  • From .NET TO SQL

    - by Berlioz
    How do you pass a value from your DAL to your sproc so that the ISNULL function will do it's job. Particularly the DATE value coming from my .NET assembly. In T-SQL an INSERT STMNT and in the VALUES clause, the line of interest goes like this; ISNULL(@myparm_forcolumn9, @myparm_forcolumn9). What value do I pass from .NET to make this line in my sproc work universally, so I don't have to write a millions INSERT SPROCS for every combination of columns??? I just want to write one stored procedure(sproc) that will handle all INSERTS in my universe.

  • How can I locally debug file permission issues in Visual Studio?

    - by robertc
    I want to debug an ASP.Net website as it attempts to write a file to a directory. When actually deployed this file would possibly not be writeable by the worker process so an error would be thrown, this is not a problem as I just want to catch the error, inform the user and move on. Of course, if I'm debugging on my local machine then I'm an administrator and I have permission to write to the file, so I can't check that I've trapped the correct errors and I can't step through an see where it goes wrong if I haven't. Is there a standard approach to this sort of thing?

  • Resizing iframe height using javascript issue

    - by Camran
    I have an iframe which content is a php-file, and that php-file displays some mysql records. The more records, the larger the iframe height should get, otherwise it wont show all of the information in the iframe. Here is a code I have for dynamically setting the iframe height, from the iframes content (the php file): var x = document.body.scrollHeight; x = x + 20 + 'px'; window.parent.document.getElementById("iframe001").style.height=x; iframe001 is the iframe I am referring to above. I am adding 20px of height extra because of borders etc... Now, sometimes this resizing works, sometimes it doesn't. Does anybody know why it works sometimes. If I alert the 'x' variable, it shows different values sometimes, but most times it works. Any other ways you know of setting the iframes height from the content of the iframe? Thanks

  • How do I create a class in Javascript?

    This is what I got so far, and it's not working at all :( <!DOCTYPE html> <html lang="en"> <head> <title>Class Test</title> <meta charset="utf-8" /> <style> body { text-align: center; background-color: #ffffff;} #box { position: absolute; left: 610px; top: 80px; height: 50px; width: 50px; background-color: #ff0000; color: #000000;} </style> <script type="text/javascript"> document.onkeydown=function(event){keyDown(event)}; document.onkeyup=function(event){keyUp(event)}; var box = 0; function Player () { var speed = 5; var x = 50; var y = 50; } function update() { box.style.left = this.x + "px"; box.style.top = this.y + "px"; box.innerHTML = "<h6 style=\"margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px;\">X: "+ this.x + "<br /> Y: " + this.y + "</h6>"; } var player = new Player(); var keys = new Array(256); var i = 0; for (i = 0;i <= 256; i++){ keys[i] = false; } function keyDown(event){ keys[event.keyCode] = true; } function keyUp(event){ keys[event.keyCode] = false; } function update(){ if(keys[37]) player.x -= player.speed; if(keys[39]) player.x += player.speed; player.update(); } setInterval(update, 1000/60); </script> </head> <body> <div id="box" ></div> <script type="text/javascript"> box = document.getElementById('box'); box.innerHTML = "<h6 style=\"margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px;\">X: "+ player.x + "<br /> Y: " + player.y + "</h6>"; </script> </body> </html>

  • [SQL] Getting the sum of several columns from two tables

    - by romaintaz
    I want to get the sum of several columns from 2 different tables (these tables share the same structure). If I only consider one table, I would write this kind of query: SELECT MONTH_REF, SUM(amount1), SUM(amount2) FROM T_FOO WHERE seller = XXX GROUP BY MONTH_REF; However, I would like to also work with the data from the table T_BAR, and then have a select query that return the following columns: MONTH_REF SUM(T_FOO.amount1) + SUM(T_BAR.amount1) SUM(T_FOO.amount2) + SUM(T_BAR.amount2) everything grouped by the value of MONTH_REF. Note that a record for a given MONTH_REF can be found in one table but not in the other table. In this case, I would like to get the sum of T_FOO.amount1 + 0 (or 0 + T_BAR.amount1). How can I write my SQL query to get this information? For information, my database is Oracle 10g.

  • how do you get the response back into the instance of the object?

    - by randomdev
    If you've written a class in JavaScript that calls a remote service's API, and that remote API offers a callback, how do you get the response back into the instance of the object that made the request? I'll try to give you a very basic example FOO for making cross domain calls to BAR service which offers a callback. Please ignore the usual security concerns, (I own both servers). function FOO() { this.response = null; this.execute = function(url) { var script = document.createElement('script'); script.src = url; document.getElementsByTagName('head')[0].appendChild(script); } this.catch = function(response) { this.response = response; } } var sample = new FOO(); sample.execute('http://barservices.com/sample/?callback={ plshelphere: this.catch}'); I have a way to make this work, but I'm curious if there is an "accepted approach" here. Anyone have thoughts for me?

