• File I/O OS handling

  - by Albinoswordfish

  This isn't a direct coding question but more of a OS handling mechanism. I was reading somebody's previous question regarding C# and file handling. Apparently C# was throwing an exception regarding a file being locked when trying to access this. So my question is, does C# use an internal lock to handle file I/O between processes, or does the OS use some type of mutual exclusion for file I/O? From what I learned about operating systems, well at least unix, is that the OS doesn't implement any type of mutual exclusion for processes trying to access the same file.

• Handling multiple sessions for same user credentials and avoiding new browser window opening in my w

  - by Kabeer

  Hello. I want to handle following scenarios in my new web application. If multiple users log into the application with same credentials, the application should deny access. Since I have out of process session store, I would be able to make out when this situation happens. So I can deny all requests after first successful attempt. This will however not work if the user instead of logging out of the application, closes the browser. The session will continue to reflect in the store for the period of timeout value. If a user attempts to open a new browser windows (Ctrl+N), the application should defeat this attempt. Every new page can potentially fiddle with cookies. I want to therefore deny the users the ability to open new window.

• ASP.NET - dynamically creating database connection in datasets

  - by Foo

  I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects. Any ideas?

• How can I play compressed sound files in C# in a portable way?

  - by skolima

  Is there a portable, not patent-restricted way to play compressed sound files in C# / .Net? I want to play short "jingle" sounds on various events occuring in the program. System.Media.SoundPlayer can handle only WAV, but those are typically to big to embed in a downloadable apllication. MP3 is protected with patents, so even if there was a fully managed decoder/player it wouldn't be free to redistribute. The best format available would seem to be OGG Vorbis, but I had no luck getting any C# Vorbis libraries to work (I managed to extract a raw PCM with csvorbis but I don't know how to play it afterwards). I neither want to distribute any binaries with my application nor depend on P/Invoke, as the project should run at least on Windows and Linux. I'm fine with bundling .Net assemblies as long as they are license-compatible with GPL. [this question is a follow up to a mailing list discussion on mono-dev mailing list a year ago]

• How can I find which process has opened a specific file?

  - by Hosam Aly

  How can I find which processes have a specific file opened, and their open, access and share modes? Additionally, is it possible to change these values for a process? Or is it even possible to open a file for reading if it is already opened for exclusive access by another process? Please note that I don't want to invalidate the handle of the process having the file opened. I just want to be able to access the file (if possible). (I'm mainly asking about Windows, but solutions for other platforms are welcome, since they contribute to the community's knowledge.) Edit: I found some answers for my first question here and there. Edit 2: Thanks everybody for the tools you mentioned, but I am mainly looking for programmatical techniques (e.g. using Win32 APIs).

• Creating a multiplayer card game

  - by Vikram.exe

  Hi, I was trying to make a multiplayer card game. I know networking concepts, so I know how to handle data between successive turns. I Haven't done a similar thing before so if any one could point me to a tutorial, that would be nice. I am comfortable with html/php/javascript and a bit of adobe flash. Please suggest are these sufficient to create a game or should I go for some other language(s)? Which are the best languages that are currently used to create such multiplayer games? Thanks, Vikram

• How to create a custom admin configuration panel in Django?

  - by Matteo

  Hi, I would like to create a configuration panel for the homepage of the web-app I'm designing with Django. This configuration panel should let me choose some basic options like highlighting some news, setting a showcase banner, and so on. Basically I don't need an app with different rows, but just a panel page with some configuration options. The automatically generated administration area created by Django doesn't seem to handle this feature as far as I can see, so I'm asking you for some directions. Any hint is highly appreciated. Thank you in advance. Matteo

