labview hex 0x5EC

[willowsword]

Windows XP machine, service pack 3, LabVIEW 2009

LabVIEW: (Hex 0x5EC) The method in the DLL overwrote past the end of space allocated for one of its parameters. This may have corrupted memory.

Any suggestions?

Check your calling convention to makes sure you are using teh correct type.

Sorry for the brief post, but if there was a general answer there was no need of going into detail. The dll is from hytekautomation for ptp cameras, and I figured I might be able to figure out enough to not have to contact them.  Because this is 3rd party software, I'm assuming that is my next step.  But in case someone else who has a copy of this knows more than I, here are the answers I have...

The code calls a library function, PTPCam.dll, function name Transfer Picture, calling convention C, function prototype void  TransferPicture(int32_t ImageRef, const CStr fileName, int32_t Format, int32_t delete);.

As usual, Ben has probably got it right, you just have to work out where he is right.

I suggest you search on "Rolf" and "dll" and maybe throw in "pointer" to see what the the EXPERT has already said on this subject.

I have never run into a dll calling issue for which Rolf has not already posted the answer.

Co-worker speaking about me in the office : "That Ben is an encyclopeadia!"

My reply on hearing above : "No, at best I am an index."

Thanks so much.  And, lacking a context search, a good index is the next best thing.  Just mucking about, it seems that I was having issues with file format types and file path length, the second of which I suspect was causing this error.  They have it permitted to be 256-10 characters long, but it seems that the function wants it a lot shorter than that.
