Hello
I'm sorry my reply came very late, but your email notification arrived to my just now!!
You can't acess ctl this way because you've declared it as a local variable in a method. Declare it as a public member in your class, and access it like MyCustomColumn.ctl.Click for the click event as an example.
I don't know if my reply would help you or it came too late, but forgive me.

da1.Fill(ds, "Autores1")
Dim dv As New DataView(ds.Tables("Autores"))
dv.RowFilter = "Au_ID <= 15"
DataGrid1.DataSource = dv
End Sub
however, i think it`s all that i need

Maybe Delete() and CancelChanges() on the underlying row ?

You can configure it in SQL Server
only two letters away from being an asset
|
|
|
|
|
You can write a WindowsService and make this service start your processes whenever you want (in this case when the DateTime.Minute = 0)..
not an expert suggestion just an idea

*sigh* buy a book, and work through it. You're never going to learn if you come to these forums without the slightest idea of how to apply the things people tell you.
If you double click on a button in the designer you will create an event for the click. What do you want the class to do ? You can have an instance as a member variable, or create a local instance in that class, and call it.
If you have results from the class and want to show them, the easiest way is a messagebox, otherwise you need to create a new form class. If you do this, unless the operator class instance is a member for some reason, I'd do the operation inside that form, so your event just shows the dialog and the form itself performs the operation and shows the result. Otherwise, I'd pass the result through the constructor.
And again, if you don't know what any of that means, buy a book and work through it.

and then can access public members and public methods of class operator

Hi All,
I am using MDI form, The first 20% of the form am displaying Treeview control and in the rest of the portion am displaying a mdiChild form. The mdiChild form has got few UI controls on which tab order is set.
Now the issues is, when we hit on tab, it revolves within the child form. How can i make it to go to treeview control once the last control on the child form is focus? ie. on being on the last control and hit tab, the focus should go to the treeview.
Any help is highly appreciated.
Thanks in advance for any guidance and suggestion
Regards
Kais

Hello
In that last control, handle the KeyUp event
private void MyLastControl_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyData == Keys.Tab)
MyTreeView.Focus();
}

Hi,
When i get data from a device which is attached to my serial port, its cutting it off after like 20 characters.
This is how it would look like:
afsdfagfsdgsdagf
asgdasdfdsafgafa
gasdfasdgadsfsdv
gasdffbzxxcvfads
But i don't want it to cut it off, how can i fix this so it would look like this:
afsdfagfsdgsdagfasgdasdfdsafgafagasdfasdgadsfsdvgasdffbzxxcvfads
Thanks in advance!

Replace System.Environment.NewLine with an empty string?
string x = stringFromSerialPort;
string modifiedString = x.Replace(Environment.NewLine, "");

Hello
Handle the CheckedChanged event, then this:
private void MyCheckBox_CheckedChanged(object sender, EventsArgs e)
{
if(MyCheckBox.Checked)
{
MyTextBoxA.Visible = true;
MyTextBoxB.Visible = true;
}
else
{
MyTextBoxA.Visible = false;
MyTextBoxB.Visible = false;
}
}
That's it! So, where is the question now??:->
Regards
