But as I said earlier, you don't need any of that. You need to CALL the Get & SetConsoleCursorInfo, not declaret the prototye.

Note that the DevC++ environment may well come with windows.h files that are modified or use extra includes to "fix up" any Microsoft compiler dependancies that are in the Windows.h file from MS.

I put these

Code:

SetConsoleCursorInfo(0, 0);
    GetConsoleCursorInfo(0, 0);

is it right? it's still doesn't work..

thanks for your reply..

No, you can't just pass in zero's to this function - or at least, that won't hide the cursor.

You probably need something like this:

Code:

bool hideCursor(void)
{
    HANDLE hOut;
    CONSOLE_CURSOR_INFO cursInfo;

    hOut = GetStdHandle(STD_OUTPUT_HANDLE);
    if (hOut == INVALID_HANDLE_VALUE) {
       return false;
    }
    if (!GetConsoleCursorInfo(hOut, &cursInfo)) {
       return false;
    }
    cursInfo.bVisible = 0;
    if (!SetConsoleCursorInfo(hOut, &cursInfo) {
        // Error can't set cursor info.
       return false;
    }
}

I currently haven't got a setup to check if it works, but it should give you an idea of how it should be done. I'll leave it to you to implement "uhhideCursor".

wow.. I haven't learnt bool yet..

I just pasted it and got errors

Code:

 In function `bool hideCursor()': 
121 koper.cpp expected `)' before '{' token 
125 koper.cpp expected primary-expression before '}' token 
125 koper.cpp expected `;' before '}' token

121 to 125

Code:

    if (!SetConsoleCursorInfo(hOut, &cursInfo) {
        // Error can't set cursor info.
       return false;
    }
}

I wonder why it's error because GetConsoleCursorInfo doesn't error..

There probably needs to be a "return true;" at the end of the function too.

Then you should be learning the language first.
