ASP.NET: How to assign ID to a field in DetailsView?

- by jawonlee

I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time. I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do? Thank you in advance.

Regular Expression to get the size value of a CSS property?

- by thiesdiggity

I wrote a regular expression to get the size from a CSS property: /(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i but for some reason its not working as intended. For example, when I run the following: preg_match_all('/(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i', "border-bottom:1px solid #99999;", $matches); It outputs: 1px 99999; But I only want the 1px value returned. I understand why its returning the above but can't seem to figure out how to only return the size and not the color value. I tried using the following negative lookbehind but it's not working either: /(((?<!#\d{3}|#\d{6})[+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i I want to use preg_match_all for those CSS properties that can have multiple size values (i.e. margin). Anyone have any ideas how to get this regex to return only the size values? Thanks for your help!

Remove only first instance of a character from a list of characters

- by Luke

Hi All, Here's what I want to do. I have 2 strings and I want to determine if one string is a permutation of another. I was thinking to simply remove the characters from string A from string B to determine if any characters are left. If no, then it passes. However, I need to make sure that only 1 instance of each letter is removed (not all occurrences) unless there are multiple letters in the word. An example: String A: cant String B: connect Result: -o-nec- Experimenting with NSString and NSScanner has yielded no results so far.

Scrollview always scrolls to the bottom

- by neha

Hi all, I have a view with scrollview as the detailedview of the table cells which is having contents as multiple labels with dynamic size and a couple of buttons which I'm creating through interface builder. Whenever I tap a cell this view is shown to me but the view is always the bottom view. If I scroll up, I'm able to see the content above but when I leave, it again resets its position i.e. the bottom of the view. Can anybody please help? Thanx in advance.

Test/expand my email regex

- by Ross

I'm really not confident with Regex, I know some basic syntax but not enough to keep me happy. I'm trying to build a regular expression to check if an email is valid. So far here's what I've got: [A-Za-z0-9._-]+@[A-Za-z0-9]+.[A-Za-z.]+ It needs to take account of periods in the username/domain and I think it works with multiple TLDs (e.g. co.uk). I'm working with the preg engine in PHP so it needs to work with that. Thanks if you can help!

exporting html table multi line columns to excel multi line cells

- by Passat

I have a html table in a view MVC4 that I am sending to excel as output. Inside the view page I have some columns that have multiple lines that are built with forloops within the HTML. What's the best way to add the or \r\n so that excel renders it correctly? I have a table and inside I build each row looping thru a recordset. In each row I also loop thru different recordsets to populate columns within each row so that some of the columns may contain more than one value and they should show in different lines in the table that will export to excel.

Async stream writing in a thread

- by blez

I have a thread in which I write to 2 streams. The problem is that the thread is blocked until the first one finishes writing (until all data is transferred on the other side of the pipe), and I don't want that. Is there a way to make it asynchronous? chunkOutput is a Dictionary filled with data from multiple threads, so the faster checking for existing keys is, the faster the pipe will write. void ConsumerMethod(object totalChunks) { while(true) { if (chunkOutput.ContainsKey(curChunk)) { if (outputStream != null && chunkOutput[curChunk].Length > 0) { outputStream.Write(chunkOutput[curChunk]); // <-- here it stops } ChunkDownloader.AppendData("outfile.dat", chunkOutput[curChunk], chunkOutput[curChunk].Length); curChunk++; if (curChunk >= (int) totalChunks) return; } Thread.Sleep(10); } }

Is there any way to prevent the display of unmatched xml tags using xslt?

- by StevenWilkins

Here is a contrived example of an xml document. In my real world case, the xml is fairly complex with multiple nested levels. <alphabet> <a>A</a> <b>B</b> <c>C</c> ... and so on </alphabet> Using xslt, I want to transform the document so that only the vowels are printed. In my real world case, we're using empty template match tags to block the display. But that's too verbose for my liking.

What frameworks exist for data subscription and update?

- by Timothy Pratley

There is one server with multiple clients. The clients are viewing subsets of the servers entire data. If the data that a client is viewing changes, the client should be informed of the changes so that it displays the current data. Example: Two clients are viewing a list of users in an administration screen. One client adds a new user to the list and modifies the permissions of another user. The other client sees the changes propagated to their view. In the client side code I would like the users list to be updated by the framework itself, raising changed events such that it will be redrawn - similar to 'cells' or dataflow. I am looking specifically for a .NET or java implementation.