• .Net System.Net.HttpWebRequest & Authentication Cookies

  - by James

  I would like to know if the following is possible: As part of the PageLoad of an ASP.Net page request: Use HttpWebRequest (POST) to make a request to a forms authentication webpage of a different web application Examine the response to see if the authentication succeeded (identifiable if an authentication cookie has been set) If it fails, then finish the ASP.Net page request, which will display a message saying "couldn't auto-login" or some such thing If success, then instead of completing the ASP.Net page lifecycle, use "Response.Write" to send the response from the HttpWebRequest back to the browser (thus essentially displaying the webpage from the HttpWebRequest) If the above is possible, then, is there also a way to transfer the authentication cookie from the HttpWebResponse to the requesting browser? My gut feeling is probably not - but if this is the case, then how do proxy servers handle such things? Is that not essentially what they are doing? Thanks for any help

• jeditable in an ASP.NET web form

  - by Barney

  Can someone explain to me how you would use jeditable with an ASP.NET web form (and C# codebehind). I've got a bit of experience with web forms but not very complicated stuff, and haven't used much jquery before, and this is just puzzling me. I understand how to put it in and attach it to the element you want to be editable, it's what jeditable does when you submit the text field that I don't get. How do you handle that in the webform in order to save the changed text? Hope someone understands my issue... Cheers!

• Regex and PHP for extracting contents between tags with several line breaks

  - by John

  How can I extract the content between tags with several line breaks? I'm a newbie to regex, who would like to know how to handle unknown numbers of line break to match my query. Task: Extract content between <div class="test"> and the first closing </div> tag. Original source: <div class="test">optional text<br/> content<br/> <br/> content<br/> ... content<br/><a href="/url/">Hyperlink</a></div></div></div> I've worked out the below regex, /<div class=\"test\">(.*?)<br\/>(.*?)<\/div>/ Just wonder how to match several line breaks using regex. There is DOM for us but I am not familiar with that.

• What's the easiest way to parse numbers in clojure?

  - by Rob Lachlan

  I've been using java to parse numbers, e.g. (. Integer parseInt numberString) Is there a more clojuriffic way that would handle both integers and floats, and return clojure numbers? I'm not especially worried about performance here, I just want to process a bunch of white space delimited numbers in a file and do something with them, in the most straightforward way possible. So a file might have lines like: 5 10 0.0002 4 12 0.003 And I'd like to be able to transform the lines into vectors of numbers.

• Regular expression to replace quotation marks in HTML tags only

  - by Cindyydnic

  I have the following string: <div id="mydiv">This is a "div" with quotation marks</div> I want to use regular expressions to return the following: <div id='mydiv'>This is a "div" with quotation marks</div> Notice how the id attribute in the div is now surrounded by apostrophes? How can I do this with a regular expression? Edit: I'm not looking for a magic bullet to handle every edge case in every situation. We should all be weary of using regex to parse HTML but, in this particular case and for my particular need, regex IS the solution...I just need a bit of help getting the right expression.

• Tomcat 5.5, Is there a max upload speed per request?

  - by maclema

  I am having an issue when uploading files to tomcat. It seems that tomcat (or something else?) will not handle the upload as fast as I can send it. When uploading multiple files concurrently I can max out my local connection upload speed (2.1MB/s). However, when uploading only one file at a time, no matter how small or large the file, the upload will max out around 400KB/s. I have tried setting the appReadBufSize higher but it makes no difference. Is there something else that would be limiting the upload speed per request? Proxy Server: CentOS 4 Apache 2 SSL Tomcat Server: CentOS 4 Tomcat 5.5.25 (Tomcat Native Library Is Installed) Java 6 Thanks! Matt

• How do I set the color for the editButtonItem in the navigation bar of a UITableViewController ?

  - by eemceebee

  Hi I have a UITableViewController where I added a "editButtonItem" in the navigation bar : self.navigationItem.leftBarButtonItem = self.editButtonItem; No magic here, but I try to define the color (background and foreground/textcolor) of this button. I read in the Apple forum somewhere that the button changes the color if I change the navigationbar to the same color, well despite the fact that I do not get this to work either (for testing) I do not want to touch the navigationbr itself, just the button. Since this button is already predefined I am not sure how to handle this. Do I need to overwrite the button with my own definition or can I just simply apply a new style (if so how ?) Thx

• Calling SSIS from BizTalk Orchestration

  - by aceinthehole

  I have a scenario were I need to move a vast amount of data, and I need to use BizTalk to control the flow and contain the business logic. The problem is that BizTalk will not be able to handle the amount of data that needs to be moved. We have decided to a BizTalk Orchestration to kick off an SSIS package that does the actual heavy lifting. However, there is a caveat in that we have to be able to pass information into SSIS such as file location and info about how to split certain data up. My question is, what is the best way to call into SSIS from an Orchestration given those parameters? Should I build a webservice around it? Is there an adapter or stored procedure that I can call? Or is there a way to call it directly from the Orchestration?

