    compile once, compile twice ...error

    I saved my projected and compiled it to test it out. I don't know what happened but my computer almost froze from an infinite loop. I press CTRL+ALT+DEL to end my program and my computer freeezes. I restart go back to my project and change the setscrollpos and getscrollpos to set/getscrollinfo. For the WM_VSCROLL message and fixed the infinite loop, all located in the windowproc. I compile to test. Error! I got errors dealing with strings and char pointers. all my errors are is "cannot convert char[number] to this" The errors are located when createing a window using WNDCLASSEX. It compiled with no errors before why do I get errors now? is this a bug in MSVC++ 6?

    Thanx in advance!

    Post the relevant code and the specific error messages and we'll try to help.

    >> why do I get errors now?
    The source file being compiled most likely changed.

    >> is this a bug in MSVC++ 6?
    Nope.

    this is where I get one of the errors. All of the errors are related to this. If I can fix this then I will be able to fix the others.

    WNDCLASSEX wClass;
    wClass.lpszClassName = "CCodeCTRL0\0";

    and I get this error
    cannot convert from 'char *' to 'const unsigned short *'

    You are using UNICODE Win32 APIs and structures - that means that most all your strings will need to be wide charater strings (wchat_t).
    You can tell the compiler to use wide characters for string literals by putting an L in front of the the openning quote.

    >> wClass.lpszClassName = L"CCodeCTRL0\0"; \\ "\0" not needed btw

    Or, you could not use UNICODE APIs and structures by not defining "_UNICODE" when you compile your application.

    I always assume a bug lies with me and not the compiler. Mainly because it always does.
