No pointers to 0xBAADF00D
I used to have several open-source projects available on CodePlex. At the end of 2017, the site was put in read-only mode and it will probably be closed at some point. Therefore, I have decided to move the projects that could still be useful to GitHub.
I have tried to assemble together information about the Visual C++ releases, the compiler and the frameworks (MFC and ATL). You can find these on many places, but it is often incomplete or focused on something particular (Visual Studio, C++ compiler, framework, etc.). The table below is the result of this effort. It is incomplete…
In Visual Studio 2015 MFC comes with a new features (something that has rarely happen in recent years): support for dynamic dialog layout. That means library support for moving and resizing controls on a dialog. In this article I will show how this feature works. Suppose we have the following dialog: What we want is…
Visual Studio 2015 is out and comes with lots of new features and improvements (see details here) but it also surprised me with what I call a demoting of C++ again to a second-class citizen, after some years when it looked like it regained importance at Microsoft. I’m saying Microsoft has demoted C++ because they…
This project has been moved to GitHub. New location: https://github.com/mariusbancila/mfccollectionutilities C++11 has provided support for range-based for loops. They allow iterating over the elements of a range without using an index.

However, if you try the following MFC code you get some errors because the compiler is looking for a begin() and end() function…
CPtrArray is a nasty MFC container that should not be used. However, if you deal with legacy code you may not have a choice and have to work with it. Unfortunately, the Visual Studio debugger is not able to display its elements, since these are pointers to void and that can be anything. In this…
A WinForms DataGridView control has the ability to automatically generate its columns and populate from a specified data source (which can be a DataSet, a simple list or something else). All you have to do is something like this:

var list = new List<Record>() {new Record() {Id = 1, Name = "item 1", Date = DateTime.Now}}; this.dataGridView.AutoGenerateColumns = true; this.dataGridView.DataSource = list; |
When you do the same in MFC, it doesn’t work (supposing that you followed all…
I was writing recently about an MFC bug in CDatabase class in Visual Studio 2012. In the meanwhile I have stumbled upon an even greater bug (check this report on Connect for the details): when the OpenEx function fails (wrong credentials, service not reachable, machine is shot down etc.) it corrupts memory. What happen next…
After migrating an MFC application from Visual Studio 2008 to Visual Studio 2012 I run into an unexpected error: the application was having problem fetching data from the SQL Server database. After debugging it turned out that function CDatabase::GetConnect that I was using to retrieve the connection string after opening the database (for different purposes)…
It is possible to host WPF controls in a Win32 application, and the other way around, but because of the differences betweeb these technologies there are various issues that can appear. One of these is handling of keyboard input. Without diving too much into differences between WPF and Win32, I will show how to provide…
