Thank you Rui CToolBar - adding text to buttons Christoffer A. Andersen3-Dec-02 4:35 Christoffer A. Andersen 3-Dec-02 4:35  I have a toolbar derived from CToolBar consisting of several buttons. I created the toolbar using Insert->Resource->Toolbar but did not add any contents to the different buttons. I now want to add centered text to the different buffers (whose size and position changes when the main window changes) in run-time. Of course I have tried CToolBar.SetButtonText() but it just doesn't work. I have seen other people do the same thing, but my application doesn't work.... What am I doing wrong?

Anonymous3-Dec-02 2:44 Anonymous 3-Dec-02 2:44  Hi, how can I avoid that a scrollbar inside my listbox vanishes? I created a listbox with styles LBS_DISABLENOSCROLL | WS_VSCROLL. But when I resize the listbox so small that the scrollbar is the only visible part, the scrollbar disappears. Thanks for help.

I can post an example later if that is what you are looking for. If you are looking to manipulate Excel formating and such, then I can't help.

You MUST use overlapped I/O -> it is not quick hack and not easy. Prepare yourself for work. Try this @ home. (B&B) Transparent Bitmap on a CButton AnTri3-Dec-02 1:11 AnTri 3-Dec-02 1:11  Hello, how can I create a transparent Icon (not white...) or Bitmap to place on a CButton object. I use the .net IDE!

Mouse cursor over window doesn't change S O S3-Dec-02 0:57 S O S 3-Dec-02 0:57  The mouse cursor doesn't change over a window I created! (If I put the cursor over the edge, so I see the "size" cursor, it stays that way when I move it over the window) Window creation: if (!m_wndTileset.CreateEx(WS_EX_PALETTEWINDOW | WS_EX_TOOLWINDOW | WS_EX_TOPMOST, AfxRegisterWndClass(CS_VREDRAW | CS_HREDRAW, theApp.LoadCursor(IDC_ARROW)), "Tileset", WS_SIZEBOX | WS_SYSMENU, CRect(), this, 0)) Any ideas? Do I have to do soemthing special to make it change? Re: Mouse cursor over window doesn't change Rage3-Dec-02 1:14 Rage 3-Dec-02 1:14  Override OnSetCursor (MFC) or handle WM_SETCURSOR (Win32) ? ~RaGE(); Re: Mouse cursor over window doesn't change S O S3-Dec-02 5:56 S O S 3-Dec-02 5:56  From MSDN: The default implementation sets the cursor to an arrow if it is not in the client area or to the registered-class cursor if it is. So it should already work??? ATL : Subclassing ComboBox Martijn3-Dec-02 0:47 Martijn 3-Dec-02 0:47  Hi, I've created a project with the ATL Com Appwizard and inserted a new ATL object, derived from ComboBox. It uses an internal variable m_ctlComboBox which is of type CContainedWindow. I want to be able to invoke methods like InsertString and the likes from VB without programming stubs for them, since the implementation is already done by ComboBox itself. How can I publish the internally used control so VB sees these methods and properties? I've now replaced the type of m_ctlComboBox from CContainedWindow to CContainedWindowT<CComboBoxT<CWindow> > deriving from a template defined in ATLControls.h. I just thought it might help, but no such luck.... Memory Clean suresh_sathya3-Dec-02 0:19 suresh_sathya 3-Dec-02 0:19  i want to pass two strings from vb to a dll written in vc++. downlaodfile(char *str1,char *str2) { } is the parameter declaration is correct.Is we have to free any memory after the function ends.Any error pl reply Re: Memory Clean Christian Graus3-Dec-02 0:22 Christian Graus 3-Dec-02 0:22  Because the char * are being passed into the function, I would expect the function that passes them in to take responsibility for cleaning them up. Is VB capable of producing char *'s ? Personally, I'd pass in std::strings, because then I'd know they were being cleaned up.

VB has always lacked even that... - Shog9 04-09-2002 Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002 Re: Memory Clean dabs3-Dec-02 3:00 dabs 3-Dec-02 3:00  I would suggest that you use BSTR instead of char* . Assuming both parameters are [in] parameters then you don't have to worry about the memory these strings occupy. If however you are returning something in one of this parameter then you must use an allocation scheme VB understands. I would suggest you create a simple COM object and define this function in it. COM defines wery well all issues regarding string manipulation. You would also definitely use BSTR there. And PLEASE use more descriptive variable names than str1 and str2. What do these parameters do? There's absolutely no way to tell. Wenn ist das Nunstück git und Slotermeyer? Ja! Beierhund das oder die Flipperwaldt gersput!

Michael Fat bottomed girls You make the rockin' world go round -- Queen Flicker free List Ctrl ? Christoffer A. Andersen2-Dec-02 23:15 Christoffer A. Andersen 2-Dec-02 23:15  I have a class derived from CListView and a list ctrl (report style) derived from CListCtrl lying beneath. When clicking a list item with the right mouse button, I'd like to change the color of the text. This is done in CMyListCtrl::DrawItem - no problem... When moving the mouse while holding the right mouse button, several items' colors may be changed (redrawn). This is where I have problems: Everytime a new item's color is changed, the whole control is redrawn causing flickering. I want to get rid of this flickering. Double buffering is suggested to be used in CMyListView::OnDraw(), but I have no possibility of drawing the particular item in this function. Do you have any suggestions?

Andersen 3-Dec-02 0:00  Hi - it's me again. I kinda solved this myself. A silly question really. The problem had nothing to do with what I thought it had. All I needed to do in order to solve this problem was to use InvalidateRect() instead of RedrawWindow() Probably a newbie mistake. Won't happen again - I hope.
