• Customer provider Password Reset client.

  - by ProfK

  I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.

• global applied stylesheet link on debian box

  - by James

  Hi there, Having some trouble identifying what is wrong with my link to an external CSS stylesheet... I am using a debian box to host some things... including a file i am accessing page.py which is located in /var/www/cgi-bin. I need this page to link to a css file which currently has the pathname /var/www/styles.css. Now I know I could link as: <link rel="stylesheet" href="**../styles.css**" type="text/css"> and the problem is solved but I would rather have a 'global' link, that I can use in other py files elsewhere in my filesystem and they will all point to /var/www/styles.css The information I have searched suggests that <link rel="stylesheet" href="**/var/www/styles.css**" type="text/css"> should work fine... but it doesn't. I have tried multiple combinations of everything I know but it doesn't seem to link as I would expect. Can anyone point me in the right direction?

• How to name variables which are structs

  - by evilpie

  Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non capitalized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

• GWT: Loading different UI's based on URL

  - by jmccartie

  Trying to get a GWT project off the ground and finding it difficult to do any basic routing. Trying to fire up different UI's based on the URL. Thought I could set a string based on the getHash() and then switch off that, but seems cumbersome (and annoying since I can't do string-based switches in Java). There's got to be a best practice for this. I know Gerrit uses hashes for determining this type of information but couldn't find where they do it in the source. Or is this totally not GWT-related? Something I can handle in web.xml? Any help is much appreciated.

• Beginner: Best Practices in an Android App UI Navagation

  - by AndyD273

  I am trying to learn how to do stuff in Android, and I'm not sure of the best way to build the interface. I've been working on porting an iPhone app, which uses navigation controllers and table views for looking at the different sections: basically, someone touches a cell in the table, which drills down to another table. when they touch a cell on that table it drills down to a webview that displays the information. I want to do something similar for the android app, but I don't know how, or if there is a better way native to Android. I've figured out how to use the webview to my purposes, but moving forward and backward in the table tree is unclear.

• Are there any medium-sized web applications built with CGI::Application that are open-sourced?

  - by mithaldu

  I learn best by taking apart something that already does something and figuring out why decisions were made in which manner. Recently I've started working with Perl's CGI::Application framework, but found i don't really get along well with the documentation (too little information on how to best structure an application with it). There are some examples of small applications on the cgi-app website, but they're mostly structured such that they demonstrate a small feature, but contain mostly of code that one would never actually use in production. Other examples are massively huge and would require way too much time to dig through. And most of them are just stuff that runs on cgiapp, but isn't open source. As such I am looking for something that has most base functionality like user logins, db access, some processing, etc.; is actually used for something but not so big that it would take hours to even set them up. Does something like that exist or am i out of luck?

• Rails3 Redirect for javascript/ajax

  - by Tiago

  Hi, I'm using a form with the remote => true. I have a validation that is working correctly. My problem is when the user enters all the correct information and writes the data at this time I do a redirect to the page of the show. Instead of redirecting, it displays the html of the show in my div. How can I make a javascript redirect that will understand? I did not want to use the window.location. Thanks...

• Accessing individual HABTM records in a form

  - by Pichan

  I'm building a form in my CakePHP project that lets you edit a company's information. Among all other things, every company has at least one geographical area in which the company operates, but it may have more. The areas are selected individually using select dropdowns. The relationship between companies and areas is HABTM, because I need to be able to change the amount of associated areas without modifying the database. Currently the associations and corresponding data are handled separately, which isn't really a problem but I was wondering how it could be done using as much Cake's own 'automagic' functionality as possible?

• DOS Batch file - Copy file based on filename elements

  - by user1848356

  I need to sort alot of files based on their filename. I would like to use a batch file to do it. I do know what I want but I am not sure of the correct syntax. Example of filenames I work with: (They are all in the same directory originally) 2012_W34_Sales_Store001.pdf 2012_W34_Sales_Store002.pdf 2012_W34_Sales_Store003.pdf 2012_November_Sales_Store001.pdf 2012_November_Sales_Store002.pdf 2012_November_Sales_Store003.pdf I would like to extract the information that are located between the "_" signs and put them into a different variable each time. The lenght of the informations contained between the _ signs will be different everytime. Example: var1="2012" var2="W34" (or November) var3="Sales" var4="001" If I am able to do this, I could then copy the files to the appropriate directory using move %var1%_%var2%_%var3%_%var4%.pdf z:\%var3%\%var4%\%var1%\%var2% It would need to loop because I have Store001 to Store050. Also, there are not only Sales report, many others are available. I hope I am clear. Please help me realize this batchfile!

