Calling ActiveX dll from c
Posted on 2000-04-24
Hi i posted a question earlier and this is basically what i need help with
I need to connect to a vb ActiveX.dll. I have 2 functions in this dll
1) Getsignature(lngAcc as long,lngAmt as long,strTrans as string)
2) FetchSignature(strAction as string,strResults as string)
I need to modify an existing c program so i can initiate a thread to activate this dll and it's first function getsignature.
now the way i understand this is that this thread will run under my C's process space therefore i do not have to worry about
marshaling the threads, is this correct ?
I do know i have to use the Iunknown interface
and the CoCreateInstance, Coinitialise and CoUnInitialise
then i need to call function 2 FetchSignatures()
does anyone have an idea on how to code this in C. My c is very rusty so as much explanation will be appreciated.
I only have the Visual C++ enviroment on the pc, but i do know that u can open a c/c++ source file and put straight c int there ??
thanx allot for your help
