Hey scriptick, in your code after line number 12, line(string) contains the entire text of the text file. And in line number 16 you are checking whether the line(string) is started with the inputted text or not. You asked something and you done something else.
By the way thanks for asking. 'm good, hope you too good (:

Hey scriptick, you are doing it wrong. 1) You should read your text file line by line and store it in an array. 2) Or in your code after reading the file once, split the string(line) using 'Carriage Return' and store it in an array. Then use LINQ (which Frinavale mentions) to extract the words which start with your input character from that array.
NOTE: You haven't closed your StreamReader in your code.Last edited by Frinavale; Oct 28 '13, 09:12 PM.Leave a comment:

Hey EllahV, i don't know why you're getting an error message for 'label1' because you didn't shown the declaration part of it. But regarding 'buttn', the scope/life lies only inside the 'button1_Click' event method, you can't access it from the outside of it.Leave a comment:

Hey Prithivi989, i think we can't get the exact date.
Case 1: If the number is 12122012 means we can find out the date (12th December 2012).
Case 2: If the number is 122012 means we can find out the date (2nd January 2012).
Case 3: If the number is 1232012 means we can find out the date (3rd December 2012).

Hey thomaaxha, you can use SQL COUNT() Function. Like this,
Code:SELECT COUNT[Column_name(s)] FROM [Table_name] WHERE [Condition]
After this check count value, if it is > 0 then value already exists in table else not exists.Leave a comment:
