Thanks - I knew I wasn't being completely accurate but couldn't remember the function I set it in. It wasn't PreSubclassWindow, but I'm sure it has the same effect.

Re: Owner Drawn Buttons

The problem is not of setting the owner draw style (which is enforced at the end of PreSubclasWindow), it is finding out what type of control it is (checkbox, button or radio button).

If the owner draw style is set in the dialog editor then because button styles are not mutually exclusive you can't tell what type of control it was.

P.S. Unfortunately (for you) it does use MFC. Feel free to do a non-MFC conversion Wink | ;)

How do i get the HWND for PostMessage

I have a main Dialog application wich instantiate a new Dialog Like this...
m_pThread= AfxBeginThread(RUNTIME_CLASS(CMultiThread));
CMultiThread is a CWinThread .
This one takes care of Showing the new dialog box on the screen
BOOL CMultiThread::InitInstance()
{
CPostDialog Dlg;
//CoInitializeEx(0, COINIT_APARTMENTTHREADED);
CoInitializeEx(0, COINIT_MULTITHREADED);
m_pMainWnd= &Dlg;
Dlg.DoModal();
return TRUE;
}

Everythings is working fine.
On the ExitInstance() of this thread i want to post a message to the caller (Main Dialog) that CPostDialog is now over.
The problem is no matter what i try i can't get the HWND of
the caller.
I think that i should get the HWND in the InitInstance
What i did so far in the main dialog is to declare a public variable like this
HWND m_LocalWnd;
Then on the OnInitDialog() of the main dialog

m_LocalWnd =m_hWnd;

Then i change the InitInstance of my CWinThread like this
BOOL CMultiThread::InitInstance()
{
CMessageTestDlg pApp;
m_HwndSource = pApp.m_hWnd;
CPostDialog Dlg;
//CoInitializeEx(0, COINIT_APARTMENTTHREADED);
CoInitializeEx(0, COINIT_MULTITHREADED);
m_pMainWnd= &Dlg;
Dlg.DoModal();
return TRUE;
}
CMessageTestDlg is already running and i should be able
to get the HWND..
but it always return 0
What is it wrong.

The line

   CMessageTestDlg pApp;
<\PRE>
makes a new instance of the CMessageTestDlg class - it does not give you access to the global CWinApp derivative in your main thread. Use AfxGetApp() instead (I'm pretty sure it works across threads, but you may check to be absolutely sure). You can, however, not use AfxGetMainWnd() as this is thread-specific.

How do I disable system menu buttons

3-Sep-01 21:40

I want to display the minimize box only and not the close or maximize buttons. Is there any way to do this?
Alternatively is there any way to add a button to the title bar and use it instead.

Thanx...

To disabled the maximize button do this in PreCreateWindow()

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs

cs.style&=~WS_MAXIMIZEBOX;

return TRUE;
}

To disable system menu do this:
cs.style&=~WS_SYSMENU;

Re: How do I disable system menu buttons

This only grays out the MAX box...
> cs.style&=~WS_MAXIMIZEBOX;

This disables the entire menu...
> cs.style&=~WS_SYSMENU;

What I need is remove the maximize and close buttons, not just gray them out. I only want the minimize button to appear.

But thanx anyway...

Is it the main app window?

How bout:

HMENU hmenu = GetSystemMenu ( hwnd, FALSE );
DeleteMenu ( hmenu, SC_CLOSE, MF_BYCOMMAND );

later
Oops - just realized that you want to get rid of the buttons entirely - this won't do it. You may have to take over WM_NCPAINT handling...

TrackPopupMenu - What am I doing wrong?

James Bird3-Sep-01 21:31

3-Sep-01 21:31

I am writing a Win32 program (no MFC), and I need to display a context menu.
Every thing works fine, except that the size of the menu is wrong.

It looks like the vertical size of the menu is spot on, however the horizontal size is as small as you can get thus not displaying the menu items.

Is there a function I need to call before calling TrackPopupMenu?

Thankyou Smile | :)

Re: TrackPopupMenu - What am I doing wrong?

You need to get the submenu:

CMenu * m_Popup;
CMenu m_SysTrayMenu
<BR>
// load your menu resource
m_SysTrayMenu.LoadMenu(IDR_MENU1);
<BR>
// display the popup menu
  POINT CursorPos;
  GetCursorPos(& CursorPos);
  m_Popup=m_SysTrayMenu.GetSubMenu(0);
  m_Popup->TrackPopupMenu(TPM_RIGHTALIGN,CursorPos.x,CursorPos.y,this,NULL);

I believe the function you want is called GetSubMenu(HMENU menu, int Pos)

I have played a little around and have been unable to reproduce your problem. Here's a couple of thoughts anyway:
- the coordinates are in screen coordinates, not client (as your POINT that you receive are).
- the two unused parameters in TrackPopupMenu should be 0 and NULL, respectively.
You could try out TrackPopupMenuEx and see if that works, although I cannot really se why it should make a difference.

If you still have problems post some code for us to look at.

Cheers

Use GetSubMenu(0) this will sort the height problem out

e.g. usage in WTL

::TrackPopupMenu(menuPopup.GetSubMenu(0), TPM_LEFTALIGN | TPM_RIGHTBUTTON, rc.left, rc.bottom, 0, *this, NULL);
