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.
Read More My open-source projects are moved to GitHubI 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…
Read More Version history of VC++, MFC and ATLIn Visual Studio 2015 MFC comes with a new features (something that has rarely happen in recent years): support for dynamic dialog layout.

The problem with the tool is that it does not format GUIDs in plain text, which I happen to need many times (in source code, database tables, etc.) and I suppose is a feature needed by many…
Read More GUIDGEN with plain text GUIDs and case optionsVisual 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…

Read More Bindings for DataGridView hosted in an MFC applicationI 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…
Read More Second CDatabase bug in MFC in Visual Studio 2012After 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)…
