The Incredible Scrolling Credits Box
------------------------------------
Thank you for using the incredible scrolling credits box component. This is
the first component I have written, and I had a lot of fun creating it and
learning about how cool component writting can be. I have tested this
component on a number of machines, and it appears to be quite stable. There
is only one minor irritation that you may experience while using this
component. The credits box hooks one of the system timers, and it fires every
50 milliseconds. As a result, if you have the Started property set to True at
design time, the credits box will come alive and you will see your text
scrolling smoothly upward, but when accessing properties or other objects that
have a drop down list box, you will be required to press the mouse button
continually to scroll through the options. I suggest that you set Started to
True during design time only to see how your credits will appear, as this will
minimize any inconvienience this little quirck may cause.
You should find the following files after unzipping this archive:
-----------------------------------------------------------------
Readthis.txt - The file you are reading now
Order.frm - The registration order form. This is just a regular
text file. Mail this form to me when you register the
component.
Credits.dcu - The Delphi Compiled Unit. This is the actual component.
Credits.dcr - The Delphi Component Palette icon. This is the picture
you should see on the Samples page when you install the
credits box.
Credhelp.hlp - The credits box help file. This is a simple help file
that explains the component specific properties.
Credhelp.kwf - The credits box keyword file. This file is used to
connect the component to Delphi's help system, so you
can press 'F1' when a property is highlighted in the
property inspector and jump to the appropriate page in
the help file.
To install the component, follow these steps:
---------------------------------------------
1) Put the Credits.dcu, Credits.dcr, Credhelp.hlp, and Credhelp.kwf in
the directory where you want to store them.
2) Select Options|Install Components from the Delphi menu. Make sure
that the directory where you saved the above files appears in the
search path box.
3) Click the Add button, and then click the Browse button. Change to
the directory where you stored the above files, and select the
Credits.dcu file.
4) Click the OK button. This should drop you back to the first window
labeled 'Install Components.' Click the OK button, and Delphi will
rebuild the component library. After it is finished, you will find
the credits box component on the Samples page of the component
palette.
To install the help and keyword file, follow these steps:
---------------------------------------------------------
1) Click on the Helpinst icon in the Delphi group in the Program
Manager.
2) Select File|Open from the menu. Change directories so you are in
the C:\Delphi\Bin directory, and select the Delphi.hdx file. Click
the OK button.
3) Select Keywords|Add Keyword File from the menu. Change directories
so you are in the directory where you stored the files in the
zipped archive. Select the Credhelp.kwf file, and click the OK
button.
4) Select File|Save from the menu. This will recompile the Delphi.hdx
file. You can then close the Helpinst program. You will now be
able to jump to the help file for the credits box component by
selecting the appropriate property and hitting 'F1.'
Note: If Windows has problems opening the help file, you may want to move the
Credhelp.hlp file into the C:\Delphi\Bin directory.
