asp.net - Download a file from a WebForm using C# -

-

I need to download a file from a website (not written by me) I have a valid Username / password, and I can do it manually But I want to make it in an automated process (C #) to be downloaded from time to time.

Manually need to login to me, browse to the download page, select some combo box, and then click "Download". This link does a postback and returns the requested file.

I think the webclient me Download file should be used, but I can not understand how to pass all the required data and request postback properly. / P>

Is this another website API?

Otherwise, all you need to do is submit a web request, all the details in the description format, then read the feedback, then automatically fill the second form for "Check some combo box", and then finally file Read that response.

Alternatively, there is a browser emulation software, such as Selenium, which is used for website testing. You can install a test / script over there, which will do all of the above for you. I'm not sure how it handles downloaded files.

If you want to route 1, then be prepared to change your schedule every time other websites change. And if they add a captcha, then you get very bad.

Easily, will the password stored in any web browser save you from trouble?

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...
