使用例
PrimaryScreen プロパティと GetWorkingArea メソッドの使用方法を次のコード例に示します。このメソッドには、Button1 という名前のボタンが配置されているフォームが必要です。
' This method will adjust the size of the form to utilize
' the working area of the screen.
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
' Retrieve the working rectangle from the Screen class
' using the PrimaryScreen and the WorkingArea properties.
Dim workingRectangle As System.Drawing.Rectangle = _
Screen.PrimaryScreen.WorkingArea
' Set the size of the form slightly less than size of
' working rectangle.
Me.Size = New System.Drawing.Size(workingRectangle.Width - 10, _
workingRectangle.Height - 10)
' Set the ___location so the entire form is visible.
Me.Location = New System.Drawing.Point(5, 5)
End Sub
// This method will adjust the size of the form to utilize
// the working area of the screen.
private void Button1_Click(System.Object sender, System.EventArgs e)
{
// Retrieve the working rectangle from the Screen class
// using the PrimaryScreen and the WorkingArea properties.
System.Drawing.Rectangle workingRectangle =
Screen.PrimaryScreen.WorkingArea;
// Set the size of the form slightly less than size of
// working rectangle.
this.Size = new System.Drawing.Size(
workingRectangle.Width-10, workingRectangle.Height-10);
// Set the ___location so the entire form is visible.
this.Location = new System.Drawing.Point(5, 5);
}
// This method will adjust the size of the form to utilize
// the working area of the screen.
private:
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
// Retrieve the working rectangle from the Screen class
// using the PrimaryScreen and the WorkingArea properties.
System::Drawing::Rectangle workingRectangle = Screen::PrimaryScreen->WorkingArea;
// Set the size of the form slightly less than size of
// working rectangle.
this->Size = System::Drawing::Size( workingRectangle.Width - 10, workingRectangle.Height - 10 );
// Set the ___location so the entire form is visible.
this->Location = System::Drawing::Point( 5, 5 );
}
// This method will adjust the size of the form to utilize
// the working area of the screen.
private void button1_Click(Object sender, System.EventArgs e)
{
// Retrieve the working rectangle from the Screen class
// using the PrimaryScreen and the WorkingArea properties.
System.Drawing.Rectangle workingRectangle =
Screen.get_PrimaryScreen().get_WorkingArea();
// Set the size of the form slightly less than size of
// working rectangle.
this.set_Size(new System.Drawing.Size(workingRectangle.get_Width()
- 10, workingRectangle.get_Height() - 10));
// Set the ___location so the entire form is visible.
this.set_Location(new System.Drawing.Point(5, 5));
} //Button1_Click
