• Check if IsCallback on Application_BeginRequest

  - by user136405

  I have a web application (.NET 3.5) that has this code in Global.asax: Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) LinkLoader() PathRewriter() PathAppender() End Sub I want all those functions inside to get called except for when it's an AJAX call back. So, ideally I would have it changed to: Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) If not Page.IsCallback then LinkLoader() PathRewriter() PathAppender() End If End Sub But there is not access to the page object here. So, basically my question is: How do I check if the request is an AJAX call back inside Application_BeginRequest? Thank you very much for any feedback.

• Using traversal by pointer to check whether a string is repeated

  - by Bob John

  bool repeat_char(char *s, int n); //R: s is a C-string of at least n non-NUL characters and n > 0 //E: returns true if the first n characters are fully repeated throughout the string s, false // otherwise. I'm having trouble implementing this function using traversal by pointer. I was thinking that I could extract the first n characters from s, then use that in a comparison with s, but I'm not sure how I could do that. If I'm traversing through s one character at a time, how can I check that it matches a block of text, such as the first n characters of s? Thanks!

• How to diagnose and fix Kernel Panic Fatal Machine Check error?

  - by 0x4a6f4672

  I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. A fine machine comparable to a Macbook Pro. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following Machine Check Exception error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-( I also disabled the Execute Disable Bit (EDB) flag in the BIOS. EDB is an Intel hardware-based security feature that can help reduce system exposure to viruses and malicious code. Since I disabled it, the error did occur less frequently, but it still appears occasionally :-( It seems to be the same error as described here and here. Maybe a Samsung specific Kernel problem? A similar error also happens on a Samsung Ultrabook Series 9 (which seems to be kernel bugs 49161 and 47121). At my Samsung Series 7, it still occurs for instance during booting on battery after "Checking battery state". Perhaps anyone else has an idea? These Kernel Panic errors are reallly annoying..

• How can I check Internet connectivity in a console?

  - by Ashfame

  Is there an easy way to check Internet connectivity from console? I am trying to play around in a shell script. One idea I seem is to wget --spider http://www.google.co.in/ and check the HTTP response code to interpret if the Internet connection is working fine. But I think there must be easy way without the need of checking a site that never crash ;) Edit: Seems like there can be a lot of factors which can be individually examined, good thing. My intention at the moment is to check if my blog is down. I have setup cron to check it every minute. For this, I am checking the HTTP response code of wget --spider to my blog. If its not 200, it notifies me (I believe this will be better than just pinging it, as the site may under be heavy load and may be timing out or respond very late). Now yesterday, there was some problem with my Internet. LAN was connected fine but just I couldn't access any site. So I keep on getting notifications as the script couldn't find 200 in the wget response. Now I want to make sure that it displays me notification when I do have internet connectivity. So, checking for DNS and LAN connectivity is a bit overkill for me as I don't have that much specific need to figure out what problem it is. So what do you suggest how I do it?

• Forbidden Patterns Check-In Policy in TFS 2010

  - by Jaxidian

  I've been trying to use the Forbidden Patterns part of the TFS 2010 Power Tools and I'm just not understanding something - I simply cannot get anything to change as I try to use this! I'm using the version that was released recently (I believe April 23, 2010), so it's not an old version. First off, yes, I know it's regex based, so let's clear that doubt... I have tried to block the following scenarios: 1) I have modified all of my T4 EF templates to generate files named EntityName.gen.cs. I then attempted to prevent TFS from wanting to check those files in. I used the regular expression \.gen\.cs\z and it didn't change a single thing! I even tried it without the \z and nadda! 2) I don't want app.config and web.config files to be checked-in by default because we have these things stored into app.config.base and web.config.base files that our build scripts use to generate our per-environment app.config and web.config files. As such, I tried the following regexes and again, nothing worked! web\.config\z, app\.config\z, web\.release\.config\z and web\.debug\.config\z. What is it that I am screwing up with this?

