Basically the type of control You need to use would be an Active-X control.Basically Active-X controls are improved,sophisticated and wrapped versions of OLE controls.I have made a .ocx file available in my word document's file under the listings
"insert->object" using the "insert object type checkbox" of the "Active-X MFC wizard " of "VC++ 6.0" and "VC++2005" both .I therefore think this should also be available into the wizard of your language ,so no need to intangle with the registry.But further if I find it by any means will soon let you know.
It says right in the title of the Counter - Bytes. The scale is just there to get the counter values to fit into the range of 0-100. So 30,000,000 bytes multiplied by a scale of .000001 would give to 30, the bottom of the graph being 0 and the top 100,000,000.
