row++)<br />
{<br />
string line = sr.ReadLine();<br />
<br />
if (row >= this.c1FlexGrid1.Rows.Count)<br />
this.c1FlexGrid1.Rows.Count++;<br />
<br />
int col = this.c1FlexGrid1.Cols.Fixed;<br />
string[] cells = line.Split(' ');<br />
for (int c = 0; c < cells.Length; c++)<br />
{<br />
if (col >= this.c1FlexGrid1.Cols.Count)<br />

Which bit are you stuck on ? I don't think VB.NET supports 'using', that just means you create the object, and call Dispose at the end of your code block.

Let me see how I go...
Dim row as int =
this.c1FlexGrid1.Rows.Fixed;<br />
<br />
while (sr.EndOfStream = false)<br />
<br />
dim line as string = sr.ReadLine()<br />
<br />
<br />
if (row >= c1FlexGrid1.Rows.Count) then<br />
c1FlexGrid1.Rows.Count++<br />
<br />
dim col as int = c1FlexGrid1.Cols.Fixed<br />
<br />
dim cells as string() = line.Split(' ')<br />
<br />
dim c as int<br />
<br />
for c = 0 to cells.Length<br />
<br />
if col >= c1FlexGrid1.Cols.Count then<br />
c1FlexGrid1.Cols.Count++<br />
<br />
c1FlexGrid1(row, col) = cells(c);<br />
col++;<br />
end for
<br />
row = row + 1<br />
<br />
end while<br />
<br />
A bit of a guess, but I'd say this is more suited to the while loop anyhow.<br />

Ooops - I left a 'this'. this is me in VB.NET. As in me.Invalidate() - isn't it just the cutest thing ?

VB does have a 'using' equivalent. The equivalent VB is the following produced with Instant VB - note that the inner loop could have been converted to a VB 'For' loop instead as Christian's post indicated:
Dim fn As String = "c:\temp\data.txt"
Using sr As System.IO.StreamReader = New System.IO.StreamReader(fn)
Dim row As Integer = Me.c1FlexGrid1.Rows.Fixed
Do While sr.EndOfStream = False
Dim line As String = sr.ReadLine()
If row >= Me.c1FlexGrid1.Rows.Count Then
Me.c1FlexGrid1.Rows.Count += 1
End If
Dim col As Integer = Me.c1FlexGrid1.Cols.Fixed
Dim cells As String() = line.Split(" "c)
Dim c As Integer = 0
Do While c < cells.Length
If col >= Me.c1FlexGrid1.Cols.Count Then
Me.c1FlexGrid1.Cols.Count += 1
End If
Me.c1FlexGrid1(row, col) = cells(c)
col += 1
c += 1
Loop
row += 1
Loop
End Using

I've been saving my datatables with .writexml
However, sometimes I create a dataview from the datatable and then allow the user to filter the dataview.
But now I want to save the filtered data back to .xml
How can I get the dataview back into the datatable? Do I have to go row by row?
Thanks in advance, as always

Use a thread class that allows sending information to the main thread, and use that to display your status.

It there some sort of test to see if you are in design time for VB.Net? I am having a problem where I need a bit of code to be executed at run time...but it is going to be invalid in my control at design time
Using theAdaptor As New DSEmployeeNamesTableAdapters.GetAllEmployeeNamesTableAdapter
DsEmployeeNames1.Merge(theAdaptor.GetData(Common.CurCompany.ID))
End Using
At design time 'Common.CurCompany.ID' has not yet been set, but at runtime it will be valid...any suggestions? Maybe a preprocessor symbol I could use to pass to
<Diagnostics.Conditional("")>?
Thanks ahead of time for any help

Yes, it's DesignMode, from memory. It doesn't always work. The new designer sucks.

Set the datasource to be your datatable, then set the DisplayMember property to be 'Customername'

They are generally passed as a string array to your program's entry point, although it wouldn't surprise me to find they are also a property of the Application object.

I didn't really read all of your post, it really get tiresome when you make every other word bold, but here is page where you can see examples of connection strings:

Sir/Madam,
I have a table , having two fields , first for name and second for roll number.I don't have serial number field in that table.Can , I display Serial number field in the datagridview , with those two fields.
I mean if i have ten records in the table. Then datagrid should display record no for each row, like for first row it should display 1 , and for second row , there should display 2 and so on.This should happen in the extra column in the datagridview.Is it possible.
Please help.
Thanks and regards
Pankaj

Hi,
You can use sql query in this case. If your current sql query is -
select name,rollno from students
Then modify the query as -
select 0 as [Serial No.],name, rollno from students.
This modified query will generate a column named Serial No. whoes rows will be filled by 0. Then in the program use a counter to count the rows, in the RowDataBound event handler. Replace the text in column 0 with the counter value. You will get your desired resutls.
Hope i am clear enough.
I am assuming that you are using SQL Server as database.