  • Lucene search on specific field name?

    - by Rachel
    I have been playing around with an installation of SOLR that indexes some data from my database. I am able to index data and query it back but I was wondering about how field name queries work. For certain fields I am able to specify their name and the search text to have the results return as expected and for other fields, when I specify their name and search text, no results are returned. q=type:book //(this will work) q=type:book AND title:"The Title" //(no results returned) In this example, type is a required field and title is not. For the example where I search by title, I can see the document in the results of the first query having the given title so I know that a document exists that matches this search. Is making a field 'required' the only way to be able to search by field name? [edit] I'm using the default installation and the 'example' folder inside of solr, editing the xml files and using the interface available through start.jar to be able to run, index and query.

  • getElementsByTagName() equivalent for textNodes

    - by levik
    Is there any way to get the collection of all textNode objects within a document? getElementsByTagName() works great for Elements, but textNodes are not Elements. Update: I realize this can be accomplished by walking the DOM - as many below suggest. I know how to write a DOM-walker function that looks at every node in the document. I was hoping there was some browser-native way to do it. After all it's a little strange that I can get all the <input>s with a single built-in call, but not all textNodes.

  • Regular expression Not working properly n case of multiple trailing ]]]]

    - by ronan
    I have the requirement that in a textbox a user can jump to the next word enclosed in [] on a tab out for example Hi [this] is [an] example. Testing [this] So when my cursor is at Hi and I do a tab out , the characters enclosed in the [this] are highlighted and when I again do a tabl out th next characters enclosed in following [an] are highlighted. This works fine Now the requirement is whatever the text including the special chars between [] needs to be highlighted case 1: when I have trailing ]]], it only highlights leading [[[ and ignores ]]]] e.g case 2: In case of multiple trailing ] e.e [this]]]] is [test], ideally one a single tabl out from this , it should go to next text enclosed in [] but a user has to tab out 4 times one tab per training ] to go to next [text] strong text The code is $(document).ready(function() { $('textarea').highlightTextarea({ color : '#0475D1', words : [ "/(\[.*?\])/g" ], textColor : '#000000' }); $('textarea').live('keydown', function(e) { var keyCode = e.keyCode || e.which; if (keyCode == 9) { var currentIndex = getCaret($(this).get(0)) selectText($(this), currentIndex); return false; } }); }); function selectText(element, currentIndex) { var rSearchTerm = new RegExp(/(\[.*?\])/); var ind = element.val().substr(currentIndex).search(rSearchTerm) currentIndex = (ind == -1 ? 0 : currentIndex); ind = (ind == -1 ? element.val().search(rSearchTerm) : ind); currentIndex = (ind == -1 ? 0 : currentIndex); var lasInd = (element.val().substr(currentIndex).search(rSearchTerm) == -1 ? 0 : element.val().substr(currentIndex).indexOf(']')); var input = element.get(0); if (input.setSelectionRange) { input.focus(); input.setSelectionRange(ind + currentIndex, lasInd + 1 + currentIndex); } else if (input.createTextRange) { var range = input.createTextRange(); range.collapse(true); range.moveEnd('character', lasInd + 1 + currentIndex); range.moveStart('character', ind + currentIndex); range.select(); } } function getCaret(el) { if (el.selectionEnd) { return el.selectionEnd; } else if (document.selection) { el.focus(); var r = document.selection.createRange(); if (r == null) { return 0; } var re = el.createTextRange(), rc = re.duplicate(); re.moveToBookmark(r.getBookmark()); rc.setEndPoint('EndToStart', re); return rc.text.length; } return 0; } Please let me know to handle two above cases

  • Can jQuery perform a compound select against the top level only?

    - by harpo
    Basically, is there a way to write a.children('.outer').children('.inner') without the intermediate selector? I can't write $('.outer > .inner', a) because I don't want to do full-depth search against a — I know that the .outer elements are immediate children of a. It's partly a matter of "elegance", but partly because I'm trying to avoid "throwaway" element sets. Yes, jQuery may in effect do the same thing, but it has a better chance of optimizing (at least in theory), when it knows the full query's intent.

  • Most proper way to use inherited classes with shared scopes in Mongo?

    - by Trip
    I have the TestVisual class that is inherited by the Game class : class TestVisual < Game include MongoMapper::Document end class Game include MongoMapper::Document belongs_to :maestra key :incorrect, Integer key :correct, Integer key :time_to_complete, Integer key :maestra_id, ObjectId timestamps! end As you can see it belongs to Maestra. So I can do Maestra.first.games But I can not to Maestra.first.test_visuals Since I'm working specifically with TestVisuals, that is ideally what I would like to pull. Is this possible with Mongo. If it isn't or if it isn't necessary, is there any other better way to reach the TestVisual object from Maestra and still have it inherit Game ?

