Hello,
I'm trying to build a new dll using daqmx.
When I use examples creating an exe everything works fine. But when I copy the source to a DLL the code won't be executed.
I'm using
MSVC 6.0
DAQmx 8.6
Using MFC
example code: (I got this out of a forum entry)
#include <NIDAQmx.h>
#pragma comment( lib, "NIDAQmx.lib" )
...
void CNIDLL::CheckDevice()
{
int buffersize,n=1;
//Buffer size datatypes
int devicetype_buffersize;
int devicesernum_buffersize;
//Device Info variable initialization
char* devicenames= NULL;
int devicesernum;
devicenames=(char*)malloc(buffersize);
//devicenames = (char*)malloc(devicenames, sizeof(char)*buffersize);
//Get the string of devicenames in the computer
//Here the compiler will stop in debug mode
DAQmxGetSystemInfoAttribute(DAQmx_Sys_DevNames,devicenames,buffersize);
DAQmxGetDevProductCategory("Dev1",&infoValue2);
DAQmxGetDevProductType("Dev1", &s[0], 512);
}
Maybe I've to include something?
Regards
Helmut
