According to the Message response method, the window is divided into two categories: Mode window and mode window. In the mode window
Before the operation is completed, you cannot enter another window to perform other operations. Used by the user to confirm important messages
You must provide feedback before continuing other operations, such as the error Prompt window. Non-mode windows are different.
You can open multiple instances at the same time and switch to any instance at any time. The most common example of a non-mode window is Excel.

To create a window, you must specify the display style of the window, such as the border, whether the control button is displayed, and whether the window can be floated.

Task. This type of window is not automatically closed when the application object is closed, unless it is closed by the user.
Therefore, if a main window is used in other places except the main operation window in an application
Close the applications before they are closed. Otherwise, even though the program ends, there are still several sporadic windows running.
Interesting situation of rows.
Subwindows are called by other windows and cannot be opened directly in applications. It can be overwritten by other windows, but not
It can overwrite other windows. It usually does not have a maximum or minimum control button, but developers can also set it
Have these. Sub-Windows do not have menus. You must pay attention to this when developing applications. Adjustable sub-Window
The size of the sub-window. The size and position of the Child Window are relative to its parent window.
. The parent window is the window that calls the Child Window. When the parent window is minimized, the Child Window also corresponds
Minimized, the floating range of the Child Window is limited to the parent window, that is, dragging the Child Window will not drag it
Out of the parent window.
The response window is a mode window, which must be responded to before continuing to execute the program; otherwise, the program cannot
Continue running. It is generally used to process important information, such as asking the user to confirm the selection and prompt the current error.
Information, enter required data in the next step, and so on. This type of window does not have a border or a maximum button, and cannot be changed
But you can drag it to change its position, which is relative to the entire screen. PB provides predefined
Response Window, such as MessageBox. This type of window is often used when important information is prompted.
Avoid using this type for business processing Windows. Because some controls may automatically use the information window
Displays some prompts. When such a control is in a response window

The maximum size and minimum size of the parent window. You can have menus and borders. It is often used to display auxiliary information of other windows.
In addition, the MDI framework and the MDI framework with micro help are often used in the development of application software.
In addition to the common window features, it also has its own characteristics.
