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

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

Spark version MDI titlewindow, with skin, maximum minimization, scaling, and function disabling In last year's project, multiple windows were needed. 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

It feels like 360 browsers to switch subforms by tab. Click the button on the menu item or toolbar to create a new tab, and generate a subform. Click the Cross on the tab to close the tab and release the subform object. To implement this style of

"When you open a child window body in MDI mode, you always cannot maximize the display, and the windowstate of the Subwindow body is set to maximized?" ", I believe a lot of people will encounter this kind of problem, please use the following method to set the MDI child form to maximize:1. Set the IsMdiContainer of the parent form to true;2, the WindowState of the form is set to normal;3. Open the subform i

Problem Solutions User32dll Systemruntimeinteropservices Code Summarize Problem A problem that has been discovered in the optimizer these days is that when a subform in an MDI form is activated, it is always obscured by controls in the main form (various controls).

I received a letter saying that the ActiveX control cannot be normally displayed on the MDI subform, but it is normal if it is displayed on a non-MDI form. I tested it, as he said. The scroll bar in the list box indicates that the content of the list is added, but it is not displayed. I searched on the news group and found that some people encountered similar problems, not just my ActiveX control. Finall

Mainwindow.h file: #ifndef mainwindow_h#definemainwindow_h#include Because this program is a multi-window (MDI) program, so there are different configurations for different text boxes in the program, such as document preservation, whether it is active, different file names and paths, so the specific operation of the document is implemented in the document class (subclass of Qtextedit), MainWindow is just a specific call to it. The following are the s

It is very easy to make the MDI form in VB. This is not easy in C #, but it is very convenient. First, add a form in C #, name it MdiMain, and set IsMdiContainer to true, so that the MDI main form is created. Then add a new form named MdiChild. Run the program now and you will find that only the main form of MdiMain is running. Because we didn't write any code, the second form certainly won't appear. Add t
