Abstract:
Migration rule helper DLL
This source file implements helper functions needed to migrate the
system applications. Inside usermig.inf are rules that call this
DLL to do various data conversions. Two examples of these are
conversion of the accessibility cpl and desktop scheme conversions.

// To simplify things, you can write a reg val function when you only need
// to translate registry value settings. Depending on the pattern stored
// in usermig.inf or wkstamig.inf, your reg val function will be called for
// a single value, all values of a key, or all values of all keys and
// subkeys. You will *not* be called for the key or subkey itself.
//
// The text comment describes which values are expected by the reg val
// function.

// "key values" HKR\Foo\Bar Routine processes the values of a single key
// "key tree values" HKR\Foo\Bar\* Routine processes all values including subkeys
// "value" HKR\Foo\[Bar] Routine processes one value

this string is the same as SrcObjectStr. Registry key
mapping can influence the destination.
User - Specifies the user name (for the value function's use)

Routine Description:
RuleHlpr_ConvertAppPaths determines if a specific EXE referenced by an App
Paths entry (in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion) has been
moved or deleted.
If the EXE has been moved, the default value is updated to point to the
potentially new directory.
If the EXE has been deleted, the subkey is suppressed from being copied.
This function gets called by the usermig.inf/wkstamig.inf parser, not by
CopyObject. It gets called only once, and it is responsible for transferring
the entire key specified by SrcObjectStr to the key specified by DestObjectStr.
Arguments:
SrcObjectStr - Specifies Win9x registry key being enumerated (copy source)
DestObjectStr - Specifies WinNT registry key (copy destination)
User - Specifies the current user name (or NULL for default)
Data - Specifies caller-supplied data (see table in rulehlpr.c)
Return Value:

TRUE to continue procesing
FALSE and last error == ERROR_SUCCESS to continue on to the next rule
FALSE and last error != ERROR_SUCCESS if a fatal error occurred

Routine Description:
This routine uses the RuleHlpr_ConvertRegVal simplification routine. See
rulehlpr.c for details. The simplification routine does almost all the work
for us; all we need to do is update the value.
ValFn_AntiAlias checks if ShellState has bogus data. This usually happens when you have
fresh installed Win98 and you never switched ActiveDesktop on and off. If bogus data is
found, we writes some valid data so that the state of Active Desktop is preserved during
migration
Return Value:
Tri-state:
TRUE to allow merge code to continue processing (it writes the value)
FALSE and last error == ERROR_SUCCESS to continue, but skip the write
FALSE and last error != ERROR_SUCCESS if an error occurred
