• What SQL is being sent from a SqlCommand object

  - by Justin808

  I have a SqlCommand object on my c# based asp.net page. The SQL and the passed parameters are working the majority of the time. I have one case that is not working, I get the following error: String or binary data would be truncated. The statement has been terminated. I understand the error and but all the columns in the database should be long enough to hold everything being sent. My questions, Is there a way to see what the actual SQL being sent to the database is from SqlCommand object? I would like to be able to email the SQL when an error occurs. Thanks, Justin

• dojo connect mouseover and mouseout

  - by peirix

  When setting up dojo connections to onmouseover and onmouseout, and then adding content on mouseover, dojo fires the onmouseout event at once, since there is new content. Example: dojo.query(".star").parent().connect("onmouseover", function() { dojo.query("span", this).addContent("<img src='star-hover.jpg'>"); }).connect("onmouseout", function() { dojo.destroy(dojo.query("img", this)[0]); }); The parent() is a <td>, and the .star is a span. I want to add the hover image whenever the user hovers the table cell. It works as long as the cursor doesn't hover the image, because that will result in some serious blinking. Is this deliberate? And is there a way around it?

• Algorithm - combine multiple lists, resulting in unique list and retaining order

  - by hitch

  I want to combine multiple lists of items into a single list, retaining the overall order requirements. i.e.: 1: A C E 2: D E 3: B A D result: B A C D E above, starting with list 1, we have ACE, we then know that D must come before E, and from list 3, we know that B must come before A, and D must come after B and A. If there are conflicting orderings, the first ordering should be used. i.e. 1: A C E 2: B D E 3: F D result: A C B D E F 3 conflicts with 2, therefore requirements for 2 will be used. If ordering requirements mean an item must come before or after another, it doesn't matter if it comes immediately before or after, or at the start or end of the list, as long as overall ordering is maintained. This is being developed using VB.Net, so a LINQy solution (or any .Net solution) would be nice - otherwise pointers for an approach would be good.

• Line numbering in Visual Studio

  - by Cyclone

  Why doesn't VS have any sort of line numbering? Is there any way to enable it, or a plugin for it? I know, the number of lines of code in a program doesn't matter, but sometimes it is nice to know how long a program is, or what line number something is for reference. I can't seem to find that as an option anywhere, to my surprise. Thanks for the help! This is Visual Studio 2010 Ultimate. (if you have read my older questions, I've been using 2008 Express until now.)

• Set a script to automatically detect character encoding in a plain-text-file in Python?

  - by Haidon

  I've set up a script that basically does a large-scale find-and-replace on a plain text document. At the moment it works fine with ASCII, UTF-8, and UTF-16 (and possibly others, but I've only tested these three) encoded documents so long as the encoding is specified inside the script (the example code below specifies UTF-16). Is there a way to make the script automatically detect which of these character encodings is being used in the input file and automatically set the character encoding of the output file the same as the encoding used on the input file? findreplace = [ ('term1', 'term2'), ] inF = open(infile,'rb') s=unicode(inF.read(),'utf-16') inF.close() for couple in findreplace: outtext=s.replace(couple[0],couple[1]) s=outtext outF = open(outFile,'wb') outF.write(outtext.encode('utf-16')) outF.close() Thanks!

• Content-Length header not returned from Pylons response

  - by Evgeny

  I'm still struggling to Stream a file to the HTTP response in Pylons. In addition to the original problem, I'm finding that I cannot return the Content-Length header, so that for large files the client cannot estimate how long the download will take. I've tried response.content_length = 12345 and I've tried response.headers['Content-Length'] = 12345 In both cases the HTTP response (viewed in Fiddler) simply does not contain the Content-Length header. How do I get Pylons to return this header? (Oh, and if you have any ideas on making it stream the file please reply to the original question - I'm all out of ideas there.)

• Hibernate: same generated value in two properties

  - by Markos Fragkakis

  Hi, I have an entity A with fields: aId (the system id) bId I want the first to be generated: @Id @Column(name = "PRODUCT_ID", unique = true, nullable = false, precision = 12, scale = 0) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "PROD_GEN") @BusinessKey public Long getAId() { return this.aId; } I want the bId to be initially exactly as the aId. One approach is to insert the entity, then get the aId generated by the DB (2nd query) and then update the entity, setting the bId to be equal to aId (3rd query). Is there a way to get the bId to get the same generated value as aId? Note that afterwards, I want to be able to update bId from my gui. If the solution is JPA, even better.

• Improve my Haskell implementation of Filter

  - by mvid

  I have recently been teaching myself Haskell, and one of my exercises was to re-implement the filter function. However, of all the exercises I have performed, my answer for this one seems to me the most ugly and long. How could I improve it? Are there any Haskell tricks I don't yet know? myfilter :: (a -> Bool) -> [a] -> [a] myfilter f (x:xs) = if f x then x : myfilter f xs else myfilter f xs myfilter _ [] = [] Thank You

• VB.NET: Scrollbar "button"?

