powerbuilder appeon mobile web. how to determine a url link is returning a 404 - powerbuilder

When using a picture control on a appeon mobile web, how do you determine that the picture name url is returning a 404 error, file not found error?
Example code line: p_picture.picturename = "http://myurl.org/picture.jpg"
tia

Please try the GetUrl function of the inet object. You can find the string "404 - File or directory not found" in the return content if the 404 error occurred.
Please refer to the simple PB case below for details.

Failing to post content with rebrandly links to LinkedIn

I noticed that posting to LinkedIn via API and web fails when the content has a rebrandly short link in it. I've tried other short link providers, and they all work fine.
For example, I can't post to https://www.linkedin.com/feed/ when my post contains https://rebrand.ly/ooz9t, but if I change the rebrandly link to https://rebrandly/ooz9t the post succeeds (of course, now the short link is invalid). When I try posting through LinkedIn's API, I get the following error:
(403): com.linkedin.restli.client.RestLiResponseException: Response status 403, serviceErrorMessage: Urls submitted doesn't pass ucv validation: [http://rebrand.ly/ooz9t]
Can anybody help me with decoding this LinkedIn error? Does LinkedIn not support rebrandly links?
Thanks in advance!

How to play video from remote URL in android?

I am New to android my intention is to play video using Http.
But i am getting "Http Request Failed 404" Exception when iam trying to run my application in emulator.
can any one know this error?
plz help me Thanks in advance.
404 normally means the URL cannot be found.
What is the exact URL & have you tried to play that URL in software like mplayer or VLC?
404 error means it can not find the video file on the URL that you provided.
perhaps you have given a wrong URL?

Request for Request Token from Intuit IPP gives permission denied

I am doing this on my local development site without problems. But when I try to setup a new connection to a QuickBooks file from my live site, I get a permission denied error.
Here is the error returned: "Post https://oauth.intuit.com/oauth/v1/get_request_token: permission denied"
Here are the request headers
Content-Type
application/x-www-form-urlencoded
Authorization
OAuth oauth_consumer_key="MY_KEY",
oauth_nonce="MY_NONCE",
oauth_signature="MY_SIG",
oauth_signature_method="HMAC-SHA1",
oauth_timestamp="1377287041",
oauth_version="1.0"
Here is the request body:
oauth_callback=http%3A%2F%2Fwww.intheloop-notes.com%2Fqb%2Fconnect%2Freturn%2F
---- EDIT ----
The response is nil altogether, I am getting an error from my Go code on:
response, err := client.Do(request)
Which is why I have added a couple of tags to this question (go and google-app-engine) to try and broaden my audience. I am pretty sure that the error is in the way that my OAuth library is sending the request. I am using this library: https://github.com/kurrik/oauth1a, which has been working just fine on my local development site, but gives me the "permission denied" error when I make the call from my live site. I think there is some difference in the way that the development app engine server creates the request from the way the live engine does, but I am not sure exactly what.
Any ideas?
Eureka! I figured it out! And thank you, Manas, I would not have found this solution without that last link you gave. For anyone who is wondering: I had to create a custom http.Client using the appengine.urlfetch library. Once I figured that out, the solution was simple, I just had to change one line of code that created the client into this:
client := urlfetch.Client(appengine.NewContext(r))
Problem solved!
