Customising multiple error messages for a command button

[Ezzz]

I have customised a form to display my own error messages using:-

Private Sub Form_Error(Data Err As Integer, Response As Integer)
' If an error occurs because of duplicate data in a required field
' Display own custom error message

Const conErrDuplicate Key = 3022
Const conErrZeroKey = 3058

Select Case DataErr
Case conErrDuplicate Key
MsgBox "This Serial Number already exsists: " & Search, , "Warning Duplicate Record!"
Response = acDataErrContin ue

Case conErrZeroKey
MsgBox "You Must Enter a Serial Number before you Save the Record: " & Search, , "Warning No Serial Number!"
Response = acDataErrContin ue

Case Else

'Display a standard error message
Response = acDataErrDispla y
End Select

End Sub

In order to get my "Save" command button (not changed from Command26) to do the same i used:-
Private Sub Command26_Click ()
On Error GoTo Err_Command26_C lick

DoCmd.DoMenuIte m acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70

Me.[Serial Number].SetFocus
Me.Command26.Vi sible = False

Exit_Command26_ Click:
Exit Sub

Err_Command26_C lick:

If Err = 3022 Then
MsgBox "This Serial Number already exsists: " & mSearch, , "Warning Duplicate Record!"

Else
' Display the error number and the generic Access message.
MsgBox "Error #: " & Err.Number & " " & Err.Description

End If
Resume Exit_Command26_ Click

End Sub

But this only works for the one error code. Is there a way to get my "Save" command button to work with multiple error codes like my form?
PS. my programming skills are very basic at best, the above has been copied and adapted from info found on the net.

When you save the record, the Form's Before_Update event is automatically called, and you can use it to check for other errors, give a message, and cancel if necessary. If you set Cancel to True, you should get an error from the save record event. Here is an example straight from one of my projects.

Private Sub cmdSave_Click()
On Error GoTo ErrorHandler

    RunCommand acCmdSaveRecord
            
    If CurrentProject.AllForms("frmViewProjects").IsLoaded Then
        Forms![frmViewProjects].Refresh
        Forms![frmViewProjects].Form_Current
        Forms![frmViewProjects].Update
    End If
                
    DoCmd.Close acForm, "frmEditActivity"
    
ExitCode:
    Exit Sub
ErrorHandler:
    If Err.number = 3022 Then
        MsgBox "That activity already exists.", , "Duplicate Activity"
    Else
        HandleError Err.number, Err.Description, Me.Name & "::cmdSave_Click"
    End If
    Resume ExitCode
End Sub


Private Sub Form_BeforeUpdate(Cancel As Integer)
On Error GoTo ErrorHandler
    Dim valid As Boolean
    Dim strCriteria As String
    
    valid = True

    If IsNull(txtActivityNumber) Or txtActivityNumber = "" Then
        txtActivityNumber.BorderColor = 255
        valid = False
    Else
        txtActivityNumber.BorderColor = 11050647
    End If
    If IsNull(txtActivityTitle) Or txtActivityTitle = "" Then
        txtActivityTitle.BorderColor = 255
        valid = False
    ElseIf InStr(txtActivityTitle, """") > 0 Or InStr(txtActivityTitle, ";") Then
        MsgBox "Please avoid "" or ; characters for database compatability.", , "Input Error"
        txtActivityTitle.BorderColor = 255
        valid = False
    Else
        txtActivityTitle.BorderColor = 11050647
    End If
    If IsNull(cboProjectLeader) Or cboProjectLeader = "" Then
        cboProjectLeader.BorderColor = 255
        valid = False
    Else
        cboProjectLeader.BorderColor = 11050647
    End If
    
    If valid = False Then
        lblError.Visible = True
        Cancel = True
    End If
  
ExitCode:
    Exit Sub
ErrorHandler:
    HandleError Err.number, Err.Description, Me.Name & "::Form_Before_Update"
    Resume ExitCode
End Sub

Thanks for the the above, but addapting it to my form is a bit beyond me?
It also looks like you are coding different entries to your form and i want to code the one entry box [Serial Number] to display multiple error messages.

I did however adapt part of it by adding an End If and then a new If Err statement see highlighted below:-
Private Sub Command26_Click ()
On Error GoTo Err_Command26_C lick


DoCmd.DoMenuIte m acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70

Me.[Serial Number].SetFocus
Me.Command26.Vi sible = False

Exit_Command26_ Click:
Exit Sub

Err_Command26_C lick:

If Err = 3022 Then
MsgBox "This Serial Number already exsists: " & Search, , "Warning Duplicate Record!"

End If

If Err = 3058 Then
MsgBox "You Must Enter a Serial Number before you Save the Record: " & Search, , "Warning No Serial Number!"

Else
' Display the error number and the generic Access message.
MsgBox "Error #: " & Err.Number & " " & Err.Description

End If
Resume Exit_Command26_ Click

End Sub

This almost solves my problem in that it now displayes the error messages i want it to but it also displayes the default error message for 3022 as well. Any ideas??

Please remember to use the code tags [code][/code] around your code. It will make it much easier to read.


What you need is to use either a Select statement:

Select Case Err.Number
  Case 3022
    MsgBox "This Serial Number already exsists: " & Search, , "Warning Duplicate Record!"

  Case 3058 
    MsgBox "You Must Enter a Serial Number before you Save the Record: " & Search, , "Warning No Serial Number!"
   
  Case Else
     'Display the error number and the generic Access message.
     MsgBox "Error #: " & Err.Number & " " & Err.Description

End Select

Another option is to use the elseif statement

If Err.Number= 3022 Then
    MsgBox "This Serial Number already exsists: " & Search, , "Warning Duplicate Record!"

ElseIf Err.Number = 3058 Then
    MsgBox "You Must Enter a Serial Number before you Save the Record: " & Search, , "Warning No Serial Number!"
   
Else
     'Display the error number and the generic Access message.
     MsgBox "Error #: " & Err.Number & " " & Err.Description
End If

A more general suggestion to help yourself, is to give your buttons a sound name.
Some people like to use for command buttons the prefix cmd (example cmd_Save or cmdSave), I myself prefix all my buttons with btn, btn_Save for example.

Thats it the ElseIf statement works a treat many thanks.