  - by Omega

  I plan on using a scrollbar for, well, scrolling an image. The image is 200x500, however, the only visible area is 200x250. So I set the max value to 250, and the min value to 0. The idea is that if I drag the scrollbar's button to the bottom, 250 pixels will have moved for the image, right? But wait, the scrollbar's button is.... very small. And the scrollbar is actually pretty long. Is there a way to make the scrollbar's button longer?

• Groovy: stub typed reference

  - by Don

  Hi, I have a Groovy class similar to class MyClass { Foo foo } Under certain circumstances I don't want to initialize foo and want to stub out all the calls to it. Any methods that return a value should do nothing. I could do it like this: Foo.metaClass.method1 = {param -> } Foo.metaClass.method2 = { -> } Foo.metaClass.method3 = {param1, param2 -> } While this will work, it has a couple of problems Tedious and long-winded, particularly if Foo has a lot of methods This will stub out calls to any instance of Foo (not just foo) Although Groovy provides a StubFor class, if I do this: this.foo = new groovy.mock.interceptor.StubFor(Foo) I get a ClassCastException at runtime. Although this would work if I could redefine foo as: def foo But for reasons I won't go into here, I can't do that. Thanks, Don

• A maximum character limit on the preg functions?

  - by animuson

  On my site I use output buffering to grab all the output and then run it through a process function before sending it out to the browser (I don't replace anything, just break it into more manageable pieces). In this particular case, there is a massive amount of output because it is listing out a label for every country in the database (around 240 countries). The problem is that in full, my preg_match functions seems to get skipped over, it does absolutely nothing and returns no matches. However, if I remove parts of the labels (no particular part, just random pieces to reduce characters) then the preg_match functions works again. It doesn't seem to matter what I remove from the label, it just seems to be that as long as I remove so many characters. Is there some sort of cap on what the preg functions can handle or will it time out if there is too much data to be scanned over?

• Open an Access database and run one of its Macros from Excel

  - by sqlnoob

  From Excel, I need to open an Access database and run one of the database's macros. I'm using Excel and Access 2007. Here is my code in Excel: Sub accessMacro() Dim appAccess As New Access.Application Set appAccess = Access.Application appAccess.OpenCurrentDatabase "C:\blah.mdb" appAccess.Visible = True appAccess.DoCmd.RunMacro "RunQueries.RunQueries" appAccess.CloseCurrentDatabase End Sub In the Access Database, there is a procedure named RunQueries in a module named RunQueries. Each time I run this, I get the following error: Runtime error '2485': Microsoft Access Office can't find the object 'RunQueries.' I have also tried: appAccess.DoCmd.RunMacro "RunQueries" and I get the same errors message. Any idea how to do this? By the way, I could go into a long explanation about why I need to do this, but let me just say that I've already argued against it, and I have to do it this way (meaning, I have to use Excel as a frontend to open several Access dbs and run their macros).

• Connection to DB2 in Python

  - by Mestika

  Hi, I'm trying to create a database connection in a python script to my DB2 database. When the connection is done I've to run some different SQL statements. I googled the problem and has read the ibm_db API (http://code.google.com/p/ibm-db/wiki/APIs) but just can't seem to get it right. Here is what I got so far: import sys import getopt import timeit import multiprocessing import random import os import re import ibm_db import time from string import maketrans query_str = None conn = ibm_db.pconnect("dsn=write","usrname","secret") query_stmt = ibm_db.prepare(conn, query_str) ibm_db.execute(query_stmt, "SELECT COUNT(*) FROM accounts") result = ibm_db.fetch_assoc() print result status = ibm_db.close(conn) but I get an error. I really tried everything (or, not everything but pretty damn close) and I can't get it to work. I just need to make a automatic test python script that can test different queries with different indexes and so on and for that I need to create and remove indexes a long the way. Hope someone has a solutions or maybe knows about some example codes out there I can download and study. Thanks Mestika

• Get latitude and longitude using map interface

  - by Dave Jarvis

  Problem Allow website users to enter four latitude and longitude coordinates. Proposed Solution Integrate Google Maps API, and add a click event handler, similar to: http://itouchmap.com/latlong.html http://stackoverflow.com/questions/2770421/how-retrieve-latitude-and-longitude-via-google-maps-api http://marcgrabanski.com/article/jquery-google-maps-tutorial-basics The data would populate into a hidden form field. Questions What other ways (besides <input type='text' ... />) outside of Google's API are available to solve the problem? How would you restrict the number of lat/long points the user can choose? Would using those coordinates violate Google's Terms of Service? Thank you!

• Creating many new instances vs reusing them?

