thanks for your help. Do you have any solution on .net 2003?

Hi Serkan thanks for your help, but yours dll is for .net 2005 but i use .net 2003 so do you have any solution except this.

DataTable tb = new DataTable("TableName"); for( int i=0; i<10; i++ ) { tb.Columns.Add( new DataColumn("ColumnName") ); // ColumnName is also the ID of this column, case-sensitive } for( int j=0; j<10; j++ ) { tb.Rows.Add( tb.NewRow() ); } how to access to the cell: tb.Rows[rowIndex][columnName]

Go enlist in army and they will teach you:cool: 1 line of code equals many bugs. So don't write any!!

I know that it's been a long time since this post has been posted (no pun intended) but I feel that the proper way would be to use the: Microsoft.CSharp.CSharpCodeProvider class. This has several methods which will compile from strings or files, you can compile any form of .NET assembly using this. The equivalent VB is: Microsoft.VisualBasic.VBCodeProvider Hope this enlightens you Ed
