Quick Easy Question, RE Error With Simple Code

May 24, 2007

hiya every1, (access 2k3)

quick easy question, as im a noob when it comes to coding/vb.

Within our company database we have the usual timesheet table. With the table I have create a query (called "dailytimeforkeith") that gives me the sum of time for an individual person for one day (in fact its the previous day). What I have done then is created a form (called "keithyesterdaytime") that shows this query entry (called "sumoftimespent").

Each user has a different database screen logon and forms that are present when they log in. So what I then done is on one of these forms the load up, i attached this:

Private Sub Employee_Enter()

Me.Employee = User.FirstName


If Me.Employee = "Keith" Then

Dim stdocname As String

stdocname = "keithyesterdaytime"

DoCmd.OpenForm stdocname, , , acAdd

............



then on "keithyesterdaytime" opening the following code runs
------------------------------------------------------------

Private Sub Form_Open(Cancel As Integer)

Dim internal1 As Integer

internal1 = Forms!keithyesterdaytime.SumOfTimeSpent

If internal1 < 6 Then

DoCmd.Close

MsgBox " Less than 6 hours have been entered " & Chr(13) & " into your timesheet for yesterday. ", vbCritical, Title1

Else

DoCmd.Close

End If

End Sub
-------------------------------------------------------

Whenever i logon with the user keith, i get the following error 'runtime error 2427: You entered an expression that has no value.

If I open the form "keithyesterdaytime" on its own, the code works and i dont get an error.


What have i done wrong, and be gently. HEHEHE. Also is there any easy way i can do this instead of having to create the the form "keithyesterdaytime"

Error Trapping

May 14, 2005

I have the following in the after update event in a Combo bound to a tbl on a Main form;
Sub Combo8_AfterUpdate()
' Find the record that matches the control.
Me.RecordsetClone.FindFirst "[Vendor] = '" & Me![Combo8] & "'"
Me.Bookmark = Me.RecordsetClone.Bookmark
End Sub

The Combo gets its data from a table and I use the Not In List to add data which is not in the Tbl and of course Limit To List is set to Yes.
It works ok with one exception, when data is entered, but not saved, then deleted And the form closed. In this set of circumstances I get an error in the code above. Granted that normally a user will not delete data from the combo then exit the form but it does happen occasionally. I have tried adding On error goto.... but with no luck. Any suggestions?

Trapping Error 3022

Jul 31, 2005

My table has an auto generated key as a string.

So on the offchance that two clients are trying to autogenerate a key at exactly the same time, I'm trying to trap the 3022 error raised when a duplicate key is entered so that I can repeat the operation with a goto.

I'm raising the error with requery like this:


DoCmd.Save acForm, Me.Name 'next line triggers 3022
DoCmd.Requery


After I realised that the normal handler wouldn't trap it I got the database from this thread:

http://www.access-programmers.co.uk/forums/showthread.php?t=77529&highlight=3022

But it doesn't seem to work for me:

Anyone?

Trapping A Validation Error

Jun 22, 2006

Hi,

I have a VBA code that runs an append query to update a table. Due to relationship integrity a validation error shows (a type does not exist in the connected table): What I want to do is trap the error and write something that the user can understand. Help !


The Code:
Code:Private Sub Report_Deactivate()Dim Msg, Style, Title, Response, MyStringMsg = "Click OK to Import Verified Data to the Invoice Table"Style = vbYesNo + vbMsgSetForegroundTitle = "Verify Import"Response = MsgBox(Msg, Style, Title)If Response = vbYes Then 'This is the problem line DoCmd.OpenQuery "qry_Step_5_appending_invoices", acViewNormal, acEdit DoCmd.OpenQuery "Qry_Step_6_update_fob", acViewNormal, acEditElse MyString = "No"End IfEnd Sub

appreciate any help, thanks

Error Trapping Problem

Jan 2, 2007

I have a "homemade" switchboard that I am using and the first page allows the choice of administrator or user. I have used access user level security to deny all but administrators access to the administrator "path" in my switchboard.

When a user clicks on it, they get the runtime error 2603 saying that they don't have access. I am trying to modify the on error event so that the error won't show up and a custom message box I create will show up instead, however I cannot seem to get my on error code to do anything. I always get the standard access runtime error return box. Does anyone have any ideas??

