No No sorry boss , i did not mean that.
i was trying to get some information about the deploymnet steps in vb.net.
Ones i have created the deploymnet project for my application.
then i am getting the error that the deployment project does not contain the .net framework exe.
But i have added to it.
May be i was wrong in pursuing the right steps to create a deployment project.
Now what i wanted to ask is that is there any link that illustrates the deployment steps...... including the way how to add the .net framework exe.

You can get the names of all the installed printers from the System.Drawing.Printing.PrinterSettings.InstalledPrinters collection. Then in your printing code, you can set the PrinterName property of your PrinterSettings object to the name of the printer you want to print on. To start the printing code, all you have to do is call the Print method on your PrintDocument object.

I don't have the time to put together a sample. I've already given you all the pieces you need, plus they double as search terms for use with MSDN or Google. You have to understand how the pieces work, then how they fit together. You'll be able to build this if you put the time into it.

Easy..

//lv_DtSet is dataset containing data.. 
if (lv_DtSet.Tables[0].Rows.Count > 0)
{
    foreach (DataRow lv_Row in lv_DtSet.Tables[0].Rows)
   {     
       if (!Convert.IsDBNull(lv_Row["ColumnName"]))
          String ColumnData = (String)lv_Row["ColumnName"];
       
       //Alternately u can use Column index also.
    }
}

What is the difference in using the column index and the column name?
which one is advantageous?

Both have their own importance.

Lets consider an example

Suppose you are getting data from Database using a Stored procedure.
Stored procedure contains Select as..
Select ID, Name, Value from Table1

When you will use this DB procedure in the C#..
You have 2 options Either to get by Column name or by Index..

<br />
long id;<br />
String Name, Value;<br />
<br />
// using Index<br />
id = (long) lv_DtSet.Tables[0].Rows[0][0];<br />
Name = (String) lv_DtSet.Tables[0].Rows[0][1];<br />
Value = (String) lv_DtSet.Tables[0].Rows[0][2];<br />
<br />
//using Column Name<br />
id = (long) lv_DtSet.Tables[0].Rows[0]["ID"];<br />
Name = (String) lv_DtSet.Tables[0].Rows[0]["Name"];<br />
Value = (String) lv_DtSet.Tables[0].Rows[0]["Value"];<br />

Now, if you look at Index case you don't know which value u r retrieving.
So, if someday DB person changes sequence of columns say..
Select ID, Value, Name from Table1
you r in trouble. B'coz no exception will be raised.. bt Name and Value will get interchanged.

So I will prefer to use Column name in this case. B'coz Changing of column name in DB is less likely. And eventhough the Sequence of columns in Select query gets changed, u don't have to change your code.

But there are some times.. u don't know column names OR u want to read data serially Column1, column2 etc.. then use Column indexes.

Depends on situation.
But I will prefer to use Column name as far as possible.

And by the way its.. ROHAN Smile | :)

As long as i know there is no difference in speed while retrieving data.

Hi all,

I was wondering if anyone knew of a relatively easy way to draw a random line through a value of X on a graph.

I then need to pull two points from the line.

None of this needs to be graphical or even displayed i just need the points as text output to be use later.

Any ideas at all would be greatly appreciated.

Use random numbers

Dim rnd As Random
s = rnd.Next()

thats not exactly what I meant

I'm not looking for truly random numbers

I'm looking for 2+ random points on a line that intersects x at a given point

If you generate the equation of the line, you can sub x values back in and calcualte y values.

e.g.

y = x + 2<br />
Say x = 2<br />
y = (2) + 2<br />
y = 4<br />
Therefore the point = (2,2)

Looks easy on paper, yet i imagine it's somewhat more difficult to accomplish in code. Hope this gets you started.

If u r asking for same icon for all the forms in ur application.

Is this what u r asking for???????
