Instead of copy paste a unicode character or setting it in the code-behind you could also change the properties of the TextBox  Simply set  UseSystemPasswordChar  to True and everytghing will be done for you by the Framework  Or in code-behind   this txtPassword UseSystemPasswordChar   true

I was also wondering how to store it cleanly in a variable  As using   char c            is not very good practice  I guess   I found out the following way of storing it in a variable  char c    char 0x2022    or 0x25cf depending on the one you choose   or even cleaner  char c     u2022     or   u25cf    https   msdn microsoft com en-us library aa664669 28v vs 71 29 aspx  same for strings  string s     u2022     https   msdn microsoft com en-us library 362314fe aspx

Below are some different ways to achieve this  Pick the one suits you   In fonts like  Tahoma  and  Times new Roman  this common password character     which is called  Black circle  has a unicode value 0x25CF  Set the PasswordChar property with either the value 0x25CF or copy paste the actual character itself  If you want to display the Black Circle by default then enable visual styles which should replace the default password character from     to     by default irrespective of the font  Another alternative is to use  Wingdings 2  font on the TextBox and set the password character to 0x97  This should work even if the application is not unicoded  Refer to charMap exe to get better idea on different fonts and characters supported
