问题 Is it possible to run each child form of a MDI form on a separate thread? If so, can you please give some codes and example how to setup this? Thanks! 回答1: I can't tell from the question wether you are aware of the exotic nature of the solution you are proposing. I apologize if this answer completely misses the mark. I assume that you want responsiveness in your application. That you don't want other forms to "hang" while one form is doing work. However, having a different GUI thread per form

问题 How can I maximize a child window that fits only the client area but not an entire parent window? I don't want that the child window disappears under a main menu or other controls of the parent window. I have this code procedure WMSIZE(var Msg: TMessage); message WM_SIZE; procedure TForm2.WMSIZE(var Msg: TMessage); begin inherited; if Msg.WParam = SIZE_MAXIMIZED then begin ShowWindow(Handle, SW_RESTORE); Left := 0; Top := 0; Width := Form1.ClientWidth - 4; // The BORDER Height := Form1

问题 I'm working on a project that uses an MDI application with a navigation panel on the side. Currently it is a ListView. However, I would like to redesign it to be similar to the toolbox in visual studio 2008. If this is something that would require overriding the default paint method, it would also help if you could provide some good references on how to work with the paint method as I do not currently have any experience using it. Thanks in advance. 回答1: You want to be using a ToolBox control

问题 In my application when I make a form as a child form of my main MDI parent form, the child form stops showing Windows 7 default shadow effect behind forms. How do I get child forms shadow to show? Form obj = Application.OpenForms["My_form"]; if (obj != null) { obj.Focus(); } else { My_form c = new My_form(); c.MdiParent = this; c.Show(); } 回答1: This is normal, entirely by design. MDI child windows are not top-level windows, but rather a special type of child window that is designed to be

问题 I have 2 winforms Form 1 and Form 2. I have button1 in form1, when i click on button1 from form1 i display form2.

问题 When hosting WPF user controls within a WinForms MDI app there is a drawing issue when you have multiple forms that overlap each other that causes very distinct visual artifacts. These artifacts are mostly visible after dragging one child form over another one that also hosts WPF content or by allowing the edges of the child form to be clipped by the main MDI parent when dragging it around. After the drag and drop of the child form is completed the artifacts stay around generally but I've

问题 I need to insert some data from an edit control in a double linked list. How can i make this? The datatype of the edit control is CString and all are named like m_... for example m_anrede and so on...

问题 I have an MDI application where a dialog is called when the OnFileNew() function (processed by the theApp object) is called. This dialog allows the user to set values to some variables that then need to be passed on to the CChildFrame object that is created when the ->CreateNewChild() function is called. How do I pass these variables onto the CChildFrame object that is created by the ->CreateNewChild() function? EDIT: In response to an answer I got, here are the results for using ->Create()

问题 The click ,double click on mdi parent of the .net MDI form does not work is it a bug? 回答1: Well, that's not much to go on without knowing exactly what you click on. The gray background of the parent is a separate control, an MdiClient, not the form. You'd register a click event for it with code like this: public Form1() { InitializeComponent(); foreach (var ctl in this.Controls) { if (ctl is MdiClient) { (ctl as MdiClient).Click += Client_Click; break; } } } private void Client_Click(object
