CStrings in unicode Andrew Stampor21-Jun-01 4:25 Andrew Stampor 21-Jun-01 4:25  I am encountering a problem when I try to append to the end of a CString, specifically in unicode. I can append several times, but it seems that there is some sort of limit to how long a CString can be? After I "+=" up to about 167 characters, it no longer displays the additional characters, yet continues to increase the size when I call GetLength(). Any ideas on what is going on? Re: CStrings in unicode Tomasz Sowinski21-Jun-01 7:06 Tomasz Sowinski 21-Jun-01 7:06  What function are you using for output? Maybe it's ANSI variant and 167th character contains zero? Tomasz Sowinski -- http://www.shooltz.com.pl Re: CStrings in unicode Andrew Stampor21-Jun-01 7:28 Andrew Stampor 21-Jun-01 7:28  I found the problem. Important lesson: make sure you _T() EVERY literal and not just some, or in this case, all but one. Thanks Detecting *any* program launch (not a particular one) 21-Jun-01 4:13 21-Jun-01 4:13  Hi, I previously posted a thread to ask how it is possible to detect that an application is launched. Indeed I don't want to detect that a *particular* program is launched, but to detect that an application (not a specific one) has been launch. This can allow to have a sleeping process that wakes-up only each time an application is launched, do something, then goes back sleeping. This way the "monitoring" process does not consume CPU by always checking if there is something new among the list of the process. --Francois Re: Detecting *any* program launch (not a particular one) Tomasz Sowinski21-Jun-01 6:29 Tomasz Sowinski 21-Jun-01 6:29  Seems that you need a global hook DLL. Windows will map your DLL into memory space of every process in the system, so you'll be able to detect new processes right after launching them - DllMain of hook DLL will receive DLL_PROCESS_ATTACH as dwReason. This should work on Win9X and NT.

I have a diolog box that will ask the user to input the fist file path (c:\MRI001.bmp) and the last file path(c:\MRI0010.bmp), when the user clicks 'OK', I like to have all the files opened from MRI001.bmp to MRI0010.bmp Any ideas how I can do this? I'm a beginner, can someone write me a bit of the code.. Thanks Ehsan Behboudi Re: Opening more than one file with onl one command Tomasz Sowinski21-Jun-01 4:23 Tomasz Sowinski 21-Jun-01 4:23  CWinApp::OpenDocumentFile does this. Just pass the filename as parameter.

But, after this step I would like to catch some cells.value, and after send those value as parameter to a function implement in c++. If anybody know an article or have done this kind of exercise, I will appreciate his help.

In order to use OnNotify, I need to know the ID of the control ( ON_NOTIFY( wNotifyCode, id, memberFxn ) ). I have been unable to find it. Does anyone know how to solve this? Or get around it? Thanks!! Ilan Kleinberger ilan25@hotmail.com NOTE!!! my replay address is spam protected make sure you remove the extra junk, if you want to reply directly. Thanks You're nobody, 'till you've been ignored by a cat. Re: RichEditView Notifications Tomasz Sowinski21-Jun-01 4:01 Tomasz Sowinski 21-Jun-01 4:01  The ID is AFX_IDW_PANE_FIRST if you don't use splitters. However, the best way to handle notifications is in CRichEditView-derived class itself. Just use ON_NOTIFY_REFLECT macro instead of ON_NOTIFY in the message map of your view: ON_NOTIFY_REFLECT(EN_SELCHANGE, OnSelChange) Tomasz Sowinski -- http://www.shooltz.com.pl how to get the VARIANT array of structure having two CPoint variables pathi21-Jun-01 3:10 pathi 21-Jun-01 3:10  Hai I want to put my structure containing two CPoint variables into VARIANT array and assign to DISPPARAMS.I need variant array of this structure.

MFC Dll called from WIN32 Dll sarup21-Jun-01 1:49 sarup 21-Jun-01 1:49  mfc1.dll is a Visual-C++ extension mfc dll that contains 3 classes which use MFC and have a non-mfc external programming interface. mfc1.dll gave no errors during build. winNoMfc.dll is a Visual-C++ WIN32 dll that does not support MFC code within it. It has a dependancy on mfc1.dll. But a function from winNoMfc.dll makes an API call to one of the classes in mfc1.dll. The build of the winNoMfc.dll gives a compile time error "error C2629: unexpected 'class CSoundFile ('" and further such errors even though this class is defined in mfc1.dll. Could you suggest a reason for this. Thanks. Abhay Sarup Re: MFC Dll called from WIN32 Dll Tomasz Sowinski21-Jun-01 2:12 Tomasz Sowinski 21-Jun-01 2:12  C2629 is a syntax error. Check the terminating semicolons in class declarations. I don't think it's a problem with dlls.

Also, you should consider replacing char* with std::string. typedef std::map<char*,int> myMap; myMap m; m.insert(myMap::value_type("aa", 1)); m.insert(std::pair<char*,int>("bb", 2)); Tomasz Sowinski -- http://www.shooltz.com.pl Re: C++ map 21-Jun-01 5:59 21-Jun-01 5:59  typedef std::map<std::string, int=""> MyMap; MyMap map; map["blah"] = 5; int result = map["blah"]; // result = 5 how to pass CTypedPtrList object pathi20-Jun-01 23:37 pathi 20-Jun-01 23:37  Hi I declared CTypedPtrList object in the document class like this CTypedPtrList<cptrlist,cconnector*> m_strokeList; and I want to pass this list to a function in a view by declaring reference CTypedPtrList<cptrlist,cconnector*>& LineList = pDoc->m_strokeList; writeFile(filepath, LineList ); I am getting error that error C2664: 'writeFile' : cannot convert parameter 2 from 'class CTypedPtrList<class cptrlist,class="" cconnector="" *="">' to 'class CTypedPtrList<class cptrlist,class="" cconnector="" *="">' No copy constructor available for class 'CTypedPtrList<class cptrlist,class="" cconnector="" *="">' How can I solve this problem? bhikshapathi_g@semanticspace.com Re: how to pass CTypedPtrList object Tomasz Sowinski21-Jun-01 0:18 Tomasz Sowinski 21-Jun-01 0:18  You're trying to pass CTypedPtrList by value. You should use const reference instead - passing arguments by value is usually much slower and resource consuming (unless you're passing stucts containing only simple types like int or double). Change the declaration of writeFile function to this: void writeFile(CString filepath, const CTypedPtrList & list); Tomasz Sowinski -- http://www.shooltz.com.pl Automatic Browser Plugin Installer Kannan Kalyanaraman20-Jun-01 23:08 Kannan Kalyanaraman 20-Jun-01 23:08  I need to write an automatic plugin installer for browsers(Both IE and Netscape) plugin.
