Overlapped VS Popup window rrrado2-Dec-02 3:10 rrrado 2-Dec-02 3:10  What is the exact difference between them ? I create next modeless dialog from main dialog. (MFC dialog based application). But it doesn't matter what the type of dialog in resources i use - result is the same. rrrado Re: Overlapped VS Popup window valikac2-Dec-02 9:05 valikac 2-Dec-02 9:05  I believe one difference is that an overlapped window has a frame is can be resized.

I have currently included the CTreeCtrl in my project, and now I want to be able to populate individual nodes, with the information stored in my database. Any assistance appreicated. Regards Re: CTreeCtrl / CDatabase act_x2-Dec-02 6:49 act_x 2-Dec-02 6:49  Assuming that you have something like a recordset, whenever you iterate thru the recordset you could add items to the Tree using the InsertItem() method . Also in one of my projects I needed to record changes made to the CtreeCtrl for which I had a structure array .

Then I maximize my view and I set my frame menu to the original menu (SetMenu(pOrgMenu)). The menu appears, but the control menu (maximize, minimize, close button) of my child view don't appear in the menu bar, as it should do. The only possibility that I have is to call MDIRestore() MDIMaximize() of my child window. But this results in an ugly window flash. I have already tried all things I know about MDI frames and child views, but non of that worked. Has anyone an idea, how I can solve this problem? Thanks in advance Re: MDI Child view control menu KaЯl2-Dec-02 5:03 KaЯl 2-Dec-02 5:03  I never tried to set and remove menus that way, so I won't be able to directly help you. I've implemented once the maximizing of a view of an MDI application this way CMyView::Maximize() { // maximize window GetParent()->ShowWindow(SW_MAXIMIZE); } The parent of the view is the ChildFrame, it's the one which is resized. The resizing of the contained view is done by the Child frame (CChildFrame::OnSize or CChildFrame::OnExitSizeMove). HTH, Ohé Partisans, Ouvriers et Paysans C'est l'alarme! Le Chant des Partisans Re: MDI Child view control menu CodeBrain2-Dec-02 6:01 CodeBrain 2-Dec-02 6:01  Thanks for the reply, but unfortunately that's not exactly what I need. To be clear: I remove NOT the control menu of my view, but the applications main menu. If you maximize a view, the control menu of the view will be displayed in the main menu bar of the applications main frame. If I switch the main menu off and then maximize my view, the control menu of the view is not visible, because the main menu in which the control menu should be displayed is not visible. That's correct. But if I switch the main menu back on, the views control menu is not displayed. I can only solve this if I restore and maximize the view, which causes an ugly flash of my view. Re: MDI Child view control menu Alois Kraus2-Dec-02 6:37 Alois Kraus 2-Dec-02 6:37  I would try to solve this in another way: Draw these buttons (minimze,resize,close) by yourself in the menu bar. Remember what view is currently maximixed. And send the message WM_CLOSE, . . to the current view by yourself. I know this method requires some work but this way you will surely succeed.

Thank you very much for your effort. Yes, you may be right with that menu pointer. If I use your test app. it seems to work. If I remove pActiveFrame->ShowWindow(SW_RESTORE); from your code, it has the behavior I need. So the method how I handle the old menu seems to be the problem. I will try to change my managing of the menus to make it work. Thanks again for your work.

Johann Gerell2-Dec-02 1:59 Johann Gerell 2-Dec-02 1:59  Hi, An hour ago or so I was hit by the lightning when I realized that I hadn't a clue on how MS implemented the set of GetSafe... functions. I can not find their implemntations in the MFC sources. Where can I find them, or, better, could someone please explain to me how a member function can be called for NULL object without wreaking havoc? Thanks! Don't _think_ you are, _know_ you are! (Morpheus in The Matrix) Re: Implementation of GetSafeHandle and siblings. Tim Smith2-Dec-02 2:30 Tim Smith 2-Dec-02 2:30  As long as the method isn't virtual, there is no problem with calling a member function where "this" is NULL. At no time is "this" ever dereferenced during the call process. So as long as you check for "this == NULL" in the member function, things will work just fine. return this ? m_hWnd : NULL; Tim Smith I'm going to patent thought. I have yet to see any prior art. Re: Implementation of GetSafeHandle and siblings. Johann Gerell2-Dec-02 2:58 Johann Gerell 2-Dec-02 2:58  Thanks, It's so much fun to learn new details on C++. I've always (up until now) checked for NULL _before_ calling a member function for an object that may be NULL. Now I have my very own GetSafe... functions But, the nitpicker in me still wants to know where these MFC functions are implemented. Have I failed to install _all_ MFC sources (is that even possible?) perhaps... Re: Implementation of GetSafeHandle and siblings.

I can set the scrollbar ok, but I can't figure out how to scroll the text properly. Can anybody suggest how i can instruct a CListBox to scroll by a given amount, and have the listbox take care of updating both the scrollbar and the client area (i.e. have it scroll the text correctly). Clearly CListBox knows how to do this, because if i just grab the scrollbar of a standard CListBox, it works. So how do i ask it to do this for me. Effectively, i want to 'emulate' having dragged the scrollbar.

These should help you. Or you could simply send the listbox WM_VSCROLL messages.

C.R.Naik Re: http GET/POST request through proxy rrrado2-Dec-02 0:35 rrrado 2-Dec-02 0:35  Send GET/POST as usually, instead that you will connect your socket to proxy server instead of HTTP server. Headers will remail the same, in simple case (no proxy authorization ...) rrrado Re: http GET/POST request through proxy geo_m2-Dec-02 2:38 geo_m 2-Dec-02 2:38  good behavior is also to send the complete url of the request, which is not necessary when using direct connection. Instead of <br /> GET /index.htm HTTP/1.1<br /> Header: Value<br /> which is allowed for direct connecting, you should use the full syntax: <br /> GET http://www.codeguru.com/index.htm HTTP/1.1<br /> Header: Value<br /> from this the proxy will be able to know, where you want to connect Minimize to task bar rrrado1-Dec-02 23:26 rrrado 1-Dec-02 23:26  I have modeless dialog windiw created in separate thread. Clicking to minimize button cause shrinking this window to size of title bar and it moves to bottom left corner of rhe desktop. How to minimize this window to task bar ? And show this window in task list so i could switch to this window by Alt+Tab ? Thank you rrrado Re: Minimize to task bar Paul M Watt2-Dec-02 9:53 Paul M Watt 2-Dec-02 9:53  It sounds like you are using the WS_EX_TOOLWINDOW style. What you will need to do is remove the WS_EX_TOOLWINDOW style in the SC_MINIMIZE portion of the WM_SYSCOMMAND message handler, and restore this style setting when the SC_RESTORE event is received in the WM_SYSCOMMAND handler. The toolwindow prevents your windows from appearing in the Taskbar, however it also makes your windows minimize to the desktop like you have described.
