Yep, that was the problem. Thanks!

But like I expected there is still another problem with using sscanf_s.

In Dev-Cpp the following Code worked:

DLLFUNC void string_test()
{
char buffer[50];
short reseiver;

sprintf_s(buffer,50,"%d",10);
sscanf_s(buffer,"%d",&reseiver);
}

But if I use this function in GS i get this runtime error:
Debug Error!

Run-Time Check Failure #2 - Stack around the variable 'reseiver' was corrupted.

What am I doing wrong?

[edit]I found out that this problem only occurs in a dll. If I build the whole thing as console application everything works. Maybe some settings are affecting this.

I uploaded a testproject which should show my problem. There are 2 folders, one with the VC++ 2008 project and one with the C-Script test. Just open test.wdl with SED and than debug->set main to current and then debug->testrun. Than you will notice my problem.
You will need winrar to unpack.

Thanks for your help!

I found out that this problem only occurs, when reseiver is short. With int everything works.
It would be interesting why this doesn't work with short...

Dark_Samurai

you could try adding a __asm pop ax or a __asm push ax after your function, if dev-cpp supports that.

It works now.
By the way I'm using VC++ 2008, not Dev-Cpp now.

And after some testing I found out, that a dll written with VC++ doesn't open correct on some computers. I tested it on 4 different pc and only on one it' was opened. Did somebody already had this problem? What are typical mistakes when this problem occurs? Wrong headers/libraries, wrong project settings?

Dark_Samurai

The users of your dll must have the VC++ 2008 redistributable libraries installed.

Are there any libaries which are already pre-installed on the most systems?
Because I don't want that my end users have to install more than my game it self...

Dark_Samurai

I installed the libraries on the other pcs but it still doesn't work.
If I would use an older Version of VC++ (like 2005), would there also be such a problem? Which Version should I choose?

I think that behavior of microsoft appeared in vs service pack 1.

I'm not really sure, but not using "multithreaded-dll" and instead "multitreaded" in C++/Codegeneration in the compiler options may fix the problem.

Ok I tried that, but with the new settings I get this error:

"mt.exe : general error c101008a: Failed to save the updated manifest to the file ".\Debug\enet.dll.embed.manifest". Wrong parameter."
