OpenInsight 32-bit Specific

I have a multi-select table but wish to control whether or not multiple rows are required. The best way for me to achieve this would be to trap whehter the user simply left-clicked, or pressed Shift+Left click or CTRL+Left click.

I can trap simple left clicks OK (Qualify_event & Winmsg) - but anyone any idea how I can trap CTRL+Leftclick or Shift+Leftclick?

Cheers, Rich

Richard try this…

During the trapping of the left click, you can check if the shift and/or ctrl keys are pressed. You check for these pressed keys by using the following sentences…

DECLARE FUNCTION GETASYNCKEYSTATE

SHIFTKEY_PRESSED=(BITAND(GETASYNCKEYSTATE(16),32768) EQ 32768)

CTRLKEY_PRESSED=(BITAND(GETASYNCKEYSTATE(17),32768) EQ 32768)
