Dim myRow   As Data DataRow myRow   dt Select  MyColumnName    SomeColumnTitle    myRow 0   SomeOtherColumnTitle     strValue   Code above instantiates a DataRow   Where  dt  is a DataTable  you get a row by selecting any column  I know  sounds backwards    Then you can then set the value of whatever row you want  I chose the first row  or  myRow 0     for whatever column you want

The problem you re running into is that you re trying to replace an entire row object   That is not allowed by the DataTable API   Instead you have to update the values in the columns of a row object   Or add a new row to the collection    To update the column of a particular row you can access it by name or index   For instance you could write the following code to update the column  Foo  to be the value strVerse  dtResult Rows i   Foo     strVerse

You can access columns by index  by name and some other ways   dtResult Rows i   columnName     strVerse   You should probably make sure your DataTable has some columns first
