.net - C# MessageBox To Front When App is Minimized To Tray

Question

I have some code that popups a message box:

MessageBox.Show(this,
                 "You have not inputted a username or password. Would you like to configure your settings now?",
                 "Settings Needed",
                 MessageBoxButtons.YesNo,
                 MessageBoxIcon.Question);

My problem is when this pops up my app is usually minimized to the tray. As a result the messagebox doesn't come to the front and it also doesnt appear along the start bar. The only way of seeing it is by alt-tabbing.

Here is the code that minimizes my app (the parent) to the tray:

if (FormWindowState.Minimized == WindowState)
{                
      Hide();                
}

There's an additional flag you can specify as an option to the standard Windows MessageBox function that isn't exposed in the WinForms wrapper.

What you're looking for is called MB_TOPMOST, which ensures that the message box is displayed as the top-most window over everything else on your desktop. Simply amend your code as shown below:

MessageBox.Show(this,
                "You have not inputted a username or password. Would you like to configure your settings now?",
                "Settings Needed",
                MessageBoxButtons.YesNo,
                MessageBoxIcon.Question,
                MessageBoxDefaultButton.Button1,  // specify "Yes" as the default
                (MessageBoxOptions)0x40000);      // specify MB_TOPMOST
