Title: File context menu entry for Explorer
Question: It is difficult to add an context entry to explorer, which pops up when user click with the mouse on a file. Usually this is done with com programming.
A simple way to enter a single entry can be provided via registry.
Answer:
uses registry;
procedure AddEntryToExplMenu(Adding:boolean);
const
DirExtensionKey = 'Directory\shell\encrypt';
FileExtensionKey = '*\shell\';
SubKey = '\command';
ContextName= 'Enter Context Name here';
IMPLEMENTATION
{$R *.dfm}
PROCEDURE TfmOptions.AddEntryToExplMenu(Adding:boolean);
var
reg: TRegistry;
begin
try
reg := TRegistry.Create;
except
Exit;
end;
if Adding then
with reg do
begin
RootKey := HKEY_CLASSES_ROOT;
OpenKey(FileExtensionKey, Adding);
WriteString('', ContextName);
CloseKey;
OpenKey(FileExtensionKey + ContextName+SubKey, Adding);
WriteString('', ParamStr(0) + ' "%1"');
CloseKey;
end
else
with reg do
begin
RootKey := HKEY_CLASSES_ROOT;
DeleteKey(FileExtensionKey + ContextName);
CloseKey;
end;
reg.Free;
END;
