I have used several code for email validation like
{string pattern=@"^[a-z][a-z|0-9|]*([_][a-z|0-9]+)*([.][a-z|" +
@"0-9]+([_][a-z|0-9]+)*)?@[a-z][a-z|0-9|]*\.([a-z]" +
@"[a-z|0-9]*(\.[a-z][a-z|0-9]*)?)$";
System.Text.RegularExpressions.Match match =
Regex.Match(txtEmail.Text.Trim(), pattern, RegexOptions.IgnoreCase);
if(match.Success)
MessageBox.Show("Success");
else
MessageBox.Show("Fail");
}
// But it is not working .It gives a run time error like argument exception.Please help me out ASAP.
Thanks & Regards
Sayantan Basu.

I have written following code but It is not displayed on the form
pictureBox1 = new System.Windows.Forms.PictureBox();
pictureBox1.Location = new Point(Wnd[18].Left + 2, Wnd[18].Top + 2);
pictureBox1.Name = "pictureBox1";
pictureBox1.Size = new System.Drawing.Size(80, 40);
pictureBox1.Image = new System.Drawing.Bitmap("c:\\bitmap1.bmp");
pictureBox1.Show();
pictureBox1.BringToFront();

you have to add the control to the form
Form1.controls.add(picturebox1);
|
|
|
|
|
Have you forgot formObject.Controls.Add(pictureBox1)?

Hi all,
The garbage collector runs in specific intervals(hope i am correct), and during this it collects all variable and dispose them when they becomes out of scope or not referred any more.
a) In a particular Method() if i am creating many variables, then is it possible to dispose them all before exiting that method ?
b)Suppose i have a method and inside this many methods, this MethodX execute till the last G() got executed and then it returns control to calling one.
MethodX()
{
A();
B();
.
.
.
G();
}
But somehow its slowing the execution, Is it possible that all methods executed independently/simultaneously/parallely?
regards,

It runs whenever cleanup is required.

If your variables are not referred and GC ran, it will get *collected*.

Are you asking how to execute these methods in parallel? If yes, you need separate threads to execute each method. I am not sure how this is related to your actual GC question.

A manuall call to GC.Collect is not recommended because it will do a full memmory compaction after the the collection process.. if you are using any heavy objects...Probably you can set is as null after use.. GC will get triggered only when the memmory pressure is more for a particular allocated heap. or when the allocated threashold limit is reached.
You can used threading. But only after a good analysis upon your method structure ( that whether it is taking any input from the previus one) and requirement.. Remember Threading is there to use the CPU Idle time.it will take more time if it does't have any.
