If you want Label to grow as its text grows:
Label.AutoSize=true;
(this will make your label to grow in width)
if you want text to get wrapped and your label to become, multiline automatically:
Label.MaximumSize = new Size(max_width_of_label, 0); Label.AutoSize=true;
(in above label will grow but will not take care of other control, i mean it will not care about them, just try your self and see what happens)

I was looking for some good tutorial on net for com interop, i got following nice articles:

I had a datatable and i needed to show in a GridView in my ASP .Net page. Following is the code which help me to do so.
//get table to be shown in grid view; DataTable dataTable = GetRequiredTable(); //assing table to the DataSource property of GridView myGridView.DataSource=dataTable; //bind data from a data source to the GridView control myGridView.DataBind();
Here GetRequiredTable() is a user(example) function which return a table to display in to gridview.
You can also use DataSet in place of DataTable.
Error Message:
“The CLR has been unable to transition from COM context 0x1979d8 to COM context 0x197868 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.”
You get this nasty error message and your life is sucked. This happens when you are debugging your application and using breakpoints.
Fix For The Problem:
Go to menu Debug->Exception-> a form appears. Then in Managed Debug Assistants section, just uncheck the ContextSwitchDeadlock.
Note:
If you are not able to see Exception MenuItem in debug menu, then add it from Tools->Customize->Commands.
I was going through an ASP.Net book, and thought of writing extremely simply Hello World example. This will give an insight of how simple and small page you can write using ASP .Net.
For each example I have given asp .net code and corresponding browser generated code.
Example1
<%@ Page Language="c#" %>
<%Response.Write("Hello World");>
Brower Source:
Hello World
Example2:
<%@ Page Language="c#" %>
<script runat="server">
void SayHello()
{
Response.Write("Hello World !");
}
</script>
<html>
<body>
<% SayHello(); %>
</body>
</html>
Brower Source:
<html> <body> Hello World ! </body> </html>
Static classes in C# doesn’t have instance constructor(constructor used to initialized instance of a class) since it can’t be initialized. Static class is initialized only once when they are used first time in application.
So i was wondering how we can initialize a member if really we need. The answer is using static constructors.
Here is the example of how you can use static constructors in your static class:
Here, messagebox will be shown when first time StaticClass.Hi() method will be called.
Note: static constructors could be used in normal classes also.
Many times during development we really don’t want to handle exception every where, rather we like to throw it again. But what is the best way to do it:
OR
This article I found in net gives really good insight of it. It suggests to use first method, as it would not truncate previous stack trace information.
When we are struggling with String concatenation issues, specially which is the best way to concatenate the strings. One of my colleague suggested following articles to me.
though this may not be giving every thing you are looking for, but really very nice and worth readable for the .NET developers.
Follow this process:
String conString = “server=server_name; user id=user_name;
password=password; database=db_name; pooling=false;”;
String queryString = “select * from employee;”;
using (MySqlConnection mySqlConnection = new MySqlConnection(conString))
{
using (MySqlDataAdapter adapter = new MySqlDataAdapter(queryString, mySqlConnection))
{
DataTable dt = new DataTable();
adapter.Fill(dt);
dataGridView1.DataSource = dt;
}
}
