I have an exception and I couldn't find a solution for my problem. I think my whole code is valid c#.
namespace YoutubeDownloader2Form

}
private async void button1_Click(object sender, EventArgs e)

int i = 0;
foreach (var Urls in FinalLiast)
{
string Authorization = Urls.Author;
IEnumerable<VideoInfo> videoInfos = DownloadUrlResolver.GetDownloadUrls(Urls.Url);
VideoInfo Video = videoInfos.First(info => info.VideoType == VideoType.Mp4 && info.Resolution == 144);
if (Video.RequiresDecryption)
{
DownloadUrlResolver.DecryptDownloadUrl(Video);
}
string path = Directory.CreateDirectory(#"C:\Youtube\" + Authorization).ToString();
var videoDownloader = new VideoDownloader(Video,
Path.Combine((#"C:\youtube\" + path), Video.Title + Video.VideoExtension));
StreamWriter dosya = File.AppendText((#"C:\youtube\" + path) + i + ".txt");
videoDownloader.Execute();
//Thread.Sleep(60000);
i++;
}
}
}
}
public class DownloadUrl

List<Class1> ListClass1 = new List<Class1>();
string searchCount =
txtboxDeger + "&sp=EgIYAVAU";
foreach (var Item in Items.SearchQuery(searchCount, 1))
{
Class1 Video = new Class1();
Video.title = Item.Title;
Video.Author = Item.Author;
Video.Url = Item.Url;
IEnumerable<VideoInfo> videos = DownloadUrlResolver.GetDownloadUrls(Video.Url);

}
return ListClass1;
}
}

You can see from picture where the code throws. I tried asynchronously, and it also throws. I checked the InnerException; it says that the given path's format is not supported. But, it downloaded first three videos successfully. It should work fine for other videos too.
Why is this code throwing an exception?
I followed these tutorials to write this code:

I have this class where I am selecting two values from the database and comparing it to the textbox values provided by the users. Below is my class.
public void Userlogin(TextBox username, TextBox pwd)
{
int _failedAttempt = 0;
OpenConnection();
command = new OracleCommand();
command.CommandText = "SELECT username, user_pwd FROM dinein_system_users WHERE username:usrname AND user_pwd:pwd";
command.Connection = dbconnect;
command.BindByName = true;
try
{
command.Parameters.Add("usrname", username.Text);
command.Parameters.Add("pwd", pwd.Text);
}
catch (NullReferenceException NRE)
{
MessageBox.Show("Please contact your developer about this error. Thank you " + NRE);
}
_reader = command.ExecuteReader();
if (_reader.Read() != true)
{
_failedAttempt = _failedAttempt + 1;
while (_failedAttempt < 3)
{
MessageBox.Show("Incorrect Username or Password. Please try again " + "Attempts: " + _failedAttempt);
username.ResetText();
pwd.ResetText();
}
}
else
{
MessageBox.Show("Welcome");
}
}
my connection string
this._connectionString = "Data Source=xe;Max Pool Size=50;Min Pool Size=1;Connection Lifetime=120;Enlist=true;User Id=hr;Password=hr";
So when the program is executed I am getting this error
An unhandled exception of type 'Oracle.DataAccess.Client.OracleException' occurred in Oracle.DataAccess.dll
Additional information: External component has thrown an exception. I have been at this for the past hour any help would be appreciated.
Update
Open Connection method

return;
}

dbconnect.Dispose();
dbconnect = new OracleConnection(this._connectionString);
dbconnect.Open();
return;
}
}

Rather than using your separate OpenConnection() method, consider coding with the using() statement. It will ensure that your connection an other database-related objects are always disposed.
For example:
int _failedAttempt = 0;
public void Userlogin(TextBox username, TextBox pwd)
{
try
{
using (var connection = new OracleConnection(_connectionString))
{
connection.Open();
using (var command = new OracleCommand())
{
command.CommandText = "SELECT username, user_pwd FROM dinein_system_users WHERE username= :usrname AND user_pwd= :pwd";
command.Connection = connection;
command.BindByName = true;
command.Parameters.Add("usrname", username.Text);
command.Parameters.Add("pwd", pwd.Text);
using (var reader = command.ExecuteReader())
{
if (reader.Read() != true)
{
_failedAttempt += 1;
if (_failedAttempt < 3)
{
MessageBox.Show("Incorrect Username or Password. " +
"Please try again. " +
$"Attempts: {_failedAttempt}");
username.ResetText();
pwd.ResetText();
}
else
{
// 3 failed attempts
}
}
else
{
_failedAttempt = 0;
MessageBox.Show("Welcome");
}
}
}
}
}
catch(OracleException ex)
{
MessageBox.Show("Error: {ex}");

I am using a backgroundworker and I think there is a cross thread thing.. But I cant solve it.
my code is here
private void bgworkerGameLoad_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
var arg = e.Argument.ToString();
var liste = webHelper.ShowGame("http://www.abx.com/" + arg);
txtHowToPlay.Invoke(new Action(() => txtHowToPlay.Text = String.Format("Oyun Bilgi: {0}", liste[0])));
txtInfo.Invoke(new Action(() => txtInfo.Text = String.Format("Nasıl Oynanır: {0}", liste[1])));
bgworkerGameLoad.ReportProgress(0,liste[2]);

url= e.UserState.ToString();
Thread.Sleep(2);
}));
axShockwaveFlash1.Movie = url;
LoadFlash();
pbWaitForChannelLoading.Visible = false;
axShockwaveFlash1.Play();
}
the problem is that I cant get the e.UserState.ToString() for my shocwaveplayer. I used a local string variable but its the same result.
it is occured targetofaninvocation exception in program.cs
Application.Run(new FrmMain());;
but that code is in frmMain.cs
this is detail of the exception

