Calculate the size of CString object X204031-Jul-04 2:05 X2040 31-Jul-04 2:05  how can i calculate the acctuale size of a certain CString object in bytes Re: Calculate the size of CString object bikram singh31-Jul-04 2:44 bikram singh 31-Jul-04 2:44  ?? Is this kinda what u mean: CString m = "a"; int size = sizeof(m) + m.GetLength() + 1; //1 for null size will contain '6' bytes... (4 for the internal pointer it maintains, + 1 for the "a", plus 1 for the null byte...) Bikram Singh Re: Calculate the size of CString object Ravi Bhavnani31-Jul-04 3:08 Ravi Bhavnani 31-Jul-04 3:08  CStrings are unicode objects (each character occupied 2 bytes). Also, as I understand it, the size of a CString object is fixed, regardless of the length of the string, since memory required to store the string is obtained from the heap. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: Calculate the size of CString object bikram singh31-Jul-04 14:47 bikram singh 31-Jul-04 14:47  Ravi Bhavnani wrote: CStrings are unicode objects (each character occupied 2 bytes). Possibly, but only with the UNICODE directive turned on i should think..

But, Abdu's question was a bit vague ("actual size" was unclear to me, so i took a wild guess).

Yes, you're quite correct. I was hasty in replying and am also guilty (?) of always supporting Unicode. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: Calculate the size of CString object Anonymous31-Jul-04 3:12 Anonymous 31-Jul-04 3:12  Works for both ansi, unicode. CString s = _T("Hello"); int bytes = (s.GetLength() + 1) * sizeof(TCHAR); Re: Calculate the size of CString object peterchen31-Jul-04 7:16 peterchen 31-Jul-04 7:16  What do you need the size for? we are here to help each other get through this thing, whatever it is Vonnegut jr. sighist || Agile Programming | doxygen Re: Calculate the size of CString object X204031-Jul-04 9:27 X2040 31-Jul-04 9:27  iam making a program like Norton ghost i want to save the files and their paths on another partition as a backup do you have any better idea to make a program like Norton Ghost? do know any function that copy a complete partition into backup disk? Re: Calculate the size of CString object peterchen31-Jul-04 9:46 peterchen 31-Jul-04 9:46  For your purpose, the others said it already, it's (s.GetLength()+1)*sizeof(TCHAR). (however, you cannot simply pass the address of CString itself to a binary reader/writer) we are here to help each other get through this thing, whatever it is Vonnegut jr. sighist || Agile Programming | doxygen drive explor X204031-Jul-04 12:11 X2040 31-Jul-04 12:11  is there any way or functions that can copy data as a low level binary from the drive to another location or drive (Norton Ghost like) . ex: copy files and directories with out getting the path of each file and copy it to the new location i mean to get binary data from the drive direct and copy it NT: CreateFile/ReadFile; Win9x: VxD or 16-bit DLL bikram singh31-Jul-04 16:05 bikram singh 31-Jul-04 16:05  Under WinNT+, you can use CreateFile("\\\\.\\C:") to open read-only access to any disk drive (hdd or fdd), and if you know the FAT/other file system format, you can easily read data using ReadFile(). On Win9x, you can read floppies using VxD services (it's there in MSDN as an example, but i dont remember where). For reading HDD's you need to either use 16-bit code (to call BIOS functions), or write a VxD.

I want my application to have some fancy 3D accelerated graphics. Is it possible in windowed mode to have per pixel alpha blending with the windows underneath in real time? Joel Holdsworth Re: Direct3D/OpenGL question Antti Keskinen31-Jul-04 12:37 Antti Keskinen 31-Jul-04 12:37  The DirectX C++ Documentation doesn't speak for or against this subject. Apparently the only reasonable way to know for sure is to test. The Direct3D scenes are drawn in the backbuffer and then blitted to the target area. As the backbuffer can be initialized so that it's handled like a full-screen scene (although only a part of it can be blitted), then I believe all Direct3D effects are available in windowed mode as well. -Antti Keskinen ---------------------------------------------- The definition of impossible is strictly dependant on what we think is possible. can i trigger an event to C# app in a C++ Win32 DLL ? fu031-Jul-04 1:44 fu0 31-Jul-04 1:44  i m writting a C++ Win32 DLL which is called by a C# application. i want the DLL can trigger an event to the Calling C# app after some operations which might like the Win MSG mechanism: The DLL send a message to the C# app and the C# app handle the msg. the C# use the EventHandle/EventArgs on this issue.
