• PHP: prevent invocation of method X from from context != Y

  - by sunwukung

  This is a tricky one. I am "emulating" ZF Bootstrapping (surface appearance). Don't ask me why, call it academic interest. So I have a Bootstrap Abstract with a method "run" that iterates over itself to locate any methods prefixed with "init". The application looks for a user defined class which extends this class, in which the user can define any number of methods in this way. However, I want to prevent the user from being able to execute the "run" command of it's parent class, while still exposing the same command for the client code. Anyone got any thoughts/advice/guidance? regards SWK

• WPF: Binding items added to UserControl's exposed children

  - by Brian

  I have a user control that allows items to be added to it by exposing a Grid's Children property. Any control I add shows up fine but when I try to bind a property on the added item to a control in the main window nothing happens (example): <TextBox Name="txtTest" Text="Success!" /> <mycontrols:CustomUserControl.ExposedGridChildren> <TextBox Text="{Binding ElementName=txtTest, Path=Text, FallbackValue=fail}"/> </mycontrols:CustomUserControl.ExposedGridChildren> This example always results in the TextBox's text showing "fail". Here is how I'm exposing the children in the user control: public UIElementCollection ExposedGridChildren { get { return grdContainer.Children; } } Any thoughts? Is it a scope issue? I know I can't name the elements I add to the children because of scope errors. Thanks, Brian.

• Performance statistics hooks

  - by tinny

  Lets be honest, most software that developers produce has quite modest performance requirements. E.g. Systems perhaps serving 100's of requests per second, if that. But lets assume for a moment (or even dream) that you where perhaps involved in the "next big thing" (whatever that means) and you wanted to put some sort of performance statistics logging in place to help you out when all those users come flying in. Performance statistics logging, how would you approach this requirement? Perhaps you would use some sort of generic framework for this? Or roll your own solution? What would you log? How granular? Or would you not even bother putting anything in place and rather deal with this issue when it actually became an issue? It would be really interesting to hear your thoughts on this topic.

• Problem evaluating NULL in an IIF statement (Access)

  - by Mohgeroth

  Item in the recordset rstImportData("Flat Size") is = Null With that, given the following statement: IIF(IsNull(rstImportData("Flat Size")), Null, cstr(rstImportData("Flat Size"))) Result: Throws error 94: Invalid use of Null If I change the statement by removing the type conversion upon a false comparison: IIF(IsNull(rstImportData("Flat Size")), Null, 0) Result: Null It returns Null as it should have the first time. It appears that I cannot do a type conversion in an IIF if the value passed in should ever be null even if it passes an IIF test, it still attempts to evaluate it at both the true and false answer. The only reason I'm using IIF like this is because I have a 25 line comparison to compare data from an Import against a matching record in a database to see if I need to append the prior to history. Any thoughts? The way data is imported there will be null dates and where the spreadsheet import is in a string format I must convert either side to the other to compare the values properly but if either side is null this exception occurs :(

• How to check value of stored procedure output parameter

  - by Anna T

  I have a stored procedure that: A. inserts some rows into a "table variable" based on some joins B. selects all values from column x from that table into a string with comma separated values C. selects all from the "table variable" If I execute the procedure like this: EXEC CatalogGetFilmDetails2 2,111111; a table is returned as instructed per step C above. How can I execute it so that also the output parameter value is displayed? (see point B above). I need to check if it's calculated properly. And since the second parameter is of output type, meaning it's calculated inside the procedure, why is it mandatory to specify a value for it when executing the procedure? I normally use a random value for it, it anyway doesn't matter/impact the result. On the other hand if I try to execute it without the output parameter, it returns an error) Thank you very much! This is how the procedure starts: CREATE PROCEDURE CatalogGetFilmDetails2 (@FilmID int, @CommaSepString VARCHAR(50) OUTPUT) AS And this is how @CommaSepString is calculated: SELECT @CommaSepString = STUFF((SELECT ', ' + Categ FROM @Filme1 FOR XML PATH('')), 1,1,'')

• Arrays in database tables and normalization

  - by Ivan Petrov

  Hi! Is it smart to keep arrays in table columns? More precisely I am thinking of the following schema which to my understanding violates normalization: create table Permissions( GroupID int not null default(-1), CategoryID int not null default(-1), Permissions varchar(max) not null default(''), constraint PK_GroupCategory primary key clustered(GroupID,CategoryID) ); and this: create table Permissions( GroupID int not null default(-1), CategoryID int not null default(-1), PermissionID int not null default(-1), constraint PK_GroupCategory primary key clustered(GroupID,CategoryID) ); UPD: Forgot to mention, in the scope of this concrete question we will consider that the "fetch rows that have permission X" won't be performed, instead all the lookups will be made by GroupID and CategoryID only Thoughts? Thanks in advance!

