  • Communication between Page and User Controls

    - by Narmatha Balasundaram
    I have a main page that has multiple user controls on it. All the user controls have static text and some data to be retrieved from the DB. The aysnchronous DB call is clubbed at the page level and one call is made to avoid multiple calls (in the different user controls) to get the same data. I want the page and user controls to load initially with the static text and later refresh the contents obtained from the server. To sum it all up, Page Loads = Asyn calls fired on page load = Data received back from the server (XML/text/whatever) = User controls to load with this data using AJAX. What methods do I have to let the user controls know that I have the data from the server and they need to update with this data?

  • Populate an SSRS Report parameter(hidden) by a sproc or user defined function

    - by Nauman
    My SSRS report fetches data from my DATAWAREHOUSE. The ASP.NET application I have is connected to an OLTP database. I invoke the SSRS Report from my ASP.NET application and provide a parameter as CustomerID(this is an application key in datawarehouse) to my report. Since my report is connected to my datawarehouse, I do not query my report databased on the OLTP's CustomerID. Instead I use my datawarehouse's surrogate key (CustomerDimKey). Now, in my report, I need to find the correct surrogate key for the CustomerID parameter, which I passed from my ASP.NET application! My report already has a parameter as @CustomerDimKey(this is used across all the report sprocs). We used it for testing, but now we'll hide this as we have integrated it with the ASP.NET application. I have already added a new parameter to the report as @CustomerID(this will have the OLTP's CustomerID), which will now get a value from ASP.NET. I need to know a way to re-use the @CustomerDimKey report parameter, which should now get value from a sql statement or a sproc once the report is requested. Based on the value contained by the @CustomerID parameter.

  • User Acceptance Testing Defect Classification when developing for an outside client

    - by DannyC
    I am involved in a large development project in which we (a very small start up) are developing for an outside client (a very large company). We recently received their first output from UAT testing of a fairly small iteration, which listed 12 'defects', triaged into three categories : Low, Medium and High. The issue we have is around whether everything in this list should be recorded as a 'defect' - some of the issues they found would be better described as refinements, or even 'nice-to-haves', and some we think are not defects at all. They client's QA lead says that it is standard for them to label every issues they identify as a defect, however, we are a bit uncomfortable about this. Whilst the relationship is good, we don't see a huge problem with this, but we are concerned that, if the relationship suffers in the future, these lists of 'defects' could prove costly for us. We don't want to come across as being difficult, or taking things too personally here, and we are happy to make all of the changes identified, however we are a bit concerned especially as there is a uneven power balance at play in our relationship. Are we being paranoid here? Or could we be setting ourselves up for problems down the line by agreeing to this classification?

  • install software in linux as a non root user

    - by Aki
    Hi, What is the best way to install software in a linux machine if you dont have root permissions. I know that we can use few variables like PKG_CONFIG_PATH and switches like --prefix with configure to get a software installed in a local directory, but sometimes when there are recursive dependencies it is becoming tough for me to install all the packages manually. Is there a better automated way? Update: What i meant by recursive dependencies is: to install package A, i should install package B, which in turn requires package C to be installed

  • Strange EListError occurance (when accessing variable-defined index)

    - by michal
    Hi, I have a TList which stores some objects. Now I have a function which does some operations on that list: function SomeFunct(const AIndex: integer): IInterface begin if (AIndex > -1) and (AIndex < fMgr.Windows.Count ) then begin if (fMgr.Windows[AIndex] <> nil) then begin if not Supports(TForm(fMgr.Windows[AIndex]), IMyFormInterface, result) then result:= nil; end; end else result:= nil; end; now, what is really strange is that accessing fMgr.Windows with any proper index causes EListError... However if i hard-code it (in example, replace AIndex with value 0 or 1) it works fine. I tried debugging it, the function gets called twice, with arguments 0 and 1 (as supposed). while AIndex = 0, evaluating fMgr.Windows[AIndex] results in EListError at $someAddress, while evaluating fMgr.Windws[0] instead - returns proper results ... what is even more strange, even though there is an EListError, the function returns proper data ... and doesn't show anything. Just info on two EListError memory leaks on shutdown (using FastMM) any ideas what could be wrong?! Thanks in advance michal

  • How to check if a variable is defined in a Master file in ASP.NET MVC

    - by Mortanis
    I've got a Site.Master file I've created to be my template for the majority of the site, with a navigation. This navigation is dynamically created, based on a recursive Entity (called Page) - Pages with a parentID of 0 are top level, and naturally each child carries it's parent's Id in that field. I've created a quick little HTML Helper that accepts the ID of an Page and generates the nav by doing a foreach on the children that have a parentId matching the passed Id. On the majority of the site, I want the Site.Master to use a parentId of 0, but if I'm on a strongly typed View displaying a Page, I naturally want to use the Id of the page. Is there a way to do such conditional logic in a Site.Master (and, does that violate MVC rules)? "If I'm on a strongly typed Page of /Page/{Id}, use the Id render nav, else use 0"

  • Special Character Meanings Defined

    - by Noctis Skytower
    In Python's module named string, there is a line that says whitespace = ' \t\n\r\v\f'. ' ' is a space character. '\t' is a tab character. '\n' is a newline character. '\r' is a carriage-return character. '\v' maps to '\x0b' (11). What does it mean and how might it be typed on a keyboard (any OS)? '\f' maps to '\x0c' (12). What does it mean and how might it be typed on a keyboard (any OS)?