• DRY vs Security and Maintainability with MVC and View Models

  - by Mystere Man

  I like to strive for DRY, and obviously it's not always possible. However, I have to scratch my head over a concept that seems pretty common in MVC, that of the "View Model". The View Model is designed to only pass the minimum amount of information to the view, for both security, maintainability, and testing concerns. I get that. It makes sense. However, from a DRY perspective, a View Model is simply duplicating data you already have. The View Model may be temporary, and used only as a DTO, but you're basically maintaing two different versions of the same model which seems to violate the DRY principal. Do View Models violate DRY? Are they a necessary evil? Do they do more good than bad?

• Selecting data from mysql table and related data from another to join them

  - by knittledan

  Ive looked at other questions and answers but still dont understand which brings me here. I have one data base two tables. lets say table1 and table2 from database. I'm looking to grab all the information from table1 and only one column from table2 that coincides with the correct row in table1. Example which I know is wrong: SELECT table1.*, table2.time_stamp FROM table1, table2 WHERE table1.ticket_id=$var AND table1.user_id = table2.user_id Basically select data from table1 then use a value from the selected table to grab the related data from table2 and join them to output them as one mysql_query. Im sure its simple and has been asked before. edit: I dont receive an error. SQL just returns noting. log form of this would be: $sqlResults = mysql_query("SELECT table1.* FROM table1 WHERE table1.ticket_id=$var") while($rowResult = mysql_fetch_array( $sqlResults )) { $userID = $rowResult['user_id']; $sqlResults2 = mysql_query("SELECT table2.time_stamp FROM table2 WHERE table2.user_id=$userID") } I want to combine that into one sql statement so i dont have to hit table2 for every row table1 has

• MVC partial page update

  - by GB

  Hello, I have an MVC project where I have a form with fields a user can enter and save. On that same page I have a table which shows a brief listing of information that the user just saved. The problem I am having is trying to update only the table after a save and not an entire page refresh. Is this possible in jquery or MVC? If so does anyone have an example. Here is what the action in the controller looks like: public ActionResult RefreshList() { string _employeeID = Request.QueryString["empIDSearch"]; this.ViewData["coursehistorylist"] = _service.ListCoursesByEmpID(_employeeID); return View("CourseHistoryList"); } The function in the view: (and this is where I'm confused on how to update only the table) $.ajax({ url: "/Home/RefreshList", type: "POST", success: function(result) { alert("got here"); }, error: function(xhr, ajaxOptions, thrownError) { alert(xhr.status + " " + thrownError + " " + ajaxOptions); } }); Thanks.

• iPhone/iPad fatal error in C++ code produces no output in the log

  - by morgancodes

  I'm trying to move away from Objective-C to C++ for audio in my iPad programming, due to the a few reports I've heard of Objective-C selectors sometimes causing audio glitches. So I'm starting to use pure C++ files. When a fatal error happens in one of the C++ files, I get no output from the log. The app just crashes. For example, if I do this in my C++ file: env = new ADSR(); cout << "setting env to null\n"; env = NULL; env->setSustainLevel(1); cout << "called function on non-initialized env\n"; I get the following output: setting env to null After that, there's a method called on NULL, which apparently kills the app, but absolutely nothing to that effect is reported. What do I need to do to have useful information logged when there's an error in my C++ code?

• Find all those columns which have only null values, in a MySQL table

  - by Robin v. G.

  The situation is as follows: I have a substantial number of tables, with each a substantial number of columns. I need to deal with this old and to-be-deprecated database for a new system, and I'm looking for a way to eliminate all columns that have - apparently - never been in use. I wanna do this by filtering out all columns that have a value on any given row, leaving me with a set of columns where the value is NULL in all rows. Of course I could manually sort every column descending, but that'd take too long as I'm dealing with loads of tables and columns. I estimate it to be 400 tables with up to 50 (!) columns per table. Is there any way I can get this information from the information_schema? EDIT: Here's an example: column_a column_b column_c column_d NULL NULL NULL 1 NULL 1 NULL 1 NULL 1 NULL NULL NULL NULL NULL NULL The output should be 'column_a' and 'column_c', for being the only columns without any filled in values.

