在CSDN论坛看到有网友提问如何把程序钉到Windows7的任务栏,ccrun(妖哥)对这个问题很感兴趣,于是google了一下,没有找到相关的API资料,但是在国外的一个站点看到用FolderItemVerb对象来实现的方法,关于具体的资料,可以查阅MSDN: http://msdn.microsoft.com/en-us/library/windows/desktop/bb774172(v=vs.85).aspx
在Delphi中实现的代码如下。编译环境:Delphi7和XE2,测试操作系统为中文和英文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中的实现代码如下。编译环境:C++Builder6和XE2,测试操作系统: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"); // 获取Pin to Taskbar的Verb字符串, 感谢titilima HINSTANCE hInst = ::LoadLibrary(TEXT("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,感谢titilima大牛,针对.lnk文件钉到Win7任务栏,有更简便的方法:
C++代码:
::ShellExecute(NULL, TEXT("TaskbarPin"), TEXT("E:\Temp\Notepad.lnk"), NULL, NULL, SW_SHOW);
Delphi代码:
ShellExecute(nil, 'TaskbarPin', 'E:TempNotepad.lnk'), nil, nil, SW_SHOW);
