像QQ那样，任务栏可以显示多个图标，如何实现

Delphi(Pascal) code

procedure TfrmSubChat.CreateParams(var Params: TCreateParams);begin  inherited CreateParams(Params);  //Params.ExStyle := Params.ExStyle or WS_Ex_AppWindow or WS_EX_CLIENTEDGE;  //Params.ExStyle := Params.ExStyle or WS_Ex_AppWindow;    //最上层WS_EX_TOOLWINDOW,WS_EX_TOPMOST  //Params.WndParent := GetDesktopWindow;  //params.WndParent := 0;  //SetWindowLong(Handle,GWL_EXSTYLE,(GetWindowLong(Handle,GWL_EXSTYLE) or WS_EX_APPWINDOW));   //设父属性，0是桌面end;procedure TfrmSubChat.FormCreate(Sender: TObject);begin  //SetWindowLong(Handle, GWL_HWNDPARENT, Application.MainForm.Handle);end;

这些都试过了，效果很不理想，要么是主窗口时不时跳到前面，要么是在子窗口上打开保存|打开对话框有问题，跳后面去了

真复杂。TRAYICON能做出来吗？

任务栏很多个图标? 不会是聊天窗口吧？

我说个办法，把窗体封装在dll中
主程序调用时创建它即是了，都是独立的窗体，任务栏会显示图标
至于如何通信。这是另外的问题

[解决办法]
是不是得考虑 具体系统环境 啊，，，XP,,2000,,,WIN7,,,估计不一样吧，，
