• How to use a custom Windows 7 system drive letter?

  - by Ivan

  The subject PC has many hard drive partitions dedicated for different purposes, C: being a Windows XP system drive and F: (which is actually the next primary partition placed right after C: physically) being intended to host a newly installed Windows 7 instance (meant for "dual boot" configuration). Needless to say the intention was all the partitions to have exactly the same letters under both OSes, needless to say Windows 7 has detected all of them in a completely different order which would not be a problem (as the non-system drives letters can be changed easily after installation) if it wouldn't have named it's system drive C: (meant to be F:), which I have no Idea how to change. Is there a way to set the letter you want? I don't mind reinstalling Windows 7 from scratch if it is to be set at installation time or even configured in some text files on the installation DVD. I have tried this way, but it renders the Windows 7 system desktop unbootable (gets stuck on "Preparing your desktop..." after "Welcome").

• opening offline sync files from a .CAB file

  - by Rob

  OK, I have downloaded from Windows Live Spaces (don't know if this is useful, but might be) a .CAB file containing an Index.XML file and package.cab, package01.cab through to package12.cab. The index.XML simply has names of all the subsequent package.cab files and their offsets. The first package.cab has a single 26MB XML file which appears to be an OfflineSyncFile definition which I am guessing is the meta data for all the other packageXX.cab files. Now the question I have is how should i be going about extracting these things and piecing it all back together again. I have tried WinRAR, which extracts all 800MB for me into unnamed files and randomly named directories. I have also tried the standard extract in Windows Explorer with much the same resusts.

• How can I tag sequences inside videos?

  - by Antoine

  For example, let's say I find a sequence in a WWDC session (Apple videos) that explains a technical point very well. I would like to be able to store the exact range in the video, tag it with keywords, and manage all that information. And when I want to share this information, I could simply export to a plain English sentence: "Have a look at the video named …". It would be great to be able to launch a video player for local videos and go straight to the beginning of the sequence.

• Exchange Server Contact Categories - How to Remove/Update All

  - by ben

  I've been tasked with cleaning up our companies contact database sitting on our Exchange Server 2003. The rub is this database of contacts has been neglected for the past couple of years and is now a bit messy. My issue is I have say a person named 'Bob Smith', and Bob is listed in multiple categories, 'Students' and 'Student'. I would really like to remove the 'Student' category from Bob and anyone else out there that has the same category. My question is, is there an easy way to edit the master category lists for contacts on the exchange server? I feel like I am missing something simple here since if I were playing with the categories that I use, to say organize email its very easy to do so, but I can't seem to find the proper way to do it for categories that are up on the server. I'm attempting to work through Outlook 2007 and Exchange 2003. Any insight would be very helpful as I really don't want to change 8000+ contacts by hand.

• Escaping query strings with wget --mirror

  - by Jeremy Banks

  I'm using wget --mirror --html-extension --convert-links to mirror a site, but I end up with lots of filenames in the format post.php?id=#.html. When I try to view these in a browser it fails, because the browser ignores the query string when loading the file. Is there any way to replace the ? character in the filenames with something else? The answer of --restrict-file-names=windows worked correctly. In conjunction with the flags --convert-links and --adjust-extension/-E (formerly named --html-extension, which also works but is deprecated) it produces a mirror that behaves as expected. wget --mirror --adjust-extension --convert-links --restrict-file-names=windows http://www.example

• XSLT: a variation on the pagination problem

  - by MarcoS

  I must transform some XML data into a paginated list of fields. Here is an example. Input XML: <?xml version="1.0" encoding="UTF-8"?> <data> <books> <book title="t0"/> <book title="t1"/> <book title="t2"/> <book title="t3"/> <book title="t4"/> </books> <library name="my library"/> </data> Desired output: <?xml version="1.0" encoding="UTF-8"?> <pages> <page number="1"> <field name="library_name" value="my library"/> <field name="book_1" value="t0"/> <field name="book_2" value="t1"/> </page> <page number="2"> <field name="book_1" value="t2"/> <field name="book_2" value="t3"/> </page> <page number="3"> <field name="book_1" value="t4"/> </page> </pages> In the above example I assume that I want at most 2 fields named book_n (with n ranging between 1 and 2) per page. Tags <page> must have an attribute number. Finally, the field named library_name must appear only the first <page>. Here is my current solution using XSLT: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" exclude-result-prefixes="trx xs"> <xsl:output method="xml" indent="yes" omit-xml-declaration="no" /> <xsl:variable name="max" select="2"/> <xsl:template match="//books"> <xsl:for-each-group select="book" group-ending-with="*[position() mod $max = 0]"> <xsl:variable name="pageNum" select="position()"/> <page number="{$pageNum}"> <xsl:for-each select="current-group()"> <xsl:variable name="idx" select="if (position() mod $max = 0) then $max else position() mod $max"/> <field value="{@title}"> <xsl:attribute name="name">book_<xsl:value-of select="$idx"/> </xsl:attribute> </field> </xsl:for-each> <xsl:if test="$pageNum = 1"> <xsl:call-template name="templateFor_library"/> </xsl:if> </page> </xsl:for-each-group> </xsl:template> <xsl:template name="templateFor_library"> <xsl:for-each select="//library"> <field name="library_name" value="{@name}" /> </xsl:for-each> </xsl:template> </xsl:stylesheet> Is there a better/simpler way to perform this transformation?

