Reading data from outside world(plz help)

Hi Shahid,
For reading data from parallel port you need to import COM dll Input32.dll which should be inside C:\Windows\System32. The following is the code for importing the DLL

 
using System.Runtime.InteropServices;
 
public class PortOperation
{
[DllImport("inpout32.dll", EntryPoint = "Out32")]
public static extern void Output(int address, int data);//Send Data to Parallel port
[DllImport("inpout32.dll", EntryPoint = "Inp32")]
public static extern int Input(int address);//Read Data from Parallel port
public void ReadDataFromport()
{
int data = Input(889);//889 integer valued address for parallel used for reading
}
public void WriteToPort()
{
Output(888, 64); //888 integer valued address for parallel used for writing to port
}
}
 
Try this and please let me know you have any problem.
 
Regards,
Raaj
