void SendKeypress(CString strText)
{
int len, i;
char c;
len = strText.GetLength();
for (i = 0; i < len; i++) {
c = strText[i];
WORD vkey = VkKeyScan(c);
WORD shift = HIBYTE(vkey);
BYTE scan = MapVirtualKey(vkey, 0);
if (shift) {
keybd_event(VK_SHIFT, MapVirtualKey(VK_SHIFT,0), 0, 0);
}
keybd_event(vkey, scan, 0, 0);
keybd_event(vkey, scan, KEYEVENTF_KEYUP, 0);
if (shift) {
keybd_event(VK_SHIFT, MapVirtualKey(VK_SHIFT,0), KEYEVENTF_KEYUP, 0);
}
}
// Press "Enter"
keybd_event(VK_RETURN, 0x1c, 0 , 0);
keybd_event(VK_RETURN, 0x9c, KEYEVENTF_KEYUP, 0);
