used external dll with labwindows CVI

[Mg35]

Hi,

I'am beginner labwindows (version5.1 under W98).
I use a PC card Axiomtek DASP52032 with 16 Inputs-16 outputs.
it's include example programs for  Delphi, Bcb, Mfc et VB et not CVI
On the Cd,  I find  file  DASP52032r.dll and  files .lib - .h for Bcb et Mfc
but when I compile the error is  :

Abort load of librairy ......
when  I add to project the lib of   directory Borland Bcb

or

Bad header encountered while reading external module
Aborted load of member
Aborted load of library
when I add to project the lib of   directory microsot mfc

Thank's  for your answer to help me.

Michel


join  .h file where I replace
EXPORT  by  __declspec (dllimport)

I am not sure if CVI 5.x supports creating a lib file like mentioned here, Michel.
Using a lib file created by CVI might solve your issue.

Michel, I forgot to mention:
If you do not succeed in creating a lib file for that DLL: You can use explicit linking
As a result, you do not need a lib file but your C code must call GetProcAddress() for each DLL function that you want to use. See the link to Microsoft's MSDN.
