How to display a help file on top of a form with style fsStayOnTop (Views: 27)
Problem/Question/Abstract: I have a form with its formstyle set to fsStayOnTop. If I display the help for this form, the help windows is opened behind my form. Even if I click on the help window it stays behind. How can I display the help windows in front of any form? Answer: You can do this by sending a macro to WinHelp. procedure TForm1.Button1Click(Sender: TObject); begin with Application do begin Helpfile := 'C:\Programme\Borland\Delphi5\Help\TOOLS\HCW.HLP'; HelpCommand(HELP_CONTENTS, 0); HelpCommand(HELP_COMMAND, Integer(PChar('Generate(' + IntToStr(WM_COMMAND) + ', 1471, 0)'))); end; end; This macro call fakes a menu action for the "keep on top" menu item. Use 1472 to deactivate the on top state. Help macros are documented in the helpfile I used above. The HelpOnTop macro gives the menu IDs to use for Generate in this case. HelponTop itself may be useful if you simply want to change the current on-top default for the window (it is a toggle). |
