Re: Handling Button's Events Michael P Butler17-Sep-01 2:01 Michael P Butler 17-Sep-01 2:01  GetParent will give you a pointer to the parent dialog CWnd class. You can then cast it to your dialog class. CParentDialog* pParent = (CParentDialog*) GetParent(); How do I find out what workgroup/domain a host is in? Paul Vickery17-Sep-01 0:37 Paul Vickery 17-Sep-01 0:37  I am trying to find some code which will enable me to find out what domain or workgroup a given host is in. There is a function for this on Win2000, but I need it on NT4. Does anyone have any ideas? --- "The way of a fool seems right to him, but a wise man listens to advice" - Proverbs 12:15 (NIV) Re: How do I find out what workgroup/domain a host is in?

Paul Vickery17-Sep-01 3:20 Paul Vickery 17-Sep-01 3:20  Nearly. The link you posted (to NetWkstaUserGetInfo) gets info about the user's log-on domain info. However, just near this on MSDN was NetWkstaGetInfo which does the trick. Thanks, Paul. --- "The way of a fool seems right to him, but a wise man listens to advice" - Proverbs 12:15 (NIV) Ticks in menus Nick Armstrong17-Sep-01 0:30 Nick Armstrong 17-Sep-01 0:30  When I created my SDI aplication it gives you the choice of having a status bar, if you select yes to this, when your program is created it creates a View menu with a status bar option inside. When you click on this option, a tick appears next to this if the status bar is shown and disappears if not. I wish to copy this functionality with another menu item but cannot work out how it does this in my program, any ideas? Thanks in advance for any help, Nick Re: Ticks in menus Rashid Thadha17-Sep-01 0:52 Rashid Thadha 17-Sep-01 0:52  On your OnUpdate handler use pCmdUI->SetCheck(m_bCondition); Re: Ticks in menus Tomasz Sowinski17-Sep-01 0:54 Tomasz Sowinski 17-Sep-01 0:54  In ClassWizard, select the command ID. Then, from the list on the right side, select UPDATE_COMMAND_UI. Create the handler. Inside the handler, call pCmdUI->SetCheck with TRUE or FALSE. BTW: you should have a look on any MFC tutorial, like Scribble. Tomasz Sowinski -- http://www.shooltz.com Re: Ticks in menus Nick Armstrong17-Sep-01 2:03 Nick Armstrong 17-Sep-01 2:03  thanks, that worked and I have been able to open and close this dialog from the view menu with the tick being displayed/hidden but how do I get the tick in the menu to disappear when the dialog is closed using the close button on the top-right of the screen. I can handle it using OnClose() in the dialog's class but how do I link it to the menu. thanks for your help so far, Nick Re: Ticks in menus Tomasz Sowinski17-Sep-01 2:11 Tomasz Sowinski 17-Sep-01 2:11  ON_UPDATE_CMD_UI handler is called whenever user opens the menu. You have to check the state of the program and pass correct value to CCmdUI::SetCheck. Tomasz Sowinski -- http://www.shooltz.com a siple question about initialisation of pointer Gérald Mercet17-Sep-01 0:15 Gérald Mercet 17-Sep-01 0:15  I have an application, with several functions, and one of these have to return a pointer on COleDateTime. I know the size of the "array" of COleDateTime dates, 2, but i meet a problem when i start debugging when i look in the debug window. When i declare in the function a COleDateTime pointer i could use 2 way to do that. Firstly, i just could write: COleDateTime pDates[2]; and in the debug window i could see: pDates [0]->m_dt ->m_status [1]->m_dt ->m_status and in another way i could do it: COleDateTime *pDates=new COleDateTime[2]; and in debug window i only see that: pDates ->m_dt ->m_status So, what is the good way if i want to return 2 dates different? Thanks in advance gerald Re: a siple question about initialisation of pointer Michael P Butler17-Sep-01 2:11 Michael P Butler 17-Sep-01 2:11  You should be able to see the two dates in the debug window by modifing the debug view to look at, pDates[0] and pDates[1]. There is no real difference between COleDateTime Dates[2] and COleDateTime* pDates = new COleDateTime[2] (apart from where the allocate memory goes) Michael Display value of member in 'Variable' window Bartosz Lizak17-Sep-01 0:05 Bartosz Lizak 17-Sep-01 0:05  Hello all, as I mentioned I would like to display one (specified by me) member value of some class. You can observe this for MFC objects - e.g. CWnd displays value of m_hWnd in curly brackets. I looked into definitions of some MFC classes (CWnd and CString) and didn't see anything 'magic'. Does anybody know something about it? Regards Bartek Re: Display value of member in 'Variable' window Christian Graus17-Sep-01 0:09 Christian Graus 17-Sep-01 0:09  You mean in the debugger ? Just type it into the debug variable window. Christian As I learn the innermost secrets of the around me, they reward me in many ways to keep quiet.

