As I tried to look it up, I saw that you may be able to handle it as follows:

case WM_KILLFOCUS:
   if ( wParam != 0 )
   {
      WINDOWINFO wi;
      GetWindowInfo( (HWND)wParam, &wi ); // sorry, did not check for errors
      if ( (wi.dwExStyle & WS_EX_TOPMOST) == WS_EX_TOPMOST )
      {
         SetWindowPos( (HWND)wParam, HWND_TOP,
            0, 0, 0, 0, // ignored
            SWP_NOMOVE | SWP_NOSIZE |
            SWP_NOOWNERZORDER | SWP_NOSENDCHANGING );
      }
   }
   return 0;

Hope this helps (and hope I am not wrong!).

Thanks, just what I needed!

I'll check the wi.dwStyle for WS_POPUP or WS_POPUPWINDOW and if that window's RECT intersects my window will set the appropriate Z-Order for these two windows.

best regards,
norm

That's probably because it is not a Microsoft class.

Hi,

Sorry if this is the wrong forum to be asking this Frown | :(

Anyway, I'm going to install Visual Studio .NET 2003. I have Visual Studio .NET (ver. 7) installed already. Should I uninstall it and the framework before installing the newer version?

Thanks..;P

The answer depends on whether you still want to use version 7. I recommend uninstalling version 7 before installing .NET 2003.

Hi,

I’m initializing the dialog in my MFC application from the parent window as follows:

In TreeView.cpp,

void CMyTreeView::OnDraw(CDC* pDC)
{
/**/
CMfcTree dlg;

int ret = dlg.DoModal();

}

In MfcTree.cpp OnInitDialog() is as follows,

BOOL CMfcTree::OnInitDialog()
{
CDialog::OnInitDialog();

m_ImageList.Create(IDB_BITMAP1, 13, 12, RGB(255,255,255));

HTREEITEM hItem = m_nTree.InsertItem( "Root", 0,2,TVI_ROOT );
m_nTree.SelectItem (hItem);
m_nTree.SetImageList(&m_ImageList, TVSIL_NORMAL);
m_nTree.SetItemState(hItem, TVIS_BOLD, TVIS_BOLD );

//sets the background color

m_nTree.SetTextColor(RGB(0, 0, 0));

m_nTree.SetBkColor(RGB(255, 255, 255));

……………………………….
………………………………..

}

If I try to move the dialog I keep getting this error:
Debug assertion failed.
And it points to ASSERT(m_hImageList == NULL); in the winctrl2.cpp.

It has something to do with the line m_ImageList.Create(IDB_BITMAP1, 13, 12, RGB(255,255,255));

Please advise. I’m really frustrated with this error.

hi,

i'm programming an opengl program using visual studio .net. my project uses standard windows library(no mfc or atl). when i try to set a break point on a variable or a function, i keep on getting the error message "intellisense couldn't not find the specific location". does anyone know how to set the break point properly?

also, what file do i need to include in my project in order to use the "TRACE" function? is there a way to redirect printf's output to visual stuio .net's "output" panel/window?

thanx in advance.

File Tree Control???

Hello,

I Created a dialog which allows a user to select directories. I now have to code the tree control in which the directories appear. Is there a simple way to do this or do I have to handcode it all?

thanks

Thanks, but thats not excactly what I meant. It's hard to find an example, but I'm looking for one...

I'll describe the tree control in detail:
It contains the directories like the left splitter of the explorer.
It has check boxes so you can select directories,...

If I can get my hand on a picture or something, I'll post it.

thanks in advance.

Hello,

Add the WS_MAXIMIZE to the window style! If you are using MFC you should modify the CREATESTRUCT in the PreCreateWindow() function.

hope this helps

One solution is to add a handler for WM_SYSCOMMAND. Ignore SC_MOVE.

if (WM_SYSCOMMAND == message && SC_MOVE == (wParam & 0xFFF0))
return 0;

Toolbar ToolTip problem

C^hris L^osinger18-Aug-03 8:10

C^hris L^osinger

18-Aug-03 8:10

We have an MDI app where each MDI window has toolbars of its own (ie. there are multiple docking toolbars on the main frame wnd and at least one fixed position toolbar on the MDI child wnds). And all of the buttons, on all of the toolbars, have tooltips.

but...

When you start the program, the only tooltips that will show are those that belong to toolbars on the main frame wnd. The only way to make tooltips start working on the child wnds is to move the mouse over a separator on the child wnd toolbars first. After you do this, tooltips work fine for everything. Clicking buttons doesn't help, moving over enabled/disabled buttons doesn't help; the separator is the key. And, you don't have to hover over it, just a quick fly over on your way to a button will do it.

This is sub-optimal.

Any ideas?

CListCtrl::GetHotItem() XP & 2000

Member 53100518-Aug-03 8:03

I am finding this returns -1 in all cases in my program on a Windows 2000 machine. However when I run exactly the same code on another computer with in Windows XP it works correctly and returns 0, 1, 2 etc...

I need this as I have to know which image is being dragged across from the ListCtrl to a TreeCtrl.

Sounds strange to a novice like me and anyone who has come across a solution please HELP! Confused | :confused:

Failing this if anyone has bright ideas on a better method nice to hear from ya.

Btw, the imagelist was inserted using the InsertItem(int, LPCTSTR) not that that should make a difference.

Thanks

Sry - 'this' refers to the function GetHotItem() called as part of OnLButtonDown() in my CListCtrl. When one clicks on an image list - I expect the index of the currently selected image (0,1,2.. etc) to be returned.

This happens when I run in XP, but not when I run in Win 2000 (I just get -1).

I don't know. I sort of thought it might be linked in some way to messages given some problems with CListCtrl other people seem to have with - and it's mentioned in MS Knowledge Base in the following article "PRB: No ANSI Notifications from Control Created in OnCreate"(Article ID: Q148533).

I tried the solution in this article but it didn't seem to work and probably needs to be modified anyway - even if I am (somewhere!) on the right track.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