• ASP.NET Membership ChangePassword control - Need to check for previous password

  - by Steve

  Hi guys, I have a new table that hold old passwords, I need to check if there is a match. If there is a match I need the ChangePassword contol to NOT change the password. I need to tell the user that this password was used and pic a new one. I can't seem to be able to interrupt the control from changing the password. Maybe I am using the wrong event. Here is a piece of my code, or how I wish it would work. I appreciate all your help. protected void ChangePassword1_ChangedPassword(object sender, EventArgs e) { MembershipUser user = Membership.GetUser(); string usrName = ""; if (user != null) { string connStr = ConfigurationManager.ConnectionStrings["LocalSqlServer"].ConnectionString; SqlConnection mySqlConnection = new SqlConnection(connStr); SqlCommand mySqlCommand = mySqlConnection.CreateCommand(); mySqlCommand.CommandText = "Select UserName from OldPasswords where UserName = 'test'"; mySqlConnection.Open(); SqlDataReader mySqlDataReader = mySqlCommand.ExecuteReader(CommandBehavior.Default); while (mySqlDataReader.Read()) { usrName = mySqlDataReader["UserName"].ToString(); if (usrName == user.ToString()) { Label1.Text = "Match"; } else { Label1.Text = "NO Match!"; } }

• How to check and match the possible combinations of arraylist elements

  - by Jessy

  String [] A = {"High","Medium","Low"}; String [] B = {"High","Medium","Low"}; String [] C = {"High","Medium","Low"}; String [] D = {"High","Medium","Low"}; String [] E = {"High","Medium","Low"}; String [] F = {"High","Medium","Low"}; JComboBox Ai = new JComboBox(A); JComboBox Bi = new JComboBox(B); JComboBox Ci = new JComboBox(C); JComboBox Di = new JComboBox(C); JComboBox Ei = new JComboBox(E); JComboBox Fi = new JComboBox(F); .... //add the user choice in arrayList ArrayList<String> a = new ArrayList<String>(); a.add((String) Ai.getSelectedItem()); a.add((String) Bi.getSelectedItem()); a.add((String) Ci.getSelectedItem()); a.add((String) Di.getSelectedItem()); a.add((String) Ei.getSelectedItem()); a.add((String) Fi.getSelectedItem()); Scenario: On each comboBox, user need to choose one, which mean there are 6 choices at the end. There are 6*5*4*3*2*1 = 720 possible combinations of choices made by the user. What is the best way to check and match the user choice without writing the 720 else if ? e.g. if(Ai=="High" && Bi=="High" && Ci=="Low" && Di=="High" && Ei=="Low" && Fi=="Medium") { System.out.println("Good Choice"); } Thank you.

• How to check if returning View is of type PartialViewResult or a ViewUserControl

  - by mare

  In the method FindView() I have to somehow check if the View we are requesting is a ViewUserControl. Because otherwise I get an error saying: "A master name cannot be specified when the view is a ViewUserControl." This is my custom view engine code right now: public class PendingViewEngine : VirtualPathProviderViewEngine { public PendingViewEngine() { // This is where we tell MVC where to look for our files. /* {0} = view name or master page name * {1} = controller name */ MasterLocationFormats = new[] {"~/Views/Shared/{0}.master", "~/Views/{0}.master"}; ViewLocationFormats = new[] { "~/Views/{1}/{0}.aspx", "~/Views/Shared/{0}.aspx", "~/Views/Shared/{0}.ascx", "~/Views/{1}/{0}.ascx" }; PartialViewLocationFormats = new[] {"~/Views/{1}/{0}.ascx", "~/Views/Shared/{0}.ascx"}; } protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) { return new WebFormView(partialPath, ""); } protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) { return new WebFormView(viewPath, masterPath); // this line produces the error because we cannot set master page on ASCXs, so I need an "if" here } public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache) { if (controllerContext.HttpContext.Request.IsAjaxRequest()) return base.FindView(controllerContext, viewName, "Modal", useCache); return base.FindView(controllerContext, viewName, "Site", useCache); } } The above ViewEngine fails on calls like this: <% Html.RenderAction("Display", "MyController", new { zoneslug = "some-zone-slug" });%> The action I am rendering here is this: public ActionResult Display(string zoneslug) { WidgetZone zone; if (!_repository.IsUniqueSlug(zoneslug)) zone = (WidgetZone) _repository.GetInstance(zoneslug); else { // do something here } // WidgetZone used here is WidgetZone.ascx, so a partial return View("WidgetZone", zone); } I cannot use RenderPartial because you cannot send route values to RenderPartial the way you can to RenderAction. To my knowledge there is no way to provide RouteValueDictionary to RenderPartial() like the way you can to RenderAction().

