Could someone tell me what these lines of code are doing?

[Drew]

I am not sure what these lines of code are doing in this program. It loads a Sequential
file and makes Buttons for each Question.
Here is the entire main form. What does the lines of code do under
the cmdDisplay button? Under the Form_Load procedure, What does each line
do starting from the Redim statement to the End Sub? The Sequential file
is at the Bottom.

Dim m_intIndex as Integer



private Sub cmdComputeGrade_Click()
Dim intFileNum as Integer, strFilter as string
intFileNum = FreeFile
'prompt = "Enter your Name."

intFileNum = FreeFile
strFilter = "Text Files (*.txt)|*.txt|" & "All files (*.*)|*.*"
cdlOpenfile.Filter = strFilter
cdlOpenfile.ShowOpen
g_strFileName = cdlOpenfile.FileName

Open g_strFileName for input as #intFileNum

End Sub

'This will display the command buttons

[Raistlin]

The code you are talking about basically takes the infomation from the Input file and puts it into a 2D array that is then used to populate the textboxes in the cmdDisplay button.

I hope this helps

Under the cmdDisplay Button this line
txtInputbox.Text = g_strQuestionsAndAnswers(7, intIndex)

What does the 7 and the intIndex do?
Really, What does the complete line do?
