Mouse events couldn't be captured.

invis (6)
Hello all,
I tried to run this code which records Mouse events but it seemed mouse events couldnt be captured on my computer, mouse clicks , scroll wheels, clicks...
Only Keyboard events were captured correctly, sometimes , after I hit Ctrl+F5 to run compiled prog , mouse events shows 1 and that's it.

I use C++ Express, hope you guys could help me.
Thanks.

Please ask me for any information I can provide since I am so desperate now knowing why it doesnt work ..

I think you should call this: SetConsoleMode(hIn,ENABLE_MOUSE_INPUT);
somewhere before the loop

Close, but before the loop, and don't lose other modes:

int main()
{
    ...
    DWORD consoleMode;

    if (!GetConsoleMode( hIn, &consoleMode ))
    {
        // not connected to a console!
    }
    SetConsoleMode( hIn, consoleMode | ENABLE_MOUSE_INPUT );

    while (Continue)
    {
        ...
    }

    SetConsoleMode( hIn, consoleMode );
    return 0;
    }


There is one other thing that MS neglects to warn you about. The "QuickEdit" mode option on your console must not be enabled. Yes, I know... stupid. I don't know how to disable it programmatically. (I'll figure it out someday though --probably long after it is obsolete. :-P )

To find out, choose "Properties" from the console's system menu (right-click the icon on the console titlebar) and examine the lower-right side of the "Options" tab.

As long as QuickEdit mode is enabled, your console applications will not receive mouse events. Alas.

Hope this helps.
