problems with *dll files

[srapp@moog.de]

I have created a *.dll from a*.c file in labwindows and I want to use this as modul in teststand. then when I execute my teststand seq the following error occure:

"could not find function "function name of my function of the *.c file" in the *.dll file". this error message occures although the function is in my *.c file.

is there a problem with converting *.c files in *.dll files in labwindows, or is it another problem?

how can I solve this problem?

Hi,

You need to make sure you have exported your function correctly in you dll.

Did you use something like __declspec(dllexport) as part of you function syntax?

Ray,

no my file doesnt contain a function like like __declspec(dllexport)

what does this function contain?

Hi,

No its not a function.

Your exported function should look something like this (being in mind this is a TS2.0 prototype, the different being the argument of the function eg testData and testError)

void __declspec(dllexport) TX_TEST MyTestFunction(tTestData *testData, tTestError *testError)
