daqmx with measStud in dll

[mael15]

hi,

i have written a dll that is supposed to handle all the datat aquisition for my gui app.

now when i start the app without any hint of measStud in the dll, everything runs fine. only if i add the line

CNiDAQmxTask* m_task = new CNiDAQmxTask();

 in the dll, my app will not even start. the vs2008 debugger shows no error messange at all. dependency walker shows me two missing dlls when profiling: mxsout_logger.dll and mxsout_profiler.dll. these are national instruments dlls.

what is the problem here?!?

how can i use a measurement studio dll in a non-mfc app?

thanx!!

Hi,

if you anyway want to work without MFC, why don´t you use the DAQmx C API?

You can find the examples somewhere like

C:\Dokumente und Einstellungen\All Users\Dokumente\National Instruments\NI-DAQ\Examples\DAQmx ANSI C

Hi,

I have exactly the same problem. I try to use  C and C++ libraries but it doesn't work.

My programming code is a DLL project using MFC in a shared DLL in Visual Studio 2005.

I'm using it like this:

 Cpp:

CNiDAQmxTask* myTask = new CNiDAQmxTask();

 

 C:      

DAQmxErrChk (DAQmxCreateTask("",&task));

 

But both pauses the program with no event. (No error or breakpoint or anything) The program is not stopped, it's just paused...

Regards,

Nicolas
