myCheckBox->Location = Point(5,5);
myCheckBox->Image = Image::FromFile( String::Concat( Application::CommonAppDataPath, "\\Preview.jpg" ) );
// Set the AccessibleName property
// since there is no Text displayed.
myCheckBox->AccessibleName = "Preview";
myCheckBox->AccessibleDescription = "A toggle button used to show the document preview.";
this->Controls->Add( myCheckBox );
}
public MyForm()
{
// Create a 'MyCheckBox' control and
// display an image on it.
MyCustomControls.MyCheckBox myCheckBox =
new MyCustomControls.MyCheckBox();
myCheckBox.Location = new Point(5,5);
myCheckBox.Image = Image.FromFile(
Application.CommonAppDataPath + "\\Preview.jpg");
// Set the AccessibleName property

備註
AccessibleName 屬性是一個標籤,它會簡短描述和識別其容器內的物件,例如 Button中的文字、MenuItem的名稱,或 TextBox 控制項旁顯示的標籤。The AccessibleName property is a label that briefly describes and identifies the object within its container, such as the text in a Button, the name of a MenuItem, or a label displayed next to a TextBox control.
如需可存取物件屬性的詳細資訊,請參閱 描述性屬性的內容。For more information about properties of accessible objects, see the "Content of Descriptive Properties.
