building a DLL with a reference to activeX EXE

Question

User-748188285 posted

I built my first DLL with Visual Studio 2008 in Basic.

That works OK.

I have added  an activex EXE  as a reference to the project.

Which comes out to be    Interop.myOther.dll

When I get toline

objDLL = New myOther.myClass

The DLL crashes with

"Object reference not set to an instance of an object"

I have tried several things.

What do I need to do to get around this problem?

TIA

Hi, please try the following codes:

Dim objDLL As Interop.myOther.myClass

If the issue persists, please set breakpoints to your codes and check whether you can access “Interop.myOther.myClass” properly.

I do not have that option to set as

" Interop.myOther.myCLass"

So, there is only one option remains. Need to figure out where exactly it gets removed from Application. I would say use some kind of logger to log at different events, whether there is any value for ActiveX Exe or Interop.MyOther.dll of application.
