  • how do i execute a stored procedure with vici coolstorage?

    - by lincolnk
    I'm building an app around Vici Coolstorage (asp.net version). I have my classes created and mapped to my database tables and can pull a list of all records fine. I've written a stored procedure where the query jumps across databases that aren't mapped with Coolstorage, however, the fields in the query result map directly to one of my classes. The procedure takes 1 parameter. so 2 questions here: how do i execute the stored procedure? i'm doing this CSParameterCollection collection = new CSParameterCollection(); collection.Add("@id", id); var result = Vici.CoolStorage.CSDatabase.RunQuery("procedurename", collection); and getting the exception "Incorrect syntax near 'procedurename'." (i'm guessing this is because it's trying to execute it as text rather than a procedure?) and also, since the class representing my table is defined as abstract, how do i specify that result should create a list of MyTable objects instead of generic or dynamic or whatever objects? if i try Vici.CoolStorage.CSDatabase.RunQuery<MyTable>(...) the compiler yells at me for it being an abstract class.

  • Calling functions from the Immediate Window during debugging -- advanced Visual Studio kung-fu test

    - by kizzx2
    I see some related questions have been asked, but they're either too advanced for me to grasp or lacking a step-by-step guide from start to finish (most of them end up being insider talk of their own experiment results). OK here it is, given this simple program: #include <stdio.h> #include <string.h> int main() { FILE * f; char buffer[100]; memset(buffer, 0, 100); fun(); f = fopen("main.cpp", "r"); fread(buffer, 1, 99, f); printf(buffer); fclose(f); return 0; } What it does is basically print itself (assume file name is main.cpp). Question How can I have it print another file, say foobar.txt without modifying the source code? It has something to do with running it through VS's, stepping through the functions and hijacking the FILE pointer right before fread() is called. No need to worry about leaking resources by calling fclose(). I tried the simple f = fopen("foobar.txt", "r") which gave CXX0017: Error: symbol "fopen" not found Any ideas?

  • Subclassing NSArrayController in order to limit size of arrangedObjects

    - by Simone Manganelli
    I'm trying to limit the number of objects in an array controller, but I still want to be able to access the full array, if necessary. A simple solution I came up with was to subclass NSArrayController, and define a new method named "limitedArrangedObjects", that returns a limited number of objects from the real set of arranged objects. (I've seen http://stackoverflow.com/questions/694493/limiting-the-number-of-objects-in-nsarraycontroller , but that doesn't address my problem.) I want this property to be observable via bindings, so I set a dependency to arrangedObjects on it. Problem is, when arrangedObjects is updated, limitedArrangedObjects seems not to be observing the value change in arrangedObjects. I've hooked up an NSCollectionView to limitedArrangedObjects, and zero objects are being displayed. (If I bind it to arrangedObjects instead, all the objects show up as expected.) What's the problem? Here's the relevant code: @property (readonly) NSArray *limitedArrangedObjects; - (NSArray *)limitedArrangedObjects; { NSArray *arrangedObjects = [super arrangedObjects]; NSUInteger upperLimit = 10000; NSUInteger count = [arrangedObjects count]; if (count > upperLimit) count = upperLimit; arrayToReturn = [arrangedObjects subarrayWithRange:NSMakeRange(0, count)]; return arrayToReturn; } + (NSSet *)keyPathsForValuesAffectingValueForKey:(NSString *)key; { NSSet *keyPaths = [super keyPathsForValuesAffectingValueForKey:key]; if ([key isEqualToString:@"limitedArrangedObjects"]) { NSSet *affectingKeys = [NSSet setWithObjects:@"arrangedObjects",nil]; keyPaths = [keyPaths setByAddingObjectsFromSet:affectingKeys]; } return keyPaths; }

