Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets the required creation parameters when the control handle is created.
protected:
virtual property System::Windows::Forms::CreateParams ^ CreateParams { System::Windows::Forms::CreateParams ^ get(); };
protected override System.Windows.Forms.CreateParams CreateParams { get; }
member this.CreateParams : System.Windows.Forms.CreateParams
Protected Overrides ReadOnly Property CreateParams As CreateParams
Property Value
A CreateParams that contains the required parameters.
Examples
The following code example extends the CreateParams property of a Button derived class. The CreateParams.Style property is changed, which causes the button to display an Icon rather than an Image. This example requires that you have a class that inherits from the Button class.
virtual System::Windows::Forms::CreateParams^ get() override
{
// Extend the CreateParams property of the Button class.
System::Windows::Forms::CreateParams^ cp = __super::CreateParams;
// Update the button Style.
cp->Style |= 0x00000040; // BS_ICON value
return cp;
}
protected override CreateParams CreateParams
{
get
{
// Extend the CreateParams property of the Button class.
CreateParams cp = base.CreateParams;
// Update the button Style.
cp.Style |= 0x00000040; // BS_ICON value
return cp;
}
}
Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
Get
Dim SecPerm As New SecurityPermission(SecurityPermissionFlag.UnmanagedCode)
SecPerm.Demand()
' Extend the CreateParams property of the Button class.
Dim cp As System.Windows.Forms.CreateParams = MyBase.CreateParams
' Update the button Style.
cp.Style = cp.Style Or &H40 ' BS_ICON value
Return cp
End Get
End Property
Remarks
The CreateParams property should not be overridden and used to adjust the properties of your derived control. Properties such as the CreateParams.Caption, CreateParams.Width, and CreateParams.Height should be set by the corresponding properties in your control such as Control.Text, Control.Width and Control.Height. The CreateParams should only be extended when you are wrapping a standard Windows control class or to set styles not provided by the Windows Forms namespace. For more information about creating control parameters, see the CreateWindow
and CreateWindowEx
functions and the CREATESTRUCT
structure documentation in the Windows Platform SDK reference at /.
Notes to Inheritors
When overriding the CreateParams property in a derived class, use the base class's CreateParams property to extend the base implementation. Otherwise, you must provide all the implementation.
