How to add value to a custom column while uploading document into a SharePoint document library as an item using C#?

I have a console application which tries to upload a document into a share point document library list.
I am successfully able to do it and also I am able to fill one of the custom Column(Column name is : "Category") value while uploading the file using C#.
I have tried to fill another custom column(Column name is : "Related Assets") value using the same procedure but i get the error stating the provided column name does not exist but when i see in actual share point portal it does exist.
So not able to solve this issue. Even i tried couple of methods as given below and i get same error message in terms of the column does not exist or it has been deleted or not able to recognize it.
Please find the screenshot of SharePoint showing the list of columns:
Please find the code i have till now which upload the document into SharePoint portal.
public static async Task<string> UploadReleaseNoteDocumentintoSpPortal(string releasenotefilepath, string releasenotefilename, string clientid, string clientsecret)
{
string status = string.Empty;
try
{
Console.WriteLine("Trying to Upload Release note file into Share Point Portal...");
string siteUrl = "<<Sp site URL>>";
Console.WriteLine("Connecting to Share Point Portal...");
var ClientContext = new OfficeDevPnP.Core.AuthenticationManager().GetAppOnlyAuthenticatedContext(siteUrl, clientid, clientsecret);
ClientContext.Load(ClientContext.Web, p => p.Title);
await ClientContext.ExecuteQueryAsync();
Console.WriteLine(ClientContext.Web.Title);
var web = ClientContext.Web;
Console.WriteLine("Connected successfully to Share Point Portal...");
List DocumentsList = web.Lists.GetByTitle("Accelerators Documents");
ClientContext.Load(DocumentsList.RootFolder);
await ClientContext.ExecuteQueryAsync();
Console.WriteLine("Reading and loading the list named : Accelerators Documents from SP");
Console.WriteLine("Converting the release note document into byte array");
byte[] bytes = System.IO.File.ReadAllBytes(releasenotefilepath);
MemoryStream stream = new MemoryStream(bytes);
Console.WriteLine("Storing the release note Data into File Create information object of SharePoint");
FileCreationInformation FileCreateInfo = new FileCreationInformation();
FileCreateInfo.Content = bytes;
FileCreateInfo.ContentStream = stream;
FileCreateInfo.Overwrite = true;
FileCreateInfo.Url = DocumentsList.RootFolder.ServerRelativeUrl + #"\" + releasenotefilename;
Console.WriteLine("Adding file to SharePoint");
var ReleaseNoteFiledata = DocumentsList.RootFolder.Files.Add(FileCreateInfo);
ReleaseNoteFiledata.Update();
ReleaseNoteFiledata.ListItemAllFields["Category"] = "Release Notes";
//ReleaseNoteFiledata.ListItemAllFields["Related Assets"] = "<<Desired Value>>";
//IN Above commented line i get the error stating Microsoft.SharePoint.Client.ServerException:
//'Column 'Related Assets' does not exist. It may have been deleted by another user.
//But in actual site if we see it exists as you can see in above screenshot
ReleaseNoteFiledata.ListItemAllFields.Update();
ClientContext.Load(ReleaseNoteFiledata);
await ClientContext.ExecuteQueryAsync();
Console.WriteLine("Adding file to SharePoint Completed Successfully...");
return status = "Successful";
}
catch (Exception ex)
{
Console.WriteLine("Exception occured while trying to upload Release note file into CoP Portal :" + ex.Message);
return status = "Error/Exception";
}
}
Please find the error message i get while trying to add value to another custom column present in SharePoint:
Microsoft.SharePoint.Client.ServerException: 'Column 'Related Assets' does not exist. It may have been deleted by another user.
Even if i use the ReleaseNoteFiledata.SetFileProperties() and pass the values as a dictionary key value pair containing the column name and its value then also i get the same error for the second custom column. If i keep only the category custom column then it works perfectly without any issue as you can see in the screenshot above.
If i select the record and see the details or properties in the SharePoint the Related assets column symbol is some like in below screenshot:
Please let me know if the supporting documents are fine or still if my issue is not understandable so that i can re frame it or provide more screenshots.
Please help me in solving the above issue or how to make this column recognizable or readable or identifiable in the code.
Thanks in Advance

You need to use the internal name of the column 'Related Assets' in your code. It should be Related_x0020_Assets.
You could check the internal name of the column by go to list settings-> click the column, you would see the internal name in the url.

