• Use ModalPopupExtender without having to set TargetControlID?

  - by Monty

  I'd like to use a modalpopupextender in my asp.net page to show a sub form. But it only has to show on specific conditions. Those conditions are determined in a piece of javascript code. So, most importantly, the modal popup doesn't have to show on a button click. However, if I leave the property TargetControlID empty I get the following exception: The TargetControlID of 'ModalPopupExtender1' is not valid. The value cannot be null or empty. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: The TargetControlID of 'ModalPopupExtender1' is not valid. The value cannot be null or empty. Do I just have the TargetControlID to an hidden button or is there aslo a more decent option? Thanks.

• Android: get all the notifications by code

  - by Profete162

  Hello! I am using some home replacement that allow me to hide the notification Bar and that's something I really like.

As I already developed some applications, I would like to know if there is a command line that allow an application to get all the notifications. I plan to add this to a widget or a toast. Thank a lot for any clue or help.

• Stack overflow in OCaml and F# but not in Haskell

  - by Fernand Pajot

  I've been comparing for fun different languages for speed in execution of the following program: for i from 1 to 1000000 sum the product i*(sqrt i) One of my implementations (not the only one) is constructing a list [1..1000000] and then folding with a specific funtion. The program works fine and fast in Haskell (even when using foldl and not foldl') but stack overflows in OCaml and F#. Here is the Haskell code: test = foldl (\ a b -> a + b * (sqrt b)) 0 create 0 = [] create n = n:(create (n-1)) main = print (test (create 1000000)) And here is the OCaml one: let test = List.fold_left (fun a b -> a +. (float_of_int b) *. (sqrt (float_of_int b))) 0. ;; let rec create = function | 0 -> [] | n -> n::(create (n-1)) ;; print_float (test (create 1000000));; Why does the OCaml/F# implementation stack overflows?

• Why array size in llvm created by llvm's internal tools is not good enough for llvm?

  - by vava

  I'm getting strange error message from the following code: ArrayType * arrayType = ArrayType::get(Type::getInt32Ty(ctx), 0); stack = builder->CreateAlloca(arrayType, ConstantArray::get(arrayType, std::vector<Constant *>())); This code compiles fine but it gives me llvm::Value* getAISize(llvm::LLVMContext&, llvm::Value*): Assertion `Amt-getType() == Type::getInt32Ty(Context) && "Malloc/Allocation array size is not a 32-bit integer!"' failed. during execution. What's interesting, is that I never said of what type array size should be, it was created somewhere inside helper functions. So I naturally see no good reason for assert to be there. But I must be doing something wrong anyway, can you help me spot the problem? Thanks in advance. PS. LLVM, as good as it is, lacking documentation tremendously.

• Sync Framework,LINQ, and my DAL

  - by Refracted Paladin

  I am creating a WPF app that needs to allow users to work in a temporary disconnected state and I plan to use a Local Database Cache. My question's are about my data access layer. Do you typically create the whole DAL to point at the Cache or both and create a switching mechanism? Is Entity's a good way to go for my DAL against the Cache? I am used to L2S but my understanding is that I can't use that against SQLCE, correct? Thanks! PS: Any good resources out there for using Sync, Linq, and WPF ALL TOGETHER? Tutorials, videos, etc?

• Joda-Time: DateTime, DateMidnight and LocalDate usage

  - by fraido

  Joda-Time library includes different datetime classes DateTime - Immutable replacement for JDK Calendar DateMidnight - Immutable class representing a date where the time is forced to midnight LocalDateTime - Immutable class representing a local date and time (no time zone) I'm wondering how are you using these classes in your Layered Applications. I see advantages in having almost all the Interfaces using LocalDateTime (at the Service Layer at least) so that my Application doesn't have to manage Timezones and can safely assume Times always in UTC. My app could then use DateTime to manage Timezones at the very beginning of the Execution's Flow. I'm also wondering in which scenario can DateMidnight be useful.

• MVC2: Best Way to Intercept ViewRequest and Alter ActionResult

  - by Matthew

  I'm building an ASP.NET MVC2 Web Application that requires some sophisticated authentication and business logic that cannot be achieved using the out of the box forms authentication. I'm new to MVC so bear with me... My plan was to mark all restricted View methods with one or more custom attributes (that contain additional data). The controller would then override the OnActionExecuting method to intercept requests, analyze the target view's attributes, and do a variety of different things, including re-routing the user to different places. I have the interception and attribute analysis working, but the redirection is not working as expected. I have tried setting the ActionExecutingContext.Result to null and even have tried spooling up controllers via reflection and invoking their action methods. No dice. I was able to achieve it this way... protected override void OnActionExecuting(ActionExecutingContext filterContext) { filterContext.HttpContext.Response.Redirect("/MyView", false); base.OnActionExecuting(filterContext); } This seems like a hack, and there has to be a better way...