• Enable Datepicker only when first field has a value

  - by Syed Abdul Rahman

  Right now, the End Date selection is disabled. I want to only enable this when a Start Date is selected. if( $('#datepicker1').val().length === 0) { $('#datepicker2').datepicker("disable"); } else { $('#datepicker2').datepicker("enable"); } This clearly does not work. If I insert value = 'random date' into my first input field, it works fine. I'm not too sure on how do this. Clearly not as easy as I had hoped. My other problem, or hope, is to disable the dates including and before the first selection. You know, pick Start Date, and every date before and said date for the next picker would be disabled. But that is a whole other problem.

• Are there any widely-agreed upon guidelines for rating your language knowledge on a scale?

  - by DVK

  The question was imagined after a co-worker was complaining for an hour about some guy who could not answer basic Java questions on an interview after self-identifying himself as "8 out of 10" on Java. While that was an obvious fib, I personally always had major trouble defining my specific language skills on a sliding scale unless I'm given specific guidelines (remember 40 standard libraries by heart? Able to solve 10 random Project Euler problems in <30 mins each? Can write implementation of A, B and C data-structures from scratch in 30 mins? Know 30% of standard? Can answer 50% of questions on StackOverflow pertaining to the language?) So, I was wondering - is there some sort of commonly accepted methodology for translating such tangible benchmarks into "rate yourself on a language between 1-10"? "Kernighan gets an A, God gets a B, everyone else gets C and less" type jokes are not helpful :)

• NSString simple pattern matching

  - by SirRatty

  Hi all, Mac OS 10.6, Cocoa project, 10.4 compatibility required. (Please note: my knowledge of regex is quite slight) I need to parse NSStrings, for matching cases where the string contains an embedded tag, where the tag format is: [xxxx] Where xxxx are random characters. e.g. "The quick brown [foxy] fox likes sox". In the above case, I need to grab the string "foxy". (Or nil if no tag is found.) Each string will only have one tag, and the tag can appear anywhere within the string, or may not appear at all. Could someone please help with a way to do that, preferably without having to include another library such as RegexKit. Thank you for any help.

• JavaScript socket vs. Flash socket?

  - by Dr.Dredel

  Steve Jobs just posted this article on why Apple rejects Flash... http://www.apple.com/hotnews/thoughts-on-flash/ I agree that javascript and css can be used to replicate some of Flash's animation, though Flash does all sorts of scaling and tweening that is incredibly powerful, and I'm not sure that there's anything comparable in javascript, if there is, I certainly haven't seen it. However, my question is about the socket. Flash has an incredibly powerful openSocket class that allows you to connect to a server and have the server and the client talk back and forth to one another. As far as I know there is no equivalent class in Javascript. Am I mistaken? Is there some secret mystery Ajax class that replicates the openSocket? If not, then that feature alone makes Flash an invaluable tool. I'm interested in all answers though... and yes this IS a programming question! :)

• Regex in Flex 3: How to Wrap Quotations Around a Dynamic String?

  - by Laxmidi

  Hi, I need some Regex help. I need to find beacon_ followed by an alphanumeric code and then wrap it in quotation marks. For something static, like the example, below it's straight forward. myReturn = myReturn.replace( 'id=beacon_80291ee9b3', 'id="beacon_80291ee9b3"'); But, my problem is that the part after beacon is a random alphanumeric code. (However, it is always the same length). For example, the beacon part could be: beacon_c8ac873136 beacon_dc83b5953e beacon_7a910d03d8 etc. The haystack that I'll search will look like: myReturn = "blah blah id=beacon_80291ee9b3 blah blah"; Thanks. -Laxmidi

• Reading a client's header from Python CGI script?

  - by jawonlee

  I'm writing a very simple web service, written in Python and run as CGI on an Apache server. According to Python docs (somewhere... I forgot where), I can use sys.stdin to read the data POSTed by a random client, and this has been working fine. However, I would like to be able to read the HTTP header information as well - incoming IP, user agent, and so on. I'd also like to keep it very simple for now, by using only Python libraries (so no mod-python). How do I do this?

