BirthdayPicker Sample: Demonstrates .NET Framework Resources with Windows Forms

The BirthdayPicker sample shows how the .NET Framework resource mechanism can be used in C++ applications. It also demonstrates some common Window Forms components.

To get samples and instructions for installing them:

  • On the Visual Studio Help menu, click Samples.

    For more information, see Visual Studio Samples.

  • The most recent version and complete list of samples is available online from the Visual Studio 2008 Samples page.

  • You can also locate samples on your computer's hard disk. By default, samples and a Readme file are copied into a folder under \Program Files\Visual Studio 9.0\Samples\. For Express editions of Visual Studio, all samples are located online.

Building and Running the Sample

To take advantage of .NET Framework resources, C++ applications can use the .NET Framework tool WinRes.exe. This tool is specialized in creating ".resx" files (the equivalent of ".rc" files in Win32 C++ applications). Birthdaypicker.resx contains the imageList1 resource along with the collection of bitmaps it handles. The resultant .resx file is then compiled by resgen.exe into the file birthdaypicker.resources, which is then linked into the resulting assembly of the application.

To build and run BirthdayPicker using Visual Studio

  1. In the Visual Studio IDE, load the solution file BirthdayPicker.sln.

  2. In Solution Explorer, right-click the BirthdayPicker solution.

  3. On the Debug menu, click Start.

    Observe the Custom build step, running resgen.exe on birthdaypicker.resx and generating the resource file for the application. In addition, note the linker option /assemblyresource, used to link the resulting birthdaypicker.resources to the application.

  4. On the Debug menu, click Start.

Once the sample is running, two DateTimePicker controls are displayed. Select your birthday using the first control and an arbitrary date (such as today) with the second control. Once the date range has been selected, the linked tree control is propagated with multiple nodes interpreting the timespan in different ways. For example, the number of years or days elapsed, the equivalent in dog years or in fruit fly generations, and how many full moons have passed in this time interval.
