Analytics Software

I am trying to utilize Hyperion Enterprise 6.3 API to connect to file based application and extract data.

I have not had much success with it. I am using 'C/C++' apis and calling EntOpenApplication() to connection to the application after I call CoInitializeEx (as suggested in the API documentation)
but I get a dialog with the following message:

No MODAPPDLL parm: OpenApp error

Based on what I could gather from the documentation of Enterprise 6.3 the following should be in the application.ini file MODAPPDLL="HEFILE"
I have checked to see that value is correct.

I am sure that somebody has been able to use the API to connect to Hyperion Enterprise, if you could share your knowledge on this it would be of great help.

I have not been able to find the right resources with regards to code samples on how to use the API. If anyone has knowledge of this, it would be great if you can pass it on to me.

I have installed Hyperion Enterprise 6.3 on Win7 (64 bit), I have been able to create a file based application and log in successfully through Hyperion Enterprise application but not able to log in when I use C/C++ API.
I am using Visual Studio 2008 to create a C++ application that will connect to Hyperion application.

Any help/pointers in this regard is greatly appreciated.
Thanks