  • Getting identity from Ado.Net Update command

    - by rboarman
    My scenario is simple. I am trying to persist a DataSet and have the identity column filled in so I can add child records. Here's what I've got so far: using (SqlConnection connection = new SqlConnection(connStr)) { SqlDataAdapter adapter = new SqlDataAdapter("select * from assets where 0 = 1", connection); adapter.MissingMappingAction = MissingMappingAction.Passthrough; adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; SqlCommandBuilder cb = new SqlCommandBuilder(adapter); var insertCmd = cb.GetInsertCommand(true); insertCmd.Connection = connection; connection.Open(); adapter.InsertCommand = insertCmd; adapter.InsertCommand.CommandText += "; set ? = SCOPE_IDENTITY()"; adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.OutputParameters; var param = new SqlParameter("RowId", SqlDbType.Int); param.SourceColumn = "RowId"; param.Direction = ParameterDirection.Output; adapter.InsertCommand.Parameters.Add(param); SqlTransaction transaction = connection.BeginTransaction(); insertCmd.Transaction = transaction; try { assetsImported = adapter.Update(dataSet.Tables["Assets"]); transaction.Commit(); } catch (Exception ex) { transaction.Rollback(); // Log an error } connection.Close(); } The first thing that I noticed, besides the fact that the identity value is not making its way back into the DataSet, is that my change to add the scope_identity select statement to the insert command is not being executed. Looking at the query using Profiler, I do not see my addition to the insert command. Questions: 1) Why is my addition to the insert command not making its way to the sql being executed on the database? 2) Is there a simpler way to have my DataSet refreshed with the identity values of the inserted rows? 3) Should I use the OnRowUpdated callback to add my child records? My plan was to loop through the rows after the Update() call and add children as needed. Thank you in advance. Rick

  • Facebook Connect for simple authentication?

    - by Starnzy
    Hi I have an ASP.net website which I want to introduce 'Facebook Connect' functionality into, purely for account login/creation purposes. I want a user to be able to click the 'Login using Facebook' type button, and to then log that user into my website based on a userid lookup from the Facebook response. I have a couple of questions surrounding this: Presumeably I can do all of this using the Facebook API - without the need for an actual pretty public facing 'application' on Facebook? I simply want to utilise the Facebook API for authenticating an account. I'm not interested in creating some app for doing something 'within' facebook itself. I have located some code snippets online and tried using the Facebook Developer Toolkit, calling the getInfo method, and whilst it does come back to my website with a uid, none of the other user information is present within the response, like Email, Name etc. The uid is the only populated field in the response. Here is the code I use: if (ConnectAuthentication.isConnected()) { API api = new API(); api.ApplicationKey = ConnectAuthentication.ApiKey; api.SessionKey = ConnectAuthentication.SessionKey; api.Secret = ConnectAuthentication.SecretKey; api.uid = ConnectAuthentication.UserID; //Display user data captured from the Facebook API. facebook.Schema.user facebookUser = null; try { facebookUser = api.users.getInfo(); User user = new User(); user.FacebookUser = facebookUser; user.IsFacebookUser = true; return user; } catch { return null; } } else { return null; } Can anyone please help with either/both of these queries? Thanks in advance...

  • Question about effective logging in C#

    - by MartyIX
    I've written a simple class for debugging and I call the method Debugger.WriteLine(...) in my code like this: Debugger.WriteLine("[Draw]", "InProgress", "[x,y] = " + x.ToString("0.00") + ", " + y.ToString("0.00") + "; pos = " + lastPosX.ToString() + "x" + lastPosY.ToString() + " -> " + posX.ToString() + "x" + posY.ToString() + "; SS = " + squareSize.ToString() + "; MST = " + startTime.ToString("0.000") + "; Time = " + time.ToString() + phase.ToString(".0000") + "; progress = " + progress.ToString("0.000") + "; step = " + step.ToString() + "; TimeMovementEnd = " + UI.MovementEndTime.ToString()); The body of the procedure Debugger.WriteLine is compiled only in Debug mode (directives #if, #endif). What makes me worry is that I often need ToString() in Debugger.WriteLine call which is costly because it creates still new strings (for changing number for example). How to solve this problem? A few points/questions about debugging/tracing: I don't want to wrap every Debugger.WriteLine in an IF statement or to use preprocessor directives in order to leave out debugging methods because it would inevitable lead to a not very readable code and it requires too much typing. I don't want to use any framework for tracing/debugging. I want to try to program it myself. Are Trace methods (http://msdn.microsoft.com/en-us/library/system.diagnostics.trace.aspx) left out if compiling in release mode? If it is so is it possible that my methods would behave similarly? http://msdn.microsoft.com/en-us/library/fht0f5be.aspx output = String.Format("You are now {0} years old.", years); Which seems nice. Is it a solution for my problem with ToString()?