  - by Chad Sellers

  Group, Part 1: I'm currently working on a command line utility that can take args and update a local database.

For example: ~//arrInput.exe "parm1" "pram2" "pram3" Part 2: I would like to take in command line args and use them as input parms for a "stored proc". Once finished execution....used the same inputs crate a log file. For example output file: mm-dd-yyyy hh:mm:ss - pram1,pram2,... pram1: updated/failed pram2: update/failed Thanks, Chad

• Generating a Call Hierarchy for dynamicly invoked method

  - by Maxim Veksler

  Hello, Today's world of dynamic invoke, reflection and runtime injection just doesn't play well with traditional tools such as ctags, doxygen and CDOC. I am searching for a method call hierarchy visualization tool that can display both static and dynamic method invocations. It should be easy to use, light during execution and provide helpful detailed information about the recorded runtime session. Now I guess Callgrind could be considered a valid solution for the family C. What tool / technique could you suggest to create a call graph for both static and dynamic method invocation for JVM based bytecode? The intended end result is a graphical display (preferably interactive) which can show path from main() to each method that was invoked. During research for this post I stumbled upon javashot, it seems that this is the kind of approach I'm aiming at, I would prefer that this would be integrated into a kind of profiler or alike which than can be used from within my IDE (Eclipse, IntelliJ, Netbeans and alike). Thank you, Maxim.

• Zend DB MYSQL Wrapper

  - by Vincent

  All, I have a PHP application written in Zend Framework with MVC style. I plan to use Zend_DB to connect to the MySQL database and process queries. I am looking for a wrapper class which makes it easy to use Zend_DB class. This wrapper class will have a constructor that connects to the Mysql db using Zend_DB. It will also have a method to return a singleton instance for each and every db connection made. Something like: $pptDB = PPTDB::getInstance(); $pptDB->setFetchMode(PPTDB::FETCH_OBJ); $result = $pptDB->fetchRow('SELECT * FROM bugs WHERE bug_id = 2'); echo $result->bug_description; Where class PPTDB extends Zend_DB Is this something feasible to have? If not, how ls would you use Zend_DB in a major application? Thanks,

• Preserving text formatting for dynamic website

  - by Mohit

  Hello Folks, I am facing a problem while creating a dynamic website. I am building it for some pharma company, which have many products. The problem is, every product have different sections of description, and have to be formatted differently. I wanted to store all the product descriptions in the database, but at the same time preserve the formatting of each description. I also plan to provide an admin interface, where they could edit the product information themselves. I could use Joomla or any other CMS for that purpose, but i wanted to know if i want to build such a system of my own, where i could format the text in an editor and them save that thing into database and when i retrieve it, i get the same formatting. How could i do this? Also i wanted to do this in PHP. Thanks -- Mohit

• Recommendations OutSourcing .NET Work To Indian Team [closed]

  - by MT

  hi there, I've been asked to research outsourcing some of our C# winform development work. The aim is to employ a dedicated Indian team of around 5 developers reporting to myself. A google search provides a plethora of different companies, none of which I have ever heard of before. I'm a little skeptical about this plan at the moment but remain open minded. I was hoping some of you guys had some general advice about how to approach this. Or even better recommendations for companies to contact based upon your experiences? Many thanks

• Is url.openStream harmful?

  - by Casebash

  I was using the java.net.URL.openStream() method to retrieve content from the server. I recently ran into an issue where the HTTP Response code indicated an error, but instead of throwing an exception, the stream still was read anyway. This caused the error to appear much later in the execution and proved to be a red herring. As far as I can see, when you have opened a stream using this method, there is no way to check the HTTP response code. The only way I could find to handle this properly was to use code such as: HttpURLConnection conn=(HttpURLConnection) url.openConnection() if(conn.getResponseCode()!=HttpStatus.SC_OK) //Raise Exception; InputStream in=conn.getInputStream() So do you agree? Is it possible to use openStream safely, or is it a method that should be avoided at all costs. It is worth noting that Sun uses the method in their tutorial code for reading directly from a URL. Then again, the code throws Exception so it isn't exactly a bastion of good coding practices.

• Eclipse + Git: Can't add files to my repository

  - by Stegeman

  I use Eclipse (Helios) with PDT and egit. I have a project without versioning, so I created a git repository for it by doing: Team -> Share Project When I try to add the files of my project to the repository: Team -> Add I get an exception: Failed to add resource to index Failed to add resource to index Exception caught during execution of add command When I add the files manually on the command line, everything is working fine.

