菜鸟求助，组件的问题

[bjddd192]

我写了一个组件，用下面语句描述，在工具箱里面能够看见我的组件，可是拖出来，它老是跑到设计面板下面去了（比如窗体），
我希望能够把它拖出来就显示到设计面板上，当然我试了把[Designer(typeof(CompDesigner1))]去掉就可以了，不过我在
CompDesigner1中给组件加了几个菜单，用来自动生成一些熟悉，所以我希望能够显示出控件，这些自定义的菜单也能保留，我知道这样肯定是可以的，VS自带了许多控件都有这个功能，比如combobox，鼠标瞄上面后，它的右上角会出现一个小箭头，点击就会出来一系列菜单，我就是想实现这个效果，请大师们指教，下面是我类的申明：

[ToolboxItem(true)]
[ToolboxBitmap(@"D:\BjdddCSharpDev\Components\Resources\1.bmp")]
[Designer(typeof(CompDesigner1))]
public partial class ComponentTest1 : PictureBox

其中CompDesigner1继承于： public class CompDesigner1 : ComponentDesigner

try

public class CompDesigner1 : ComponentDesigner
=》
public class CompDesigner1 : DocumentDesigner

非常感谢，但是我生成后拖出来抛错，不知道是什么原因
抛错如下：服务容器中已存在服务System.Windows.Forms.Design.IEventHandlerService.
参数名:serviceType
请帮我分析下，谢谢

我的代码是：
using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel.Design;
using System.Windows.Forms;
using System.ComponentModel;
using System.Windows.Forms.Design;

namespace Bjddd.Dev.Components
{
public class CompDesigner1 : DocumentDesigner
{
ComponentTest test;
IDesignerHost host;
IComponentChangeService service;
DesignerTransaction designTran;
string testName;

DesignerVerbCollection m_verbs;

public override DesignerVerbCollection Verbs
{
get
{
if (m_verbs == null)
{
m_verbs = new DesignerVerbCollection();
m_verbs.Add(new DesignerVerb("生成东东", new EventHandler(OnGen)));
m_verbs.Add(new DesignerVerb("生成DD", new EventHandler(OnDD)));
}
return m_verbs;
}
}

private void OnGen(object sender, EventArgs e)
{
if (Component is ComponentTest)
{
test = (ComponentTest)Component;
host = (IDesignerHost)GetService(typeof(IDesignerHost));
testName = TypeDescriptor.GetProperties(Component)["Name"].GetValue(Component).ToString();

if (host == null)
{
return;
}

if (test.ID != 1000000)
{
designTran = host.CreateTransaction();
service = (IComponentChangeService)GetService(typeof(IComponentChangeService));
test.ID = 1000000;
service.OnComponentChanged(test, null, null, null);
designTran.Commit();
MessageBox.Show("生成成功!");
}
}
}

private void OnDD(object sender, EventArgs e)
{
if (Component is ComponentTest)
{
test = (ComponentTest)Component;
host = (IDesignerHost)GetService(typeof(IDesignerHost));
testName = TypeDescriptor.GetProperties(Component)["Name"].GetValue(Component).ToString();

if (host == null)
{
return;
}

if (test.Fields != null)
{
designTran = host.CreateTransaction();
service = (IComponentChangeService)GetService(typeof(IComponentChangeService));
test.Fields.Add(1);
test.Fields.Add(2);
service.OnComponentChanged(test, null, null, null);
Button b = (Button)host.CreateComponent(typeof(Button));

designTran.Commit();
MessageBox.Show("生成成功!");
}
}
}

}
}

还有个问题很想问下，自定义的组件，里面的代码怎么能不能调试的？

可以，启动两个vs.net ，一个加载控件，一个附加到那个vs.net 的进程
