Not sure if this is what you're after, but this[^] is a good article on shell autocompletion (its C#, but a class library, so shouldn't matter). Maybe that will help.
Cheers,

Hey, If you are using the dataset then you can access individual field of the dataset using the row and column no. Please explain that exact problem that you are having.

My problem is that i can't display the data in the appropriate textbox & combobox in the forme
Notice that the data is in the dataset.

To set a textbox to have a value from a dataset use:
TextBox1.Text = dsData.Tables(0).Rows(0).Item("ColumnName").ToString
This is to get a specific value out of the dataset. You can also use the textbox.databinding property
To set values in a combobox:
<br />
ComboBox1.DataSource = dsData.Tables(0)<br />
ComboBox1.DisplayMember = "Name of Column to DISPLAY"<br />
ComboBox1.ValueMember = "VALUE of the Column"<br />
You would then have to set the selected item of the combobox to be the current record's.
Is this the information you were after?

Try this...

TextBox5.DataBindings.Add("Text", ds.Tables("Mouch"), "التاريخ")
I am assuming that "التاريخ" is an Item of the Table "Mouch"

Yes "التاريخ" is an Item of The Table "Mouch"
but the statment you just give me didn't work.
and to be sure that the dataset contain the appropriate table with the appropriate column i put some message to give the data inside:
Dim dt As DataTable
For Each dt In ds.Tables
'msgbox(dt.tablename)
Next
Dim dc As DataColumn
For Each dc In ds.Tables("mouch").Columns
MsgBox(dc.ColumnName)
Next
Dim drw As DataRow
For Each drw In ds.Tables("mouch").Rows
MsgBox(drw(1))
MsgBox(drw(2))
MsgBox(drw(3))
Next()
and all give me the right data
with my best regards

The code I posted should work for your databinding.
If not, the only other thing I can think of is it dont like the Characters التاريخ . Try replacing them characters with the actual integer index of the column if you know what that would be.

I go far,and i change all the database to an English one but no satisfied result, (i think if it's not written in english it cause trouble).
also i put instead of the name of the field his number, nothing different.
The think that make me confused in this problem that there no one give a real example about using this features without using the wizard to create the adapter,connection and the dataset, and if you try this using the wizard it done well.
With my best regards

I want to validate a text box, that it only accept the numeric characters on key press/key down event. I dont want message boxes when any alpha character press.

you need to handle your textbox's keyboard events, either keydown, keyup or keypress. Then check the contents of the textbox and delete any characters you don't want.
make sure you set the maxlength property because otherwise this will take some time
/jason

Can you please specify how this can be done. Sample code will be very useful.
With Best Regards,
Mayur

you can handle as follows
add keypress event to the textbox and add following code
If Char.IsNumber(e.KeyChar) Then
e.Handled = False
Else
e.Handled = True
End If
end if
happy programming

I am affraid there isn't a single statement to solve this issue but probably as you know you can set the content's text alignment to right or to left one by one as follows:
Label1.textalign = contentalignment.middleleft
Never give up!

First confirm that gird should have 10 rows and start the loop with 1 may be grid index starts from 1.....
For intCount = 1 To 10 'Start with 1 instead of 0<br />
grid1.Cell(0, intCount).Text = "Hello"<br />
Next
Regards

First, there is no .NET version of the MSFlexGrid. It's just an old ActiveX control that you can still use in your app though.
How many row does your grid have? Your loop says there are 11, number 0 trough 10. If you do have 10 rows, they'll be numbered 0 through 9.
For intCount = 0 To 9
grid1.Cell(0, intCount).Text = "Hello"
Next

Hello welbert,
There was a Microsoft FlexGrid for VB 6, but it should still be available in .NET, although it will probably not . Is this what you are using. It was based on an old version of our VSFlexGrid. We, ComponentOne, also have an updated FlexGrid for .NET 1.x and 2.0. I am not sure which one you are using, but each version has the rows indexed from 0, so you are right to start intCount at 0. Keep in mind that 0 to 10 is 11 rows, not 10 rows. If you want to add "Hello" to all rows, it would be better to use
For intCount = 0 to Grid1.Rows.Count -1
Grid1.Cell(0, intCount).Text = "Hello"
Next
This way you know that the index will always be in range, even if rows are added or deleted later. If you still have trouble, please let me know exactly which grid you are using, and which build, then I can provide better assistance.