• cron stops running when processing multiple items

  - by James

  Cron stops running (no visible error) after a few hours when I add more than 5 jobs in my cron tab. Each job runs every minute (polls a webpage for information which takes 1 second). I tried putting all of my php jobs in a shell script and called this shell script instead but the same problem occurs. Cron stops running, no error in the log file, no error email sent out either. Anyone encountered this before? Where/how canI debug this?

• android spectrum analysis of streaming input

  - by TheBeeKeeper

  for a school project I am trying to make an android application that, once started, will perform a spectrum analysis of live audio received from the microphone or a bluetooth headset. I know I should be using FFT, and have been looking at moonblink's open source audio analyzer ( http://code.google.com/p/moonblink/wiki/Audalyzer ) but am not familiar with android development, and his code is turning out to be too difficult for me to work with. So I suppose my questions are, are there any easier java based, or open source android apps that do spectrum analysis I can reference? Or is there any helpful information that can be given, such as; steps that need be taken to get the microphone input, put it into an fft algorithm, then display a graph of frequency and pitch over time from its output? Any help would be appreciated, thanks.

• Insert a default row into a combobox that is bound to a datatable?

  - by John M

  On a winform there is a combobox that derives its information from a datatable. The datatable draws from a database list. this.cboList.DataSource = pullData(); this.cboList.DisplayMember = "fieldA"; Once the DataSource is set I am not able to insert a default row (ie *) as the first item in the combobox. I tried this: this.cboList.Items.Insert(0,"*"); Is there a way to insert in the combobox after the datasource is set or should this be done in the datatable?

• Can I write to different jetty databases using JPA that is using the same "entity class"

  - by Per

  I am using Java persistance and there EntityManager class and have it assigned to storage a class object that shall be written to the database. My problem is that I want to write to different databases using the same storage class. My solution to that was to write a StorageManagerfactory that has a Map holding all EntityManagers. The solution looked good until I looked at the databases and realized that all information (undepending of the Map, which gets the correct value) was written to the same database (one of the initialised in the Map). So my question is: Can I write to different databases using JPA that is using the same storage class (the class holding the structure of my database)? Thanks

• Jquery Help : Draggable to Sortable and then back to draggable again.

  - by Swamy g

  I have a pool of items in the drag list which is connected to a sortable using connectToSortable option. Now I want to remove some items from this sort list and move them back to the drag list. Sort of like an undo. Suppose the user moves some 5 items to sort list and decides he/she wants only 4 items, and decides to just drag the unwanted item from the sortlist TO the drag list. How do I accomplish this WITHOUT adding a "remove" link in the sort list. Thanks a lot.

What I am asking is, what is the best way to store and then display this type of data. I want to DISPLAY data from my database to show like it would in the image. Should I have a column in my database for each column on the table, then say either A,B,C or D depending on what column it is in but then how would I display it using PHP in my code provided? Im struggling to find a good way of explaining this, I am sorry.

• How to write multiple files from one NSData object?

  - by Kevin Cupp

  Hi there! I'm writing an iPhone app that includes in-app purchasing. It downloads a zip file, then I unzip the file using the popular NSData category (zlibDeflate) which outputs the uncompressed file into an NSData object. The zip file contains multiple files in it which I need to write to the Documents directory. How can I write each file separately from this one NSData object? writeToFile just writes the whole thing to one file. Thank you and let me know if you need any more information.

• Server.Transfer - What could be the issue here?

  - by Younes

  We have implemented a website with the ability for the user to post his actioncode. This then will be checked by the code and when the user has a price the website will Server.Transfer him to another page. The strange thing here is that the user information will be submitted to the database and the actioncode can't be used again. Here we go... I have one user in this database that is inserted twice very fast after the first time he was added. This are the timestamps: 2010-04-23 07:54:41.133 2010-04-23 07:54:41.417 The insert statement is only called once from the code and the user gets Server.Transfered to the Price.aspx page where he sees what price he won. How can it be that this happened? I'm guessing the user hitted F5 but then he had to be very very fast... Thx!
