Bring to the table win-win survival strategies to ensure proactive domination. At the end of the day, going forward, a new normal that has evolved from generation X is on the runway heading towards a streamlined cloud solution. User generated content in real-time will have multiple touchpoints for offshoring.

To get an animation to run in reverse, to say, animate the window closing use some thing like:

The AW_HIDE will make any of the animations run in reverse.

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.

Just add the sample code and a using system.runtime.interopservices;. There is no need to add the import System.Runtime.InteropServices statement in dylan.NET.

The C# code below works fine. However you have to keep in mind to add the namespace "System.Runtime.InteropServices" and keep in mind to write the code into a class.
