This is not what you need to do at this point. You want to figure out if the file exists. The FileDialog.CheckFileExists Property[^] however only specifies if the dialog should warn the user if the file does not exist. What you need here is the File.Exists Method[^].

kobezt08 wrote:
txtSAPsrc.Text = openFiledlg.FileName

When naming your fields in VB.NET don't use the old VB Object Naming Conventions[^] with prefixes. Use the new Design Guidelines[^] instead no matter which programming language you use.

kobezt08 wrote:
FileOpen(1, openFiledlg.FileName, OpenMode.Input)

I recommend to use the base classes from the System namespace (personally, I think the whole Microsoft.VisualBasic namespace is only about backwards compatibility). Therefore the appropriate object would be an instance of the StreamReader Class[^].

kobezt08 wrote:
mitem = New ListViewItem(str.Split(","), 0)
lstvReport.Items.AddRange(New ListViewItem() {mitem})

I don't know if there is a more elegant way but I suggest to create a new ListViewItem[^] with all the belonging sub items and add that to the ListView.Items[^] collection. Also don't use str.Split(",") but str.Split(","c) because the first version won't compile with Option Strict[^] on (Option Explicit[^] should be switched on too).

After some additional declarations...

Dim InputReader As StreamReader
Dim InputLine() As String
Dim Counter As Integer

...my suggestions looks like this:

If File.Exists(openFiledlg.FileName) Then
  flag = True
  txtSAPsrc.Text = openFiledlg.FileName

  InputReader = New StreamReader(openFiledlg.FileName)
  Str = InputReader.ReadLine()

  Do Until Str Is Nothing
    InputLine = Str.Split(","c)
    mitem = New ListViewItem(InputLine(0))

    For Counter = 1 To InputLine.Length - 1
      mitem.SubItems.Add(InputLine(Counter))
    Next Counter

    lstvReport.Items.Add(mitem)
    Str = InputReader.ReadLine()
  Loop
End If

Thanks so much for all th ehelpful tips....
Just 1 more question how do i set the data to be displayed on select colume?

example: iI wish to put "000189" in the 1st colume and "SUPERSTAR VIRGO" on like 5th colume.

And btw in str.Split(","c), wat is the c stand for & wat does InputLine(0) do, cos i cant find info on InputLine() on msdn? Char?

Since we're just adding items to a collection and we can't directly replace the collection itself (the ListViewItem.SubItems Property[^] is read-only) I guess the only possibility is to throw in some extra (empty) items. Try adding some of these:

mitem.SubItems.Add(New ListViewItem.ListViewSubItem)

kobezt08 wrote:

The c tells the compiler that the character is a char and not a string (see Visual Basic Language Reference: Char Data Type[^]).

kobezt08 wrote:

Nothing. Just an array of strings I declared.

Best regards

You really can't. There are libraries out there that will help with this, but they cost $ and are not fool proof solutions.

I really can't understand your question, but the method you should use to store data would have already been covered in your class...

Hi all:
Text substitution and some basic text operations in MS Word with large amount of Docs can be both time-comsuming and effort-consuming, and you easily get exhausted.
I want to apply a VBA code applet which can delete the space between a Chinese character and English letter, for example "非_f" becomes "非f", but I don't know how to recognize the Chinese character and English letter by code. Can anybody provides a solution?
The following code might help!

Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
With Selection.Find
.Text = ") 。"
.Replacement.Text = ")。"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchByte = True
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
End With

Not support by the DataGrid. You'll have to find a 3rd party component that supports it. No, I don't know of any...

You can use SetWindowsHookEx API to monitor mouse and keyboard action.
There are many application doing the same thing you plan to do. Ex: MSN Messenger, SpyXX, Screen Saver...
