Author Including VB dlls in Clarion code
James O Brien

2005-01-11, 3:55 pm

Hello,
I am just curious, is it possible to include Visual Basic dlls within
clarion. I have seen someone do this with c++ dlls etc.

Basically I wrote a little program in vb to do some database work that
Clarion was not able to do. I wish to call a few methods in this dll,
from within my clarion code. Is this possible???

I am trying to include the .lib file within my library objects but am
getting the error message

Error(6): cif$fileclose The Handle is invalid

Any ideas on what this means??
Thanks,
James

As it stands out of the box, VB can only produce COM DLLs
So you either need to write CW code to create the object and call the
method, or you need a 3rd party VB add-on that'll let you create regular
DLLs which you can call from CW

I've done it the 2nd way, although not recently
