The basic idea of having conventions is to have uniformity among the code written by different developers in a Team. The ulitimate goal is to make code Readable.
Still, if you want to look for conventions...Google it.

Well...the ultimate goal is really to have the code look like it was written by one person in a single session. Unfortunately, that is a complete ideal and isn't 100% practical in the real world without resulting to dogmatic and dictatorial enforcement.

Take a look at the Framework Design Guidelines[^].
That being said, the goal of a coding style is to create code that is easily readable and maintainable by any developer by creating a consistent "look and feel" and structure.

I am having state management problem.Currently I am using
<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="20"/> in my web.config file and its working fine
As there are two other state management methods StateServer and SqlServer I am a bit confused which one to use.And if anyone can tell will there any problem if i use the current setting?What are the changes I have to make in my current settings to avoid any problem as once I opened my website and a link was shown to me "the object has been moved here".When I clicked that my home page loaded but i was unable to access my admin page by logging in and redirected back to the login page.In my code the username is stored in session variable and if it is not provided the user will be redirected to the login page and even after providing the username and password I was kept redirected to the login page.I thought it definitely is session's issue. When that home page loaded directly by typing the url after a while, there was no problem.Can anyone explain what is wrong?Thanks

Hi,
can any body explain to me what is the Serializable Classes? and Why or where do we need to use such type of Classes?
Kind Regards

A serializable class, simplistically, is one that can be saved in it's current state to a medium such as the hard drive or into memory. One reason to do this is to transmit the class via a remote interface, so the remote application get's a copy of the data at the point at which it was serialized. Another reason would be to save the data to disk.

As Pete explained, serialization transforms object(s) to/from raw data for the purpose of transmitting or persisting them.
Another good thing to know is that one can use Google to find things out[^]

Hello,
I want a custom class "MyException" inherited from Exception class which will be used exactly same as the Exception class i.e. "MyException" must handle all the exceptions thrown by the try block. like
public TestException
{
try
{
int i=0,j=0;
j=25/i;
}
catch(MyException ex)
{
MessageBox.Show(ex.Message);
}
}
The catch block must be respond the same way as if i use
catch(Exception ex) which can handle all the exception.
Thanks

public class MyException : Exception
{
}
...
try
{
throw new MyException();
}
catch (Exception e)
{
Console.WriteLine("Exception caught! {0}", e.ToString());
}

Nothing in your sample code throws a MyException object. Therefore you will never catch a MyException.
It would appear to me that you don't understand how exceptions work. What benefit to you anticipate your custom exception having over catching an Exception? If I knew that then maybe I could understand what you are actually trying to do, and then I could guide you better.

I think the contents of the try block was made up and had nothing to do with his problem.  It seems that he does have a try-block that calls into something which might throw MyException, and the problem he had was that when *another* exception occured it was not caught.
The correct pattern to use has already been provided; I'll just add that the rule is to catch the most specific exception first, then less specific ones.
try
{
...
}
catch (MyException mex)
{
... // runs if try-block throws MyException
}
catch (Exception ex)
{
}
Finally, I'll just mention that a finally block might come in handy in some of these cases, such as when "cleanup" of any kind is needed - eg. close a database connection.

That is probably what he was actually looking for, but he did say '"MyException" must handle all the exceptions thrown by the try block'

Hello guys.. this is the first time im trying to make a program which uses a SQL databse file .mdf instead of a sql server.. and its also the first time i use the wizard in order to make connections and evrything else... before this all i had done it manually..
the problem im having is that after i add a row to the dataset it adds wonderfully but it does not save into the actual database file.. next time i boot up my program the row i added is not there
here is my code
Public myDataset As New ammDataSet
Try
Dim ta As New ammDataSetTableAdapters.ClientesTableAdapter
ta.Fill(myDataset.Clientes)
Dim clientRow As DataRow
clientRow = myDataset.Clientes.NewRow
clientRow.Item("cel") = "787689303"
clientRow.Item("direccion") = "something street"
clientRow.Item("email") = "huulagirl@gmail.com"
clientRow.Item("Name") = "John Doe"
clientRow.Item("tel1") = "787689303"
clientRow.Item("tel2") = "787689303"
myDataset.Clientes.Rows.Add(clientRow)
'myDataset.AcceptChanges()
MsgBox(myDataset.Clientes.Count & " " & myDataset.Clientes.Item(1).Name.ToString)
Catch ex As Exception
MsgBox(ex.Message)
End Try
what am i doing wrong? please help ive tried the acceptchanges event.. and also tried some of the alrady made by wizzard tableadapter methods and .. still no go

Try calling the update method of the data table and pass in the dataset.
ta.update(myDataset)

I created a very large dataset using the designer and now I realize that I can't access it in other forms. I have heard the way to go is to make it static although I am open to other suggestions. My goal is to keep the designer functionality because quite frankly I like the data binding features which have saved me a lot of time in other apps, but the reality is that this app requires dealing with the dataset on multiple forms.

You can make the dataset static (and internal / public) when it will be visible to any class in the project. In this case the dataset is created when it is referenced the first time.
If you want to control dataset creation or you want to have multiple similar datasets etc, you can create it when needed (for example in main method) and simply pass the reference of the dataset to the forms that need it.

Well actually that's what I didn't want to do. I want a master dataset that I can use from anywhere in my project. I have a form that all forms inherit that has an instance of this dataset set to prtected but I lose the data because it's not the same instance when it's inherited. I did find a workaround though. Instead of changing the data in the form and then trying to accessit in another form. I simply put the code that changes the database into a protected function, and then I run the function. In this instance at least, I achieve my results which is to keep the code that will be used on multiple forms on the parent form, and I can use the data on the child form. I am not sure if this qualifies as cheating or not but it does what i need it to do.
