    What compiler are you using?

    Oh, sorry - I'm using code blocks 10.05 with the default GNU GCC compiler.

    If it contains "stdafx.h", it is probably a MSVC project.

    The proper name is stdafx.h. Check if this is correct.
    I never put signature, but I decided to make an exception.

    Yes indeed, my apologies:


    #include "stdafx.h" is the line it chokes on. I copied and pasted it this time.

    You are using Code::Blocks so you do not need to include stdafx.h. This is a Microsoft specific include file. Also gcc, the compiler that Code::Blocks is using may not support the #pragma directives.

    Thanks Jim for your help, Looks like I'm shafted - I'm pretty frustrated right now, I set aside an afternoon to do this tutorial, to be honest I'm bored with making console applications and I want to move on to making GUI type programs - Can you suggest a productive way for me to move in this direction this afternoon/evening?

    btw. The tutorial didn't mention needing any "special" files, and the previous "hello world" example worked OK. I guess I'll have to search for a tutorial that works with code blocks, I know theres templates for win32 apps in codeblocks but I dont understand them so was trying to learn - How annoying, trying to learn a language seems to be more about learning about IDE's and compilers - I thought I read that C++ was portable and was a standardised language?

    After reading your post I 'commented out' each sticking point in turn. In case its of any use to anyone, here's the other lines that the IDE/Compiler stopped at.

    SetTextColor(hDC, COLORREF(0x00FF0000));
    TextOut(hDC,150,150,string,sizeof(string)-1);
    GetStockObject(WHITE_BRUSH);

    Without seeing the code that is causing the problem I can't help much. But the three lines you show should compile correctly, as long as the correct include files are included since they are part of the Windows API. If you post the code causing the problems, or a link to the tutorial in question, along with the complete error messages, exactly as they appear in your development environment. Someone may be able to help.

    Of course it is... but the Windows API isn't.
    As long as you stick to standard C++ and Portable libraries, everything ought to work everywhere...provided you set up the environment correctly .

    Thanks, I'm sure your post is correct, but how does one "stick to standard C++ and Portable libraries & set up the environment correctly"? its a chicken and egg situation for me as I'm trying to get started but spending more time working around IDE/compiler problems than writing/learning code. I didn't take this up (again) because I wanted to be an IT troubleshooter - I just remembered how much fun I had a s a teenager writing BASIC programs and such like... Perhaps C++ is not for me?

    These errors seem to be linker errors. How did you create your project for this program? What type of program did you tell the IDE to create, a console app or a Win32 app?

    The below line is an Visual C++ only line.

    Code:
    #pragma comment(linker, "/subsystem:windows")
    To fix you need to add the linker option for MinGW GCC that matches the above option.

    from Compiling Windows GUI Application With MinGW Without Command Prompt

    The old option was this
    Code:
    -mwindows
    It was replaced in newer version of MinGW GCC with
    Code:
    -Wl,-subsystem,windows
    I suggest finding directions for the same Compiler (MinGW GCC) you are using; the frustrations will be much less. Or, changing to use the Compiler in your directions.

    Jim - you are a star!

    OK, so here's what happened. I started a new win32 project (dialogue based, if that makes any difference) then deleted everything except the main source file. I then deleted all the code and pasted in the code from the tutorial - after that I removed the #pragma comment(linker, "/subsystem:windows") and #include "stdafx.h" lines and it worked.

    Tim. S: I read everythjing in your post and link, but I am not sure that I'm any wiser! Is it something to do with the "make file"? what on earth is that?

    Thanks again. Looks like I did learn something this afternoon, but not what I intended, lets hope I can move forward at my next session!

    Unfortunately, there is no standardized UI for C++, so it will be a little slow to get started since you have to learn all the tricks and solutions people have come up with to make things work.
    Ideally, after this everything will be fine. But C++ can be a tricky language for newbies. If you are still content with this (seeking help a little now and then), then C++ is fine.

    Now, I really suggest you drop the Win32 API tutorial and go download Qt. It's written for C++, it's portable and it's a heck of a lot simpler than the Win32 API (which is a mess).
