    Hello All,

    CVctrInfoBlk.ob j - 0 error(s), 8 warning(s)

    I have compiled in MS VC 6.0 compiler.

    Here is header file cvariantinfo.h and the warning occurs exactly at the
    line where is declare a static vector<string>

    #ifndef CVARIANTINFO_H
    #define CVARIANTINFO_H

    #include <vector>
    #include <string>

    class CVariantInfo
    {
    public:
    static vector<uint32> m_VDSVctrEntrie s;
    static vector<uint32> m_VDSBlkLength;
    static vector<uint32> m_VDSIndex;
    static vector<string> m_VDSFileName; //warning occurs here
    static uint32 m_ulBlkLength;
    };

    #endif

    Thanks in advance.

    Regards,
    Naren.

      Template expansions produce some very long names - not a real problem
      though. You can get rid of the warning with:

      #pragma warning(disable :4786)

      BTW with Visual C++ you can click on an error message and press F1 to get
      more information about it ...

          There is nothing you need to worry about. This is just an VC++ feature in
          the debug version, telling you that the internal symbols reached the limit
          of 255 characters and thus are truncated for the browse-information
          database. To turn this annoying stuff off you will have to resort to a
          #pragma statement. I don't know the exact syntax by heart but it should be
          something like

          #pragma warning off (C4786)

          Please, check your manual for the correct syntax!!

          Regards
          Chris
