How to call the DLL writing in Vb6.0 from testsatnd?

[Ivan Chen]

Hi,

I want to call a dll writting in VB6.0 from teststand. But as i see from the "Step Setting" in teststand, only the C/C++ Dll can be selected in the "adapter" type. I try to use this one as my adapter to call my VB6.0 dll, in result, there is no function can be seen in the "function" tab in teststand.Anyone know how to call the DLL writing in Vb6.0?

Hi Ivan,

Just to be sure that your DLL is not wrong

you have check if all functions are well and present.

There is  tool called "Dependency Walker"   You can download it at http://dependencywalker.com/ .

With it you can look "inside" your dll

If you will see your functions there, you will see them (in my case !!always!!) in TestStand, too.

Hope this helps

Hi j_dodek,

How to call the Vb's DLL in teststand?is it the same as calling the C/C++ dll?

[j_dodek]

If it is a DLL you can use the C/C++ Adapter.

have you tried the link. ?

Does it show your functions ?

if not the error is somewhere in your Dll.

if present, may be the blue ones have some idea

Here is some examples using VB6 and TS4.1. They may help.

Hi Ray,

Good link !

I am courious if we talking about an ActiveX Server DLL. It makes sense...

Probably, in which case the ActiveX/Com Adapter should be used not the DLL adapter. The examples I linked to use a VB6 EXE as an ActiveX server.

Yes, you should use the ActiveX adapter.

thanks for you guys kindly reply.

I successfully call my DLL now. it need to use the ActiveX adapter and the dll need to be registered with the command:" regsvr32 "[path]\NameOfFile.extension" before using it.
