1) Wrap your code in [ source ] tags for readability
2) What are you building this with? The errors certainly don't look like VS2005's... you may still need to install/download the platform SDK
3) There are many better alternatives to GDI+, and C++ for that matter.
4) unsigned_int32 isn't a built in type, not even as an extension on most compilers that I'm aware of. If you're expecting this to be from some other header, move it *after* that header is included
5) using namespaces before your headers are all included is bad mojo and a nono, typically. You're also using the same namespace twice.

6) More descriptive thread titles will get a better response. :)


I agree. Most anything with abbreviations such as "plz" gets ignored.


Did you write this code or copy and paste it? What IDE are you using?

Also for C++ that code is pretty outdated. #include <stdio.h> is C, #include <iostream> is c++. Not to mention if this is your only code, its missing a main().

It has a WinMain, though.

The compiler error curiously lack line numbers, and convert file names to all caps. I wonder if the OP is using a 16-bit compiler? Either way, it does not appear as if the compiler has been properly informed of the directories to search for include directive resolution.

That and there are various bits of illegal code in there. You're going to have to provide more information, mostaqil cts, as well as more directed questions.

That can't possibly be a C++ compiler, can it?

Isn't "NONAME00.CPP" the default filename for Borland Turbo C++ (the DOS version)? That would explain the lack of support for "using namespace", and of course the missing Win32 headers.

Ok K i didn't have a experience in C++


i will give you the main cod , which i have taken it from wab:

it is about "Edge Detection"

this is the main code, and there are an error with it:

mostaqil cts, what compiler are you using? There is simply no way you will get that code to compile on Turbo C++ for DOS. You can't expect to be able to generate 32-bit Windows object code with a 16-bit MS-DOS compiler, let alone one that was released almost 20 years ago.
