How do I unload a Smartphone app via the Compact Framework

Hello all,
In order to programmatically uninstall an app via the Compact Framework,
one just calls "\Windows\unload.exe", "appname.exe" on the Pocket PC. The
Smartphone doesn't include unload.exe or even wceload.exe anywhere on the
device. So how does one accomplish this task? Is there some other exe to
call that accomplishes the same function?

Thanks,

On Smartphone you do it via DMProcessConfigXML (or RapiConfig fropm the
desktop) by feeding it something like this:

<wap-provisioningdoc>
<characteristic type="UnInstall">
<characteristic type="Some Application">
<parm name="uninstall" value="1"/>
</characteristic>
</characteristic>
</wap-provisioningdoc>

Alex, do you have any clue as to what the P/Invoke looks like to call
DMProcessConfigXML?

Thanks,
Rob

[DllImport("coredll")]
static extern int DMProcessConfigXML(
string pszWXMLin,
int dwFlags,
out IntPtr ppszwXMLout
);

The dwFlags value should be set to CFGFLAG_PROCESS = 1

The minor problem with the call is that the returned string buffer is
supposed to be deallocated via delete[] ppszwXMLOut, which is of course not
possible to do in managed code. Instead of writing a wrapper, I believe you
can simply P/Invoke LocalFree as that's what the delete does in CRT (and I
just looked it up - indeed all delete does is calls into LocalFree)

Thanks Alex, I'll give it a shot.
