So I have something very strange happening in my Asp.Net Website.
I have 2 seperate pages with the same code to download files stored in a SQL database.
One page is an admin version of the page where you can delete and upload files and also see the files ID.
The user end version of this page only displays the download button and the filename. The ID is hidden and used as a DataKey in the grid to select the file from the database.
Both pages work perfectly in development. But when I switched to our production staging server the user end version of the page will turn a simple one line text file into a bunch of gargly-goop PDF encoding when saving and opening it, while the admin version of the page still functions properly. PDF's download and view normal and word documents do the same thing that the text files do.
Here is the code behind for the admin download section:
protected void btnSaveAttachment_Click(object sender, EventArgs e)
{
GridViewRow selectedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
string AttachmentID = "";
string AttachmentName = "";
if (selectedRow.Cells[1].Text != null && selectedRow.Cells[2].Text != null)
{
AttachmentID = selectedRow.Cells[1].Text;
AttachmentName = selectedRow.Cells[2].Text;
}
byte[] objData = Utility.SaveAttachmentBytes(AttachmentID);
HttpResponse response = HttpContext.Current.Response;
response.ClearContent();
response.Clear();
response.ClearHeaders();
response.AddHeader("Cache-Control", " no-store, no-cache ");
response.AddHeader("Content-Disposition", "attachment; filename=" + AttachmentName + ";");
response.BinaryWrite(objData);
response.Flush();
if (response != null)
{
response.End();
}
}
Here is the code behind for the user download section:
protected void btnSaveAttachment_Click(object sender, EventArgs e)
{
GridViewRow selectedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
//string AttachmentID = selectedRow.Cells[1].Text;
string AttachmentID = grdAttachments.DataKeys[0].Value.ToString();
string AttachmentName = "";
if (selectedRow.Cells[1].Text != null)
{
AttachmentName = selectedRow.Cells[1].Text;
}
byte[] objData = Utility.SaveAttachmentBytes(AttachmentID);
HttpResponse response = HttpContext.Current.Response;
response.ClearContent();
response.Clear();
response.ClearHeaders();
response.AddHeader("Cache-Control", " no-store, no-cache ");
response.AddHeader("Content-Disposition", "attachment; filename=" + AttachmentName + ";");
response.BinaryWrite(objData);
response.Flush();
//File.Delete(SavePath);
if (response != null)
{
response.End();
}
}
I am at a point where I just dont know what the heck is going on. The only other difference in the pages front end code is the user page load some text from the database into a label and has a telerik textbox control. (I have tried stripping out all other items on the page but still files other than PDF try to encode as a PDF.)
Here is what a 1 line text file looks like when saving and opening it.

RESOLVED
The issue was the DataKeys[0] was always selecting the 0 item in the array of keys. I changed that to:
string AttachmentID = grdAttachments.DataKeys[selectedRow.RowIndex].Value.ToString();
And now all is working fine! Wish I would have debugged closer into the attachmentID!
It just so happened that there was 2 documents that were the same and I though I was downloading the correct document.
In your admin section:
string AttachmentID = selectedRow.Cells[1].Text;
In your user section:
string AttachmentID = grdAttachments.DataKeys[0].Value.ToString();
I would have to assume that the user section assignment is not doing what you expect it to, since the logic isn't the same for both. Verify what AttachmentID is set to in each case, perhaps via logging.

