how to check if form was activated

Jassim Rahma

i have an MDI child (MDI1) form which I am opening another MDI child (MDI2) from that form. How can I check if MDI1 was ctivated after closing MDI to refresh it? do I have to use Enter or Activated events?

use this.ActiveMdiChild It will return the MDI child form that is currently active. If you want to activate another form just use frm2.focus(); :rose:

I don't want to focus it. well, let me explain it more.. MDI2 is an edit form of MDI1 so MDI is just viewing the data where MDI2 is the edit. when the user clicks on the edit button (on MDI1) it will open MDI2. when the user click save (on MDI2) it will close MDI2.. now I want to know if any data were changed and refresh the data on MDI accordainaly.

Well, Do the refresh of data when form is activated. Write the code inside Form_Activated to refresh the form with new data. Dont forget to set a flag when edit is done and recheck the flag within form_Activated. Otherwise the data will be refreshed every time you activate the form.:cool:

Create a bool on MDI2, set it to true if data is edited. Create a readonly property for this bool on MDI2 and check it from MDI1. Refresh if true.

of course, you should use these event. for example, use 'closing event ' to check if MDI1 was activted. or you can use WINAPI ('FindWindow')to Find out that 'WinForm', and then check if it was actived.