InnerException:
what is my mistake? I tried to use delegate but its the same..
It sounds like the problem is as simple as e.UserState being null. You don't even need to use Invoke to get at UserState - you'll see the same problem if you just have:
if (FlashPlayerActive)
UnLoad();
string url = e.UserState.ToString();
Thread.Sleep(2); // This is generally a bad idea anyway, btw...
Where are you setting the UserState? I suspect you're not setting it anywhere, so it's still null, which is why you're getting an exception.
I solved the problem..
I hadnt added axShockwaveFlash1 to my form before set values..
in LoadFlash function, it was
public void LoadFlash()
{
axShockwaveFlash1 = new AxShockwaveFlash();
axShockwaveFlash1.BeginInit();
axShockwaveFlash1.Location = new Point(14, 196);
axShockwaveFlash1.Name = "Test Movie";
axShockwaveFlash1.TabIndex = 0;
axShockwaveFlash1.Movie = liste[2];
axShockwaveFlash1.EmbedMovie = true;
axShockwaveFlash1.AutoSize = true;
axShockwaveFlash1.Size = new Size(640, 480);
axShockwaveFlash1.Visible = true;
axShockwaveFlash1.EndInit();
splitContainerControl.Panel2.Controls.Add(axShockwaveFlash1);
FlashPlayerActive = true;
}
but i changed this code like
public void LoadFlash()
{
axShockwaveFlash1 = new AxShockwaveFlash();
splitContainerControl.Panel2.Controls.Add(axShockwaveFlash1);
axShockwaveFlash1.BeginInit();
axShockwaveFlash1.Location = new Point(14, 196);
...
it works..

In my program I fetch GeoRSS from a website every 10th second. As long as no new items are added to the GeoRSS feed, the program works fine (i.e. I can fetch and parse the rss properly - also when the elements of the existing rss items change their value). However, as soon as a new item is added to the rss feed, I get the following error:
Unexpected end of file while parsing Name has occurred. Line 85, position 13.

UpdateTimer.Tick += (evtsender, args) =>
{
LoadRSS(url.Trim());
};
UpdateTimer.Start();
}
}
private static void LoadRSS(string uri)
{
Trace.WriteLine("Fetching rss feed");
WebClient wc = new WebClient();
wc.OpenReadCompleted += wc_OpenReadCompleted;
Uri feedUri = new Uri(uri, UriKind.Absolute);
wc.OpenReadAsync(feedUri);

Does anyone have an idea what's causing the error, and how I can prevent it from happening?
sounds like when you get an update you are just adding it to the end of what you already have, possibly outside of the wrong ending tag?

I am trying to read a public folder hosted in ExchangeServer 2010 SP1. Well I am able to connect but when I am trying to read the folder I am getting stragne error. Hope somebody will able to share his/her experience. Below is the code what I am executing doing and after that the error SoapException was Unhandled I am getting.
ExchangeServiceBinding serviceBinding = new ExchangeServiceBinding();
serviceBinding.Credentials = new NetworkCredential("XXXXXXXX", "YYYYYY", "zzzzzzzz");
serviceBinding.RequestServerVersionValue = new RequestServerVersion();
serviceBinding.RequestServerVersionValue.Version = ExchangeVersionType.Exchange2010_SP1;
serviceBinding.Url = #"https://the.domain.of.my.work/EWS/exchange.asmx";
DistinguishedFolderIdType publicFolderRoot = new DistinguishedFolderIdType();
publicFolderRoot.Id = DistinguishedFolderIdNameType.publicfoldersroot;
FindFolder(serviceBinding, publicFolderRoot, #"All Public Folders");
private static FolderIdType FindFolder(ExchangeServiceBinding esb, BaseFolderIdType folderId, string folderName)
{
//FindPublicFolderType request = new FindPublicFolderType();
FindFolderType request = new FindFolderType();
request.Traversal = FolderQueryTraversalType.Shallow;
request.FolderShape = new FolderResponseShapeType();
request.FolderShape.BaseShape = DefaultShapeNamesType.AllProperties;
request.ParentFolderIds = new BaseFolderIdType[] { folderId };
//Giving error at this below
FindFolderResponseType response = esb.FindFolder(request);
foreach (ResponseMessageType rmt in response.ResponseMessages.Items)
{
if (rmt.ResponseClass == ResponseClassType.Success)
{
FindFolderResponseMessageType ffResponse = (FindFolderResponseMessageType)rmt;
if (ffResponse.RootFolder.TotalItemsInView > 0)
{
foreach (BaseFolderType subFolder in ffResponse.RootFolder.Folders)
if (subFolder.DisplayName == folderName)
return subFolder.FolderId;
return null;
}
Console.WriteLine("Can't find '" + folderName + "'.");
}
else
{
//Console.WriteLine("Response was: " + rmt.ResponseClass + Environment.NewLine + rmt.MessageText);
MessageBox.Show("Response was: " + rmt.ResponseClass + Environment.NewLine + rmt.MessageText);
}
}
return null;
}
After executing the above code I am facing error mentioned below
