well, [This] [Set of] [Articles] seem like a pretty good resource.
I actually don't have much personal experience with managed C++, but from what I've heard you basically just take C++ code and compile it with the .Net compiler. To me it mainly seems to be for performance critial stuff.
Personally I don't see much need for it since you could just import c++ dll's into .Net apps anyway.
However, using managed c++ does mean that your entire app would be in CIL (Common Intermediate Language, it's what .Net apps get compiled into), and thus it would be runnable in any .Net runtime (ie [Mono] on a macintosh).

This is a useful summary for C++ developers.
http://msdn.microsoft.com/msdnmag/issues/01/07/ctocsharp/[^]
Also Jesse Liberty's Programming C# book (now in 4th edition for C# 2.0) is excellent for quickly getting up to speed with the language and touching a bit on all the technologies. (He has a separate book specialising on ASP.NET.)

You'll like .NET 2.0 generics and the STL-like PowerCollections library then.

Good question! I've not used it but from what little I've read about it I think MS are positioning it as the "systems" language for .NET, analogously to the way that C/C++ is the systems language for Win 32. There are certain things you can do in MC++ (now C++/CLI) that you can't do in any other .NET language - rather like there are things you can do in C++ that you can't do in anything else. Whenever you have such scenarios I guess that's when you'll turn to C++/CLI

they are both as good.
Or any other .NET language is as good for that matter.
Choose the one you fancy the most...
Q:What does the derived class in C# tell to it's parent?

That's most definitely not true.
C# and VB.NET are almost interchangable. All you need to do is run whatever code sample you find through a VB.NET to C# translator to get a pretty good conversion of the code. You can use those few examples as a Rosetta Stone to figure out the language. You'll smack yourself when you see how easy it really is to convert between the two.
You can find a few online conversion utilities here[^].

labelPlaceHolder.Parent.Controls.Remove(labelPlaceHolder)
m_picker.Format = DateTimePickerFormat.Short
'Add any initialization after the InitializeComponent() call

I want in my RichTextBox this action to do: Backspace key takes the same action like left arrow key. Speaking generally I don`t want to delete characters by backspace key inside the textBox field unless it is the last character.
This code works in TextBox (do the action which I want) but unfortunatelly doesn`t work in RichTextBox.
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)<br />
{<br />
<br />
char c = e.KeyChar;<br />
int start = textBox1.SelectionStart;<br />
int lenght = textBox1.Text.Length;<br />
<br />
if(c == (short)Keys.Back && start!=lenght)<br />
{ <br />
e.Handled = true;<br />
SendKeys.Send("{LEFT}");<br />
return;<br />
}<br />
}
Can anyone help me? Sorry for my english

This is a re-post of an article I put in the COM section. It refers to .NET, COM and RPC so it's kind of hard to get coverage by people with appropriate skillsets.
Here is the problem:
As soon as I installed XPSP2 the startup code in a COM object instantiated by a .NET Service hangs. This in turn cause the service to hang.
Observations:
The COM object is instantiating an RPC Listener when it hangs. It specifically hangs on an endpoint registration, though raaaarely it continues through after getting an error code. The function in question is RpcServerUseProtseqEp and it returns 1740 (duplicate endpoint) or hangs. I am very sure the endpoint is NOT already registered.
If I manually start my service it will work.
If I delay the service start by 5 minutes (in code) it will start.
If I add almost every service dependency I can it will still hang.
If I have another service start the COM object (query a web page in background) it starts fine!!
This all seems to work fine under 2000 SP4 and under the previous XP. I may just require a service environment (if it works under 2003), but I would really like to fix this behavior. This requires .NET, COM & RPC familiarity so I may have to move this to another forum.
Assert(this);
-- modified at 11:21 Monday 3rd April, 2006
Ok, found the fix for this. The RPC listener code was initiated in the DllMain section of the COM object. The DllMain section is a bad section to put any init code in due to lots of system locks etc... being set when that is called. Evidently XPSP2 has added some that were not there before and a previously working app. can now lock up.

VB.net
I am trying to learn how to write a document and saw this code
below: How do they figure out the number of characters?
Number of characters with spaces?
WriteLine("<o:characters>326")
WriteLine("<o:characterswithspaces>382")
|
|
|
|
|
What do you mean?
What kind of document are you writing? Who are "they"? What characters are you talking about?
---
b { font-weight: normal; }
|
|
|
|
|
It is a word document that is being populated. I was just wondering how they figure out how many charactres are in the document. It is a template document
|
|
|
|
|
They count the characters.
As that answer was so terribly obvious, it's probably not what you were looking for. Can you be more specific in your question?

Hello,
I'm trying to parse a string according to a Type that's being passed in:
<br />
Type inputType = Type.GetType("System.Int32");<br />
string inputString = "314"<br />
<br />
TypeDelegator td = new TypeDelegator(inputType);<br />
<br />
return td.InvokeMember("Parse", BindingFlags.Static | BindingFlags.InvokeMethod | BindingFlags.Default, null, null, new object[]{inputString});<br />
However, the code above results in a MissingMethodException: Method "System.Int32.Parse" not found.
Calling System.Int32.Parse(inputString) works fine, so I have no idea what's wrong.
I've played a bit with the BindingFlags, but to no avail.
First person to answer correctly gets a cookie!
Thanks!

Parse is a Public Static method, so add BindingFlags.Public

Hehe, can't believe it was that simple.
Thank you very much!

Introduction
I've got a combobox on my form which is bound to a complex data source (IList).
myCombobox.DataSource = myList;
myCombobox.DisplayMember = "LastName";
myCombobox.ValueMember = "person_id";
The combobox itself is bound to a business object
myCombobox.DataBindings.Add("SelectedValue", myBusinessObjectInstance, "person_id");
So far so good. My combobox is filled with the provided Items and when I select an item inside the combobox the value get's updated in my myBusinessObjectInstance as expected.
Problem
As far as I understand the BindingContext class it holds all bindings (controls) bound to the same data source instance, in my case myBusinessObjectInstance.
But when I ask the form for the BindingContext attached to myBusinessObjectInstance the combobox binding is missing.
What do I miss?
myMsg.BehindDaKeys = "Jerry Maguire";
