How to Draw on a ActiveX Control ? chepuri_uk18-Dec-02 19:12 chepuri_uk 18-Dec-02 19:12  I want to draw on the ActiveX Control in Design Mode i.e I placed a ActiveX control on the DialogBox, now i want to draw something on the control . How can i do this ? Any help... Thank you. Re: How to Draw on a ActiveX Control ? Itanium19-Dec-02 0:28 Itanium 19-Dec-02 0:28  I think (not sure) it is not possible to draw on Antivex Control at design time. You can only draw on it after getting its Device Context through Coding. Exporting template class Nilesh K.18-Dec-02 18:01 Nilesh K. 18-Dec-02 18:01  Hi, I'm unable to export a template class from an MFC based dll ! any ideas of how I can do it ? Ciao - Nilesh Re: Exporting template class Christian Graus18-Dec-02 18:06 Christian Graus 18-Dec-02 18:06  Template classes are generated by their template arguments, they are in fact a little class factory. So I reckon you'll have trouble.

That is because a template is a compile time feature. You can force the compiler to generate the code for a particular type of object by simply declaring a global variable of that particular type. But for each type you declare the size of your DLL will grow. There is no way to export a template from a DLL, an retain the power that a template provides. Would it simply be possible for you to distribute the header file with the template class in it instead?

Re: Exporting template class Jeff J18-Dec-02 18:51 Jeff J 18-Dec-02 18:51  I once did what you are trying to do (for export to a non-C++ project), but as Paul mentioned, the benefits of templates are lost. One way is to create a non-templatised wrapper class, and wrap every single method so that it calls the template version. Make sure you inline everything to avoid extra call overhead. If you forget to wrap any methods, the compiler will not generate them at all. Of course, you will have to declare one specific type to be used with the exported class, hence the class will no longer be generic. You can create separate wrapper classes for different types, though your DLL will get rather large. Cheers How to get dimensions of client area without toolbars? Mr.Freeze18-Dec-02 17:52 Mr.Freeze 18-Dec-02 17:52  Hi, How can I get the position and dimension of my client area inside of my CFrameWnd without including the area of docked tool bars or status bars? Thanks Re: How to get dimensions of client area without toolbars? Christian Graus18-Dec-02 18:07 Christian Graus 18-Dec-02 18:07  The docked toolbars sit inside a child window, if you could find that, you could get it's size and subtract it from GetClientRect.

Mr.Freeze18-Dec-02 19:15 Mr.Freeze 18-Dec-02 19:15  Thank you Christian, I tried that, but when the toolBar is docked, it seems that the dimensions obtained with GetClientRect don't match the docking area. Also if I have several toolBars I have to check each single toolBar's status (docked or floating) and then its dimensions. Also what happens if several toolBars dock together on more than one row? Re: How to get dimensions of client area without toolbars? Christian Graus18-Dec-02 19:22 Christian Graus 18-Dec-02 19:22  The child window that holds the toolbars is called a CMiniDockFrameWnd. You need to find those, and grab their dimensions, I think. Or create a View, maximise it, and get IT'S dimensions.

Chris Richardson19-Dec-02 18:23 Chris Richardson 19-Dec-02 18:23  There is a CWnd member called RepositionBars. You can call it like this: CRect a_oRealClientArea( 0, 0, 0, 0 ); pYourFrameWnd->RepositionBars( AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0, CWnd::reposQuery, &a_oRealClientArea, NULL, FALSE ); Chris Richardson Programmers find all sorts of ingenious ways to screw ourselves over. - Tim Smith Re: How to get dimensions of client area without toolbars?

How to activate view in splitter Frame super18-Dec-02 17:17 super 18-Dec-02 17:17  Im developing a Application which looks like the Windows Explorer..Left Side view is a Treeview and righ side view is a Form view. I have a implemented a Find Functionality to search the nodes in the tree wrt to node text in the tree view.The problem is that when i find the particular node I call <br /> treectrl->SelectItem(hItem)<br /> Becos of this OnSelchange event is called and so the coressponding rightside view is displayed..My problem is that to use Find Next again my treeview should be active but that is not the case.So to enable Find next i have to click in treeview to make it active and so that the menu is also enabled... Is there any way to overcome this problem....(ie)After onSelchange event i want again my tree view to be active for further tree operations. cheers, Super ------------------------------------------ Too much of good is bad,mix some evil in it Re: How to activate view in splitter Frame Jeff J18-Dec-02 18:35 Jeff J 18-Dec-02 18:35  My initial thought is that it might be better to avoid activating the right-side at all after searching, rather than having it activate and then deactivate. If you could store a flag value somewhere, that indicates whether a node selection was caused by your find function, you could check it in your OnSelchange event, and avoid activating the right-side there. I would also think you might always want to keep the treeview active while the user works in it, just as you mentioned, since most applications work that way. Sounds like you might need to focus on the OnSelchange event. Cheers Re: How to activate view in splitter Frame super18-Dec-02 19:45 super 18-Dec-02 19:45  Well Ur sugession was Good and it solved the problem of doing Tree operation.. Now i just have a small hiccup... When During Find if i find the correct node then i have to activate the right view...But the problem is Onselchange event is not firing if i call <br /> treectrl->SelectItem(hItem)<br /> after reseting the flag.....Even if i PostMessage(TVN_SELCHANGE) also..No use.. So... any idea cheers, Super ------------------------------------------ Too much of good is bad,mix some evil in it Re: How to activate view in splitter Frame Jeff J19-Dec-02 9:22 Jeff J 19-Dec-02 9:22  When you say you need to "activate" the right view, do you mean you have to fill it with information, or that you have to set the focus on it, or both? I do not know what kind of control(s) you have in the right view, but it should be possible to fill the controls with information, and yet avoid moving the focus to a control in the right view. Re: How to activate view in splitter Frame super19-Dec-02 17:10 super 19-Dec-02 17:10  I want to Display the Right side view For the corresponding Node..So it means I have to Fill the Right side view with the data's.... My class will handle the filling if i can just display the Right side view. Im handling the Filling of data in the InitialUpdate of that View class.. So I just have to fire that OnSelchanged() event in the tree.. cheers, Super ------------------------------------------ Too much of good is bad,mix some evil in it Re: How to activate view in splitter Frame Jeff J19-Dec-02 21:38 Jeff J 19-Dec-02 21:38  Hmmm... I assume you verifed that manually selecting a node with the mouse fires OnSelchanged(), so this is puzzling. Did you check if hItem is valid? Is it possible that OnSelchanged() is being called, but that it is not doing what you need? I also assume you sent the TVN_SELCHANGED message within a WM_NOTIFY message (with the NMTREEVIEW and NMHDR structures filled-in validly), and that it was sent to the window that owns the treeview. Forgive me, but I usually find it is the tiniest mistakes that cause such problems, which are often missed the first time the code is checked. It is hard to guess without seeing the actual code...
