Toolbar Button Enable/Disable jdgonko30-Dec-03 5:49 jdgonko 30-Dec-03 5:49  Hello. I've created a standard MFC app using VC++ 2002. The toolbar works great and uses CMainFrame::OnDatabase and ::OnTransport to fire-up a child window specific to the button's stated purpose. So far, I have two buttons, one to fire-up the "database functions" window and then one for the "transport functions" window. BUT, I need to ensure that only ONE child window that does the specific purpose is created when the button is pressed. It doesn't make sense to allow the user to hit a button multiple times, creating multiple "database" or "transport" function child windows... I want to disable a specific button when the child window is visible. So, I've been trying to work with the ON_UPDATE_COMMAND_UI messages to disable the toolbar button when the child window is successfully created from CMainFrame and then re-enable the toolbar button when the child window is closed by catching the WM_CLOSE message in CMainFrame. I've experimented with various codings, trying to do the toolbar notifications in both CMainFrame and then, in the two child window objects I have created so far. No real success yet. Could someone provide me with some source code showing an example of what I need to accomplish?? There's gotta be an accepted way to accomplish this. Thanks!

In the ON_UPDATE_COMMAND_UI callback, you can do something like : ... pCmdUI->Enable( ( IsYourChildWindowVisible() == TRUE ) ); ...

("Computer Networks" by Andrew S Tannenbaum ) Re: Toolbar Button Enable/Disable jdgonko30-Dec-03 8:02 jdgonko 30-Dec-03 8:02  That is working A-OK but... If both child windows are visible, and one loses the focus, the toolbar button of the lost-focus window re-enables itself. In other words, "visible" doesn't actually mean visible but rather "has input focus." Is there a function to use other than IsWindowVisible that will detect windows that are visible but perhaps don't have the input focus? Thanks again. Getting there. Joe Code in each window's .h/.cpp respective files is (only one shown below): (in .h file) afx_msg void OnUpdateToolbarButtons(CCmdUI* pCmdUI); (in .cpp file) ON_UPDATE_COMMAND_UI (ID_TRANSPORT, OnUpdateToolbarButtons) void CHelloWnd::OnUpdateToolbarButtons (CCmdUI* pCmdUI) { if (IsWindowVisible() == TRUE) { pCmdUI->Enable (FALSE); } if (IsWindowVisible() == FALSE) { pCmdUI->Enable (TRUE); } } Other file works with the CDatabaseWnd object and addresses that toolbar button message ID and object. Re: Toolbar Button Enable/Disable jdgonko30-Dec-03 11:12 jdgonko 30-Dec-03 11:12  AHA! Got it working properly but unfortunately did have to use two global vars to track the two child window states. Maybe I'll come back to this problem in the future. I'm burned-out from tweaking it today to work right... No, I'm not a professional programmer. Thanks again Maximilien! Joe sending long string to Printer pnpfriend30-Dec-03 4:50 pnpfriend 30-Dec-03 4:50  Hello all. how can I print a very very long string to the printer? I tried to cut the string at every 50th letter and print it on next line. but it doesn't look nice on the paper after it printed out.. sometime there is a lot of space to fit all the string characters on one sentence. I want to know if there is a way to find out that the string going beyond the right side of the page? I'm using CDC.TextOut, StartDoc,EndDoc to print a very long string Thank you Re: sending long string to Printer Roger Allen1-Jan-04 23:55 Roger Allen 1-Jan-04 23:55  This example of mine in the printing section should help http://www.codeproject.com/printing/printlongtext.asp[^] Breaks lines across pages etc for you automatically.

Under 2000 I manage to draw OVER window's menu-border and thus have my own menu-border. Under XP with Flat Menus, XP decides to draw the border AFTER I draw my menu and thus it overrides my border and I get a white-border. I want to disable FLAT menus, but only for my application/menus, is this possible ? thanks how to beautify a button in a dialog? yunhe30-Dec-03 2:54 yunhe 30-Dec-03 2:54  in vc++ , i want to make a button beautifull in a dialog .i.e. the shape,font,color,transparent 云鹤 I'm a beginer of MFC. what i want to do is changing an apple with you.Of course, the important is learning from all of you.

Saving Documents Without Confimation Dialog volkan87829-Dec-03 22:53 volkan878 29-Dec-03 22:53  Hi, I have an MDI project. When some changes occur in a view i call the view's document's SetModifiedFlag() method and when the user attempts to close the child frame, it asks to save the recent changes and that's OK. I also have a Save Project button on the toolbar and when it is pressed it calls CDocTemplate::SaveAllModified() method and saves the modified documents but the problem is it still pops a confirmation dialog. It looks rather silly when the user presses "Save" and it says "Do you want to save?".. Is there a way that i can "silently" save the documents without displaying the confirmation dialog box? Any idea is welcome. Thanks in advance. Re: Saving Documents Without Confimation Dialog Azghar Hussain30-Dec-03 1:57 Azghar Hussain 30-Dec-03 1:57  Hi, I Think this is possible. Just try to overwrite the CFileDialog() or Do the serialization by skipping CFileDialog(). This is a huge mess I think. I am tryieng this application by myself. If I get the solution I will surely let u know. bbye Salman Live and Let live
