Larry, If you use "RunDemos" (included with Win32Lib) to look at "MsgBox" example, it will show you how to make multiple lines in a Message box. Following is that same example re-made into a "Template" which I will include with my "Template Handler". (It seems likely "CrLf" is not actually needed, just linefeed, as others have mentioned.) Dan Moyer -- Creating a WINDOWS MESSAGE BOX -- you can create a "standard" Windows message box -- containing various icons and user choice buttons, -- and you can test for what the user clicks on in it. -- start with: result = message_box( -- followed by text enclosed in quotation marks; -- (separate lines can be created by using "& CrLf & " after each line) -- put a comma after the text; -- followed by a TITLE for the message box in quotes, -- followed by a comma; -- following the comma after the title is a value which sets up -- various buttons in the message box as well as other displayed items; -- the value can be made up of various constants defined in Win32Lib, -- which are described below; -- they can be ADDED together with the "+" operator, -- as shown below; -- if the value is zero, a SIMPLE message box is created. constant CrLf = { 13, 10 } -- carriage return/linefeed -- this procedure should be made to be called by whatever event should -- display the message (an error, information, "about" a program, etc) procedure OnClick_MsgBoxButton() atom result result = message_box( " This is some text in a Message Box;" & CrLf & " you can put line after line of text here," & CrLf & " practically as many as you want" & CrLf & CrLf & " It will expand to a certain degree to fit long lines," & CrLf & " but if your lines get really really really long like this one then it will reach some maximum width and then put some of your text on a new line." & CrLf & CrLf & " It's generally better to use shorter lines," & CrLf & "so you don't exceed the line length of the interpreter.", "MESSAGE BOX", -- THE TITLE OF THE MESSAGE BOX 0 ) -- STYLE VALUE FOR VARIOUS BUTTONS ETC end procedure onClick [MsgBoxButton] = routine_id("OnClick_MsgBoxButton") -- MB_ICONQUESTION+MB_YESNOCANCEL+MB_TASKMODAL -- which results in showing a question mark icon, with yes/no/cancel buttons, -- and the box must be closed by the user before anything else can be done -- Possible style values for message_box() style sequence: -- MB_ABORTRETRYIGNORE = Abort, Retry, Ignore -- MB_APPLMODAL = User must respond before doing something else -- MB_DEFAULT_DESKTOP_ONLY = #20000, -- MB_DEFBUTTON1 = First button is default button -- MB_DEFBUTTON2 = Second button is default button -- MB_DEFBUTTON3 = Third button is default button -- MB_DEFBUTTON4 = Fourth button is default button -- MB_HELP = Windows 95: Help button generates help event -- MB_ICONASTERISK = Lowercase letter i in a circle appears -- MB_ICONERROR = A hand appears -- MB_ICONEXCLAMATION = Exclamation-point appears in the box -- MB_ICONHAND = A hand appears -- MB_ICONINFORMATION = MB_ICONASTERISK = Lowercase letter i in a circle appears -- MB_ICONQUESTION = A question-mark icon appears -- MB_ICONSTOP = MB_ICONHAND -- MB_ICONWARNING = MB_ICONEXCLAMATION -- MB_OK = Message box contains one push button: OK -- MB_OKCANCEL = Message box contains OK and Cancel -- MB_RETRYCANCEL = Message box contains Retry and Cancel -- MB_RIGHT = Windows 95: The text is right-justified -- MB_RTLREADING = Windows 95: For Hebrew and Arabic systems -- MB_SERVICE_NOTIFICATION = Windows NT: The caller is a service -- MB_SETFOREGROUND = Message box becomes the foreground window -- MB_SYSTEMMODAL = All applications suspended until user responds -- MB_TASKMODAL = Similar to MB_APPLMODAL -- MB_YESNO = Message box contains Yes and No -- MB_YESNOCANCEL = Message box contains Yes, No, and Cancel -- you can test for user actions by testing the return value from the -- message box function. -- possible values returned by MessageBox() -- 0 means failure -- IDABORT = 3, -- Abort button was selected. -- IDCANCEL = 2, -- Cancel button was selected. -- IDIGNORE = 5, -- Ignore button was selected. -- IDNO = 7, -- No button was selected. -- IDOK = 1, -- OK button was selected. -- IDRETRY = 4, -- Retry button was selected. -- IDYES = 6 -- Yes button was selected. ----- Original Message ----- From: "Larry Mears" <LarryMears at hotmail.com> To: "EUforum" <EUforum at topica.com> Sent: Tuesday, September 25, 2001 1:58 PM Subject: message_box and EU 2.3? > > Is there any way that message_box will display more than > one line of text?
