Imports System.Runtime.InteropServices

Sub Main()

Dim instance As Process = RunningInstance()

If instance IsNot Nothing Then

ShowWindowAsync(instance.MainWindowHandle, 3) '调用api函数，正常显示窗口

Return

End If

Dim F1 As New Form1

Application.Run(F1) '显示窗体

End Sub

DllImport("User32.dll")

Public Function ShowWindowAsync(ByVal hWnd As System.IntPtr, ByVal cmdShow As Integer) As Boolean

End Function

Private Function RunningInstance() As Process '返回进程中已经打开的程序

Dim current As Process = Process.GetCurrentProcess()

Dim processes As Process() = Process.GetProcessesByName(current.ProcessName)

For Each process As Process In processes

If process.Id current.Id Then

If process.MainModule.FileName = current.MainModule.FileName Then

Return process

Return Nothing
