  • Custom jQuery dropdown

    - by Coughlin
    I am creating a custom simple dropdown using jQuery that hides/shows a element based on over state. The problem I have now is that when you go over the shown element it hides, you cant move your mouse in to the dropdown that was created. Any thoughts on how to fix that also, is there an easier way to do what I have? I am going to be reusing this and not sure the best way to set the code up for I dont need to copy/paste six times. $(function(){ $("#dog-nav").hover( function(){ $(".sub-drop-box-dog").show("fast"); }, function(){ $(".sub-drop-box-dog").hide("fast"); } ); $("#cat-nav").hover( function(){ $(".sub-drop-box-cat").show("fast"); }, function(){ $(".sub-drop-box-cat").hide("fast"); } ); });

  • Is my form password being passed in clear text?

    - by liinkas
    This is what my browser sent, when logging into some site: POST http://www.some.site/login.php HTTP/1.0 User-Agent: Opera/8.26 (X2000; Linux i686; Z; en) Host: www.some.site Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 Accept-Language: en-US,en;q=0.9 Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1 Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 Referer: http://www.some.site/ Proxy-Connection: close Content-Length: 123 Content-Type: application/x-www-form-urlencoded lots_of_stuff=here&e2ad811=my_login_name&e327696=my_password&lots_of_stuff=here Can I state that anyone can sniff my login name and password for that site? Maybe just on my LAN? If so (even only on LAN ) then I'm shocked. I thought using <input type="password"> did something more than make all characters look like ' * ' p.s. If it matters I played with netcat (on linux) and made connection browser <= netcat (loged here) <= proxy <= remote_site

  • Dynamically call a stored procedure from another stored procedure

    - by Greg
    I want to be able to pass in the name of a stored procedure as a string into another stored procedure and have it called with dynamic parameters. I'm getting an error though. Specifically I've tried: create procedure test @var1 varchar(255), @var2 varchar(255) as select 1 create procedure call_it @proc_name varchar(255) as declare @sp_str varchar(255) set @sp_str = @proc_name + ' ''a'',''b''' print @sp_str exec @sp_str exec call_it 'test' So procedure call_it should call procedure test with arguments 'a', and 'b'. When I run the above code I get: Msg 2812, Level 16, State 62, Procedure call_it, Line 6 Could not find stored procedure 'test 'a','b''. However, running test 'a','b' works fine.

  • Windows API GUI programming

    - by genesys
    Hi! I'm working on a Project with outdated, very old looking GUI (the used GUI framework is more than 10 years old) Since the used programming language is Eiffel, there are almost no good libraries for GUI development. Although Wrappers for C libraries exist, it's not that easy to wrap something like Qt with them. The current GUI framework uses the Windows API to create windows, widgets and so on. But as stated - it's very old. Now i would like to learn more about how to use the Windows API directly to create state of the art GUI's Can someone recommend any reading material? Thanks!

  • What are the best options for a root filesystem hosted on SSD under Linux

    - by stsquad
    I'm working on an embedded system which is going to be booting and hosting it's rootfs on an SSD disk. We are currently looking at using Intel X-18M SSDs. The file system structure will have a fairly static /usr section (modulo software upgrades) and an active /var and /var/log for maintaining state and logging. Given the wear-levelling done by the underlying flash does having separate partitions help or hinder? As modern SSDs appear as straight block devices and hide their mapping magic behind their firmware is there any point trying to optimise the choice of file-system that sits on-top of the SSD? Finally does enable SMART monitoring make any sense in this context or are their SSD specific ways of determining the underlying health of the storage hardware?

  • Client/JS Framework for "Unsaved Data" Protection?

    - by Kevin Dostalek
    Hey all- we have a typical web application that is essentially a data entry application with lots of screens some of which have some degree of complexity. We need to provide that standard capability on making sure if the user forgets to click the "Save" button before navigating away or closing their browser they get a warning and can cancel (but only when there is unsaved or dirty data). I know the basics of what I've got to do-- in fact I'm sure I've done it all before over the years (tie in to onbeforeunload, track the "dirty" state of the page, etc...) but before I embark on coding this YET AGAIN, does anyone have some suggestions for libraries already out there (free or otherwise) that will help out? Thanks!

  • rubyCAS-client serviceValidation uri questions.

  • Check if serial port is listening

    - by Hyposaurus
    I have an Arduino sending and receiving instructions with a python script via a serial port. The Arduino takes a button state and when it is pushed it will send a message via serial to a python script and await a response. (via Serial.available()). Works well enough. However if the python script has crashed for whatever reason (ideally it will run in the background, so cant be easily checked) the Arduino will wait forever and even on a script restart will we unavailable. Is there a way for my Arduino to check if there is something listening on the serial port? (and alert me with flashing lights etc if not) or is this not how serial works? Worst case I guess I could use a timeout, although that is not ideal.