  • Objective-C basics: subclassing and member variable accessability

    - by Krumelur
    Hi, Code below is pseudo code. Imagine a class "Fruit" which has a factory method to create a fruit. interface Fruit { } +(Fruit*) createFruit: { return [[Fruit alloc] init autorelease]; } Now I want to subclass the Fruit to get an Apple: interface Apple : Fruit { int iSeeds; } +(Apple*) createAppleWithColor: (int) iSeeds { Apple* oApple = [Apple createFruit:]; oApple.iSeeds = iSeeds; return oApple; } Questions: How can I make "iSeeds" private so it cannot be changed from outside? If I add a "private" keyword it does not build anymore. Still I want to set iSeeds from inside my Apple's factory method. I want users allow to READ the content of iSeeds. So I suppose I should have a getter but I can't get it to work. I always get some error about "LValue assignment". The Fruit's createFruit is making use of autorelease. Does the Apple have to reatin/release anything? René

  • Installing RestEasy documentation is not clear--does maven install resteasy?

    - by user798719
    3.1. Standalone Resteasy If you are using resteasy outside of JBoss AS 6, you will need to do a few manual steps to install and configure resteasy. RESTeasy is deployed as a WAR archive and thus depends on a Servlet container. We strongly suggest that you use Maven to build your WAR files as RESTEasy is split into a bunch of different modules. You can see an example Maven project in one of the examples in the examples/ directory Also, when you download RESTeasy and unzip it you will see a lib/ directory that contains the libraries needed by resteasy. Copy these into your /WEB-INF/lib directory. Place your JAX-RS annotated class resources and providers within one or more jars within /WEB-INF/lib or your raw class files within /WEB-INF/classes. Hi, is my confusion justified? I am using JBoss 5 unfortunately. Do I need to download RESTeasy and unzip it IF I am using Maven, as the documentation recommends? Maven grabs all the dependencies that are needed to build a project, including the RESTEasy fraemwork, right? So why the contradiction here? Wish that the documentation would anticipate common questions and be written more clearly.

  • Facebook, Yimg and google-analytics CDNs is freaking me out

    - by Millisami
    Hi, Its been a couple of weeks that some sites just keeps on hanging. e.g. Facebooks = static.ak.fbcdn.net FLicker = l.yimg.com GoogleAnalytics I've googled and found many problems like this and some answers which are outdated or just doesn't solve the problem. I did: Cookies clearing, ran cc cleaner and several other nifty methods. None solved my problem?? Only with facebook, if I enter https:// manually instead of http:// on every url on facebook, it works and when it does the redirection to http://, everytime I have to type 's' on the address bar to make it https:// It is driving me nuts coz I'm developing Facebook App and this problem in being pain in my ass. What might be the reason for these CDNs hanging behaviour?? Update: Mon Feb 8, 2010 Well when I viewed the source with firefox, this is the header part: <link type="text/css" rel="stylesheet" href="http://b.static.ak.fbcdn.net/rsrc.php/zDO0B/hash/8jpbog60.css" /> <link type="text/css" rel="stylesheet" href="http://static.ak.fbcdn.net/rsrc.php/zA96O/hash/8jqnsh63.css" /> <link type="text/css" rel="stylesheet" href="http://b.static.ak.fbcdn.net/rsrc.php/z9X8U/hash/5zy5e7ns.css" /> <link type="text/css" rel="stylesheet" href="http://b.static.ak.fbcdn.net/rsrc.php/z7XWB/hash/b881ctjq.css" /> <link type="text/css" rel="stylesheet" href="http://static.ak.fbcdn.net/rsrc.php/zEMLE/hash/6n3druoq.css" /> <link type="text/css" rel="stylesheet" href="http://b.static.ak.fbcdn.net/rsrc.php/zEEQQ/hash/3et16vbl.css" /> <link type="text/css" rel="stylesheet" href="http://b.static.ak.fbcdn.net/rsrc.php/zF0BN/hash/4ey03a8b.css" /> #<link type="text/css" rel="stylesheet" href="http://b.static.ak.fbcdn.net/rsrc.php/zD46U/hash/4ctxkmr7.css" /> <script type="text/javascript" src="http://b.static.ak.fbcdn.net/rsrc.php/z5KPU/hash/f92tjc5l.js"></script> When I clicked the each link, all links open with its contents except the last link with -# sign prefixed. So the url -#http://b.static.ak.fbcdn.net/rsrc.php/zD46U/hash/4ctxkmr7.css is not opening and this css file is not downloaded and the facebook page looks horrible and all left aligned??

