Thread in a web service doesn't start when called it from windows service

I have a windows service,the codes in that body are in a elapsed timer method. I call some web services in a loop,that those web services run in a thread.
I checked the services on servers, they dont start.
And when I take out the codes from thread body,those worked.
This is my windows service code that calls webservices from servers.
private void CallServiceForTrancoding(object sender, System.Timers.ElapsedEventArgs e)
{
DataSet.TranscodingVideosDataTable oTranscodingVideosDataTable = new DataSet.TranscodingVideosDataTable();

You are serializing a task. You surely want to wait for the result, don't you?

I debugged my web service and I found that the issue is related to httpcontext.current in thread is null .
For that I defined HttpContext.Current.Server.MapPath("/video/") as a variable in a class and I recalled it from the webservice.

How to check if all images are completely uploaded into my MVC application folder and then send these images in email body?

I am uploading multiple images to my folder asynchronously using XMLHttpRequest. After the all images are completely loaded to folder I need to send an email which contains these images in the email body part as well as attachment. My question is how do I check if all the images are completely uploaded to my folder. I have tried the following:
$scope.UploadFile = function (inputFile) {
var j = inputFile.length;
var filenames = [];
for (var i = 0; i < inputFile.length; i++) {
$scope.UploadFileIndividual(inputFile[i].file,
inputFile[i].file.name,
inputFile[i].file.type,
inputFile[i].file.size,
i, inputFile.length);
filenames[i] = inputFile[i].file.name;
j--;
}
if (j == 0)
{
$http({
method: 'POST',
url: '/RFQ/SendEmail/',
data: { RFQValues: $scope.RFQData, fileNames: filenames}
}).success(function (response, status, headers, config) {
if (response == true) {
window.location.href = '/CheckOut/ThankYou';
}
}).error(function (response, status, headers, config) {
// alert('Your Selection Not Added to Cart');
});
}
} ;
$scope.UploadFileIndividual = function (fileToUpload, name, type, size, index, fileArrayLength) {
var reqObj = new XMLHttpRequest();
//open the object and set method of call(get/post), url to call, isasynchronous(true/False)
reqObj.open("POST", "/RFQ/UploadFiles", true);
//set Content-Type at request header.For file upload it's value must be multipart/form-data
reqObj.setRequestHeader("Content-Type", "multipart/form-data");
//Set Other header like file name,size and type
reqObj.setRequestHeader('X-File-Name', name);
reqObj.setRequestHeader('X-File-Type', type);
reqObj.setRequestHeader('X-File-Size', size);
// send the file
reqObj.send(fileToUpload);
};
This is my controller method to upload images:
public virtual string UploadFiles(object obj)
{
try
{
var length = Request.ContentLength;
var bytes = new byte[length];
Request.InputStream.Read(bytes, 0, length);
var fileName = Request.Headers["X-File-Name"];
var fileSize = Request.Headers["X-File-Size"];
var fileType = Request.Headers["X-File-Type"];
string path = #"~\images\Client Images";
string subPath = System.Web.HttpContext.Current.Session["UserName"].ToString() + "_" + System.Web.HttpContext.Current.Session["UserId"].ToString();
string finalPath = Server.MapPath(path + #"\" + subPath);
if (!Directory.Exists(finalPath))
Directory.CreateDirectory(finalPath);
var saveToFileLoc = finalPath + #"\" + fileName;
// save the file.
var fileStream = new FileStream(saveToFileLoc, FileMode.Create, FileAccess.ReadWrite);
fileStream.Write(bytes, 0, length);
fileStream.Close();
var usrid = Convert.ToInt32(System.Web.HttpContext.Current.Session["UserId"].ToString());
using (DataContext _db = new DataContext())
{
int RFQId = _db.RFQDetailss.OrderByDescending(x => x.RFQId).Where(x => x.UserId == usrid && EntityFunctions.TruncateTime(x.RFQ_CreatedDate) == EntityFunctions.TruncateTime(DateTime.Now)).Select(y => y.RFQId).FirstOrDefault();
RFQClientImage objClientImage = new RFQClientImage();
objClientImage.RFQId = RFQId;
objClientImage.ImagePath = #"images\Client Images\" + subPath + #"\" + fileName;
_db.RFQClientImages.Add(objClientImage);
_db.SaveChanges();
}
return string.Format("{0} bytes uploaded", bytes.Length);
}
catch
{
return "";
}
}
I have then checked on js side if all files are sent for uploading and then in controller also I am checking if currently uploaded files exists in the folder by following code:
public JsonResult SendEmail(RFQFormInfo RFQValues, string[] fileNames)
{
bool IsMailSent = false;
try
{
string directoryPath = #"~\images\Client Images\";
string subDirectoryPath = System.Web.HttpContext.Current.Session["UserName"].ToString() + "_" + System.Web.HttpContext.Current.Session["UserId"].ToString() + #"\";
//string[] fileEntries = Directory.GetFiles(Server.MapPath(directoryPath + subDirectoryPath));
string targetPath = Server.MapPath(directoryPath + subDirectoryPath);
IsMailSent = checkifImageUploaded(RFQValues, getFilesList(targetPath), fileNames);
return Json(IsMailSent, JsonRequestBehavior.AllowGet);
}
catch
{
return Json(IsMailSent, JsonRequestBehavior.AllowGet);
}
}
public bool checkifImageUploaded(RFQFormInfo RFQValues, IEnumerable<string> fileEntries, string[] fileNames)
{
bool IsMailSent = false;
try
{
int counter = 0;
string directoryPath = #"~\images\Client Images\";
string subDirectoryPath = System.Web.HttpContext.Current.Session["UserName"].ToString() + "_" + System.Web.HttpContext.Current.Session["UserId"].ToString() + #"\";
string targetPath = Server.MapPath(directoryPath + subDirectoryPath);
foreach (string filename in fileNames)
{
var currentFile = Server.MapPath(directoryPath + subDirectoryPath + filename);
foreach(var file in fileEntries)
{
if (file.Equals(currentFile))
{
counter++;
break;
}
}
if (counter == fileNames.Length)
break;
}
if (counter == fileNames.Length)
{
IsMailSent = SendRFQMail(RFQValues, fileNames);
return IsMailSent;
}
else
checkifImageUploaded(RFQValues, getFilesList(targetPath), fileNames);
return IsMailSent;
}
catch
{
return IsMailSent;
}
}
public IEnumerable<string> getFilesList(string targetDirectory)
{
var fileEntries = Directory.EnumerateFiles(targetDirectory);
return fileEntries;
}
but my checkIfImageUploaded() function throws stack overflow exception. I understand it is because my code is ending up into infinite loop or recursion but what I don't understand is at what point is my code ending into infinite recursion and how to solve it.
Please help me out. Thanks in advance.