• NSTask or NSThread?

  - by Ben Packard

  I have some code that is attached to an NSTimer. Around 5 times every second, it interacts with another application (by emulating keystrokes) and when appropriate spits out an NSNotification, that is handled by another piece of code. While the timer code is running, the UI is unresponsive, so I can't include a 'stop' button that halts the timer. How should I handle this? A separate process (NSTask right?) or thread? Remember that at unpredictable times, the timer code will need to send some info back for processing. Thanks.

• Parsing complex string using regex

  - by wojtek_z

  My regex skills are not very good and recently a new data element has thrown my parser into a loop Take the following string "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write" Previously I had the following for my regex : [+\\-/] Which would turn the result into USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read But now I have values with dashes in them which is causing bad output New string looks like "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write/FUNCTION=Read-Write" Which gives me the following result , and breaks the key = value structure. USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read Write Can someone help me formulate a valid regex for handling this or point me to some key / value examples. Basically I need to be able to handle + - / signs in order to get combinations.

• Loop through all subclasses in an Android view?

  - by Slapout

  I’m working on a game for Android. To help implement it, my idea is to create a subclass of a view. I would then insert several instances of this class as children of the main view. Each instance would handle detecting when it was pressed (via OnTouchListener). The problem I’m having now is how do I loop through all these sub-views so I can read their statuses and process them? (I.e. when they all reach a certain state something should happen). Or is there a better way to have several objects on the screen that respond to touch and whose status I can check?

• Scrolling textboxes programmatically using WndProc messages.

  - by Hannes Nel

  Hi, I'm trying to scroll a textbox using the form's WndProc method. The code I've come up with so far, after scouring the internet, looks like this: private void ScrollTextBox() { scrollMessage = Message.Create(TabContents.Handle, 0x00B6, new IntPtr(0x0003), new IntPtr(0x0000)); this.WndProc(ref scrollMessage); } where TabContents is a TextBox. For some reason, nothing happens when i call this method. I'd like to know why. I realise that i can accomplish the same with the MoveToCaret method, but I'm curious why this is not working.

• Avoid painting over nested controls

  - by Cobus Kruger

  I am writing a toolbar-style control and use the ThemeServices unit to paint the background required by the toolbar. Like so: ThemeServices.DrawElement(Canvas.Handle, ThemeServices.GetElementDetails(trRebarRoot), ARect); I then drop child controls onto the toolbar and voila - instant toolbar. Except that every now and again I notice that the nested (child) controls don't repaint as well. So my control paints its background and the child controls disappear until you move the mouse over them. Some of the edit controls show their client area (no border) and some of them are just gone altogether. This happens mostly when I place a window from another application over the toolbar and move it away. I keep thinking this has to be very easy to cure, that perhaps I'm somehow preventing the paint message from reaching the child controls, or missing an override but I have been unable to figure it out.

• Rebuilding lazily-built attribute when an underlying attribute changes in Moose

  - by friedo

  I've got a Moose class with a lazy_build attribute. The value of that attribute is a function of another (non-lazy) attribute. Suppose somebody instantiates the class with a value of 42 for the required attribute. Then they request the lazy attribute, which is calculated as a function of 42. Then, they have the nerve to change the first attribute! The lazy one has already been built, so the builder will not get called again, and the lazy attribute is now out-of-date. I have a solution now where I maintain a "dirty" flag on the required attribute, and an accessor on the lazy one checks the dirty flag and rebuilds it if needed. However, this seems like a lot of work. Is there a way to handle this within Moose, e.g. using traits?
