Every 20 mins it checks if there was a new post at a url which is pasted in a textbox. If the textbox is empty it checks for a file located in the same directory as it for the url, if not it uses Gaiidens journal as the default.
if (textBoxUrl.Text == "") { if (File.Exists(infFilePath)) { var urlFromFile = System.IO.File.ReadAllText(infFilePath); textBoxUrl.Text = urlFromFile; return (urlFromFile == "") ? "https://www.gamedev.net/community/forums/mod/journal/journal.asp?jn=251283" : urlFromFile; } else { textBoxUrl.Text = "https://www.gamedev.net/community/forums/mod/journal/journal.asp?jn=251283"; return textBoxUrl.Text ;} } else return textBoxUrl.Text;It then checks if there have been any new comments since the last check.
