Hi Pradeep,

It sounds like you are wanting to statically link to your DLL. In that case, the project that is calling your DLL needs to have the header file and the import library file (.lib) included.  Check out another post here that I replied to describing your options of linking to DLLs in CVI. It points to several tutorials and knowledgebases as well.

Best Regards,

Pradeep,

Aside from the issue of the calling convention (which we already addressed), you should be okay with your new version of the DLL.

Pradeep,

There is a great example that shows our users how to create and then use DLLs in LabWindows/CVI.  This is probably the best place to start!

If you are using LabWindows/CVI 8.5, this example is found at C:\Documents and Settings\All Users\Documents\National Instruments\CVI85\samples\dll\basic.

If you are using a previous version of LabWindows/CVI, you can find the example on disk at C:\Program Files\National Instruments\<Your CVI Version>\samples\dll\basic.

Make sure you read the readme.txt file to get started!  The example is well commented and should show you exactly how to create and use a DLL and *.lib file.
