DwmUpdateThumbnailProperties (dwmapi)
.
C# Signature:
[DllImport("dwmapi.dll", PreserveSig = true)]
public static extern int DwmUpdateThumbnailProperties(IntPtr hThumbnail, ref DWM_THUMBNAIL_PROPERTIES props);
[StructLayout(LayoutKind.Sequential)]
public struct RECT
{
public int Left, Top, Right, Bottom;
}
[StructLayout(LayoutKind.Sequential)]
public struct DWM_THUMBNAIL_PROPERTIES
{
public int dwFlags;
public RECT rcDestination;
public RECT rcSource;
public byte opacity;
public int fVisible;
public int fSourceClientAreaOnly;
}
'PreserveSig = true' is important, otherwise you'll get stack imbalances.

An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.

ByVal is a VB keyword that specifies a variable to be passed as a parameter BY VALUE. In other words, if the function or sub changes the value of the internal variable, it does not change the value of the external variable that was passed to it.

ByRef is a VB keyword that specifies a variable to be passed as a parameter BY REFERENCE. In other words, the pointer to the variable is passed and any change to its value made within the function or sub will change its value outside the function/sub.
