    Hello All,

    Recently, I tried the following:

    • Build Qt4.8.3 with Visual Studio 2012
    • Rebuild old project of (Visual Studio 2005 + Qt 4.3.3) with Visual Studio 2012 and Qt4.8.3

    Now, I am getting multiple compilation error in qVector.h. The errors are quoted as below:
    @c:\qt\4.8.3\include\qtcore../../src/corelib/tools/qvector.h(157): error C2182: 'at' : illegal use of type 'void'

    To solve this, i tried to start a new blank project, and later on come to know that error is coming due to inclusion of "QtSql" module in my project. I am really stuck with this, Please guide.

    Thanks & Regards,
    Durgesh

      Hello All,

      Changing from including complete module name to including only the required class names has removed this error.
      For example, earlier I was doing @#include<QtSql>@

      and now I have changed this to @#include<QSqlDatabase>@

      The same is applicable to QtXml Module.

      Anyhow, Now I am unable to connect to database. What can be the possible reasons for this? More information, I am using MS Access as my database.

      Thanks & Regards,
      Durgesh
