Hello again. I can't find my error in this code. Anyway, the assignment problem is to create a application that generates hundred numbers from 1 to 1000 and save the numbers to a file. The chapter only shows how to save to text file. I've decided to add a function to be able to load those saved numbers into the application. When I go to open the file, I get the error in the subject heading.
I also tried with no luck, per Visual Studio suggestion
intRandomNumbers array is declared as Class variable
Just in case, this is how I generated the numbers
I assume the data being pulled from the saved file, even though a text file, would be just string data, and thus need to converted to an integer. But I'm just not sure why it's all trying to convert to an integer when trying to add to a string array.
Thanks for any guidance/help in advance.
Code:
Dim inputFile As StreamReader
Dim strNumber(99) As String
Try
ofdOpenFile.Title = "Open File"
ofdOpenFile.Filter = "Text Files (*.txt)|*.txt"
If ofdOpenFile.ShowDialog() = Windows.Forms.DialogResult.OK Then
strFileName = ofdOpenFile.FileName
inputFile = File.OpenText(strFileName)
For intCounter = 0 To 99
strNumber(intCounter) = inputFile.ReadLine(strFileName)
[will add code to convert to integer]
lstOutput.Items.Add(intRandomNumbers(intCounter))
Next
inputFile.Close()
End If
Catch ex As Exception
MessageBox.Show("Error retrieving data" & ControlChars.CrLf & ex.Message, "Open File Error")
End TryCode:
intRandomNumbers(intCounter) = Val(inputFile.ReadLine(strFileName))Just in case, this is how I generated the numbers
Code:
For intCounter = 0 To 99
intRandomNumbers(intCounter) = (rand.Next(1000) + 1) 'generate a number
lstOutput.Items.Add(intRandomNumbers(intCounter)) 'add to ListBox items collection
NextThanks for any guidance/help in advance.
