• Can a .csv file be used as a data source in Visual Studio 2008?

  - by Kevin

  I'm pretty new to C# and Visual Studio. I'm writing a small program that will read a .csv file and then write the records read to a SQL Server database table. I can manually parse the .csv file, but I was wondering if it is possible to somehow "describe" the .csv file to Visual Studio so that I can use it as a data source? I should mention that the first two lines in the .csv file contain header information and the following lines are the actual comma-delimited data. Also, I should mention that this program is a stand-alone console program with no user interface.

• Shutting down a WPF application from App.xaml.cs

  - by Johannes Rössel

  I am currently writing a WPF application which does command-line argument handling in App.xaml.cs (which is necessary because the Startup event seems to be the recommended way of getting at those arguments). Based on the arguments I want to exit the program at that point already which, as far as I know, should be done in WPF with Application.Current.Shutdown() or in this case (as I am in the current application object) probably also just this.Shutdown(). The only problem is that this doesn't seem to work right. I've stepped through with the debugger and code after the Shutdown() line still gets executed which leads to errors afterwards in the method, since I expected the application not to live that long. Also the main window (declared in the StartupUri attribute in XAML) still gets loaded. I've checked the documentation of that method and found nothing in the remarks that tell me that I shouldn't use it during Application.Startup or Application at all. So, what is the right way to exit the program at that point, i. e. the Startup event handler in an Application object?

• Can I remove the labels from the bibliography, while keeping them in citations?

  - by Tae

  I'm writing the bibliography of my report with thebibliography environment because I don't need a BibTeX database (or I don't have the time for learn how to customize or write a style). Well, using the optional argument [label] I can specify as I want the cite references are show, for example: \bibitem[PNUD1996]{PNUD1996} PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. So, if I write: in \cite{PNUD1996}. it produces: in [PNUD1996]. But the label also appear in the bibliography: [PNUD1996] PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. Can I to remove the label from the bibliography and keeping it in the reference? I mean, to get: in [PNUD1996]. and PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. Thanks, and sorry for my English :(

• Restrict file access from PHP -> Java Applet

  - by aliuy

  I'm writing a portal in PHP that allows users to upload DICOM images, and allow users of the same group to view those DICOM images through a Java Applet. The html code to display images through the viewer looks like this: <APPLET archive=radscaper.jar codebase=./ code=com.divinev.radscaper.Main.class width=100% height=100%> <PARAM NAME=Config VALUE=config.xml> <PARAM NAME=DicomImg1 VALUE="relative_path1/image1.dcm"> </APPLET> So the generated html passes in a file url to the java applet. The problem I'm facing is - files would be stored in a public directory and easily accessed by anyone knowing the file url. Is there a way I can restrict file access to a certain user group?

• Stored Procedure to create Insert statements in MySql ??

  - by karthik

  I need a storedprocedure to get the records of a Table and return the value as Insert Statements for the selected records. For Instance, The stored procedure should have three Input parameters... 1- Table Name 2- Column Name 3- Column Value If 1- Table Name = "EMP" 2- Column Name = "EMPID" 3- Column Value = "15" Then the output should be, select all the values of EMP where EMPID is 15 Once the values are selected for above condition, the stored procedure must return the script for inserting the selected values. The purpose of this is to take backup of selected values. when the SP returns a value {Insert statements}, c# will just write them to a .sql file. I have no idea about writing this SP, any samples of code is appreicated. Thanks..

• Is there a limit on the number of mutex objects that can be created in a Windows process?

  - by young-phillip

  I'm writing a c# application that can create a series of request messages. Each message could have a response, that needs to be waited on by a consumer. Where the number of outstanding request messages is constrained, I have used the windows EVENT to solve this problem. However, I know there is a limit on how many EVENT objects can be created in a single process, and in this instance, its possible I might exceed that limit. Does anyone know if there is a similar limit on creation of mutex objects or semaphores? I know this can be solved by some sort of pool of shared resources, that are grabbed by consumers when they need to wait, but it would be more convenient if each request message could have its own sync object.

• Hidden features of JSP/Servlet

  - by mkoryak

  I am interested in your tricks etc used when writing JSP/Servlet. I will start: I somewhat recently found out how you can include the output of one JSP tag in an attribute of another tag: <c:forEach items="${items}"> <jsp:attribute name="var"> <mytag:doesSomething/> </jsp:attribute> <jsp:body> <%-- when using jsp:attribute the body must be in this tag --%> </jsp:body> </c:forEach>

• Multiblog engine for asp.net

  - by Andrey

  I know, different forms of this questions were asked on this site multiple times, but I haven't seen a single answer that would satisfy my need. I need a ASP.NET based blogging engine that wouul use SQL Server as a back end and allow multiple independet blogs in one app instance. I'm writing a community website for major bank and blogging is the piece I'm not sure about. Answers to other questions include a broad spectrum from BlogEngine.NET (doesn't support multiple blogs) to CommunityServer (a beast! blogging is just asmall piece of it). I don't want to install a full-blown CRM and just use blogging, I want a blogging engine. I don't mind to buy a commercial one but I can't find one. I'm pretty much stuck, and any ideas are highly appreciated!