Re: Display value of member in 'Variable' window Bartosz Lizak17-Sep-01 0:19 Bartosz Lizak 17-Sep-01 0:19  Hmmm, I wrote bad topic It's not so trivial ... I want to display value of specifed member while in 'Variable' window an object of the class containing this member is listed. For example: +this 0x00432990 {CManagersView hWnd=0x004604e6} Class CManagersView is derrived from CView and automatically displays it's 'primary' member - m_hWnd.

This works fine, however, I want to change the background colour of these buttons to a lighter colour. I'm guessing that I use SendMessage but as to which message and parameters I'm lost. Could anybody point me in the right direction. I've checked some articles but they are geared more to using the resource editor or owner-drawn buttons. Thanks in advance for any help, Nick Re: Button background Tomasz Sowinski16-Sep-01 23:47 Tomasz Sowinski 16-Sep-01 23:47  Sorry - you can't change the background of the button with one simple SendMessage. And processing WM_CTLCOLORBTN won't help either; here's what MSDN says: Buttons with the BS_PUSHBUTTON, BS_DEFPUSHBUTTON, or BS_PUSHLIKE styles do not use the returned brush. Buttons with these styles are always drawn with the default system colors. Drawing push buttons requires several different brushes-face, highlight and shadow-but the WM_CTLCOLORBTN message allows only one brush to be returned. To provide a custom appearance for push buttons, use an owner-drawn button. So, if you need custom background, you have to use owner-draw. Tomasz Sowinski -- http://www.shooltz.com Re: Button background Nick Armstrong16-Sep-01 23:59 Nick Armstrong 16-Sep-01 23:59  Ok, thanks, I suppose I can get around it by altering the bitmap itself to have a white border or something, I'll work on that. The reason I wanted to do it was because some of the bitmaps I was drawing had a grey edge on some sides which was the same colour as the button itself so the border wasn't showing. Thanks anyway, Nick tree template ernst.maurer16-Sep-01 22:31 ernst.maurer 16-Sep-01 22:31  Hi can you advise for me library with tree template class, like STL list or vector Ernst Thanx Re: tree template Christian Graus17-Sep-01 0:12 Christian Graus 17-Sep-01 0:12  map is a balanced, sorted binary tree.

I am writitng a MDI application with CRichEditDoc and CRichEditView classes. Now I want to add some spliter windows so I added like this: Project>add to project>components and controls>visual c++ components>splitter bar" when i run the application the splitter is created, but my childframes windows look very funny. I have 2 vertical scroll bars and 2 horizontal scroll bars, one is the default that comes with CRichEditView, and the second is the one created by the splitter. If I drag the splitter bars somewhere in the middle and then begin typing something in one pane I cannot synchronize the text in all the panes. Also the scroll bars seem not to be working properly. I have posted this topic on several forums, but nobody seems to know the answer! Please give me some help Alex How to detect tap and hold in an edit control in C++ under WinCE ? Sources (Microsoft apps or other) ? Ideas ? 16-Sep-01 21:31 16-Sep-01 21:31  Hello, I think that all is asked in the subject... Indeed I'm working under Windows CE 3.0 more accurately. All Microsoft apps do this to display the standard Copy/Cut/Paste menu, but I really don't understand how it's done. By the way if anyone knows where to find such sources (from Microsoft standard apps packages provided on PocketPC, or from anyone else°, I would really appreciate. Thank you. Please, also send your answers to my email address: francois_pessaux@yahoo.fr --Francois Re: How to detect tap and hold in an edit control in C++ under WinCE ? Sources (Microsoft apps or other) ? Ideas ? Michael P Butler17-Sep-01 2:23 Michael P Butler 17-Sep-01 2:23  According to the CE documentation, the method CWnd::SHRecognizeGesture is used for tap and hold. Have a look at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcemfc/htm/cwnd_197.asp Michael Work with relative paths Eugene Pustovoyt16-Sep-01 19:33 Eugene Pustovoyt 16-Sep-01 19:33  1.
