You can use ILMerge[^] to combine compiled .Net assemblies. Its a command line program so you can just load up cmd and run something similar to the following (as long as ILMerge.exe is somewhere in your PATH):
ilmerge /out:MyExe.exe MainAssembly.exe ReferencedDll1.dll ReferencedDll2.dll That will combine MainAssembly.exe, ReferencedDll1.dll and ReferencedDll2.dll into a stand alone exe called MyExe.exe. This exe can then be distributed on its own.
Hope this helps 
Cheers,
Will H

This error occurs sometimes when I use to save some record on a modal form...If I close the error message application would be closed.
Plz help me to trace out this problem...what could be the reason behind it.

You're trying to close a Modal form that isn't at the top of the z-order. In other words, You have a form that opened a modal form, that itself, opened a modal form. You have to close the forms in the reverse order that you opened them.

how can i set the session for my login page that no one is able to access the page directly.he/she must login first.

I think you are dealing with ASP or PHP related to a web site. If you do so, here is my advice:
You have to control every entry related to admnistration to your web site. It is likely create a sub procedure and check the session variable if it has a initiated value.
Sub Check_Security()
' check if someone is trying to get in the pages by directly typing the
' page name
If Session("Log_UserID") = "" OR Session("Log_MemberType") <> "admin" Then
response.redirect ("../quit.asp")
End if
End Sub
Check_Security() procedure should be in every asp or php (admin) related web pages (on top of the page). The example above shows how to control a user if he or she is a admin... You can change it vice versa...
I hopw that works out for you !

In my Global asax file aDo I need the code below newmail.fields.add and why do I need them?
The first one works but it puts my password in the code.
I am using IIS smtp mail and VS 2003

and a msn.com email account
The outlook email account works but the msn account does not?

click(). i'm storing the sql query in the str variable.

That's better, now the code looks like it's possible to run.
The code in the event seems to be correct. Do the records that are added in the database contain the same information, or is the second record mostly empty? The later would suggest that the event is executed twice.
Write something to the page from the event, so that you see if it is called twice.

What are the commonly asked questions in the interviews in vb.net for the fresher.

Not a comprehensive list, but a start.
You really should look at some employment agencies in your country too. Get to know the recruitment people and they can provide some assistance.
1. How many years experience do you have?
2. What is your highest academic qualification?
3. What is the difference between a Class and a Module?
4. Do you play football/soccer/cricket/paintball/drive go-karts/etc...?
5. Why should you not use global variables?
6. When, if ever, should you force the garbage collection to run?
7. In OO terminology, what does 'encapsulation' mean?
8. How would you test a new assembly?
9. If you have a programming question, where would you look for help and in which order...
a. Visual Studio Help
b. MSDN website
c. Google search
d. Your workmates
e. The Code Project
f. all of the above in that order
10. Do you comment all your code? (Honestly?)
11. Why should you be considered for this job? (i.e. what benefit can you bring to the company)
However, the most important one I ask potential candidates is:
12. Are you a TEAM PLAYER?

2. "Give a man a fish and you've fed him for a day. Teach him how to fish and you've fed him for life." I read that somewhere once

Oooohhhhh, I LOVE this one. In my experience, this means "Will you accept everything we say as gospel and not question anything we tell you or do to you?" Even way past the point where they cut your paycheck for doing outstanding work and give themselves raises afterward.

Hi Dave, yep I agree that's the way it could work - I have fallen foul of this too in the past, but I'm approaching it purely from a devloper's perspective (I'm not a manager) where pro-active teamwork is highly valued.
Among other things I've had guys metaphorically lock themselves in a closet and never interact with the rest of the team. When code review time comes along they take every fault found as a personal insult and invariably we find that their code has also diverged from the project scope considerably.
My philosophy is that it is not my code nor your code - all code is our code. (ego-less programming, the reference escapes me ATM) That way we all reap the rewards of our efforts.

You can use
Me.yourTableAdapter.Update(Me.yourDataBaseDataSet.yourTable)
Just as you load data
Me.yourTableAdapter.Fill(Me.yourDataBaseDataSet.yourTable)
and check whether you have created the primary key

Chatura Dilan

do you mean this?
Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Password="""";User ID=Admin;Data Source=""c:\databasename.mdb"";"
Dim objConn As New OleDb.OleDbConnection(connectionString)
objConn.Open()
Dim ds As New DataSet
Dim da2 As OleDb.OleDbDataAdapter
Dim sql As String
sql = "SELECT [Name] FROM Developer"
da2 = New OleDb.OleDbDataAdapter(sql, objConn)
da2.Fill(ds, "Developer")
Dim cb As New OleDb.OleDbCommandBuilder(da2)
ds.Tables("Developer").Rows(0).Item(0) = "yes"
da2.Update(ds, "Developer")
but it give me an "Invalid Operation Exception" ---"Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information."
can anyone tell me why?
p.s. do i have to created the primary key? why do i have to check?
