Environment: ATL/COM/COM+ Introduction In this article, I will explain the step-by-step procedure to develop and use COM+ components in the .NET environment and about “Component Services Explorer.” Before going to the coding part, let’s analyze how COM+ components and applications are managed. By using the “Component Services Explorer,” we can manage COM+ components and applications […]

Environment: Microsoft Visual C++ 6.0/SP4 ODBC 3.0 or above Microsoft Windows 95…XP Direct usage of ODBC is very complex. Anybody who tries to work with ODBC can say it. Also, ODBC is a function-level interface. It is a good universal interface, but all structured C++ applications look very horrible when plain ODBC calls are used. […]

Environment: ASP Components Summary This application uses ATL, MFC, ASP, and Crypto API. It will demonstrate how to make an ATL project that provides two cryptographic functions, how to use this component in your ASP projects, and how to register the component in MTS. The article also contains a GUI client console for directly testing […]

Click here for a larger image. Environment: VC6 I just wanted to access the history of Internet Explorer. I found no code anywhere to get it directly, but somehow I managed to combine some of code and get this working application. The code isn’t very great, but it is somewhat useful, you can say. I […]

Many times it is necessary to know whether a view is currently split or not. This method will return TRUE if the view is split and FALSE if it is not. NOTE: It does NOT detect multiple views, so don’t use it to determine whether UpdateAllViews should be called! int CMySplitterView::IsSplit(void) { CSplitterWnd * parent; […]

History MRCEXT was originally written towards the end of 1994. At Micro Focus, I was involved in developing a new Development Environment for COBOL (do I hear laughter ?). We were using beta copies of Visual C++ 2.0, and liked the look and feel of the sizeable dock bars. There was plenty of debate on […]

CColorFormView is derived from CFormView with custom background color. How to use CColorFormView class in your project? 1)Derive your form view class from CColorFormView class. For example: class CMyFormView : public CColorFormView 2)Change form view background color: You can specify background color in your form view’s OnInitialUpdate(): void CMyFormViewView::OnInitialUpdate() { SetWindowText(_T(“This is my formview”)); CColorFormView::OnInitialUpdate(); […]

CAnimateDlg (located in AnimateDlg.h/cpp) is a simple class derived from CDialog in order to implement user designed animated control. The user of the class has to call SetAnimationProperties() method and to pass to it the ID of the static control that will use as an animation control, number of frames in the “movie”, array of […]

Introduction QuickWin is a window application that spawn a Win32 console application redirecting his stdin, stdout and stderr handles to a window. The console application is hiding and all I/O operations are made through QuickWin. This is a very useful program to spawn script programs or console applications in a window environment without opening a […]

Environment: Tested on VC6 SP4 and VC7 Introduction On a project, I had the task of exporting data from an application as XML text. I collected as much information about XML as I being could and trained myself on the topic. When I was familiar with XML, I thought of a way to export the […]

In order to get around the limitations of using DAO recordsets in multiple threads, I have designed a class that forces all of the DAO calls to go through the GUI thread. Using the GUI message queue, all calls that come in to CMultiDAORecordset are forced to check the current thread using AfxGetThread(). A pointer […]

This article was contributed by John Czopowik. Environment: There is some confusion in the MFC world regarding CTreeView and tooltips. It seems as though the conservative approach of handling TTN_NEEDTEXTW and TTN_NEEDTEXTA notification messages does not work for some, known-only-to-Microsoft, reason. The following code requires comctl32.dll version 4.71 or later. Windows with IE ver 4.0 […]
