This made no sense at all. Are you saying that when this code executes, it's not putting the value of the Text property in the array?? How are you determining this??

You can safely assume that if it runs in 2.0, it will run under 3.5 - the 2.0 framework is "embedded" in the 3.5 framework, so to speak Smile | :)

If you use IEnumerable<t>s and other collections, you may also want to take a look at LINQ. Applied correctly it makes life much simpler

You'll have to enumerate the Control collection of the MdiParent form. Look for a control of Type "MdiClient". When you find it, you can call it's SetBounds method or set it's Location to appropriate values.

For Each c As Control In MyMdiParent.Controls
    If TypeOf c Is MdiClient Then
        Dim client As MdiClient = DirectCast(c, MdiClient)
        client.Location = New Point(...)
        Exit For
    End If
Next

Hi All,
I have a text box in which a file path is displayed. A button to click and open the file. Code executes properly but the file dosent open.
Here is the Code:

Private Sub btnOpen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpen.Click 
        Try 
            strIOPath = ucFile.TxtCode.Text 
            If strIOPath = "" Then 
                ShowMessage("No File For This Transaction") 
                Exit Sub 
            End If 
            If IO.File.Exists(strIOPath) Then 
                File.Open(strIOPath, FileMode.Create) 
            Else 
                ShowMessage("File Not Found") 
            End If 
        Catch ex As Exception 
            ShowMessage(ex.Message)

hi
File.Open(strIOPath, FileMode.Create)

FileMode.Create = Specifies that the operating system should create a new file. If the file already exists, it will be overwritten.

try with FileMode.Open

hi,

if File.Open does not do what you expect, then maybe your expectations are incorrect. Go and check the documentation. That is what it is for.
