Vb.net - Zkteco SDK Function to Change User Status

To change the user status using the ZKTeco SDK in VB.NET, you typically interact with the SDK's functions to update user information stored in the device's database. Here's a general outline of how you can achieve this:

Prerequisites

Ensure you have the ZKTeco SDK installed and referenced in your VB.NET project. You'll also need access to the ZKTeco device's IP address or connection details.

Example Code

Below is a simplified example demonstrating how to change the user status using ZKTeco SDK functions in VB.NET. This example assumes you have already initialized the SDK and connected to the ZKTeco device.

Imports zkemkeeper Public Class ZKTecoUserOperations Private axCZKEM1 As New CZKEM ' Initialize ZKTeco SDK Public Sub ChangeUserStatus(ByVal userId As Integer, ByVal newStatus As Integer) ' Connect to the device (replace IP and port with your device's details) If axCZKEM1.Connect_Net("DeviceIPAddress", 4370) Then ' Change user status If axCZKEM1.SSR_SetUserInfo(1, userId.ToString(), "", newStatus, True) Then Console.WriteLine("User status updated successfully.") Else Console.WriteLine("Failed to update user status.") End If ' Disconnect from the device axCZKEM1.Disconnect() Else Console.WriteLine("Failed to connect to the device.") End If End Sub End Class

Explanation:

  1. Imports Statement: Imports the zkemkeeper namespace, which contains the definitions for ZKTeco SDK functions.

  2. ZKTeco SDK Initialization: Private axCZKEM1 As New CZKEM initializes an instance of the CZKEM class provided by the SDK.

  3. ChangeUserStatus Function:

    • ChangeUserStatus method takes userId (integer) and newStatus (integer) as parameters.
    • Connect_Net connects to the ZKTeco device using its IP address and port (replace "DeviceIPAddress" and 4370 with your device's actual details).
    • SSR_SetUserInfo is used to set or update user information. The parameters are:
      • 1: Machine number (typically 1 for a single device).
      • userId.ToString(): User ID as a string.
      • "": Empty string for the user's name (optional).
      • newStatus: New status for the user (e.g., 1 for active, 0 for inactive).
      • True: Whether to overwrite existing data.
    • Outputs success or failure messages based on the SDK functions' return values.

  4. Disconnect: Disconnect method disconnects from the ZKTeco device after operations are completed.

Notes:

  • SDK Functions: The specific functions (Connect_Net and SSR_SetUserInfo) and parameters used may vary slightly depending on the ZKTeco SDK version and device model. Refer to the SDK documentation or provided SDK samples for exact usage.

  • Error Handling: Implement additional error handling as needed to manage connection failures, invalid user IDs, or other potential issues.

  • Device Configuration: Ensure your device is configured to allow remote connections and that you have the correct IP address and port configured in Connect_Net.

  • Testing: Test the integration with your ZKTeco device to ensure proper functionality and error handling in various scenarios.

By following this approach, you can effectively change the user status using the ZKTeco SDK functions in your VB.NET application. Adjust the code based on your specific requirements and the SDK version you are using.
