如何在运行时更新任务栏图标的工具提示文本?

大家好

我被困在某一点.我已经制作了一个应用程序，其中我要在其图标的工具提示中以百分比显示任务的进度状态.我该怎么办?

以下是Icon的创建过程:

Hi All

I am stuck at one point. I have made an application in which I want to show the progress status of a task in percentage in the tool-tip of its icon. How can I do this?

Below is the creation procedure of Icon:

HINSTANCE hInstance = AfxGetResourceHandle();
CString strToolTipText = _T("This is a Tray Icon - Right click on me!");
// Create the tray icon
if (!TrayIcon.Create(hInstance,
     theApp.GetMainWnd()->GetSafeHwnd(), // Parent window
     WM_ICON_NOTIFY,                  // Icon notify message to use
     strToolTipText,  // tooltip
     ::LoadIcon(hInstance, (LPCTSTR)IDR_MAINFRAME),
     NULL)) 
return FALSE;

我想更新"strToolTipText"运行时.请为此建议我一些.我在Application类中完成所有这些操作.图片中没有对话框.

在此先感谢

I want to update ''strToolTipText'' runtime. Please suggest me something for this. I do this all in Application class. No dialog is in picture.

Thanks in advance
