Is this safe to do?

The downfall is having the variable ChangesSaved or whatnot, and for each object on the GUI you have to set that flag if an event happens on it, which is not really TOO big of a deal but by doing it you get the feature you want
so here for example is a checkbox to set some option or another...
I set the flag, re-enable the Apply button etc...
Now, cool thing is that sometimes users press OK without pressing Apply, easily fixed by that flag, if istrue ChangesNotSaved then sendmessage GetDlgITem(oDlg,%idapply),%BM_CLICK,0,0 and walah you just pressed the apply button for them, and all of your code can be called in teh apply code and not duplicated....

It works for me, everyone has a different style but it works

             Case %IDOK
                SendMessage GetDlgItem(oDlg,%IDAPPLY) , %BM_CLICK, 0, 0


             Case %IDCHECK2
                  ChangesNotSaved = %TRUE
                  Control Enable oDlg, %IDAPPLY
                  Function = 1
                  Exit Function

Scott,

You are completely correct! That's exactly what I want to do. I was unsure as to what extent the "dialog end" function worked. Thank you for clearing that up for me!

If I understand what you are doing, NO you can't do that...

If the window is closing you want to read all of the data etc and then do say, registry chagnes, change values etc? (Like an options dialog box???)...

I create an apply button and a static variable to see if changes were made.
If changes were made and WM_DESTROY comes down, then send a message to apply to process.

    Case %WM_CLOSE
         If IsTrue ChangesNotSaved Then
            Result = MsgBox("Save changes?",%MB_ICONQUESTION Or %MB_YESNO,Mine)
            If Result = %IDYES Then
                SendMessage GetDlgItem(oDlg,%IDAPPLY) , %BM_CLICK, 0, 0
            End If
         End If

Hello,

Can you safely access editbox controls when processing the WM_DESTROY message. My program calls "dialog end cbhndl" when the cancel button is pressed. I then process the WM_DESTROY message, reading all the editboxes and saving the strings to the registry. Should I be doing this before I call "dialog end cbhndl" ?