• mmap() for large file I/O?

  - by Boatzart

  I'm creating a utility in C++ to be run on Linux which can convert videos to a proprietary format. The video frames are very large (up to 16 megapixels), and we need to be able to seek directly to exact frame numbers, so our file format uses libz to compress each frame individually, and append the compressed data onto a file. Once all frames are finished being written, a journal which includes meta data for each frame (including their file offsets and sizes) is written to the end of the file. I'm currently using ifstream and ofstream to do the file i/o, but I am looking to optimize as much as possible. I've heard that mmap() can increase performance in a lot of cases, and I'm wondering if mine is one of them. Our files will be in the tens to hundreds of gigabytes, and although writing will always be done sequentially, random access reads should be done in constant time. Any thoughts as to whether I should investigate this further, and if so does anyone have any tips for things to look out for? Thanks!

• Obtain Update Table Lock at start of Stored Procedure in SQL Server

  - by Jim Hurne

  I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

• Probability Random Number Generator

  - by Excl

  Let's say I'm writing a simple luck game - each player presses Enter and the game assign him a random number between 1-6. Just like a cube. At the end of the game, the player with the highest number wins. Now, let's say I'm a cheater. I want to write the game so player #1 (which will be me) has a probability of 90% to get six, and 2% to get each of the rest numbers (1, 2, 3, 4, 5). So, how can I generate a number random, and set the probability for each number? Thanks.

• firefox open local link to directory with explorer

  - by raffael

  On a Website for our internal use i show links to local files and folders. the links are like this: href="file://C:/example/" href="file://C:/example/test.odt" The Problem is now that the link to the directory does open in firefox itself with a useless directory listing. Useless because you can just see the files or open them but not copy, insert, delete... The link to the file work normal and the file is opend by OpenOffice. By changing the configuration of firefox and setting the following key to false I can open the directory in with explorer.exe but for the file I have to choose the right application. network.protocol-handler.expose.file Does someone know a way to get both to work like i want? Means that the Directory is shown by explorer.exe and all files are opened by the right application. This can be by configuring Firefox or windows, changing the links, or even by writing a small program which opens all the file protocol correctly and will be used as protocol handler for the file protocol in firefox. Thanks Raffael

• How can I safely raise events in an AsyncCallback?

  - by cyclotis04

  I'm writing a wrapper class around a TcpClient which raises an event when data arrives. I'm using BeginRead and EndRead, but when the parent form handles the event, it's not running on the UI thread. I do I need to use delegates and pass the context into the callback? I thought that callbacks were a way to avoid this... void ReadCallback(IAsyncResult ar) { int length = _tcpClient.GetStream().EndRead(ar); _stringBuilder.Append(ByteArrayToString(_buffer, length)); BeginRead(); OnStringArrival(EventArgs.Empty); }

• Git Specify Remote Source Durring Push

  - by ThinkBohemian

  I have a local git repository a "central" repo at github. I'm working on a part of a project, while a friend is working on a related piece that is its entirely seperate repo, is it possible for me to simply link directly to my friends repo? For example, the app is called widgets. I have all my code in widgets/app/mycode and my friend is writing code that goes into widgets/plugins/awesome/hiscode. I want to be able to always have http://github.com/mycode/widgets/plugins/hiscode to be a direct link or clone to http://github.com/hiscode/awesome ? It could be possible i'm missing something basic in my question or knowledge of git, if so please ask, and i'll be happy to try to fill in the blanks.

• BeautifulSoup, but for CSS?

  - by MTsoul

  BeautifulSoup parses HTML and offers various ways to manipulate and search within HTML. Is there something similar for CSS? Specifically, I'd like to know if a given HTML text is rendered as bold. Either it has an ancestor that is the <strong> or the <bold> tag (which can be done with BeautifulSoup), or it has an ancestor (or itself) that has CSS attributes with font-weight: bold. Is this possible without resulting to writing my own library?

• how to get latex to hyphenate a word that contains a dash ?

  - by Gyom

  In a latex document I'm writing, I get an overfull hbox warning because of the word "multi-disciplinary", which happens to be rendered at the end of a line. I can get rid of this particular warning by changing it into multi-discipli\-nary, but the same problem will happen elsewhere, since this word is used a lot in the paper. I'd like to use the \hyphenation{} command instead, but obviously my tentative \hyphenation{multi-disci-pli-na-ry} does not work, because it does not understand the first dash correctly. What incantation do I need to get correct indentation in a word that already contains a dash ? Bonus question: where could I have found the answer to that question myself ?

