mfc 多文档中怎样动态添加菜单项?

pDocTemplate = new CSingleDocTemplate(

IDR_MAINFRAME,

RUNTIME_CLASS(CMyScrollViewDoc),

RUNTIME_CLASS(CMainFrame), // 主 SDI 框架窗口

RUNTIME_CLASS(CMyScrollViewView))这个函数将文档类视类和框架类结合在一起，这个是单文档的组织形式，所以在单文档中框架类始终没有改变，所以可以动态加载菜单；

pDocTemplate = new CMultiDocTemplate(IDR_questionTYPE,

RUNTIME_CLASS(CquestionDoc),

RUNTIME_CLASS(CChildFrame), // 自定义 MDI 子框架

RUNTIME_CLASS(CquestionView))而这个是多文档的组织形式，可以看到第三个参数变成了CChildFrame，而不是CMainFrame，第一个参数也有所改变看，所以每新建一个多文档就会对应一个CChildFrame，所以动态添加的菜单不会显示在CMainFrame上，多文档不共用框架类

这个貌似不难，右键菜单用代码生成就行了。

你是要用ContextMenuStrip控件，生成的菜单可以用代码控制。如

// This code example demonstrates how to handle the Opening event.

// It also demonstrates dynamic item addition and dynamic

// SourceControl determination with reuse.

class Form3 : Form

{

// Declare the ContextMenuStrip control.

private ContextMenuStrip fruitContextMenuStrip

public Form3()

{

// Create a new ContextMenuStrip control.

fruitContextMenuStrip = new ContextMenuStrip()

// Attach an event handler for the

// ContextMenuStrip control's Opening event.

fruitContextMenuStrip.Opening += new System.ComponentModel.CancelEventHandler(cms_Opening)

// Create a new ToolStrip control.

ToolStrip ts = new ToolStrip()

// Create a ToolStripDropDownButton control and add it

// to the ToolStrip control's Items collections.

ToolStripDropDownButton fruitToolStripDropDownButton = new ToolStripDropDownButton("Fruit", null, null, "Fruit")

ts.Items.Add(fruitToolStripDropDownButton)

// Dock the ToolStrip control to the top of the form.

ts.Dock = DockStyle.Top

// Assign the ContextMenuStrip control as the

// ToolStripDropDownButton control's DropDown menu.

fruitToolStripDropDownButton.DropDown = fruitContextMenuStrip

// Create a new MenuStrip control and add a ToolStripMenuItem.

MenuStrip ms = new MenuStrip()

ToolStripMenuItem fruitToolStripMenuItem = new ToolStripMenuItem("Fruit", null, null, "Fruit")

ms.Items.Add(fruitToolStripMenuItem)

// Dock the MenuStrip control to the top of the form.

ms.Dock = DockStyle.Top

// Assign the MenuStrip control as the

// ToolStripMenuItem's DropDown menu.

fruitToolStripMenuItem.DropDown = fruitContextMenuStrip

// Assign the ContextMenuStrip to the form's

// ContextMenuStrip property.

this.ContextMenuStrip = fruitContextMenuStrip

// Add the ToolStrip control to the Controls collection.

this.Controls.Add(ts)

//Add a button to the form and assign its ContextMenuStrip.

Button b = new Button()

b.Location = new System.Drawing.Point(60, 60)

this.Controls.Add(b)

b.ContextMenuStrip = fruitContextMenuStrip

// Add the MenuStrip control last.

// This is important for correct placement in the z-order.

this.Controls.Add(ms)

}

// This event handler is invoked when the ContextMenuStrip

// control's Opening event is raised. It demonstrates

// dynamic item addition and dynamic SourceControl

// determination with reuse.

void cms_Opening(object sender, System.ComponentModel.CancelEventArgs e)

{

// Acquire references to the owning control and item.

Control c = fruitContextMenuStrip.SourceControl as Control

ToolStripDropDownItem tsi = fruitContextMenuStrip.OwnerItem as ToolStripDropDownItem

// Clear the ContextMenuStrip control's Items collection.

fruitContextMenuStrip.Items.Clear()

// Check the source control first.

if (c != null)

{

// Add custom item (Form)

fruitContextMenuStrip.Items.Add("Source: " + c.GetType().ToString())

}

else if (tsi != null)

{

// Add custom item (ToolStripDropDownButton or ToolStripMenuItem)

fruitContextMenuStrip.Items.Add("Source: " + tsi.GetType().ToString())

}

// Populate the ContextMenuStrip control with its default items.

fruitContextMenuStrip.Items.Add("-")

fruitContextMenuStrip.Items.Add("Apples")

fruitContextMenuStrip.Items.Add("Oranges")

fruitContextMenuStrip.Items.Add("Pears")

// Set Cancel to false.

// It is optimized to true based on empty entry.

e.Cancel = false

}

}
