How to know when the dialog is activated?

[freehawk]

Hello everyone. I have a dialog attached in a frame, the propery of dialog is "child", in the dialog there are some edit boxs, comboboxs and buttons. When these controls in dialog got focus, I want to catch the active event. I tried to add WM_ACTIVE to dialog, but it can not be called. How to know when the dialog is activated? Thanks. -Freehawk

When these controls in dialog got focus, I want to catch the active event. for that u can use EN_KILLFOCUS and EN_SETFOCUS events of edit box
