How to fix a problem with inserting data twice

I have a code that upload files by an fileuploader, as well as a InsertCommand which inserts a data, belonging to that file.
That works fine, but if the string "maxId" has no result, he runs the button-code twice, upload the file twice and finally insert the data twice.
Any Ideas?
See my following code:
if (Bericht_Hochladen.HasFile)
{
SqlCommand commandMaxActionDocID = new SqlCommand("SELECT MAX(actiondoc_id) FROM tbl_action WHERE SUBSTRING(actiondoc_nr, 2, 7) ='" + newNumber.Substring(newNumber.Length - 7) + "'", conn);
string maxId = commandMaxActionDocID.ExecuteScalar().ToString();
if (maxId == "")
{
neue_nr = newNumber.ToString() + "_" + DateTime.Now.ToString("yyyy-MM-dd", ci) + "_" + docart + "_DOC001";
}
else
{
SqlCommand commandMaxActionDocNR = new SqlCommand("SELECT actiondoc_nr FROM tbl_action_1100 WHERE actiondoc_id = #maxId", conn);
commandMaxActionDocNR.Parameters.AddWithValue("#maxId", maxId.ToString());
string NrMitT = commandMaxActionDocNR.ExecuteScalar().ToString();
string count_str = NrMitT.Substring(NrMitT.Length - 3, 3);
int count_int = Int32.Parse(count_str);
count_int = count_int + 1;
count_str = count_int.ToString("000");
neue_nr = newNumber.ToString() + "_" + DateTime.Now.ToString("yyyy-MM-dd", ci) + "_" + docart + "_DOC" + count_str;
}
string dateiendung = Path.GetExtension(Bericht_Hochladen.FileName);
string todaydate = DateTime.Today.ToString("yyyy-MM-dd");

}
catch (Exception ex)
{
//MessageBox.Show(ex.ToString());
}
string del_URL = HttpContext.Current.Server.MapPath("~/TemporaryUploadedFiles/") + dokumentname + dateiendung;
File.Delete(del_URL);

Try changing this line:
string maxId = commandMaxActionDocID.ExecuteScalar().ToString();
To this:
string maxId = Convert.ToString(commandMaxActionDocID.ExecuteScalar());
And for reference:
Difference between Convert.ToString() and .ToString()
I think what's going on is that your ExecuteScalar() is returning something the if statement doesn't recognize, and therefore it's just skipping over it, and then once the data gets added, the value gets populated. Do you have the code that calls the method? That might be helpful.
EDIT:
David, Try changing your control to this:
<div class="pull-left btn-mybtn"> <asp:Button ID="btnDateiHochladen" runat="server" Text="Hochladen" CssClass="font-regular btn-mybtn pull-right"/> </div>
Also, does your code behind (C#) have an OnCommand or OnClick event for this particular button?

How to add a contact to Yahoo using Oauth-2 in Asp.Net C#

I've been wrestling with this for a while now and can't seem to find a solution. The closest I've come is PHP code for Oauth-1 by Joe Chung (https://github.com/joechung/oauth_yahoo), but I can't get my head wrapped around it.
I'm using Asp.Net, and this code is in the ContactController. I have no trouble Getting contacts from Yahoo. The problem is Adding a contact to a user's Yahoo address book. The program proceeds through the Yahoo login process, and there are no errors. But the contact is not saved. I hope someone can take a look at this and tell me what I'm missing.
Thanks.