Error Trapping Problem

Aug 6, 2007

I have an "Error trapping" problem.
I am relatively new to VBA and wondered if someone would be so kind and point out the error in my code.

I have a form "frmSelectInvoices" that opens another form, "frmInvoice".

I use the Select Invoices form to select completed jobs that are not invoiced, based on a query.

The user would then select a job that he/she wants to invoice, and "frmInvoice" opens in front of "frmSelectInvoice".

"frmInvoice" is based on "tblInvoices" and a couple of the required fields, (customer, JobID, etc) are filled-in automatically using the information from a couple of fields from "frmSelectInvoice"

"frmInvoice" also has an InvoiceNumber field which tblInvoices needs as it is set as a required field with no duplicates, (this is NOT the primary key).

I am trying to notify the user that the InvoiceNumber has already been used, and to reset the record, so they can enter a new Invoice Number.

The code I have so far is as follows;
Code:Private Sub Notes_Exit(Cancel As Integer)On Error GoTo Err_SameNumber Dim iResponse As Integer iResponse = MsgBox("Do you wish to Print an Invoice", vbYesNo, "SELECT AN OPTION") If iResponse = vbYes Then DoCmd.RunCommand acCmdSaveRecord Forms!frmSelectInvoice!Invoiced.Value = True Forms!frmSelectInvoice.Requery DoCmd.Save acForm, "frmInvoice" DoCmd.OpenReport "rptInvoice", acNormal, "", "[pkInvoiceID]=[Forms]![frmInvoice]![pkInvoiceID]" Me.btnClose.SetFocus Exit Sub End If If iResponse = vbNo Then MsgBox "You can Print it out later from the Invoices Main Menu", , "You Selected NO" End If DoCmd.RunCommand acCmdSaveRecord Forms!frmSelectInvoice!Invoiced.Value = True Forms!frmSelectInvoice.Requery Me.btnClose.SetFocusExit_SameNumber:DoCmd.RunCommand acCmdUndo DoCmd.GoToRecord , , acNewRec Me.fkBookingID.Value = Forms!frmSelectInvoice!pkBookingID.Value Me.fkCustomerID.Value = Forms!frmSelectInvoice!fkCustomerID.ValueMe.InvoiceNumber.SetFocusExit SubErr_SameNumber: MsgBox "Invoice Number has already been used", vbInformation, "Please use a New Invoice Number" Resume Exit_SameNumberEnd Sub
When I test the form with a number I know already exists, or even a number that has not been used before, the error message comes up and it then sets the focus to InvoiceNumber, but when I try and close the form it still keeps coming up and the only way I can get rid of it is to close the application using Windows Task Manager.
Any help on this would be appreciated.
Thanx

Need Help With Rich's Error Trapping Routine

Apr 9, 2007

Hi guys, I was looking for a way to trap err.number 3314 (when required field is null) before Jet generates its warning. I came across an old post from Rich (below), but I couldn't make it work as yet. In the calling form, under the Form_Error event I wrote the following:

Dim f As Form
Set f = Me
Call fnValidateForm(f)

Could anyone please tell me where my error lays here? I have several forms which have several text and/or combo boxes bound to required fields and I would want to have a generic code, like the one here to trap errors before Jet shows it's Error Message.

Thanks in advance
Regards
Jaime Premy - Belém-Brasil

******************Rich's Function********************
Public Function fnValidateForm(frmA As Form) As Boolean
Dim ctl As Control
Dim Msg, Style, Title, Response, MyString
fnValidateForm = True
For Each ctl In frmA.Controls
'value in the control is required
If InStr(1, ctl.Tag, "Required") > 0 Then
' no value entered or value is null
' or zero for numeric fields
If (IsNull(ctl.Value)) Or (Len(ctl.Value) = 0) Then
ctl.SetFocus
MsgBox "You have not entered all the required fields return to the record and correct this! The record will not be saved if you do not! "
fnValidateForm = False

Exit For
End If

If InStr(1, ctl.Tag, "NumberRequired") > 0 Then
If ctl.Value = 0 Then
ctl.SetFocus
MsgBox "You have not entered all the required fields return to the record and correct this! The record will not be saved if you do not! "
fnValidateForm = False

