Народ подскажите как мне из своей программы отправить нажатие клавиши в другую прогу. Тоесть как будто я на клавиатуре нажал клавишу "A" но при етом другая прога которой предназначено ето нажатие может быть свернута в трей.
И как сделать тоже самое с программным кликом мышки?

А если не сложно то можно примерчик?
Для точности действий опищу что конкретно надо.
Есть прога №1 которая запущена и висит в трее, надо мне из своей проги №2 через каждые 3 минуты кидать в прогу №1 кажатие клавиши "А" и через каждые 5 минут нажатие кл. "B".
Самое противное что 1 раз в час надо съемулировать нажатие правой кнопки мыши и прогу №1.
Если кого не затруднит киньте решение вопроса желательно с примером.

Правда, это - немного старый вариант, но то, что ты просишь тут уже есть - см. процедуру RasCommand.

(*
SendKeys routine for 32-bit Delphi.

Written by Ken Henderson

Copyright (c) 1995 Ken Henderson

This unit includes two routines that simulate popular Visual Basic
routines: Sendkeys and AppActivate.  SendKeys takes a PChar
as its first parameter and a boolean as its second, like so:

SendKeys("KeyString", Wait);

where KeyString is a string of key names and modifiers that you want
to send to the current input focus and Wait is a boolean variable or value
that indicates whether SendKeys should wait for each key message to be
processed before proceeding.  See the table below for more information.

AppActivate also takes a PChar as its only parameter, like so:

AppActivate("WindowName");

where WindowName is the name of the window that you want to make the
current input focus.

SendKeys supports the Visual Basic SendKeys syntax, as documented below.

Supported modifiers:

+ = Shift
^ = Control
% = Alt

Surround sequences of characters or key names with parentheses in order to
modify them as a group.  For example, "+abc" shifts only "a", while "+(abc)" shifts
all three characters.

Supported special characters

~ = Enter
( = Begin modifier group (see above)
) = End modifier group (see above)
{ = Begin key name text (see below)
} = End key name text (see below)

Supported characters:

Any character that can be typed is supported.  Surround the modifier keys
listed above with braces in order to send as normal text.

Supported key names (surround these with braces):

BKSP, BS, BACKSPACE
BREAK
CAPSLOCK
CLEAR
DEL
DELETE
DOWN
END
ENTER
ESC
ESCAPE
F1
F2
F3
F4
F5
F6
F7
F8
F9
F10
F11
F12
F13
F14
F15
F16
HELP
HOME
INS
LEFT
NUMLOCK
PGDN
PGUP
PRTSC
RIGHT
SCROLLLOCK
TAB
UP

Follow the keyname with a space and a number to send the specified key a
given number of times (e.g., {left 6}).

This is used to set the current input focus to a given window using its
name.  This is especially useful for ensuring a window is active before
sending it input messages using the SendKeys function.  You can specify
a window"s name in its entirety, or only portion of it, beginning from
the left.
