Uninstall_Init not called after codeUNINSTALL_INIT_CANCEL

TheMSsForum.com: The Microsoft Software Forum

I have a PocketPC logon replacement app developed in eVC++3 which is
installing and working fine.

However, when it is uninstalled it needs to check if it is still
active and prompts the user to disable it. i.e:

codeUNINSTALL_INIT Uninstall_Init(HWND hwndparent,LPCTSTR
pszinstalldir)
{
if (still active)
{
MessageBox(hwndparent, _T("Still active."), _T("App"), MB_OK);
return codeUNINSTALL_INIT_CANCEL;
}

// do clean up ...
}

This works fine the first time. But if you click the 'Remove' button
again in Remove Programs, it goes ahead and removes the whole app
anyway without calling the Uninstall_Init function again?

Is this by design or I am missing something?

Appreciate any help!

Thanks,


Colin

I think that Pocket PC application manager automaticly close all opened
windows when uninstall any programs. So after first run of unistall your
program is not running at second time.

Ilya,

Thanks, but surely it would still run the uninstall hooked functions,
Uninstall_Init and Uninstall_Exit? It just seems to skip past them and
remove the application anyway.

What if I wanted to do some clean up in those functions, how would
they get called?

Thanks again,


Colin
