Environment: VC5-6, Win9x, NT4-2000 Actually I wrote this code on VC6.0 and check them with BoundChecker 6.0. The CAlexfStaticHistogram control is a lightweight class suitable for displaying histograms. You can add new columns, additional text, change text orientation and direction of motion (if you change data at runtime). Using CAlexfStaticHistogram in a dialog is quite […]

First, I want to say, that I saw the article Multicolumn Combobox by Jakawan Ratiwanich, on www.codeguru.com. I inspected the piece of code, and I noticed that exist a array of items. That combo do not accept more than 200 items. In my mind, this is a inconvenient issue. So, I started to create a […]

Whenever a developer wants to create overlapping controls for example a Button with inner buttons, or a slider inside it, he faces a problem that whenever a user clicks on the button inner items disappear. I found a simple solution for this problem, which also prevents any distortions in the drawing if the inner controls. […]

Additions: When navigating code using the browse facility, the add-in would remove the highlighted piece of code, regardless of whether there was a bookmark set for that file or not. (Thanks to Matthew Ellis for the suggestion) Functionality of opening a file from the advanced page has been re-introduced once again. I did not seem […]

What does it do? As you may have noticed, this macro implements an action for Project Workspaces besides the default one (Open with MSDEV). The purpose of this macro is to allow you to do a background build of a selected configuration from the selected workspace. A Developer Studio instance is created invisible and starts […]

Environment: Visual C++ 5.0, NT4, Oxygen GMX2000 graphics accelerator Here is a fairly fast and easy way to use a Windows bitmap file (.bmp file) as a texture map in OpenGL. The limitation is that it only works with 24-bit bitmaps. To work with other bitmaps you need to pick apart the pixel values and […]

This demo app shows how to create an (MDI) app whereby opening or creating a new document automatically shows both views. The only drawback to this is that if you use the New Window item on the Window menu, it always creates just one view – the first type. I’m sure that can be resolved […]

Many times you may want to allow your users to see a preview of the file that they are about to open. CPreviewFileDialog does just that. The only work that you will have to do is to write a class derived from CAbstractPreview . Two functions will have to be implemented in this class. SetPreviewFile(const […]

I wanted to open a number of files at the same time from a Visual C++/MFC application. However, a ClassWizard generated application (with file support) only allows for the opening of a single file at a time. Therefore, I derived my own custom class from CFileDialog called MFileDlg. Using this class, I can now specify […]

Environment:Visual C++ 5 (and above) Setup procedure When designing a database application it’s required to sometimes make the user design a query. The programmer could write his own graphical query designer, but why not use Microsoft Query? This document describes the design and usage of the MSQuery class. This is a class which will communicate […]

I’m new to ADO and I searched for a piece of code to handle errors, I found the following code snippet in an article and wanted to share it with other ADO developers that might be looking for something similar. The following function (LogAdoErrorImport) can be called from any catch block in your program. // […]
