Here goes the path I follow.
1. User enters text in html editor, tiny mce edtitor.
2. that text is uploaded to Server side MVC controller
3. Controller use following line to write that HTML content (string) to a temp location on server
new MemoryStream(Encoding.Unicode.GetBytes(HtmlContent))
4. That file in temp location (in another step) is then used to get a byte[] of the contents
5. In the last step byte[] is send via stored procedure to database to a column field of type varbinary.
Now the problem is that when I read that varbinary back to byte[] and send it to browser using the following line of MVC with MIME type text/HTML.
File(attachmentFile.BinaryData, mimeType, pFileName);
The file downloads and opens correctly in both IE and Firefox but not in chrome. I don't know what the issue is with chrome

I need some help with PHPEXCEL library, everything works great, I'm successfully extracting my SQL query to excel5 file, I need to give this file to transport company in order to auto collect informations about packages, unfotunately the generated excel file has some ascii characters between each letter of the cell text, and when the excel file is imported you need to manually delete these charaters.
If I open the excel file, everything is fine I see: COMPANY NAME, If I open the excel file with notepad++, I see the cell values this way: C(NUL)O(NUL)M(NUL)P(NUL)A(NUL)N(NUL)Y N(NUL)A(NUL)M(NUL)E
If I open again the file with excel and save, then reopen with notepad++ I see COMPANY NAME.
So I do not understan why every time I create an excel file using PHPEXCEL my every letter of all words are filled with (nul) every letter.
So how do I prevent the generated excel file to include (nul) between every word????
Also if you open the original excel file generated from PHPExcel samples are also filled with (nul) and if you open and save it, the (nul) is gone.
Any help would be appreciated, thanks.
what is the (nul) ??? 0x00??? char(0)???
ok, here is the example:
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');
if (PHP_SAPI == 'cli')
die('Disponibile solo su browser');
require_once dirname(__FILE__) . '/Classes/PHPExcel.php';
$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setCreator("Solidus")
->setLastModifiedBy("Solidus")
->setTitle("Import web")
->setSubject("Import File")
->setDescription("n.a")
->setKeywords("n.a")
->setCategory("n.a");
$objPHPExcel->setActiveSheetIndex(0)
->setCellValueExplicit("A1", "COMPANY")
->setCellValue('A2', 'SAMSUNG');
$objPHPExcel->getActiveSheet()->setTitle('DDT');
$objPHPExcel->setActiveSheetIndex(0);
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="TEST.xls"');
header('Cache-Control: max-age=0');
header('Cache-Control: max-age=1');
header('Cache-Control: private',false);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
ob_end_clean();
$objWriter->save('php://output');
As you can see from this little example, this scripts creates a file excel5 with 2 cells, A1 = COMPANY, A2 = SAMSUNG
when I send this file to the transport company, they import the file into their system, but as you can see from the picture, there is an weird character between each letter.
so I noticed every time I open the generated Excel5 with notepad++ file I get:
S(nul)A(nul)M(nul)S(nul)U(nul)N(nul)G
If I save the save with excel and then open it again with notepad++ I get:
SAMSUNG
and this file is ok for the transport company
so my question is, how should I avoid the file generated to contain thi '(nul) charachter between each letter????
some help?
weird characters
SAMSUNG
I found the soluion by myself, I explain just in case anyone has also this problem:
there is not way to change the way the excelfile is encoded by PHPEXCEL
so I figured out the problem was reading the file, I did some simulations and reproduce the problem, every time a read the file and put the result into inputs a get weird characters:
C�O�M�P�A�N�Y�
If I set the output enconding enconding as follows:
$excel->setOutputEncoding('UTF-8');
the file loads fine, so the problem was not creating the excel file, but reading the excel file.
If I print the variable with ECHO I get: "COMPANY",
if I put the variable on input as value I get: "C�O�M�P�A�N�Y�"
setting the output solves the problem, but I would like to know why the difference when I put the variable on input as value, thanks
I am facing an issue while exporting japanese text in CSV format. Junk characters are being exported instead of original japanese text. I am using .NET MVC FileStreamResult to export records in Csv file and used encoding format as UTF8 (I have also used some other encoding format, but no luck). I debugged my code and able to convert string from memory stream and vice versa and able to see original japanese text being exported. Once exporting completed, I opened the CSV file, but only able to see junk character instead of expected text. If I open the CSV file in NotePad ( Opening the csv file in Notepad is NOT my requirement. I am referring Notepad only to verify whether i am able to see Japanese translated language ), then i can see the expected japanese text. It would be really helpful if someone please help me find root cause of this issue and provide a resolution.
Ex. 東京都品川区大崎 gets written as æ±äº¬éƒ½å“å·åŒºå¤§å´Ž
Note: I can see expected japanese text is exported properly if I opened the sample .CSV file using LibreOffice Calc, Linux default gEdit. But the issue is with opening this csv file using MS Office.
