.
Summary
The CreateDIBSection function creates a DIB that applications can write to directly. The function gives you a pointer to the location of the bitmap bit values. You can supply a handle to a file-mapping object that the function will use to create the bitmap, or you can let the system allocate the memory for the bitmap.

C# Signature:

[DllImport("gdi32.dll")]
static extern IntPtr CreateDIBSection(IntPtr hdc, [In] ref BITMAPINFO pbmi,
   uint iUsage, out IntPtr ppvBits, IntPtr hSection, uint dwOffset);

VB.NET Signature:

    ByRef ppvBits As Int32, ByVal hSection As Int32, _
    ByVal dwOffset As System.UInt32) As Int32
  End Function
