把屏幕的上内容 picture中显示出来 Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long Private Declare Function StretchBlt Lib "gdi32" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal nSrcWidth As Long, ByVal nSrcHeight As Long, ByVal dwRop As Long) As Long Private Sub Command1_Click() Dim wScreen As Long Dim hScreen As Long Dim w As Long Dim h As Long Picture1.Cls wScreen = Screen.Width \ Screen.TwipsPerPixelX hScreen = Screen.Height \ Screen.TwipsPerPixelY Picture1.ScaleMode = vbPixels w = Picture1.ScaleWidth h = Picture1.ScaleHeight hdcScreen = GetDC(0) r = StretchBlt(Picture1.hdc, 0, 0, w, h, hdcScreen, 0, 0, wScreen, hScreen, vbSrcCopy) End Sub
抓取屏幕
保存(也可以不用)

接收数据
显示采用Socket
Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function StretchBlt Lib "gdi32" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal nSrcWidth As Long, ByVal nSrcHeight As Long, ByVal dwRop As Long) As Long
Private Sub Command1_Click()
Dim wScreen As Long
Dim hScreen As Long
Dim w As Long
Dim h As Long
Picture1.Cls
wScreen = Screen.Width \ Screen.TwipsPerPixelX
hScreen = Screen.Height \ Screen.TwipsPerPixelY
Picture1.ScaleMode = vbPixels
w = Picture1.ScaleWidth
h = Picture1.ScaleHeight
hdcScreen = GetDC(0)
r = StretchBlt(Picture1.hdc, 0, 0, w, h, hdcScreen, 0, 0, wScreen, hScreen, vbSrcCopy)
End Sub
抓屏我会,就是不知道怎样把 *.bmp传输过去
