Re: Check boxes in CTreeCtrl Tomasz Sowinski3-May-01 23:42 Tomasz Sowinski 3-May-01 23:42  The solution is quite funny. Here's what I found in the "Tree View Control Window Styles" at MSDN: "TVS_CHECKBOXES: ... If you want to use this style, you must set the TVS_CHECKBOXES style with SetWindowLong after you create the treeview control, and before you populate the tree. Otherwise, the checkboxes might appear unchecked, depending on timing issues." To solve the problem, you have to: (1) clear the 'check boxes' option in the tree control properties in dialog editor (2) programatically set the style after the window is created and before items are inserted: m_Tree.ModifyStyle(0, TVS_CHECKBOXES); for (...) { m_Tree.InsertItem(...); m_Tree.SetCheck(...); } (2) is not enough (at least on my W2K box) - you can't have your tree control created with TVS_CHECKBOXES style.

Steve Do I HAVE to install MDAC for Office 2000? Matt Philmon2-May-01 12:02 Matt Philmon 2-May-01 12:02  I have to continue to support an old MFC-based application that still uses ODBC to connect to an Access 97 database. (We're rewriting the whole thing as a web application but until it's done we have to continue to add features and support...) Anyway, the database is updated each time we release a new patch to the system (upgrade). The upgrades come down from the web, so we TRY to be kind on the size of the patch. Continuing to update an Access 97 is a major pain since pretty much everyone has moved on to 2000. However, if I convert the database to Office 2000, the database won't load through ODBC calls without installing at least MDAC 2.5. The patch is a single patch that supports Windows 95/98/ME/NT/2000 so (using InstallShield) the MDAC 2.5 object bloats the 4.5 MB patch to 13.5 MB (I suppose because of the cross-platform support). Is there any minimal things I can do make this work without having to install the entire MDAC update? Problem With Auto Complet.

The NCB will be recreated when you open the workspace again. --Mike-- http://home.inreach.com/mdunn/ The Signature, back by popular demand: Buffy. Pajamas. Getting hwnd of a child window Rukhsar2-May-01 8:03 Rukhsar 2-May-01 8:03  Does anyone know how to get a handle to a mdi child window WITHOUT MAKING IT ACTIVE? Take a look at this code: CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd; CMDIChildWnd *pChild; CMyView *pView; CMyDoc *doc; CString findWindow = "My1";// this is the title of the window i want to find while(TRUE){ pChild = (CMDIChildWnd *)pFrame->GetActiveFrame(); pView = CMyView *) pChild->GetActiveView(); doc = (CMyDoc *) pView->GetDocument(); CString str; str = doc->GetTitle(); //if screen title is the same as node text, return. if(findWindow.Compare(str) == 0) return TRUE; pFrame->MDINext(); } This code works great, it will find the child window that has the same title as the one i pass to it. however, it will make all the open windows active when, method MDINext() will go to next child and will activate that child, i don't want that, i want it to search through all window without activating them. I used LockWindowUpdate on pFrame after calling MDINext() but it did not work, any idea?