Vimeo: Get download link from API

I've Vimeo PRO and I'm trying to get the download link so the end user can download the video source. However, the lack of documentation makes it really hard to figure that out.
I'm trying VimeoDotNet but I cannot authenticate, I'm doing the following:
var client = new VimeoClientFactory().GetVimeoClient(key, secret)
var downloadLink = client.GetVideo(video_id).download;
However, the call to GetVideo throws an error saying I have to authenticate first, but I don't see how!
I've also tried with another VimeoClient, but it doesn't seem to implement the download link part.
Can anyone help? Or better yet, share a working example. Thanks.

After 2 days I was finally able to do it, I'll share what I did in case someone needs it. First, download this library:
https://github.com/saeedafshari/VimeoDotNet3
Open in Visual Studio and compile it. It's pretty simple so it compiled right away.
Then reference that compiled DLL from your project and do the following:
var VimeoClient3 = Vimeo.VimeoClient.ReAuthorize(_vimeoAccessToken,
_vimeoAppConsumerKey, _vimeoAppClientSecret);
// videoId is the ID of the video as in the public URL (eg, 123874983)
var result = VimeoClient3.Request("/videos/" + videoId, null, "GET");
if (result == null)
{
throw new Exception("Video not found.");
}
if (result["download"] == null)
{
throw new Exception("Download link not available.");
}
foreach (var item in (ArrayList)result["download"])
{
var downloadLinkInfo = item as Dictionary<string, object>;
if (downloadLinkInfo == null) continue;
// For example, get the link for SD quality.
// As of today, Vimeo was returning an HD quality and a 'mobile' one
// that is for streaming.
if (string.Equals((downloadLinkInfo["quality"] as string), "sd", StringComparison.InvariantCultureIgnoreCase))
{
return downloadLinkInfo["link"] as string;
}
}

How to add an attachment to a test set in ALM OTA via c#?

I run the following code but nothing shows up in ALM:
AttachmentFactory attachmentFactory = (AttachmentFactory)tsTest.Attachments;
TDAPIOLELib.Attachment attachment = (TDAPIOLELib.Attachment)attachmentFactory.AddItem("test");
attachment.Post();
The AddItem method on the second line keeps asking for "object ItemData" but I have no idea what that is exactly. HP has such poor documentation that there is really nothing explaining it. Does anyone know how to programatically using c# add a file attachment to a test run in HP ALM?

