i have single form - depending link user clicks display form, want different hidden params passed record , saved upon submission. there nice way this? in advance! for instance: <%= link_to 'general request', new_request_path %> <%= link_to 'project request', new_request_path %> ### -> set request.project = true <%= link_to 'administrative request', new_request_path %> ### -> set request.admin = true for examples, you'd use: <%= link_to 'project request', new_request_path(project: true) %> which produce link http://127.0.0.1:3000/request?project=true and <%= link_to 'administrative request', new_request_path(admin: true) %> which produce link http://127.0.0.1:3000/request?admin=true

i following example c# in nutshell. according text following code supposed non blocking, find form not display until 5 seconds have passed. private void form1_load(object sender, eventargs e) { var tcs = new taskcompletionsource<int>(); new thread(() => {thread.sleep(5000); tcs.setresult(42); }).start(); task<int> task = tcs.task; messagebox.show(task.result.tostring()); } i have feeling it's thread.sleep() , instead of putting new thread sleep, it's putting main thread sleep. why blocking ui thread? when call task.result.tostring() (in messagebox.show ) task class has mechanism waits task finished before giving result (as doesn't have until task finishes. here's proof: private void form1_load(object sender, eventargs e) { var tcs = new taskcompletionsource<int>(); new thread(() => {thread.sleep(5000); tcs.setresult(42); }).start(); task<int> task = tcs.task; thread.sleep(2500); ...

i'd deconstruct raw reports received hid_read function of hidapi . as understand, can achieved using information device's report descriptors. when trying query descriptors, lost somewhere between hid spec , using methods available in hidapi . i love see concrete c or node-hidapi based example queries , enumerates report descriptors device — perhaps mouse keep things simple? i asked alan ott email this, , responded no follows: hidapi not provide functions getting or parsing report descriptor. since hidapi talking custom devices, these devices contain or vendor-defined report items anyway.

i implementing interface knows email of user before user has logged in. preferably, since i'm using authentication i'd use openid opposed oauth2. however, if user logged in multiple google accounts user forced select accounts. i'd prefer if tell google wanted specific google account logged in user not have guess account i'm looking (given they're logged in account). better ux. i know google's oauth2 can specify login_hint skip account selection screen if user logged in account specified in login_hint parameter. reference, https://developers.google.com/accounts/docs/oauth2login does know of similar openid? i've read google's documentation , seems it's not possible, perhaps i'm missing something. appreciated! unfortunately, openid doesn't support login hint feature. i recommend use oauth2 if possible, given oauth2 can used authentication only.

hi new php , having 3 php arrays namely bookname, bookprice , bookisbn, need insert values like "bookisbn" "bookname" "bookprice" mysql eg: isbn1 bookname1 bookprice1 isbn2 bookname2 bookprice2 isbn3 bookname3 bookprice3 as of tried iterate 3 arrays like, foreach($booknamearray $bookname && $bookpricearray $bookprice && $bookisbnarray $bookisbn) { .. } and while($booknamearray $bookname && $bookpricearray $bookprice && $bookisbnarray $bookisbn){ .. } nothing worked me, please kindly me out achieve this. thanks in advance, naveen. assuming have same number of elements, can use loop, , make string of values: for($i = 0; $i < count($booknamearray); $i++) { $str = $booknamearray[$i] .

i experimenting java networking , found bit odd thing, suppose have url url = new url("http://www.google.com"); urlconnection con = url.openconnection(); then can call methods, con.getcontentlength() , on , give me correct values, despite didn't envoke con.connect() . how can be? mean, from/how urlconnection gets headers, didn't invoke con.connect() yet, no requests sent , no headers should available @ moment. the actual tcp connect happens implicitly when call method requires response, such getcontentlength(), getinputstream(), getresponsecode(). doesn't happen @ openconnection(). request sent @ point. unless using 1 of streaming modes , you're doing put or post request content, in case connection opened when start writing request.