TextBox loses text when InvokeRequired == false

- by Tom

This is modified code I found on this site. When appending text to a TextBox and InvoveRequired is false the text will display in the box but the next time the function is called and InvokeRequired is true the text string placed by the first call is lost (""). Multiple calls when InvokeRequired is true work as expected. comBox is a type TextBox with multline = true. Any help would be appreciated. public void LogComText(string comText, bool newline) { if (comBox.InvokeRequired) { comBox.BeginInvoke(new Action(delegate { LogComText(comText, newline); })); return; } comBox.AppendText(comText); if (newline) comBox.AppendText(Environment.NewLine); }

Do you leave Windows Automatic Updates enabled on your production IIS server?

- by Nobody

If you were running a 24/7 website on Windows Server 2003 (IIS6). Would you leave the Windows automatic update feature enabled or would you turn it off? When enabled, you always get the latest security patches and bug fixes automatically as soon as they're available, which is the most secure choice. However, the machine will sometimes get automatically rebooted to apply the updates leading to a couple of minutes of downtime in the middle of the night. Also, I've seen rare occasions where the machine does not restart correctly resulting in further downtime. If auto updates are off, when do you apply the patches? I guess you have to use a load balancer with multiple web servers and rotate them out of the production site, apply patches manually, and put them back in. This can be logistically inconvenient when the load balancer is managed by a hosting company. You will also have machines in production that don't always have the latest security patches and you have to routinely spend time deciding which patches to apply and when.

Removing groups of similar records in MySQL query

- by user1182155

I'm trying to wrap my head around this... (it may be simple, been a long day!) I have a database with sometimes multiple similar records... ie. Apples 2008-09-03 Apples 2012-01-01 Apples 2013-10-24 Oranges 2012-01-04 What I need to do is do a query that will show only records that haven't been updated today... So in this case, since Apples has an entry that was updated today, none of the records for the Apples should appear in the results. Oranges should be the only record it returns. I have a query similar to this... SELECT fruit FROM fruitnames where date < CURDATE() Which works to remove the record that was updated today... But it keeps the other records for Apples (obviously)... How would I remove those results as well?

How to modify the Title Bar text for SQL Server Management Studio?

- by DaveDev

Sometimes I keep multiple instances of SQL Server Management Studio 2005 open. I might have the dev database open in one, and the production database open in another. These appear in the Windows task bar with the text "Microsoft SQL Serve...", which means it's impossible to differentiate between them unless I open the window and scroll the Object Explorer up to see what server the window is actually connected to. Is ther any way that I can get the window to display the server name first, and then the name of the application? Like "Dev-DB.database_name - Microsoft SQL Serve..." or whatever?

Using nsIZipWriter or other to compress a string as a string?

- by Daniel

I need to be able to take a javascript string, compress it using any fast and available means and get back a binary string/blob. Background: The extension I'm developing needs to send various large content to my server. It does this conveniently by dynamically creating a form, adding fields to the form and posting it. Some of these fields are just too big bandwidth wise for multiple use. I'd like to be able to compress them before adding them and then maybe base64'ing them if the characters cause a problem in the message. Any ideas? I could use nsiZipWriter with temporary files on disk but that is quite ugly and probably sluggish.

Does MySQL allow two primary keys on one table?

- by Bharanikumar

CREATE TABLE Orders -> ( -> ID SMALLINT UNSIGNED NOT NULL, -> ModelID SMALLINT UNSIGNED NOT NULL, -> Descrip VARCHAR(40), -> PRIMARY KEY (ID, ModelID) -> ); Basically, this appears to me to be creating two primary key on one table. Is that correct? I thought that we could create a number of unique keys in one table, but only one primary key. How is it that my system is allowing the creation of multiple primary keys? Please advise: what are the rules governing this?

How can I take eclipse out of MDI mode?

- by user51189

Does anyone know of a way to make Eclipse an SDI application rather than an MDI one? SDI - Single document interface, each pane is its own window MDI - Multiple document interface, all of the panes are stuck inside one "master" window. Eclipse is an MDI application. All of the little panes (like the call stack, variable viewer, ect) are part of the one master Eclipse window. Rather than having all of the windows stuck inside one master "eclipse" window, I'd like them to all be their own free-floating windows.

How do I create a list of timedeltas in python?

