I'm trying to read HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run with OpenKeyReadOnly
, and GetValueNames
, but it's returning values from HKLM\\SOFTWARE\\ \\Microsoft\\Windows\\CurrentVersion\\Run instead. \\Microsoft\\Windows\\CurrentVersion\\Run返回值。
How can I read the 64-bit values instead of from a redirect to the 32-bit key?
The program was run as an administrative account. I also tried RegOpenKeyEx
and RegEnumValue
.
I'm using Delphi 2010.
you must use the KEY_WOW64_64KEY
value when open the Registry with the TRegistry
class.
from MSDN :
KEY_WOW64_64KEY Indicates that an application on 64-bit Windows should operate on the 64-bit registry view. This flag is ignored by 32-bit Windows.
This flag must be combined using the OR operator with the other flags in this table that either query or access registry values.
try this sample app.
{$APPTYPE CONSOLE}
uses
Windows,
Classes,
registry,
SysUtils;
procedure ReadRegistry;
var
Registry: TRegistry;
List : TStrings;
begin
Registry := TRegistry.Create(KEY_WRITE OR KEY_WOW64_64KEY);
//Registry := TRegistry.Create(KEY_READ OR KEY_WOW64_64KEY);
List := TStringList.Create;
try
Registry.RootKey := HKEY_LOCAL_MACHINE;
if Registry.OpenKeyReadOnly('\SOFTWARE\Microsoft\Windows\CurrentVersion\Run') then
begin
Registry.GetValueNames(List);
Writeln(List.Text);
end;
Registry.CloseKey;
finally
Registry.Free;
List.Free;
end;
end;
begin
try
ReadRegistry();
except
on E:Exception do
Writeln(E.Classname, ': ', E.Message);
end;
Readln;
end.
