I get a number of press releases. Between releases from companies like Oracle, Corel, and Microsoft, I happened to get this release below. This one struck me as extremely odd and out of place. While it isn’t normal CodeGuru content, I thought you’d find it interesting. At first I thought it might be a joke… […]

Environment: VC6 What Are Web Services? During the last decade in the world, software didn’t get a huge influx as the Internet and the World Wide Web expanded. Most enterprises accomodated the new environments created by the Internet; browser-based applications became a standard.

An ATL-derived class to handle the structured storage of SAFEARRAYs (CComVariantEx). . Environment: VC6 (ATL), NT4/2000/XP Currently, the ATL CComVariant object can store itself to a “Structured Storage” file via the functions CComVariant::WriteToFile() and CComVariant::ReadFromFile(). However, this does not support CComVariant objects that contain SAFEARRAYs. Below is a derived CComVariantEx class in which these functions […]

Environment: VC6, NT4/2000/XP Current implementations of the Win32 wait functions—such as Sleep(), WaitForSingleObject(), and WaitForMultipleObjects()—will block the message pump when called on a window thread. A special case of this is a thread that calls CoInitialize(), resulting in potentially blocking COM method calls to an object. The attached code is a MS VC++ static library […]

Environment: eMbedded Visual C++ 3 I took the code of Zafir Anjum and tried to compile it with eMbedded Visual C++ to use it on a Windows CE-based device, but it didn’t work. So, I changed his code so that it compiles and runs correctly. The code of Zafir Anjum doesn’t work with Unicode strings […]

Classes and components provide a granular way to reuse code. A class of applications referred to as application servers represents a way for a client application to reuse a whole server application, which is often a significant improvement over reusing some classes or components. Microsoft has a whole suite of applications that are available for […]

Environment: VC6 SP4, NT4 SP5, WIN 2000/98/95 Here is an easy solution for hiding/replacing the right-click menu on a Web browser window. An example would be my situation. I had to implement a news group reader and writer. The news reader/writer used IwebBrowser2 control as the message display/edit window. If you do a right-click on […]

Environment: VC6 Well, all of you must know the MFC CList Class. I was having trouble using it so I made my own class and thought I would share it with you. The problem with the MFC class is that it does not provide direct access to individual elements of the list and sometimes you […]