• flex chat/telnet application send/receive same window in TextArea

  - by Renassaince Geek

  Hi there, Just wanting to know if anybody has seen an example of a telnet/chat or other console like FLEX application where you can use the same TextArea as input/ouput area. I've been trying to modify the app at: http://livedocs.adobe.com/flex/3/html/17_Networking_and_communications_8.html but so far, computer says no. All the implementations I've seen use a combination of TextInput and TextArea. The challenge is that we'll be using this app to telnet into some old routers and we'll need to do a fair amount of copy/pasting. Based on what I've seen, it seems that I would need to point the mouse into the TextInput in order to be able to right click and paste, which is not very sleak..... Your thoughts, Fran

• Are concurrency issues possible when using the WCF Service Behavoir attribute set to ConcurrencyMode

  - by Brandon Linton

  We have a WCF service that makes a good deal of transactional NHibernate calls. Occasionally we were seeing SQL timeouts, even though the calls were updating different rows and the tables were set to row level locking. After digging into the logs, it looks like different threads were entering the same point in the code (our transaction using block), and an update was hanging on commit. It didn't make sense, though, because we believed that the following service class attribute was forcing a unique execution thread per service call: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerCall)] We recently changed the concurrency mode to ConcurrencyMode.Single and haven't yet run into any issues, but the bug was very difficult to reproduce (if anyone has any thoughts on flushing a bug like that out, let me know!). Anyway, that all brings me to my question: shouldn't an InstanceContextMode of PerCall enforce thread-safety within the service, even if the ConcurrencyMode is set to multiple? How would it be possible for two calls to be serviced by the same service instance? Thanks!

• IIS url rewrite rewriting all .asp to .html

  - by user335711

  I need to create rules for web.config that will rewrite all requests for files with extension .html to .asp and redirect all .asp requests to .html Example: file_xyz.asp rewrites to file_xyz.html directory1/file_xyz.asp rewrites to directory1/file_xyz.html and file_xyz.html redirects to file_xyz.asp directory1/file_xyz.html redirects to directory1/file_xyz.asp What is the syntax for the rule Is this too broad a rule? If I should need for what ever reason to have a physical file such as file_abc.html how do I exclude it from the redirect rule? I am thinking I should just use ISAPI_Rewrite http://www.isapirewrite.com/ there seems to be a ton of resources out there for rewriting with htaccess and very little online help for using IIS 7 URL rewrite. Any thoughts and/or advice Thanks in advance

• Why is the proper "respond_to" format not getting called?

  - by humble_coder

  Hi All, I'm having a bit of an odd issue. Really too odd to type out, but here goes. Basically I have a controller that refuses to "respond_to" using javascript unless I assign my "chart.generate_xml" to a variable before the "respond_to" block like so: @xml = @chart.generate_xml(@begin_date,@end_date,1.hour) respond_to do |format| format.html format.js{ render :update do |page| page.insert_html :bottom, "chart-div", @xml #page.insert_html :bottom, "chart-div", @chart.generate_xml(@begin_date,@end_date,1.hour) end } If I remove the upper "@xml= …" portion and go with the lower "page.insert", the "format.js" section doesn't get called. And if I try to force the format with "request.format = :js", I get the javascript returned as text. I'm not doing anything special here in that method call, so I'm not sure why it would choose to respond any differently. FWIW, the method that triggers this controller action is using JS to do so, so I'm confused as to why "format.js" isn't always getting called. Thoughts? Best.

• Why does the VBA Editor open on its own sometimes?

  - by Kevin Finn

  I've created a small script in Outlook 2003 VBA that watches for new appointments, and sets them to tentative and no reminder as I create them. However, I now find that seemingly at random, the VBA editor will open itself. It doesn't happen when I actually use the new script, but it did happen this morning when I un-hibernated my laptop, for example. The editor doesn't pop up any runtime errors or highlight any lines in the script, it's just there as if I had pressed Alt-F11 to launch it. Sometimes I close other apps and see that it's been sitting back there for a while. This behavior has only been occurring since I created this new script. Any ideas why this would occur? Thanks!

• Workaround for PHP SOAP request failure when wsdl defines service port binding as https and port 80?

