Here is a small patch to Form.cs that adds HelpButton property for
displaying the help button in the form title. I've added HelpButton
property, one 'bool' field and changed underlying CreateParams method to
set the WS_EX_CONTEXTHELP window style. I need this patch for
implementation of the FontDialog which will come very soon.
Another question:
I want to make a string from the variable of the FontStyle type but when
I want to check if FontStyle.Bold is included with 'if (style &
FontStyle.Bold != 0) { blah blah; }' compiler gives me an error that it
cannot cast FontStyle enum type to int. How should I check if
FontStyle.Bold and other styles are included?
Cheers,
Aleksandar Dezelin