• Applescript access to last.fm app via application icon in menu bar

  - by Mark

  Hi, I want to create an Applescript to drive the last.fm player app. I'm trying to do this via last.fm application icon in the menu bar rather than using the main application menus, as this approach (I think) won't cause last.fm to switch to the foreground. The overall plan is to bind my script to a quicksilver trigger so I can stop|start|skip|love|ban|tag tracks from the keyboard. My problem is I can't find what UI element to bind the applescript to. I've used UI Browser to scan through the UI object model but it draws a blank with the last.fm icon in the menu bar. Any thoughts appreciated.

• A function's static and dynamic parent

  - by legends2k

  I'm reading Thinking in C++ (vol. 2): Whenever a function is called, information about that function is pushed onto the runtime stack in an activation record instance (ARI), also called a stack frame. A typical stack frame contains (1) the address of the calling function (so execution can return to it), (2) a pointer to the ARI of the function’s static parent (the scope that lexically contains the called function, so variables global to the function can be accessed), and (3) a pointer to the function that called it (its dynamic parent). The path that logically results from repetitively following the dynamic parent links is the dynamic chain, or call chain I'm unable to comprehend what the author means as function's static and dynamic parent. Also am not able to differentiate between item 1, 2 or 3. They all seem to be the same. Can someone please explain this passage to me?

• How to write custom reports in Drupal

  - by Nicholai

  What's the "right" way in Drupal to create reports? I was hoping to use a view but am not having much luck. My goal is to create a table of rows containing three fields: user name, location, SUM of volunteer hours. Once I have this part working, I plan to expose filters for Location and Date. Views Calc only allows you to group by one field. I know Crystal Reports and MSSQL Reporting Services and I was hoping to find a similar kind of thing for Drupal. Is there a framework, examples, or a module to help with this, or do I need to write a custom module implementing the views_alter_SQL hook to get the desired data for each report? EDIT: I ended up getting it to work with BIRT reports, which gave a lot more power than Views could allow. Code is on my blog: http://nicholaiburton.com/blog/2010/creating-custom-reports-for-drupal

• Is there any er diagram tool in Windows that I can use to connect to a MySQL 4.1 database in Unix?

  - by melaos

  I have a few test databases in some Unix SUSE 8 servers and initially the plan was to find some tools which can directly create the ERD straight from the server until someone told me that I can find tools to connect from the Windows PC straight to the Unix MySQL database. So I saw MySQL query analyzer which can do this but unfortunately there are no options to create an ERD. So are there any tools, preferably open source or free which can do this? I've done some basic googling but didn't know what is the exact terms to use to search for this and have so far found nothing useful yet. Updates: I just found out that the latest version of workbench doesn't work MySQL 4.1 Enterprise Edition which is the version that I have! And I try to use fabFORCE DBDesigner but I can't even connect at all using that one :( What can work for this version of MySQL?

• iphone - forcing button to acknowledge touch programmatically

  - by Mike

  When you touch a UIButton it hides for a fraction of second and then it executes its action. This fast "blink" is the feedback the user needs to know that the button has been clicked. In the project I am doing, I need to select the button programmatically, as if the user had clicked it. In other words, the same behavior has the button had been clicked by the user... a fast blink and execution of its action. Is this possible? thanks for any help.

• Is Private Bytes >> Working Set normal?

  - by Jacob

  OK, this may sound weird, but here goes. There are 2 computers, A (Pentium D) and B (Quad Core) with almost the same amount of RAM running Windows XP. If I run the same code on both computers, the allocated private bytes in A never goes down resulting in a crash later on. In B it looks like the private bytes is constantly deallocated and everything looks fine. In both computers, the working set is deallocated and allocated similarly. Could this be an issue with manifests or DLLs (system)? I'm clueless. Also, I compiled the executable on A and ran it on B and it worked. Note: I observed the utilized memory with Process Explorer. Question: During execution (where we have several allocations and deallocations) is it normal for the number of private bytes to be much bigger (1.5 GB vs 70 MB) than the working set?

• Error in retrieving data from Excel File

  I have an excel file. I wanted to pull the data from excel file to SQL Server table. And the data is successfully transferred.In the excel file, I removed a text from one column named "Risk" from one row.The text was lengthy one.now the package execution fails at the source ie from the excel file. The errors are shown as "[Audit [1]] Error: There was an error with output column "Risk" (100) on output "Excel Source Output" (9). The column status returned was: "DBSTATUS_UNAVAILABLE"." and "[Audit [1]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "output column "Risk" (100)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "Risk" (100)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure." the error occurs only when I remove this particular text from this row.

• How can a Delphi TForm / TPersistent object calculate its own deserialization time?

  - by mjustin

  For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.
