VK_SHIFT sticks down till i press it manually

okay well im working on something where i need to use VK_SHIFT well ill show u what i have right now...

Code:

---

#include <windows.h>          // Win32 API function support



INT APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE, LPSTR, int nShowCmd)
{
        // TODO: Now we will perform what we want to do
        {
            HWND hParent = FindWindow(NULL, "Untitled - Notepad");  // Find window
            if (hParent)    // Valid window handle?
                {
                    SetForegroundWindow(hParent);    // Show the window
                    SetFocus(hParent);    // Set window focus to new window
                    // Loop through twenty-five
                    for (int l = 0; l < 25; l++)
                        {

              keybd_event(VK_SHIFT, NULL, KEYEVENTF_EXTENDEDKEY, NULL);    // Key down
              keybd_event(0x32, NULL, KEYEVENTF_EXTENDEDKEY, NULL);    // Key down
                        keybd_event(0x32, NULL, KEYEVENTF_KEYUP, NULL);          // Key up
                                                          keybd_event(VK_SHIFT, NULL, KEYEVENTF_KEYUP, NULL);          // Key up
                        }
                }
                else
                        return 0;      // Invalid window handle; exit
        }



        return 0;
}

yeah and that will go to a notepad thingy and type a bunch of @@@@@@@@@ and umm then shift is still being held down like if i type something after the program ends shift is stuck down untill i hit it again and i was wondering how to fix this?

Code:

---

keybd_event(VK_SHIFT, 0, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, NULL);

---

As per the MSDN sample.

huh? i need it to do shift then A then turn shift off but it just keeps shift on forever!

Don't you hate it when people ignore your advice? Do exactly what anonytmouse said:

Code:

---

              keybd_event(VK_SHIFT, NULL, KEYEVENTF_EXTENDEDKEY, NULL);    // Key down
              keybd_event(0x32, NULL, NULL, NULL);    // Key down
                  keybd_event(0x32, NULL, KEYEVENTF_KEYUP, NULL);          // Key up
                  keybd_event(VK_SHIFT, NULL, KEYEVENTF_KEYUP|KEYEVENTF_EXTENDEDKEY, NULL);          // Key up

---

Note: I also removed the extended key flag from the second line, it's not necessary.

I also think it's a good idea to use FindWindow() with the class name rather than the window text:

Code:

---

HWND hParent = FindWindow("Notepad", NULL);  // Find window

---

EDIT: You also don't need to specify extended key for SHIFT, I think that just makes it right shift instead of left shift. So, the following is fine:

Code:

---

keybd_event(VK_SHIFT, NULL, NULL, NULL);
keybd_event(0x32, NULL, NULL, NULL);
keybd_event(0x32, NULL, KEYEVENTF_KEYUP, NULL);
keybd_event(VK_SHIFT, NULL, KEYEVENTF_KEYUP, NULL);
