Hi All,
We are facing a critical issue in our application and I need your help in solving this issue:

Currently our application is communicating with Mainframes to get the Statements and we are using AFP2PDF converter to convert the AFP file format from Mainframes to the PDF format. The flow of the application is like :
.Net applicationàstiSocket dll àAFP2PDF dll
(C++ Dll) (C++ Dll)

Existing application in deployed in Windows Server 2003 (32 – bit System) and the stiSocket dll is built for 32 bit and AFP2PDF dll is also built for 32 bit. So there is no problem in the existing application.

Now we are deploying the code in Windows Server 2008 (64 – bit system) and the first problem we faced is the communication between the >net application and the stiSocket.dll. This issue occurs because the 64-bit application tries to call the 32 bit stiSocket.dll. we solved this issue by re-compiling the stiSocket application in a 64 bit system and we changed the setting of the project to work the dll in 64 bit system.
(we had the source code of the stiSocket application).

Then the problem comes when the stiSocket.dll communicates with the AFP2PDF dll. This again occurs when the 64 bit stiSocket dll communicates with the 32 bit version of AFP2PDF dll. We could not able to change the settings for this dll as we don’t have the source code for this dll.

Is there any way to call the 32 bit C++ dll in the 64 version of dll?

Kindly give your comments on this issue.

Thanks
