Here I found on the Internet API function SetParent (), and the online error has been modified, and gave a simple example code. Readers can test themselves:Public Class Form1 ' octopus brother, qq:3107073263 Group: 309816713 ' If you have any questions or good suggestions please contact me, everyone

recently working on a gadget and discovering a problem that was not encountered in the past to do the project: The Subform is blocked by the control of the parent form! As shown in the following:The subform's topmost has been set to true, and the parent form's controls have been placed on the ground floor, but the result is still pessimistic! Helpless, Google a bit, tried a lot of methods, the results found a simple solution to the problem, the code is as follows:Using System.Runtime.InteropSer

Recently I am working on a winform application.ProgramWhen the MDI form is used, a lot of trouble is encountered. One of them is how to solve the problem of not letting the child form be instantiated multiple times. I have searched the internet for a long time and found many solutions. Here I will introduce some simple methods. In fact, this is the singleton mode in the classic 23 design patterns. The following uses C # To implement it: Suppose

If the main window is an MDI window, you only need to set the ismdicontainer attribute to true. Add the following to the pop-up form:CodeThe child window can be nested in the parent form. Private Void Showform1_cick ( Object Sender, eventargs E) { Form1 childform = New Form1 (); Childform. mdiparent = This ; Childform. Show (); } If the splitcontainer container control is added in the main window, the child form cannot be displayed in the pa

This article from: http://www.cnblogs.com/xiaofengfeng/archive/2011/09/16/2178496.html One component in the DevExpress. net package is xtraTabbedMdiManager. It can display the MDI window as a TabControl style, which is very practical. Unfortunately, disabling tabs (I .e. sub-MdiChild) cannot be achieved by double-clicking. This is a bit difficult for friends who are used to software such as aoyou. View the xtraTabbedMdiManager events, such

In SDI and MDI of MFC, you want to get CXXXView from your CXXXApp (of course it inherits from CWinApp) (of course it inherits from CView) the view pointer is not an easy task. The following describes how to get it. OK. Let's get started.If we want to get the view pointer, first we need to get the pointer to the document and how to get the pointer to the document class, first we need to get the pointer to the Document Template (that is, CDocTemplate ),

First: Form room = new room (); // room is the new form nameFor (INT x = 0; x {Form tempchild = (form) This. mdichil.pdf [x];Tempchild. Close ();}Room. mdiparent = this;Room. windowstate = formwindowstate. maximized;Room. Show (); Second: // Query whether the form already exists by the form name. If yes, it is displayed. Otherwise, a new form is created.If (this. checkchildfrmexist ("subjectsetting") = true){Return;}Subjectsetting newfrm = new subjectsetting (); // subjectsetting is the

When the program went to the CSDN forum at night, I saw a friend in C # who asked "Prevent MDI child forms from being instantiated multiple times", and I wrote this article immediately. In fact, this problem is the classic 23 design patterns in the single piece mode (Singleton), following the implementation of C #: First we have 2 Windows Forms, the main form is called Form1, and the subform is called ChildForm. By adding a menu to the main form t

Many friends hope that the MDI child form will not be opened repeatedly. If the child form has been created, activate it instead of creating another MDI child form, in fact, the MdiChildren attribute provided by C # can solve this problem. Let's assume a treeview control and click the corresponding node on the treeview to create an MDI subform named after this no

Q:mdi How does the parent form send data to a subform, generally? A: For the most common MDI window, WinForm provides form.mdichildren this property in the properties of the form class to return all child windows.So we just inherit the form class and use this class to create a new child window.public class Mychildform:form{}Then, the Mdichildren property is used to get the child window, call the public method defined in the child window class, or the

Questions:(1) How do I open the other form inside it?The name of the form object.

DLL encapsulation of MDI child forms is a common software development technology, which has the following advantages: Personnel can write a module, including (interface + logic), without interfering with each other. After the module is developedProgramUnified Call.Program upgrade: when the program is upgraded, you can update a DLL without compiling the main EXE file. Different modules can be provided to customers based on their different needs and

MDI Form container:In general, a form is a top-level container and is not allowed in any other container, but if you set the IsMdiContainer property of a form to true, the form becomes the form container where you can put other formsIn the internal form, no matter how it is adjusted, it is not possible to jump out of its parent form containerNote: If you want the internal form to be maximized and not display the Maximize minimized button, set its form

The MDI with flexlib often encountered version problems earlier than 4.5, especially when the index subclass was added and when skin calls were made, there are always some buckets, The root cause of this headache is that flexlib is developed using the ha
