>>>Based on what you've given us, I'd say the above declaration is also correct. If I were to hazard a guess as to what the problem is it would be that the declaration of the structure should indicate a pointer to the structure member identified as the char type. That's strictly a guess, but it would explain the invalid parameter message since, in this case the structure itself would only be 32 bytes long.

Had already looked at those, but only at the numtoDWord function in Ed Rauh's Heap Allocation. But it didn't work either. So I took the step and looked at their sample in VB6 (*shiver*) and see what they did there. Turns out that the structure size is 160 bytes (weird in my opinion. 7 DWords, 128 bytes string and one extra DWord as point maybe?). Now it initialize fine.

Again thanks for helping and letting me know that I'm not as crazy as I think.
