| | Thanks to diafol for putting me wise to the imdb api. Unfortunately, due to my ignorance of all things related to web programming I am stuck. I fetch my information via the following Dim url As String = "http://mymovieapi.com/?title=@title&type=xml&plot=full&episode=0&limit=1&year=@year&yg=1&mt=M&lang=en-US&offset=&aka=simple&release=simple&business=0&tech=0" url = Replace(url, "@title", "Star+Trek") url = Replace(url, "@year", "1979") WebBrowser1.Navigate(url) … |
 | I don't know if it can be fixed but because Microsoft seems to be getting rid of Windows Live Mail (or Windows Live anything for that matter) in favour of Skype and Outlook.com, why not just switch to Outlook.com and go from there. You'll have to eventually anyway. |
 | Re: tic tac toe Your first mistake is not commenting anything. If we don't know what the code is supposed to do then we can't tell if it's not doing it. A simple comment such as "check for three X or O in a row" speaks volumes. Your second mistake is in hard coding … |

 | If you put all of the textboxes inside a container such as a panel or GroupBox you could simplify like Dim ptotal As Double = 0.0 For Each tbx As TextBox in GroupBox.Controls.OfType(Of TextBox)() ptotal += Double.Parse(tbx.Text) Next But you should ensure that the textboxes contain valid data first.  |
| | You could spawn it as a separate process with the same arguments you would use on the command line. You can also redirect stdout and stderr and capture it from within your app and display the text in a control. Do you need an example of how to do this? |
