Hi Erel,
I 'm just download Thaispeak.exe app from a website. There are many dll files,I need to use B4J to coding. Can B4J manage the dll files,cann't it?
No.B4J being Java cannot interface directly to native Windows dlls nor can it call the Windows API nor can it use COM. You can use JNA to do some of this but it is low level and complex making it difficult.
