• Veo Binary Reading from a file

  Interesting! //Convert 64bits of raw binary data in a character array to a 64-bit unsigned integer // //data: array containing the required data //index: index into the array that the integer data starts //returns: the converted integer value starting at index // unsigned long long CharArray2Int64(char *data, int index) { return *(reinterpret_cast<unsigned long long *>(data+index)); } Sorry about this but could you explain again, in caveman pictographs, what reinterpret_cast does James ================================================================= What I am trying to do is to give each possibility of 64 bit a unique reference number. And the best way to do that is convert every 64 bit into ...Show All

• NetPochi Bitmap pixel interpolation

  Hello, I am making small 24bpp bitmap images (say, 20x20 pixels). I use the lockbits and all that to do it because it is faster. After I amke the image I display it in a picture box, the pixels are not solid colours...they interploate into one another which I guess is to smooth out larger images and make them look better. But I actually want fully pixelated images with no interpolation. If I save the image and look at it in paint instead, the image IS pixelated and there is no interpolation, no blending. So what is going on here How do I get the picture box to display the small image fully pixelated Thanks a lot! Joe This code would help you CDC* pDC = GetDC(); CBitmap bitmap; ...Show All

• chris fitzmartin Getting garbage setting dialog box text

  Hi Folks; I'm trying to set the text of a dialog box with SetDlgItemText. As an example I'm trying: SetDlgItemText(hwnd, IDC_F1, "Some text"); where IDC_F1 is defined as the ID for an edit box. What I'm getting is just garbage and I thought maybe it was my font but I've set it do Courier New, size 8 which I thought was pretty standard. Maybe someone could shed some light on my sitation. Yes, of course, that's a good point. But just want to point that CString is also a template class and is not MFC specific (though it's exported from MFCXX.dll).

• Zokkan Windows forms help

  Hello everybody i wonder if you can fill a hole in my understanding of programming windows. I am trying to develop a very basic windows forms application. I have a class called class1 and another called game. It is my understanding that the autogenerated form1.h is also a class. Maybe this is because i don't understand. Anyway from game i can declare a pointer of type class1 and access class1's data members, functions etc from a function inside game. I can also declare a pointer of type form1. However when i come to access form1's data members using this pointer it won't let me alter them it just says: error C2227: left of '->richtextbox1' must point to class/struct/union/generic typ Here is the code: //game.h #pragma once cla ...Show All

• Softwhere How can I check security vulnerabilities with VC8

  I am developing C++ program with VC8. I know VC8 can check security vulnerablitities. So could someone tell me how can I do that. Is there any additional tool can do that job either Buffer overflow checking (/GS flag) is enabled by default under VS 2005. /RTCsu gives you extra runtime error checking. Visual Studio 2005, Team System edition, can also do static analysis of programs to warn you about vulnerabilities during compile time. The menu item is Build:Project Only:Run Code Analysis (/analyze flag). As an example, it warns on the following: void test( char * src) { char dst[10]; strcpy( dst, src ); } I don't know what you mean, that VC8 can check ...Show All

• Bo Yu msvcr80d.dll not found

  I've created a simple Win32 console application. When I try to debug it, I get the message:  "This application has failed to start because MSVCR80D.dll was not found. Re-installing the application may fix the problem." The Release version runs fine. Any idea as to what the problem could be Thanks, Jonny OK. I had the same problem with the Express Beta, now I see it was not fixed in the released version. The bug is very simple: the manifest resource file "Debug\xyz.exe.embed.manifest.res" is generated BEFORE its source file. Just check the build log. Removing the .res file and rebuilding cures the problem. PS. I wonder if building on a NTFS vs. FAT partition affects this. ...Show All

• ghw123 Borland C++ V4 and Visual C++

  I have been asked to upgrade an old system. The person in question has the files which were created in Borland C++ V4. However i do not have Borland C++, is there any version of Visual C++ that can read the files or will i need to source a copy of Borland C++ What files That makes sense. I did not realize that that is what you were asking but it seems to be a valid question. I don't know of a way for VC to read the Borland project files and I doubt that such a thing exists. If it does then the quickest way to find it is to search MSDN for Borland. You could search using the two words Borland and project. You are more likely to get help in a forum or newsgroup that does not specialize in VC a ...Show All

• TheQuietShadow MFC Controls in Managed C++... Help!

  Hi, A while back I designed a couple of CEdit derived MFC controls in VC++ 6.0, but our company recently made the upgrade to Visual Studio 2005. I need to re-use these controls from C# and VB environments, but would like to use the existing code rather than re-write every control. These controls will be contained in a managed C++ DLL. I've been trying to create a System::Windows::Forms::Control object which wraps my CEdit control, and passes Windows messages through to the control by overriding the DefWinProc function, but for some reason the control is not painting/drawing.
