我的代码是这样的
m_hdc1 = CreateCompatibleDC(0)
m_dib1 = CreateDIBSection(m_hdc1, bmpinfo, 0, m_ptr1, 0, 0)
...
BitBlt m_hdc1, 0, 0, 64, 64, Picture2.hdc, 0, 0, vbSrcCopy
Dim Data() As Byte, a As Long
ReDim Data(m_pitch1 * m_height - 1)
GetBitmapBits m_dib1, m_pitch1 * m_height, Data(0)
Dim Data1() As Byte
ReDim Data1(m_pitch1 * m_height - 1)
CopyMemory Data1(0), m_ptr1, m_pitch1 * m_height
用GetBitmapBits 方法得到的数组是正确的，但是CopyMemory 从ptr1里得到的数组缺不正确。
求教这个createdibsection 的指针参数是怎么用的啊？
