C# Merge Splitted File

Hi all, here a very easy lwebcode free script to split file in C#

// calls example
...

int iSplittedFileSize = 1024 * 8;MergeFile(@"C:\script\", iSplittedFileSize, @"C:\LwebCodeMergeFile\");

...

public static void MergeFile(string inputfoldername1, string SaveFileFolder)
        {
            string[] tmpfiles = Directory.GetFiles(inputfoldername1, "*.tmp");

            FileStream outPutFile = null;
            string PrevFileName = "";

            foreach (string tempFile in tmpfiles)
            {
                string fileName = Path.GetFileNameWithoutExtension(tempFile);
                string baseFileName = fileName.Substring(0, fileName.IndexOf(Convert.ToChar(".")));
                string extension = Path.GetExtension(fileName);

                if (!PrevFileName.Equals(baseFileName))
                {
                    if (outPutFile != null)
                    {
                        outPutFile.Flush();
                        outPutFile.Close();
                    }
                    outPutFile = new FileStream(SaveFileFolder + "\\" + baseFileName + extension, FileMode.OpenOrCreate, FileAccess.Write);

                }

                int bytesRead = 0;
                byte[] buffer = new byte[1024];
                FileStream inputTempFile = new FileStream(tempFile, FileMode.OpenOrCreate, FileAccess.Read);

                while ((bytesRead = inputTempFile.Read(buffer, 0, 1024)) > 0)
                    outPutFile.Write(buffer, 0, bytesRead);

                inputTempFile.Close();
               
                PrevFileName = baseFileName;

            }
        }

C# Windows Service Debug

Hi all, here an easy example to make a debug on C# Windows Service ,
Implementation of Code founded on:

https://www.codeproject.com/Articles/14353/Creating-a-Basic-Windows-Service-in-C

With this useful example you create a Single *.exe file , but if you start the debugger
you can't debug the code with Visual Studio, Here is how to do:

First, make all step writed on CodeProject(in future reference I call this project "CodeProjectWS"), after you need to do this:

Right Clik on Current Solution -> Add -> New Project
On Project Type select Windows Consolle Application
select a name for new project, I choose :"LwebCodeWinDbg" -> Ok
Now in New Project "LwebCodeWinDbg" right-click the project name and go to:
[Add]->[Class]. Name the class "LwebCodeWindowsService.cs" and then hit OK.
Open class "LwebCodeWindowsService" and put this code:

namespace LwebCodeWinDbg
{
    public class LwebCodeWindowsService
    {
        public static void WindowsServiceStart()
        {
            System.IO.File.WriteAllText("c:\\LwebCodeTetsService.txt", DateTime.Now.ToString());
        }
    }
}
   
Now in New Project "LwebCodeWinDbg" open Program.cs and paste this code over Main Function:

namespace LwebCodeWinDbg
{
    class Program
    {
        static void Main(string[] args)
        {
            //put debug breakpoint on this istruction:
            LwebCodeWindowsService.WindowsServiceStart();
        }
    }
}

Now Open "CodeProjectWS" , right Clik on "Reference"-> Add Reference
in left pane select: "Solution"    -> Browse... and browse to "LwebCodeWinDbg" Project and then hit OK.
Open WindowsService.cs
and paste this code on OnStart Event:

protected override void OnStart(string[] args)
        {
            base.OnStart(args);
            LwebCodeWinDbg.LwebCodeWindowsService.WindowsServiceStart();
        }

with this istruction you can call the same function from Windows Service and Windows Consolle Application.
To debug the Windows service right click on "LwebCodeWinDbg" -> Set as Startup Project
F5 to start debug.

Hope it helps

Javascript read JSON file and loop through records(optional with JQuery)

Hi all, here a very fast example on how to read json data from file in Javascript,
here the content of *.htm file:

<!DOCTYPE html>
<html>
<head>
    <title>LWebCode Javascript Read JSON from file</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>
    <script type="text/javascript" src="mydata.json"></script>
    <script>
        function ReadData()
        {
            var dataLstAz = JSON.parse(jsLstData);
            alert(jsLstData.length);
          
            for (var key=0, size=jsLstData.length; key<size; key++)
            {
                var obj = jsLstData[key];
                liout = obj.Name + ", " + obj.Age + "<br/>";
                $("#Output").append(liout);
            }
        }
      
        $( document ).ready(function() {
            ReadData();
        });
    </script>
</head>
<body>
    <div id="Output">
    </div>
</body>
</html>

Here the content of "mydata.json" file,
put this file in same folder of *.htm file, or change path in *.htm file:

jsLstData = '[{"Name":"MyName1","Age":"20"}, {"Name":"MyName2","Age":"22"}]';
//End of file "mydata.json"

Now simply open *.htm file in browser and you'll get this output:

MyName1 20
MyName2 22

That's it, hope it helps