  - by Hugo Riley

  I have multiple business entities in VB.NET Windows Forms application. Right now they are instanced on application startup and used when needed. They hold descriptions of business entities and methods for storing and retrieving data. To cut the long story short, they are somewhat heavy objects to construct (they have some internal dictionaries and references to other objects) created and held in one big global variable called "BLogic". Should I refactor this so that each object is created when needed and released when out of scope? Then every event on UI will probably create a few of this objects. Should I strive to minimize creation of new objects or to minimize number of static and global objects? Generally I am trying to minimize the scope of every variable but should I treat this business logic objects specially?

• Perform Grouping of Resultset in Code

  - by NinjaBomb

  Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it?

• Tortoise SVN revision history

  - by rahul

  I want to know for how long the tortoise svn keeps the revision history. Say I have a file which I deleted from repository through repo browser an year ago, will I be able to still recover that file? If I am able to recover, I also want to know the method to permanently delete that earlier copy of file and related revisions history so that in future nobody is able to access that file. Is it possible? I have run into problems in my organisation as I did frequent updations and deletions assuming that file was getting deleted permanently. The file system of repository has bloated now. Please suggest how to fix it.

• memory problem with metapost

  Hi, I'm using gnuplot to plot a graph to the mp format and then I'm converting it to eps via the command: mpost --sprologues=3 -soutputtemplate=\"%j-%c.eps\" myfigu.mp But I don't get the eps output; instead I get this message: This is MetaPost, version 1.208 (kpathsea version 3.5.7dev) (mem=mpost 2009.12.12) 6 MAY 2010 23:16 **myfigu.mp (./myfigu.mp !

The text file containing these two column values is about 6 MB. Thanks a lot...

• How to programmatically fill a database

  - by Dwaine Bailey

  Hi There, I currently have an iPhone app that reads data from an external XML file at start-up, and then writes this data to the database (it only reads/writes data that the user's app has not seen before, though) My concern is that there is going to be a back catalogue of data of several years, and that the first time the user runs the app it will have to read this in and be atrociously slow. Our proposed solution is to include this data "pre-built" into the applications database, so that it doesn't have to load in the archival data on first-load - that is already in the app when they purchase it. My question is whether there is a way to automatically populate this data with data from, say, an XML file or something. The database is in SQLite. I would populate it by hand, but obviously this will take a very long time, so I was just wondering if anybody had a more...programmatic solution...

• Basic question about request queues in IIS / ASP.Net

  - by larryq

  I have an ASP.Net application running under IIS 6. A simple page has two radio buttons and a submit button. If I select radio button "A" and submit the page, a lengthy PDF file is generated, which takes about a minute to build. If I select radio button "B", a small PDF is generated. (In both cases the PDF is written out to the Response object and it opens in my browser.) If I select radio button "A" and submit, then hit the red X in my browser to stop the current request, then select radio button "B" and resubmit, the page still takes a long time to process my request. No doubt my first request is still being processed on the server, but I was wondering how IIS and/or ASP.Net are queuing my requests so that fair server use is guaranteed among all users. Am I roughly correct in assuming something like this happens, and if so, how is it done?

• Where to open sessions in a Spring/Hibernate stack?

  - by CaptainAwesomePants

  I'm trying to figure out a good design for a Spring/Hibernate app. When creating such an app, it appears like there are a handful of major decisions. The first major decision seems to be where to put the session/transaction boundary. It seems like I have 3 major choices: as a filter before controllers are even invoked, immediately below the controllers at the service call level, and stuffed way below the business level in repository calls. It seems to me like the right call is the middle path, but I'm not sure. I don't want my transactions open too long, but at the same time, I don't want to constantly worry about detached objects and lazy loading in the business logic. Still, there are some downsides. For instance, it makes it hard for the business logic to make a remote call without holding up a transaction for a few seconds. I wonder if there's a better way?

• PHP object parent/child recursion

  - by Damien

  I've got a parent-child OO relationship. Parent obejcts has many child objects and every child object knows about it's parent by reference. The parent can be a child too (basically its a tree). When i do a var_dump() on the root object it says ["parent"]=RECURSION many times and the generated description will be really long. I'm wondering if i do something wrong. If yes, i'm interested in the "best practice". Thanks for the help!

• How to determine what in my script is blocking my HTML rendering?

  - by Vicki

  I have a web application that uses quite a bit of JavaScript. When the page loads, it's very clear visually that something is blocking the rendering of a particular portion of the web site. This portion is generated by a Tabber Tabify JavaScript library. How can I determine what's blocking the HTML rendering specifically so that I can modify my code to prevent this blocking? Can I use Firebug, or some other tool, to walk through my HTML/JavaScript to determine where the HTML rendering is being blocked and if so, how? UPDATE: YSlow gives my web-application a score of "A" and Page Speed give a score of 94/100. UPDATE 2: The live site is linked below. http://www.uptownelite.com/index.uncompressed.html?city=Dallas,TX What I'm specifically referring too is the actual Tabs themselves being rendering (and NOT the panel content inside the tab panes). It seems strange to me that the Tab headings themselves are taking so long to generate on the first (empty cache) page load.