After much pain and research I have found an answer. I'm sure there are other ways of accomplishing this that are more efficient but since HP's documentation is the worst on the planet this is the best I could come up with. If anyone has a better way I would LOVE to see it so please post it!
I hope this helps!
try
{
if (qcConn.Connected)
{
string testFolder = #"Root\YourFolder";
TestSetTreeManager tsTreeMgr = (TestSetTreeManager)qcConn.TestSetTreeManager;
TestSetFolder tsFolder = (TestSetFolder)tsTreeMgr.get_NodeByPath(testFolder);
AttachmentFactory attchFactory = (AttachmentFactory)tsFolder.Attachments;
List tsList = tsFolder.FindTestSets("YourTestNameHere", false, null);
foreach (TestSet ts in tsList)
{
TestSetFolder tstFolder = (TestSetFolder)ts.TestSetFolder;
TSTestFactory tsTestFactory = (TSTestFactory)ts.TSTestFactory;
List mylist = tsTestFactory.NewList("");
foreach (TSTest tsTest in mylist)
{
RunFactory runFactory = (RunFactory)tsTest.RunFactory;
Run run = (Run)runFactory.AddItem("NameYouWantDisplayedInALMRuns");
run.CopyDesignSteps();
//runResult just tells me if overall my test run passes or fails - it's not built in. It was my way of tracking things though the code.
if(runResult)
run.Status = "Failed";
else
run.Status = "Passed";
run.Post();
//Code to attach an actual file to the test run.
AttachmentFactory attachmentFactory = (AttachmentFactory)run.Attachments;
TDAPIOLELib.Attachment attachment = (TDAPIOLELib.Attachment)attachmentFactory.AddItem(System.DBNull.Value);
attachment.Description = "Attach via c#";
attachment.Type = 1;
attachment.FileName = "C:\\Program Files\\ApplicationName\\demoAttach.txt";
attachment.Post();
//Code to attach a URL to the test run
AttachmentFactory attachmentFactory = (AttachmentFactory)run.Attachments;
TDAPIOLELib.Attachment attachment = (TDAPIOLELib.Attachment)attachmentFactory.AddItem(System.DBNull.Value);
//Yes, set the description and FileName to the URL.
attachment.Description = "http://www.google.com";
attachment.Type = 2;
attachment.FileName = "http://www.google.com";
attachment.Post();
//If your testset has multiple steps and you want to update
//them to pass or fail
StepFactory rsFactory = (StepFactory)run.StepFactory;
dynamic rdata_stepList = rsFactory.NewList("");
var rstepList = (TDAPIOLELib.List)rdata_stepList;
foreach (dynamic rstep in rstepList)
{
if (SomeConditionFailed)
rstep.Status = "Failed";
else
rstep.Status = "Passed";
rstep.Post();
}
else
{
rstep.Status = "No Run";
rstep.Post();
}
}
}
}
}
}

I have done something similar, but in Python and against Test Steps, so even if I don't have code you can copy & paste it, this might point you to the right direction.
Instead of calling:
attachmentFactory.AddItem( filename )
Call the function with no parameters (or a null paramer, can't tell since I never used the OTA API with C#):
file = attachmentFactory.AddItem()
Now assign the file to the attachment item, and the rest of its properties:
file.Filename = "C:\\Users\\myUser\\just\\an\\example\\path" + fileName
file.Description = "File description"
file.Type=1
file.Post()
The type specifies it's a local file, and not an URL.

If anyone is wondering how to do that on the requirement-module, here is the code:
Req req = Globals.Connection.ReqFactory.Item(*ID*));
VersionControl versionControl = ((IVersionedEntity)req).VC as VersionControl;
versionControl.CheckOut(string.Empty);
AttachmentFactory attFac = req.Attachments;
Attachment att = (Attachment)attFac.AddItem(System.DBNull.Value);
att.Description = "*Your description here";
att.Type = (int)TDAPI_ATTACH_TYPE.TDATT_FILE; //for URL, change here
att.FileName = "*Your path including filename here*";
att.Post();
versionControl.CheckIn("*Your check-in comment here*");

No valuable information on Internet!
After some digging on OTA documentation I have found this:
AttachmentFactory attachmentFactory = (AttachmentFactory)TstTest.Attachments;
TDAPIOLELib.Attachment attachment = (TDAPIOLELib.Attachment)attachmentFactory.AddItem("demoAttach.txt");
attachment.Description = "Bug Sample Attachment";
attachment.Post();
IExtendedStorage exStrg = attachment.AttachmentStorage;
exStrg.ClientPath = "E:\\TestData";
exStrg.Save("demoAttach.txt", true);
actually, was in VB script form but I managed to transform in C#.
OTA reference:
'-----------------------------------------
'Use Bug.Attachments to
' get the bug attachment factory.
Set attachFact = bugObj.Attachments
'Add a new extended storage object,an attachment
' named SampleAttachment.txt.
Set attachObj = attachFact.AddItem("SampleAttachment.txt")
' Modify the attachment description.
attachObj.Description = "Bug Sample Attachment"
' Update the attachment record in the project database.
attachObj.Post
' Get the bug attachment extended storage object.
Set ExStrg = attachObj.AttachmentStorage
'Specify the location of the file to upload.
ExStrg.ClientPath = "D:\temp\A"
'-----------------------------------------
'Use IExtendedStorage.Save to
' upload the file.
ExStrg.Save "SampleAttachment.txt", True

Get list of recently listened music

I'm developing a Windows Phone app that needs to retrieve and manipulate information about the songs played on the device.
I know it is possible to get the song that is currently playing using MediaPlayer.Queue.ActiveSong.
However, what I really need is to have access to a list of recently played tracks.
MediaHistory and MediaHistoryItem classes don't seem to provide this.
Is is really possible? How?

