EVENT_KEYPRESS Trigger.

[NI Nubie]

I have a text string control that I use to enter text and then when I press the <Enter> the text is sent out an RS232 comm port.

Is there a way to sent each character immediately after it is entered into the text window instead of waiting for the <Enter> key?

I want to emulate an RS232 comm port.

For example if I enter abcdf\befg

it would do the following:

 

ComWrt (comPort, buf, 1); // Where buf = "a"; ComWrt (comPort, buf, 1); // Where buf = "b";

ComWrt (comPort, buf, 1); // Where buf = "c"; ComWrt (comPort, buf, 1); // Where buf = "d"; ComWrt (comPort, buf, 1); // Where buf = "f"; ComWrt (comPort, buf, 1); // Where buf = "\b"; ComWrt (comPort, buf, 1); // Where buf = "e"; ComWrt (comPort, buf, 1); // Where buf = "f";

ComWrt (comPort, buf, 1); // Where buf = "g";

When there is more than one character I might have to read the string  GetCtrlVal (gPanelHandle, PANEL_TX_STRING, buf) and only send the last one? 

Thanks for any help.

This is more readable.

ComWrt (comPort, buf, 1); // Where buf = "a"

ComWrt (comPort, buf, 1); // Where buf = "b"  

ComWrt (comPort, buf, 1); // Where buf = "c"

ComWrt (comPort, buf, 1); // Where buf = "d"

ComWrt (comPort, buf, 1); // Where buf = "f"

ComWrt (comPort, buf, 1); // Where buf = "\b"

ComWrt (comPort, buf, 1); // Where buf = "e"

ComWrt (comPort, buf, 1); // Where buf = "f"

ComWrt (comPort, buf, 1); // Where buf = "g"

it seems the message title contains the solution you are searching for: EVENT_KEYPRESS is triggered each time you press a key when a control has the focus. have you tried it ?

Yes I am using it now. I just wanted to make sure that I was implementing this in the correct way. Sometimes the obvious isn't necessarily the most appropriate.

Confirmation always helps.

Thanks.