  - by scooterhanson

  I am consuming a SOAP web service using php5's soap extension. The service' wsdl was generated using Axis java2wsdl, and whatever options are used during generation result in the port binding url being listed as https://xxx.xxx.xxx.xxx**:80** If I download the wsdl to my server, remove the port 80 specification from the port binding location value, and reference the local file in my soapclient call it works fine. However, if I try to reference it remotely (or download it and reference it locally, as-is) the call fails with a soap fault. I have no input into the service side so I can't make them change their wsdl-generation process. So, unless there's a way to make the soapclient ignorant of the port, I'm stuck with using a locally modified copy of someone else' wsdl (which I'd rather not do). Any thoughts on how to make my soapclient ignore the port 80?

• svn hangs when connecting to server but only for me!

  - by vgm64

  I've checked out two repositories with svn and they both have some odd behavior when using commands like svn -u status. That command in particular will hang, and top says the process is sleeping. I can check out and update those repos (usually), but this in particular will hang until I kill -9 it. It doesn't happen on anyone else's computer (I'm running Mac OSX 10.6) who uses these repos. I just checked out a fresh clean version of one of the repos, and did svn -u status and it froze. Anyone have any thoughts? Could some settings be corrupted?

• summer experiment: GWT & python for a trading game- arch question

  - by sadhu_

  Hi, As a summer learning experiment, I'm thinking of coding up a web front end for a trading game i wrote in python, that generates share prices and random snippets of text. I am sort of struggling with how this should work on the back-end though. I'd rather have my GWT client page interact with the python share price generator, than to try and re-code it in java. I suppose i could use an sqlite db, and then use jdbc to pick up the prices, but i was wondering if there is a better way, for me to be able to poll some python script either from my client page, or from the serverside java code ? I found this python wrapper, but i'm not sure how i could use it though: http://code.google.com/apis/visualization/documentation/dev/gviz_api_lib.html Thanks.

• My site was recently attacked. What do I do?

  - by ChrisH

  This is a first for me. One of the sites I run was recently attacked. Not at all an intelligent attack - pure brute force - hit every page and every non-page with every extension possible. Posted with garbage data to every form and tried to post to some random urls too. All tod, 16000 requests in one hour. What should I do to prevent/alert this kind of behavior? Is there a way to limit the request/hr for a given ip/client? Is there a place I should be reporting the user to? They appear to be from China and did leave what seems like a valid e-mail.

• When and why are you planning to upgrade to Python 3.0?

  - by Tomislav Mutak

  Python 3.0 (aka Python 3000, Py3k, etc) is now available. When and why are you planning on porting your project or code to the new Python? edit: I'm particularly interested in any features that don't exist in 2.6 that make porting worth it. Right now seems like a lot of negatives (x hasn't been ported yet), but I don't know what people see as the positives. Regarding "when", I'm interested in people's thoughts that the first step to porting is to have "excellent test coverage" which seems a bit optimistic for some projects.

• How to use SMS content provider? Where are the docs?

  - by Mark

  Hi, I'd like to be able to read the system's SMS content provider. Basically I wanted to make an SMS messaging app, but it would only be useful if I could see past threads etc. It seems like there's a content provider for this, but I can't find documentation for it - anyone know where that is? Thanks -------- edit ----------- Ok I found a way to get the sms inbox provider, and I just dumped all the column names in that provider, looks like this: Uri uriSms = Uri.parse("content://sms/inbox"); Cursor c = context.getContentResolver().query(uriSms, null,null,null,null); // column names for above provider: 0: _id 1: thread_id 2: address 3: person 4: date 5: protocol 6: read 7: status 8: type 9: reply_path_present 10: subject 11: body 12: service_center 13: locked I'm just piecing this together from random threads I find around the net, I'm really wondering where this is all documented (if at all)? Thanks again

• Complex select query question for hardcore SQL designers

  - by eugeneK

  Very complex query been trying to construct it for few days with more real success. I'm using SQL-SERVER 2005 Standard What i need is : 5 CampaignVariants from Campaigns whereas 2 are with the largest PPU number set and 3 are random. Next condition is that CampaignDailyBudget and CampaignTotalBudget are below what is set in Campaign ( calculation is number of clicks in Visitors table connected to Campaigns via CampaignVariants on which users click) Next condition CampaignLanguage, CampaignCategory, CampaignRegion and CampaignCountry must be the ones i send to this select with (languageID,categoryID,regionID and countryID). Next condition is that IP address i send to this select statement won't be in IPs list for current Campaign ( i delete inactive for 24 hours IPs ). In other words it gets 5 CampaignVariants for user that enters the site, when i take from user PublisherRegionUID,IP,Language,Country and Region view diagram
