Hi
I want to display a control(ListView) inside the datagrid view
So the problem I encounter r:
1.How to get the Top & Left of the cell underneath I want to display that List View
2. If I add that List View with
me.datagridview1.controls.add(Lisview)
Listview.setBounds(hti.ColumnX,Hti.RowY,100,100)
But this is also not suceeded Properly
Then the control at the last or last to last row Cuts
As the ListView does not get the proper Space to occupy
Should I add that control to form Rather than DataGridView
But then how to Show the list view correspondingly with Datagridview cells (Like every cell in the Column2 has a image Clik on that iamge will show LisView underneath that cell)
Thanks For this Help

Hello!
I don't know how I can make an entry in to WAB (Windows Address Book) and how I could check if the entry I am intending to make is already exist or not.
I am seeking Vb.NET code samples about WAB and It has been for days I haven't found any.
If you help me to work it out, I would really appreciate it!
Thanks!

Thanks Jason!
Kwab is not a solution for me. I need to have the full source code in VB.net. There are some written in C++ but I do not have any knowledge about C++ language.
If youcome cross it to somewhere would you please let me know because it has been over 5 days I couldn't find a sample code of it in VB.net
The life is an unknown cirle and we are the dot in it!

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.

I'm using the DataAdapter & the DataSet without using the wizard, but the problem that occured with me that i can't display the content of the Database in the appropriate textbox and combobox.
knowing that i verify if the connection is well established and the dataset contain the right data.
with my best regard;)

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
