Read TDM-files with NI's "TDM C DLL" does not work.

[hw70]

Hi,

this is not really a DASYLab-question, but i don't know where to post this:

I want to read a TDM-file using the TDM C-DLL provided on this NI-page: http://digital.ni.com/public.nsf/allkb/A3663DE39D6A2C5A86257204005C11CA

The sample data file was created with DASYLab 12 (see attachments).

The (attached) code is compiled without any errors in Visual Studio 2010.

When i start the executable an error is displayed (see attached image).

What is the problem?!

Try Diadem...

Reading the TDM file in Diadem works flawless, but this insight does not help me: I am researching ways to use TDM data as input for DASYLab. So, i need to understand why the NI provided source and dll is unable to read a data file, that was created by an NI software... 😉

Haven't had time to run your code, but maybe the first group having no channels might cause the problem.

Yes the reason for the error is the first group having no channel.

I have modified the example to read your tdm file without errors. Please have a look to the attached file.

Danke! Works like a charm.
