Syntax
EM_SETPASSWORDCHAR wParam = (WPARAM)(UINT) ch; lParam = 0;
Parameters
ch
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
None.
Remarks
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.
