How would you know which one is the right choice for you? We mean, there are just so many options to choose from. The reason for this is that new/delete can be used for all types of dynamic memory allocations including class objects, whereas malloc/free cannot.Whether you want to create a site from scratch, edit a CSS file or make some quick edits to your website template, a good, solid text editor is just what you need.īut, it’s kind of tough to choose the best text editor, isn’t it? In C++ it is preferable to use new/delete rather than malloc/free. Memory allocated by 'new' should be deallocated using delete (or delete in the case of arrays). Perhaps its an ego thing.Ģ)Memory allocated by 'malloc' should be deallocated by 'free', otherwise we have a memory leak. Actually I don't understand why fellow programmers treat each other like that. His comments are rather pointless and needlessly rude in my opinion, and are particularly out of place as the first comment to your first article. For many of us, using an edit or rich edit control to produce a notepad like application was one of the first windows applications we made, and its not a bad way to start.ġ) Ignore the comments from Slacker007. There will be plenty of other programmers out there looking to learn how to use C++ for windows programming. Its always nice to see articles written by beginners for beginners. Read File and Show the Contents in the CEdit ViewĬongratulations on your first article. We first add the file open and save functions to the program as follows. The reason is that the default file open/save behavior is left empty. We can input text on the workarea, but the input result cannot be saved, also the program cannot open an exist text file. As a complete executable program, it provides the basic GUI including window, manu, toolbar, workarea and statusbar, and the user friendly entry point to customize its program behavior. The initial project created via WTL project wizard provides a basic program framework. What we need to do is to enrich the function of CEdit to a simple text editor. ![]() As a simple text editor program, the CEdit class is a sufficient start point. The CRichEditCtrl class is a WTL wrapper of the Windows ActiveX control " richedt20.dll", while CEdit is a WTL implement based on Windows API. The class CEdit and CRichEditCtrl are both possible to be the base of a simple text editor. In the WTL install package, there are several install scripts for the corresponding versions of VC++.īy creating C++ project via WTL project wizard, we can choose the base class for the document view. Obtain and install an open source WTL implement.Make sure that the paths of WDK head file, library file, and executable file are included in the environment setting of your Visual C++. WDK includes a standalone ATL/MFC implement that is necessary to WTL. Obtain and install a Windows Driver Kits (WDK) that is compatible with your Visual C++ program.If you have to use VC6.0, you need to install an STL library, such as STLPort, in your system and set up your VC6.0 to use the STL library. The version of Visual C++ should be above 6.0 since Visual C++ provides built-in complete STL support after version 6.0. Obtain and install a Visual C++ program on your system.If not, the reader should do some extra work to prepare the development environment. If so, the source code can be directly used as a VC++ project. ![]() We suppose that the reader has a Visual C++ with ATL/WTL support ready. In this tutorial, we will show how to build a simple text editor based on WTL objects. The main functions of a text editor include "Open/Save file", "Edit/View content", etc. Text editor is a commonly used application that can process text file.
