Upload large files 100mb+ to Sharepoint 2010 via c# Web Service - c#

I am unable to upload large files to Sharepoint 2010. I am using Visual Studio 2010 and Language C#. I have tried multiple ways from content I have found online but nothing has worked. I have changed the settings and config files to the maximum allowed upload limits and still nothing. I am using the copy.asmx for small files which works fine and am trying UploadDataAsync when the file is too large and an exception is thrown but this is not working. Please take a look at the code below...
Any/all assistance is greatly appreciated.

In order to get this to work, you will have to make changes to the SharePoint configuration to increase the upload limit and the time out. The link below shows the necessary steps to get large file uploads to work.

UWP IOT-Core App System.Exception: The application called an interface that was marshalled for a different thread

I'm stuck with an App that is running on Windows 10 IoT Core. All Classes are working fine, except for the one that is creating a CSV File via JSON and is supposed to send it as an Email.
When the Code reaches the "ReturnToMainPage()" Function the Exception "System.Exception: The application called an interface that was marshalled for a different thread" is thrown.
The "funny" thing is, the Mail is being send and i recieve it but the Program won't switch to back to the Main Page as intendet after sending the Email.

This could be an Threading issue. Navigation is only possible on the main-Thread.
You may want to try to marshal the call in:
Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal,
() =>
{
// Your UI update code goes here!
}
);
Source:
The application called an interface that was marshalled for a different thread - Windows Store App
Like Tobonaut said, you can use the Dispatcher.RunAsync to call the Navigation, it worked.
But your problem may not be this.
I copied your code and reproduced your problem and found that you have problems with the calls to read and write files:
// Your code
StorageFile csvFile = await storageFolder.CreateFileAsync(csvName, CreationCollisionOption.OpenIfExists).AsTask().ConfigureAwait(false);
StorageFile file = await KnownFolders.MusicLibrary.GetFileAsync(csvName).AsTask().ConfigureAwait(false);
The Navigation will be work if you delete the .AsTask().ConfigureAwait(false).
Best regards.

You should copy the executable files together with all dll files since it depends on them. You can go to references and then select all libraries and at the atributes, change to copy always, then cleanup the project and then build the project, do not run, copy all content of the folder to a new location and open the executable file, it should run

Please tell me any other way to send sms from desktop application or web application
I dont know way2sms but the easiest SMS API I have found is http://cp.bulksmsportal.co.za/sms_default.aspx
Code is really simple as well
public static void sendSMS(string Recepient, string Message)
{
//Recepient is the cellno in string format
StringBuilder sb = new StringBuilder();
sb.Append("http://www.mymobileapi.com/api5/http5.aspx?");
sb.Append("Type=sendparam");
sb.Append("&username={yourusername}");//add your username here
sb.Append("&password={yourpassword}");//add your password here
sb.AppendFormat("&numto={0}", Recepient);
string message = HttpUtility.UrlEncode(Message, ASCIIEncoding.ASCII);
sb.AppendFormat("&data1={0}", message);
try
{
////Create the request and send data to the SMS Gateway Server by HTTP connection
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(sb.ToString());
//Get response from the SMS Gateway Server and read the answer
HttpWebResponse myResp = (HttpWebResponse)myReq.GetResponse();
System.IO.StreamReader respStreamReader = new System.IO.StreamReader(myResp.GetResponseStream());
string responseString = respStreamReader.ReadToEnd();
respStreamReader.Close();
myResp.Close();
}
catch (Exception ex)

I used this : GSM Communication Library (GSMComm)

Streamreader locks file

I have a c# app (Windows Service) that fires a timer event that reads files in a directory and sends out SMS using the data in the files. Next time the event fires, it tries to move the processed files in the "Processed" directory to a "Completed" directory before processing the new files. I keep getting a "File in use by another process" exception, although I am pretty sure that I dispose of everything that uses the files. If I stop the service and start it again, the files is released. Any ideas?

Any ideas?
You're running a virus checker in an entirely different process. It is detecting that the file has changed and is locking it momentarily in order to check it to see if the edit you just performed to the file introduced a virus. It'll unlock it in a couple of milliseconds.
Disabling your virus checker is a bad idea. Instead, you're just going to have to live with it; write your code to be robust in a world where there are lots of processes vying for locks on files.
StreamReader smsmessage = new StreamReader(filePath);
try
{
FileInfo filenameinfo = new FileInfo(filePath);
....
smsmessage = filenameinfo.OpenText();
...
You are initializing smsmessage twice, but only disposing one of those instances. The first line constructs a StreamReader, and then you overwrite your reference to that instance with the instance created by filenameinfo.OpenText(). That leaves you with an instance that no longer has any references and hasn't been disposed. That instance might be holding a lock on the file and you have no guarantees on when it will be disposed. Even if it isn't holding a lock, you should still fix this.

Response is not available in context? How to solve it?

I save a pdf file to stream. I want to save the stream to Response stream. But it always throw error:Response is not available in contex.
Here is the code:
using System;
using System.Threading;
using System.IO;
using Spire.Pdf;
namespace SingleThreadTest
{
public partial class Test : System.Web.UI.Page
{
//[STAThread]
protected void Page_Load(object sender, EventArgs e)
{
}
[STAThread]
protected void Button1_Click(object sender, EventArgs e)
{
////new a thread
ThreadStart threadStart = HTMLToPDF;
Thread thread = new Thread(threadStart);
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
}
void HTMLToPDF()
{
PdfDocument doc = new PdfDocument();
String url = "http://www.e-iceblue.com/";
doc.LoadFromHTML(url, false, true, true);
Response.ClearContent();
Response.ClearHeaders();
Response.BufferOutput = true;
Response.ContentType = "application/pdf";
using (MemoryStream pdfStream = new MemoryStream())
{
doc.SaveToStream(pdfStream);
using (MemoryStream ms = new MemoryStream())
{
//ms.WriteTo(Response.OutputStream);
Response.OutputStream.Write(pdfStream.ToArray(), 0, pdfStream.ToArray().Length);
}
}
doc.SaveToHttpResponse("Test.pdf", Response, HttpReadType.Save);
doc.Close();
}
}
}
I want to sent client an attachment. How to acheive it??(The above code i use the third component of Spire.PDF).
Thanks in advance.
You are starting new thread to process request, but your original thread likely continues execution and successfully terminates request before your new thread even gets to doing something with the response. You have to wait for completion of the new thread in the original thread (you may be able to creatively use asynchronous pages to not block original thread http://msdn.microsoft.com/en-us/magazine/cc163725.aspx).
I had a similar task. I had a dataset and I needed to return to the client excel file.
I solved with the AXD handler. Add to web config reference to AXD.
See example
<httpHandlers>
<add verb="GET,POST" path="Export.axd" type="YourNameSpace.ExportHandler, YouDLL"/>
</httpHandlers>
See below the code
