When does the Second Edition of Inside C# get released, Amazon.co.uk is still only listing the first edition Michael Communication is the first step towards enlightenment. Re: Managed C++ books Tom Archer28-Apr-02 4:12 Tom Archer 28-Apr-02 4:12  I've never seen my reviews over there. The "Petzold of C#"? That might be just a bit of hyperbole I'll take it though!! Anwyay, I have no idea why it's not listed on the UK Amazon. It should be in stores this week and I know that US Amazon is shipping it now. I'll ask the publisher tomorrow.

Re: how to create avi file alex.barylski27-Apr-02 11:53 alex.barylski 27-Apr-02 11:53  avi I thought was audio video something (interchange maybe). animated gif's are similar but no sound... Theres tons of free tools that will create AVI's for you from bitmaps and such... Maybe Flash has a tool to convert *.swf files to avi's Check out www.wotsit.org for full details on the AVI file structure.

I am working on a multiview program (two views). The design is done; however, I just found out I cannot cast GetActiveView() in main to any view I want. For example, let say I am in main and the active view is View#1, but I want to send a message or call a function in View#2. How do you access *any* view, active or inactive, from main? Thanks, Kuphryn Re: Access a Specific View in MainFrame :: MFC Tom Archer27-Apr-02 10:05 Tom Archer 27-Apr-02 10:05  Like many things in MFC, there are many answers here and it comes down to personal choice and your system design: 1) You could call the document's UpdateAllViews function and pass the desired message & data that way. 2) You could store the view pointers in a central place (such as the app object or the mainframe object) and then call a member functions to either send the data from that main object or to return the pointer so that you could then directly call the view's member functions In situations like these there is no right or wrong way although I typically like to use the built in UpdateAllViews method.

Re: Access a Specific View in MainFrame :: MFC Michael P Butler27-Apr-02 10:11 Michael P Butler 27-Apr-02 10:11  I tend to store pointers to each view in my CWinApp derived class. I'm not sure it is the best way, but it works well for me as I tend to have multiple views connected to just one document class. Michael Communication is the first step towards enlightenment. Re: Try to change your function location! Masaaki Onishi27-Apr-02 10:28 Masaaki Onishi 27-Apr-02 10:28  Hello, the codegurus around the world.;) Even though I don't know your code in detail, I guess that you will change the location of your function in View2. If the some funtions can share between View2 and View1, try to put these functions to the other classes like Doc, Frame or WinApp. This is mainly because if view2 doesn't get the current focus, we don't need to send the message or call the function. If the view2 gets the input focus, we should restore these data to update. Or anyone has better idea? Please, don't send me your email about your questions directly. Have a nice day!

Here is the solution for a splitter design. ----- CMyView2 *pView = reinterpret_cast<cmyview2 *="">(m_wndSplitter.GetPane(1, 0)); pView->SendMessage(WM_USER_TEST, 0, 0); return 0; ----- Thanks to LordShade of GameDev for for the pointer. Kuphryn Re: Solution Tom Archer27-Apr-02 11:15 Tom Archer 27-Apr-02 11:15  You didn't mention that you're using a splitter. In that case, the views are created in the mainframe and can be accessed through the mainframe's splitter window member variable.

Re: Solution valikac27-Apr-02 11:47 valikac 27-Apr-02 11:47  Thanks. I did not think that the splitter window would affect it. Kuphryn Re: Solution Tom Archer27-Apr-02 11:53 Tom Archer 27-Apr-02 11:53  No problem. The effect it would have on anyone's answer is that with a splitter, you already have a "built-in" place to get the views (the CMainFrame::m_wndSplitter). Anyway, no worries. I'm glad you got your code to work. Just remember to be a bit more detailed when asking for help as it aids others in getting you the response you need.

And if message isnt WM_LBUTTONDOWN send message to child window. (child window never conceive WM_LBUTTONDOWN but user click on it - without WS_DISABLE) Wiizi Re: Messages Michael P Butler27-Apr-02 10:13 Michael P Butler 27-Apr-02 10:13  Have a look at PreTranslateMessage, I think it will do what you are wanting. Michael Communication is the first step towards enlightenment. Re: Messages Tom Archer27-Apr-02 11:10 Tom Archer 27-Apr-02 11:10  You need to override the WindowProc function. Here's an example of doing that where I'm not allowing the OK button's normal processing to continue (by returning FALSE from the function). if (message == WM_COMMAND && LOWORD(wParam) == IDOK) { TRACE("I got this click and I'm not allowing it to process!!"); return FALSE; } If I want the button to handle it's message, then I simply return the return value of the base class' WindowProc function: return CDialog::WindowProc(message, wParam, lParam); Also, you can use the hwnd of the control (I used the resource id) by referencing the lParam argument (instead of the low byte of the wParam).

Adding own things to the explorer browser <k>Andreas Hoheisel27-Apr-02 8:10 <k>Andreas Hoheisel 27-Apr-02 8:10  I worte a litte command line programm where i can access ReiserFS Partitions. Now i want add this capability to the explorer. So anyone knows if its possible to add for eg. a new drive in the explorer window... Thanks Re: Adding own things to the explorer browser Michael Dunn27-Apr-02 8:39 Michael Dunn 27-Apr-02 8:39  There are two approaches you can take. One is to write a device driver, which can be assigned a drive letter. The other is to write a namespace extension which can add a folder under My Computer (along side Control Panel). I have a tutorial on namespace extensions in the Shell section. --Mike-- Buy me stuff! Like the Google toolbar? Then check out UltraBar, with more features & customizable search engines!

Properties of ActiveX (and control) Wizard_0127-Apr-02 6:43 Wizard_01 27-Apr-02 6:43  Hi Do you know how can I get array or supported properties of control at runtime ? Wiizi Right-aligning with WS_EX_RTLREADING Oz Ben Eliezer27-Apr-02 6:28 Oz Ben Eliezer 27-Apr-02 6:28  Hey all. I use CreateWindowEx to create a Rich Edit Control. I use WS_EX_RIGHT | WS_EX_RTLREADING to make it right-aligned on a Hebrew OS. It works well on Windows 2000, but on a clean installation of Win98 Heb-enabled, the content of the Rich Edit Control is left-aligned. On a not-so-clean installation of Win98 (which has Visual Studio, Office, etc.) - it displays correctly. The problem is not with comctl32.dll - copying that file from the "good" win98 to the "bad" win98 doesn't solve it. Any ideas??
