hi all,

i want to write the content of a text file to another txt file exactly like what i have in original file.

i used write,writeline and put functions. but to my surprise, i found the text file is benig written without the new line character.

for example:

original file content:

aefaiojefioae
fafajfpfjafaffjaeiofjafjfjfi
faijfoijf
faioj

Para 2:
fafaopfopfkaokfopfaopkfopkopafopkfpoaf. fijaoijij
fafijoifjfiajparwto

MY COPIED FILE content:
aefaiojefioae fafajfpfjafaffjaeiofjafjfjfi faijfoij ffaioj Para 2: afaopfopfkaokfopfaopkfopkopafopkfpoaf. ijaoijij fafijoifjfiajparwto

Can anyone help me on how to write the content of the file exactly as what i have in original?

Thanks,
mahi.

Why not just use system.io.file.copy?

File.Copy is the simple way. Copying bytes, not characters (hence using a byte array), is the alternative.

Is the text in memory, or is it still in the original file?

Then do what everyone else said, and just use File.Copy

I agree. I think File.Copy would be your best solutions if you want your text file to be exactly the same as the original.

i have 2 following solution

the first

sqlcommand1.commandText = "insert into customers values('firstName','lastName','phone')
SqlCommand1.ExecuteNonQuery()

the second

'fill into datagridview
 SqlCommand1.CommandText = "select * from customers "
            SqlDataAdapter1.SelectCommand = SqlCommand1
            SqlDataAdapter1.Fill(DataSet1, "customers")
            DataGridView1.DataSource = DataSet1
            DataGridView1.DataMember = "customers"

'add new row into datatable
row = DataSet1.Tables("customers").NewRow()
        row.Item(0) = "firstName"
        row.Item(1) = "lastName"
        row.Item(2) = "phone"
        DataSet1.Tables("customers").Rows.Add(row)

'update data
SqlCommandBuilder1 = New SqlCommandBuilder(SqlDataAdapter1)
                   SqlCommand1.CommandText = "select * from customers "
                    SqlDataAdapter1.InsertCommand = SqlCommandBuilder1.GetInsertCommand
                    SqlDataAdapter1.Update(DataSet1, "customers")

Can you tell me what 's difference between those ?
And which is solution with higher performance D'Oh! | :doh:

Thank you very much!!

I see a lot of this.

Clearly the first is better etc. Why bother filling a dataset in order to perform an insert? The second option will produce the same SQL at the end of the day, but at high cost in processing to generating something you can type yourself in seconds.

If you have knowledge, let others light their candles at it.

The first one is a little better than the second b/c your using a bit more processing power on your app server to create the dataset you have on the second. In the first, most of the processing will be performed on the database server which is optimized for doing such computations.

Ah, the selection isn't there yet when you click it, so one would have to check what column the mouse is on;

VB.NET

Private Sub MSFlexGrid1_Click()      
    MsgBox CStr(MSFlexGrid1.mousecol)
End Sub

That should fix it Smile | :)

Music Sharing On LAN

Euphoric_me21-Dec-09 5:11

21-Dec-09 5:11

Hello all...

i am trying to develop a project in VB.Net as front end and MySQL or SQL server as back end.
The application is called online music sharing application which is supposed to work on LAN
All i need is that on the request of client or the keyword he types( which can be the name of singer, album or song name) is then searched in the database located at the server and so the list of files matching with the keyword is listed at the client side application.
Later the client can download any of the files among the list and listen to it
..

Here i would also admit that i have worked on VB but never on VB.Net and have no idea of, how the downloading feature and searching will be implemented.
I need to submit this project in say a week or 10 days(fully extended period and i cant take more time...)

i request if there is any help i can get as soon as possible.......
Sigh | :sigh:

Thankyou...

Why would you take a project that you have no experience in, and then rely on us to (probably) complete the entire thing for you if you don't understand simple concepts like executing a search? on a DATABASE no less? I'd go back and seriously explain to the client your technical constraints and have him choose another candidate.

If this is for school, you're SOL. Maybe business school next time? I hear you can coast through that...

[Edit] What kind of help did you think you where going to get exactly?

Do you have the database structure?

If so, does the database already contain data?

Have you worked with DB queries in your VB development?