The current API, as #Igor has pointed out in his answer does not allow this. However, there is another way for us to reasonably assume that a particular media file has been played recently, by getting some information about the actual file.
We can use GetBasicPropertiesAsync() along with RetrievePropertiesAsync() which will give us the DateAccessed property for that file.
Here is a code snippet taken from this MSDN page:
public async void test()
{
try
{
StorageFile file = await StorageFile.GetFileFromPathAsync("Filepath");
if (file != null)
{
StringBuilder outputText = new StringBuilder();
// Get basic properties
BasicProperties basicProperties = await file.GetBasicPropertiesAsync();
outputText.AppendLine("File size: " + basicProperties.Size + " bytes");
outputText.AppendLine("Date modified: " + basicProperties.DateModified);
// Specify more properties to retrieve
string dateAccessedProperty = "System.DateAccessed";
string fileOwnerProperty = "System.FileOwner";
List<string> propertiesName = new List<string>();
propertiesName.Add(dateAccessedProperty);
propertiesName.Add(fileOwnerProperty);
// Get the specified properties through StorageFile.Properties
IDictionary<string, object> extraProperties = await file.Properties.RetrievePropertiesAsync(propertiesName);
var propValue = extraProperties[dateAccessedProperty];
if (propValue != null)
{
outputText.AppendLine("Date accessed: " + propValue);
}
propValue = extraProperties[fileOwnerProperty];
if (propValue != null)
{
outputText.AppendLine("File owner: " + propValue);
}
}
}
// Handle errors with catch blocks
catch (FileNotFoundException)
{
// For example, handle a file not found error
}
}
Once you have the DateAccessed property in a variable, we can see if it is a recent date, say, yesterday, or maybe even 2 or 3 days ago. Then we'll know that if it's been accessed within a short period of time, it could have been played.
There are some caveats to this, though. Some virus scanners change the Timestamp properties on files and folders, and they also need to open files to scan them which I would assume would change the DateAccessed property. However, many new Antivirus apps that I've seen revert the Timestamp info back to the original, as if it had never touched the file.
I believe this is the best workaround for this problem at the moment. Unless you only care about when your app recently played a file. Then the answer to that question is as simple as you managing your own recently-played lists for media files.
Update
In order to retrieve the PlayCount for a specified song, you can access that song using the MediaLibrary class:
MediaLibrary library = new MediaLibrary();
Then just access the song like this:
Int32 playCount = library.Songs[0].PlayCount;
where [0] is the index of the song you'd like to get the PlayCount for. An easier way (depending on how you're accessing songs already, might be to do something like:
Int32 playCount = library.Artists[selectedArtistIndex].Albums[selectedArtistAlbumIndex].Songs[selectedSongInAlbumIndex].PlayCount;

Not possible with the current API. MediaHistoryItem only returns last item set by your application, so it is of no use.