  • Watching a variable for changes without polling.

    - by milkfilk
    I'm using a framework called Processing which is basically a Java applet. It has the ability to do key events because Applet can. You can also roll your own callbacks of sorts into the parent. I'm not doing that right now and maybe that's the solution. For now, I'm looking for a more POJO solution. So I wrote some examples to illustrate my question. Please ignore using key events on the command line (console). Certainly this would be a very clean solution but it's not possible on the command line and my actual app isn't a command line app. In fact, a key event would be a good solution for me but I'm trying to understand events and polling beyond just keyboard specific problems. Both these examples flip a boolean. When the boolean flips, I want to fire something once. I could wrap the boolean in an Object so if the Object changes, I could fire an event too. I just don't want to poll with an if() statement unnecessarily. import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; /* * Example of checking a variable for changes. * Uses dumb if() and polls continuously. */ public class NotAvoidingPolling { public static void main(String[] args) { boolean typedA = false; String input = ""; System.out.println("Type 'a' please."); while (true) { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader br = new BufferedReader(isr); try { input = br.readLine(); } catch (IOException ioException) { System.out.println("IO Error."); System.exit(1); } // contrived state change logic if (input.equals("a")) { typedA = true; } else { typedA = false; } // problem: this is polling. if (typedA) System.out.println("Typed 'a'."); } } } Running this outputs: Type 'a' please. a Typed 'a'. On some forums people suggested using an Observer. And although this decouples the event handler from class being observed, I still have an if() on a forever loop. import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.Observable; import java.util.Observer; /* * Example of checking a variable for changes. * This uses an observer to decouple the handler feedback * out of the main() but still is polling. */ public class ObserverStillPolling { boolean typedA = false; public static void main(String[] args) { // this ObserverStillPolling o = new ObserverStillPolling(); final MyEvent myEvent = new MyEvent(o); final MyHandler myHandler = new MyHandler(); myEvent.addObserver(myHandler); // subscribe // watch for event forever Thread thread = new Thread(myEvent); thread.start(); System.out.println("Type 'a' please."); String input = ""; while (true) { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader br = new BufferedReader(isr); try { input = br.readLine(); } catch (IOException ioException) { System.out.println("IO Error."); System.exit(1); } // contrived state change logic // but it's decoupled now because there's no handler here. if (input.equals("a")) { o.typedA = true; } } } } class MyEvent extends Observable implements Runnable { // boolean typedA; ObserverStillPolling o; public MyEvent(ObserverStillPolling o) { this.o = o; } public void run() { // watch the main forever while (true) { // event fire if (this.o.typedA) { setChanged(); // in reality, you'd pass something more useful notifyObservers("You just typed 'a'."); // reset this.o.typedA = false; } } } } class MyHandler implements Observer { public void update(Observable obj, Object arg) { // handle event if (arg instanceof String) { System.out.println("We received:" + (String) arg); } } } Running this outputs: Type 'a' please. a We received:You just typed 'a'. I'd be ok if the if() was a NOOP on the CPU. But it's really comparing every pass. I see real CPU load. This is as bad as polling. I can maybe throttle it back with a sleep or compare the elapsed time since last update but this is not event driven. It's just less polling. So how can I do this smarter? How can I watch a POJO for changes without polling? In C# there seems to be something interesting called properties. I'm not a C# guy so maybe this isn't as magical as I think. private void SendPropertyChanging(string property) { if (this.PropertyChanging != null) { this.PropertyChanging(this, new PropertyChangingEventArgs(property)); } }

  • How should I use random.jumpahead in Python

    - by Peter Smit
    I have a application that does a certain experiment 1000 times (multi-threaded, so that multiple experiments are done at the same time). Every experiment needs appr. 50.000 random.random() calls. What is the best approach to get this really random. I could copy a random object to every experiment and do than a jumpahead of 50.000 * expid. The documentation suggests that jumpahead(1) already scrambles the state, but is that really true? Or is there another way to do this in 'the best way'? (No, the random numbers are not used for security, but for a metropolis hasting algorithm. The only requirement is that the experiments are independent, not whether the random sequence is somehow predictable or so)

  • How can I programmatically find the IP address/netmask/gateway configured for a specific network dev

    - by Oren S
    Hi I would like to write a piece of code which checks, for each network device (e.g. eth0, lo, master devices) some statistics and configuration data about that device. I could find the statistics data (and most of the configuration data) in /sys/class/net/..., however, I couldn't find any C/C++ API or any entry in procfs/sysfs listing the inet addr, netmask and gateway. Some alternatives I checked: parsing the output from ifconfig/route/some other utilities: I don't want to start a subprocess every time I need to do the inspection. parsing /etc/sysconfig/network-scripts/: will give me only the start-up configuration, and not the current state. Also, since this code is intended for a product in my workplace, where every external library is inspected thoroughly (meaning it will take me forever to add any external library) I prefer solutions which rely on Linux native API and not external libraries. Thanks!

