Environment: VC6, Windows 98 This is an example of browsing the drives and folders on the system. This uses the Treeview/Listview control to achive the objective. This project is similar to the Windows Explorer available on the Windows Operating System. The project is available for download with source code; hence, fragments of code have not […]

Environment: ATL, COM, MFC Introduction A few weeks ago, I was desperately looking for a sample in which a C++ object can be sent across a COM interface but could not get any sample for the same. That’s why I decided to post this article here. Passing a C++ object across an ATL DLL is […]

Environment: VC6, Windows 98 This is an example of browsing the drives or folders on the system. This uses the Listview control to achieve the objective; the interface is similar to those found on FTP software packages, allowing the user to move backward and forward. The project is available for download with source code; therefore, […]

Environment: VC6 , Windows 98 This is an example of creating a Toolbar and Statusbar on a Dialog Window. I came across some project (I cannot remember by whom) and thought of developing a more Windows-like project. Code for Creation of Toolbar m_pImageList = new CImageList; SetupImages(m_pImageList); TBBUTTON tb; m_ToolBar = new CToolBarCtrl; m_ToolBar->Create(WS_CHILD|WS_VISIBLE|WS_BORDER|TBSTYLE_FLAT, CRect(0,0,0,0), […]

Environment: Visual Studio, VC++ 6.0, MFC, W9x/Me, W2k, XP Overview CListBox: This is a wrapper class for the ListBox control, and it’s used in almost every application. There is a little “gotcha” to this class: The horizontal scroll bar doesn’t work. Okay, I created it with the WS_HSCROLL flag set, the scroll bar is visible, […]

Environment: Windows CE Introduction CE Draw is high-speed graphics library in Windows CE. It depends on GAPI. This code was writen in C++ and uses embedded Visual C++ to compile it. It was tested on an iPaq h3600 with Windows CE 3.0. CE Draw uses double buffer and direct-write video buffer technology to enhance Draw’s […]

My friend John “Ballpeen” Armitage asked me about enumerators. Having experience in a procedural language like Natural provided him with the underlying idea; he just needed a little push to bridge the gap. In Visual Basic .NET (really the .NET framework) an enumerator is a class that implements the iterator pattern (see Erich Gamma, et […]

This addin was contributed by Walter Eicher. Environment: Visual C++ 6 Developer Studio in Edit Mode I like it when the edit screen looks like that. On the left side, I always place the *.h file, and on the right side I place the *.cpp file. Without WinPos, it’s very clumsy because the VC IDE […]

This addin was contributed by Jiøí Kutálek. Environment: Visual C++ GINA’s WlxGetOption function is not well documented on MSDN. I need to write GINA using smartcards, so I wanted to get information about the smartcards inserted during logon. Simply said, I want to use WlxGetOption to get some information. But what parameters have the function? […]

Environment: Visual C++ Description RotBlt is a function that works like BitBlt. It’s different in that it has an additional param theta which is the angle in degrees by which the source DC is rotated when blitted onto the destination. I wrote this in about 10 minutes, out of which I spent about 6 creating […]

In the last six months, I’ve done two cross-Canada tours to tell developers about Visual Studio .NET and what makes it so amazing. I’ve delivered lines like these: “All those things VB programmers couldn’t do—a service, a snapin, a multithreaded app, a console app—VB.NET programmers can do.” “Visual C++ programmers no longer have a privileged […]
