Hi, I am trying to read Data from a frame grabber card in my PCIe slot. When I call the "Initialize" function from the .dll I got with the card I always get the error 1097. 1097 means that the function called threw an error. When I run the program that came with the frame grabber, the frame grabber still works. If I simply omit the "initialize" function call and continue with the function, that would be called after the "Initialize" function, LabVIEW crashes(Program shuts down without any warning). I also got a LabVIEW program that uses the dll which was supposed to work. But here I get the same error. Do you have any idea what normally causes this behaviour and how I can solve this Problem?

I second nathans post. Error 1097 is almost always an error in configuring the Call Library Node right. And in some cases there is no right way to configure and you need a wrapper DLL to convert between what the Call Library Node allows and what your DLL requires. The reason that it sometimes works and other times not, is in fact that it never really works, but sometimes the error that gets caused can not be detected by the OS and LabVIEW does not get an according exception. This can change depending on LAbVIEW version, runtime or development system and even recompilation of the code after small seemingly unrelated changes to the application.

Error 1097 calling dll

Solved!

Yeah, that's right.

They still offer one card for the PXI but that doesn't have 4 inputs, so I would have had to buy 4 of them and program them accordingly. As I posted before, I found another grabber. Hopefully that'll do better...
