communication between Labwindows and vb

[tupai]

I want to transfer data(an integar value) from Labwindows to visual basic.

Please tell me the ways to fulfill this requirement.

You could use a named pipe, shared memory, or some other IPC mechanism.  Bear in mind that VB doesn't have an unsigned integer type.

Or, you could build your CVI code as a DLL and call the DLL from VB.  You can add a type library to the DLL to enhance VB support.  When you have the type library, the CVI DLL can be loaded as a resource in the VB environment.  Then use an accessor method from VB to get your int value.

You might also wish to use the Shared Variable Library (if you have a more recent version of LabWindows), in which case you could include a LabWindows client DLL for use from your Visual Basic program.
