php - Download Excel file using PHPExcel -

-

I am trying to download the excel file using PHPExcel, it seems that this excel file is well downloaded But the data in the Excel file is everything Crap .. What I do not expect is that I have passed very basic ways to test my Excel sheet data output

here the code I'am Trying 

  else if ($ request- & gt; p ['type'] == 'excel') {$ report_type_name = "Graph all Report "; $ ExcelReport = New ExcelApExport ($ classes, $ group_definition, $ questions, $ sample_corrections); $ ObjPHPExcel = $ ExcelReport- & gt; Export ($ set, $ disp_filter); Header ('content-type: application / vnd.ms-excel'); Header ("content-dispute: attachment;". Escape_for_content_disposition ("{$ report_name} - {$ report_type_name} -" .date ("Y-M-D.H."). ".xls")); Header ('cache-control: max-age = 0'); $ ObjWriter = PHPExcel_IOFactory :: createWriter ($ objPHPExcel, 'Excel 2007'); $ ObjWriter- & gt; Save ('php: // output'); Go out; } Here I also make an object here and call phpexcel methods here  
  Public function export ($ set, $ disp_filter) {$ objPHPExcel = New PHPExcel (); $ ObjPHPExcel- & gt; GetProperties () - & gt; Setitle ("official excel test document"); $ ObjPHPExcel- & gt; GetProperties () - & gt; Set form ("test document"); $ ObjPHPExcel- & gt; GetProperties () - & gt; Set descriptio ("Test document for XLS, generated by using PHP classes."); // Echo date ('H: I: S'). "Add some data \ n"; $ ObjPHPExcel- & gt; SetActiveSheetIndex (0); $ ObjPHPExcel- & gt; GetActiveSheet () - & gt; Setcell value ('A1', 'Hello'); $ ObjPHPExcel- & gt; GetActiveSheet () - & gt; Setel Value ('B2', 'World!'); $ ObjPHPExcel- & gt; GetActiveSheet () - & gt; Setale value ('c1', 'hello'); $ ObjPHPExcel- & gt; GetActiveSheet () - & gt; Satell Value ('D2', 'world!'); Return $ objPHPExcel; }  
 
 This is what I get in my downloaded Excel file  
 
 Could you please suggest me why this nonsense data is displayed in my file instead of expected data in advance thanks in advance

$ objWriter = PHPExcel_IOFactory :: createWriter ($ objPHPExcel, 'Excel2007'); This author is for

.xls x files. (See:

Then the correct header will be: 

  // Redirection for client's Web browser (Excel 2007) Header ('Content-Type: App / vnd .openxmlformats-officedocument.spreadsheetml.sheet '); Header ("content-dispute: attachment;". Escape_for_content_disposition ("{$ report_name} - {$ report_type_name} -". Date ("Y-M-DHHI"). ".xlsx")); //.xlsX!

Author of old .xls-files:

$ objWriter = PHPExcel_IOFactory :: createWriter ($ objPHPExcel, 'Excel5');

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
