推荐答案

一个消息框返回用户选择的值.
试试

A message box returns the value that the user has chosen.
Try

if (MsgBox("Are You sure you want to delete", MsgBoxStyle.YesNo, "Are You Sure")==DialogResult.Yes Then
            //Delete code here
            MsgBox("deleted succesfully")
            clear()
            AutoGenerate()
            fill()
EndIf
