This is "using C # To develop smartphone software: Push box"
SeriesArticle21st. This article introduces the window/mainform. Design. Cs SOURCEProgramFile. This source file is mainform
This class inherits from the system. Windows. Forms. Form class, which indicates the main form of the push box. This article describes the practical work of the "design" of the push box, as shown in:
Let's take a look at the sections related to the design work in the mainform. Designer. Cs source code file (which is automatically generated by Visual Studio 2005 IDE:
Namespace Skyiv. Ben. pushbox. Window
{
Partial Class Mainform
{
// Note: A lot is omitted.CodeOnly the midesign-related parts are retained.
Private Void Initializecomponent ()
{
This . Midesign = New System. Windows. Forms. menuitem ();
This . Midata. menuitems. Add ( This . Midesign );
This . Midesign. Text = " Design " ;
This . Midesign. Click + = New System. eventhandler ( This . Midesign_click );
}
Private System. Windows. Forms. menuitem midesign;
}
}
The code snippet above shows the events that occurred when you click "menu-> data-> Design" on the main form of the push box game:
This. Midesign. Click+ = NewSystem. eventhandler (This. Midesign_click );
That is to say, the pop-up "design" dialog box (introduced in the previous article "use C # To develop smartphone software: Push box (20 ), users are allowed to select the level for the game "new", "edit", and "delete. After the user selects and clicks "OK", the actual action is completed in the main form, which is implemented by the mainform. Design. Cs source code below:

Notes:
- The midesign_click method is used to process the action to be taken when you click "menu-> data-> Design" in the main form of the program, she first constructs a designdlg class (this class represents the "design" dialog box). By initializing some attributes of this class, she obtains necessary parameters (from the Env class that represents the "Work Environment, refer to "use C # To develop mobile software: Push box (11)"), and then call the showdialog method of the designdlg class to display the "design" dialog box. Finally, if the user clicks the "OK" button in the "design" dialog box, the corresponding action is performed based on the user's selection (call the deletelastlevel or createoreditlevel method ).
- The deletelastlevel method is used to delete the last mark. This method actually calls the corresponding method of the Env class for work.
- The createoreditlevel method is used to create a or edit the current. This method is actually used to call the corresponding methods of the Env class for work. At this time, the entire program enters the "design" mode, waiting for the user's action.
- The design method handles the actions to be taken when you click the mouse in the "design" mode. This method actually calls the corresponding methods of the Env class for work.
