Here is my code for initiating download
System.Web.HttpContext.Current.Response.ClearContent();
System.Web.HttpContext.Current.Response.Charset = "utf-8";
System.Web.HttpContext.Current.Response.HeaderEncoding = UnicodeEncoding.UTF8;
System.Web.HttpContext.Current.Response.ContentEncoding = UnicodeEncoding.UTF8;
//System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
System.Web.HttpContext.Current.Response.AddHeader("Content-Type", "text/csv");
System.Web.HttpContext.Current.Response.AddHeader("Cache-Control", "max-age=0");
System.Web.HttpContext.Current.Response.AddHeader("Accept-Ranges", "none");
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment" + "; filename=Data.csv");
System.Web.HttpContext.Current.Response.BinaryWrite(buffer);
System.Web.HttpContext.Current.ApplicationInstance.CompleteRequest();
System.Web.HttpContext.Current.Response.Flush();
System.Web.HttpContext.Current.Response.Close();
args.AbortPipeline();
the out csv file contains like this at the place of some arabic letters
Data
99999;Arabic: ?????????????? ?????????????? al-abj;jkj;biluruya#mswork.ru;
I dont know why the UTF-8 encoding is not working here or is my download code wrong . could some one pls explain me the issue here ?
Thanks

I am using jsPDF to create a pdf file from a webpage. I like to add a text but if use ä ö ü it won't be rendered correctly.
I tried to add Unicode characters to my pdf using the documentation, but the docs they have added for the library related to the Unicode part doesn't include any examples. It would be great if you could provide an example.
This is my code:
function doDocData(doc) {
var number_of_pages = doc.internal.getNumberOfPages()
var pdf_pages = doc.internal.pages
doc.setFontStyle('normal');//optional
for (var i = 1; i < pdf_pages.length; i++) {
doc.setPage(i)
var strl = 'I like to add Ä Ü Ö';
doc.setFontSize(10);// optional
doc.text(strl, 20, doc.internal.pageSize.height - 10);//key is the interal pageSize
var str = 'Seite ' + i + ' von ' + number_of_pages;
doc.setFontSize(10);// optional
doc.text(str, doc.internal.pageSize.width - 80, doc.internal.pageSize.height - 10);//key is the interal pageSize
}
}
For utf-8 encoded Characters like Ä, Ö, Ü you need to include a font, that is utf-8 encoded (like it is stated in the Documentary: Use of Unicode Characters / UTF-8) since jsPDF by default contains only ASCII font.
A font like this (ARIAL utf-8 ATTENTION: opens download of arialuni.ttf) can be converted by jsPDF own fontconverter.
You can find a code example how to include the converted font here: setFont in jsPDF
Hi I want to read the hdf5 file data as it is written
But when I read it with the following code I get the following output
COde
hf = h5py.File('Json.h5', 'r')
data_read = hf.get("BinaryData_metadata")
rmdwrite = open("Test.json", "w")
rmdwrite.write(str(np.array(data_read)))
rmdwrite.close()
hf.close()
Output
[b'{\n\t"TestReport": {\n\t\t"TestName": "XYZ",\n\t\t"Description"................
How to get the exact output with the same formatting in my output file?
When I print with this
Data_arr = str(np.array(data_read))
Data_arr = repr(Data_arr)
I get
'[b\'{\\n\\t"TestReport": {\\n\\t\\t"Te................
OKey this is how I am writing the data via C++
DataSpace dataspace(1, dimsf); //Creating Dataspace
StrType datatype(PredType::C_S1); //Creating Datatype of type char
datatype.setOrder(order); //Data Store Order
datatype.setSize(file_datastring.length()); //Datalength
datatype.setCset(H5T_CSET_UTF8);
DataSet dataset = Hdf5::fileObject.createDataSet(WriteDataSet, datatype, dataspace); //Create dataset
dataset.write(file_datastring, datatype); //Write to dataset
is there something here which is appending that extra \
The solution which I found was
hf = h5py.File(H5FileName, 'r')
FileObj = open(OutFileName, "w")
hf.get(H5DataSetName).value.tofile(FileObj)
FileObj.close()
hf.close()
This works perfectly

I encountered a problem with setting the page header text containing ampersand like ‘a&b’. The text after ‘&’ disappears in the pdf maybe because it is the reserved key in Aspose. My code looks like this:
PageSetup pageSetup = workbook.getWorksheets().get(worksheetName).getPageSetup();
//calling the function
setHeaderFooter(pageSetup, parameters, criteria)
//function for setting header and footer
def setHeaderFooter(PageSetup pageSetup, parameters, criteria = [:])
{
def selectedLoa=getSelectedLoa(parameters)
if(selectedLoa.length()>110){
String firstLine = selectedLoa.substring(0,110);
String secondLine = selectedLoa.substring(110);
if(secondLine.length()>120){
secondLine = secondLine.substring(0,122)+"...."
