MFC overrides operator new and if it fails, it throws a CMemoryException. So you need to wrap your allocations in try/catch blocks and handle that exception. --Mike-- Just released - RightClick-Encrypt v1.4 - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm Re: finally dealing with 'new' ns17-Sep-02 3:19 ns 17-Sep-02 3:19  So if I already have a try-catch for COM errors in my code and I do a new in the try, I should add another catch? Like catch(CMemoryException *e) { } Is the e coming in from the system? Thanks, ns Re: finally dealing with 'new' Michael Dunn17-Sep-02 5:27 Michael Dunn 17-Sep-02 5:27  Right, the CMemoryException object is created by MFC. --Mike-- Just released - RightClick-Encrypt v1.4 - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm How to insert a number of Icons into a project? chen12-Sep-02 5:47 chen 12-Sep-02 5:47  Hi, I have a number of Icons downloaded from the internet.

Each "sub-folder" must be dockable and the folders must be "foldable" (like in Visio 2000). Does anyone have any idea ... ? Yeali Re: Visio 2000 Style Dockable windows Anonymous12-Sep-02 5:44 Anonymous 12-Sep-02 5:44  What you are looking for is present on code project itself! go to libraries and projects section and download the MFC GUI Extesion library by Fransico Campos. This one's got an excellent Visio component. Statistics Package David Day12-Sep-02 5:18 David Day 12-Sep-02 5:18  Does anyone know of a good statistics package for C++ (preferably free/OpenSource). I'm translating a Microsoft Excel workbook full of macros into a stand-alone MFC App, and I'm having trouble finding an adequate solution to the Excel functions of LOGINV, BETAINV, etc. Any help is always greatly appreciated. Can someone crack this problem? I can't... Tommy Svensson12-Sep-02 4:58 Tommy Svensson 12-Sep-02 4:58  Hi everybody, I have developed an IE extension that will popup an HTML div layer with lots of information once I move the mouse cursor over a word/string in a web page document. Now, this is restricted to only work in IE. I want the same functionality but system wide. I know there is software that can do this; that is, point the mouse on ANY string (besides the ones that are images) on the screen and voila, a nice little box appear next to the word with translations and other nice information about the word. My question: How can I retrieve the string beneath the mouse pointer, no matter where and in which application the mouse cursor is placed...? I've heard of some OCR programs that can do this but I don't want that now; maybe as a next step to implement popups on images as well. Please, if you do know anything about this, don't hesitate to mail!!! Thx!!! /Tommy Re: Can someone crack this problem? I can't... benjymous12-Sep-02 5:24 benjymous 12-Sep-02 5:24  I'm afraid that OCR is going to be your only answer if you want *any* text, since the text gets rendered by the App to screen, and therefore may not even exist as a literal string in memory when you try and grab it. It might be possible to somehow add a system hook to grab text that can be copied to the clipboard, but that's only going to be a tiny subset of the text on screen -- Help me! I'm turning into a grapefruit! Re: Can someone crack this problem? I can't... Andreas Saurwein12-Sep-02 5:57 Andreas Saurwein 12-Sep-02 5:57  Look at the Active Accessibility API (IAccessible etc) for a good start. Its not easy to use, but provides a good lot more information on screen items. int x=1, y=5; x^=y^=x^=y; // whats the content of x and y now? <a href="http://www.codeproject.com/tips/StupidXORTrick.asp" target="_blank">ClickHereForHelp();</a> MAX_PATH defined as? ns12-Sep-02 5:01 ns 12-Sep-02 5:01  Is this counted as a number of bytes? Or the number of characters? Where is it defined so that I can find its value? Thanks, ns Re: MAX_PATH defined as? Chris Losinger12-Sep-02 5:04 Chris Losinger 12-Sep-02 5:04  #define MAX_PATH 260 in windef.h (try searching your VC++ installation folder!) it's used as the number of elements in a character array. -c Greenspun's Tenth Rule of Programming: "Any sufficiently complicated C or Fortran program contains an ad-hoc, informally-specified bug-ridden slow implementation of half of Common Lisp." Re: