Re: Why this is happening? -- Why this is capturing screen image instead of ClientDC JHAKAS1-Jun-04 19:34 JHAKAS 1-Jun-04 19:34  Please follow the following link for better idea http://www.codeguru.com/forum/showthread.php?s=d09323bd39f2dd0a942e34fe1155af42&threadid=296795 My main aim is to draw the content to view such that when user wants he can save the same to image file. Thats it? What i tried that i drawn completely into the ClientDc and at the end (see first post) i am making the memory device context and then storing teh content to the image file. Well but it seems that MemDC is taking the complete Mainwindow instead of the required clientdc.

COM controls security Imtiaz Murtaza31-May-04 1:47 Imtiaz Murtaza 31-May-04 1:47  Dear Friends, Suppose i got an ActiveX control (or any COM dll). I am distributing it will by application. Now the problem is that anyone can utilize that dll or OCX. I want to prevent others to use my OCX and dlls. How can i ensure the security of my COM controls so that no one else can use it. Imtiaz Re: COM controls security Sumit Kapoor31-May-04 4:05 Sumit Kapoor 31-May-04 4:05  HI One Idea is... Create Time: in OCX or DLL define a variable with some value let XXXX & check at load time. if false then exit. On Use time: at contructor or on_load set that value as XXXX(as u set that in coding u know that..) & then start application.... OK!

Trying to use it gives me an access violation as expected. All parameters passed in to MapViewOfFile seems to be fine. Anyone has faced the same problem before ? Thanks Re: MapViewOfFile() Anthony_Yio31-May-04 1:30 Anthony_Yio 31-May-04 1:30  (From MSDN) Reading from or writing to a file view can cause an exception. For example, accessing a mapped file that resides on a remote server can generate an exception if the connection to the server is lost. Exceptions can also occur because of a full disk, because the file is shared and a different process has locked a byte range, or because of an underlying device failure or memory allocation failure. To guard against exceptions due to input and output (I/O) errors, all attempts to access memory mapped files should be wrapped in structured exception handlers. Sonork 100.41263:Anthony_Yio Re: MapViewOfFile() Roger Allen1-Jun-04 5:07 Roger Allen 1-Jun-04 5:07  Check the last parameter to CreateFileMapping as I think this needs to be a wide character string otherwise you get a GPF then or later.

Indrawati30-May-04 21:33 Indrawati 30-May-04 21:33  Hi I have one quick question here: is it possible to insert a class with private copy constructor and assignment operator into a Visual C++ vector STL? How about other STL implementations? I have tried it on VC++ 6.0, and it does not seem to be possible. Or maybe there's another not-so-straightforward way to do it? Thanks! Re: Vector STL - insert class with private copy constructor and assignment operator? markkuk30-May-04 21:53 markkuk 30-May-04 21:53  You can't use such objects with any standard-conforming implementation of the STL. STL containers require that the elements stored in them are copyable by a copy constructor and assignable by the assignment operator. Re: Vector STL - insert class with private copy constructor and assignment operator? Jörgen Sigvardsson31-May-04 5:31 Jörgen Sigvardsson 31-May-04 5:31  No, not by value. In fact, by making the copy constructor and assignment operator private, you are declaring that you cannot copy objects of this type, hence there is no container which can store them by value. You need to store pointers to them. -- Booohoo! It is possible ?
