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!

Hi experts,
I have an urgent issue that need to be fixed ASAP. Anyone of you know how to open cash drawer using C#.net 2.0. I'm using Epson receipt printer TM-U220 which is connecting to the cash drawer. The printer is using LPT port.
I found a few resources Eg http://support.microsoft.com/kb/322091 , but still could not make the cash drawer open.
Appreciated if anyone of you could guide and provide me some information regarding this.
Thanking you in advance.

Ok, thank you very much. I'll try to access the information there.

No problem
I'd have dug up a code sample for you but all my EPOS code is at home

Really? Thank you very much. Appreciated if you could share with me your code sample ASAP.

I have several mouse buttons that on a mouse click they call the same function, but I need to know which button was pressed.
Is there are way to determine this?
private: System::Void btnTmOut_Click(System::Object^ sender, System::EventArgs^ e) <br />
{<br />
...Bunch of code...<br />
if(btn1)<br />
x = 0x0001;<br />
else if(btn2)<br />
x = 0x0001;<br />
...<br />
else if(btn8)<br />
x = 0x0008;<br />
...Bunch of code...<br />
}
Thanks

The sender parameter should hold a reference to the button that caused the event to be raised. You should cast it back to a Button before using it. To follow the psuedocode you have in your question, you would want to make sure each button has a distinguishing name and test the Name property. You could also use the Tag property, but you will still end up doing string comparisons.
What is the reason you have all of the buttons going through the same event handler? If each button does something different you are better off sending them to different event handlers. If there is common code (like logging) that needs to occur, refactor that into a separate method and have each event handler call that method at the appropriate time.

Thanks it works great. Here is my final code. This greatly reduces the variables that have to be shared in the class.
private: System::Void btnTmOut_Click(System::Object^ sender, System::EventArgs^ e) <br />
{<br />
...<br />
Button ^btnLocalOnly = (Button^)sender;<br />
...<br />
if(btnLocalOnly->Name == this->btnTmOut1->Name)<br />
x = IO_1;<br />
else if(btnLocalOnly->Name == this->btnTmOut2->Name)<br />
x = IO_2;<br />
else if(btnLocalOnly->Name == this->btnTmOut3->Name)<br />
x = IO_3;<br />
else if(btnLocalOnly->Name == this->btnTmOut4->Name)<br />
x = IO_4;<br />
else if(btnLocalOnly->Name == this->btnTmOut5->Name)<br />
x = IO_5;<br />
else if(btnLocalOnly->Name == this->btnTmOut6->Name)<br />
x = IO_6;<br />
else if(btnLocalOnly->Name == this->btnTmOut7->Name)<br />
x = IO_7;<br />
else if(btnLocalOnly->Name == this->btnTmOut8->Name)<br />
x = IO_8;<br />
else<br />
{<br />
}<br />
...<br />
}

Hi,
I want the user to order a list of items. What I had in mind was a control similar to a ListBox, where the user can click-and-drag items into the order they need. This is a fairly common operation, but I was unable to find a predefined control doing this. Any help?
thanks..
