<DIV>Hi,</DIV>
<DIV>I'am appreciate that you can help me to solve my problems:</DIV>
<DIV>1,When I compiled the follow code,there were 2 errors and 1 warning like this:</DIV>
<DIV>Linking...<BR>LINK : warning LNK4001: no object files specified; libraries used<BR>LINK : error LNK2001: unresolved external symbol _mainCRTStartup<BR>Debug/image1.exe : fatal error LNK1120: 1 unresolved externals<BR>Error executing link.exe.</DIV>
<DIV>2,I had added the lib files to vc workplace:vtkzlib.lib,CommonCxxTests.lib,vtkCommon.lib,vtkDICOMParser.lib,and so on.</DIV>
<DIV>3,What's the problem did I have?</DIV>
<DIV>Here is my code:</DIV>
