Well, I think your problem is trying to write a "real time" (whatever you mean by that) app in C#. Also, there is no method inlining in C# unless the JIT compiler feels...

Hello, i'm trying to do this Code: chargedataGridView.CurrentRow.Index = 5; and i get this Code: Property or indexer 'System.Windows.Forms.DataGridViewBand.Index' cannot be assigned to -- it is read only error, does anyone know why ???
