Negate the modifier test and Evaluator

Help & Support
1

We can use a ! character to negate the modifier test.

I have button @hideif:=SysInfo("USBInstall") to show button if Dopus is not installed on usb.
But if I have @hideif:!=SysInfo("USBInstall"), button is always display.

(I know that @showif exists)

What is the good syntax ?

@hideif:=!SysInfo("USBInstall") should work, since the Evaluator includes a ! operator.

(Negating a more complex test might require other changes, or putting the whole thing in brackets.)

Do you mean always hidden?
