WHY?? What on earth does a printer driver need to know about the processes running on a system?
A printer driver has but a single mission in life. Convert drawing commands from GDI/GDI+ to a language used by a printer to describe the same image on a page and communicate status information from the printer back to the spooler. That's it. Nothing else.
Are you installing this "driver" through "Add Printer..." or is this an .EXE your writing? If it's an .EXE, then it's not a printer driver you're writing.

There is no property of the textbox that uses this. You have to handle the Validating event of the TextBox and run a RegEx match of the contents of the TextBox against the RegEx expression you have. YOU have to provide the validation code. It doesn't come standard in the TextBox.
TextBox.Validating event docs[^]

Its pretty rude to post the same question twice, especially when people have taken time out to provide you with a possible solution. 
If you dont agree with an answer just say so rather than re-post the same query. Id say your best bet is to google it because three people have given you the same answer so far.

Hi i am new to vb.net
I am doing one project in vb.net
I want to know how to including Paging concept in vb.net datagrid
There is more records in grid , i want to display 10 records per page and using navigation button user must navigate to all pages
Please help me

I am guessing you are using ASP.NET wne you say paging??
If yes you can view this article:
http://www.codeproject.com/useritems/Custom_Paging.asp
Even you are in Windows form, you can use the same Stored procedure techniques to get the data for paging.
If you want to do Datagrid inbuilt paging, its easy, the worst part of it is it loads all the data at the same time. Just in DataGrid property say:
paging = true and
pageSize = ?
That will do. I prefer custom paging, good for large data.

Try regular expression, there are many for email . Depends how much depth of strictness you are looking for. One of them is below;
^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$
|
|
|
|
|
Add the following using statement to your form:
System.Text.RegularExpressions;
Then use the Regex.IsMatch function like so:
Regex.IsMatch(textBox1.Text, "your regular expression");
This will then determine if what the user has entered into textbox1 matches your regular expression.
I hope this helps.

to reproduce, run the code.
Observed:
System.ArgumentOutOfRangeException was unhandled
Message="InvalidArgument=Value of '0' is not valid for
'SelectedIndex'.\r\nParameter name: SelectedIndex"
t2.c1 contains legal value.
Why this error occurs ?
How to fix ?
:-Ousing System.Windows.Forms;
using System.Data;
using System;
class testForm : Form {
testForm() {
DataTable t = new DataTable();
t.Columns.Add("displaymember");
t.Columns.Add("valuemember");
t.Rows.Add("lower", "l");
ComboBox comboBox1 = new ComboBox();
comboBox1.DisplayMember = "displaymember";
comboBox1.ValueMember = "valuemember";
comboBox1.DataSource = t;
comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;
comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
DataTable t2 = new DataTable();
t2.Columns.Add("c1");
t2.Rows.Add("l");
comboBox1.DataBindings.Add("SelectedValue", t2, "c1");
Controls.AddRange(new Control[] { comboBox1 });
}
[STAThread]
static void Main() {
Application.Run(new testForm());
}
}

A weather control project? Hmmm... Man can't even predict the weather accurately and you want to control it?
On the serious side, no. Word doesn't have an OleDb provider, or any database provider for that matter.

Surely you've heard of Microsoft Weather 2008.

I think I remember seeing a Beta for that about 10 years back. The launch party must have been a total secret!
