If the table cell can not receive a virtual key?

Question

Hello,
Want to execuate a "copy/paste" function in the table control. I hope type the "Ctrl+c" to copy  text in a cell, but nothing to do with the "ctrl" key pressed.

Table can receive and trap Ctrl + someCharacter in keypress event: you can discriminate the keys pressed with this code:
if (event == EVENT_KEYPRESS) {
if (GetKeyPressEventModifiers (eventData2) == VAL_MENUKEY_MODIFIER) {
sprintf (msg, "Ctrl + %c pressed.", GetKeyPressEventCharacter (eventData2));
MessagePopup ("Notice", msg);
else if (event == EVENT_VAL_CHANGED)
MessagePopup ("Notice", "Cell value changed.");
Unfortunately, if the table is in edit mode Ctrl-C and Ctrl+V appear to be trapped by the system at low level and not to be passed to the control callback. Within CVI you can trap EVENT_VAL_CHANGED event, but I see no way to discriminate between a user type-in and a paste operation except for trapping whether a previous keypress event was received, which can be a troubled way to go. I can't see a way to trap Ctrl+C.
There may be a method to get those event using some windows API but I don't know it.
Proud to use LW/CVI from 3.1 on.