• Parsing boolean from configuration section in web.config

  - by Bloopy

  I have a custom configuration section in my web.config. One of my classes is grabbing from this: <myConfigSection LabelVisible="" TitleVisible="true"/> I have things working for parsing if I have true or false, however if the attribute is blank I am getting errors. When the config section tries to map the class to the configuration section I get an error of "not a valid value for bool" on the 'LabelVisible' part. How can I parse "" as false in my myConfigSection class? I have tried this: [ConfigurationProperty("labelsVisible", DefaultValue = true, IsRequired = false)] public bool? LabelsVisible { get { return (bool?)this["labelsVisible"]; } But when I try and use what is returned like so: graph.Label.Visible = myConfigSection.LabelsVisible; I get an error of: 'Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) Thanks for any suggestions!

• Crystal Reports Legends

  - by AWinters

  Is there a way to force a Bar Chart legend in Crystal Report 11.5 to display its objects in a particular order? For Example, say I am reporting on the consumption of "Bananas" and "Apples" by State. The Bar Chart should display the percentage of people who eat these fruits by county (Percent Bar Chart). The "Apples" percentage always displays on top of the bar chart and the "Bananas" on the bottom. The legend for this graph also displays the "Apple" color first, then the "Banana" color. However, if the "Banana" percentage is 0% the legend displays the "Banana" color first on the legend. This creates a inconsistent report (with plenty of complaints). I would like the "Banana" color to always display second in the legend. Hope I didn't confuse anyone and any ideas would be helpful.

• jquery - loose click() event after ajax call ???

  - by niczoom

  At the following webpage liamharding.com/pgi.php I have an option panel on the left side of the page which opens and close's upon clicking the panels 'arrow', this works fine until you select a market (for testing use one of the 'Random Walk' markets and click 'Show/Refesh Graphs'), this then makes an ajax call using get_graph(forexName, myCount, divIsNew) function. Once this call is completed a graph(s) is displayed and then my options panels click() event does not work? The ajax call returns the data in a variable ajax_data, the problem happens when I perform the following code var jq_ajax_data = $("<div/>").html(ajax_data); . I need to wrap it in a so I can extract data from it using jQuery. If this line of code is commented out the click() event works fine ?? Hope somebody can help, I have spent a lot of time but cant find what the problem is.

• Get status of servlet request before the response is returned

  - by Alex

  Good evening, I am in the process of writing a Java Servlet (Struts 2, Tomcat, JSP etc) which is capable of doing some fairly complex simulations. These can take up to 2 minutes to complete on the and will return a graph of the results. It is trivial to calculate the percentage of the simulation completed because the process works by repeating the same calculations 1000s of times. I would be interested to know if anyone has ever tried to use client side technology to provide any estimate of the percentage complete. I.e query the servlet processing to get the number of cycles completed at various point throughout the simulation. This could then be displayed as a bar in the client browser. Any thoughts, advice, resources would be much appreciated. Thanks, Alex

• Deploy Windows 7 Backup set to Windows 8

  - by Matthias

  Situation: We have a laptop here that's completely fubar. I.e: The hard drive is filled to the brim with bad sectors. Luckily, backups have been made using the built-in Windows 7 backup feature. This produces folders named Backup Set 2012-11-09 003009, containing folders like Backup Files 2012-11-09 003009, containing zip-files like Backup files 1, 2, 3,... Our brand new laptop comes with Windows 8. Now: Can we, using the standard back-up and restore feature in Windows 8, restore all the documents, music, etc. using the Windows 7 backup files? Thanks. (FYI: We also took a normal backup of all the documents just to be sure of course. I'm just curious what would happen. I would test it out, but the new laptop hasn't arrived yet and I wanted to make sure my efforts would not be in vain.)

• Setting Redmine path

  - by David Parunakian

  Hello, How can I set the path on which Redmine should be run, e.g. example.com:3000/redmine instead of example.com:3000? There is an appropriately named option in the settings panel, but it serves a different purpose, according to the documentation and experimental observations (it is used to write URL in emails sent to users). A wider picture: I need this in order to properly serve Redmine on port 80 over Apache's mod_proxy (i.e. at example.com/redmine). The problem is that when running it on /, the home page fails to load the necessary resources (such as JavaScript and CSS files). Any workarounds?

