    keybd_event bug?

    When i try to send two letters using keybd_event:
    Code:
    keybd_event('m', 0, 0, 0);
    keybd_event('m', 0, KEYEVENTF_KEYUP, 0);
    
    keybd_event('n', 0, 0, 0);
    keybd_event('n', 0, KEYEVENTF_KEYUP, 0);
    i get:

    Instead of m, '-'
    Instead of n, '.'

    It send capital letters and numbers fine, but lower-case letters, and symbols dont work at all.

    Here is the list of Virtual-Key Codes.
    Notice that the alpha keyboard keys coorespond to uppercase ascii codes. So 'A' is the A keyboard key, which can be "a" or "A" depending on the state of the shift keys and caps lock key.

    Look at the example for keybd_event() to see how to get keyboard state information.

    so in other words send your kb_events to do this:
    1. Depress Shift key
    2. Depress A key
    3. Release A key
    4. Release Shift key
    If you speak or are learning Spanish, check out this Spanish and English Dictionary, it is a handy online resource.

    Did you completely ignore Codeplug's post?
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    VK_OEM_COMMA (BC)
    Windows 2000/XP: For any country/region, the ',' key
    To me, that only implies that you're garenteed to ge a comma character regarless of the country/region, if its Win2k/XP. Doesn't say anything about it's lack of availability.

    I would try it out.
    Otherwise, you can use VkKeyScan() to get the correct virtual keycode and keyboard state for a character.
