>You can have a look too at TRegDataType type, it seems there is nothing special for DWord. I got the list of functions you mentioned in Lazarus.. Here are all the ones that can read: function ReadCurrency(const Name: UnicodeString): Currency; function ReadCurrency(const Name: String): Currency; function ReadBinaryData(const Name: UnicodeString; var Buffer; BufSize: Integer): Integer; function ReadBinaryData(const Name: String; var Buffer; BufSize: Integer): Integer; function ReadBool(const Name: UnicodeString): Boolean; function ReadBool(const Name: String): Boolean; function ReadDate(const Name: UnicodeString): TDateTime; function ReadDate(const Name: String): TDateTime; function ReadDateTime(const Name: UnicodeString): TDateTime; function ReadDateTime(const Name: String): TDateTime; function ReadFloat(const Name: UnicodeString): Double; function ReadFloat(const Name: String): Double; function ReadInteger(const Name: UnicodeString): Integer; function ReadInteger(const Name: String): Integer; function ReadInt64(const Name: UnicodeString): Int64; function ReadInt64(const Name: String): Int64; function ReadString(const Name: UnicodeString): UnicodeString; function ReadString(const Name: String): string; procedure ReadStringList(const Name: UnicodeString; AList: TStrings; ForceUtf8: Boolean=False); procedure ReadStringList(const Name: String; AList: TStrings); function ReadStringArray(const Name: UnicodeString): TUnicodeStringArray; function ReadStringArray(const Name: String): TStringArray; function ReadTime(const Name: UnicodeString): TDateTime; function ReadTime(const Name: String): TDateTime; as far as I can see I need to use something like ReadBinaryData ??? does anyone have an example on how to do that? It looks like it's wanting a buffer of some sort. or can I just pass it my Dword variable somehow? It seems over complicated I still find it strange there is no ReadDword and ReadQword when those two are an entire third of possible registry entries.. If you go to RegEdit, there are only 6 kinds of registry entries: String Value Binary Value DWord Qword Multi-String Value Expandable String Value Maybe all these other ones like Float and Int64 are for other versions of windows?? As far as I can see it's impossible to define a float in the windows registry, with windows 10 professional 64 bit anyway. Are there other kinds of 'Registries' that all these functions would be useful for other than THE Registry (referring to the windows registry)? Am I missing something? Does Linux have a registry or something? I thought it was a windows thing. Why aren't there easy ways to read and write Dwords and Qwords when there are so many of them in the windows registry? Is all this for something other than the windows registry? The fact that the functions do not match what is possible with the windows registry is making me think I have the wrong thing all together. Are there functions to use the windows registry in the Windows unit? James
