SystemInformation::FixedFrameBorderSize Property
.NET Framework (current version)
Gets the thickness, in pixels, of the frame border of a window that has a caption and is not resizable.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The FixedFrameBorderSize property indicates the thickness of the frame, in pixels, around the perimeter of a window that has a caption but is not sizable.
The Width property of FixedFrameBorderSize is the height of the horizontal border and the Height property of FixedFrameBorderSize is the width of the vertical border.
The following code example lists all properties of the SystemInformation class in a ListBox and displays the current value of the property in a TextBox when a list item selected.
#using <System.Windows.Forms.dll> #using <System.Drawing.dll> #using <System.dll> using namespace System; using namespace System::Collections; using namespace System::ComponentModel; using namespace System::Drawing; using namespace System::Reflection; using namespace System::Windows::Forms; public ref class SystemInfoBrowserForm: public System::Windows::Forms::Form { private: System::Windows::Forms::ListBox^ listBox1; System::Windows::Forms::TextBox^ textBox1; public: SystemInfoBrowserForm() { this->SuspendLayout(); InitForm(); // Add each property of the SystemInformation class to the list box.
