Then maybe it should be called StringHolder or StringContainer

It doesn't contain a string, it is a string. Well, actually it's a reference to a string, but that's implied as reference type variables always are references.

It contains a line of text. What's wrong will calling it "line"? Smile | :)

This works like a charm Big Grin | :-D

THANKS

Now for another question...

Is there any way to input horizonaly in a Listview box?
Or is this just a matter of Formatting?.
All my data is going down instead of across.
I am viewing the Listview Box with Details set as true and Columns Headers ready and waiting.

Yes, you would first add an item (the leftmost item). The 'Add' method returns a listviewitem so you can get a reference to it by writing this:

Dim item As ListViewItem = ListView1.Items.Add(StringReader)

Then to add an item to the next column you would use this:

item.SubItems.Add(SubItem)

That's basically what you need to know.

THANKS Again Cool | :cool:

Have just been doing some more reading about Listview Boxs and have just figured out that what you have said is what i need to do.;)

This is my Code so far.....

Do While Not FileReader.EndOfStream
      StringReader = FileReader.ReadLine
      Form2.ListView1.Items.Add(StringReader)
      'Adding Subitems
      Dim item As ListViewItem = Form2.ListView1.Items.Add(StringReader)
      Dim i As Integer
      For i = 0 To 5
          item.SubItems.Add(StringReader)
      Next
  Loop

Just a little bit of fine tuning.... Smile | :)

What is happening is that the first item on the left is in the right spot, after that what should be the first sum-item it duplicated in the left column.
Then in the 3rd row this same item is in all the sub-item columns.
And the same thing happens to all the other sum-items, which then knoks out of wack all the other data.

It is surprising how writing something out and then thinking about it , you can come up with an answer;) D'Oh! | :doh:

AND THE ANSWER is :-

move the Stringreader line into the for next loop and get rid of the line :-
Form2.ListView1.Items.Add(StringReader) as you don't need it twice in the code.

I doubt it, since it would probably be another drain on the battery. Check the specs on the one you're looking at. The bigger problem would be are there USB devices out there that support being attached to a PDA...

The easiest way to do this, is to write both forms as controls, put both controls on your one form, and change which control is visible. The other way, is just to set the initial form's Visible property to false when you open the form, and true when it's closed again.

You could also consider setting the opacity of the form to 0% if hiding and re-showing the form causes problems wih Form_Activate if you are using it.

so the form that needs to show when you close the other form place it like master form like startup form and then type this in load event in that form:

dim f as new form2()
me.hide()
f.showdialog()
me.show()

thats all...

but if you want to show form only if button is clicked then place on other form form2 one checkbox name it "chx" and type like this...

FORM 2
--------------------
public sub button1.click .... ' example button close form
chx.checked=true
me.close
end sub

public sub button2.click .... ' example button end program
chx.checked=false
me.close
end sub
-----------------------

FORM 1 STarting form
-----------------------
dim f as new form2()
me.hide()
f.showdialog()
if f.chx.checked=true then
me.show
else
end
end if

like that enyoj and hope it helps.... D'Oh! | :doh:

Are you talking about a Windows Forms DataGrid or the Web Forms DataGrid?

If you mean like a firewall does, then no. It takes driver level code to do this. Something that VB.NET, or managed code in general, is not suited for.

VB.NET, C#, ... About the only language that doesn't target the .NET Framework natively (Managed Code) is Visual C++.