  • NHibernate Child items query using Parent Id

    - by thorkia
    So I have a set up similar to this questions: Parent Child Setup Everything works great when saving the parent and the children. However, I seem to have a problem when selecting the children. I can't seem to get all the children with a specific parent. This fails with: NHibernate.QueryException: could not resolve property: ParentEntity_id of: Test.Data.ChildEntity Here is my code: public IEnumerable<ChildEntity> GetByParent(ParentEntity parent) { using (ISession session = OrmHelper.OpenSession()) { return session.CreateCriteria<ChildEntity>().Add(Restrictions.Eq("ParentEntity_id ", parent.Id)).List<ChildEntity>(); } } Any help in building a proper function to get all the items would be appreciated. Oh, I am using Fluent NHibernate to construct the mappings - version 1 RTM and NHibernate 2.1.2 GA If you need more information, let me know. As per you request, my fluent mappings: public ParentEntityMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Code).UniqueKey("ukCode"); HasMany(x => x.ChildEntity).LazyLoad() .Inverse().Cascade.SaveUpdate(); } public ChildEntityMap() { Id(x => x.Id); Map(x => x.Amount); Map(x => x.LogTime); References(x => x.ParentEntity); } That maps to the following 2 tables: CREATE TABLE "ParentEntity" ( Id integer, Name TEXT, Code TEXT, primary key (Id), unique (Code) ) CREATE TABLE "ChildEntity" ( Id integer, Amount NUMERIC, LogTime DATETIME, ParentEntity_id INTEGER, primary key (Id) ) The data store in SQLite.

  • Storing an object to use in multiple classes

    - by Aaron Sanders
    I am wondering the best way to store an object in memory that is used in a lot of classes throughout an application. Let me set up my problem for you: We have multiple databases, 1 per customer. We also have a master table and each row is detailed information about the databases such as database name, server IP it's located and a few config settings. I have an application that loops through those multiple databases and runs some updates on them. The settings I mentioned above are updated each loop iteration into memory. The application then runs through series of processes that include multiple classes using this data. The data never changes during the processes, only during the loop iteration. The variables are related to a customer, so I have them stored in a customer class. I suppose I could make all of the members shared or should I use a singleton for the customer class? I've never actually used a singleton, only read they are good in this type of situation. Are there better solutions to this type of scenario? Also, I could have plans for this application to be multithreaded later. Sorry if this is confusing. If you have questions, let me know and I will answer them. Thanks for your help.

  • Design Question - how do you break the dependency between classes using an interface?

    - by Seth Spearman
    Hello, I apologize in advance but this will be a long question. I'm stuck. I am trying to learn unit testing, C#, and design patterns - all at once. (Maybe that's my problem.) As such I am reading the Art of Unit Testing (Osherove), and Clean Code (Martin), and Head First Design Patterns (O'Reilly). I am just now beginning to understand delegates and events (which you would see if you were to troll my SO questions of recent). I still don't quite get lambdas. To contextualize all of this I have given myself a learning project I am calling goAlarms. I have an Alarm class with members you'd expect (NextAlarmTime, Name, AlarmGroup, Event Trigger etc.) I wanted the "Timer" of the alarm to be extensible so I created an IAlarmScheduler interface as follows... public interface AlarmScheduler { Dictionary<string,Alarm> AlarmList { get; } void Startup(); void Shutdown(); void AddTrigger(string triggerName, string groupName, Alarm alarm); void RemoveTrigger(string triggerName); void PauseTrigger(string triggerName); void ResumeTrigger(string triggerName); void PauseTriggerGroup(string groupName); void ResumeTriggerGroup(string groupName); void SetSnoozeTrigger(string triggerName, int duration); void SetNextOccurrence (string triggerName, DateTime nextOccurrence); } This IAlarmScheduler interface define a component that will RAISE an alarm (Trigger) which will bubble up to my Alarm class and raise the Trigger Event of the alarm itself. It is essentially the "Timer" component. I have found that the Quartz.net component is perfectly suited for this so I have created a QuartzAlarmScheduler class which implements IAlarmScheduler. All that is fine. My problem is that the Alarm class is abstract and I want to create a lot of different KINDS of alarm. For example, I already have a Heartbeat alarm (triggered every (int) interval of minutes), AppointmentAlarm (triggered on set date and time), Daily Alarm (triggered every day at X) and perhaps others. And Quartz.NET is perfectly suited to handle this. My problem is a design problem. I want to be able to instantiate an alarm of any kind without my Alarm class (or any derived classes) knowing anything about Quartz. The problem is that Quartz has awesome factories that return just the right setup for the Triggers that will be needed by my Alarm classes. So, for example, I can get a Quartz trigger by using TriggerUtils.MakeMinutelyTrigger to create a trigger for the heartbeat alarm described above. Or TriggerUtils.MakeDailyTrigger for the daily alarm. I guess I could sum it up this way. Indirectly or directly I want my alarm classes to be able to consume the TriggerUtils.Make* classes without knowing anything about them. I know that is a contradiction, but that is why I am asking the question. I thought about putting a delegate field into the alarm which would be assigned one of these Make method but by doing that I am creating a hard dependency between alarm and Quartz which I want to avoid for both unit testing purposes and design purposes. I thought of using a switch for the type in QuartzAlarmScheduler per here but I know it is bad design and I am trying to learn good design. If I may editorialize a bit. I've decided that coding (predefined) classes is easy. Design is HARD...in fact, really hard and I am really fighting feeling stupid right now. I guess I want to know if you really smart people took a while to really understand and master this stuff or should I feel stupid (as I do) because I haven't grasped it better in the couple of weeks/months I have been studying. You guys are awesome and thanks in advance for your answers. Seth

