An application sends an EM_SETPASSWORDCHAR message to set or remove the password character for a single-line edit control when the user types text. When a password character is set, that character is displayed in place of each character the user types.


wParam = (WPARAM) (UINT) ch;    // character to display 

lParam = 0;                     // not used; must be zero 



Value of wParam. Specifies the character to be displayed in place of the character typed by the user. If this parameter is zero, the characters typed by the user are displayed.

Return Values

This message does not return a value.


When the EM_SETPASSWORDCHAR message is received by an edit control, the edit control redraws all visible characters by using the character specified by the ch parameter.

If the edit control is created with the ES_PASSWORD style, the default password character is set to an asterisk (*). This style is removed if an EM_SETPASSWORDCHAR message is sent with the ch parameter set to zero.
