Sure. Here[^] is the language spec on the subject.
class Text
{
public Text(): this(0, 0, null) {}
public Text(int x, int y): this(x, y, null) {}
public Text(int x, int y, string s) {
}
}

I have made a custom control, which have a property named Items. Items is a collection. This collection can in the designer be changed by using the collection-editor accessed from the property viewer.
My problem is when I add items through the designer(collection-editor) in the property viewer. After adding a new item, it is shown in the control, but do I reload the form(by closing the window, and open it again), the item is not present - not visually in my control and not in the collection-editor.
I see that after adding items using the collection-editor, no code are added to the InitializeComponent function. I wonder if you need to do something specific to have it added correctly to the parents InitializeComponent function?
Thanks in advance,
Gooky

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
does the trick...

What do you add this to, the control's class or the property itself?
Thanks,
Alvaro
Hey! It compiles! Ship it.

the property
Actually, you also need to make a typeconverter. I found an excelent article about it:

check out a search on your pc for wininet.h
I'm not an expert yet, but I play one at work. Yeah and here too.

[System.Runtime.InteropServices.DllImport("wininet.dll")]

I created a dataviewmanager because i have dataset and want to provide different views on that that dataset. Is it possible to get the rows in a dataviewmanager? That is, I want to see the contents of the dataviewmanager. Does any one have any sample code?

Just reading up on "active directory - DirectoryEntry", come across this code fragment:
DirectoryEntry de = new DirectoryEntry();
String schemaNamingContext = de.Properties["schemaNamingContext"][0].ToString();
String defaultNamingContext = de.Properties["defaultNamingContext"][0].ToString();
What's:
a. schemaNamingContext
b. defaultNamingContext
Don't have anything from MSDN...

Funny, I'm using active directory to log people on my application and I was looking for something like that.

But, what is "naming context", it seems to me it means nothing more a LDAP path - therefore the phrase "context".

From what I see you get the schema for the container which maps out the organization like a xml schema.

i got it:
schemanamingcontext = schemanaming "container"
man, "context" is confusing, they really should named it "container" instead
norm
|
|
|
|
|
yeah ms and thier hype words
securitycontext = securitycontainer for the object (DCOM)
MTScontext == the container for the MTS object thats acts as a proxy much like Eneterprise Java Beans
need I go on...
now that I think about in my COM+ book for c++
COM+ wraps every thing with a container to proxy calls and what not and they call that...guess... ObjectContext
go figure

"context": something of interest resides in contexts (make sense doesnt it)
After you explaining it, I begin to look at the word "context" (and the world) differently: context==container. or more precisely, container==context (gee, that feels a lot better now)

funny though how I didnt undertsand that I did understand so-called "Context"

 Guys,
How can I call a c++ function from c#?
Many other sites say "call it as a DLL using InteropServices", but this seems like hard work. I have a single solution with two projects. One is in C++ the other is in c#. Why can't I just compile them together and have the linker resolve the references between them.
People are suggesting that you can't do this at compile time - only at run time via a DLL. But that seems crazy. Has anybody worked out how to do it>

Leppie,
So I think that you are saying that the only way to do this is at run-time - is that right? I am suprised that I can't declare a C++ function as public and have the linker resolve across the two languages.
I have given up trying to learn Microsoft C++, I think that the compiler are environment are awfull. When ever I try to use it I end up spending days trying to understand bizare error messages from the compiler or linker that give very few clues as to what might actually be wrong with the code. I am much happier with c#.
Regards
Rob