  • How to disable mod_security2 rule (false positive) for one domain on centos 5

    - by nicholas.alipaz
    Hi I have mod_security enabled on a centos5 server and one of the rules is keeping a user from posting some text on a form. The text is legitimate but it has the words 'create' and an html <table> tag later in it so it is causing a false positive. The error I am receiving is below: [Sun Apr 25 20:36:53 2010] [error] [client 76.171.171.xxx] ModSecurity: Access denied with code 500 (phase 2). Pattern match "((alter|create|drop)[[:space:]]+(column|database|procedure|table)|delete[[:space:]]+from|update.+set.+=)" at ARGS:body. [file "/usr/local/apache/conf/modsec2.user.conf"] [line "352"] [id "300015"] [rev "1"] [msg "Generic SQL injection protection"] [severity "CRITICAL"] [hostname "www.mysite.com"] [uri "/node/181/edit"] [unique_id "@TaVDEWnlusAABQv9@oAAAAD"] and here is /usr/local/apache/conf/modsec2.user.conf (line 352) #Generic SQL sigs SecRule ARGS "((alter|create|drop)[[:space:]]+(column|database|procedure|table)|delete[[:space:]]+from|update.+set.+=)" "id:1,rev:1,severity:2,msg:'Generic SQL injection protection'" The questions I have are: What should I do to "whitelist" or allow this rule to get through? What file do I create and where? How should I alter this rule? Can I set it to only be allowed for the one domain, since it is the only one having the issue on this dedicated server or is there a better way to exclude table tags perhaps? Thanks guys

  • Building/Testing a Universal iPhone/iPad application

    - by psychotik
    I have a project configured (I think) to produce Universal binaries. The base SDK is set to 3.2 and the Deployment Target is set to 3.1. Target Device Family is iPhone/iPad and the architecture is armv6 armv7. I had a few questions about how this Universal binary thing really works: 1) When I want to submit an app binary for review, what configuration should I set as the build target? If I set it as "Device - 3.1" I get a warning which says "warning: building with Targeted Device Family" that includes iPad('1,2') requires building with the 3.2 or later SDK". However, if I build with SDK 3.2, will it still run on iPhones with OS 3.1? What's the right configuration for device and architecture (arm6/arm7)? 2) How do I test the scenario above (built with SDK 3.2, but installed on a device running OS 3.1)? If I build with SDK 3.2, when I try to install it on a phone with OS 3.1, I get an error saying that the phone's OS isn't updated. Thanks!

  • C++ classes with members referencing each other

    - by Saad Imran.
    I'm trying to write 2 classes with members that reference each other. I'm not sure if I'm doing something wrong or it's just not possible. Can anyone help me out here... Source.cpp #include "Headers.h" using namespace std; void main() { Network* network = new Network(); system("pause"); return; } Headers.h #ifndef Headers_h #define Headers_h #include <iostream> #include <vector> #include "Network.h" #include "Router.h" #endif Network.h #include "Headers.h" class Network { protected: vector<Router> Routers; }; Router.h #include "Headers.h" class Router { protected: Network* network; public: }; The errors I'm getting are: error C2143: syntax error : missing ';' before '<' error C2238: unexpected token(s) preceding ';' error C4430: missing type specifier - int assumed. I'm pretty sure I'm not missing any semicolons or stuff like that. The program works find if I take out one of the members. I tried finding similar questions and the solution was to use pointers, but that's what I'm doing and it does't seem to be working!