Exit For
End If
End If
End If

Next
End Function

Cancel Query / Error Trapping

Jul 24, 2007

Ok, I have a delete query that I use to delete records form a table. I have created a form that I run that query from. It has Delete button that runs the query. After I get the message that says "You are about to delete 56 records" and I click No, I get a "run-time error '3059'. Operation Cancel by user"

I did some searching on the forum and thought I could trap this error. But I still continue to get the error at

"DoCmd.OpenQuery stDocName, acNormal, acEdit"

What am I doing wrong and how can I prevent this error from appearing when I click NO or cancel the operation.

Private Sub cmdDelete_Click()
On Error GoTo Err_cmdDelete_Click

Dim stDocName As String

stDocName = "qryDeleteRecords"
DoCmd.OpenQuery stDocName, acNormal, acEdit

Exit_cmdDelete_Click:
Exit Sub

cmdDelete_Error:
Select Case Err.Number
Case 3059
MsgBox "You have canceled the delete operation.", vbOKOnly, "Delete Canceled"
Exit Sub
Case Else
MsgBox "Error number: " & Err.Number & " has occurred. " & Err.Description, vbOKOnly, "Error"
End Select

Err_cmdDelete_Click:
MsgBox Err.Description
Resume Exit_cmdDelete_Click

End Sub

Navigation Button Error Trapping

Jun 1, 2005

I've made my own record navigation buttons on a form. they work fine, except when i get to the first record. if i click 'previous' then the 2105 error pops up "you can't go to specified record". the buttons were created through the wizard, and have error trapping in them. for some reason, it never actually goes to the error handler. the error message comes up, i press debug, and the 'DoCmd.GoToRecord , , acPrevious' is highlighted.

any ideas why the error trapping isn't working? here's the code:

Private Sub cmdPrevJob_Click()
Dim x As Variant
On Error GoTo Err_cmdPrevJob_Click
DoCmd.GoToRecord , , acPrevious
Exit_cmdPrevJob_Click:
Exit Sub
Err_cmdPrevJob_Click:
If Err.Number = 2105 Then stop
MsgBox Err.Description
Resume Exit_cmdPrevJob_Click
End Sub

BeforeUpdate Error Trapping Not Working

May 11, 2006

I've got my form working, and all of the record updating is working fine, so now I am working on error trapping. I need to check if any of the two textboxes are empty, or nothing has been selected from the combobox. I am using the BeforeUpdate method. I am not getting any syntax errors. I am using an INSERT INTO SQL statement. Thanks.

related DB fields:
SOPNumber (text)
RevisionNumber (text)
TrainingDate (date/time)


Private Sub Form_BeforeUpdate(Cancel As Integer)

If IsNull(Me.cboSOPNumber) Then
Cancel = True
MsgBox "The SOP number is required", vbOKOnly, "Notice"
Me.cboSOPNumber.SetFocus
End If

If IsNull(Me.txtRevisionNumber) Then
Cancel = True
MsgBox "The Revision Number is required", vbOKOnly, "Notice"
Me.txtRevisionNumber.SetFocus
End If

If IsNull(Me.txtTrainingDate) Then
Cancel = True

Modules & VBA :: Error Trapping For Data Validation

Feb 15, 2015

I am using following routine to lift data from Excel files into Access tables. Whole thing works, well, most of the time. The only issue I have is the spreadsheets are received from warehouses and even though they have been given strict instruction to stick to the template, I have had to adjust the spreadsheets. Amongst errors I get are:

Field 'F16' does not exist in table 'SA1'. (In this case I simply delete the last most empty column to fix this).

Or there are column name spellings and in such cases, I get no error and the simply code hangs.

Is there any routine that I could incorporate in the code that clearly states what issues are being experienced. This way I can pass the db to the user to run it themselves.

'Dim dbs As Database, tdf As TableDef
Set dbs = CurrentDb
On Error GoTo Macro1_Err
DoCmd.SetWarnings False
' RunSQL executes a SQL string

Error From Simple Statement

Jun 5, 2007

Okay, now I'm suspecting there's more to this than an overly complicated control source statement....

