Error 6210 using TDMS C DLL

Question

Hi,
I am trying to read a TDMS file using TDMS C DLL in visual studio 2012. I am getting the following error message. Error 6210 : The file passed to library is read only and cannot be modified, when I try to open the file using DDC_Openfile.The program I used is TDMSTesting.zip downloaded from this link
http://forums.ni.com/t5/LabWindows-CVI/TDMS-DLL/td-p/792269
 The sample code given in the Zip file is properly running with the testtdms.tdms available in the file but I am getting the error 6210 with any other tdms files generated from labview.
It would be of great help if anyone could help me to resolve this and I have attached the sample tdms file which I used to run the code.
Thank you
Padma Priya

If you want to export to tdms
pszFileName = "C:\out.tdms"
use "TDMS" as file type.
If you want to export TDM
pszFileName = "C:\out.tdm"
use "TDM".
If you are looking for a simple way to export to tdm
http://zone.ni.com/devzone/cda/tut/p/id/2824
may be a solution for you. It has the capability to
write a tdm header to an existing binary file given in
a specified format (one header/one dll but TDM export only).
P.S.: What error code did you get?
  Did a logfile appear?
  What do you mean by DIAdem error?
