[HELP] Problem with VC ++ compiler

Hi epvpers i'm not an expert in vc++ but i'm learning trying different things...

Well my problem i get a src of a memory scaner made in C, of course i named the source files "somename.c", this is not my problem the problem is that when i run the script inside vc++ it works perfectly but when i open the exe alone without vc++ an error came up :mad:

Here's an image:

I compile the same src in Codeblocks and it works perfectly don't know what could be i wish some one knows

Here is the SRC for those who are curious...

Why i decide to make it work in vc++ cause then i want to compile the same script in a dll and load a form (it's eassier to make forms in vc++)