System.Net.WebException while downloading file

I have a list of mp3 which I am downloading. After some files are downloaded, not all of them - around 5-7, I get WebException. I did a stacktrace and this is the result.
Exception thrown: 'System.Net.WebException' in System.dll
Debug message: The operation has timed out
InnerEx: at System.Net.HttpWebRequest.GetResponse()
at iBlock.Main._InetGetHTMLSearch(String sArtist) in C:\Users\...\Main.cs:line 590
My _InetGetHTMLSearch looks like this
private void _InetGetHTMLSearch(string sArtist)
{
aLinks.Clear();
if (AudioDumpQuery == string.Empty)
{
//return string.Empty;
}
string[] sStringArray;
string sResearchURL = "http://www.audiodump.biz/music.html?" + AudioDumpQuery + sArtist.Replace(" ", "+");
string aRet;
HttpWebRequest webReq = (HttpWebRequest)HttpWebRequest.Create(sResearchURL);
webReq.UserAgent = "Mozilla / 5.0(Macintosh; Intel Mac OS X 10_9_3) AppleWebKit / 537.75.14(KHTML, like Gecko) Version / 7.0.3 Safari / 7046A194A";
webReq.Referer = "http://www.audiodump.com/";
webReq.Timeout = 5000;
try
{
webReq.CookieContainer = new CookieContainer();
webReq.Method = "GET";
using (WebResponse response = webReq.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(stream);
aRet = reader.ReadToEnd();
//Console.WriteLine(aRet);
string[] aTable = _StringBetween(aRet, "<BR><table", "table><BR>", RegexOptions.Singleline);
if (aTable != null)
{
string[] aInfos = _StringBetween(aTable[0], ". <a href=\"", "<a href=\"");

}
}

}
}
catch (Exception ex)
{
Console.WriteLine("Debug message: " + ex.Message + "InnerEx: " + ex.StackTrace);
aLinks.Clear();
return;
//throw exception
}
}
what this method does is simple. A simple search of the sArtist given at audiodump.com
I have a timer which runs very fast, every 10ms.
private void MainTimer_Tick(object sender, EventArgs e)
{
_DoDownload(DoubleDimList[i][y], ref mp3ToPlay);
if (muted) Mute(0);
if (Downloading)
{
StatusLabel.Text = "Downloading: " + DoubleDimList[i][y];
}
}
Now this timer handles the download in the background in a Global scope.
The _DoDownload methos which basically starts the entire process looks like this
private void _DoDownload(string dArtist, ref string dPath)
{
if (!Contain && skip <= 3 && !Downloading)
{
try
{
_InetGetHTMLSearch(dArtist);
if (aLinks.Count < 1)
{
//skip and return
Console.WriteLine("Skipping: " + dArtist);
IniWriteValue(_playlists[i], "Track " + y, dArtist + " -iBlockSkip");
y++;
return;
}
string path = mp3Path + "\\" + dArtist + ".mp3";
if (DownloadOne(aLinks[0], path, false))
{
hTimmer.Start();
Downloading = true;
}
}
catch (Exception Ex)
{
MessageBox.Show("Download start error: " + Ex.Message);
}
}
else if (Downloading)
{
try {
int actualBytes = strm.Read(barr, 0, arrSize);
fs.Write(barr, 0, actualBytes);
bytesCounter += actualBytes;
double percent = 0d;
if (fileLength > 0)
percent =
100.0d * bytesCounter /
(preloadedLength + fileLength);
label1.Text = Math.Round(percent) + "%";
if (Math.Round(percent) >= 100)
{
string path = mp3Path + "\\" + dArtist + ".mp3";
label1.Text = "";
dPath = path;
aLinks.Clear();
hTimmer.Stop();
hTimmer.Reset();
fs.Flush();
fs.Close();
lastArtistName = "N/A";
Downloading = false;
y++;
if (y >= DoubleDimList[i].Count)
{
i++;
}
}
if (Math.Round(percent) <= 1)
{
if (hTimmer.ElapsedMilliseconds >= 3000)
{
string path = mp3Path + "\\" + dArtist + ".mp3";
hTimmer.Stop();
hTimmer.Reset();
fs.Flush();
fs.Close();
System.IO.File.Delete(path);
Contain = false;
skip += 1;
Downloading = false;
}
} }
catch(Exception Ex)
{
MessageBox.Show("Downloading error: " + Ex.Message);
}
}
}
Now once the exception is thrown it messes up the entire project. As you see in the last method, if _InetGetHTMLSearch doesn't update the search(returns nothing) I am skipping and moving to next search. However the exception will be thrown in every next search. I tried setting new cookies in every search but still didn't work.
Any solutions how to avoid this issue?
P.S. I have to say that if I change the timer's Interval to 500ms it will download more mp3 before the exception is thrown but not all of them.
Edit: The issue here is obvious. The request timesout but even if I set it to Timeout.Infinite it will hand there forever

As you can see I have inserted a "header" key-value pair in my returned json repsonse. How do I attach the value of the repsonse headers in the headers property? I have tried webResponse.Headers with no luck.
Thank you very much in advance!
