Hi!
I try your codes again. As a result the gotfocus method gives a good effect, and the lostfocus method is late a step: then I jump to another application, I do not see any change. However, when I return to click on the main window of VFP, I see the message "lostfocus", and I click secondly on the main window of VFP, I see the message "gotfocus". In addition, if I click on a child window of the main VFP windows, I get anything!
Some lines give you more information.
Finally, I cannot apply these codes in my application yet because I get the above problems.
Best regards!