  • How to remove the graphical user interface?

    - by Praveen Kumar
    Ok my question is that, I want to run a heavy application, on a Virtual Machine (VirtualBox) with just 2 GB RAM (Windows 7 32Bit Host has 4 GB, 3.5 GB effective). Initially I thought of installing Ubuntu Server 12.04.1, which doesn't come with a GUI, so I thought it would be efficient in performance, but I have only Ubuntu 12.04 Desktop. My question is, is it possible to remove the GUI parts in Ubuntu 12.04 Desktop (Not Server), keeping only the core OS, after installation in a virtual machine? Or, is there anyway to improve the performance of the OS? If you need more information, I am ready to provide. I don't want the GUI or anything, even a small terminal window is fine for me, I can access files through FTP.

  • PHP not obeying my defined ETags

    - by Sam Bisbee
    What I'm doing I'm pulling an image from the database and sending it to the browser with all the proper headers - the image displays fine. I also send an ETag header, using the SHA1 of the image's content as the tag. The images are getting called semi regularly, so caching is a bit of an issue (won't kill the site, but nice to have). The Problem $_SERVER['HTTP_IF_NONE_MATCH'] is not available to me. As far as I can tell, this is because of PHP's "disobey the cache controls" life style. I can't mess with the session cache limiter, because I don't have access. But, even if I did have access, I wouldn't want to touch it: 99% of the site is under WordPress. The Environment PHP 4 (don't ask) Apache 2.2 WordPress The images live in the database (largeblog), which I can't change. Any guidance, tip/tricks, etc. would be helpful. I don't have much room to change the environmental/structural stuff. Cheers.

  • Creating user UI using Flixel

    - by Jamie Read
    I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives. What I am trying to do is add a Start Screen before actually loading the game. I have a create function that adds all the game elements to the stage: override public function create():void // all game elements { How can I add this pre-load Start Screen? I'm not sure if I have to add in the code to this create function or somewhere else and what code to actually add. Eventually I would also like to add saving, loading, options and upgrades too. So any advice with that would be great. Here is my main game.as: package { import org.flixel.*; public class Game extends FlxGame { private const resolution:FlxPoint = new FlxPoint(640, 480); private const zoom:uint = 2; private const fps:uint = 60; public function Game() { super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom); FlxG.flashFramerate = fps; } } } Thanks.

  • Methodology for designing user controls

    - by zSysop
    Hi all, I want to able to create reusable user controls within my web app and i'm wondering on how to go about doing so. Should a user controls properties be visible to a form that's using it? What's the best way to go about loading the controls on the user control from the form thats using it? Should there be a public method within the control that allows you to load it from an external form or should the user control be loaded in the page load event Is it okay to nest user controls within user controls? etc... Thanks for any advice

  • SQL Server and Table-Valued User-Defined Function optimizations

    - by John Leidegren
    If I have an UDF that returns a table, with thousands of rows, but I just want a particular row from that rowset, will SQL Server be able to handle this effciently? SELECT * FROM dbo.MyTableUDF() WHERE ID = 1 To what extent is the query optimizer capable of reasoning about this type of query? How are Table-Valued UDFs different from traidtional views if they take no parameters? Any gotchas I should know about?

  • Netbeans GUI building on pre-defined code

    - by deliriumtremens
    I am supposed edit some code for an assignment, and he gave us the framework and wants us to implement code for it. I load the project into netbeans and can't figure out how I'm supposed to edit the swing components. I don't see how to edit source vs. design. import javax.swing.*; import java.util.*; import java.io.*; public class CurrencyConverterGUI extends javax.swing.JFrame { /************************************************************************************************************** insert your code here - most of this will be generated by NetBeans, however, you must write code for the event listeners and handlers for the two ComboBoxes, the two TextBoxes, and the Button. Please note you must also poulate the ComboBoxes withe currency symbols (which are contained in the KeyList attribute of CurrencyConverter CC) ***************************************************************************************************************/ private CurrencyConverter CC; private javax.swing.JTextField Currency1Field; private javax.swing.JComboBox Currency1List; private javax.swing.JTextField Currency2Field; private javax.swing.JComboBox Currency2List; private javax.swing.JButton jButton1; private javax.swing.JPanel jPanel1; } class CurrencyConverter{ private HashMap HM; // contains the Currency symbols and conversion rates private ArrayList KeyList; // contains the list of currency symbols public CurrencyConverter() { /************************************************** Instantiate HM and KeyList and load data into them.

