Shell_notifyicon& NOTIFYICONDATA [英] Shell_notifyicon & NOTIFYICONDATA

问题描述

我们正在尝试将Shell_NotifyIcon与NOTIFYICONDATA结构一起使用。在Window 10上，我们看到如果我们尝试显示气球通知区域以及Title ICON，ICON会在每次显示时复制到temp文件夹。有可能避免这种情况吗？我们有一些用例，因为我们不希望在显示通知时触发任何文件复制操作。



我们尝试的示例代码如下：

We are trying to use Shell_NotifyIcon along with NOTIFYICONDATA structure. On Window 10, We are seeing that if we try to display the balloon notification area along with Title ICON , the ICON gets copied to temp folder everytime it is displayed. It is possible to avoid this ? We have certain use case due to which we do not want any file copy operation triggered while displaying the notifications.

Sample code we tried is as follows:

void CTrayIconTestDlg::AddIconToSysTray()
{
	HICON	m_hIconInfo = NULL;//(HICON)::LoadImage(), MAKEINTRESOURCE(IDI_ICON_INFO), IMAGE_ICON, 16, 16, LR_DEFAULTCOLOR | LR_LOADTRANSPARENT);

	// TODO: Add your control notification handler code here
	NOTIFYICONDATA NID;

	memset(&NID, 0, sizeof(NID));

	//on main function:
	NID.cbSize = sizeof(NID);
	NID.hIcon = this->m_hIcon;
	
	NID.hWnd = this->m_hWnd;
	NID.uID = WM_USER + 2;
	StrCpyW(NID.szTip, L"System Tray Icon: Hello World");
	//in a timer:
	
	NID.uFlags = NID.uFlags | NIF_ICON | NIF_TIP ;
	Shell_NotifyIcon(NIM_ADD, &NID);

	//CDialogEx::OnOK();
}

void CTrayIconTestDlg::DisplayNotification()
{
	// TODO: Add your control notification handler code here
	NOTIFYICONDATA NID;
	memset(&NID, 0, sizeof(NID));
	//on main function:
	NID.cbSize = sizeof(NID);
	NID.hIcon = this->m_hIcon;
	
	NID.hWnd = this->m_hWnd;
	NID.uID = WM_USER + 2;
	StrCpyW(NID.szTip, L"System Tray Icon: Hello World");
	//in a timer:
	
	NID.uFlags = NID.uFlags | NIF_ICON | NIF_INFO | NIF_TIP ;

	StrCpyW(NID.szInfoTitle, L"This is balloon title");
	StrCpyW(NID.szInfo, L"This is balloon Information detailed");

	NID.uTimeout = 5000;
	NID.dwInfoFlags = NID.dwInfoFlags | NIIF_INFO;
	
	//NID.dwInfoFlags = NID.dwInfoFlags | NIIF_USER;
	//NID.hBalloonIcon = this->m_hIcon;

	BOOL res = Shell_NotifyIcon(NIM_MODIFY, &NID);
	if( res == FALSE )
		MessageBoxA(NULL, "False", "", MB_OK);
}

我的尝试：



1）MSDN文档

2）在Windows 7上尝试相同的代码，它不会将ICON复制到临时文件夹

What I have tried:

1) MSDN documentation
2) Tried same code on Windows 7, it does not copy the ICON to temp folder

推荐答案

在Windows 10上无法避免这种情况。如果您使用其中一种产品接受错误报告，可能需要提交错误信息：
