Problems with IMAQ write file.vi

[Lizzy]

Hi, I am new in the community and I have some issues with a Labview program I got from a colleague. The program is written with in Labview 8.6 and controls a camera (Guppy 160 b/w) and a translation stage. The camera is supposed to take 2 grayscale pictures when the stage is in a certain position. The bmp images are safed using the IMAQ writeFile.vi. For my colleagues setup it worked but I receive the following error message:

 "Error -1074396080 occurred at IMAQ Write File.

Possible Reason(s):

IMAQ Vision: (Hex 0xBFF60450) Invalid Image Type."

and the files that are written are empty.

Furthermore there is no information in the extended Labview help concerning the IMAQ writeFile.vi. I only found IMAQ writeFile 2.vi, but using it I get the same error message as before. I don't know what to do. Can anybody help me? Thank you in advance!

PS: You find a snapshot of the program (with the IMAQ writeFile 2.vi) in the attachement.

I seriously cannot understand the code. Why are you using so many local variables. Though i am one who is not against it but the flow is definetly missing here. What is pos 1, pos 2,pos 3. If the above link is not the case i will suggest you attach the vi instead for us to get  a better idea.

It wasn't me who made the code.:-) But thank you for the link! I figured out the problem. Although me and my colleague were using the same camera minemakes 16bit images and his just 8bit (probably due to a different driver). That's why the VI couldn't safe bmp-files in my application.

Thanks again!
