404 Error when exporting Excel from ActiveReports 8 -

-

I am struggling with this and for two weeks, most of the time for that time my responses to the support issue. That is what I would expect that will help the next person who is moving forward on this issue. I am going to throw a lot of unnecessary expansion to increase the barriers of the next man.

I am working on an MVC 5 site and an ILISIL-bound code-based section report using the ActiveReports 8 HTML 5 viewer. I have enabled PhD, Word and Excel Exports using the available export parameters for the GrapeptectivePortports. The Viewer Javascript function renders properly on the Viewer page, and makes the requisite calls to ActiveReports. ReportSerice.asmx, which provides the information necessary to present the report, from which the URL is included for streaming the data. The report displays in the viewer just fine. So far so good.

On my development machine, I can export in PDF, Word and Excel. When the test server is deployed, however, the Excel export stops working, and the browser only shows a file that attempts to save a file named ActiveReports.ar8? After digging with Blahblahblah Fiddler, I decided that this is almost the same as the URL returned to the URL for the report service, except for some parameters like "command = export" and "export format = xls".

Saving this "file" is in a 0-byte file called ActiveReports.xls. I remove this important DLL like GrapeCity.ActiveReports.Export.Pdf for other export types and then export PDFs For example, I can ask for. It appears that ActiveReports (at least as version 8.1.414.0) swallows some server-side errors, such as missing DLL, and returns a 404 error code to the customer. I think a 500 error would be better for the general 404 with details of what is missing.

I must believe that there is something wrong with the test server since I have all the active ActiveDeports DLL on the local "set", and I can see that they were all successfully deployed to the test server The missing piece should be present in the GAC of my local machine, but not on the server.

What is missing on the server that is stopping Excel from completing the export?

The missing piece of the puzzle is DocumentFormat.OpenXml.dll, which is a copy of "C: \ Program Files (X86) \ Common Files can be found in the \ ComponentOne \ ActiveReports 8 "folder ironically, it is described above all of the whole grapes whistle. Active Reports assembly, but it is used for other denominations without any indication, you can easily see it properly as I did, assuming that the dependency of something else in that folder was the license generator

Adding context to the Web document in DocumentFormal.OpenXml.dll, and setting the copy locale to the correct ensures that DLL is deployed with everyone else. My Excel export works just fine.

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...
