ShowMessage issues (chaning window focus) 1

[GoldenEye4ever]

I'v written a "Windows VLC Forms" app consisting of roughly 10 separate Windows Forms.

I'm having a strange issue with using both the: "ShowMessage(...)" and "MessageDlg(...)" functions.

If I call either function from any Form, other than Form1 (the initial form in the VLC application), Form1 is given focus.

Steps to replicate issue:
- User navigates to Form2 (or any Form other than Form1)
- User clicks the "Save" button
- Form1 is given focus (this is the issue)
- MessageDlg(...) dialog is presented, and is given focus over Form1
- However, Form1 is still visible over Form2
- Once user closes MessageDlg(...) dialog, either by clicking one of the buttons or the "X", Form1 regains focus

My attemp to combat this issue:
- In my code, immediately following each instance of "ShowMessage(...);" and "MessageDlg(...);", I've added "Form2.focus();".
- However, this only restores focus to the correct Form after the dialog is closed.
Form1 is still covering Form2 while either dialog is visible


Please help


This weird issue happens both on XP and VISTA.

I initially developed my code in XP, using TurboDelphi.
However, I've re-compiled in VISTA using both "Delphi 2007" and "Delphi 2009 trial" to no avail

I'd be open to using custom Dialog boxes if anyone knows of any that work well

In my code, immediately following each instance of "ShowMessage(...);" and "MessageDlg(...);", I've added "Form2.focus();".

You'd have to add Form2.Focus(); before the message dialog, otherwise it waits for you to click "OK" before the code continues.

Also, how are you showing the other forms?
Formx.Show;
or Formx.ShowModal;?
Or any other way?

I'll try "Form2.Focus();" when I get home tonight.

I'm calling all the forms with "FormName.ShowModal();".

Also, I've noticed that this issue is not occurring in VISTA, sorry about that, it only happends in XP

I created a test app in delphi 6 on xp,
form1 has a button form2.showmodal
form 2 has a button showmessage('hello');
I had no problem

I'm not saying that this makes any sense

I've used ShowMessage(...) and MessageDlg(...) before many times with no issues.
But this time it's acting strange.

I initially developed the app in XP using Turbo Delphi (Delphi 2006), then moved it to my VISTA install using Delphi 2007.

It only seems to happen on an XP pc.

-------------------

Also, I tried adding the "FormName.setFocus()" on the line right before the ShowMessage(...) dialog, and it didn't help.

When I ran the exe on XP, it still did the screwy loss of focus.

Same as Aaron here. I did a test app where I had one button on Form1 that showed Form2, and then a button on Form2 that popped up a Dialog Box. Focus always returned to form2.
Delphi 3 and Turbo Delphi 2006 on Windows XP.

There must be something strange that is happening in your code.

Measurement is not management.

Thanks a lot for your efforts, I appreciate the help.

I really don't wanna re-write everything in Delphi 2007 from scratch as my app is roughly 12,000 - 16,000 lines of code now
I sorta lost count :S

Well, I'm away from my PC for the weekend.

I guess when I get home on Monday, I'll try making a new app in TurboDelphi, under XP.
Very simple, just like you guys described your tests.

Then I'll see if it gives my any grief.
Then I'll re-compile that same source in Delphi 2007 under VISTA and try running that exe on XP.

If I can't re-produce my error that way, then I'll be really annoyed.


I'll keep you all notified