  • Macros no longer working in VS2005

    - by NPVN
    I'm using VS2005 on Vista. I'm using some macros, but now they have suddenly stopped working. No error messages of any kind. I am not aware of having done anything that could trigger this. I have made sure that "Allow macros to run" is checked in Tools-Options-Addin/Macro Security. I have tried running the macros from a keyboard shortcut, from the Macro Explorer, and from the Macros IDE, all in vain: The little spinning icon displays shortly (<1 sec) and then disappears without the macro being executed. I have tried putting a breakpoint on the first line of the macro and then executing it from the main IDE, with no effect (the breakpoint isn't hit). I have tried the same from the Macro IDE: The state changes to "running", but the breakpoint isn't hit. I have to break the execution manually. Any ideas?

  • language to create flowcharts

    - by robintw
    Hi, This seems like something which must have been answered before, but I can't find anything appropriate in the question archives. Basically, I'm looking for a little Domain Specific Language to create flowcharts. I'm terrible at graphic design and making things look nice, and I'd really like a langauge where I could write something in code and it would produce a pretty flowchart. I've come across GraphViz, but it seems more suited to creating things like Finite State Machine diagrams, rather than process flowcharts. It also doesn't have the simple DSL-style front-end that would allow me to easily work it. Any ideas? I'm sure this must have been done before... Robin

  • Oracle: show parameters on error

    - by llappall
    When Oracle logs a parameterized SQL query failing, it shows "?" in place of the parameters, i.e. the query before replacing parameters. For example, "SELECT * FROM table where col like '?'" SQL state [99999]; error code [29902]; ORA-29902: error in executing ODCIIndexStart() routine ORA-20000: Oracle Text error: DRG-50901: text query parser syntax error on line 1, column 48 Is there a way to change logging so it shows the parameter values? The information above is absolutely useless unless I can see what the actual parsing problem was. In general, is there a way to set logs in Oracle to show parameters in parameterized query errors?

  • Flash causing jerky javascript animations

    - by Matt Brailsford
    Hi Guys, I'm developing a site which has a flash background playing a small video loop scaled to fill the whole background. Over the top I have a number of HTML elements which are animated using javascript. The problem I am having is that (predominantly in FF, but also in others to a lesser degree) the flash seems to be causing my javascript animations to run rather jerky, and in some cases missing the animation altogether and just jumping to the end state. Does anybody have any thoughts on how to make the 2 work together nicely? Many thanks Matt

  • Best way to store sales tax information

    - by Seph
    When designing a stock management database system (sales / purchases) what would be the best way to store the various taxes and other such amounts? A few of the fields that could be saved are: Unit price excluding tax Unit price including tax Tax per item Total excluding tax (rounded to 2 decimals) Total including tax (rounded to 2 decimals) Total tax (rounded to 2 decimals) Currently the most reasonable solution so far is storing down (roughly) item, quantity, total excluding tax (rounded) and the total tax (rounded). Can anyone suggest some better way of storing this details for a generic system? Also, given the system needs to be robust, what should be done if there were multiple tax values (eg: state and city) which might need to be separated, in this case a separate table would be in order, but would it be considered excessive to just have a rowID and some taxID mapping to a totalTax column?

  • versioning fails for onetomany collection holder

    - by Alexander Vasiljev
    given parent entity @Entity public class Expenditure implements Serializable { ... @OneToMany(mappedBy = "expenditure", cascade = CascadeType.ALL, orphanRemoval = true) @OrderBy() private List<ExpenditurePeriod> periods = new ArrayList<ExpenditurePeriod>(); @Version private Integer version = 0; ... } and child one @Entity public class ExpenditurePeriod implements Serializable { ... @ManyToOne @JoinColumn(name="expenditure_id", nullable = false) private Expenditure expenditure; ... } While updating both parent and child in one transaction, org.hibernate.StaleObjectStateException is thrown: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): Indeed, hibernate issues two sql updates: one changing parent properties and another changing child properties. Do you know a way to get rid of parent update changing child? The update results both in inefficiency and false positive for optimistic lock. Note, that both child and parent save their state in DB correctly. Hibernate version is 3.5.1-Final

