I'm connected to the biometric device IP and Port but I don't how to get Attendance log using zkemkeeper ?

I'm using the code below and have a message input string was not in a correct format

What I have tried:

try
           {
               ShowStatusBar(string.Empty, true);

               ICollection<MachineInfo> lstMachineInfo = manipulator.GetLogData(objZkeeper, int.Parse(tbxMachineNumber.Text));

               if (lstMachineInfo != null && lstMachineInfo.Count > 0)
               {
                   BindToGridView(lstMachineInfo);
                   ShowStatusBar(lstMachineInfo.Count + " records found !!", true);
               }
               else
                   DisplayListOutput("No records found");
           }
           catch (Exception ex)
           {
               DisplayListOutput(ex.Message);
           }

"and have a message"
Please explain where this message occurs, and what data and variables are involved.

Studying the zzkkemkeeper documentation would be a good place to start.
