crc.dll

[clear]

Hi,

I had tried to develop a dll with crc code there at Visual C++ 6.0, I got a dll and tried to load at Labview 7.0, but this dosen't work out.

What I do wrong?

If someone know how to do it, please, send me a e-mail to nadja.bressan@fc.up.pt.

Thank you.

The source is attached.

Hi,

When you try to load it in LabVIEW, you have an error message or you dll will not work ?

When you load this dll by a C++ application, have you the same problem ?

Lots of unknowns here.

1) What is the default calling convention you use in your project settings? Visual C uses cdecl here by default and you should make sure you set the Calling Convention in the Call Library Node to whatever you chose there.

2) How does the VI look you are trying to call this DLL function with? Basically your funtion seems to return an uInt16 and takes a pointer to a byte array or string and the length of the buffer this pointer is pointing at as an uInt32.

3) what sort of errors do you get? Crash, error message, nothing at all?

In that case and since you have started the thread it would be nice if you could do some sort of explanation what was the problem and how you solved it, for the reference of others trying to do similar things. Personally I feel it would be at least a nice gesture in giving back some of the effort other peoples have spent to give you possible solutions and insights.

Hi,

After somemany weeks working at the same project we crashed....so if you pay attention at the code you can see that miss a RETURN....a simple one! It's a simple thing that makes the code dosen't work.