  • Porting WebGL game to iPhone's native OpenGL?

    - by ArtPulse
    We are developing a web game that uses WebGL for the two biggest parts of it. Working with HTML / CSS was too slow and too limited, so it's off the table. Thing is, iOS does not support WebGL publicly just yet, only on iAd. It is my guess Apple will eventually support it once the security issues they and Microsoft claim it has are fixed, and looks stable enough. Problem is, if Apple does not do this by the release of the next mayor iOS version, then we will have in our hands a mobile WebGL game that does not run. 6 months of development and testing to waste. So, questions: If that was the case, how viable (regarding amount of time) is it porting the WebGL part of the game to native iPhone OpenGL? I'm afraid that porting will take longer than the development of the game itself. I saw posts on Stack Overflow (like this) that suggested, on Android, adding the OpenGL interface manually to a WebKit element. It'd be slower than native. But either way... Is this something that could be accepted in the AppStore? Apple is very restrictive with these kind of stuff... Thank you all for your time!

    Hi I've read similar questions regarding that but still feel the need to ask a question. I have scenario where we have lots of tiny "features" pending for approval. I generally see two approaches. 1.Keep trunk solid and have tons of branches for each tiny "feature". Basically every new thingy is a branch. Cons: - Might become nightmare to support so many branches no matter how small a change. Keeping all branches in sync etc etc. - Worst con I see in this is setup of test system so one can easily examine changes to approve (basically need to support all branches which seems insane). Pros: - Seemningly easy once approved a branch to be merged back to trunk and new release to be tagged and deployed. 2.For big features a branch is released and for small changes all goes in trunk(relatively stable) directly. Pros: - Easier to set test system as most of the time all will be directly visible. For big features should be easy to maintain separate branch on test. Cons: - Don't really see how release will go. I will not be able to basically release one part of trunk This would involve cherrypicking which is crazy to follow. Other approach is I just enforce that after some time (a week or so) all small features need to be approved so they can deployed before giving new tasks. I just create release branch and either all or none of small features are going live. This will be some fun discussion with head people. I guess having lots of small pending stuff is very problematic to follow technically.

  • find and replace values in a flat-file using PHP

    - by peirix
    I'd think there was a question on this already, but I can't find one. Maybe the solution is too easy... Anyway, I have a flat-file and want to let the user change the values based on a name. I've already sorted out creating new name+value-pairs using the fopen('a') mode, using jQuery to send the AJAX call with newValue and newName. But say the content looks like this: host|http:www.stackoverflow.com folder|/questions/ folder2|/users/ And now I want to change the folder value. So I'll send in folder as oldName and /tags/ as newValue. What's the best way to overwrite the value? The order in the list doesn't matter, and the name will always be on the left, followed by a |(pipe), the value and then a new-line. My first thought was to read the list, store it in an array, search all the [0]'s for oldName, then change the [1] that belongs to it, and then write it back to a file. But I feel there is a better way around this? Any ideas? Maybe regex?

  • How to position an element next to another an element of undefined position?

    - by allin
    Hi, I am very new to html/xml/css and I'm trying my best to teach myself. However, I have run into a problem that a Google search could not solve. I would like to position a small image in a fixed location relative to another element(?) I believe this is the code of the element i want to position the second element relative to. #wrap { width:550px; background-color:#fff; margin:0 auto; padding:0; border-right:1px solid #ccc; border-left:1px solid #ccc; } #container { width: 500px; margin:0 auto; padding: 25px; font-size:.85em; background-color: #fff; } and this is partial code I'm trying to edit to position .xyz to the right of "#wrap" .xyz { position: ???; top: 200px; right: ???; _position: ???; _margin: ???; _text-align: right; z-index: 1337; } my search of SOF has lead me to believe i'm supposed to do something along the lines of this - http://stackoverflow.com/questions/104953/position-an-html-element-relative-to-its-container-using-css - but i haven't been able to. I greatly appreciate any help you may offer. Hopefully I've explained my problem properly.

