To restore an application from "minimize to system tray" mode to "Normal" mode (visible) from another application, I am using "Showwindow " method of "user32.dll ". The API is working as expected i.e. displaying the application on Normal mode.
Moreover, I want to remove that application's System tray icon as soon as its mode changes from "minimize to system tray" to "Normal".

Looking for the best way to parse a phone number (in a 3-3-4 format) from a string..
The string may contain a lot of junk information on the line.
If there is a code following the phone number then I also want to pick that up.

Code:

For example 
String1 = "This is string 1 and here is my phone number 123-456-7890"

String2 = "String 2 is 123-456-7890USA"

Hi, I have a list of accounts in my list view. I total these and add a new item to the list view. I have changed the font on this to bold but is there a way to add a border around this one item only?

I know it can be done in a datagridview, but can it also be done in a list view?

Thanks for any help :)
