This code provides a simple way of adding full AutoScroll capability to pretty much any window, I have provided a demo program which also incorporates the all of the code you need. I believe it works the same way as Internet Explorer, that is all of the behaviour I have seen from IE. The cursor […]

. This article first appeared in Windows Developers Journal, Oct 95. Brad has since enhanced the code and also made it available at the website http://www.visualc.com Many Windows applications need the ability to arbitrarily scale, or zoom, the contents of a window. An example of this is print preview, where you can zoom in and […]

This article improves on the code submitted by Umut Alev, Auto-Panning Windows. Ever since I saw the use of this Intellimouse control in the Infoviewer of DevStudio and later in Microsofts Internet Explorer, I’ve wanted an improved version that didn’t strain the eyes and had much finer increments than 1-pixel, 2-pixels etc. Eudora Pro can […]

Many professional MDI applications support selecting more than one file in the File Open dialog. It is easy to add this support to MFC applications. Opening files (and other document mamangement activities) is implemented in MFC’s CDocMananger class (see source file docmgr.cpp). CWinApp contains a member variable m_pDocManager poining to the CDocManager object to use. […]

Download demo 62K This demo shows how to use a small class, CIni, to load and save documents using a ini-file like system. The standard serialization way is nice and easy to use .. your nightmare starts when you have to read files made with another application. Sometimes, when the data to be saved are […]

If you’ve ever tried to do with MRU lists what Developer Studio 5 does i.e. have more than one menu, or put it on a submenu, then you may have had some difficulty, either with poring through the bowels of MFC or with a bug in MFC’s CRecentFileList. First I’ll describe my understanding of how […]

The article Open most recent file by Adam Solesby discussed how to open the most recently used file using the MRU list. This article develops the idea to starting a MDI application with many recent files opened. With MDI application it is sometimes useful to start a session with more documents opened or perhaps only […]

This is very simple, but I had never seen it anywhere else until I had to do it myself. It should save everyone some digging through the documentation. To make your program re-open the most recently used file, simply add the following code to your App’s InitInstance() between the calls to ParseCommandLine() and ProcessShellCommand(). // […]

Download demo code 158K In the upcoming Visual C++ 6.0, we’ll have a view class wrapper for the Internet Explorer, providing us with an html view. While waiting for VC6.0, we can have the HtmlView downloading the huge Tecno Preview from Microsoft. For those of you who needs, of all the Tecno Preview, only the […]

. In an earlier article Claude Turner has pointed out that RFX_Date does not handle invalid dates properly. This code is basically a replacement for RFX_Date that can handle invalid dates but still has the limitation that it can handle the year upto 2038 only. In the topic: “Database Programming”-‘look subject of the message’ there […]

This currently only includes one function. Allough is not complete I hope it shows how to set some of the field parameters. Also look at MS Knowledge base article Q152688 SetAllowZeroLength( LPCTSTR lpszField, BOOL bSet ) lpszField is the field name to be modified, bSet = TRUE for allowing zero length, FALSE for no zero […]

. During my current project, I found that I needed more functionality with my sql calls than CRecordset or CDAORecordset had to offer. These classes wrap the low-level ODBC API calls and act simular to a CRecordset, but allow me to execute any SQL statement without having to bind variables,etc. The main class for doing […]