MAX_PATH defined as? ns12-Sep-02 5:19 ns 12-Sep-02 5:19  Thanks. I'll remember that. I just tried the msdn and it didnt say much. One thing: do you think its big enough to hold an random path to a file on some users machine, in general? I'm using filecopy and will know the destination and source interactively, so cant predict pathlength. Would you error trap this just in case, Or is it safe to assume that paths will fit into 260? I'm not sure what the smart thing to do is, in this case... thanks, ns Re: MAX_PATH defined as? Chris Losinger12-Sep-02 5:20 Chris Losinger 12-Sep-02 5:20  yes, i'd make sure things fit. (measure strings first). and when at all possible, i try to use dynamic strings like CString, std::string, etc. and i only measure when i run up against a non-dynamic string (char buf[MAX_PATH]). -c Greenspun's Tenth Rule of Programming: "Any sufficiently complicated C or Fortran program contains an ad-hoc, informally-specified bug-ridden slow implementation of half of Common Lisp." Re: MAX_PATH defined as? Ravi Bhavnani12-Sep-02 5:56 Ravi Bhavnani 12-Sep-02 5:56  Actually, it's _MAX_PATH, which is the OS specific max length of a fully qualified filespec. If my memory serves me right, it's defined in stdlib.h. /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com Re: MAX_PATH defined as? ns12-Sep-02 8:26 ns 12-Sep-02 8:26  Thanks! I'm trying to do CopyFile and apparently need the unicode version which allows >MAX_PATH for file path (from MSDN). But I cant find any info on this unicode version in MSDN, or an example of its usage. My current workaround is not to copy if filepath doesnt fit in max_path but thats not very friendly.... Popup menu 12-Sep-02 4:32 12-Sep-02 4:32  Hi, In a MFC app I have a menu like : MENU-> Show Hide (...) Names-> One Two Exit Names is added dynamically with the following code : CMenu namesmenu; namesmenu.CreatePopupMenu(); submenu -> InsertMenu(1, MF_POPUP, (UINT_PTR)namesmenu.m_hMenu, "Names"); and filled with : namesmenu.AppendMenu(MF_STRING, ID_NAMES + i, strNames[i]); ok, now in my CDialog derived class, to know when an added option (One, Two, etc) is selected, I have : BOOL CReminditDlg::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo) { if (pHandlerInfo == NULL && nCode == CN_COMMAND) { /* here I need to know how many menu items had been added, and I don't know how to do this ! */ } return CDocument::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo); } Thanks if anyone can help me ! Re: Popup menu Anonymous12-Sep-02 4:35 Anonymous 12-Sep-02 4:35  In other words, how to access a submenu of a submenu ? Re: Popup menu Tomasz Sowinski12-Sep-02 4:47 Tomasz Sowinski 12-Sep-02 4:47  I'm not quite sure why are you using OnCmdMsg. If you want to handle the range of command IDs, just use ON_COMMAND_RANGE in your message map.

Anyway, how to access to the "Name" submenu ? Re: Popup menu Anonymous12-Sep-02 5:10 Anonymous 12-Sep-02 5:10  Ok I don't use ON_COMMAND_RANGE because I don't know in advance how many items I will add... Re: Popup menu Tomasz Sowinski12-Sep-02 5:19 Tomasz Sowinski 12-Sep-02 5:19  But there's upper limit. You won't be adding 10000 items for sure. Tomasz Sowinski -- http://www.shooltz.com To some its a six-pack, to me it's a support group Re: Popup menu Anonymous12-Sep-02 5:31 Anonymous 12-Sep-02 5:31  Ok you're right ;o) But this isn't the problem : I try to access to the dynamically created menu : CMenu menu; menu.LoadMenu(ID_MENU); // load the menu CMenu* submenu = menu.GetSubMenu(1); CMenu* namesmenu = submenu.GetSubMenu(...); int nItem = namesmenu.GetMenuItemCount(); but it doesn't work... Re: Popup menu Tomasz Sowinski12-Sep-02 5:39 Tomasz Sowinski 12-Sep-02 5:39  Have no idea how your menu looks like. Check if 'submenu' points is non-NULL. If it points to some CMenu object, then check if it's actually the submenu you're looking for - use GetMenuItemCount/GetMenuString. If you get this right, proceed to namesmenu. Tomasz Sowinski -- http://www.shooltz.com To some its a six-pack, to me it's a support group pointer/handle brianwelsch12-Sep-02 3:55 brianwelsch 12-Sep-02 3:55  Is there actually a difference between a pointer and a handle, or is it just the context of what you happen to be talking about?
