Daily Screenshot sends email automatically every hour or once a day with one of following attachment:

— Screenshot of a website

— Screenshot of running computer

Beside attachment website URL or name of comuputer will be sent via email. This tool can be so configured that it will start and will be active on Windows start up. Daily Screenshot can only be closed by the exit button that opens when the icon in the taskbar is pressed with the right mouse button.

YR Drive Easy Connect

In order to use this application you need to buy a device from Yılmaz Redüktör (www.yr.com.tr)

• Read and write parameters of Yılmaz Motor Drivers
• Connection to RS485 (Modbus) of motor driver via Bluetooth
• Monitor some parameters of motor driver
• Save and load parameter sets
• Copy parameters from one drive to an other drive

Delta PLC provides Modbus communication library DMT, which can be used in C# ​​to communicate with Delta PLC over RS485 (Modbus).

First of all to use DMT with your application following functions should be imported from kernel32.dll and DMT.dll:

using System.Reflection;[DllImport("kernel32.dll", CharSet = CharSet.Auto)]static extern IntPtr LoadLibrary(string dllPath);[DllImport("kernel32.dll", CharSet = CharSet.Auto)]static extern bool FreeLibrary(IntPtr hDll);// Serial Communication[DllImport("DMT.dll", CharSet = CharSet.Auto)]static extern int OpenModbusSerial(int conn_num, int baud_rate, int data_len, char parity, int stop_bits, int modbus_mode);[DllImport("DMT.dll", CharSet = CharSet.Auto)]static extern void CloseSerial(int conn_num);// MODBUS Address Calculation[DllImport("DMT.dll", CharSet = CharSet.Auto)]static extern…

Secure Instant Messaging has following features:

• Secure IP Messaging with private\public keys
• RSA decryption/encryption
• Generate key pair and save keys as files

In cryptography, Triple DES (3DES or TDES) is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block.

To use 3DES functionality first off all we need to include “System.Security.Cryptography”.

using System.Security.Cryptography;

Then we should create and adjust an object which will do encryption:

var tdese = TripleDES.Create();tdese.Mode = CipherMode.ECB;tdese.Padding = PaddingMode.PKCS7;tdese.Key = ConvertHexStringToByteArray("AABBCCDDEE11223344556677889900FF");var encryptor = tdese.CreateEncryptor();

“ConvertHexStringToByteArray” function to convert hex string to byte array:

public static byte[] ConvertHexStringToByteArray(string hexString)
{
            if (hexString.Length % 2 != 0)…

A IoT device programmed with Arduino need connect to WiFi at start of device to use internet for data transfer etc. First of all we need to include header file “WiFiClient” to our sketch.

#include <WiFiClient.h>

With code below we will let user enter WiFi credentials over serial communication. we should add this code to our setup() part of our Arduino sketch.

Serial.write("Please enter name of your wifi network\n");while(Serial.available() == 0){};String Uid=Serial.readStringUntil('\n');Serial.write("Please enter password of your wifi network\n");while(Serial.available() == 0){};String pass= Serial.readStringUntil('\n');

If you want give user a tool to setup WiFi over serial you…

In this video i will give 4 simple examples of using LabVIEW.
