Download text + Search
Jan 14 2009 8:34 PM
I'm pretty new to c#. Basically there is a database that updates everyday on a webpage and it is a text file. (Example URL "example.com/php.203/list.txt")
As you can see it ends in .txt so I want to basically save that page as a text file within the application. I don't want the user to see any "save dialog" interface. Then I want it to search through the text file for the textBox1.Text and if it is found, label1 is visible if it is not found label1 is visible and text changes. I have some sample code I tried compiling but can't seem to get it working.
NOTE: If it would be easier and more efficient to just go to the webpage instead of download the text file then that would be fine. All I need to do is see if the text is in the text database.
Here's my code:
private void button1_Click(object sender, EventArgs e)
{
{
string htmlText = string.Empty;
StreamReader readerText = default(StreamReader);
Stream WebStream = default(Stream);
HttpWebResponse WebResponse = default(HttpWebResponse);
HttpWebRequest request = WebRequest.Create("MY WAB PAGE.TXT");
string SearchString = textBox1.Text;
WebResponse = request.GetResponse();
Webstream = Webresponse.GetResponseStream();
readerText = new StreamReader(Webstream);
htmlText = readerText.ReadToEnd();
if (htmlText.Contains(SearchString))
{
label3.Visible = true;
}
else
{
label3.Text = "Not found";
label3.Visible = true;
}
readerText.Close();
WebStream.Close();
WebResponse.Close();
}
}
But that code has many errors.
