The CommonDialog type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | CanRaiseEvents | Gets a value indicating whether the component can raise an event. (Inherited from Component.) |
![]() | Container | Gets the IContainer that contains the Component. (Inherited from Component.) |
![]() | DesignMode | Gets a value that indicates whether the Component is currently in design mode. (Inherited from Component.) |
![]() | Events | Gets the list of event handlers that are attached to this Component. (Inherited from Component.) |
![]() | Site | Gets or sets the ISite of the Component. (Inherited from Component.) |
![]() | Tag | Gets or sets an object that contains data about the control. |
| Name | Description | |
|---|---|---|
![]() | CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
![]() | Dispose() | Releases all resources used by the Component. (Inherited from Component.) |
![]() | Dispose(Boolean) | Releases the unmanaged resources used by the Component and optionally releases the managed resources. (Inherited from Component.) |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Releases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
![]() | GetService | Returns an object that represents a service provided by the Component or by its Container. (Inherited from Component.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | HookProc | Defines the common dialog box hook procedure that is overridden to add specific functionality to a common dialog box. |
![]() | InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
![]() | MemberwiseClone() | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
![]() | OnHelpRequest | Raises the HelpRequest event. |
![]() | OwnerWndProc | Defines the owner window procedure that is overridden to add specific functionality to a common dialog box. |
![]() | Reset | When overridden in a derived class, resets the properties of a common dialog box to their default values. |
![]() | RunDialog | When overridden in a derived class, specifies a common dialog box. |
![]() | ShowDialog() | Runs a common dialog box with a default owner. |
![]() | ShowDialog(IWin32Window) | Runs a common dialog box with the specified owner. |
![]() | ToString | Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component.) |
| Name | Description | |
|---|---|---|
![]() | Disposed | Occurs when the component is disposed by a call to the Dispose method. (Inherited from Component.) |
![]() | HelpRequest | Occurs when the user clicks the Help button on a common dialog box. |
Inherited classes are required to implement RunDialog by invoking ShowDialog to create a specific common dialog box. Inherited classes can optionally override HookProc to implement specific dialog box hook functionality.
The following code example uses the ColorDialog implementation of CommonDialog and illustrates creating and showing a dialog box. This example requires that the method is called from within an existing form, which has a TextBox and Button placed on it.
private: void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ ) { ColorDialog^ MyDialog = gcnew ColorDialog; // Keeps the user from selecting a custom color. MyDialog->AllowFullOpen = false; // Allows the user to get help. (The default is false.) MyDialog->ShowHelp = true; // Sets the initial color select to the current text color. MyDialog->Color = textBox1->ForeColor; // Update the text box color if the user clicks OK if ( MyDialog->ShowDialog() == ::System::Windows::Forms::DialogResult::OK ) { textBox1->ForeColor = MyDialog->Color; } }
