Routine Description:
This routine computes the resource string identified by the resource
identifier 'MsgId'. In addition to the 'printf' format strings
supported, 'QueryResourceString' supports :
1. '%W' - Expects a pointer to a WSTRING.
Arguments:
ResourceString - Returns the resource string.
MsgId - Supplies the message id of the resource string.
Format - Supplies a 'printf' style format descriptor for the
arguments to the resource string.
... - Supplies the arguments to the resource string.
Return Value:
FALSE - Failure.
TRUE - Success.
