• Working in consulting company

  - by MichaelT

  I working for some numbers of years in an medium size ecomerce company where we developing and maintaining large distributed ecomerce system that is a core of company business. I thinking to switch job and one of the offers is in consulting company, the model of work there is different you suppose to work for couple of months at different clients of this company developing different project, this mode of working is very different for me and I don't sure if I will like it. From the positive side I will get experience in a lot of different projects in very different problem domains and with a lot of different technologies. From the negative side, I will always be an outsider in all this companies, placed in some far away corner I probably will have little emotional connection to projects I suppose to work on. Do you have some personal experience working in both of this types of companies that you could share ?

• Dialing a command prefix on the iPhone

  - by tewha

  Our application lets users call phone numbers. Users would like to be able to block their caller ID. On other platforms, we let the user specify a custom dialing prefix. For instance, on my cell provider it's #31#. I've tried two approaches so far. First: id url = [NSURL URLWithString: @"tel:#31#0000000"] // produces nil Second: id encoder = ["#31#0000000" stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]; // produces %2331%230000000 id url = [NSURL URLWithString: [NSString stringWithFormat: @"tel:%@", encoded]]; // produces a valid-looking NSURL which doesn't do anything I'm thinking at this point that I'm just not allowed to dial # and *, even from a Cocoa touch application. (I know it's not allowed from a web app.) Is this true, or am I missing something obvious?

• How can I convert convert docx or wordml xml files to xsl-fo?

  - by Jon Pastore

  I've been looking for a method to convert docx or wordml xml to xsl-fo. I read this post: http://stackoverflow.com/questions/156683/what-is-the-best-xslt-engine-for-perl but I'm having exceptional problems getting apache-fop going. I was able to download the bins and run it locally but the formatting was a little off and it didn't maintain the headers and footers or section 1 or section 3 (17 page doc 3 sections) it also overlapped the text over the outline numbers and did not maintain the font used. trying a more simple test caused fop to fail completely. I would like to find a way to create a PDF that is at least close to 100% accurate reproduction of the original doc.

• Partial match in MaskFormatter for jFormattedTextField

  - by Toto

  How do I set up the MaskFormatter and the JFormattedTextField in order to allow partial matches? For example: I want the user to be able to enter numbers with this mask "## ###### ####", so if the user enters '123456789123' the formatter changes it to '12 345678 9123'. However, I also want the user to be able to enter '12346578', be converted to '12 345678' and still be a valid value (so I can get it using jFormatedTextField1.getValue()) This is part of my code (most of it generated by Netbeans): private javax.swing.JFormattedTextField jFormattedTextField1; // ... try { jFormattedTextField1.setFormatterFactory(new DefaultFormatterFactory(new MaskFormatter("## ###### ####"))); } catch (java.text.ParseException ex) { ex.printStackTrace(); } I've tried setting the focusLostBehavior to PERSIST so the value is not cleard after exiting the jFormattedTextField1, but that way I get a null when using the calling jFormattedTextField1.getValue()

• PHP: why uniqid returned value is only 13 digits long

  - by Marco Demaio

  uniqid() function returns a 13 digits long hexadecimal number. According to the spec in php.net site, the function uses microtime to generate the unique value. But microtime returns numbers in string format as the following one: "0.70352700 12689396875" which are basically the microseconds and the seconds elapsed since 1970. This is a 9+11 digits decimal number. Converting a 20 decimal number into hex would result in a 16 digits hexadecimal NOT a 13 digits one. I also thought to take out the "0." part that seem to never change, and the last two digits of the microsec part that seem to remain always "00". Doing this the decimal number would be only 9+11-3 digits long, but still a decimal number of 17 digits when converted into hex would result in 14 digits hexadecimal number NOT 13. You probably think I'm crazy in asking such a thing, but I'm concerned about using uniqid, unique values are important to be unique, a duplicated value could screw up an entire application.

• A device specific alpha bitmap fails after switching resolutions in remote desktop

  - by Bob

  All my alpha bitmaps, created using CreateCompatibleBitmap(..), start to receive an error code 87 after someone signs in with Remote Desktop. I am assuming that this is because the resolution changed and I am using a device specific bitmap. I am wondering what the best route is to fix this issue without migrating to a device independent bitmap? Some options are: 1) Detect remote desktop change and flag all bitmaps to be reloaded (I have done this but it does not work as well as I would like). 2) Wait for error code 87 to happen on an alphablend image that previously worked, and then reload it (was going to try this next, im sure it will work, but a little hacky) 3) Detect random event such as WM_DISPLAYCHANGE or _ that tells me when I should do this (ie: a device change event I'm guessing, or maybe something more specific?) 4) _? Thanks for any help in advance

• Xpath to get the 2nd url with the matching text in the href tag

  - by Blankman

  A html page has paging links, 1 set at the top of the page and another on the bottom of the page. Using HtmlUnit, I am currently getting the HtmlAnchor on the page using getByAnchorText("1"); There is a problem in some of the links on the top, so I want to reference the bottom links using XPath. nextPageAnchor = (HtmlAnchor) page.getByXPath(""); How can I reference the 2nd link on the page, with using xpath? I need to reference the link using the AnchorText, so a link like: <a href="....">33</a> The href has random text, and is a javascript function so I have no idea what it will be. Is this possible with xpath?

