This article shows you how to develop a simple but effective port scanner for Win32, using a self written socket classes (not the CSocket which comes with MFC) and a small framework based on the […]

Visual Studio .Net creates assemblies. An assembly is a combination of metadata and a portable executable. Unlike applications built in earlier versions of Visual Studio, Visual Studio .Net combines extra information necessary to describe the executable. This extra information is the metadata, and is the technical feature that supports xcopy deployment of Visual Basic .Net […]

The CString class does have a function Format(), which writes formated data into the CString object (just like sprintf() formats data into a character array). There is no equivalent to the sscanf() function. This is quite annoying, […]

This article was contributed by Ed. Environment: NT, will work on 9x with modification. You’ll notice that in most of the .zip files you download with code from sites like codeguru include a .ncb file.

Environment: C#, VC++, .NET The first thing you should understanind is why you would want to use unmanaged code. There are possibly two reasons to call unmanaged code: You want to reuse your code which is already written in an unmanaged environment e.g. VC 6.0 You want to perform some low level work. ( i.e. […]

  Environment: VC++ 6.0 One friend asks me how to draw a curve with a couple of mouse clicking. I know there is way called “cubic spline” to draw the curve based on the control points. I search through the internet, try to find out a piece of existing code. Unfortunately, though there are plenty […]

This article will show you how to add a Toolbar button in CFileDialog’s Toolbar. Here is the sample code: CONST LONG ID_NEW_BUTTON = 40790L; // Command ID of new // Toolbar button. class CFileDialogEx : public CFileDialog { DECLARE_DYNAMIC(CFileDialogEx) public: CFileDialogEx(BOOL bOpenFileDialog, // TRUE for FileOpen, // FALSE for FileSaveAs LPCTSTR lpszDefExt = NULL, LPCTSTR […]
