    GetWindowText() not working with Vista???

    Hi,
    I've been using the function GetWindowText() for a while now on Windows XP. When I upgraded to Vista Ultimate 64-bit, I started getting different output from the function. Instead of saving all the text, it only saves the first character.

    After hours of trial and error, I decided to try the same code I was using under Vista (and was compiled using VC++ 2008) on Windows XP again, and it worked fine!

    Has anyone heard of such a problem or how to fix it?

    Have you tried compiling under 64-bit Vista?

    yes. I'm compiling using MSVC++ 2008 on Vista. I installed it off the DVD and made sure it installed all the required 64-bit features. But I'm not sure I'm compiling FOR 64-bit, because my profile is still Debug (Win32)...

    32- or 64-bit shouldn't make any difference, but if you are reading back a Unicode string where you expect to get a ANSI string, then you will get the first character (because european/ASCII characters are using the first 256 characters, so the second half of a 16-bit character is '\0' when read as two 8-bit characters).

    Yes I think that is the problem. When I put the mouse on the function in MSVC++ 2008, I get the following popup under the mouse:
    Code:
    #define GetWindowText GetWindowTextW
    so do I just need to remove - or disable - that definition???

    If you want to disable unicode and use ANSI throughout your program, put some #undef UNICODE or something before including other headers.

    If you only want to use that function as ANSI then simply call GetWindowTextA().

    That's more like a hack. What you really want is to go into project settings and set character set to multi-byte.
