It's because the function's signature will treat the pointer argument as a const and not change it. On the other hand, if you had a function that was expecting a LPTSTR and you were passing it a const pointer, then casting would be an issue. "Old age is like a bank account.

I have the same trouble too.

Ok I managed to narrow it down. You where right about .exe it works fine. BUT in case of a dll run by rundll32.exe things change and GetProcAddress returns always wrong

It's because the different conventions place the requirement of cleaning parameters off the stack on different entities. See this Wikipedia entry[^] - WINAPI implies stdcall (callee clean-up), so the caller needs to be told how much stack the called function will clean up - that's what the '@8' at the end of the ServiceMain symbol indicates. Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

By the way, when you get a crash like this, then you can look at the memory dump in WinDbg. The crash dump will either be called memory.dmp in the windows dir or it'll be in the minidump dir dependig on how your machine is set up. The best way to fix bugs though is kernel debuging. Take alook in the DDK for how to do this. (Null modem cable, modify boot.ini, and use windbg) Morality is indistinguishable from social proscription
