Stop working in Android Studio 's Emoulator -

I have a simple problem with my small calculator in Android studio (below is my code).

When I run it in the emulator app stop working. Can someone help me?

You can not try to find a view in an activity before calling setContentView ().

vba - Outlook checks e-mails only in specific time frame -

I need a VBA Outlook macro that checks the items in the folder in a specific time limit. At the moment my code goes through all the fairs in the specified folder, but this is not an option because the folder has thousands of mails, so the macro takes it forever to run, any ideas, how to check the script For example, Mail: 3/16/2015 to 12:00 to 3/16/2015 2:00 pm and do not check any e-mails outside of that time frame?

I have this at present:

  sub ExportToExcel () dim appExcel Excel.Application dim form of Excel.Workbook Slow Excel.Worksheet dim RNG Excel.Range dim WorkbookFile as String Dimmed Outlook as Outlook 2007.MailItem Dim NMS Outlook.NameSpace is retarded as the Outlook.MAPIFLDM FLD itm object in the form of an object's folder path of an existing Excel workbook and File name workbookFile = "C: \ Users \ OutlookItems.xls" 'Export Export Folder NMS = ApplicationSetup GetNamespace ("MAPI") is to handle potential errors with the Fld = nms.PickFolder 'Select Folder dialog box. If FFD is nothing, then there are no mail messages to export "MSBBC", vbOKOnly, exit "_" error sub alcif fld.DefaultItemType & lt; & Gt; OlMailItem Then there is no mail message for "export export", vbOKOnly, _ "error" exit subfifth fld.Items.Count = 0 then MsgBox "no mail is exported to the message", vbOKOnly, _ "error "Exit the sub-end if you open the Excel workbook and set the appExcel = CreateObject (" Excel.Application ") set WKB = appExcel.Workbooks.Open (workbookFile) set = wkb.Sheets (1) wks.Activate appExcel Application.Visible = true set RNG = wks.Range ("A1") 'Copy Item item in the mail folder. In each ITM fld.Items if itm.Class = Set up Outlook.OlObjectClass.olMail then msg = itm if InStr (msg.Subject, "Error in WU_Send") & gt; 0 and dated ("H", msg. ston, now) & lt; = 2 then RNG Offset (0, 4). Value = msg.Bydy set RNG = RNG .offet (1, 0) and end and end and end and sub  

and the problem is in this special part:

< Pre> for each ITM in fld.Items if itm.Class = Set up Outlook.OlObjectClass.olmail then go to msg = itm if InStr (msg.Subject, "Error in WU_Send") & gt; 0 and dated ("H", msg. ston, now) & lt; = 2 then

How do I tell the code to only look at the specified hour and time on the e-mail? Ignore the rest?

Thanks or your answers, comments and suggestions in advance!

Instead of going through all the objects in the folder instead of using the / or methods of the items Have to do. For example:

  sub DemoFindNext () dim MyNamespace Outlook.NameSpace dim tdystart Date dated tdyend dated date myAppointments Outlook.Items slow currentAppointment Outlook.AppointmentItem set as MyNamespace = Application.GetNamespace In the form of as ("MAPI") tdystart = VBA.Format (now, "short date") tdyend = VBA.Format (now +1, "short date") set myAppointments = myNameSpace.GetDefaultFolder ( OlFolderCalendar). Items set currentAppointment = myAppointments.Find ("[Start]> gt; =" "and & quot; and" "" and [start]  
 
 
       
 
 
 
 
   
 
 In addition to this you can find the application class method helpful. The main benefits of using advanced search method are listed below: 
 
 
 Search The second thread is carried out in the advanced search system after running automatically in the background, Thread is not required to run manually. 
 
 Any type of type, mail, appointment, calendar, notes etc. are likely to be searched in any place, i.e. beyond the scope of a fixed folder 
 
 DASL queries Restrict full support for (custom properties can also be used to search) and find / locate the next methods can be applied to a particular item collection. . You can read more about this in the filtering article in MSDN. To improve search performance, instant search keywords can be used if Instant Search is enabled for the store (see Store IsInstantSearchEnabled property in Store category). 
 
 You can stop the search process at any time by using the stop. Method of search class 
 
 

emacs24 - Use search script froma previous search emacs -

I'm an emacs newbie I use C-S "text" for the text I have an entry Instead of searching for it instead of writing it, how do I choose it? For example, there is a shortcut to remember the C-S "Text1" C-S "Text2" lesson 1, so when I search for it, I do not have to write it again?

If you press CS CS , then whatever you search for Will search last time. By using

MP you can run in search history and edit search strings as well. Press RET to continue the search.

I recommend starting with a storyboard. Is this cell always a Do not matter (use stationary cells for your UIView in the Stotboard in the storyboard), or do you add cells programmatically Are planning on (use dynamic cells and define a prototype cell).

The following is a great tutorial on strobobs, which should help you get started:

web services - JIRA to ServiceNow Integration -

Is there a way for GIRA to listen to build build and configure it to be set up with tickets? Service Alteration Almost Almost Similar Information about JIRA Construction?

