如何把程序釘到Windows7任務欄

在CSDN論壇看到有網友提問如何把程序釘到Windows7的任務欄，ccrun(妖哥)對這個問題很感興趣，因而google了一下，沒有找到相關的API資料，可是在國外的一個站點看到用FolderItemVerb對象來實現的方法，關於具體的資料，能夠查閱MSDN:

在Delphi中實現的代碼以下。編譯環境：Delphi7和XE2，測試操做系統爲中文和英文Windows7

uses ComObj;

procedure CrnPinAppToWin7Taskbar(strPath, strApp: string);
var
  vShell, vFolder, vFolderItem, vItemVerbs: Variant;
  vPath, vApp: Variant;
  i: Integer;
  str: String;
  h: HINST;
  szPinName: array[0..255] of Char;
begin
  vShell := CreateOleObject('Shell.Application');
  vPath := strPath;
  vFolder := vShell.NameSpace(vPath);
  vApp := strApp;
  vFolderItem := vFolder.ParseName(vApp);
  vItemVerbs := vFolderItem.Verbs;

  h := LoadLibrary('Shell32.dll');
  LoadString(h, 5386, szPinName, 256);
  FreeLibrary(h);

  for i := 1 to vItemVerbs.Count do
  begin
    str := vItemVerbs.Item(i).Name;

    if SameText(str, szPinName) then
    begin
      // 63 63 72 75 6E 2E 63 6F 6D
      vItemVerbs.Item(i).DoIt;
    end;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  CrnPinAppToWin7Taskbar('C:\windows', 'regedit.exe');
end;

在C++Builder中的實現代碼以下。編譯環境：C++Builder6和XE2，測試操做系統：中文和英文Windows7

#include <comobj.hpp>

void __fastcall CrnPinAppToWin7Taskbar(String strPath, String strApp)
{
    Variant vShell = CreateOleObject("Shell.Application");
    Variant vFolder = vShell.OleFunction("NameSpace", WideString(strPath));
    Variant vFolderItem = vFolder.OleFunction("ParseName", WideString(strApp));
    Variant vItemVerbs = vFolderItem.OleFunction("Verbs");

    // 獲取Pin to Taskbar的Verb字符串, 感謝titilima
    HINSTANCE hInst = ::LoadLibrary("Shell32.dll");

    TCHAR szPinName[256] = { 0 };
    ::LoadString(hInst, 5386, szPinName, 256);

    ::FreeLibrary(hInst);

    String str;

    int nCount = vItemVerbs.OlePropertyGet("Count");
    for (int i = 0; i < nCount; i++)
    {
        str = vItemVerbs.OleFunction("Item", i).OlePropertyGet("Name");

        if (SameText(str, szPinName))
        {
            // 63 63 72 75 6E 2E 63 6F 6D
            vItemVerbs.OleFunction("Item", i).OleFunction("DoIt");
        }
    }
}

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    CrnPinAppToWin7Taskbar("C:\\windows\\", "notepad.exe");
}

另外，感謝titilima大牛，針對.lnk文件釘到Win7任務欄，有更簡便的方法：

C++代碼：

::ShellExecute(NULL, TEXT("TaskbarPin"), TEXT("E:\\Temp\\Notepad.lnk"), NULL, NULL, SW_SHOW);

Delphi代碼：

ShellExecute(nil, 'TaskbarPin', 'E:\Temp\Notepad.lnk'), nil, nil, SW_SHOW);
