Hi Everybody,
I'm using VB to create a stand alone application.
I want to delete some data item from Combo box & List Box.
I've done this.
When I try to delete any data item from the combo or List box, its deleting.
But the problem is when I re-open the same application the deleted item is also displaying in the list box & combo box. But I don't want it to be like that.
How ever this application was not connected to Database.
The list present in the Combo box are added at the Design time.
Could anybody help me please....?
Thanks & regards,
Prem

Its because you are not deleting the item from the source of list where list and combo boxes are populating, or from the code.
You need to use either filing or database or you can use windows registry to do this otherwise the way you are using is impossible to delete some item permanently. :)

What is the source of data for Combo box & List Box.
is that being populated from database ? or hard coded ?
if that the case you need to delete from database as well while deleting from the control.
if hard coded need to modify the code.
@debasisdas
I directly provided values to Listbox & Combo box @ design time. Not using code or Database. Because these boxes contains only few data items. (around 8 to 10).
ThanQ for showing interest sir.
Please reply me.
You are hardcoding the items. Save all items in a file and at runtime populate your control from that file...
@EYE4U
Yes, Please tell me how to save those items in a NOTEPAD file instead of MS Access & how to retreieve & delete those items.
Please help me..
If you dont know File systems it ll be better to use MSAccess instead of using files...
Whatever i ll upload an example...

@EYE4U
Yes, I was doing the same thing. Anyhow thanks for your kind co-operation.
& if you don't mind, will you please send a sample code for editing data present in DataGrid Control...? I am also using that Datagrid which is connected to Database, but I couldn't find how to edit.
I m sorry for replying late.... I was sick actually... :)
In the example i have used fso to save the list..

ARUZ

next new record say Record2 and the combo box should just display only
9999 values. I am trying to do this, just...

Hi all,
Could you tell me the best way to add a blank item(as first item) in a data
binded combo box? Because I think I didn't do it right and it generate an
error if the second item(after the top blank item) is selected by using
Combo.SelectedValue :
"Specified argument was out of the range of valid values.
Parameter name: '-2147483648' is not a valid value for 'index'.

I have a data bound combo box. The combo box displays several items (status
code descriptions). After the combo box is bound, I want to set the combo box
so that the "Draft" status is displayed by default. Since the data originally
comes from a database I don't know which position in the combo box it will be
and I don't want to hardcode the status_code field (I want to select the
combo box item based upon status_desc).

The .NET 2.0 documentation states the following:
When using a DataSet or DataTable in conjunction with a DataAdapter & a

the row. The Delete method marks the row as Deleted in the DataSet or
DataTable but does not remove it. Instead when the DataAdapter
encounters a row marked as Deleted, it executes its DeleteCommand
method to delete the row at the data source. The...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