If so, what can I see on some plugins, listeners, web servers? Where can I create these configurations in Gears system settings? Is such an API already created?

This service can be easily completed with the new REST API. You can use "Table API" directly in the Change Request table. If you need to change any data before entering, you can define a conversion map using "Import API" and. If you are on the earlier version, which does not have a REST API, then there are some other web service options you can use.

Here are some links to useful documentation you can find:

javascript - Populating arrays after their definition -

I have a recipe containing a ul containing li Separate recipe content for page I am trying to get those elements and trying to store them in a JavaScript array within an object. I already know the title of the recipe, so I put that object property in title , but I do not know how many elements are there for each recipe. Val (), content: [ingredient, optional]} $ .eee ($ ('Ul.ingitals'> li>, h4'), function (index, element) {recipeobj.ingredients [index] .ingredient = $ (Component). Html (); recipeobj.ingredients [index]. Optional = false;})

If I try to console.log (recipeobj.ingredients) I get the error Uncaught ReferenceError: The component is not defined

There is no doubt that it is simple, I have to use arrays rarely in javascript So that Have a little experience with

open your console and run it

< Div class = "snippet" data-lang = "js" data-hide = "wrong">

  var recipeobj = {title: $ ('h3.title'). Html (), // content is now empty for the ingredients: []}; $ .each ($ ('ul.ingredients & gt; li & gt; h4'), function (index, component) {// name var name = $ (component) .html (), // find out what this Paste a new component in 'Optional' (use square here) optional = $ (component) .hasClass ('optional'); // array at recipeobj.ingredients.push ({name, optional: optional}) ;}); Console.log (recipeobj);  

  & lt; Script src = "https: //ajax.googleapis com / ajax / libs / jquery / 2.1.1 / jquery.min.js" & gt; & Lt; / Script & gt; & Lt; H3 class = "title" & gt; Pork and beans & lt; / H3 & gt; & Lt; Ul class = "content" & gt; & Lt; Li & gt; & Lt; H4 & gt; Pork & lt; / H4 & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; H4 & gt; Beans & lt; / H4 & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; H4 square = "optional" & gt; Salt * & lt; / H4 & gt; & Lt; / Li & gt; & Lt; / Ul & gt; This output should be:

php - Sort array of file lines by alphabetical -

I am reading a text file of email addresses and only outputing to the domain (with the @ symbol). I would like to make this list alphabet and then output to display on screen

My code is so far like this:

  & lt ;? Php $ file_handle = fopen ("file.txt", "R"); While (.fif ($ file_handle)) {$ line = fgets ($ file_handle); $ Parts = explosion ("@", $ line); $ Id = $ parts [count ($ part) - 1]; Echo "@" $ id "& lt; br & gt;"; } Fclose ($ file_handle); ? & Gt;  

How can I bring the list to alphabet?

This should work for you:

(Here I just click on the file Line. Then I go through each line from where I just array the array to the domain $ lines in the end I sort and print the array with it)

  & lt ;? Php $ lines = array_map (function ($ v) {return "@". Explosion ("@", $ V) [1];}, file ("test.txt")); Type ($ lines); External currency ($ lines as lines) $ line echo "
"; ? & Gt;  

Example input / output:

  ab@x.com ac@a.de es@b.cu  

< P>

  @ a.de @ b.cu @x.com  

java - Bubble Sort with compare method not running -

This is a follow up to my previous question that I had asked yesterday. I have written a bubble sort method which analyzes an array of strings and returns the number of similarities, which provides the alphabet in order to order the method (assignment is to write several sorting methods and each Graph a number of comparisons to compare one, to see which is the most efficient).

This is my code:

  public static zero main (string [] args) {string [] test_array = {"bill", "fill", "Adam" }; / * System.out.println (compare ("orange", "boogie")); * / System.out.println (Bubble sort (test_array)); } Comparison of public static int (string A, string b) {int len ​​= Math.min (a.length (), b.length ()); // Looping through every character, if CH is less than chb, then method 1 returns, and so on. For {int i = 0; i & lt; len; i ++} {char cha = a.charAt (i); Four chb = b.chart (i); If (cha leftibbs; CHB) {return -1; } And if (Ch & gt; chb) {return1; }} // Now we eat for the length of the word because it can be the same word if (a.length () & lt; b.length ()) -1 return; Else if (a.length ()> gt; b.length ()) back 1; // appears to be the same string, then return 0. And return 0; } Public Static Ent Bubble Sort (string [] test_array) {Boolean swap = true; // variable to track the number of comparisons Int compNumber = 0; While (swap == true) {swapped = false; (Int i = 1; i & lt; test_array.length; i ++) for {// compn number compNumber ++; If (test_array [I-1], test_array [i]) & gt; 0) {// change variable by using a floating variable string logical = test_array [i-1]; Test_array [i-1] = test_array [i]; Test_array [i] = floating; Swap = true; } Else {swapped = true; }}} Return COMPNumber; }  

So the comparison method (given by array) compares two stars and determines whether they are in alphabetical order (return -1) or not (1 return) , Or the same word (return 0). Then, the bubble sort method compares the method to go through the array, and it then creates a switch, whereas the number of loops in my Vampan-NAB variable is computed (hence the number of comparisons).