- by eunhealee

I've been searching through this website and have seen multiple references to time deltas, but haven't quite found what I'm looking for. Basically, I have a list of messages that are received by a comms server and I want to calcuate the latency time between each message out and in. It looks like this: 161336.934072 - TMsg out: [O] enter order. RefID [123] OrdID [4568] 161336.934159 - TMsg in: [A] accepted. ordID [456] RefNumber [123] Mixed in with these messages are other messages as well, however, I only want to capture the difference between the Out messages and in messages with the same RefID. So far, to sort out from the main log which messages are Tmessages I've been doing this, but it's really inefficient. I don't need to be making new files everytime.: big_file = open('C:/Users/kdalton/Documents/Minicomm.txt', 'r') small_file1 = open('small_file1.txt', 'w') for line in big_file: if 'T' in line: small_file1.write(line) big_file.close() small_file1.close() How do I calculate the time deltas between the two messages and sort out these messages from the main log?

Problem with accessing in DOM with jQuery

- by Tristan

Hello, I changed the tree of my JSON-P output, and i cannot access to my object DOM anymore : Here's my output : jsonp1271634374310( {"Inter-Medias": {"name":"Inter-Medias","idGSP":"14","average":"80","services":"8.86"} }); And here's my jQuery script : success: function(data, textStatus, XMLHttpRequest){ widget = data.name; widget += data.average ; .... I know one level is missing, but if I try to do : data.Inter-Medias.name or data.name.name it's still not working. Any idea please ? I will have case where i'll have multiple Ojbect, so i want to display all of them, how to do that ? for (i=0;i < data.length;i++) Does it look right ? Bonus question : i understand function(data, textStatus, XMLHttpRequest) that in case of success this function is triggered, the data is what the script recieved from his request, but i have no idea what textStatus or XMLHttpRequest are here too and why ?! Thank you.

javascript not working on localhost

- by Adam McMahon

Ok so I'm lost here, frustrated and pulling my hair and out. Plus probably about to be fired or take a pay cut. I moved Files from a development server to my local machine. The files are consistent (used diff tool), all the dependencies are there. It works for the most part. The problem is that the some of the javascript (not all) is just not working. We're using jquery and a lot of plugins for it. I've checked with the web developer plugin in firefox and all the js files are loading. I cleared the cache in both firefox and chrome multiple times to no avail. The development server is a windows server running wamp. My local machine is running ubuntu. Somebody tell me what I missed.

Reusing a vector in C++

- by Bobby

I have a vector declared as a global variable that I need to be able to reuse. For example, I am reading multiple files of data, parsing the data to create objects that are then stored in a vector. vector<Object> objVector(100); void main() { while(THERE_ARE_MORE_FILES_TO_READ) { // Pseudocode ReadFile(); ParseFileIntoVector(); ProcessObjectsInVector(); /* Here I want to 'reset' the vector to 100 empty objects again */ } } Can I reset the vector to be "vector objVector(100)" since it was initially allocated on the stack? If I do "objVector.clear()", it removes all 100 objects and I would have a vector with a size of 0. I need it to be a size of 100 at the start of every loop.

But on our prod we have multiple apache servers having aliases to a code base on a different server. Here in this case i am not sure where to keep .htacess file on. Should i be keeping it on code base or on the individual apache servers. How can i write the same stuff that i have written in .htaccess file to httpd.conf file.

How should flushing be handled in a doctrine EntityManager instance shared across different services in symfony2?

- by Jbm

I have defined several services in symfony 2 which persist changes to the database. These services have the doctrine instance as one of their dependencies: a.given.service: class: Acme\TestBundle\Service\AGivenService arguments: [@doctrine] If I have two different services and both of them persist objects through the EntityManager, which is obtained like this from the doctrine instance: $em = $doctrine->getEntityManager(); Would all services always share the same EntityManager? If so, how should I handle flushing if I wanted to handle all the changes in a single transaction? I have checked this: http://docs.doctrine-project.org/projects/doctrine-orm/en/2.0.x/reference/transactions-and-concurrency.html and it explains how to handle different transactions in a request, but I want to achieve the opposite, which is having different changes in different services handled as a single transaction. Is there a better approach to handle multiple changes in different services? For now my best bet is having a front-end service in charge of calling the other services and doing the flushing afterwards. Backend services would persist objects but would not do any flushing.