I am trying to make a program that I am developing bullet proof. What I need to do is prevent a user to use the "control-alt-delete" button to kill a program. He needs to gracely terminate the program by using the programs own termination buttons. Does anybody know how to accomplish this? The program shows up in the taskmanager window. If this is not possible is there a hack to keep a program out of the taskmanager and at the same time keep it running? This program runs under win9x,ME and 2000. Is there also a possibility if they do get to the program that is running and when they kill it ungracefully that I can make their machine hang? Thanks in advance, Raymond Raymond Bentoera Cybergate Interactive Re: Keeping process out of task manager Tomasz Sowinski2-May-01 23:19 Tomasz Sowinski 2-May-01 23:19  Well, as a user, I definitely don't like programs that can't be killed. And making somebody's machine hang after killing the process seems to be the activity of worm/virus. Tomasz Sowinski http://www.shooltz.com.pl Re: Keeping process out of task manager yamini3-May-01 0:30 yamini 3-May-01 0:30  Hi, My problem is similar to the one replied .It is related to process hiding in the TaskManager .I have a parent process running .The child process of this parent should not be able to see it's parent process in the TaskManager !But the aprent process will be runing . I want to show the parent when the child process is killed .How can I do it ? Thanx in advance for the help ! Y.Yamini Devi Re: Keeping process out of task manager Daníel B. Sigurgeirsson4-May-01 3:39 Daníel B. Sigurgeirsson 4-May-01 3:39  As a programmer I do not like users trying to cheat programs that I have developed. That is why I need to find a way to discourage these power users from cheating the software. Ok, let's try to explore a nicer way of discouraging the user to ungracefully kill the program. The idea of the software is not to disable the user from running the software. Because the software has its own way of closing it. It has its own close button. But the problem is that there is a way of cheating the program by using 'cntrl-alt-delete'. I am implementing the software now to run a s a service in win 95, 98 and ME. But I have a problem with windows 2000. You can see all the services that are running. Also I would like to explore another way of making this program bulletproof. The program I am writing is a free Internet Dialer program where the user gets a banner window that he should not be able to close if he is surfing online using this software. Another problem might be third party software like "system properties" that will unhide programs from the taskbar. That is why I would like to explore other ways of making this program bulletproof. Do you know of anyway this program can disconnect the user if it uses 'cntrl-alt-delete' instead of closing the program using its closing button. The software uses windows dialup networking to dial. If somebody knows a way how to make this program bulletproof please send me your remarks. Thanks in advance, Raymond Bentoera Cybergate Interactive Re: Keeping process out of task manager Tomasz Sowinski4-May-01 3:55 Tomasz Sowinski 4-May-01 3:55  You can't kill the service processes from Task Manager in Win2000 - you'll get the 'Access is denied' message. Tomasz Sowinski http://www.shooltz.com.pl Re: Keeping process out of task manager Tomasz Sowinski4-May-01 4:07 Tomasz Sowinski 4-May-01 4:07  > The program I am writing is a free Internet Dialer program where > the user gets a banner window that he should not be able to close > if he is surfing online using this software. So where's the problem? Just display a msgbox saying "You'll be disconnected if the banner window is closed. Close anyway?" Tomasz Sowinski http://www.shooltz.com.pl Re: Keeping process out of task manager Daníel B. Sigurgeirsson4-May-01 4:50 Daníel B. Sigurgeirsson 4-May-01 4:50  I have implemented that message window already when the users click on the close button of the window. But that is not the problem. The problem is that at the moment the users can use 'cntrl-alt-delete' to kill the banner window. This way the banner window will disappear and the connection stays. So the user will be able to keep using the connection illigitimately Do you know of a way to also kill the connection when the user uses the 'cntrl-alt-delete' buttons. Or do you know a way to implement this? Thanks in advance, Raymond Bentoera Cybergate Interactive Re: Keeping process out of task manager Tomasz Sowinski4-May-01 10:06 Tomasz Sowinski 4-May-01 10:06  I'd periodically (once per minute?) check in dialer process if window is still open. If no banner window is open, the connection is terminated. Tomasz Sowinski http://www.shooltz.com.pl Re: Keeping process out of task manager Daníel B. Sigurgeirsson7-May-01 2:48 Daníel B. Sigurgeirsson 7-May-01 2:48  Yes, but I will need to have a seperate process check this out since if I make it part of the dialer window If it is killed it wont be able to check if the dialer window is still open. Thanks I will give this a try. Raymond. Raymond Bentoera Cybergate Interactive Trying to make a program bulletproof Daníel B. Sigurgeirsson2-May-01 6:39 Daníel B.

When i create multiple windows via the CWnd::Create function it doesnt show the active window. Normall if a window is selected doesnt it darken to indicate it has focus. Not matter which child window i select they all keep the lighter, not in focus, colour. If any one could help or shed light on the subject i'd be grateful.

I achived this thru', using paths and then converting paths to region fn. Now i need to fill these each characters with Gradiant filling which has to use the shape of the Text. ie, i need a procedure to seperate each character from the Text into a individual region and fill them with the Gradiant , which actually uses the shape of those character. How to achive this. Pl. Help me. I've a sample image of it. But i don't know how i can attach that image with this post. Advance ThanX, Subbi Re: Gradiant Color Filling in Irregular Shape 2-May-01 6:10 2-May-01 6:10  The easiest solution I can come to think of is alpha-blending that text with a gradient bitmap and the trans-blit it onto the final surface.
