Gpib usb vc++

[I dont know]

I have bought a new USB-GPIB controller. It works well, when communicating with listening instruments by your software-Measurement and Automation. However, when we try to use Visual C net to compile your example (4882query.c), after include ni488.h, it gives out the error information:

Error LNK2020: Unresolved token (ibsta).

Error LNK2020: Unresolved token(ibcntl).

Error LNK2020: Unresolved token(iberr).

3 unresolved externals

Please help me.

Hi I dont know,

What version of Visual Studio/Measurment Studio are you using. 

The USB device will operate in the same way as a PCI GPIB card.

Hi "I Dont Know"

I have compiled 4882query.c using Visual Studio 2005 and Measurement Studio.

I created a Win32 Project and under Visual C++ and  deselected "Precompiled header"

I then removed the files that were added by the wizard from the solution viewer. and added 4882query.c to the source files section.
I then added ni488.h to the header files section and added gpib-32.obj to the resource files section

I was then able to compile the program and get the identity of the instrument connected to my GPIB-USB-B

Hi,

I have tried to do the same for the query example program compilation, but still have the linker problem.

I use Visual Studio 9.0 Express, is it compatible with the program ?
