ShowBalloonTip stops working in windows 10

Question

The CEdit MFC class has a ShowBalloonTip function.
It is triggered, for example, with the ES_NUMBER flag, showing a warning.
After installing updates or some applications, I don't know for sure, this function stops working. BalloonTip stops appearing.
I have already reinstalled the system twice because of this.
Please tell me how to fix this glitch without reinstalling windows?

Answer 1

Cedit::ShowBalloonTip worked for me - Win 10 21H1 and VS2019 using an MFC dialog application created by the MFC App template.

void CEditBalloonDlg::OnChangeEdit2()  
{  
    // TODO:  If this is a RICHEDIT control, the control will not  
    // send this notification unless you override the CDialogEx::OnInitDialog()  
    // function and call CRichEditCtrl().SetEventMask()  
    // with the ENM_CHANGE flag ORed into the mask.  
  
    // TODO:  Add your control notification handler code here  
    m_Edit2.ShowBalloonTip(_T("Change Tip"), _T("Edit control changed"), TTI_INFO);  
}  
  
  
void CEditBalloonDlg::OnSetfocusEdit1()  
{  
    // TODO: Add your control notification handler code here  
    m_Edit1.ShowBalloonTip(_T("Focus Tip"), _T("Edit control got Focus"), TTI_INFO_LARGE);  
}

Hi @Вадим Подгорный ,

In win10, I suggest you try this method: go to Settings > System > Notifications & actions, and turn on "Get notifications from apps and other senders".

Best regards,

Answer 3

After thinking about it logically, I assumed that many people should have had such a problem already.
And I found a solution on the Internet, where one smart person suggested it, thanks to him.

1.Open regedit.exe

2.Navigate to HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced

3.Set (or add) EnableBalloonTips (as REG_DWORD) and set value to 1

4.Reboot

The application that I am writing at the moment actively uses hints.
It's a pity that Microsoft has complicated this task for me.
You will have to write an additional module to control the registry, ask the user to restart the computer....