• C# Active Directory - Check username / password

  - by Michael G

  I'm using the following code on Windows Vista Ultimate SP1 to query our active directory server to check the user name and password of a user on a domain. public Object IsAuthenticated() { String domainAndUsername = strDomain + @"\" + strUser; DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, strPass); SearchResult result; try { //Bind to the native AdsObject to force authentication.

• How to check for server side update in iPhone application Web service request

  - by Nirmal

  Hello All.... I have kind of Listing application for iPhone application, which always calling a web service to my php server and fetching the data and displaying it onto iPhone screen. Now, the thing to consider in this scenario is, my iPhone application everytime requesting on the server and fetching the data. But now my requirement is like I want to replace following set of actions with above one : - Everytime when my application is launched in iPhone, it should check for the new data at the server`. - And if server replies "true" then only my iPhone application will made a request to fetch the data. - In case of "false", my iPhone application will display the data which is already cached in local phone memory. Now to implement this scenario at server side (which has php, mysql), I am planning with the following solution : Table : tblNewerData id newDataFlag == ============ 1 true Trigger : tgrUpdateNewData Above trigger will update the tblNewerData - newDataFlag field on Insert case of my main table. And every time my iPhone app will request for tblNewerData-newDataFlag field, and if it found true then only it will create new request, and if it founds false then the cached version of data will be displayed. So, I want to know that, is it the correct way to do so ? or else any other smart option available ? Thanks in advance.

• Check if files in a directory are still being written in Windows Batch File

  - by FMFF

  Hello. Here's my batch file to parse a directory, and zip files of certain type REM Begin ------------------------ tasklist /FI "IMAGENAME eq 7za.exe" /FO CSV > search.log FOR /F %%A IN (search.log) DO IF %%~zA EQU 0 GOTO end for /f "delims=" %%A in ('dir C:\Temp\*.ps /b') do ( "C:\Program Files\7-Zip\cmdline\7za.exe" a -tzip -mx9 "C:\temp\Zip\%%A.zip" "C:\temp\%%A" Move "C:\temp\%%A" "C:\Temp\Archive" ) :end del search.log REM pause exit REM End --------------------------- This code works just fine for 90% of my needs. It will be deployed as a scheduled task. However, the *.ps files are rather large (minimum of 1GB) in real time cases. So the code is supposed to check if the incoming file is completely written and is not locked by the application that is writing it. I saw another example elsewhere, that suggested the following approach :TestFile ren c:\file.txt c:\file.txt if errorlevel 0 goto docopy sleep 5 goto TestFile :docopy However this example is good for a fixed file. How can I use that many labels and GoTo's inside a for loop without causing an infinite loop? Or is this code safe to be used in the For Loop? Thank you for any help.

• C++: Check istream has non-space, non-tab, non-newline characters left without extracting chars

  - by KRao

  I am reading a std::istream and I need to verify without extracting characters that: 1) The stream is not "empty", i.e. that trying to read a char will not result in an fail state (solved by using peek() member function and checking fail state, then setting back to original state) 2) That among the characters left there is at least one which is not a space, a tab or a newline char. The reason for this is, is that I am reading text files containing say one int per line, and sometimes there may be extra spaces / new-lines at the end of the file and this causes issues when I try get back the data from the file to a vector of int. A peek(int n) would probably do what I need but I am stuck with its implementation. I know I could just read istream like: while (myInt << myIstream) {...} //Will fail when I am at the end but the same check would fail for a number of different conditions (say I have something which is not an int on some line) and being able to differentiate between the two reading errors (unexpected thing, nothing left) would help me to write more robust code, as I could write: while (something_left(myIstream)) { myInt << myIstream; if (myStream.fail()) {...} //Horrible things happened } Thank you!

• For commands to check duped/multiple mc's.

