Need to edit the code "user info" for sdk ZKTeco device fb100 - zkteco

Question

I have this code working 100% but with one device zkt fb100,This code is for set user name ,card number , with id to the device to register it:
public int sta_SetUserInfo(ListBox lblOutputInfo, TextBox txtUserID, TextBox txtName, ComboBox cbPrivilege, TextBox txtCardnumber, TextBox txtPassword)
{
if (GetConnectState() == false)
{
lblOutputInfo.Items.Add("*Please connect first!");
return -1024;
}
if (txtUserID.Text.Trim() == "" || cbPrivilege.Text.Trim() == "")
{
lblOutputInfo.Items.Add("*Please input data first!");
return -1023;
}
int iPrivilege = cbPrivilege.SelectedIndex;
bool bFlag = false;
if (iPrivilege == 5)
{
lblOutputInfo.Items.Add("*User Defined Role is Error! Please Register again!");
return -1023;
}
/*
if(iPrivilege == 4)
{
axCZKEM1.IsUserDefRoleEnable(iMachineNumber, 4, out bFlag);
if (bFlag == false)
{
lblOutputInfo.Items.Add("*User Defined Role is unable!");
return -1023;
}
}
*/
//lblOutputInfo.Items.Add("[func IsUserDefRoleEnable]Temporarily unsupported");
int iPIN2Width = 0;
int iIsABCPinEnable = 0;
int iT9FunOn = 0;
string strTemp = "";
axCZKEM1.GetSysOption(GetMachineNumber(), "~PIN2Width", out strTemp);
iPIN2Width = Convert.ToInt32(strTemp);
axCZKEM1.GetSysOption(GetMachineNumber(), "~IsABCPinEnable", out strTemp);
iIsABCPinEnable = Convert.ToInt32(strTemp);
axCZKEM1.GetSysOption(GetMachineNumber(), "~T9FunOn", out strTemp);
iT9FunOn = Convert.ToInt32(strTemp);
/*
axCZKEM1.GetDeviceInfo(iMachineNumber, 76, ref iPIN2Width);
axCZKEM1.GetDeviceInfo(iMachineNumber, 77, ref iIsABCPinEnable);
axCZKEM1.GetDeviceInfo(iMachineNumber, 78, ref iT9FunOn);
*/
if (txtUserID.Text.Length > iPIN2Width)
{
lblOutputInfo.Items.Add("*User ID error! The max length is " + iPIN2Width.ToString());
return -1022;
}
if (iIsABCPinEnable == 0 || iT9FunOn == 0)
{
if (txtUserID.Text.Substring(0,1) == "0")
{
lblOutputInfo.Items.Add("*User ID error! The first letter can not be as 0");
return -1022;
}
foreach (char tempchar in txtUserID.Text.ToCharArray())
{
if (!(char.IsDigit(tempchar)))
{
lblOutputInfo.Items.Add("*User ID error! User ID only support digital");
return -1022;
}
}
}
int idwErrorCode = 0;
string sdwEnrollNumber = txtUserID.Text.Trim();
string sName = txtName.Text.Trim();
string sCardnumber = txtCardnumber.Text.Trim();
string sPassword = txtPassword.Text.Trim();
bool bEnabled = true;
/*if (iPrivilege == 4)
{
bEnabled = false;
iPrivilege = 0;
}
else
{
bEnabled = true;
}*/
axCZKEM1.EnableDevice(iMachineNumber, false);
axCZKEM1.SetStrCardNumber(sCardnumber);//Before you using function SetUserInfo,set the card number to make sure you can upload it to the device
if (axCZKEM1.SSR_SetUserInfo(iMachineNumber, sdwEnrollNumber, sName, sPassword, iPrivilege, bEnabled))//upload the user's information(card number included)
{
lblOutputInfo.Items.Add("Set user information successfully");
}
else
{
axCZKEM1.GetLastError(ref idwErrorCode);
lblOutputInfo.Items.Add("*Operation failed,ErrorCode=" + idwErrorCode.ToString());
}
axCZKEM1.RefreshData(iMachineNumber);//the data in the device should be refreshed
axCZKEM1.EnableDevice(iMachineNumber, true);
return 1;
}
But if I have two device what should I change here ? .
I tried to change iMachineNumber to make first device is 1 and second device is 2 but not working too !

Answer 1

Finally I found the solution : in the button connect to device need to insert the above code in loop for one device and then next device and so on .
