cerdisp.c can't synthesizes all keystroke?

Hi

I need a remote display , which in the
directory:\WINCE420\PUBLIC\COMMON\OAK\DRIVERS\CERDISP\CERDISP. I want to use
the
remote contol device keyboard same as keyboard on the local device. for this
i used the cerhost.exe in the pc,and open a
wordPad file in wince device.I am able to successfully move the
right,left,up,down,delete,page up,page down,home,enter in the opened
file just as i do in pc,but i can't insert any other char and i am sure the
wordpad file has the focus.the following code is some of
cerdisp.c
case WM_SYSKEYUP:
case WM_SYSKEYDOWN:
if (recv (Sock, (char *)MouseData, sizeof(USHORT), 0) == sizeof(USHORT)) {
dwFlags = ((WM_KEYUP == Cmd) || (WM_SYSKEYUP == Cmd)) ? KEYEVENTF_KEYUP : 0;
// No scancode data.
RETAILMSG(1,(TEXT("%x,newdwFlags=%d\r\n"),MouseData[0],dwFlags));
keybd_event ((BYTE)MouseData[0], 0, dwFlags, 0);
}
break;


I am able to successfully capture the keyboard event and display with
UART,all Virtual key are right,but the system just deal the
right,left,up,down,delele,page up,page down,home,enter and tab.

Question:
1. which function will be called in the kernel by keybd_event?
2.how can i synthesizes all keystroke?

1. which function will be called in the kernel by keybd_event?
That is actually handled in your keyboard driver.

You could try using Remote Spy to see what windows events are being sent to
WordPad.

It works fine for me. My guess is that you don't have a keyboard driver
installed on the device. Maybe you don't have a keyboard attached, so it's
not loaded or something. The keyboard driver is responsible for translating
the key code information into actual messages with the correct characters.

remote pc,am i need a keyboard driver?
good luck

As I said earlier, keybd_event() is handled by the keyboard driver, so yes.
You can use one of the NOP (Stub) keyboard drivers.
