Getting the UpgradeCode (or any property) from an MSI file is fairly
straightforward with code. I found my old generic C++ function:
UINT GetProperty (MSIHANDLE dbHand, LPCTSTR propname, LPTSTR strVal)
{
PMSIHANDLE viewH = NULL;
WCHAR qry [100] = {0};
StringCchCat (qry, 100, L"Select `Value` from `Property` where
`Property`='" );
StringCchCat (qry, 100, propname);
StringCchCat (qry, 100, L"'");
UINT res = MsiDatabaseOpenView (dbHand, qry, &viewH);
if (ERROR_SUCCESS!=res)
return res;
res = MsiViewExecute (viewH, 0);
if (ERROR_SUCCESS!=res)
{
MsiCloseHandle (viewH);
return res;
}
PMSIHANDLE recH=NULL;
res = MsiViewFetch (viewH, &recH);
if (ERROR_SUCCESS!=res)
{
MsiCloseHandle (viewH);
return res;
}
WCHAR buff [50] = {0};
DWORD dwlen = 50;
res = MsiRecordGetString (recH, 1, buff, &dwlen);
if (ERROR_SUCCESS!=res)
{
MsiCloseHandle (viewH);
MsiCloseHandle (recH);
return res;
}
StringCchCopy (strVal, dwlen+1, buff);
MsiViewClose (viewH);
MsiCloseHandle (recH);
return (ERROR_SUCCESS);
}