Therefore, 1 Euro is equivalent to 1.35 USD Use the rate specified for USD to convert to equivalent GBP: amount / USD_rate * GBP_rate ****************************************************************************/ } public ArrayList getKeys(){ // return KeyList } } This is what we were given, but I can't do anything with it inside the GUI editor. (Can't even get to the GUI editor). I have been staring at this for about an hour. Any ideas?

  • Securely automount encrypted drive at user login

    - by Tom Brossman
    An encrypted /home directory gets mounted automatically for me when I log in. I have a second internal hard drive that I've formatted and encrypted with Disk Utility. I want it to be automatically mounted when I login, just like my encrypted /home directory is. How do I do this? There are several very similar questions here, but the answers don't apply to my situation. It might be best to close/merge my question here and edit the second one below, but I think it may have been abandoned (and therefore never to be marked as accepted). This solution isn't a secure method, it circumvents the encryption. This one requires editing fstab, which necessitates entering an additional password at boot. It's not automatic like mounting /home. This question is very similar, but does not apply to an encrypted drive. The solution won't work for my needs. Here is one but it's for NTFS drives, mine is ext4. I can re-format and re-encrypt the second drive if a solution requires this. I've got all the data backed up elsewhere.

  • User directory in PATH in zsh: ~ Does Not Work

    - by Yar
    I'm doing this in my .zshrc PATH="~/scripts:$PATH" and if I do echo $PATH it appears as the first thing in the path. Yet this directory isn't included in the executable path (nor for tab-completion). What am I doing wrong? ls ~/scripts shows the directory as expected. Edit: This works, though... I guess ~ doesn't work in the path? #PATH="~/scripts:$PATH" PATH="/Users/yar/scripts:$PATH"

  • How to manage product backlog/user stories

    - by Andrew Stephens
    We're about to start a new project using Agile (using TFS), and I have a couple of "good practice" questions regarding the product backlog:- When we first start adding users stories, is it a good idea to put them in (say) a "Backlog" iteration, or just leave their iteration blank? Obviously when the time comes to start work on a US it would be moved into the appropriate iteration backlog. When breaking an epic down into smaller USs, would I simply close the original epic, as it's no longer required? Or should I create the new USs as children of the epic? (it's then someone's responsibility to close the epic once all child USs have been completed). Lastly, should the product backlog list all USs regardless of status, or only those that have not been started (i.e in my proposed "Backlog" iteration)? I realise these questions aren't life-or-death, but it would be nice to know how other people manage their product backlogs so we can organise things properly from the start.

  • Database: storing data from user registration form

    - by teggy
    Let's say I have an user registration form. In this form, I have the option for the user to upload a photo. I have an User table and Photo table. My User table has a "PathToPhoto" column. My question is how do I fill in the "PathToPhoto" column if the photo is uploaded and inserted into Photo table before the user is created? Another way to phrase my question is how to get the newly uploaded photo to be associated to the user that may or may not be created next. I'm using python and postgresql.

  • How to draw some lines in a view element defined in the xml layout

    - by Nils
    Hello, I have problems drawing some simple lines in a view object (Android programming). First I created the layout with the view element(kind of painting area) in it (XML file). [...] < View android:id="@+id/viewmap" android:layout_width="572px" android:layout_height="359px" android:layout_x="26px" android:layout_y="27px" [...] ... and tried then to access it to draw some lines. Unfortunately the program is running and other UI elements like buttons are displayed, but I can't see the drawings. What's wrong ? [...] viewmap = (View) findViewById(R.id.viewmap); Canvas canvas = new Canvas(); viewmap.draw(canvas); Paint p = new Paint(); p.setColor(Color.BLUE); p.setStyle(Paint.Style.STROKE); canvas.drawColor(Color.WHITE); p.setColor(Color.BLUE); canvas.drawLine(4, 4, 29, 5, p); p.setColor(Color.RED); viewmap.draw(canvas); [...] Thanks for help :) !

  • Weird problem: IE8 user can't authenticate with web service

    - by NovaJoe
    I have an asp.net app. It has a page that requires authentication. The authenticated user can view the page because he/she is authenticated. The page makes a jQuery Ajax call to a WCF service. The WCF service checks that the user is authenticated via HttpContext. I have a user that is using WinXP and IE8. This user can authenticate to the page, but when the Ajax call is made from the page to the wb service, the user recieves my "session not authenticated" message on the page, generated by the service and displayed on the page. When I use the same OS/browser combo, the page and service work just fine, as expected; no errors. What option in this user's IE settings would cause this behavior?

  • How can I check the mysql connection for a user/password using batch/shell script

    - by machaa
    Hi, How can I check the mysql connection for a user/password using batch/shell script? I've user name and password, and I need to authenticate whether they are correct or not, but how? I tried this way: I've created a batch file "run.bat" with "mysql -u User--password=UserPassword < commands.sql" "commands.sql" file contains "\q" When I run the file "run.bat" the output is nothing when User/Password are correct and "ERROR 1045 (28000): Access denied for user ... " when User/Password are incorrect. Now can we capture this output, and decide whether the connection is successful or not, if yes how? Regards
