disable tasbar

can anyone  tell how to disable tasbar in wince 6 ?

You have to remove from the registry the keys Launch50 and Depend50 of
LOCALMACHINE\init, you can do this by adding the following lines to
project.reg:

[HKEY_LOCAL_MACHINE\init]
"Launch50"=-
"Depend50"=-

I found that in C:\WinCE600\PUBLIC\WCESHELLFE\OAK\FILES\wceshellfe.reg
there is an entry for same registry key  -- taskman.exe  . Is it need to be
delete that key value to disable taskbar ?

no peter,
to disable the taskbar you have to "disable" (read: not execute)
explorer.exe

In the key Launch50 you usually find explorer.exe, which means that on
startup windows will execute explorer.exe, and is this program the one that
handles the taskbar.

Adding the above lines to platform.reg, you are telling platform builder to
remove (that is what the minus sign means here, remove) the values from the
registry that execute explorer.exe

I hope this helps you.

I will just add an advice : you must never modify a file in the
C:\WinCE600\PUBLIC tree. 
These files can be modified when you install QFE (Windows CE updates).
For example, if you modify the wceshellfe.reg file and a new version of
this file is in a QFE, when you install this QFE, the new version of the
file will replace the file you modified and you will lose your
modifications.
