Re: how open a flie with 2 format, (Hex & txt)? zhdleonid2-Dec-02 17:54 zhdleonid 2-Dec-02 17:54  i have seen a code that is class CHexEditCtrl : public CRichEditCtrl it change CString to Hex,but it is in a EditCtrl. i want open a file in a View i can write a class which public CView as --- class CHexEditCtrl : public CRichEditCtrl?? i feel good. Re: how open a flie with 2 format, (Hex & txt)? Nitron3-Dec-02 4:12 Nitron 3-Dec-02 4:12  why not just create a CRichEditCtrl in your view and use that? Then you can have access to all the fun fonts and colors too. - Nitron "Those that say a task is impossible shouldn't interrupt the ones who are doing it." - Chinese Proverb autorun app Jerome Conus2-Dec-02 4:37 Jerome Conus 2-Dec-02 4:37  Hi !!! I'd like to automatically run my app when inserting the CD-Rom (containing my app). My app will be developped with VC++ 6, using the MFC. What I was wondering is : is it possible ? I know that the MFC needs some DLLs, so how can I run my MFC App from the CD-ROM if the required DLLs are not on the local computer ? Linking the MFC statically is enough ? Thanks ! Jerome Re: autorun app Maximilien2-Dec-02 4:51 Maximilien 2-Dec-02 4:51  To resolve the DLL things, your application need to be statically linked with MFC ( if possible ), and if it needs other DLL, they should also be on the CD. You can also do some pre testing, in the autoload thingy on the CD, start another application that checks for DLL's and other things, and then start your application. Or, you can "temporarilly" install the application in a temp directory to run it. Max. Re: autorun app Jawache2-Dec-02 7:01 Jawache 2-Dec-02 7:01  Yep linking statically is fine... Or as long as you place the DLLS the app needs in the same directory as the applcation it elf...

Alvaro Mendez2-Dec-02 11:20 Alvaro Mendez 2-Dec-02 11:20  I don't know of any Timer-related function to do so, but I would probably go with something like GetTickCount to grab the times first at SetWaitableTimer and then at WaitForSingleObject. The max wait time minus the difference of these two should tell you how much time was left. Regards, Alvaro Well done is better than well said. -- Benjamin Franklin (I actually prefer medium-well.) Running 2 builds with VS.NET at the same time Le centriste2-Dec-02 3:45 Le centriste 2-Dec-02 3:45  When I have 2 instances of VS.NET compiling at the same time, one of them makes an access violation error. Is there a way that I can have 2 instances compiling at the same time?

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.
