Program recognises but does not read .txt file

[Lazarevski]

I need to build a program which will upload a .txt file to the server, will read it using StreamReader and the populate an existing SQL table with the concent.

The first Page (profiles) does exactly that and works perfectly.. It has a text delimiter and splits the text into different columns. The second page should just read the entire thing with no delimiters and print it all in a single column named 'Info'.

I feel that I got a minor error in the syntax, so please be kind and help me with it. I still got 24 hours to finish this.

Thanks in advance!

At which line no# you got the problem.

[Lazarevski]

it executes the whole program with no problems but does not read file_name. The table is not populated. I think we should look for the error in the TextInput event. ObjStreamReader is where it's not working I think.

[kvprajapati]

Please remove try..catch and see what happen.

filename = MapPath("~/" + file_name);

StreamReader objStreamReader = File.OpenText(filename);

[Lazarevski]

Hah it works perfectly now.. That was odd since we did not change anything to the code.. Anyhow, thank you so very much!

I hope I won't need your help anymore :) but if I do, I'll know where to turn to! Bye and thanks again!

Thanks Lazarevski. Don't forget to mark this thread as "Solved" whenever you get proper solution.
