Default Problem with Common Dialog in Corel VBA

Here is a trivial snippet of code that runs happily on my computer, and some client computers, but not on others.

=========================
Sub UploadAnalyzer()
Dim dlgBrowse As CommonDialog
Dim myDoc As Document
Dim myRefText As Shape
Dim myRefText2 As Shape

Set dlgBrowse = New CommonDialog


<-snip->

The error occurs on the " Set dlgBrowse = New CommonDialog" statement. The error is "Run-Time Error '429' ActiveX component can't create object."
All my references appear to be correctly set in the project, and the comdlg32.ocx is registered as far as I can tell.

As a test, I created a VB app that does nothing but open the common dialog 'Open' window and installed it on a mis-behaving computer. The dialog opened correctly from my VB app, so the OCX is working ok.

Any Ideas?

Oops I should have noted that we are running Corel11.

How did you "install" your test VB application? Could it be that while you install it, the common dialog OCX is also installed? As far as I know, things like Common control and common dialog libraries are not part of standard install. They do come standard with stand-alone VB and Visual Studio but you can't rely on them being on user machine.

When you go to Tools>References or Toolbox>Custom controls, which library for common dialogs are you referencing? Is it the same version as in your test VB application?

Default Solution Found

It turns out that the Common Dialog is a licensed product! My development machine has a license on it, but this particular client machine did not. I am suprised that I hadn't encountered this problem before.

The workaround-

instead of

set myDLG = New CommonDialog
with mydlg
.showopen
.
.
.



I embedded a common dialog control onto a form defined just for this purpose.
so my code now looks like
with frmDialog.Commondialog1
.showopen
.
.
.
.
....
This change is enough to make VBA happy to invoke this control. Pretty simple to fix, but frustrating to uncover.
