mfc >> Dialog Creation

by James Simpson » Sat, 29 Nov 2003 17:13:38 GMT

Hello,
I want to insert code for a dialog box. This code needs
to be inserted after the creation of the dialog box, but
while the dialog box is being shown. Would this be some
sort of override or event? The project that I am doing
that requires this is a MFC type application. I am using
Visual C++ .NET 2003 ...
Thanks in advance.

Sincerely,
James Simpson

Post yourself a message in OnInitDialog. The message handler will be
called after the dialog is shown.

#define MY_MESSAGE (WM_APP+1)

// OnInitDialog
PostMessage(MY_MESSAGE, 0, 0);

// in message map
ON_MESSAGE(MY_MESSAGE, OnMyMessage)

// message handler must have two parameters
LRESULT CMyDialog::OnMyMessage(WPARAM, LPARAM)
{
... do something
return 0;
}

1. Calling SetWindowTitle Just After Dialog Creation Causes

2. ? Post Window (Dialog) Creation Flag 

Hi,

I've searched high and low (mostly low) but can't find anything about how to determine if a window (specifically a dialog and it's
controls) is completely created.

As you know, a window may/will receive all kinds of messages while it's being created.  Unfortunately, sometimes we write message
handlers that are to be executed AFTER the dialog and all of it's controls are created.

For example, moving/sizing controls in a dialog box is done in OnSize as expected.  However, WM_SIZE is sent to the window before
the controls even exist.  To avoid an exception, you have to check that the controls are there before performing the actions on
them.

Instead of using the common method for testing the control's existence:

  OnSize {
    if (GetDlgItem(IDC_SOME_CONTROL)!=NULL) {
  //or
  //if (SomeControl.GetSafeHwnd()   !=NULL) {
  //  perform actions on controls
    }
  }

I would like to use a simple one-shot flag.  That is, I am trying to make a simple member boolean that is set to false in the
constructor, then set to true when the window is finished being created.  From then on, any tests for control existence would just
check that instead of calling a function.  While it doesn't seem like a big deal, it could be.  For example, if you are resizing a
window, it will receive a lot of WM_SIZE messages, and having it do the extra overhead could possibly have a noticeable impact.
Even if it doesn't, using a flag is just more elegant, that's what _flags_ are for.

However, I cannot find a way to determine when the window is finished being created.  I vaguely remember there being some kind of
message that is sent when it's done but I can't find it, so I'm not so sure anymore.

I tried setting the flag in OnSize but it didn't work because it was only called once on dialog creation, at which point the
controls didn't yet exist; it was not called again after the controls were there.

Does anyone know of a way to determine if the window is completed?


Thanks a lot.

Multi threading.

You run the progress bar dialog on a second thread and update it via thread 
safe calls using invoke to fire a method saftely on the second thread when 
it needs an update.