• Access 2007 VBA : Building a listbox with selection choices from another list box

  - by Justin

  So there are 8 categories that may be associated to each order, but not necessarily all of them. So i was going to build a list box that allowed the user to double click each of the category they wish to associate when they have an "Order Detail" form opened up (unbound form that has hidden text boxes with all needed ID numbers). I want to have another empty text box right beside it that will allow me to append the selections (up to 8) so the user can see that they have been added. So one list box with the default choices, and when a choice is double clicked, it adds that choice to the second list box to see the tally so to speak. What is the VB for getting something like this done? Thanks Justin

• Looking to capture PageIndex on a gridview

  - by StevieB

  Hey, So I have a gridview which lists a bunch of jobs. On this gridview I have paging enabled, which works fine. When I hover over the Page Numbers i.e 1,2,3,4,.... the following is displayed javascript_DoPostBack('C100PlaceHolderGrievew','Page$1') Now my problem is as follows. When I click on one of the hyperlinks in this list i go to an edit details page. Once the user clicks on save I redirect the user back to the List page with gridview. What I would like to implement is that the gridview remembers what page they came from i.e Page 2. I know i can Use PageIndex to set this but Im not sure how to send across the value of "page" of the gridview so i can this.

• BigInteger or not BigInteger?

  - by Alon

  In Java, most of the primitive types are signed (one bit is used to represent the +/-), and therefore when I am exceed the limits of this type, I can get many strange things, like negative numbers. In the BigInteger class, I have no limits and there are some helpful functions there but it is pretty depressing to convert your beautiful code to work with the BigInteger class, specially when primitive operators don't work there and you must use functions from this class. I was wondering if you had this problem, and if you have any better solution than the BigInteger class? Thank you.

• Blackberry ESS standalone mode && Outlook 2007

  - by new Blackberry developer

  Hi, I launch Blackberry ESS in standalone mode. However I don't have Outlook Express on my computer. Instead I have Outlook 2007 on my computer. I set up an email account in Outlook 2007 which uses 'localhost' as its pop3/smtp server. The port numbers I used are the same as those in http://www.blackberryforums.com/developer-forum/5590-sending-receiving-email-device-simulator.html. However I got the following exception. 'UnknownHostException:pop3.server'. I am wondering if Outlook 2007 works with ESS.

• How long does it take to iterate through a long loop?

  - by Carl Rosenberger

  On a modern 64-Bit machine, how long do you think it takes to iterate through all the positive long numbers? Below is a code snippet in Java to demonstrate the idea. Without running the code yourself, how long do you think this code is going to run? How long will similar code run in other programming languages? public class LongLoop { public static void main(String[] args) { long startTime = System.currentTimeMillis(); for (long i = 0; i < Long.MAX_VALUE; i++) { // do nothing, just loop } long stopTime = System.currentTimeMillis(); long duration = stopTime - startTime; System.out.println("Time taken: " + duration + " milliseconds"); } }

• C# Custom Dictionary Take - Convert Back From IEnumerable

  - by Goober

  Scenario Having already read a post on this on the same site, which didn't work, I'm feeling a bit stumped but I'm sure I've done this before. I have a Dictionary. I want to take the first 200 values from the Dictionary. CODE Dictionary<int,SomeObject> oldDict = new Dictionary<int,SomeObject>(); //oldDict gets populated somewhere else. Dictionary<int,SomeObject> newDict = new Dictionary<int,SomeObject>(); newDict = oldDict.Take(200).ToDictionary(); OBVIOUSLY, the take returns an IENumerable, so you have to run ToDictionary() to convert it back to a dictionary of the same type. HOWEVER, it just doesn't work, it wants some random key selector thing - or something? I have even tried just casting it but to no avail. Any ideas?

• Evenly select N elems from array

  - by ninuhadida

  Hi, I need to evenly select n elements from an array. I guess the best way to explain is by example. say I have: array [0,1,2,3,4] and I need to select 3 numbers.. 0,3,4. of course, if the array length <= n, I just need to return the whole array. I'm pretty sure there's a defined algorithm for this, been trying to search, and I took a look at Introduction to algorithms but couldn't find anything that met my needs (probably overlooked it) The problem I'm having is that I can't figure out a way to scale this up to any array [ p..q ], selecting N evenly elements. note: I can't just select the even elements from the example above.. A couple other examples; array[0,1,2,3,4,5,6], 3 elements ; I need to get 0,3,6 array[0,1,2,3,4,5], 3 elements ; I need to get 0, either 2 or 3, and 5

• JavaScript Intellisene Problem?