Please find the below attached code -
Controller/Action to execute while clicking on export to Csv button
================================================================================
[HttpPost]
[ValidateInput(false)]
public FileStreamResult SaveCustomerInfo()
{
return ExportToCsv();
}
================================================================================
private static FileStreamResult ExportToCsv()
{
var exportedData = new StringBuilder();
exportedData
.AppendLine("実行日,口座番号,支店番号,アカウント名,支店名,の/受益秩序,ステートメント日,入力日,お問い合わせ番号, ,Date Range")
.Append(
"CS0001,Demo FName,Demo LName,8/20/2015,\"Demo User Address\",City,Country,08830,0123456789,15813,Absolute from 8/20/2015 to 8/22/2015");
var stream = PrintingHelper.StringToMemoryStream(Encoding.UTF8, exportedData.ToString());
var fileStreamResult = new FileStreamResult(stream, "text/csv")
{
FileDownloadName =
new StringBuilder("TestExportedFileInCsv")
.Append(".csv").ToString()
};
return fileStreamResult;
}
It sound as though you haven't installed the language pack for MS Office on the machine that you are trying to open the csv on.
I am facing problem when passing value for url through data field.
I am passing value in goto url like this
="javascript:void(window.open('file:" &Fields!url.Value &"','_blank'))"
url value = /servername/foldername/FormuláriodeCalibração.xls
After report deployed and opened in internet explorer and clicked on the url. It is changing the url like this
/servername/foldername/FormuláriodeCalibração.xls
because of which I am unable to open the file.
Please help me in this.
Finally we come up with a solution of replacing non ASCII characters of Portuguese with HTML ASCII Codes.
For e.g. this is the actual file name of the attachment
TE-5180FormuláriodeCalibração(modelo)1271440308393(2)1338379011084.xls
We replaced the Portuguese characters with HTML ASCII Codes.
TE-5180FormuláriodeCalibração(modelo)1271440308393(2)1338379011084.xls
After these changes the above modified URL is passed in the place of actual URL and when it hits the server it was decoded properly and worked as expected.
I am able to use TCPDF and generate a PDF in the browser using JQuery/JavaScript:
window.open("", "pdfWindow",scrollbars=yes, resizable=yes, top=500, left=500, width=400, height=400");
$("#" + formID).attr('action','tcpdf/example/genReport.pdf').attr('target','pdfWindow');
In genReport.pdf, I am using $pdf->Output('genReport.pdf', 'I');
When genReport.pdf is generated, it appears in a new tab with the standard browser settings. I wanted to know if there is a way to have the generated PDF automatically display in Acrobat Reader?
Any help will be greatly appreciated.
According to the documentation of the output() function, the second parameter can be one of those:
I: send the file inline to the browser (default). The plug-in is used if available. The name given by name is used when one selects
the "Save as" option on the link generating the PDF.
D: send to the browser and force a file download with the name given by name.
F: save to a local server file with the name given by name.
S: return the document as a string (name is ignored).
FI: equivalent to F + I option
FD: equivalent to F + D option
E: return the document as base64 mime multi-part email attachment (RFC 2045)
So I'd suggest using $pdf->Output('genReport.pdf', 'D'); this will open the download dialog and the user can choose to either open or download the file.
ASP.NET has four different types of file results:
FileContentResult: Sends the contents of a binary file to the response.
FilePathResult: Sends the contents of a file to the response
FileResult: Returns binary output to write to the response
FileStreamResult: Sends binary content to the response by using a Stream instance
Those descriptions are take from MSDN and with the exception of the FileStreamResult the first three sound identical. So what is the difference between them?
FileResult is an abstract base class for all the others.
FileContentResult - you use it when you have a byte array you would like to return as a file
FilePathResult - when you have a file on disk and would like to return its content (you give a path)
FileStreamResult - you have a stream open, you want to return its content as a file
However, you'll rarely have to use these classes - you can just use one of Controller.File overloads and let ASP.NET MVC do the magic for you.
Great question...and deserves more details. I find myself here as a result of an interesting situation. We were delivering some pdf attachments via the MVC3/C# environment. Our code got released and we started getting some responses from our clients that the downloads were behaving strangely when they were using Chrome and the file type was being converted over to 'pdf-, attachment.pdf-, attachment'. Yup...you got it...the whole thing. So, one could rewrite it to just be 'pdf' and the file would still save intact, but what a mess!
So, to describe the initial situation, we were setting the 'Content-Disposition' header then returning a FileContentResult...
var cd = new System.Net.Mime.ContentDisposition
{
FileName = result.Attachment.FileName,
Inline = false
};
Response.AppendHeader("Content-Disposition", cd.ToString());
return File(result.Attachment.Data, MimeExtensionHelper.GetMimeType(result.Attachment.FileName), result.Attachment.FileName);
Seemed good. Worked fine in IE. So I did some research and tried implementing FileStreamResult instead (keeping the Content-Disposition setter):
MemoryStream dataStream = new MemoryStream();
dataStream.Write(result.Attachment.Data, 0, result.Attachment.Data.Length);
dataStream.Position = 0;
return new FileStreamResult(dataStream, MimeExtensionHelper.GetMimeType(result.Attachment.FileName));
It fixed the issue in Chrome! Hmmm...but why in the heck should I have to take my perfectly good byte array and stream it and then return it via this to get the file name to work right?
Then came the Fiddler.
With FileContentResult, I got 2 Content-Dispositions in the header.
With FileStreamResult, I got 1.
FileContentResult appends a Content-Disposition header when providing the File Name and Chrome considers multiples of this header as an error.
Odd reaction...but definitely one that's good to know.
