code to insert dynamic block

hello

I need simple code to do just one thing, inserting a dynamic block that is stored in a separate file on my computer (like C:/base/b-22) in the drawing that I'm currently using. For example, I have a windows form with a list box with names of many dynamic blocks that are stored on my c drive, I would like to pick a block with a name and upon a click event of a button or other will go get this block from a separate file and insert it in the drawing I'm currently using, and would need to be able to pick the point of where I want the block to go. Could someone help, I'm using autocad 2010 with visual studio 2008- using the new autocad .net language.

I found this link, http://forums.autodesk.com/t5/NET/Code-to-insert-a-dynamic-block-into-the-current-drawing/m-p/2804900 maybe it can help??

Just to clone a block from another file and insert a reference would be the same if it was dynamic or not.

Here is link to a block manger I posted to get people started with one http://www.theswamp.org/index.php?topic=35280.0

Here is code from that link to bring it in and select a point to insert it.

It has it in VB to
