int Fake Keystroke (int key Code Purpose Simulates a keystroke by posting a keystroke event to the currently active panel. This function has the same effect as actually pressing a key at the keyboard. Note The order in which you receive the keystroke event in relation to other events is not defined, so you must use Fake Keystroke with care. Note If you want to send a fake keystroke consisting of a dual-byte character, you must call this function twice. First you must pass it the lead byte of the dual-byte character, in place of the ASCII character; then you must pass it the trail byte, also in place of the ASCII character. You cannot use a virtual key code on either call. Parameters Input Name Type Description key Code int Form key codes by a logical OR operation on values representing a modifier key and either an ASCII character or a virtual key. A modifier key is a < Shift> key, < Alt> key, or menu modifier key (the < Ctrl> key). The following constants represent the modifier key. VAL_ SHIFT_ MODIFIER = 0x010000 VAL_ UNDERLINE_ MODIFIER = 0x020000 VAL_ MENUKEY_ MODIFIER = 0x040000 VAL_ SHIFT_ AND_ MENUKEY = 0x050000 ASCII characters can be represented by a literal character, for example, ' A' or ' D or an ASCII value. There is no distinction between upper and lower case ASCII characters. Virtual keys are non- ASCII keys represented by the following key codes: VAL_ FWD_ DELETE_ VKEY = 0x0100 VAL_ BACKSPACE_ VKEY = 0x0200 VAL_ ESC_ VKEY = 0x0300 VAL_ TAB_ VKEY = 0x0400 VAL_ ENTER_ VKEY = 0x0500 VAL_ UP_ ARROW_ VKEY = 0x0600 VAL_ DOWN_ ARROW_ VKEY = 0x0700 VAL_ LEFT_ ARROW_ VKEY = 0x0800 VAL_ RIGHT_ ARROW_ VKEY = 0x0900 VAL_ INSERT_ VKEY = 0x0 A00 VAL_ HOME_ VKEY = 0x0 B00 VAL_ END_ VKEY = 0x0 C00 VAL_ PAGE_ UP_ VKEY = 0x0 D00 VAL_ PAGE_ DOWN_ VKEY = 0x0 E00 VAL_ F1_ VKEY = 0x0 F00 VAL_ F2_ VKEY = 0x1000 VAL_ F3_ VKEY = 0x1100 VAL_ F4_ VKEY = 0x1200 VAL_ F5_ VKEY = 0x1300 VAL_ F6_ VKEY = 0x1400 VAL_ F7_ VKEY = 0x1500 VAL_ F8_ VKEY =.
I tried your code as it was. I am not sure what you mean by nothing happens When I used the code as it is (except I had to use port 2) everything worked well. the character count was 18 out of the Com Wrt function. Make sure the com port you are trying to use is available. with the exception of your includes, here is your code with minor mods that I ran on my PC, Win XP running CVI 2010: define PORT 2 define PORTNAME COM2 int configure Port(void int send Command(void int port_open; int error; int main configure Port send Command return 0; int configure Port port_open = 0; error = Open Com Config ( PORT, PORTNAME,115200,0,8,1,0, -1 if (error) printf( Error! if (error = 0) port_open = 1; Set XMode ( PORT, 0 Set CTSMode ( PORT, 0 Set Com Time ( PORT, 0 return 0; int send Command char buffer Write[100] ; Fmt(buffer Write, %s, ATD ; error = Com Wrt( PORT, buffer Write, sizeof( ATD ; return 0;.