• Simulating C-style for loops in python

  - by YGA

  (even the title of this is going to cause flames, I realize) Python made the deliberate design choice to have the for loop use explicit iterables, with the benefit of considerably simplified code in most cases. However, sometimes it is quite a pain to construct an iterable if your test case and update function are complicated, and so I find myself writing the following while loops: val = START_VAL while <awkward/complicated test case>: # do stuff ... val = <awkward/complicated update> The problem with this is that the update is at the bottom of the while block, meaning that if I want to have a continue embedded somewhere in it I have to: use duplicate code for the complicated/awkard update, AND run the risk of forgetting it and having my code infinite loop I could go the route of hand-rolling a complicated iterator: def complicated_iterator(val): while <awkward/complicated test case>: yeild val val = <awkward/complicated update> for val in complicated_iterator(start_val): if <random check>: continue # no issues here # do stuff This strikes me as waaaaay too verbose and complicated. Do folks in stack overflow have a simpler suggestion?

• C++ - dynamic pointer of array

  - by Eagle

  Hi to all, first i would like to say i am Newbie in C++. As part of my master thesis i am writing a program in C++ which also get as parameters the variables m and d (both integers). Were d is the power of 2 (this means 2^d elements). Parameter m define the number of possible interactions between one element and the total group (2^d elements). The number of possible interactions is computed as following: \kappa = \sum_{i=0}^m\binom{d}{i} (at present i generate vector of vectors for 2^d x \kappa, but my Prof. would like me to create different statistics to different m's. My first though was to to generate a dynamic array of m arrays of different sizes... Then i though of defining a 3-dim array with the biggest needed 2d array, but also program speed is important (e.g d = 20). i would like to ask for your advice how to define such kind of dynamic array that will also be fast. Regards

• Push or Pull to Excel for reporting data

  - by Nathan Fisher

  I am unsure which is the best way to go here. I have a third party Excel 2003 spreadsheet that needs to be filled in on a monthly basis and emailed. Currently it is a manual process and I am in the process of automating the generation of the spreadsheet. I have been throwing around different ideas of how to get the data into the spreadsheet. I have thought of using SSRS to create a report that is in a similar format and get the user to cut and past. Alternatively writing a VBA addin that retrieves that data from a webservice and then adds the data to the spreadsheet. Or using the third party spreadsheet as a template and open it on the server via oledb and adding the data then serving it as a downloadable file. Which is better or are the better solutions out there?

• Converting SQL to LINQ to XML

  - by Morano88

  I'm writing the following code to convert SQL to LINQ and then to XML: SqlConnection thisConnection = new SqlConnection(@"Data Source=3BDALLAH-PC;Initial Catalog=XMLC;Integrated Security=True;Pooling=False;"); thisConnection.Open(); XElement eventsGive = new XElement("data", from c in ?????? select new XElement("event", new XAttribute("start", c.start), new XAttribute("end",c.eend), new XAttribute("title",c.title), new XAttribute("Color",c.Color), new XAttribute("link",c.link))); Console.WriteLine(eventsGive); The name of the table is "XMLC" and I want to refer to it. How can I do that? When I put its name directly VS gives an error. Also when I say thisConnection.XMLC it doesn't work.

• PHP4 No Error When Missing Method is Called

  - by INTPnerd

  I have come across an annoying problem while writing some PHP4 code. I renamed the method of a class but I forgot to rename it where it was being called from. The annoying part is it was hard to track down where the problem was because no error was triggered. The script simply aborted leaving the web page partially rendered. Is it normal for this not to trigger an error or is there something wacky going on here? If this is normal is there a way to force this kind of thing to cause an error?

• How to document object-oriented MATLAB code?

  - by jjkparker

  I'm writing a sizable application using object-oriented MATLAB, and this has gotten me thinking about how to document the code. If this was C, I would use Doxygen. For Java, I'd use JavaDoc. Both have mostly agreed-upon standards for how class and method documentation should look and what it should contain. But what about MATLAB code? The most I've seen in TMW's own classes is a short sentence or two at the top of the class, and I can't find any topics devoted to documenting sizable MATLAB applications. So how do you document your MATLAB classes? Any particular style issues or additional tools?

• Haskell Syntax: Parse Error On Input

  - by NuNu

  As part of a mini-haskell compiler that I'm writing, I have a function named app. What I want this function to do is take in these arguments epp (App e1 e2). The first step would be to evaluate e1 recursively (epp e1) and check if the output would be an error. If not then evaluate e2 and then call another function eppVals to evaluate the outputs of the calls on e1 and e2 which I defined as v1 and v2 respectively. epp (App e1 e2) | epp e1 /= Error = eppVals v1 v2 | otherwise = Error where v1 = epp e1 v2 = epp e2 <- parse error on input `=' Logically I believe what I have written so far works but I'm getting a parse error on input = where I stated above. Any idea why? My second try epp :: Exp -> Error Val epp (App e1 e2) = (eppVals v1 v2) where v1 = (epp e1) v2 = (epp e2) But now throws Couldn't match expected type Val with actual type Error Val
