I needed this class for keeping some other parts of a larger application portable. These other classes just require ostream & parameters for doing message and error text output (adapted lex and yacc generated classes actually). The basic ideas for the implementation came from a sample implementation for a X-Motif widget ostream by Dietmar Kuehl, […]

Introduction I was quite frustrated in with my application. I have a dialog with a simple multi-line edit (MLE) control. When I attempted to press the TAB key, the entire contents of my edit control would be highlighted! Evidently, this is the default action of an edit control when the Tab key is pressed. Anyway, […]

Oh no, yet another resizable dialog class! This is what you might think, but I have looked at several solutions for resizable dialogs, but neither of them met my requirements; so like all the others, I decided to make my own class. Some of the advantages in this solution: General solution, can be used in […]

This is a simple code snippet that enables you to dyamically enable docking and then dock any toolbar at runtime. To use (or test) this code, simply add the following code to a COMMAND message handler such as OnChangeToolBar and the code will allow you to re-dock any undocked toolbars. Obviously, one way of implementing […]

CAbsWordMngt::CAbsWordMngt() { CString strVersion; CLSID clsid; CoInitialize(NULL); m_Version = 9; if ( AfxGetClassIDFromString(“Word.Application.9”, &clsid) ) { m_Version = 8; if ( AfxGetClassIDFromString(“Word.Application.8”, &clsid) ) { m_Version = 0; AfxMessageBox(“WinWord version 8 or 9 not installed …”); return; } } }

Therefore, I wrote my own function (ShrinkBitmap) to give me the ability to shink and expand images in my own application, yet do so with the same quality I would expect from a graphics package. Take a look at the following table of images and you’ll see first a large image (the original) and then […]

class CElement { unsigned int m_magic_number; … CElement::CElement(const int index) : m_magic_number(0xfeedface), m_index(index) { } There are probably some other ways of doing it. For example, delete operator uses _BLOCK_TYPE_IS_VALID macro in debug mode. Either way, it is much safer to use for a little speed decrease. Note: In case your class is derived from […]

With a couple of lines of code, you can give your end-users the ability to resize any control. Suppose you wanted to give the user the ability to modify the size and position on a certain control? This example shows how to implement resizing controls on a dialog box as it is done when drawing […]

G’day everyone. I’ve written this DevStudio Add-In for two reasons – the main one is that I started learning C# by doing a conversion of something I’d written in C++ in Visual Studio, so I wanted to easily convert all the dialog boxes to C# forms. The second reason was that I had assumed that […]

. This article allows ones to: draw an image RGB color distribution using OpenGL in a dialog, use OpenGL display lists, draw antialiased smooth colored lines, implement mouse interaction (rotation), store and load an image from resource. We assume that our aim is to display the RGB color distribution of the following image (Figure 1) […]

I recently needed to be able to create new document/view that were contained within a DLL. After an initial search on CodeGuru, I didn’t find any artical which covered this subject. So I went ahead and tried to do it myself. It comes down to overriding two class’s which MFC uses to create and manage […]
