Select more than one item in a listbox Anonymous3-Jan-00 7:07 Anonymous 3-Jan-00 7:07  I have a dialog based app with three listboxes. I used AddString("") to add several items to each string. When I run the program, it allows me to select all the items at one time. I want the user to only be able to select one item at a time. How do I do this? Thanks, Stephanie RE: Select more than one item in a listbox Andrei Zenkovitch3-Jan-00 8:03 Andrei Zenkovitch 3-Jan-00 8:03  Hi, If you create list boxes explicitely using create function then make sure that you didn't specify LBS_EXTENDEDSEL or LBS_MULTIPLESEL style. If you use dialog editor for creating the template for your dialog then you have to display a property dialog for the list box control. On this dialog you have to select the second page "Styles" and in the "Selection" combo box you have to choose "Single" item Regards, Andrei Zenkovitch Dundas Software ================== The original message was: I have a dialog based app with three listboxes.

It makes the list box gray (instead of white) and won't unselect item. ie. The default selection is String1. If you click on String2, both are blue. If you click again on String1, it stays blue. It's impossible to select only one string, unless you take the default. I'm not sure what's going on.

In an earlier version of the dialog box, I was changing the color. I don't need that anymore, and when I took out the code, it started working as it should. Thanks for your help!

How do I do this? Thanks, Stephanie How do you use a Rich Edit Control in a dialog? Steve Roach14-Dec-99 3:35 Steve Roach 14-Dec-99 3:35  I am using VC5. If you place a Rich Edit (RE) control in a dialog from the controls toolbar and bring up the class wizard the RE control ID is not listed in the list of member variables. Is this correct? How are you supposed to exchange data with the RE control? The object ID for the RE control does appear in the Message Maps tab of the class wizard. Do I write handlers (as required) for the 26 NM_ and EN_ messages listed? Do I manually add a CRichEditCtrl member variable to the dialog class? Thanks again for any help supplied Steve RE: How do you use a Rich Edit Control in a dialog? Jesse Ezell14-Dec-99 14:43 Jesse Ezell 14-Dec-99 14:43  This is probably due to the fact that the ID is not yet linked with the dialog. If VC5 works the same as VC6 in the resource editor, hit ctrl+w after clicking on the richedit control...it should automatically bring up the RichEdit ID in the box (then, make sure to select the dialog class, if it is not already selected, so that your inserted functions go in the right class). ================== The original message was: I am using VC5.

RE: Explorer.exe Mike Dunn14-Dec-99 15:21 Mike Dunn 14-Dec-99 15:21  I remember seeing how to do this in "Visual C++ Windows Shell Programming" (a cool book BTW). The topic isn't in the index (and I'm not really up for searching through 660+ pages for it) so this is from memory... I believe you get the HWND of the window with class "Program Manager" and send it a WM_CLOSE. Then re-run Explorer to restart the shell. The only trouble with this is that some of your tray icons will be blown away. --Mike-- ================== The original message was: How can I reload explorer.exe through C++?

Any suggestions? Rich Edit Ctrl in dialog? Steve Roach11-Dec-99 12:59 Steve Roach 11-Dec-99 12:59  I'm using VC++5. I find that when I use the resource editor to put a Rich Edit control in a dialog that is used either as part of a property sheet or as a dialog started from a menu option that the DoModal dialog callreturns -1 indicating that the box could not be created. (The same thing happens in VC++6). I searched the help and found no mention of any such limitation - it seems logical to be able to do it as the control is in the toolbar in the resource editor. I guess I must be doing something wrong. Any ideas? Steve RE: Rich Edit Ctrl in dialog? Jesse Ezell11-Dec-99 19:07 Jesse Ezell 11-Dec-99 19:07  Yes, there is a mention in the help files, you must have missed it though, since it is indirect. In order to use a RichEdit control, you must make sure that the RichEdit control DLL is loaded to do this, make sure that before your dialog or property sheet is loaded, you call AfxInitRichEdit() RE: Rich Edit Ctrl in dialog? Andrei Zenkovitch13-Dec-99 8:24 Andrei Zenkovitch 13-Dec-99 8:24  Hi Steve, The problem has to do with the fact that when CDialog tries to create a dialog window from the resource template internally it does by calling ::CreateWindowEx() function. The most important argument in this function is the name of the window class (like "Static" for static control or "Edit" for edit control). It is required that before window is created its window class must be registered. MFC does it internally for common controls but not for rich edit control which implementation resides in different dll. So when you call DoModal() function the internal Windows implementation will fail to create the rich edit control and therefore the creation of the dialog will fail as well. Now how to fix the problem. You just have to load the dll that contains rich edit control implementation in your InitInstance() function: HINSTANCE hRichEdDLL=::LoadLibrary(_T("RICHED32.DLL"); if(g_hRichEdDLL==NULL) TRACE(_T("Cannot load library to display RichEditTextControl")); Regards, Andrei Zenkovitch Dundas Software P.S. I assumed you were using MFC. If it is not the case then above mentioned explanations are still valid. ================== The original message was: I'm using VC++5.

I tried trapping the VK_ESCAPE message, but it still got destroyed. Can anyone help me? RE: Modeless Dialog Boxes Anonymous11-Dec-99 12:55 Anonymous 11-Dec-99 12:55  You have to override the OnCancel function of the dialog box. RE: Modeless Dialog Boxes Stefan Ernsperger13-Dec-99 20:16 Stefan Ernsperger 13-Dec-99 20:16  If you dont't want to overwrite all the func (OnCancel, OnOk, ... (and don't forget Alt+F4), you can overwrite the PreTranslateMessage func and try catching ESC, Return ... BOOL CSelectToolDlg::PreTranslateMessage(MSG* pMsg) switch (pMsg->message) { case WM_KEYDOWN: switch (pMsg->wParam) { case VK_RETURN: pMsg->wParam = 0; break; case VK_ESCAPE: pMsg->wParam = 0; break; } break; Hope this helps erni VB Control Arrays in VC++?

It is a member of CWnd, so you can be sure that all window controls have it. Use it as: ShowWindow( SW_SHOW ); -- to make a window visible ShowWindow( SW_HIDE ); -- to hide a window Peter Zajac Dundas Software ================== The original message was: How does one make static text (in)visible in VC++?

In other words, when you have some common code that other apps may need to use, you put it in a DLL and presto.

Thanks, Marc Change CEdit font Jeremy Davis10-Dec-99 3:42 Jeremy Davis 10-Dec-99 3:42  This must be easy BUT..... I've tried to change the font on a single CEdit box in a dialog. I've used the following code.... CFont m_Font; m_Font.CreateFont(.........); GetDlgItem(CEDIT_ID)->SetFont(&m_Font); Now this "sort of" works. The font is changed BUT the line size of the CEdit is not changed accordingly so the lines below overlap lines above. Can someone please sell me how this can be done?? Thanks in advance Jeremy Davis
