I have a few questions I've run into in developing my first Windows
Application (Delphi 2.01):

QUESTION ONE:  CLIPBOARD - I have the clipboard working with my program.
The mainmenu and popup menu works fine.  The problem is with the Paste
Button on the Toolbar.  It works fine with events generated within the
application, however, I do not know how to handle external clipboard
events.  For example if I have text on the clipboard (thus the paste button
is enabled) and I go to the Clipboard Viewer in windows and delete the
text. My Paste button does not disable, it is unaware of the change since
it occured external to the program.

QUESTION TWO:  FONTS - I have the Font and Size Combo Boxes on my toolbar.
I have seen documentation for the Font list using Screen.Fonts and
Printer.Fonts.  What I don't know is how to determine if the font is
TrueType and put the appropriate Glyph beside it (Like in WordPad).
Furthermore each font seems to have only certain valid size attributes.  I
don't know how to determine the valid sizes to generate the Size list.

QUESTION THREE:  ICON - I have an icon associated with the application for
use in Explorer etc.  I would like, however, to change the icon depending
on the type of file opened.  This is apparently accomplished by assigning
Application.Icon during Runtime.  The problem is I don't know how to get
the .ico files for the different associations to compile into the
executable.  The LoadFromFile method keeps it separate so requires the .ico
files to be in the same directroy at runtime.  I have tried the Image List
component but I don't seem to be able to get it to display properly.

This is first and foremost a learning experience for me.  Thus I am not
interested in third party components unless they have free source code as I
will not learn anything linking to pre-compiled code.  Furthermore any
pointers to other FREE Delphi References would be greatly appreciated.

Thanks in advance for any help.

I don't think there's a message driven way of doing this.  There is
a WM_DESTROYCLIPBOARD message, but it is only sent to the clipboard
owner, so you would only receive it when your own application modified
the clipboard.  As a last result, you could create a timer to check
the clipboard periodically.

I not sure if there is a Delphi function to do this, but you do this
using the EnumFontFamilies Win API call.  Look it up in the online
help.  Make sure to use the export directive with the callback function.

You could use the Image Editor that comes with Delphi to make a .RES
file containing the icons, giving them appropriate names within the
file, and then do something like this (using a Win API call)
Application.Icon.Handle := LoadIcon (HInstance, 'ICONNAME');
When done with the icon, call DestroyIcon (Application.Icon.Handle);
to free the memory it occupies.  You probably want to immediately
load another icon, unless the application is closing.

If you have difficulties implementing any of this, feel free to e-mail
me for assistance.

Good Luck!
