The System.Networking.Messaging.EmailVerification class, of course! It has a static method, "Verify" that will tell you whether any text string is a valid, active email address. It doesn't even have to access the internet to do so - amazing bit of code actually.

It wasn't my sarcasm detector I was questioning. What would the OP think about that post?

Your Qestion have many faces one of the
1-You mean is it really exit or fake email address that have valide format but dos not exit in reallity
on i think you can send send test mail message and chech the response or make user reply to your message to complete his subscribtion to newsletters
2-You mean this email address have subscribe before or not
if you store those email address in db or xml file or any thing you can search for it in those data store
3-You mean the validation like above response said
and you can use regular expression as if it is not valide
it will be not exist

There is no function to verify an email address. Ever sign up for a subscription or anything? You'll get a confirmation email that says something like, "click on this link to validate your email address." This is the system verifying that your email address is valid. There's really no other way to do it.

I want to add a panel from a menu item, my problem is that if i dock the panel to the right, it will push my toolbar and statusstrip to the left and occupy their space, same with docking to left but oposite offcourse. If i dock it down it will go below my statusstrip and push it up, and if i dock it up it will do the same with my toolstrip. The only docking that works "properly" is fill. How can i have my panle docked to an edge without it moving my status- or toolstrip around?
Here is the simple code i use:
Panel myPanel = new Panel();
myPanel.Dock = System.Windows.Forms.DockStyle.Fill;
myPanel.Location = new System.Drawing.Point(0, 49);
myPanel.Size = new System.Drawing.Size(200, 408);
this.Controls.Add(myPanel);

Add one more Panel with DockStyle.Right and add the toolbar and statusstrip to it. Then add the new Panel as above.

I read before, But i couldnt move on cells with direction keys. What do you advise for that?
|
|
|
|
|
Following points may help
(1) Please Subclass the TextBox displayed.
(2) Override the PreProcessMessage and Fire a custom event on the -> (right arrow event).
(3) Subscribe to this event in the ListView. In this method just change the focus to the next TextBox.

I create a datatable with 3 columns at run time and set it to a Datagrid. Datagrid has 5 extended columns. for example one is numeric column, other is a date time picker, other is button.
I aim to create as a form like EXCEL but with special columns.
I add a row to datatable after creating. I want to add others when the user fills all fields or press down key.
I couldnt achive yet, there is always problem, Could u advise another method to do that?

o buy a third party datagrid library that isn't as brain dead as the built-in version.
o look at some of the nicer controls on this site (http://www.codeproject.com/cs/miscctrl/csharpgridcontrol.asp[^])
o waste many hours of your life researching the functionality of the builtin datagrid, determine that it sucks, and end up doing one of the above two things anyway.

Please don't double post.
If you really really think that you have to draw attention to your question in more than one board, keep the question in one board, and post a link to it in the other.

The Graphics object gives you all the methods you need to draw onto a Bitmap. Check MSDN for more info. You should draw it to the screen in your OnPaint handler, and call Invalidate for force a redraw when it changes.