  - by Desmond

  Currently I'm working on a platform type game. I have a for loop in place to check weather or not the players feet are touching the ground. I had this; for (i=0; i<5; i++) { //There are 5 floors if (this.feet.hitTest(_root["g"+i])) { _root.mc.groundTouch = true; //triggers the mc falling } } This works fine only if one of the floors exist(IE if floor1 is on the stage, but floor2-5 aren't); So to try and counter it I tried using; for (i=0; i<5; i++) { if (this.feet.hitTest(_root["floor"+i])) { _root.mc.groundTouch = true; //triggers the mc falling } if (!this.feet.hitTest(_root["floor"+i])) { _root.mc.groundTouch = false; } } This obviously doesn't work because in order for it to function properly, _root.mc.feet would have to be touching all 5 instances of "floor". So my question is; How do I get the code to make _root.mc.groundTouch = true if _root.mc.feet is touching any of the floor instances, but make _root.mc.groundTouch = false only if its touching none of the floor instances? I know that if I really wanted to I could do something like if (_root.mc.feet.hitTest(_root.floor1) && !_root.mc.feet.hitTest(_root.floor2) && etc) But to save myself time, and to give myself the ability to add floors without altering more then i<5 to the amount of floors I have, I would prefer a easier method hopefully something to do with for loops. Thank you ahead of time and your help is very much appreciated

• How to use Common Table Expression and check no duplication in SQL Server

  - by vodkhang

  I have a table references to itself. User table: id, username, managerid and managerid links back to id Now, I want to get all the managers including direct manager, manager of direct manager, so on and so forth... The problem is that I do not want to have a unstop recursive sql. So, I want to check if an id alreay in a list, I will not include it anymore. Here is my sql for that: with all_managers (id, username, managerid, idlist) as ( select u1.id, u1.username, u1.managerid, ' ' from users u1, users u2 where u1.id = u2.managerid and u2.id = 6 UNION ALL select u.id, u.username, u.managerid, idlist + ' ' + u.id from all_managers a, users u where a.managerid = u.id and charindex(cast(u.id as nvarchar(5)), idlist) != 0 ) select id, username from all_managers; The problem is that in this line: select u1.id, u1.username, u1.managerid, ' ' The SQL Server complains with me that I can not put ' ' as the initialized for idlist. nvarchar(40) does not work as well. I do not know how to declare it inside a common table expression like this one. Usually, in db2, I can just put varchar(40) My sample data: ID UserName ManagerID 1 admin 1 2 a 1 3 b 1 4 c 2 What I want to do is that I want to find all managers of c guy. The result should be: admin, a, b. Some of the user can be his manager (like admin) because the ManagerID does not allow NULL and some does not have direct manager. With common table expression, it can lead to an infinite recursive. So, I am also trying to avoid that situation by trying to not include the id twice. For example, in the 1st iteration, we already have id : 1, so, in the 2nd iteration and later on, 1 should never be allowed. I also want to ask if my current approach is good or not and any other solutions? Because if I have a big database with a deep hierarchy, I will have to initialize a big varchar to keep it and it consumes memory, right?

• python: nonblocking subprocess, check stdout

  - by Will Cavanagh

  Ok so the problem I'm trying to solve is this: I need to run a program with some flags set, check on its progress and report back to a server. So I need my script to avoid blocking while the program executes, but I also need to be able to read the output. Unfortunately, I don't think any of the methods available from Popen will read the output without blocking. I tried the following, which is a bit hack-y (are we allowed to read and write to the same file from two different objects?) import time import subprocess from subprocess import * with open("stdout.txt", "wb") as outf: with open("stderr.txt", "wb") as errf: command = ['Path\\To\\Program.exe', 'para', 'met', 'ers'] p = subprocess.Popen(command, stdout=outf, stderr=errf) isdone = False while not isdone : with open("stdout.txt", "rb") as readoutf: #this feels wrong for line in readoutf: print(line) print("waiting...\\r\\n") if(p.poll() != None) : done = True time.sleep(1) output = p.communicate()[0] print(output) Unfortunately, Popen doesn't seem to write to my file until after the command terminates. Does anyone know of a way to do this? I'm not dedicated to using python, but I do need to send POST requests to a server in the same script, so python seemed like an easier choice than, say, shell scripting. Thanks! Will

