The application will have a functional area that contains a category and two buttons. Click "my button" to test the application, as shown in Figure 2-8. Figure 2-8 Exercise 3: Add and use more controls to the existing functional area Exercise 1 shows how to use the MFC Wizard to create an application with a default functional area. Exercise 2

Select a query from the form before the method, although simple, but for the user is not easy to operate, the designer is also difficult to control, if the form to implement, these problems can be solved. As in the following form, the runtime user can select the driver's name in the combo box and press the query button to see the results of the query.

Problem reappearance: We have the following problem: selecting and clicking on a menu item on a combo control in Ext-js will pop up a dialog box, and if the dialog box is not selected, the focus is always on the original combo control and not positioned in the input text box in the pop-up dialog box.

The priority of the WM_PAINT message is very low. The window will not be refreshed immediately until other messages in the message queue are processed. When the window is re-painted, a button is re-generated, and its style is viewed when the button is generated. If the style is OwnerDraw, The DrawItem function is called. The OwnerDraw st

When you have more than one series in your Excel chart data, you typically need to make these series appear in the chart for comparison. Sometimes, however, you may not need to have each series appear in the diagram at the same time, you can add a drop-down list to select a series, and the series is displayed separately in the chart for viewing. If the following table is for a company's annual sales data, which is located in the A1:d13 area, you need to select a product family through the Drop-
