    在Form中添加一个Picture控件和一个CommandButton控件,在Picture控件中加入一个位图文件,将下面代码加入其中: Private Declare Function GetObject Lib "gdi32" Alias "GetObjectA" _ (ByVal hObject As Long, ByVal nCount As Long, lpObject As Any) _ As Long Private Declare Function GetBitmapBits Lib "gdi32" (ByVal hBitmap As Long, _ ByVal dwCount As Long, lpBits As Any) As Long
  Private Type BITMAP   bmType As Long   bmWidth As Long   bmHeight As Long   bmWidthBytes As Long   bmPlanes As Integer   bmBitsPixel As Integer   bmBits As Long End Type
  Private Sub Command1_Click()   Dim hBitmap As Long   Dim res As Long   Dim bmp As BITMAP   Dim byteAry() As Byte   Dim totbyte As Long, i As Long   hBitmap = Picture1.Picture.Handle
    res = GetObject(hBitmap, Len(bmp), bmp) '取得BITMAP的结构
    totbyte = bmp.bmWidthBytes * bmp.bmHeight '总共要多少BYTE来存图   ReDim byteAry(totbyte - 1)   '将Picture1中的图信息存到ByteAry   res = GetBitmapBits(hBitmap, totbyte, byteAry(0))
    Debug.Print "Total Bytes Copied :"; res   Debug.Print "bmp.bmBits "; bmp.bmBits   Debug.Print "bmp.bmBitsPixel "; bmp.bmBitsPixel '每相素位数   Debug.Print "bmp.bmHeight "; bmp.bmHeight '以相素计算图象高度   Debug.Print "bmp.bmPlanes "; bmp.bmPlanes   Debug.Print "bmp.bmType "; bmp.bmType   Debug.Print "bmp.bmWidth "; bmp.bmWidth '以相素计算图形宽度   Debug.Print "bmp.bmWidthBytes "; bmp.bmWidthBytes '以字节计算的每扫描线长度 End Sub
