"Error in loading DLL", VB6 ActiveX DLL

[Scott]

If anyone can help me, I will be very appreciative.

I've written an ActiveX DLL that has mysteriously stopped working on my
development machine but works fine on another test machine. Each machine has
the same version of Excel (i.e. 2003) and is running the same dll and xls
file. However, on the development machine, the code will execute in debug
mode without errors (reference made to vbp file vs dll). I have tried a lot
of things to resolve the issue: OS LiveUpdate, Office Update, delete dll from
registry, register / unregister dll via regsvr32, checked dll using
Dependency Walker, etc but nothing has helped. Ideas anyone? Thanks!

Maybe it's a stupid question, but is your dll located in the SYSTEM32
folder?

 

[Scott]

No, it isn't but I just put it there and changed the reference.
Unfortunately, I received the same result. Thanks for the idea.

Scott,
By "the code will execute in debug mode without errors", you mean in the VB6
IDE ?
And in Excel, you set a reference to the DLL ?
Instantiate the object ?

A bit more info the error/not working may help us.

Scott,
This works for me, which is the same as your code:

'<cXLTest Class module in Test.DLL>
'Reference set to Excel
Dim XLApp As Excel.Application

Public Property Set ExcelApp(vData As Excel.Application)
Set XLApp = vData
MsgBox "Excel set"
End Property

'<Code in Excel WS>
'Reference set to Test.DLL
Dim NewObj As Test.cXLTest

Private Sub CommandButton1_Click()
Set NewObj = New Test.cXLTest
Set NewObj.ExcelApp = Application

Set NewObj.ExcelApp = Nothing
Set NewObj = Nothing
End Sub

But from the error you get, it seems that error is not related to this, as
the dll is not loaded properly.
What about code in Initialise and/oe Sub Main routine ?
