如何在程序的开始菜单中创建菜单?

这可能是一个简单的问题,但我甚至不确定要搜索的术语,所以我不得不问。如果将程序固定到开始菜单,我希望我的程序有一个菜单。我附上了一个截图,其中windows powershell说明了这个功能,并提供了一个任务列表。

其他程序有时使用它来列出最近打开的文件等。我确信这是标准的,在某个地方有一个教程,有人会指点我,或解释如何做到这一点?我希望使用什么语言并不重要,但我精通Delphi,C ++和C#。

您必须使用ICustomDestinationList.AddUserTasks方法,该方法是Windows 7中引入的Taskbar Extensions的一部分。

更新

尝试此示例控制台应用,运行代码并将应用的快捷方式移至开始菜单。 (这只是一个示例代码段,所以请记住添加对所有返回HResult值的方法的结果的检查)

program ProjectTasks;

{$APPTYPE CONSOLE}

{$R *.res}

uses
  SysUtils,
  ActiveX,
  windows,
  ComObj,
  ShlObj,
  PropSys,
  ObjectArray;

const
  PKEY_TITLE : TPropertyKey = ( fmtID : '{F29F85E0-4FF9-1068-AB91-08002B27B3D9}'; pID : 2);

procedure CreateTaskList;
var
  LCustomDestinationList : ICustomDestinationList;
  pcMaxSlots : Cardinal;
  ppv : IObjectArray;
  poa : IObjectCollection;
  LTask : IShellLink;
  LPropertyStore : IPropertyStore;
  LTitle : TPropVariant;
  LTaskBarList : ITaskBarList;
  LTaskBarList3 : ITaskBarList3;
  hr : HRESULT;
begin
    LTaskBarList := CreateComObject(CLSID_TaskBarList) as ITaskBarList;
    hr := LTaskBarList.QueryInterface(IID_ITaskBarList3, LTaskBarList3);
    if hr <> S_OK then exit;


    LCustomDestinationList := CreateComObject(CLSID_DestinationList) as ICustomDestinationList;
    LCustomDestinationList.BeginList(pcMaxSlots, IID_IObjectArray, ppv);
    poa := CreateComObject(CLSID_EnumerableObjectCollection) as IObjectCollection;


    LTask := CreateComObject(CLSID_ShellLink) as IShellLink;
    LTask.SetPath(pChar(ParamStr(0))); //set the  path to the exe
    LTask.SetDescription('This is a description sample');
    LTask.SetArguments(PChar('Bar'));
    LTask.SetIconLocation(PChar('Shell32.dll'),1);
    LPropertyStore := LTask as IPropertyStore;
    LTitle.vt := VT_LPWSTR;
    LTitle.pwszVal := PChar('This is the Task 1');
    LPropertyStore.SetValue(PKEY_Title,LTitle);
    LPropertyStore.Commit;
    poa.AddObject(LTask);

    LTask := CreateComObject(CLSID_ShellLink) as IShellLink;
    LTask.SetPath(PChar(ParamStr(0))); //set the  path to the exe
    LTask.SetDescription('This is a description sample');
    LTask.SetArguments(PChar('Foo'));
    LTask.SetIconLocation(pChar('Shell32.dll'),1);
    LPropertyStore := LTask as IPropertyStore;
    LTitle.vt := VT_LPWSTR;
    LTitle.pwszVal := pChar('This is the Task 2');
    LPropertyStore.SetValue(PKEY_Title,LTitle);
    LPropertyStore.Commit;
    poa.AddObject(LTask);


    LCustomDestinationList.AddUserTasks(poa as IObjectArray);
    LCustomDestinationList.CommitList;
end;

begin
 try
    CoInitialize(nil);
    try
       CreateTaskList;
    finally
      CoUninitialize;
    end;
 except
    on E:EOleException do
        Writeln(Format('EOleException %s %x', [E.Message,E.ErrorCode]));
    on E:Exception do
        Writeln(E.Classname, ':', E.Message);
 end;
 Writeln('Press Enter to exit');
 Readln;
end.
