Thanks - the tooltip works great. Much appreciated.

TabControl tc = new TabControl();
tc.TabPages.Insert(0, new TabPage());
Console.WriteLine("1 == {0}", tc.TabPages.Count);
Console.ReadLine();
Output:
1 == 0
Does anybody know why TabPageCollection.Insert silently does nothing? Doing
tc.TabPages.Add(new TabPage());
works fine, so why won't Insert?

If I use reflector to decompile TabPageCollection, this is the definition of Insert:
void IList.Insert(int index, object value)<br />
{<br />
throw new NotSupportedException();<br />
}
Firstly it is hidden, so you cant have been using the exact code you posted, you must have been casting tc.TabPages to IList, second its unsupported.

Thanks for the reply. Also thanks for the reference to Reflector. What a great program!
If I load the .NET Compact Framework, then disassembling the method returns
public void Insert(int index, TabPage tabPage)
{
}
which makes sense given the output I'm getting. (Interestingly, I don't get NotSupportedException when disassembling the regular .NET 2.0 framework - it makes a reference to this.owner.Insert, followed by some try{}catch{} stuff. Maybe something got changed when I tried installing Avalon/WF/.NET 3.0 beta)
So I guess my question now is this. Why is Visual Studio using the compact framework, and how can I change it?

1-open the class code and know the updates (because their are many windows apps)
2-change the version of us

I am currently working on a smartphone project that needs to
communicate with some COM component. Since the .NET compact framework
does not support the DCOM, I decided to create a web service to expose
the COM component's methods and events.
As the some of the COM methods return int** or byte** data back to the
caller, I manually changed the generated interop assembly ( from
IntPtr to IntPtr& for the out going parameter int*** or byte**) after
generating the intermedate language file using ildasm.exe and
regenerate the interop assembly using ilasm.exe utility in order to
get the arrays of bytes or integers for the web service methods.
Here is the problem I am facing:
The web service methods caller can only get the first elements back
from the COM component while windows caller can get all the data back.
I wonder if I need set some binding attribute to make it work for web service.
I would be very grateful if you could help me out.
Thank you.

Hi All.
I learning in this week how to use regular Expression in c# ( .Net 2.0 - IDE 2005 ).
I don't understand if use regular Expression "cost" more then use some scan string to know validation of some sentence ( that build from string ).
  
1. Some one can solve my understanding problem ?
2. How can i know if using regular Expression is more effective ? where can i find some article about effective use ( or more effective use ) in C# trait ?
Thanks for any help ... ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

RegEx costs more, plainly. A ferrari also costs more than a push bike. RegEx can do things that are hideously complex to try and do with string mashing.
If you search the site for Expresso, that's a tool for playing with regex. Basically, if string mashing can solve the problem simply, use it. But, having said that, outside tight loops, it's not likely to matter which you use.

OK , i see that.
Bug but lets take some example of some dummy application that need to analyze some document with 100000 line in this document.
To know if some expression X is in line i can do it in 2 ways
1. Scan and look for Y string.
2. Use regular Expression to find matching.
But if i need to look for 100000 line and look for match with 10 strings - what you recommend to use ? regular Expression or string look for ?

Write both instances and time them to find out which one is faster. Then if you want to know which is faster for case(n) and case(

No.
To access the server services you must have client software.

Okay i want to do this: Use the child's MDIParent property to get the parent form. Cast it to the
MDI parent type. Then set/use the properties of the parent.
What is the correct syntax because i keep getting Errors?
|
|
|
|
|
MyParent form = (MyParent)this.MDIParent;
However, if you need to pass data from the child to the parent based on a user action, it is better to do it with events. This way you avoid casting and you do not risk changes to the parent form or its' children.
Search MSDN and you will get a good tutorial on establishing events. The altered data can be in your custom event arguments.
|
|
|
|
|
There are different approaches, but I think this will assist
Code for the Closing event of the Child form i.e. on closing the form; here is the code: In this code the frmMain is the MDIParent of the frmItem, but casting is important in retrieving the properties of the parent form:
private void frmItem_FormClosing(object sender, FormClosingEventArgs e)
{
Form f = sender as Form;
((frmMain)f).statusStrip = frmItem.statusStrip;
}
