Hello,
It looks like you are missing the GPIB library in your project. I don't remember the name of the file, and I cannot find the example you are using, but the readme file of the example should indicate which library you need to use. Make sure you include the .lib file in your project for your dll.

Which example are you talking about? There is not an example called 4882MFC that ships with Measurement Studio for Visual C++. Anyway, if you're using the Measurement Studio for Visual C++ libraries, this error would be because you're not linking to Ni4882.lib (Ni4882D.lib for debug, or Ni488270.lib for VC.NET release, or Ni488270D.lib for VC.NET debug). If you're not using the Measurement Studio for Visual C++ libraries, I think this error would be because you're not linking to Gpib-32.obj. Please double-check the libraries that you're linking to and see if the appropriate library is missing.

How can I link the library????
How??? what and where I should to add?

what in case in Measurement studio??
and what i case just VC++???

[jonni]

the exampl is here:

NI Developer Zone > Development Library > Instrument Connectivity > GPIB > Programming > Language Interfaces

http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3ED3C56A4E034080020E74861&p_node=DZ52353&p_source=external

how can I link the library???
in both casess Measurement studio and just Visula c++?

You need to link to the GPIB-32.obj file. If you are using Visual C++ 6, this can be accomplished by going to your project settings (menu Project>>Settings), selecting "All configurations" in the "Settings for:" drop-down box, selecting the "Link" tab, and adding the full path (including the file name) of the GPIB-32.OBJ file on your system to the "Object/Library modules" box.

If you have Measurement Studio, look for the NI4882 component in the table of contents of the online Measurement Studio Reference file for information on an alternate way of programming your 488.2 interface using C++ classes.