It is compiled exactly, but it does not stop running unfortunately and does not return anything. I have waited 5 minutes so I have decided that something is wrong, maybe with my loop I am unable to find any problem, which has manipulated the parameters of many times, can someone help me? thank you in advanced.

"swap" will always be correct, so looping will never end. I think that you put swap = wrong in the second description

php - Curl download all files in a directory -

I am using PHP curl to capture files from a URL. The file names are currently hard coded and I am trying to create it so that it can download all the files in a specific directory. Any point in the right direction would be good. Thank you.

Please note that I have a "read" right in a directory, I do not have FTP access or anything else.

Php $ server_url = $ _GET ['server_url']; $ Server = $ _GET ['server']; // It needs to be changed for all files ($ i = 140512; $ i & lt; = 150316; $ i ++) {$ id = base64_encode ($ i); $ File_name = $ server_url $ I ' Log '; Curl_setopt ($ ch, CURLOPT_URL, $ file_name); Curl_setopt ($ CH, CURLOPT_RETURNTRANSFER, 1); // return data string as idle peer verification curl_setopt ($ CH, CURLOPT_SSL_VERIFYPEER, FALSE); // // disabled host verification curl_setopt ($ CH, CURLOPT_SSL_VERIFYHOST, incorrect); // Real Browser Client String Curl_setopt ($ CH, CURLOPT_USERAGENT, "Mozilla / 4.0 (compatible; MSIE 5.01; Windows NT 5.0)" Spoof; $ output = curl_XC ($ CH); // Capture data in output variable if (! DIR ('sites /'. $ Server. '_ LOGS')) {MKDIR ('sites /' .a server. '_ LOGS');} If ($ output! = False) {file_put_contents ('sites /'. $ Server. 'LOGS'. '/ U_ex'. Base64_decode ($ id). '.log', $ output);} Curl_close ($ ch);}? & Gt;  

Curls supports FTP, You can use it to make a file and then download each file. I found an example using PHP curls in the previous answer.

How do I change hostname on Android? (and reachable by a ping?) -

I need to change the hostname of my tablet in my Android application. I think the idea of ​​"ping me-tablet" Have to work properly. To accomplish this, I have given the following commands (programmatic) through ADB:

  su setprop net.hostname & lt; New_hostname & gt;  

When I give it:

  getprop net.hostname  

However, the change was not notified on the network So ... if I ping the device, then nothing works.

I have seen this resource: but I'm not sure that it solves the problem.

Solution (such as manually editing the host file, though I should do it for every connected device ... or change the router directly that I can not do all the time), but this It does not seem possible.

Any thoughts? Thanks :)

mongodb - Querying sub documents in mongoose -

मॉन्गोस में मॉडल का पालन करें:

  var specie = mongoose.Schema ({आदेश: स्ट्रिंग, परिवार: स्ट्रिंग, जीनस: स्ट्रिंग, प्रजातियां: स्ट्रिंग, गुण: [{संपत्ति: स्ट्रिंग, मान: स्ट्रिंग}]});  

मैं एक क्वेरी बनाने की कोशिश कर रहा हूं जो गुण सरणी में विशिष्ट मानों के आधार पर दस्तावेज़ वापस करेगा।

नीचे मेरी क्वेरी का एक उदाहरण है:

  var query = {$ and: [{"properties.property": "पंखों की संख्या", "properties.value ":" 2 "}, {" properties.property ":" एंटीना अंत "," properties.value ":" clubbed "}}  

मैंने सोचा कि यह क्वेरी काम करेगी लेकिन यह वास्तव में सभी दस्तावेज़ों को "पंखों की संख्या" और "ऐन्टेना एंड" और एक मान "4" और मूल्य "क्लबबर्ड" प्रदान करता है।

{property: "पंखों की संख्या", मान: "2"} और

{संपत्ति: "ऐन्टेना एंड", मान: "क्लबबर्ड"}

हालांकि उपरोक्त प्रश्न उन दस्तावेजों को भी देता है जिनके पास संपत्ति है:

  {property : "पैर की संख्या", मूल्य: "2"}  

मैं इसका समाधान कैसे कर सकता हूं?

मेरा मानना ​​है कि मुझे अपना जवाब मिला। मुझे क्वेरी में $ elemMatch का उपयोग करना होगा:

  var query = {$ और: [{properties: {$ elemMatch: {property: "पंखों की संख्या", मान: "2"} }}, {संपत्तियों: {$ elemMatch: {"property": "ऐन्टेना अंत", "मान": "क्लबबर्ड"}}}]}  

संसाधन लिंक जोड़ना:

यह सही परिणाम वापस आ रहा है।