    hi expert, i'm having task to scan wifi at specific interval and send it to the server, i've it in python and its works fine when i run manually, then build it to package and when run there is no progress at all, i already ask this question before at http://stackoverflow.com/questions/2735410/python-scritp-problem-once-build-and-package-it, then, i re-modify my code as below, then i found that thread is not functioning once i build, #!/usr/bin/env python import subprocess,threading,... configFile = open('/opt/Jemapoh_Wifi/config.txt', 'r') url = configFile.readline().strip() intervalTime = configFile.readline().strip() status = configFile.readline().strip() print "url "+url print "intervalTime "+intervalTime print "Status "+status.strip() def getMacAddress(): proc = subprocess.Popen('ifconfig -a wlan0 | grep HWaddr | sed \'/^.*HWaddr */!d; s///;q\'', shell=True, stdout=subprocess.PIPE, ) macAddress = proc.communicate()[0].strip() return macAddress def getTimestamp(): from time import strftime timeStamp = strftime("%Y-%m-%d %H:%M:%S") return timeStamp def scanWifi(): try: print "Scanning..." proc = subprocess.Popen('iwlist scan 2>/dev/null', shell=True, stdout=subprocess.PIPE, ) stdout_str = proc.communicate()[0] stdout_list=stdout_str.split('\n') essid=[] rssi=[] preQuality=[] for line in stdout_list: line=line.strip() match=re.search('ESSID:"(\S+)"',line) if match: essid.append(match.group(1)) match=re.search('Quality=(\S+)',line) if match: preQuality.append(match.group(1)) for qualityConversion in preQuality: qualityConversion = qualityConversion.split()[0].split('/') temp = str(int(round(float(qualityConversion[0]) / float(qualityConversion[1]) * 100))).rjust(2) rssi.append(temp) dataToPost = '{"userId":"' + getMacAddress() + '","timestamp":"' + getTimestamp() + '","wifi":[' for no in range(len(essid)): dataToPost += '{"ssid":"' + essid[no] + '","rssi":"' + rssi[no] + '"}' if no+1 == len(essid): pass else: dataToPost += ',' dataToPost += ']}' query_args = {"data":dataToPost} request = urllib2.Request(url) request.add_data(urllib.urlencode(query_args)) request.add_header('Content-Type', 'application/x-www-form-urlencoded') print "Waiting for server response..." print urllib2.urlopen(request).read() print "Data Sent @ " + getTimestamp() print "------------------------------------------------------" t = threading.Timer(int(intervalTime), scanWifi).start() except Exception, e: print e t = threading.Timer(int(intervalTime), scanWifi) t.start() once build, its not reaching the thread, do can anyone help, why the thread is not working after build thanks

  • How to generate an ear file from a maven-archetype-webapp artifact?

    - by Mike
    I currently have a project built with maven-archetype-webapp artifact. The default packaging for this project is war. Is it possible for me to insert the maven-ear-plugin in this webapp pom.xml generate an ear file that contains this project war? I tried that, but the war file doesn't get embedded in the generated ear file. It has everything except the war file. I read many Maven related articles, and perhaps I could use maven-archetype-j2ee-simple artifact. However, I'm reluctant to this use for 2 reasons:- This artifact handles ejbs and all the extra features that I don't use. It makes my project looks bloated. Second, it seems like it requires me to install the web module into the repository first before I can create the ear file. Is this the preferred way to create an ear file? How do I create an ear file that contains the war file using maven-ear-plugin from my webapp's pom.xml? If this way is not possible, what's the preferred way? I'm sorry if my questions sound a little novice, I realized I have whole lot more to learn about Maven. Thanks much.

  • Optimal two variable linear regression SQL statement (censoring outliers)

