"How can I send an email containing a link with parameter in C#?",
"I'm new in asp.net. I'm building a web-based application with C#, and I thought a lot about how to authenticate the user by his ID using the email.\n\nI searched about it and I tried this code but it didn't worked because it sends a page rather than link with ID.\n\n string URI = \"http://localhost:49496/Activated.aspx\";\n string myParameters = \"param1=\"+id.Text;\n string HtmlResult = \"\";\n using (WebClient wc = new WebClient())\n {\n wc.Headers[HttpRequestHeader.ContentType] = \"application/x-www-form-urlencoded\";\n HtmlResult = wc.UploadString(URI, myParameters);\n }\n\n MailMessage o = new MailMessage(\"[email protected]\", EMPemail, \"KAUH Account Activation\", \"Hello, \" + name + \"<br /> Your KAUH Account about to activate click the link below to complete the activation process <br />\" + HtmlResult);\n\n NetworkCredential netCred = new NetworkCredential(\"[email protected]\", \"______\");\n SmtpClient smtpobj = new SmtpClient(\"smtp.live.com\", 587);\n smtpobj.EnableSsl = true;\n o.IsBodyHtml = true;\n smtpobj.Credentials = netCred;\n smtpobj.Send(o);\n\n\nI need the ID in the activation page to change the \"Activated\" column from NO to YES.\n\nNow my question: is the idea to authenticate the user by sending the ID secure?if it is,How can I perform it?"

"MSComm and use of DLL to upload data VB6",
"I have a VB6 script that creates a MSComm with my device, once communication is create I go and upload a file to the device via DLL file that is included within VB6 script\n\nThe problem that I am facing is that my VB6 somehow hijacking device and I am unable to upload a file. Rather than taking 1 minute to upload a file application takes forever.\n\nI have tried following, after communication was created and MSComm1.OpenPort = True to set MSComm1.OpenPort = False but communication is still hijacked, so I need re plug my device into USB port and still nothing works (however sometimes it did work for an unknown reason, but i did have to wait a while)\n\nHowever, when I trigger file uplaod without VB6 script creating MSComm communication with device my file is uploaded successfully. \n\nI presume that this is something to do with MSComm and I presume that I need to shut it down somehow??\n\nI need to have MSComm initially because I want to fetch some data about my device.\n\n\n\nI run a command that finds a port number that I can use within VB6 after that i run MSComm.PortOpen = false; afterwards I put in file location and port number into function from DLL and run command. \n\nOn the initial run i receive an error that device is not connected, so i reconnect device, but on the second run everything seems to work except i have to wait and nothing happens. when i run DLL on its own process returns success in under 1 minutes\n\nMy settings for MS Comm within VB6\n\nDTREnable = True\nEOFEnable = False\nHandshaking = 0\nInBufferSize = 3200\nInputLen = 0\nInputMode = 0\nLeft = 6120\nOutBufferSize = 0\nRThreshold = 0\nRTSenable = False\nSettings = 2400,n,8,2\nSThreshold = 0"

"jQueryMobile running on Android / PhoneGap refuses .load / .ajax",
"I really hate asking questions that I feel were asked a thousand times before. This is one of those questions I feel others must have encountered, but having searched stack overflow, none of the supposed solutions work for me so I must be doing something wrong.....\n\nI have an extremely simple app setup. index.htm, and terms.htm. There is some textual data in test.htm. I set both $.support.cors = true; and $.mobile.allowCrossDomainPages = true; at the appropriate time after stuff has loaded.\n\nAt first I tried loading terms.htm's data into an element within index using $('#elementid').load('terms.htm'); (both test and index are in the same root /assets/www/ directory, and my webview loads index oncreate) but absolutely nothing was happening. So I opted to try .ajax so that I could at least get an error message, and all I get is 'error'. Surely, it is possible to load local textual assets with JQ on DroidGap?\n\n$('#header').load('terms.htm');\n$.ajax({\n type:\"GET\",\n timeout:10000,\n async: false,\n url: \"terms.htm\",\n success: function(data) {\n $('#header').html(data);\n },\n error: function(xhr,msg){\n alert( msg);\n }\n});"