}
selectedLoa = firstLine+"\n"+secondLine.trim();
}
def periodInfo=getPeriodInfo(parameters, criteria)
def reportingInfo=periodInfo[0]
def comparisonInfo=periodInfo[1]
def benchmarkName=getBenchmark(parameters)
def isNonComparison = criteria.isNonComparison?
criteria.isNonComparison:false
def footerInfo="&BReporting Period:&B " + reportingInfo+"\n"
if (comparisonInfo && !isNonComparison){
footerInfo=footerInfo+"&BComparison Period:&B " +comparisonInfo+"\n"
}
if (benchmarkName){
footerInfo+="&BBenchmark:&B "+benchmarkName
}
//where I encounterd the issue,selectedLoa contains string with ampersand
pageSetup.setHeader(0, pageSetup.getHeader(0) + "\n&\"Lucida Sans,Regular\"&8&K02-074&BPopulation:&B "+selectedLoa)
//Insertion of footer
pageSetup.setFooter(0,"&\"Lucida Sans,Regular\"&8&K02-074"+footerInfo)
def downloadDate = new Date().format("MMMM dd, yyyy")
pageSetup.setFooter(2,"&\"Lucida Sans,Regular\"&8&K02-074" + downloadDate)
//Insertion of logo
try{
def bucketName = parameters.containsKey('printedRLBucketName')?parameters.get('printedRLBucketName'):null
def filePath = parameters.containsKey('printedReportLogo')?parameters.get('printedReportLogo'): null
// Declaring a byte array
byte[] binaryData
if(!filePath || filePath.contains("null") || filePath.endsWith("null")){
filePath = root+"/images/defaultExportLogo.png"
InputStream is = new FileInputStream(new File(filePath))
binaryData = is.getBytes()
}else {
AmazonS3Client s3client = amazonClientService.getAmazonS3Client()
S3Object object = s3client.getObject(bucketName, filePath)
// Getting the bytes out of input stream of S3 object
binaryData = object.getObjectContent().getBytes()
}
// Setting the logo/picture in the right section (2) of the page header
pageSetup.setHeaderPicture(2, binaryData);
// Setting the script for the logo/picture
pageSetup.setHeader(2, "&G");
// Scaling the picture to correct size
Picture pic = pageSetup.getPicture(true, 2);
pic.setLockAspectRatio(true)
pic.setRelativeToOriginalPictureSize(true)
pic.setHeight(35)
pic.setWidth(Math.abs(pic.getWidth() * (pic.getHeightScale() / 100)).intValue());
}catch (Exception e){
e.printStackTrace()
}
}
In this case, I get only ‘a’ in the pdf header all other text after ampersand gets disappeared. Please suggest me with a solution for this. I am using aspose 18.2
We have added header on a PDF page with below code snippet but we did not notice any problem when ampersand sign is included in header text.
// open document
Document document = new Document(dataDir + "input.pdf");
// create text stamp
TextStamp textStamp = new TextStamp("a&bcdefg");
// set properties of the stamp
textStamp.setTopMargin(10);
textStamp.setHorizontalAlignment(HorizontalAlignment.Center);
textStamp.setVerticalAlignment(VerticalAlignment.Top);
// set text properties
textStamp.getTextState().setFont(new FontRepository().findFont("Arial"));
textStamp.getTextState().setFontSize(14.0F);
textStamp.getTextState().setFontStyle(FontStyles.Bold);
textStamp.getTextState().setFontStyle(FontStyles.Italic);
textStamp.getTextState().setForegroundColor(Color.getGreen());
// iterate through all pages of PDF file
for (int Page_counter = 1; Page_counter <= document.getPages().size(); Page_counter++) {
// add stamp to all pages of PDF file
document.getPages().get_Item(Page_counter).addStamp(textStamp);
}
// save output document
document.save(dataDir + "TextStamp_18.8.pdf");
Please ensure using Aspose.PDF for Java 18.8 in your environment. For further information on adding page header, you may visit Add Text Stamp in the Header or Footer section.
In case you face any problem while adding header, then please share your code snippet and generated PDF document with us via Google Drive, Dropbox etc. so that we may investigate it to help you out.
PS: I work with Aspose as Developer Evangelist.