  • How to call an extended procedure from a function

    - by Alan Featherston Lago
    hi im having trouble trying to get the following function to work. CREATE FUNCTION test ( @nt_group VARCHAR(128) ) RETURNS @nt_usr TABLE ( [name] [nchar](128) NULL , [type] [char](8) NULL , [privilege] [char](9) NULL , [mapped login name] [nchar](128) NULL , [permission path] [nchar](128) NULL ) AS BEGIN INSERT INTO @nt_usr EXEC master.dbo.xp_logininfo 'DOMAIN\USER', @nt_group RETURN END As far as i know i should be allowed to call an extended stored procedure, im getting the following error Mes 443, Level 16, State 14 Could it be that xp_logininfo might return different result sets depending on the parameters? When i use openquery i can overcome this by setting this: SET FMTONLY OFF. Does anyone know if there's a similar workaround for my problem?

  • Insert multiple values using INSERT INTO

    - by Ben McCormack
    In SQL Server 2005, I'm trying to figure out why I'm not able to insert multiple fields into a table. The following query, which inserts one record, works fine: INSERT INTO [MyDB].[dbo].[MyTable] ([FieldID] ,[Description]) VALUES (1000,N'test') However, the following query, which specifies more than one value, fails: INSERT INTO [MyDB].[dbo].[MyTable] ([FieldID] ,[Description]) VALUES (1000,N'test'),(1001,N'test2') I get this message: Msg 102, Level 15, State 1, Line 5 Incorrect syntax near ','. When I looked up the help for INSERT in SQL Sever Management Studio, one of their examples showed using the "Values" syntax that I used (with groups of values in parentheses and separated by commas). The help documentation I found in SQL Server Management Studio looks like it's for SQL Server 2008, so perhaps that's the reason that the insert doesn't work. Either way, I can't figure out why it won't work.

  • How to create a bold and italic label in MFC?

    - by Hamish Grubijan
    Please do not mark it as a dupe of this question just yet: http://stackoverflow.com/questions/1881865/bold-labels-in-mfc That question does not help me; for some reason I do not see the rich edit control. Instead I believe I have to do it in code. here is a sample I found: http://www.tech-archive.net/Archive/VC/microsoft.public.vc.mfc/2006-10/msg00245.html My problem is that I prefer not to re-invent the wheel and test for errors myself or through QA. Someone must have implemented this before. Please share your code. What I would like to do is: Keep the same font size, family, etc. as in the already created label, but make it bold and italic as well. Keep the memory footprint reasonably low (do not create any new unnecessary objects), but do not get the app into an inconsistent state either. I appreciate your help.

  • How do I test ActionFilterAttributes that work with ModelState?

    - by Tomas Lycken
    As suggested by (among others) Kazi Manzur Rashid in this blog post, I am using ActionFilterAttributes to transfer model state from one request to another when redirecting. However, I find myself unable to write a unit test that test the behavior of these attributes. As an example, this what I want the test for the ImportModelStateAttribute to do: Setup the filterContext so that TempData[myKey] contains some fake "exported" ModelState (that is, a ModelStateDictionary I create myself, and add one error to) Make ModelState contain one model error. Call OnActionExecuting. Verify the two dictionaries are merged, and ModelState now contains both errors. I'm at a loss already on the second step.

  • What to name an array of flags?

    - by Chris
    I have a project where lots of the objects hold state by maintaining simple boolean flags. There are lots of these, so I maintain them within a uint32_t and use bit masking. There are now so many flags to keep track of, I've created an abstraction for them (just a class wrapping the uint32_t) with set(), clear(), etc. My question: What's a nice accurate, concise name for this class? What name could I give this class so that you'd have a reasonable idea what it was [for] knowing the name only? Some ideas I had: FlagBank FlagArray etc Any ideas? Thanks in advance! Cheers, -Chris

  • Does a WCF service with basicHttpBinding create a new connection for each request?

    - by Phil Wright
    I have a Silverlight client calling a WCF Service on an IIS web server. It uses the default basicHttpBinding setting for the calls. My client code has the usual Visual Studio generated proxy that is generated when using the 'Update Service Reference' menu option. Does every call to the service using that proxy use the same connection? Or does it create a connection each time a call is made and then close it down once the reply is received? As the client is actually making a SOAP call over HTTP I just assumed that every service request had a new connection created but I want to check if that is the case? (I need to know because if it creates a new connection each time then each request could end up at a different server because there are several servers being load balanced. It is uses a single connection for the duration of the proxy then I can assume they all end up at the same machine and so it would cache state.)
