Environment: Windows NT 4.0 with sp3, VC6.0 I’ve previously sent a article about Wes Clyburn’s SMTP class. But I forgot to place the files TextPlain.cpp and TextPlain.h. Also, some people asked for a demo, so here you are. The demo project is very easy to look. Go directly to the function – void CEMailDlg::OnButtonSend() – […]

First add menu item Edit, and then add Cut, Copy, Paste, and even Select All to this menu. Then add the handlers to your CHtmlView class. Easy… void CWebBrowserView::OnEditCut() { ExecWB(OLECMDID_CUT, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); } void CWebBrowserView::OnEditCopy() { ExecWB(OLECMDID_COPY, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); } void CWebBrowserView::OnEditPaste() { ExecWB(OLECMDID_PASTE, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); } void CWebBrowserView::OnEditSelectall() { ExecWB(OLECMDID_SELECTALL, […]

Although the Developer Studio has a nice user interface, it still can be improved in many different ways. Here is an example of such improvement. The main goal for this project was to get a new look and feel for the dialog and toolbar controls, similar to this which can be found in Corel 8.0. […]

Having seen the 2 previous offerings which front load the enumeration in such a way that on a large or awkward network they can take a long time to return, I took a look at the browse for folder code which was rather cumbersome but with some tinkering reduced it to the following: LPITEMIDLIST pidlRoot […]

In a multiple view application, sometimes I need to implement different control bars for different views. This article presents how to implement docking control bar in a child frame. Suppose we want to embed a tool bar and a status bar in a child frame. First, declare them in ChildFrm.h: protected: // control bar embedded […]

Environment: The demo was compiled with Visual C++ 5.0 Overview For a true SDI application, it is oft necessary to have more than one view. In most cases, it is also necessary to have splitter windows containing other views. This sample can be used to implement multi-views in SDI application with or without splitter. Menu […]

For true graphic applications, it is necessary to zoom into the view to see details of the drawing. Using CScrollView to minimize programming effort, the only way to do this is to set the scroll size bigger according to the zoom factor. As an example, if you have an A4 document size (210mm x 296mm), […]

Environment: –> Additions: Ability to Disable Drag&Drop (via the CCrystalTextView::GetDisableDragAndDrop( void ), and CCrystalTextView::SetDisableDragAndDrop( bool bDDAD ) methods). Ability to add description text to Undo/Redo actions (via the CCrystalTextBuffer::CanUndo( PTSTR cpDesc ), CrystalTextBuffer::CanRedo( PTSTR cpDesc ), and AddUndoRecord(BOOL bInsert, const CPoint &ptStartPos, const CPoint &ptEndPos, LPCTSTR pszText, LPCTSTR cpDesc = NULL ) methods). Some notes: […]

This builds upon the information given by Aravid Corera in his article "Using a Multidimensional SAFEARRAY to pass data across from COM objects." It replaces Richard Warg’s article "Using a BSTR to Transport C++ Objects Across the DCOM Interface." Although a creative idea, it is not a good idea to use BSTR for things other […]

    I spend a lot of my programming time writing small COM Objects with the Active Template Library, and then using them inside of Visual Basic.  One situation that I come across often is: 1) Having collections of objects, and 2) Enumerating these collections.  I initially dealt with the collection by using the VB built-in […]

First of all, let me explain that this article is not intended to give you information about writing a Windows NT Service. Normally a Windows NT Service is supposed to be a console win32 application. But this is not a restriction. In other words, you can write a Windows NT Service that uses Microsoft Foundation […]

Memory-mapped files are a great way to share data between processes (see Zoran’s article Client/Server Interprocess Communication Via Shared Memory).  They’re easy to create, and easy to work with ’cause you just end up with a regular-old pointer to your data.  But despite the not-too-bad syntax… CreateFileMapping(); // or OpenFileMapping() if you’re a "client" pData […]
