|Um.... perhaps some common sense is needed here. Zedgraph is in the dll. You take the exe and put it in a folder without the dll, and zedgraph is not present. Surely that's pretty obvious ? The only solution is to move all the zedgraph code into your app, assuming the license allows you to do that, or to distribute it with the dll.
