String. Is this Possible? Still trying to figure this out after 4 hours. Thank You.

Hello,
I am changing the property of a control:
myMenu.Item(0).Item(1).Text = "Something"
What I want is to use the path which value is in a string. Something like:
Dim path As String = ".Item(0).Item(1)."
Now I would to the following:
myMenu & path & Text = "Something"
Of course this doesn't work.
Any ideas?
Thank You,
Miguel

There is no simple solution that will enable that idea to work. Youcould get it to work using a utility method that parses the path string, and then attempts to find the various properties within that string. However, that would be a needlessly slow, complex, and error-prone way to find a control.
Whatever it is that you're trying to achieve, you should perhaps reconsider it. I'm sure you'll come up with a simpler solution.

stuck in a loop

Hi

I try to use this piece of code, but the page seems to get stuck in the loop. What am I doing wrong here?

Function NumberOfLinesInFile()
Dim path As String = Server.MapPath("row.txt")
Dim sr As StreamReader = New StreamReader(path)
Dim i As Integer
i = 0
Do While sr.Peek() >= 0
i = i + 1
Loop
sr.Close()
Return i
End Function

Regards

Mhello, what if sr.Peek() is always >= 0 ? check the values returned by sr !!!
The Peek function does not move to the next character, it only consumes it. Try using the sr.Read() instead.

hope this helps,