"Javascript: How exactly do network IOs impact the execution?",
"Let's consider a Javascript web app that opened a network data channel with another peer. Now, let our app send 10 (relatively large) messages:\n\nfor (let i = 0; i < 10; i++) {\n otherPeer.channel.send(message[i])\n}\n\n\nFrom my understanding of the Javascript event loop, this will not block the code execution but will just queue some IO tasks. But intuitively, those messages will take some time to be sent, probably some time relative to the available upload capacity. \n\nSo which component will be responsible to buffer and spend the time to send these messages? Will it be in a completely separate thread, or process, or will it also affect and delay the Javascript Event queue? Even if the messages are really big and the network slow?\n\nWhat happens (in term of CPU usage and execution threads) if instead of sending 10 messages, I'd send thousands of them?\nWhat should the Javascript app do to avoid overwhelming the network?\n\nI am interested in this because I'm trying to build a simulated/virtualized environment for my Javascript app. In order to run relevant simulations, I need to virtualize the network channels of the running agents and thus, I need to understand precisely how sending messages through the network will impact the execution of the agent."

"When a notification email should be sent?",
"I have a number of action a user can preform in a social network website, like adding friends following people and such.\n\nNow these actions are done by Ajax, and the user could easily undo them(when say following someone, the follow link is turned into unfollow and clicking it again -of course- results in unfollowing the user, and it -the link- turning back into follow).\n\nWhen these actions occur, the user (being followed) is notified by via email. and the code that sends the email is run in the same ajax call.\nThat results in two problems, one is that the email is sent even if the user decides to unfollow the other person at once. And two, multiple emails are sent if the user hits the follow/unfollow link multiple times.\n\nI thought of using a session variable to store users'actions and then at \"some point\" check on that variable and preform accordingly. My struggle is in finding that \"some point\", thought of when the user logs out, but I can't guarantee that the user will actually log out.\n\nany suggestions?"

"Unity3d + WebGL = Cross-Origin Request Blocked",
"I was wondering if anyone could briefly explain how you get the REST api to function with Unity3D project built to WebGL platform. I just started changing my project over today thinking I could use REST to get around Parse's use of threading in a WebGL build I need to make. I promptly ran into the CORS problem though and not being familiar with it, I am unsure how to go about fixing the issue.\n\nCurrently I make use of the WWW class to send the request from within Unity.\n\nAn Example of \"Logging In\" a user would be:\n\n WWWForm form = new WWWForm();\n\n var headers = form.headers;\n headers[\"Method\"] = \"GET\";\n headers[\"X-Parse-Application-Id\"] = AppID;\n headers[\"X-Parse-REST-API-Key\"] = RestID;\n headers[\"X-Parse-Revocable-Session\"] = \"1\";\n headers[\"Content-Type\"] = \"application/json\";\n\n WWW www = new WWW(\"https://api.parse.com/1/login?username=\"+name+\"&password=\"+password, null, headers);\n\n\nThis works fine in the Editor but after building to WEBGL and uploading to my Host at Parse the following happens...\n\nI receive the following error in FireFox:\n\nCross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.parse.com/1/login?username=jleslie5159&password=Osulator5159!. This can be fixed by moving the resource to the same domain or enabling CORS.\n\n\nAnd something similar in Chrome..."

For the third one, \"Medicago truncatula\" is in an \"em\" HTML tag, so I suspect that this is why my scraper cannot scrape it. \n\nThe only alternative solution I've thought of is making my \"soup.findAll\" more specific, but that didn't end up helping me. I tried:\n\nfor items in soup.findAll('div', {'class': 'title'}):\n title = items.string\n if title is None:\n for other in soup.findAll('a', {'class': 'view'}):\n title = other.string\n\n\nBut sadly, this didn't work...

My chrome extension is present as a client in that list, but it's client_id is different.\n\nThe error I keep getting on the server side:\n\nWARNING 2016-04-22 03:01:35,068 users_id_token.py:372] Oauth token doesn't include an email address.\n\n\nCan anyone please give me some pointers to try?