how to create .txt file and write it c# asp.net

I am trying create and write to a text file in a C# application using the following code
System.IO.Directory.CreateDirectory(Server.MapPath("~\\count"));
using (System.IO.FileStream fs = new System.IO.FileStream("~/count/count.txt", System.IO.FileMode.Create))
using (System.IO.StreamWriter sw = new System.IO.StreamWriter("~/count/count.txt"))
{
sw.Write("101");
}
string _count = System.IO.File.ReadAllText("~/count/count.txt");
Application["NoOfVisitors"] = _count;
but I get an error:
The process cannot access the file 'path' because it is being used by another process.
What is my error?

You're trying to open the file twice; your first using statements creates a FileStream that is not used, but locks the file, so the second using fails.
Just delete your first using line, and it should all work fine.
However, I'd recommend replacing all of that with File.WriteAllText, then there would be no using in your code, it'd be much simpler.
var dir = Server.MapPath("~\\count");
var file = Path.Combine(dir, "count.txt");
Directory.CreateDirectory(dir);
File.WriteAllText(file, "101");
var _count = File.ReadAllText(file);
Application["NoOfVisitors"] = _count;

How to check parent folder

I have get my website path using HttpRuntime.AppDomainAppPath (like this C:/personal/Website/page.aspx)
Web service is always located on page.aspx parent of parent folder (like this C:/personal/Service/service.asmx ). I get the webservice-path using a ABC.dll in servicePath variable like this string servicePath="C:/personal/Service/service.asmx".
How to check service path against website path?
If (GetWebPath()== GetServicePath())
{
// ... do something
}
private string GetWebPath()
{
string path = HttpRuntime.AppDomainAppPath;
string[] array = path.Split('\\');
string removeString = "";
for(int i = array.Length; --i >= 0; )
{
removeString = array[array.Length - 2];
break;
}
path = path.Replace(#"\" + removeString + #"\", "");
return path;
}
private string GetServicePath()
{
string path = #"C:\MNJ\OLK\ABC.asmx"
string[] array = path.Split('\\');
string removeString = "";
for(int i = array.Length; --i >= 0; )
{
removeString = #"\" + array[array.Length - 2] + #"\" + array[array.Length - 1];
path = path.Replace(removeString, "");
break;
}
return path;
}

string webPath = #"C:\blabla\CS_Web\website\";
string servicePath = #"C:\blabla\CS_Web\SPM\Server.asmx";
if(Path.GetDirectory(Path.GetDirectoryName(servicePath))==Path.GetDirectoryName(webPath)
{
//You do something here
}
You have to up page to parent folder using Path.GetDirectoryName()

