Hi, All~~~
          vb.net always said , there is no source code available for the current location.
          The reason i know .The source i stroed in c:\aaa folder in first time.... so ok 
          But i always need to move the folder .....
          So i change the source path is c:\bbb\aaa.....
          why Vb.net saved the orginal path, i can't delete the recent projects,
          and i already rebuild the source code in c:\bbb\aaa but also can't to solve... i don't understand
