Link error

[Valy]

I use the functions from external DLL. The Linker always gives me error:

Undefined Symbol _UsbPt104OpenUtitq@8.

UspPt104OpenUnit() is the function that opens the USB port, on them  USB device is connected.

hello Wolfgang,

thanks, I had not included the DLL's   .lib in my LabWindows/CVI project. Edit/Add Files to Projekt.

Now works ok!
