想要import這個dll 來做一些控制
有去看了MSDN 但有些地方還是不太懂
跑出來的結果不太對 ...
希望有人可以解決我多天的疑惑 謝謝 <(_ _)>

1F：推 EricTsai:沒人知道你想幹嘛 08/06 16:16
2F：推 eliczone:好 那我來講一下 就是想要用WlanConnect連接到特定網路 08/06 16:35
3F：→ eliczone:而因為WlanConnect裡面的參數又需要WlanOpenHandle()執行 08/06 16:36
4F：→ eliczone:才會得到 而因為function中又需要別的列舉或結構 08/06 16:37
5F：→ eliczone:所以就變成這樣@@" 最終目的就是想要連到特定網路 08/06 16:38
