You should always write each parameter of MessageBox in a separate line. So it will be more clear to read in the code. Format your message text in code as you want to see on the screen.

Private Sub ShowMyMessage()
 MessageBox.Show("Are
 you sure you want to delete the team project """ + strProjectName
 + """?" + Environment.NewLine + Environment.NewLine + "Warning:
 Deleting a team project cannot be undone.", strProductName + "
 " + strVersion(), MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2)

Private Sub ShowMyMessage()
 MessageBox.Show( _
 "Are you sure you want to delete the team project """ + strProjectName + """?"
 _ + Environment.NewLine _ +
 Environment.NewLine _ +
 "Warning: Deleting a team project cannot be undone.", _
 strProductName + " " + strVersion(), _
 MessageBoxButtons.YesNo, _
 MessageBoxIcon.Warning, _
 MessageBoxDefaultButton.Button2)
End Sub