My summary report contains multiple objects that calculate totals based on a statement in their control source. The report ran fine for a few weeks but all of a sudden it started producing this error:

"The expression is typed incorrectly, or it is too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables."

I thought perhaps that 12 lengthy control source statements were simply too much for Access to handle, but then I did some testing and eventually removed all but this control source statement: =Sum([NotifType]=9)

That's about as simple as it gets, but when I try and run the report I still get the error. Ggggrrrrrrrrr....

Can anyone tell me what causes this annoying error and how I can get rid of it? (I already compiled.) What little Access quirk am I running into? I will gladly zip the file and post if necessary.

Thank you.

Simple Vb Error Problem

Apr 5, 2006

i'm not very good at vb and i'm sure this is an easy problem but i can't find the answer.
i have constructed a vb code to show images from a stored table [not OLE linked]:

Private Sub Form_Current()
If Not IsNull(Me.combined_image_path) Then
Me.cempic.Picture = Me.combined_image_path
End If
End Sub

this works fine except when there is no image to show, the last image stays visable. what i want is no image to show if no image is availiabe for that record.
i know that the statement should be constructed along the lines of
'then'
if no image exists then show nothing
'else'
Me.cempic.Picture = Me.combined_image_path

any ideas of what this procedure should be??

thanks

Simple Form Totalling Error

Sep 2, 2005

I am making a simple tabular form to use as a subform in another.

The form has a cbo box (cboItem_Name)
Quantity (txtQuantity)
Price (txtItem_Cost)
Extended Price (txtExtended_Price)

Selecting an item in the combo puts the price in txtItem_Cost. Default for Quantity is 1. Control Source for txtExtended_Price = [txtQuantity]*[txtItem_Cost] and gives me my extended price.

I have a control in the footer of the form called txtSub_Total. It's Control Source =SUM([txtExtended_Price]).
This Sub Total box generates the #error.

Can anyone tell me why? Do I need to do some other magic with my txtExtended_Price control instead of a simple calculation, like I have?

Thanks for any help you can give a novice.

Hi,
I get this error when trying to rung a piece of code:
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.

I have the EXACT same code working on other forms using different fields and I just can't figure out why this particular one isn't working, it's driving me nuts!
My code is this:
Private Sub Form_Load()
Dim strReason As String

strReason2 = Nz(Ref3Poor_Reason, " ")

Select Case strReason3
Case "Not Known", "Unwilling to Give"
Poor1NavRef3.Visible = False
Poor2NavRef3.Visible = True

Case Else
Poor2NavRef3.Visible = False
Poor1NavRef3.Visible = True

End Select

Dim Ref3PoorCheck As Boolean
Ref3PoorCheck = Ref3Poor_Reference

Select Case Ref3PoorCheck

Case "True"
Ref3Poor_Reason.Visible = True

Case "False"
Ref3Poor_Reason.Visible = False

End Select

End Sub

Can anybody tell me where I'm going wrong please?

Modules & VBA :: Code Runs OK Once But Error Next Time

Jun 26, 2015

The task is (1) output an Access query to Excel (2) overwrite that file if it already exists (3) apply specific formatting to the header row and the other rows in Excel. I have cobbled the code together from two sources. The beginning and end are adapted from code on btabdevelopment.com but the large insert in the middle is code I got form a project a former colleague had done. But he's no longer around.

The problem: I click the button and everything works OK. The file is created and formatted just how I want. If I click the button a second time though, it seems to run OK, but when I open the file it is NOT formatted. However, theres another window behind it called Book 1 which has all the data and all the correct formatting it just hasnt been saved. If I click it a third time I get an error message that says Object variable or With block variable not set. Im not even 100% all that is accurate because I have tried it a multitude of ways, closing and re-opening the form, closing and re-opening Access itself, starting with Excel open or closed, never with the destination excel file open though. I dont seem to get exactly the same behaviour any two times. But as far as I can see, if I close and re-open Access, it always works the first time. So I can live with it.

Code:
Private Sub cmdExport_Click()
On Error GoTo Errhandler
Dim rs As DAO.Recordset
Dim oExcel As Object
Dim oBook As Object
Dim oSheet As Object
