Insert Worksheet change procedure

O

ojv

I get a runtime error in Excel using the following method:

Sub AddEvents()
Dim vbc As VBComponent, pos As Long, body as String

For Each vbc In ActiveWorkbook.VBProject.VBComponents
If vbc.name = Worksheets(1).codeName Then
pos = vbc.CodeModule.CreateEventProc("Change", "Worksheet")
body = wsEvent
vbc.CodeModule.InsertLines pos, body
Exit For
End If
Next
End Sub

What am i doing wrong?
Any help appreciated

Hi ojv.
Probably you forget a reference to:
'Microsoft visual basic for applications extensibility 5.x
as required by Mr. "r".
For further informations, see:

Thx for responding. I already have a reference to the extensibility lib. The
runtime crash occurs after execution of

pos = vbc.CodeModule.CreateEventProc("Change", "Worksheet")

before the statement inserting body text.
I am able to insert a number of different events like workbook events, but
this one fails. I just do not understand why.

There are no error number or description. Excel just tells me it crashed,
needs to shut down, will restore my documents and asks the usual question of
wether I want to send an error report to MS.

I've modified such that parameter body is two lines only. When I run the code
below everything works fine inserting the Workbook_Open event. When i step
through the remaining code it goes past the line

LineNum = .CreateEventProc("Change", "Worksheet")

and I see that

Private Sub Worksheet_Change(ByVal Target As Range)

End Sub

is inserted in the code module for the worksheet, it is also there in the
recovered workbook. VB then halts for 1-2 seconds while at the next line

LineNum = LineNum +1

before it crashes displaying the send error message dialog.

I'm running 2002 SP3.

Sub AddEvents()
Dim VBProj As VBIDE.VBProject
Dim VBComp As VBIDE.VBComponent
Dim CodeMod As VBIDE.CodeModule
Dim LineNum As Long
Dim body As String

Set VBProj = ActiveWorkbook.VBProject
Set VBComp = VBProj.VBComponents("ThisWorkbook")
Set CodeMod = VBComp.CodeModule
body = "Dim i as Integer" & vbCrLf & "i=0"

With CodeMod
LineNum = .CreateEventProc("Open", "Workbook")
LineNum = LineNum + 1
.InsertLines LineNum, body
End With

Set VBComp = VBProj.VBComponents(Worksheets(1).codeName)
Set CodeMod = VBComp.CodeModule

With CodeMod
LineNum = .CreateEventProc("Change", "Worksheet")
LineNum = LineNum + 1
.InsertLines LineNum, body
End With
End Sub

Hi ojv.
I believe you had to insert one instructions in one line. Try:

Sub AddEvents()
Dim VBProj As VBIDE.VBProject
Dim VBComp As VBIDE.VBComponent
Dim CodeMod As VBIDE.CodeModule
Dim LineNum As Long

Set VBProj = ActiveWorkbook.VBProject
Set VBComp = VBProj.VBComponents("ThisWorkbook")
Set CodeMod = VBComp.CodeModule

With CodeMod
LineNum = .CreateEventProc("Open", "Workbook")
LineNum = LineNum + 1
.InsertLines LineNum, "Dim i as Integer"
LineNum = LineNum + 1
.InsertLines LineNum, "i=0"
End With

End Sub
