代码截图
一、在模块中作如下申明：
Declare Function SendMessage Lib "user32" Alias "SendMessageA" ( _
ByVal hwnd As IntPtr, _
ByVal wMsg As Integer, _
ByVal wParam As Integer, _
ByVal lParam As Integer) _
As Boolean
Declare Function ReleaseCapture Lib "user32" Alias "ReleaseCapture" () As Boolean
Public Const WM_SYSCOMMAND = &H112
Public Const SC_MOVE = &HF010&
Public Const HTCAPTION = 2
二、在窗体的MousMove事件中添加代码：
Private Sub frmFlash_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
ReleaseCapture()
SendMessage(Me.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0)
End Sub
