How I Can ?

Hello

I Understod that you wanna To Read and Write From File such as (Excel Sheet,Txt File)

okay:

Every File Have a Different Way To Connect To Your Application:

** Txt File:::

You Have To Creat a StreamReader To read from it or StreamWriter to Write into it like this:

dim file_to_read as StreamReader=new StreamReader("Here The Path Of Your File")

dim txt as String=file_to_read.ReadLine() <== read only line from file.

dim txt as String=file_to_read.readtoend() <== read all the file.

dim file_to_write as StreamWriter=new StreamWriter(" Here The Path Of Your File")

dim txt as string=" Somthing To Write"

file_to_write.writeline(txt)

** Excel Sheet or any office files

You Have To Connect Through The Connection Control

1) Creat OleConnection

2)Configure The PathString Of The Connection ..It Wil Be like

" Prvider 1.4 Ole........ect"

3) Creat DataSet and DataAdapter To Read/Write From File With SQL Statment

I Hope That Help
