When coding against the Open File common dialog in the Win32 API, you can set a style to hide the places bar. But like other features of the Win32 common dialogs, this setting seems to have gotten lost in the migration to the .NET Framework. Creating a common dialog has never been easier than it is in the Framework, but this simplicity comes at the cost of some flexibility. In addition, in managed code there is no way to extend the layout of the dialog with additional controls.
There is no support in the .net framework for substantial changes to the existing dialogs. However solutions like this can help you.
