Question

I am having difficulty in calling a thrid party DLL form within Mathematica. My code is:

     qmConnectLocal = 
         LibraryFunctionLoad["C:\\Windows\\QMClient.dll", 
         "QMConnectLocal" , {String}, Bool]

what I get is:

    LibraryFunction::btype: Invalid type and/or rank specification in String. >>

I am too much of a novice in Mathematica code to understand what it is trying to tell me.

Any help?

Answer 1

The documentation says that it has to be "UTF8String" (with quotes) instead of String. So what happens when you try

qmConnectLocal = LibraryFunctionLoad["C:\\Windows\\QMClient.dll", 
 "QMConnectLocal" , {"UTF8String"}, Bool]
