php - phpExcel in codeigniter -

I try to get the Excel file and cover it in PDF. I get success but I do not see the data and tell me that the data can not load in PDF

Here my code: 

  // Our new PHPExcel library Load $ this- & gt; Load-> Library ('excel'); $ InputFileName = 'nameoffile'; $ Excel2 = PHPExcel_IOFactory :: createReader ('Excel5'); $ Excel2 = $ excel2- & gt; Load ($ inputfilename '.xls'); $ Excel2- & gt; SetActiveSheetIndex (0); Header ('pragma: public'); Header ('expiration: 0'); Header ('Cash-Control: Required-Modified, Post Check = 0, Pre-Check = 0'); Header ('content-type: application / force-download'); Header ('content-type: application / octet-stream'); Header ('content-type: application / download'); Header ("content-dispute: attachment; file name = to-template.pdf"); Header ('content-transfer-encoding: binary'); $ ObjWriter = PHPExcel_IOFactory :: createWriter ($ excel2, 'pdf'); $ ObjWriter- & gt; Save ('php: // output'); This is probably because  is not a PHPExcel_Writer_xls , however, A  PHPExcel_Writer_Excel5  is that you should use if you are trying to write BIFF-format  .xls  files  
 However, your code shows The file names are "case-sensitive" so that you are trying to create a PDF author, so a  PDF  author needs to specify it in the upper case  
 < Code> $ objWriter = PHPExc El_IOFactory :: createWriter ($ excel2), 'pdf');   
  Edit   
 Do not use the same spreadsheet for your reader  
  $ reader = PHPExcel_IOFactory :: createReader ('Excel5'); $ Spreadsheet = $ reader- & gt; Load ($ inputfilename '.xls'); Header ('content-type: application / pdf'); Header ('content-dispute: attachment; file name = "to-template.pdf"'); Header ('cache-control: max-age = 0'); // If you are serving in IE 9, then you may need a header for the following ('cache-control: max-age = 1'); // If you are serving IE on SSL, the header may be required for the following ('End: Mon, 26 July 1997 05:00:00 GMT'); // Date in the previous header ('Last-Modified:'. GMDET ('D, DM YH: I: S'). 'GMT'); // always modified the header ('cache-control: cache, must-revise'); // HTTP / 1.1 Header ('Prague: Public'); // http / 1.0 $ author = PHPExcel_IOFactory :: createWriter ($ spreadsheet, 'PDF'); $ Author- & gt; Save ('php: // output'); Die ();

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