    - by Dave Jarvis
    Problem Am looking to apply the y = mx + b equation (where m is SLOPE, b is INTERCEPT) to a data set, which is retrieved as shown in the SQL code. The values from the (MySQL) query are: SLOPE = 0.0276653965651912 INTERCEPT = -57.2338357550468 SQL Code SELECT ((sum(t.YEAR) * sum(t.AMOUNT)) - (count(1) * sum(t.YEAR * t.AMOUNT))) / (power(sum(t.YEAR), 2) - count(1) * sum(power(t.YEAR, 2))) as SLOPE, ((sum( t.YEAR ) * sum( t.YEAR * t.AMOUNT )) - (sum( t.AMOUNT ) * sum(power(t.YEAR, 2)))) / (power(sum(t.YEAR), 2) - count(1) * sum(power(t.YEAR, 2))) as INTERCEPT FROM (SELECT D.AMOUNT, Y.YEAR FROM CITY C, STATION S, YEAR_REF Y, MONTH_REF M, DAILY D WHERE -- For a specific city ... -- C.ID = 8590 AND -- Find all the stations within a 15 unit radius ... -- SQRT( POW( C.LATITUDE - S.LATITUDE, 2 ) + POW( C.LONGITUDE - S.LONGITUDE, 2 ) ) <15 AND -- Gather all known years for that station ... -- S.STATION_DISTRICT_ID = Y.STATION_DISTRICT_ID AND -- The data before 1900 is shaky; insufficient after 2009. -- Y.YEAR BETWEEN 1900 AND 2009 AND -- Filtered by all known months ... -- M.YEAR_REF_ID = Y.ID AND -- Whittled down by category ... -- M.CATEGORY_ID = '001' AND -- Into the valid daily climate data. -- M.ID = D.MONTH_REF_ID AND D.DAILY_FLAG_ID <> 'M' GROUP BY Y.YEAR ORDER BY Y.YEAR ) t Data The data is visualized here (with five outliers highlighted): Questions How do I return the y value against all rows without repeating the same query to collect and collate the data? That is, how do I "reuse" the list of t values? How would you change the query to eliminate outliers (at an 85% confidence interval)? The following results (to calculate the start and end points of the line) appear incorrect. Why are the results off by ~10 degrees (e.g., outliers skewing the data)? (1900 * 0.0276653965651912) + (-57.2338357550468) = -4.66958228 (2009 * 0.0276653965651912) + (-57.2338357550468) = -1.65405406 I would have expected the 1900 result to be around 10 (not -4.67) and the 2009 result to be around 11.50 (not -1.65). Thank you!

  • In WMI, can I use a join (or something similar) to acquire the IisWebServer object for a site, given

    - by Precipitous
    Given a server name and a physical path, I'd like to be able to hunt down the IISWebServer object and ApplicationPool. Website url is also an acceptable input. Our technologies are IIS 6, WMI, and access via C# or Powershell 2. I'm certain this would be easier with IIS 7 its managed API. We don't have that yet. Here's what I can do: Get a list of IIS virtual directories from IISWebVirtualDirSetting and filter (offline) for the matching physical path. $theVirtualDir = gwmi -Namespace "root/MicrosoftIISv2" ` -ComputerName $servername -authentication PacketPrivacy ` -class "IISWebVirtualDirSetting" ` | where-object {$_.Path -like $deployLocation} From the virtual directory object, I can get a name (like W3SVC/40565456/root). Given this name, I can get to other goodies, such as the IIS web server object. gwmi -Namespace "root/MicrosoftIISv2" ` -ComputerName $servername ` -authentication PacketPrivacy ` -Query "SELECT * FROM IisWebServer WHERE Name='W3SVC/40589473'" The questions, restated: 1) This is a query language. Can I join or subquery so that 1 WMI query statement gets web servers based on IISWebVirtualDir.Path? How? 2) In solving 1, you'll have to explain how to query on the Path property. Why is this an invalid query? "SELECT * FROM IISWebVirtualDirSetting WHERE Path='D:\sites\globaldominator'"

  • What header file is where the boost libray define its own primitive data type?

    - by ronghai
    Recently, I try to use the boost::spirit::qi binary endian parser to parse some binary data depends on the endianness of the Platform. There is a simple example, like following: Using declarations and variables: using boost::spirit::qi::little_word; using boost::spirit::qi::little_dword; using boost::spirit::qi::little_qword; boost::uint16_t us; boost::uint32_t ui; boost::uint64_t ul; Basic usage of the little endian binary parsers: test_parser_attr("\x01\x02", little_word, us); assert(us == 0x0201); test_parser_attr("\x01\x02\x03\x04", little_dword, ui); assert(ui == 0x04030201); test_parser_attr("\x01\x02\x03\x04\x05\x06\x07\x08", little_qword, ul); assert(ul == 0x0807060504030201LL); test_parser("\x01\x02", little_word(0x0201)); test_parser("\x01\x02\x03\x04", little_dword(0x04030201)); test_parser("\x01\x02\x03\x04\x05\x06\x07\x08", little_qword(0x0807060504030201LL)); It works very well. But my questions come, why do we need use some data types like boost::uint16_t, boost::uint32_t here? Can I use unsigned long or unsigned int here? And if I want to parse double or float data type, what boost data type should I use? And please tell me where is boost define the above these types? Thanks a lot.