"How to call JavaScript after PrimeFaces DataTable row click",
"I wanted to use the features from PrimeFaces DataTable so I've implemented the framework and rebuilt my current table (built with JSF) with the DataTable. Now I have a problem in that I don't know how I can call a JS function on row click. \n\nThis was my previous implementation:\n\nonclick=\"onRowClick(this, event)\"\n\n\nWith a JSF component it was possible to detect a row click. Now I want to implement this with PrimeFaces to detect the exactly the same row click in the DataTable. \n\nIs there any simple way to deal with this? onclick is not available for this PrimeFaces component so I can't just copy this."

"Facebook extended access token doesn't work - but everything seems to be fine (?)",
"I try to get 60 days facebook access token from server side request. After user is loged in I check access token through getAccessToken() function from Facebook SDK and after that I use getExtendedAccessToken() which I found somewhere here: How to extend access token validity since offline_access deprecation to ask for 60 days access token:\n\n public function getExtendedAccessToken() {\n\n try {\n // need to circumvent json_decode by calling _oauthRequest\n // directly, since response isn't JSON format.\n $access_token_response =\n $this->_oauthRequest(\n $this->getUrl('graph', '/oauth/access_token'),\n $params = array( 'client_id' => $this->getAppId(),\n 'client_secret' => $this->getApiSecret(),\n 'grant_type'=>'fb_exchange_token',\n 'fb_exchange_token'=>$this->getAccessToken(),\n ));\n\n } catch (FacebookApiException $e) {\n // most likely that user very recently revoked authorization.\n // In any event, we don't have an access token, so say so.\n return false;\n }\n\n if (empty($access_token_response)) {\n return false;\n }\n\n $response_params = array();\n parse_str($access_token_response, $response_params);\n if (!isset($response_params['access_token'])) {\n return false;\n }\n\n return $response_params['access_token'];\n }\n\n\nUnfortunanely it still won't work my access token expired after 2 hours so I tried also this:\n\n public function getSimpleExtendedAccessToken(){\n\n $request = 'https://graph.facebook.com/oauth/access_token?\n client_id='. $this->getAppId(). \n '&client_secret=' .$this->getApiSecret(). \n '&grant_type=fb_exchange_token\n &fb_exchange_token=' .$this->getAccessToken();\n\n $response = file_get_contents($request);\n $params = null;\n parse_str($response, $params);\n return $params['access_token'];\n}\n\n\nand this one also expired after 2 hours. But when I checked what was inside the array $params in the second function there was written:\n\n\n Array ( [access_token] => AAAFM5sO7[...] [expires] => 4897 )\n\n\n(That part: \"AAAFM5sO7[...]\" is of course my access token number)\n\nAll access tokens which I received are the same: first one from getAccessToken(), second one from getExtendedAccessToken() and third one from getSimpleExtendedAccessToken(). \n\nOf course when I ask addtionaly more and more for extended access token the expiration number doesn't renew but it's counting down, and that is correct from the point of view of the Facebook documentation, because you can't ask for new access token each minute, but why I can't get 60 days access token?\n\nCan anyone help me because I'm a bit cofused?"

"Seeming contradiction typechecks in Idris",
"I have the following definition of a predicate on vectors that identifies if one is a set (has no repeated elements) or not.

Why does the pattern matching on (False ** isNotMember) = fun_1 x xs typecheck?\n\nEven more confusing, something like the following typechecks too:\n\nexample : IsSet [1,1]\nexample = fun_2 [1,1]\n\n\nThis seems like a contradiction, based on the definition of IsSet and ElemBool above.\nThe value for example idris evaluates is the following:\n\ncase block in fun_2 Integer\n 1\n 1\n [1]\n (constructor of Prelude.Classes.Eq (\\meth =>\n \\meth =>\n intToBool (prim__eqBigInt meth\n meth))\n (\\meth =>\n \\meth =>\n not (intToBool (prim__eqBigInt meth\n meth))))\n (IsSetCons ElemBoolNil IsSetNil)\n (True ** ElemBoolCons ElemBoolNil) : IsSet [1, 1]\n\n\nIs this an intended behaviour? Or is it a contradiction? Why is the value of type IsSet [1,1] a case block? I have the %default total annotation at the top of the file so I don't think it has anything to do with partiality, right?\n\nNote: I'm using Idris 0.9.18"
