine and i got it to open my main menu, but depending on whether you are a user or admin depends which menu opens.
So i used an if statement to do that part ie
If user = admin then
DoCmd.OpenForm.......
ElseIf User = user then
DoCmd.OpenForm..........
But because I use an If statement for their password
If TextBox = Password Then
Open form main menu
Else
RunMacro (displays an error message)
So I use the password one first but then i need the other to run in the place of opening the form, so in ecense
If TextBox = Password Then
Open form main menu ----- but instead of this line i want
If user = admin then
DoCmd.OpenForm.......
ElseIf User = user then
DoCmd.OpenForm..........
Else
RunMacro (displays an error message)
but it will not work, if i could get a line to run the menu select i could put it in the password one
hope this all makes sense

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
[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'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 created this function to manage a MsgBox containing all required fields with no data:
Code:
Function FormValidation(TheForm As Form) As Boolean
Dim boolResponse As Boolean
Dim strError As Variant
Dim ctl As Control
boolResponse = True
strError = Null
[code]...
Then, I have a Form_BeforeUpdate event, where I wanna place the function, which contains also some VBA code to manage duplicates records:
Code:
Private Sub Form_BeforeUpdate(Cancel As Integer)
Dim rst As DAO.Recordset, dbs As DAO.Database, strICAO As String
Dim ctl As Control, txtMsg As String
[code]....
Now, how to add the function in this event to get these two results:
1. if required fields are blank and I press OK on the MsgBox, the routine must stop;
2. the focus must go in the first required blank control.
I tried some options but I get different kind of malfunctions: no custom message for duplicate records but only the access default one, "go to next record" feature with tab key not working and so on.

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 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?

Hi. I am creating a contact management database. Also I am new to Microsoft Access. How would I create a calling history record for each of the clients in the contact database? What would be the best way and how would I go about it? The calling history ideally would include the call recipient, time, date, subject and notes. Thanks. Take care.

Hi All
Nice to find a forum which helps ppl new to VB access 'like me' :). I appreciate any help in this regard.
I generated a report from a query. I would like to modify this report by adding parameters pertaining to 'another' query (say query num 2). There is no relationship between these two queries. How do I call the 'other' query (query num 2) thru VBA and modify its parameters.
Thanks alot in advance

I have a series of IF statements that check my fields and if null call a message telling the user a value must be filled in before the record cab be saved. The code works fine. Here is the code for two fields to show the syntax:
If Len(Me.FName.Value & "") = 0 Then
MsgBox "You must enter a value into FName."
Me.FName.SetFocus
ElseIf Len(Me.LName.Value & "") = 0 Then
MsgBox "You must enter a value into LName."
Me.LName.SetFocus
This same code repeats for each field.
Here is my problem. I have Home, Work and Cell phone fields. The client may not have these numbers. I want to add code that add code for these fields that calls a message box with 2 command buttons(yes & no) with the Message" Does the client have a Home Phone?"
The user would choose the yes or no command button. If the user chooses yes then the same code as above would be called. if he chooses no the ElseIf statement would be called. Can this be done? I don;t know how to wriye the code for the command buttons. can anyone help?

Hi,
I'm having problems calling a simple query from the VBA associated with one of my forms. The code goes thus:
Private Sub Form_Current()
Dim rs As Recordset
Dim db As Database
Dim qryMaxAlp As QueryDef
If Me.NewRecord = True Then
'query database here and find out next alp_key
Set db = DBEngine.Workspaces(0).Databases(0)
Set qryMaxAlp = db.QueryDefs("qryMaxAlpKey")
Set rs = qryMaxAlp.OpenRecordset()
Else
End If
End Sub
The problem occurs on Set qryMaxAlp = db.QueryDefs("qryMaxAlpKey") where I get the error "3265 Item not found in this collection". However the query does exist, and when I run it independantly works fine (it brings back the maximum primary key of a linked table.
So, what am I missing?

Hello.
I have a database that runs a fews tasks for me me when no one is in the office as the systems are quicker and the admin work tedeous and boring, yet necessay. The problem Im having is in calling a database. The problem stems, i think, from the names on the folder. Unfortunately renaming isnt an option because its got many hundreds of users on the server and I dont have the admin rights besides.
The error is coming on .......
Call Shell("msaccess u: eam-shared-dataRes. SalesOutsourceOutsource_DbsDatabase_StoreOutso urce.mdb").
The error message I get says that u: eam.mdb isnt valid .... when its not. The error is caused presumably by the " - 's " and probable after it passes this the " Res. Sales" will cause an error too. So my question Im asking is, is there anyway to make the path read in full, I've tried preceeding with < and ending with > and "" or even ' but still no joy. Can anyone please help, its getting annoying now. :o :confused:

Dear Access Chart Expert
I have been trying to figure out how I can make the x-axis show month abbreviation names instead of numbers. Please see attached gif.
Currently, I use the Month([DateField]) function to get numbers of the month because if I use Format([DateField], "mmm") to get "Jan, Feb, March" the chart sorts the months in alphabetical order instead of the correct monthly order.
How can I be able to use the Jan, Feb etc... labels and have the chart sort them in the correct month order and not alphabetical order?
Thanks so much...
greatly appreciated.