I have a datatable filled by date , day ,name and type so I read from this datatable into List> using C#.net so
the code is this :
dicArray = dtrd.AsEnumerable()
.Select(Row => Row["IDp"]).Distinct()
.Select(Id => new KeyValuePair<string, string[]>(
Id.ToString(),
dtrd.AsEnumerable()
.Where(Row => Row["IDp"].ToString() == Id.ToString())
.Select(Row => Row["date"].ToString()+";"+ Row["day"].ToString()+";"+Row["nobatkari"].ToString() + ";" + Row["pname"].ToString())
.ToArray()))
.ToList();
now I want to count each item over date I mean that I want to know how many rows are with the same date
please help me to solve it
for example:
1 **2017-02-19** 15:12:20 1 0 1 0
1 **2017-02-19** 15:12:37 1 0 1 0
1 **2017-02-19** 15:12:41 1 0 1 0 Count:3
1 **2017-02-20** 15:14:10 1 2 1 0
1 **2017-02-20** 16:38:14 1 2 1 0
3 **2017-02-20** 16:38:19 1 2 1 0 Count:3
3 **2017-02-21** 16:39:09 1 0 1 0
3 **2017-02-21** 17:25:06 1 0 1 0
2 **2017-02-21** 18:28:50 1 0 1 0 Count:3
2 **2017-02-22** 18:29:04 1 0 1 0 Count:1
2 **2017-02-23** 18:29:17 1 0 1 0
3 **2017-02-23** 18:30:45 1 0 1 0 Count:2
2 **2017-02-24** 18:31:32 1 0 1 0
2 **2017-02-24** 18:31:47 1 0 1 0 Count:2
2 **2017-02-25** 18:32:18 1 4 1 0 Count:1
Of course I want date section not time include
var res = yourList.GroupBy(x => x.date.Date).Select(x=> new { date = x.Key, count = x.Count() });
This will create a new list containtng date and count of elements for each date.
I am using iTextSharp in my C# application. PDF reader gives error:
The document has no page root (meaning: it's an invalid PDF).
Then we again try to fetch count property using below regex:
using (StreamReader sr = new StreamReader(File.OpenRead(#"C:\test.pdf")))
{
Regex regex = new Regex(#"/Type\s*/Page[^s]");
MatchCollection matches = regex.Matches(sr.ReadToEnd());
Console.WriteLine(matches.Count);
}
But using this regex we get double count..(i.e if actual file has 6 count this regext returns count as 12)
Any solution to get page for this kind of files ?
I can not share file as it is client provided file.
On future verification on file content, i found below matches for regex:
/Type /XObject
/Type /Page
/Type /Catalog
/Type /XObject

Because of last matches it gives double count then actual.(i.e 12 count instead 6 count)
Is there any solution for solving this kind of file,as this is file specific issue not with all file.
Thanks
.NET Framework 4.6, C#.
Using nAudio to read a MIDI file to convert the below into a notation structure that shows a single column with 16th notes and multiple sustain values if the note needs to be a quarter/half/full. So the result would start to look like this to display "C6" as a quarter note:

I don't nuderstand how to read the Velocity and NoteLength properties/fields to get note duration values. Can someone point me in the right direction?

However when I run the same command using C#, I don't get any standard output, all I get is standard error. Following is my C# code
ProcessStartInfo _processStartInfo = new ProcessStartInfo();
_processStartInfo.RedirectStandardOutput = true;
_processStartInfo.RedirectStandardError = true;
_processStartInfo.UseShellExecute = false;
_processStartInfo.CreateNoWindow = true;
_processStartInfo.FileName = "curl.exe"
_processStartInfo.Arguments = "http://localhost:8081/statusstream";
_process = new Process();
_process.StartInfo = _processStartInfo;
_process.EnableRaisingEvents = true;
_process.StartInfo.RedirectStandardOutput = true;
_process.StartInfo.RedirectStandardError = true;
_process.ErrorDataReceived += _process_ErrorDataReceived;
_process.OutputDataReceived += _process_OutputDataReceived;
_process.Exited += _process_Exited;
_process.Start();
_process.BeginOutputReadLine();
_process.BeginErrorReadLine();
The following method is always being hit, but not the the one which is waiting for StandardOutput
private void _process_ErrorDataReceived(object sender, DataReceivedEventArgs e)
{
if (!string.IsNullOrEmpty(e.Data))
this.ConsoleLog = string.Format("[StdErr] {0}",e.Data);
}
Output that i get from running CURL command from C# is:

If I see the received column, its value increases from 40 to 250, that means probably something is being return from the stream.
Issuing other HTTP GET commands from CURL using C# gives proper standardoutput. But other get commands return content immediately and are not streaming continuously.
Can someone please point what I'm doing wrong.
Ok, so I'm not supposed to call cURL.exe from C# code. But is there a way where I can monitor a URL to get continuous stream of data whenever there are updates? I don't want to call HttpClient GetStringAsync in a while loop.
I have two sheets in Excel. Sheet2 contains data and I need that is on per date for 1 month, I would like to copy/paste the data on sheet1 by matching the date I put on the Blank date, example: Put Oct 1 on the date of sheet1 it will automatically copy the data of Oct 1 on sheet2. put Oct 2 copy data on Oct 2 an so on..

well, to copy certain range(with cell content, ...) you should try following, for example:
Excel.Range selCell1 = ((Excel.Worksheet)Application.ActiveSheet).Range["A1", "CA2000"];
Excel.Range selCell2 = ((Excel.Worksheet)Application.Sheets[2]).Range["A1", "CA2000"];
selCell1.Copy(selCell2);
Do you need a C# solution? Otherwise you can easily construct this type of thing directly in the excel spreadsheet:
=INDEX($11:$20,ROW(),MATCH($A$1,$11:$11,0)+COLUMN()-1)
Good Luck.
