Overwrite exe silently

I'm writing the auto update part of my application.

Step 1 is downloading the application to the PDA, this works fine. The next
part is executing the cab file, this all works fine but the user does need to
interact to say "Yes" to the overwriting of the exe file.

My question is, is there anyway for this to be done automatically ?

I notice Visual Studio doesn't prompt you to overwrite the file when you run
it from the development environment, how does it do that ?

Many thanks
Rob

To suppress UI try to execute 'wceload' in this manner:

wceload.exe /noui /noaskdest yourcab.cab

Thanks for the reply.

Currently, i'm downloading the file, and then on startup i'm running the cab.

So... as you suggest, i'm changing my code to something like this:

success = SHCreateShortcut(@"\WINDOWS\Startup\SAMSLoad.lnk", @"wceload.exe
/noui /noaskdest \Program Files\SAMS PDA\download.cab");

However, no error but doesn't seem to do anything.

Does that look right?

Thanks again.

In fact, i've just noticed i don't seem to have wceload.exe

I'm running Qtek2020 with PocketPC 2003

hmm... any ideas?

Include quotes around the path:

SHCreateShortcut(@"\WINDOWS\Startup\SAMSLoad.lnk", @"wceload.exe
/noui /noaskdest ""\Program Files\SAMS PDA\download.cab""");

Ah, that works nicely. Although there is just one more thing, it still comes
up with the message "SAMS PDA is already installed, re-install?"

Anyway to supress that as well?

Thanks Sergey

When wceload installing your cab it creates the key in
HKLM\SOFTWARE\Apps with the name 'SAMS PDA' (or something like this). In
your application you may try to delete this key by using
OpenNETCF.Win32.RegistryKey class:

It will make think the wceload that a cab have not been installed.

Ah, ok...sounds like it might work. The application name (under 'Remove
Programs) is 'SM SAMS PDA'.

I'm using the below code but it doesn't seem to be deleting it (still
prompting me to reinstall)

Registry.LocalMachine.DeleteSubKey(@"HKLM\SOFTWARE\SM SAMS PDA",false);

Does that look right?

many thanks for the help

No. "HKLM" is the lazy man's (me included!) way of typing
HKEY_LOCAL_MACHINE. By using Registry.LocalMachine, you already have that,
so it would be more like this:

Registry.LocalMachine.DeleteSubKey("SOFTWARE\\SM SAMS PDA",false);
