Q: I don't want users of my system to have any chance of accessing the Windows CE desktop. How can I do this?
You can use the following registry key on most ADS products to suppress the CE desktop by disabling the shell :
; Most ADS Boards
[HKEY_LOCAL_MACHINE\Platform]
"LaunchCEShell"=dword:0 ; 1=show desktop, 0=suppress desktop
; Sphere
[HKEY_LOCAL_MACHINE\Software\ADS\Behavior]
"LaunchExplorerAtStartup"=dword:0
|
The key above is phasing in to CE builds in early 2006. The following deprecated keys are used in CE builds created before this period. The keys include the platform name, and apply to all ADS products (BitsyX, AGX, VGX, GCX and others). Select the product key that matches your platform:
[HKEY_LOCAL_MACHINE\Platform\GCPlus]
[HKEY_LOCAL_MACHINE\Platform\GMaster]
[HKEY_LOCAL_MACHINE\Platform\Bitsy]
[HKEY_LOCAL_MACHINE\Platform\BitsyPlus]
"LaunchCEShell"=dword:0 ; 1=show desktop, 0=suppress desktop |
When you do this, you will get no CE desktop after boot. To run automatically your application must be in one of the following locations:- "flashfx disk\startup\" folder (most common)
- "storage card\startup\" (PCMCIA) folder
- loaded into onboard flash as "adsload.exe"
To display/use the CE desktop when it is suppressed, you can do one of the following:- Change the above key in the ADSLOAD.REG file to show the desktop
- Launch Explorer programmatically (see topic 1176 for discussion):
CreateProcess(_T("explorer.exe"), NULL, NULL, NULL, FALSE, 0, NULL, NULL, NULL, NULL);
- Put the Run_Explorer.exe application in the startup folder of your PCMCIA ATA card
This will display the CE desktop and override any executable files installed in the FlashFX disk
Note: Suppression of the desktop was added beginning with CE builds built November 2000 and later. The launch key was updated beginning in early 2006.