Try this:
System.Web.Server.MapPath(webPath);
This will return the physical file path of the currently executing web file.
More information can be found here: System.Web.Server

Providing you want to check the following pathes:
string webPath = #"C:\blabla\CS_Web\website\";
string servicePath = #"C:\blabla\CS_Web\SPM\Server.asmx";
you should call
string webPathParentDir = GetParentDirectoryName(webPath);
string servicePathParentDir = GetParentDirectoryName(servicePath);
if (servicePathParentDir.Equals(webPathParentDir, StringComparison.OrdinalIgnoreCase))
{
// ... do something
}
with method:
private string GetParentDirectoryName(string path)
{
string pathDirectory = Path.GetDirectoryName(servicePath);
return new DirectoryInfo(pathDirectory).Parent.FullName;
}

Change filename on file upload in .net (asp)

How to change file name on upload ?
I have such code :
<%# WebHandler Language="C#" Class="Upload" %>
using System;
using System.Web;
using System.IO;
public class Upload : IHttpHandler {
public void ProcessRequest(HttpContext context) {
HttpPostedFile oFile = context.Request.Files["Filedata"];
string newFileName1 = HttpContext.Current.Server.MapPath(#context.Request["orderID"]);
string newFileName2 = HttpContext.Current.Server.MapPath(#context.Request["productCombinationString"]);
string newName;
if(newFileName2 != "" && newFileName2 != null && newFileName2 != "<!--#Ecom:productCombinationString-->") {
newName = newFileName1 + newFileName2 + oFile.ContentType;
} else {
newName = newFileName1 + oFile.ContentType;
}
string sDirectory = HttpContext.Current.Server.MapPath(#context.Request["folder"]);
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
if (!Directory.Exists(sDirectory)) Directory.CreateDirectory(sDirectory);
context.Response.Write("1");
}
public bool IsReusable {
get { return false; }
}
}
And if i change oFile.Filename to newName it does not work ... what is the problem ? :)
Thank you

You can pass your Custom File Name along with Directory to SaveAs Method
oFile.SaveAs(sDirectory + "/" + "abc");

try:
// Get the extension of the uploaded file.
string fileName = Server.HtmlEncode(FileUpload1.FileName);
string extension = System.IO.Path.GetExtension(fileName);
string newName;
if(newFileName2 != "" && newFileName2 != null && newFileName2 != "<!--#Ecom:productCombinationString-->") {
newName = newFileName1 + newFileName2 + extension ;
} else {
newName = newFileName1 + extension ;
}
oFile.SaveAs(sDirectory + "/" + newName );

I haven't tried this code but I do want to point out two things of from the original code:
The first is this order of operations:
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
if (!Directory.Exists(sDirectory)) Directory.CreateDirectory(sDirectory);
I believe it should be this instead. In the above sequence, there is a potential edge case of saving into a non-existing folder. This ensures that the folder is created:
if (!Directory.Exists(sDirectory))
{
Directory.CreateDirectory(sDirectory);
}
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
The other thing is that you might be running into issues with / as the path separator. I think it should be much safer to do something like:
var saveLocation = Path.Combine(sDirectory, oFile.FileName);
oFile.SaveAs(saveLocation);
I hope this helps!

Here is an example i used when saving an image look at the save as section
////saving file in the physical folder;
FileUpload FileUpload1 = file_Image;
string virtualFolder = "~/Resourceimages/";
string physicalFolder = HostingEnvironment.MapPath(virtualFolder);
string PhotoName = ((string)Session["UserName"] + (string)Session["UserSurname"]);
FileUpload1.SaveAs(physicalFolder + PhotoName + FileUpload1.FileName);
string location = virtualFolder + PhotoName + FileUpload1.FileName;
webservice.UpdateResourceImage((int)Session["UserID"], location);
lbl_Result.Text = "Your file " + FileUpload1.FileName + " has been uploaded.";
Image1.Visible = true;
Image1.ImageUrl = location;

string uploadFolder = Request.PhysicalApplicationPath + "UploadFile\\";
if (FileUpload1.HasFile)
{
string extension = Path.GetExtension(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(uploadFolder + "Test"+ extension);
Label1.Text = "File uploaded successfully as: " + "Test"+ extension;
}
else
{
Label1.Text = "First select a file.";
}

private string UpdateFilename(string filename)
