Call a dll with an activeX component gives error

[darkxceed]

Hello all,

My program consist of:

- Main program

- DLL's

How it works:

The main program is the interface for the user, this main program call's several dll's

The problem:

The main program runs withought problems, but when it call's a dll, which also call's an activeX component, I get an error.

I then made a executable from the dll which then works ok, no problem.

When I click the retry it runs ok, but when I call it again I get the message again.

The message does allways accur, but still very often

Conclusion:

The error message only comes when I call it as a dll, when the dll is standalone executable no problems occur.

Below you can see how I call the dll:

 

 

Can someone please help me with this problem?

Anyone some ideas?

I just found out that when I run the DLL once then let it untouched for a while then test again it goes very good.

strange...

Hi Bart,

As I search google, i find that this error has something to do with the calling convention.

This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

Maybe you can post some documentation of the dll.

Hello Bas,

I have included the vi which calls de dll(executedll.vi) en the dll in VI form(plugin.vi & plugin.lvproj).

As you can see the dll calls the canconfigurator activex component.

And closes the activex component when done.

This plugin will be called several times in the test enviroment.

gr,