Well, yes, "&" is a reserved word when inserting headers/footers in MS Excel spreadsheet via Aspose.Cells APIs. To cope with your issue, you got to place another ampersand to paste the "& (ampersand)" in the header string. See the sample code for your reference:
e.g
Sample code:
Workbook wb = new Workbook();
Worksheet ws = wb.getWorksheets().get(0);
ws.getCells().get("A1").putValue("testin..");
String headerText="a&&bcdefg";
PageSetup pageSetup = ws.getPageSetup();
pageSetup.setHeader(0, headerText);
wb.save("f:\\files\\out1.xlsx");
wb.save("f:\\files\\out2.pdf");
Hope this helps a bit.

Can someone please tell me how to create a file and make it available for download via browser button?
I have read about FileWriter but not found any proper example how to use it
and I found a post How to use the dart:html library to write html files?
but the answer just refers to html5lib which just answers how to parse a String to HTML but not how to save as a file.
help appreciated. Am I missing something or there is no example for that usecase??
Personally, I use a combination of Blob, Url.createObjectUrlFromBlob And AnchorElement (with download and href properties) to create a downloadable file.
Very simple example:
// Assuming your HTML has an empty anchor with ID 'myLink'
var link = querySelector('a#myLink') as AnchorElement;
var myData = [ "Line 1\n", "Line 2\n", "Line 3\n"];
// Plain text type, 'native' line endings
var blob = new Blob(myData, 'text/plain', 'native');
link.download = "file-name-to-save.txt";
link.href = Url.createObjectUrlFromBlob(blob).toString();
link.text = "Download Now!";
As alluded to by Günter Zöchbauer's comment, an alternative to using Blobs is to base64-encode the data and generate a data URL yourself (at least for file sizes that are well within the data URL limits of most browsers). For example:
import 'dart:html';
Uint8List generateFileContents() { ... }
void main() {
var bytes = generateFileContents();
(querySelector('#download-link') as AnchorElement)
..text = 'Download File'
..href = UriData.fromBytes(bytes).toString()
..download = 'filename';
}
Also note that if you do want to use a Blob and want to write binary data from a Uint8List, you are expected to use Blob([bytes], ...) and not Blob(bytes, ...). For example:
var bytes = generateFileContents();
var blob = Blob([bytes], 'application/octet-stream');
(querySelector('#download-link') as AnchorElement)
..text = 'Download File'
..href = Url.createObjectUrlFromBlob(blob)
..download = 'filename';
I browsed around for a solution and I am sure it's a simple question but still not sure how to do that. So, I have a string that contains many words and some times it has links in it. For example:
I like the website http://somesitehere.com/somepage.html and I suggest you try it too.
I want to display the string in my view and have all links automatically converted to URLs.
#Model.MyText
Even StackOverflow gets it.
#Hunter is right.
In addition i found complete implementation in C#: http://weblogs.asp.net/farazshahkhan/archive/2008/08/09/regex-to-find-url-within-text-and-make-them-as-link.aspx.
In case original link goes down
VB.Net implementation
Protected Function MakeLink(ByVal txt As String) As String
Dim regx As New Regex("http://([\w+?\.\w+])+([a-zA-Z0-9\~\!\#\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)?", RegexOptions.IgnoreCase)
Dim mactches As MatchCollection = regx.Matches(txt)
For Each match As Match In mactches
txt = txt.Replace(match.Value, "<a href='" & match.Value & "'>" & match.Value & "</a>")
Next
Return txt
End Function
C#.Net implementation
protected string MakeLink(string txt)
{
Regex regx = new Regex("http://([\\w+?\\.\\w+])+([a-zA-Z0-9\\~\\!\\#\\#\\$\\%\\^\\&\\*\\(\\)_\\-\\=\\+\\\\\\/\\?\\.\\:\\;\\'\\,]*)?", RegexOptions.IgnoreCase);
MatchCollection mactches = regx.Matches(txt);
foreach (Match match in mactches) {
txt = txt.Replace(match.Value, "<a href='" + match.Value + "'>" + match.Value + "</a>");
}
return txt;
}
One way to do that would be to do a Regular Expression match on a chunk of text and replace that url string with an anchor tag.
Another regex that can be used with KvanTTT answer, and has the added benefit of accepting https urls
https?://([\w+?.\w+])+([a-zA-Z0-9\~!\##\$\%\^\&*()_-\=+\/\?.:\;\'\,]*)?
.net string representation:
"https?://([\\w+?\\.\\w+])+([a-zA-Z0-9\\~\\!\\#\\#\\$\\%\\^\\&\\*\\(\\)_\\-\\=\\+\\\\\\/\\?\\.\\:\\;\\'\\,]*)?"