• XSL check param length

  - by AdRock

  I need to check if a param has got a value in it and if it has then do this line otherwise do this line. I've got it working whereas I don't get errors but it's not taking the right branch Here is the template which holds the html in the XSL stylesheet <xsl:call-template name="volunteer_role"> <xsl:with-param name="volrole" select="volunteer/roles" /> </xsl:call-template> and here is the template where there is a choice whether to take this brancg or that brach depending if the param is empty <xsl:template name="volunteer_role"> <xsl:param name="volrole" select="'Not Available'" /> <div class="small bold">ROLES:</div> <div class="large"> <xsl:choose> <xsl:when test="string-length($volrole)!=0"> <xsl:value-of select="$volrole" /> </xsl:when> <xsl:otherwise> <xsl:text> </xsl:text> </xsl:otherwise> </xsl:choose> </div> </xsl:template>

• Post-loading : check if an image is in the browser cache

  - by Mathieu

  Short version question : Is there navigator.mozIsLocallyAvailable equivalent function that works on all browsers, or an alternative? Long version :) Hi, Here is my situation : I want to implement an HtmlHelper extension for asp.net MVC that handle image post-loading easily (using jQuery). So i render the page with empty image sources with the source specified in the "alt" attribute. I insert image sources after the "window.onload" event, and it works great. I did something like this : $(window).bind('load', function() { var plImages = $(".postLoad"); plImages.each(function() { $(this).attr("src", $(this).attr("alt")); }); }); The problem is : After the first loading, post-loaded images are cached. But if the page takes 10 seconds to load, the cached post-loaded images will be displayed after this 10 seconds. So i think to specify image sources on the "document.ready" event if the image is cached to display them immediatly. I found this function : navigator.mozIsLocallyAvailable to check if an image is in the cache. Here is what I've done with jquery : //specify cached image sources on dom ready $(document).ready(function() { var plImages = $(".postLoad"); plImages.each(function() { var source = $(this).attr("alt") var disponible = navigator.mozIsLocallyAvailable(source, true); if (disponible) $(this).attr("src", source); }); }); //specify uncached image sources after page loading $(window).bind('load', function() { var plImages = $(".postLoad"); plImages.each(function() { if ($(this).attr("src") == "") $(this).attr("src", $(this).attr("alt")); }); }); It works on Mozilla's DOM but it doesn't works on any other one. I tried navigator.isLocallyAvailable : same result. Is there any alternative?

• java time check API

  - by ring bearer

  I am sure this was done 1000 times in 1000 different places. The question is I want to know if there is a better/standard/faster way to check if current "time" is between two time values given in hh:mm:ss format. For example, my big business logic should not run between 18:00:00 and 18:30:00. So here is what I had in mind: public static boolean isCurrentTimeBetween(String starthhmmss, String endhhmmss) throws ParseException{ DateFormat hhmmssFormat = new SimpleDateFormat("yyyyMMddhh:mm:ss"); Date now = new Date(); String yyyMMdd = hhmmssFormat.format(now).substring(0, 8); return(hhmmssFormat.parse(yyyMMdd+starthhmmss).before(now) && hhmmssFormat.parse(yyyMMdd+endhhmmss).after(now)); } Example test case: String doNotRunBetween="18:00:00,18:30:00";//read from props file String[] hhmmss = downTime.split(","); if(isCurrentTimeBetween(hhmmss[0], hhmmss[1])){ System.out.println("NOT OK TO RUN"); }else{ System.out.println("OK TO RUN"); } What I am looking for is code that is better in performance in looks in correctness What I am not looking for third-party libraries Exception handling debate variable naming conventions method modifier issues

• future-proofing java version check in ant script

  - by carneades

  The script provided here gave a great way to check if Ant is using Java 6. <?xml version="1.0" encoding="UTF-8"?> <project name="project" default="default"> <target name="default" depends="javaCheck" if="isJava6"> <echo message="Hello, World!" /> </target> <target name="javaCheck"> <echo message="ant.java.version=${ant.java.version}" /> <condition property="isJava6"> <equals arg1="${ant.java.version}" arg2="1.6" /> </condition> </target> </project> However, I have good reason to think the next person holding my position may not be a Java programmer and I want to make sure the builds don't fail because of Java 7. Is there any way to pick apart a String or otherwise ask for Java 6 or higher?
