When I create a data center charging system, I will encounter the following problem: the label, text, commandbutton, and other controls cannot be added to the parent form. That is because only controls with align or invisible (such as timer) can be directly placed on the primary form of MDI. Because MDI is the container of other child forms. If a button can be placed, the button will be covered when the sub

Browser Integration Teaching-add macro support to browser programs This tutorial provides a method to add macro support to a browser program. You will see how to add macro support to the MFC program. This article also discusses how to expand the chtmlview function in vc6, how to implement the MDI structure browser, and how to analyze the DHTML document structure.

Background settings When we design software, the realization of the function is of course the first, but the Man-machine interface must not be neglected. Sometimes we want to add a more beautiful background to it, and it's on the screen all the time. We can keep a form from being released, but that's not good. The MDI form provided by VB (Multiple document interfac

For Integrated Wiring, telecommunications and equipment are the gathering places of data, voice, and image services. Its importance is self-evident. However, they have made great efforts in their overall design, device finalization, hardware configuration, construction and maintenance, and other aspects. However, the construction party often ignores the maintenance and installation of the largest number of equipment in the telecom and equipment rooms-cables and optical fiber jumpers, it will cau

I believe everyone has met this computer black screen and solved it. But have you seriously summarized the cause? So how should we solve it? You may not know this, but I believe you have never met a computer black screen user. What should you do if a computer black screen suddenly occurs? Not afraid. This time, the computer knowledge editor will analyze it for you. The specific tutorial is as follows, hoping to help you: 1. Handling of black screen faults if no power is available 1. Check whethe

describes how to create twisted pair wires in several application environments. MDI indicates that this port is a cascade port, while MDI-X indicates that this port is a common port. 1. ethernet network adapter and Hub Connection: When a PC or other network device is connected to the hub, the network cable is a direct connection, and the two ends of the twisted pair must be a pair of connections.

attribute when you click the close button. If the form is a multi-Document Interface (MDI) parent form, the formclosing event of all MDI child forms will be triggered before the formclosing event of the MDI parent form is triggered.

(CTestBView )); 11) multiple document templates can also be added to a single document. However, multiple document templates are generally developed using the MDI method, which is very similar to the preceding view obtaining method, please refer to the following four sources (11, 12, 13, and 14) for details:Http://sanjianxia.myrice.com/vc/vc45.htm)You can use CWinApp: GetFirstDocTemplatePostion to obtain the location of the first document template re

I haven't used MFC for a long time, so I forget the complicated process of creating windows, documents, and views of the MFC framework.Next we will track an mfc mdi application for further study or study.Use Appwizard to create an MDI application. The application I created is called mditest. In this way, MFC generates the following classes:Class Name FunctionCmditestapp is derived from the cwinapp applicati

After the motherboard is installed in the chassis, the following is the final power supply, the outer end of the chassis, hard drive cable, CPU heatsink line, motherboard power cord and other wiring issues:(1) Read the user manual of the motherboard to understand the location of each connection and the relevant instructions.(2) Generally according to the power cord interface and the shape of the socket can

Switch Port cascade knowledge to improve the route, when the two ports are common ports, namely MDI-X) port and MDI-II port, should use a straight-through cable. When four vswitches are uplinked, the network span can reach 500 meters. This distance is enough for a small network in the same building! Port cascade of twisted pair Switches Cascade uses both common ports and special

There are also many types of vswitch ports. Different ports have different functions. Here we will analyze the knowledge of vswitch port cascading and improve the route in all aspects of vswitch port cascading knowledge, A straight-through cable should be used when the two ports that are cascaded are normal ports (MDI-X) ports and MDI-II ports, respectively. When four vswitches are uplinked, the network spa

MDI features:1) All child windows are displayed in the workspace of the MDI window, which may move or change the size, but are restricted to the workspace.2) When the child window is minimized, it is displayed as an icon on the MDI form rather than on the taskbar. When the MDI form is minimized, the

encapsulated result is a set of development templates (or models) for programmers ). Programmers use different templates for different applications and purposes. For example, SDI application templates, MDI application templates, rule DLL application templates, extended DLL application templates, and OLE/ActiveX application templates. These templates all adopt the document-centric idea, and each template contains a group of specific classes. The comp
