. In every program I have written, I end up using some sort of INI file to keep settings from one run to the next. Instead of implementing it separately in each program, I finally got around to writing this class, CIniFile. It is simple to set up and use: After you create your CIniFile […]

Environment: VC6 The classes that come with Visual Studio for picking files and directories work, but they aren’t as clean and user friendly as they should be. My FilePickCtrl class is very similar to what Explorer uses for views, but with some slight differences. The following features are supported: Display small or large icons for […]

Environment: VC6 SP4 Introduction CZipFile is a lite library that allows you to get information about a zip archive. It is not able to decompress the files, but just retrieves the contents—the file name, file size, and so on. I developed it because I need a lite way to list the zip file’s contents on […]

I think that you do not learn very much from “sweet snippets” and many coders, including me, do sometimes only paste the code as […]

Environment: VC6, WIN XP SP1 While I was writing a LAN (Local Area Network) chat program, I noticed that many people on my LAN use different programs for message sending and that not all of them are compatible with other programs. The second problem I noticed was that many of them don’t work on Win95/98. […]

Environment: Visual Studio, All Windows platforms The Matrix, in its simplest form, simplifies working with arrays. This is the first of several articles that explains how to use the different features of the Matrix. In this article, I will explain the most basic features. The Matrix can be downloaded from CodeGuru, along with a brief […]

In this article, I will present some basically developed data-compression algorithms. Amid them are: RLE (Runtime-Length Encoding) methods Grayscale bitmaps compression class Including rle.cpp, there are two methods: CompressRLE and DecompressRLE. As parameters, these methods need input/output file names. The bit-length can’t get over 127 bytes. The input file can be presented in any binary […]

I love my work. I get to travel all over and help other people in lots of companies, design and build software, and in the course of my travels I meet great people like Joe Shook, Robert Golieb, Mark Davis, Lynn Kindler, Sommai Stone, Eric Cotter, Jack Poorte, Rob Howard, Susan Warren, Sondra Scott, and […]

Click here for a larger image. Environment: Visual C++ 7.0, Windows XP sp1, Windows 2000 sp3 Abstract This project demonstrates two non-MFC thread classes. One of them is a template library that can make any member function of any class execute in different threads, without the requirement of defining any static or global function. The […]

Mark Strawmyer Presents: .NET Nuts & Bolts Welcome to the next installment of the .NET Nuts & Bolts column. In this column, we’ll explore COM Interoperability, also known as COM Interop. COM Interop is the means to which we can use COM objects in a .NET application and build .NET objects that appear to be […]

If you want to work with nonresizable, nonmovable windows, insert this code into your project (SDI or MDI applications). int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (BaseClass::OnCreate(lpCreateStruct) == -1) return -1; // Do something // Remove positions of menu CMenu* pTopMenu = GetSystemMenu(FALSE); if(pTopMenu != NULL) { pTopMenu -> RemoveMenu(SC_SIZE, MF_BYCOMMAND); //Size pTopMenu -> RemoveMenu(SC_MOVE, MF_BYCOMMAND); //Move […]

Environment: VC6 SP5, VC.NET, Windows 2000 This code enables you to change the cursor dynamically on the scroll bar of the window, with scrolling capabilities. The variable m_nCursorID is used to prevent multiple loading of the cursor. CMyWnd is derived from CWnd. UINT m_nCursorID; //Current ID of the cursor resource CMyWnd::CMyWnd() { m_nCursorID = 0; […]