  • How to save a complete webpage using the built-in webbrowser in c#

    - by Mike
    Overall I am trying to write out a webpage to PDF. There is a web service that I can use to convert a file to pdf. So what I am trying to do is save out a webpage from the WebBrowser winforms control. I have already tried writing it out the document stream but that just gives me the html of the page and not the images that are used with it. Another way that I looked into, but have not been successful with, is trying to create an image of the WebBrowser document. I found some examples on the web that utilize the DrawToBitmap function but none of them have worked for me. Any assistance would be grateful.

  • newline in Rackspace Cron Job email

    - by senloe
    I'm running backups against multiple databases hosted at Rackspace. This is working fine. The problem I'm running into is with the results email. I'm using Response.Write to write a message to the web page which is used for logging and is also consumed by the results mail sent out by the job. The problem is I can't seem to get newlines to appear between log messages. The logfile stored on the server is correct, but only the first newline shows up in the email. The mail is in Plain Text format so I tried using "\n" and System.Environment.Newline and neither work. I also tried using <br/> with no luck. Does anybody have any ideas?

  • Javascript : random number between variables issue

    - by Mayhem
    I've seen the other examples on this site but I just can't get it to work. I'm trying to generate a random number between 2 user input variables on a form. The numbers will always be positive numbers. min = document.getElementById('min').value; max = document.getElementById('max').value; waitTimer = Math.floor(Math.random() * (max - min + 1)) + min; When min = 5 / max = 10, waitTimer is sometimes returning results like 2, 4 and 28 and so on. What am I doing wrong?

  • How do I access a DIV from javascript, if ASP.NET mangles its ID?

    - by Rising Star
    I have a web page that contains a "div" element. On the page, there is javascript to reference the div: document.getElementById('divId'). This was working fine until another developer redesigned the page to use an ASP master page. Now, document.getElementById('divId') returns null. It appears that ASP.net prepends some characters to the names of elements within contents forms when you use a master page. How can I know what the id of the div is when the page loads? Update Allow me to give a specific example to clarify the question: My page had a div with ID divNotice. After changing my page to use a master page, I see when I print the source to the page that renders that the div ID is ctl00_ContentPlaceHolder1_divNotice. My question is, how am I supposed to know what the div ID is going to be when the framework is done with it?

  • Which event to catch for application shut down?

    - by xueru
    I am using jQueryMobile and phoneGap for a cross-device mobile application. I use html 5 local storage to persist records that worked on by user. I don't know which phoneGap event to catch just before application shut-down so I can make sure data is saved before shutdown completes. Base on suggestion from naughtur, I tried both unload and beforeunload events, neither of them got fired during app shutdown. Following is my code snip: function persistTasks(){ alert ("is unloading the app"); offlineTasklist.set("tasks", tasklist); } function init() { document.addEventListener("unload", persistTasks, false); login(); } $(document).ready(init);

  • How to test if an array contains a pair of numbers whose product is odd?

    - by John
    How can I write a function that takes an array of integers and returns true if their exists a pair of numbers whose product is odd? What are the properties of odd integers? And of course, how do you write this function in Java? Also, maybe a short explanation of how you went about formulating an algorithm for the actual implementation. Yes, this is a function out of a textbook. No, this is not homework—I'm just trying to learn, so please no "do your own homework comments."

  • Powershell - remote folder availability while counting files

    - by ziklop
    I´m trying to make a Powershell script that reports if there´s a file older than x minutes on remote folder. I make this: $strfolder = 'folder1 ..................' $pocet = (Get-ChildItem \\server1\edi1\folder1\*.* ) | where-object {($_.LastWriteTime -lt (Get-Date).AddDays(-0).AddHours(-0).AddMinutes(-20))} | Measure-Object if($pocet.count -eq 0){Write-Host $strfolder "OK" -foreground Green} else {Write-Host $strfolder "ERROR" -foreground Red} But there´s one huge problem. The folder is often unavailable for me bacause of the high load and I found out when there is no connection it doesn´t report an error but continues with zero in $pocet.count. It means it reports everything is ok when the folder is unavailable. I was thinking about using if(Test-Path..) but what about it became unavailable just after passing Test-Path? Does anyone has a solution please? Thank you in advance

  • PHP export to text file - Only saving first line.

    - by wertz8090
    I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

  • Regex for zeroing in on build output text error

    - by Mike Atlas
    I'd like to quickly hone in on what failed in a build log output that is nearly 5k lines long, using Notepad++ as my editor for the file. Notepad++ has the nice ability to specify regular expressions, so I am wondering if there is a way to not match: Compile complete -- 0 errors, 0 warnings but to match, for example: Compile complete -- 1 errors, 0 warnings Compile complete -- 100 errors, 0 warnings where the match would be (1 or more) errors. If this isn't possible, I will probably just write a quick line-by-line parsing tool instead, but I was hoping someone on StackOverflow could whip out a regular expression in the same amount of time - I'm definitely not proficient enough with regular expressions to be able to write one for my needs in a short amount of time.