Assistance with Oauth2 authentication to use with DropBox

I am building a Windows c# app that needs to upload files to DropBox. Basically I have everything I need for my app(app secret and app key), but I need to have the client tokens saved to my sql DB for future use. According to Dropbox I am unable to save user login info which is good, but finding a good lib is getting tough.I have tried many different DropBox based libraries but run across the following issues:
SharpBox: seems easy enough to use, but need some kind of deserializer to save the client key and client secret anywhere.
OAuth2 Authorizer: Not enough documentation that I can find, in order for me to actually implement this.
DropNet: This is one that looked promising. It's async and looked good, but again I can't find an example of how to perform the auth function and save the variables to a file/DB/Reg/ or anything.
DropBox.API: This is the method that I currently use and it's working. Problem is it's not Async and requires .NET 4.5. I was ok with all the downs but lately found that's it's very touchy about different versions of JSON and other libraries.
I was hoping someone could give me some assistance in getting any of the above OAUTH libs actually working, Just to get the 3 legged auth process working.
UPDATE::
ok so i am going to include some of the code that I am using at the moment, that uses dropbox.api:
// Get Oauth Token
private static OAuthToken GetAccessToken()
{
string consumerKey = "mykey";
string consumerSecret = "myseceret";
var oauth = new OAuth();
var requestToken = oauth.GetRequestToken(new Uri(DropboxRestApi.BaseUri), consumerKey, consumerSecret);
var authorizeUri = oauth.GetAuthorizeUri(new Uri(DropboxRestApi.AuthorizeBaseUri), requestToken);
Process.Start(authorizeUri.AbsoluteUri);
MessageBox.Show("Once Registration is completed Click OK", "Confirmation");
return oauth.GetAccessToken(new Uri(DropboxRestApi.BaseUri), consumerKey, consumerSecret, requestToken);
}
// Complete Oauth function and write to file
private void button5_Click(object sender, EventArgs e)
{
DialogResult result1 = MessageBox.Show("Please register for dropbox before continuing with authentication. The authorization process will take 1 minute to complete. During that time the backup utility window will be unresponsive. Click yes if you are ready to begin the authorization. HAVE YOU REGISTERED FOR DROPBOX YET?", "DO YOU HAVE A DROPBOX ACCOUNT?", MessageBoxButtons.YesNo);
if (result1 == DialogResult.Yes)
{
try
{
u_w.Enabled = false;
var accesstoken = GetAccessToken();
StringBuilder newFile = new StringBuilder();
string temptoken = "";
string tempsecret = "";
string tempprovider = "";
string tempstatus = "";
string[] file = System.IO.File.ReadAllLines(#"C:\cfg\andro_backup.ini");
foreach (string line in file)
{
if (line.Contains("dbkey:"))
{
temptoken = line.Replace("dbkey:", "dbkey:" + accesstoken.Token);
newFile.Append(temptoken + "\r\n");
continue;
}
if (line.Contains("dbsecret:"))
{
tempsecret = line.Replace("dbsecret:", "dbsecret:" + accesstoken.Secret);
newFile.Append(tempsecret + "\r\n");
continue;
}
if (line.Contains("Provider:"))
{
tempprovider = line.Replace("Provider:", "Provider:DropBox");
newFile.Append(tempprovider + "\r\n");
continue;
}
if (line.Contains("Status:"))
{
tempstatus = line.Replace("Status:", "Status:Connected");
newFile.Append(tempstatus + "\r\n");
continue;
}
newFile.Append(line + "\r\n");
}
System.IO.File.WriteAllText(#"C:\cfg\andro_backup.ini", newFile.ToString());
MessageBox.Show("Completed Backup Provider Setup", "Provider Setup Complete");
Configuration.Reload();
The Above works at the moment and I can upload, download files. The issue is it's not Async and I would like to attempt to stay within the .NET 4.0 if possible, this code requires 4.5
Trying to do the same thing with dropnet, I am unable to get it to work at all even using the examples he has given on the page located here https://github.com/dkarzon/DropNet.
I attempted to look at the demos he has on there as well , but they explaing having the user login everytime to perform any functions, where I need the app to be authorized so it can do it's deeds when it needs to. As far as the code I am using for drop net, I literally just copied and pasted what he had there, just to even see if I can get it to connect and still no go.

If you are using DropNet similar to the examples all you need to do is save the return object from the GetAccessToken method. That returns an instance of a UserLogin object which has the Token and secret on it. Or if you are using the async methods for it then the callback parameter.
Checkout the sample here:
https://github.com/dkarzon/DropNet/blob/master/DropNet.Samples/DropNet.Samples.WP7/MainPage.xaml.cs#L69
Post the code you are using for it so I can give you a better explanation for it.
