Ok,

You will need to derive your new component from TComponent:

Do the following from Delphi Main Menu:

File\New\Other

Double CLick on Component



Select TComponent as Ancestor Type

For Class Name, give it the name you want to give it, example: TMyComponent

Selectthe palette page you want it to reside on, or enter a new one

The point where you want the unit to be saved and give it a name

Example

C:\Program Files\Borland\Delphi7\Lib\MYCOMP.pas

Note: Do not name the file as the same name as component

Then Hit install, and add all your functions and procedures to it, and then compile.

as for adding a component image, you will need to create a  resource file using the image editor included
with Delphi, then in that resource file add a new Bitmap 24x24 (16 colors is what I use) name that
bitmap the same as the name of the new class, so if your new class is TMYCOMPONENT the bitmap would be
named TMYCOMPONENT as well then after you get done with that when you save the resource file itself name it the same as the component's .pas file except use a .dcr extenstion e.g.

If you component is contained in a unit named MyComp.pas you would save the resource file as MyComp.dcr, if this dcr files accessible during the compile then that will be the bitmap used to represent your component on the palette and when you drop it on forms.

is fav = favorite ?
What is a component ?
You can use 1 or more TEdits, TMemos or TLabels in the same project and every of them is independent and working as individually....
What about your fav functions (if fav = favorites) ? It is enough to be placed into a unit. Then this unit is declared into the uses clause of every other unit which calls one or more of favorite mwthods.
It is not necessary to be a components, you don't need more instances of it....

Russell LibbySoftware Engineer, Advisory Commented:
Regarding the component resource (which controls the component image in), you should use the Image Editor that comes with Delphi.

File | New | Component Resource
Resource | New | Bitmap
Height and width should be set to 24x24, 16 color
Rename this image to be that of the component (TWhatever)

Save the .dcr file with the same filename that the component unit is called.

So you should have

compsource.pas
compsource.dcr
