Using a Matlab 7.4 dll in Labview 8.6(Using MSVC6 (sp6))

[RushPica]

Dear all,

I encounter the problem about "using a matlab dll in Labview". 

I refer to the previous discussion and post, 

like as, http://forums.ni.com/ni/board/message?board.id=170&message.id=29793&view=by_da 

It is very useful to me.

Special thanks to "dsavir",

I follow the above documentions to process. 

Nevertheless, i still face the difficulties in compiling in the VC6.0, 

I am not familiar with the Visual C++,

please, give me some suggestion to address this problem

There are lot of syntax error too. Did you try correcting them?

I would say you somehow miss some header. Most if not all errors seem to be caused by the missing of the declaration of the REFCLSID identifier.