  - by James Wiseman

  I've got an issue with JavaScript intellisense in Visual Web Developer 2008, which I'm starting to believe is "just one of those things", but thought I'd ask here just to check. I have a file MyOtherFile.js with a function GetRandomNumber() defined like so: function GetRandomNumber() { /// <summary> /// Summary description for GetRandomNumber /// </summary> return Math.random(); } When I reference this from another file, screen.js (/// <reference path="MyOtherFile.js" />) I get the intellisense as expected with the summary text as above. If, however, I call the function GetRandomNumber from within its own file (MyOtherFile.js) then I don't get the sumamry description. Any thoughts? Thanks.

• Setting a cell's format using Excel 2007 Interop and C#

  - by CVertex

  I'm using the office 2007 interop assemblies to create some excel spreadsheets. There are plenty of questions on here about getting started and MSDN contains heaps of articles, like this one. The API is funky, and sometimes a bit confusing. When I set a value of a cell, is there a way to set it's format? I'd like to mark particular fields as Date's so my customer can run excel macros on them. Also, numbers would be useful. Thanks!

• problem plotting on logscale in matplotlib in python

  - by user248237

  I am trying to plot the following numbers on a log scale as a scatter plot in matplotlib. Both the quantities on the x and y axes have very different scales, and one of the variables has a huge dynamic range (nearly 0 to 12 million roughly) while the other is between nearly 0 and 2. I think it might be good to plot both on a log scale. I tried the following, for a subset of the values of the two variables: fig = plt.figure(figsize(8, 8)) ax = fig.add_subplot(1, 1, 1) ax.set_yscale('log') ax.set_xscale('log') plt.scatter([1.341, 0.1034, 0.6076, 1.4278, 0.0374], [0.37, 0.12, 0.22, 0.4, 0.08]) The x-axes appear log scaled but the points do not appear -- only two points appear. Any idea how to fix this? Also, how can I make this log scale appear on a square axes, so that the correlation between the two variables can be interpreted from the scatter plot? thanks.

• std::map operator[] and automatically created new objects

  - by thomas-gies

  I'm a little bit scared about something like this: std::map<DWORD, DWORD> tmap; tmap[0]+=1; tmap[0]+=1; tmap[0]+=1; Since DWORD's are not automatically initialized, I'm always afraid of tmap[0] being a random number that is incremented. How does the map know hot to initialize a DWORD if the runtime does not know how to do it? Is it guaranteed, that the result is always tmap[0] == 3?

• A cross between std::multimap and std::vector?

  - by Milan Babuškov

  I'm looking for a STL container that works like std::multimap, but has constant access time to random n-th element. I need this because I have such structure in memory that is std::multimap for many reasons, but items stored in it have to be presented to the user in a listbox. Since amount of data is huge, I'm using list box with virtual items (i.e. list control polls for value at line X). As a workaround I'm currently using additional std::vector to store "indexes" into std::map, and I fill it like this: std::vector<MMap::data_type&> vec; for (MMap::iterator it = mmap.begin(); it != mmap.end(); ++it) vec.push_back((*it).second); But this is not very elegant solution. Is there some such containter?

• strod() and sprintf() inconsistency under GCC and MSVC

  - by Dmitry Sapelnikov

  I'm working on a cross-platform app for Windows and Mac OS X, and I have a problem with two standard C library functions: strtod() (string-to-double conversion) ? sprintf (when used for outputting double-precision floating point numbers) -- their GCC and MSVC versions return different results. I'm looking for a well-tested cross-platform open-source implementation of those functions, or just for a pair of functions that would correctly and consistently convert double to string and back. I've already tried the clib GCC implementation, but the code is too long and too dependent on other source files, so I expect the adaptation to be difficult. What implementations of string-to-double and double-to-string functions would you recommend?

• NHybernate, the Parallel Framework, and SQL Server

  - by andy

  hey guys, we have a loop that: 1.Loops over several thousand xml files. Altogether we're parsing millions of "user" nodes. 2.In each iteration we parse a "user" xml, do custom deserialization 3.finally, in each iteration, we send our object to nhibernate for saving. We use: .SaveOrUpdateAndFlush(user); This is a lengthy process, and we thought it would be a perfect candidate for testing out the .NET 4.0 Parallel libraries. So we wrapped the loop in a: Parallel.ForEach(); After doing this, we start getting "random" Timeout Exceptions from SQL Server, and finally, after leaving it running all night, OutOfMemory unhandled exceptions. I haven't done deep debugging on this yet, but what do you guys think. Is this simply a limitation of SQL Server, or could it be our NHibernate setup, or what? cheers andy
