Hi,

I want to make some hotkeys for my application. I want to bind the space bar. - but space bar doesn't have an ascii code, it has a virtual key code. Is that virtual key code value consistent for all keyboards? I'm trying something like:

    // VK_SPACE on my machine is defined on 0x20.

    LRESULT ViewBase::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
    {
        switch (message) {
            case 0x20:
                 AfxMessageBox("User pressed space bar.");
                 break;
        }
}

Thanks

I meant VK_SPACE is consistent.
Although you might want to change your WindowProc to

    LRESULT ViewBase::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
    {
        switch (message) {
            case WM_KEYDOWN:
                 if(wParam == VK_SPACE)
                    AfxMessageBox("User pressed space bar.");
                 break;
        }

I think you are wanting to make accelerators. Try editing your accelerator in your resources. Add the keys you want commands for there. Then you can add ON_COMMAND handlers for those in your view.
