I'll help you solve this problem because my fellow CPians who have not had the pain of learning VB.NET can't seem to figure this out. This should work.
UIHierarchy UIH = DTE.Windows.Item(EnvDTE.Constants.vsWindowKindMacroExplorer).Object;
UIHierarchyItem samples = UIH.GetItem("Macros\Samples");

Btw just in case you are converting a Macro don't bother only VB.Net is supported for scripting.

This code is found in InitializeComponent() on my form, busFormManager1 is my class.
this.busFormManager1.ActiveDockControl = null;<br />
this.busFormManager1.ActiveMdiChild = null;<br />
this.busFormManager1.BarManager = null;<br />
this.busFormManager1.DefaultRegion = Medea.GfxLib.Windows.Forms.BusFormManager.ClientRegion.ToolLeft;<br />
this.busFormManager1.DockManager = null;<br />
this.busFormManager1.EnableMaximizedMode = false;<br />
this.busFormManager1.Parent = null;
now in design mode the form will not appear, only a blank white page with exception message Object reference not set to an instance of an object.. At runtime everything works fine, just the desinger kicks my form out.
I guess that my FormManager will execute code at this time, that is not valid or some object required for him are null at this time.
Now i've tried to use the DesignMode Flag, to test in which state the class is. Now it seem's that this flag is always false until InitializeComponent() is executed.
how to code this propertys the right way, that you can still watch the form in Designer ?
if you got a property like this
public Form Parent<br />
{<br />
set<br />
{<br />
this.parent = value;<br />
if (parent != null)<br />
{<br />
parent.Load += new EventHandler(....../<br />
parent.IsMdiParent = true;<br />
}<br />
}<br />
get<br />
{<br />
return this.parent;<br />
}<br />
}
now this property let crash the desinger, cause there's to much code in it to execute at InitializeComponent().
Any hint ? how did microsoft code all the components in dotnet ? they work always, not like mine ;(

Does your class have a default contructor ie one that does not take any arguements? If not, that should solve it, else I cant help you

When u write:
class MyClass {<br />
}
it's really:
class MyClass : object {<br />
}
Thats understood.
now for example:
MyClass myclass = new MyClass();
now
(myclass.GetType() == typeof(MyClass)) = true
Similarly:
object myobject = new object;
now
(myobject.GetType() == typeof(object)) = true
Hope u understand...I wouldnt have sleepless nites though

That will throw an compiler error as it is a duplicate definition.
You can however do this:
class MyClass : SomeOtherNamespace.MyClass {<br />
}
as the context for each MyClass is different

OK I think I know what u are getting to, the answer lies in inheritance.
class Base : object //this is not necessary as u know
{
public string Name {get;set}
}
Now Base class will inherit (iow have) all of it's base class's (object or System.Object, same thing) public and protected members.
class MyClass : Base
{
public int Value {get;set;}
public void DoStuff();
}
Now MyClass will get all of Base's public and protected methods, but remember Base has inherited some members from object as well, so it gets those as well.
It can get very confusing, I know. Designing a good class hierarchy takes time, only certain aspects might be affected at each level, but in the end all the inherited properties will be "visible" from top (most specialized class) to bottom (object). Look at the Form class and see how many members are actually inherited.
So in the end there can be only one! The same object class is used everywhere in .NET.
Hope this helps

never mind, you didnt understand what i said, my qq has been aswered in a later post by someone else. [look below]
BTW what i said was, from wot u said, i thought it was declared by
class objectBase : object {}
class object : objectBase {}
but never mind.

its not of any type - its a class with no parent.

I made a invisible control,and add a ico to it (by [[ToolboxBitmapAttribute("iconfile.ico")])
then I set the ico file as embed resource。at MSDN it said you can use projectname.filename.ext to access the resource embeded in a dll.
but I use [ToolboxBitmapAttribute(typeof(projectname.iconfile.ico))]or
[ToolboxBitmapAttribute("projectname.iconfile.ico")] ,it also can not access the icofile.
What shall I do????

I don't believe you can use icon files for the ToolboxBitmap 
Add the bitmap to the project, open up the properties panel (if it isn't already open) and change the Build Type for the icon to "Embedded Resource". The bitmap filename also needs to be named the same as the control, without the default namespace prepended.
Now change the ToolboxBitmap attribute to read.
[ToolboxBitmap(typeof(MyControl))] where MyControl is the name of the control.

Thank you very much!It works well now.
And useing ToolBoxBitmapAttribute really can load a ico file,but it is useless by use typeof(MyControl);bitmap is exact.
Thanks again.;)
This is a good place to discuss programing technique.

Any good ideas of what to buy in regard to writing custom control?
I'm looking for a book that explains the ins and outs of Control class,
like when to override createParams, WndProc.
I also saw a few books:
.NET Windows Forms Custom Controls
by Richard L. Weeks, Richard L Weeks
GDI+ Programming: Creating Custom Controls Using C#
by Eric White, Chris Garrett (Contributor)
are they good??
|
|
|
|
|
|
I have one at hand.
I agree with you that this one is a comprehensive guide on GDI+ and how to use these controls. But not in depth when it comes to writing our own controls.
|
|
|
|
|
I cant remember the books name now, but its on the WROX website (www.wrox.com)
Best is the source code for the book is available on the site (no need to even register) and the examples therein is so well written that you dont even need the book.
Hope you find it usefull

I have both the Petzold book (Programming Microsoft Windows with C#) and the Eric White book (GDI+ Programming: Creating Custom Controls Using C#).
The Petzold book is not aimed at custom controls, and although it is a good read it is probably not what you want. The reason I own both books is because the Petzold book has more GDI+ details, especially in regard to drawing paths, working with Beziers and other splines etc..
The Eric White book has three chapters directly relevant to designing custom controls. These are entitled:
An Overview of GDI+ and Custom Controls
Architecture and Design of Windows Forms Custom Controls
Design Time Support
However much of the book is slanted towards the design of custom controls. I would not like to be without either book, but if you can only get one, go with the Eric White book because it seems to best match your needs.
You should probably not override WndProc until you have explored other options. For example, you don't have to override WndProc to create a custom shape for your form or control. Instead you need only set the Region property of the form or control. Of course there are times you may really need to override WndProc. Just don't rush to it!
I live in the hope that sticking to a higher layer abstraction, which is what GDI+ really is, might someday make my life easier when it comes to porting code. But the reality is somewhat different!
I cannot comment on the .NET Windows Forms Custom Controls. I have not seen it.

How can I make a control in C# like
http://www.codeproject.com/treectrl/newtreelistcode.asp .
Is it possible to link with database ? When I change data in database this control will show the right thing in the same time ?
Thx.