• Ant 1.8 include or import with nested resource collection

  - by Danny

  I'd like to have Ant automatically include or import resources matching a particular pattern, but I'm really struggling with the syntax. Here's what I've tried: <import> <fileset dir="${basedir}" includes="*-graph.xml" /> </import> However, I just get the error message import requires file attribute or at least one nested resource The documentation for import (and include) both say that you can use a nested resource collection, and the documentation for resource collections says <fileset> is a resource collection. I've Googled and can't find any useful examples at all. I'm using Ant 1.8.1 (verified with ant -version)

• AJAX response inside jqplot not working

  - by JuanGesino

  I'm trying to render data from an AJAX response as a bar chart with jqplot. To render this bar chart I use two variables: s1 which contains the numbers ex: s1 = [22,67,32,89] ticks which contains the name corresponding to a number inside s1 ex: ticks = ["Jack", "Mary", "Paul", "John"] So my AJAX returns two variables, data1 and data2. When I console.log(data1) I get 22,67,32,89 When I console.log(data2) I get "Jack", "Mary", "Paul", "John" I then add the square brackets and change variable: s1 = [data1] ticks = [data2] When I console.log(s1) I get ["22,67,32,89"] When I console.log(ticks) I get "Jack", "Mary", "Paul", "John" And the graph does not render, this is my code: s1 = [data]; ticks = [data]; plot4 = $.jqplot('chartdiv4', [s1], { animate: !$.jqplot.use_excanvas, series:[{color:'#5FAB78'}], seriesDefaults:{ renderer:$.jqplot.BarRenderer, pointLabels: { show: true } }, axes: { xaxis: { renderer: $.jqplot.CategoryAxisRenderer, ticks: ticks }, yaxis:{min:0, max:100, label:'%',labelRenderer: $.jqplot.CanvasAxisLabelRenderer} }, highlighter: { show: false } }); });

• Best language to use when exporting an excel file

  - by Aaron

  I want to write a macro program that takes in data from a text file and then arranges it in a specific manner in an excel file. I don't know which language has the best features for dealing with Excel. I prefer java, and I see someone made an api called JExcelApi, but I'm not sure about it's capabilities. I would like to be able to generate a graph automatically in excel based on the data in a certain column. Is this possible in any language? I would guess that Microsoft's VB or C# would have an advanced feature such as this, but I'm not sure. Thanks.

• pitchbend (varispeed) audio with iPhone SDK's AudioUnit

  - by fetzig

  hi, I'm trying to manipulate the speed (and pitch) of a sound while playing. so i played around with iphone sdk's AudioUnit. downloaded iPhoneMultichannelMixerTest and tried to add an AUComponent to the graph (in this case a formatconverter). but i get (pretty soon) following error when building: #import <AudioToolbox/AudioToolbox.h> #import <AudioUnit/AudioUnit.h> ... AUComponentDescription varispeed_desc(kAudioUnitType_FormatConverter, kAudioUnitSubType_Varispeed, kAudioUnitManufacturer_Apple); ^^ error: 'kAudioUnitSubType_Varispeed' was not declared in this scope. any ideas why? the documentation on this topic doesn't help me at all (just api doc isn't very helpful when having no clue about the concept behind). there are no examples on how to wire these effects together and manipulating there properties...so maybe i'm totally wrong, anyway any hint is great. thx for help.

• Virtual PC lost parent disk for differential vhd

  - by SeeR

  2 years ago I had that brilliant idea to create base Windows XP disk which all of my VM with XP will use. Of course it ended that I had only one VM with XP :-). Today I needed to make some free space on my HDD so I found one not used VM named "Windows XP" which had only 5GB. I deleted it as fast as possible :-) and of course I used shift to not use "Recycle bin". Now when I want to run my XP VM I have following error: "One of the parent hard disks of ... is missing." It's not a problem for me as soon as I can restore files from this differential vhd that I have right now. So: I have differential disk with files I need I don't have parent disk My question is: How can I restore files from this differential hvd?

• How to override ggplot2's axis formatting?

  - by Richie Cotton

  When you choose a log scale, ggplot2 formats the breaks like 10^x. I'd like it to not do that. For example, the code below should display a graph with ticks at 1, 2, 5 etc, not 10^0, 10^0.3, 10^0.69 etc. library(ggplot2) dfr <- data.frame(x = 1:100, y = rlnorm(100)) breaks <- as.vector(c(1, 2, 5) %o% 10^(-1:1)) p1 <- ggplot(dfr, aes(x, y)) + geom_point() + scale_y_log10(breaks = breaks) print(p1) I guess that adding a formatter argument to scale_y_log10 would do the trick, but I'm not sure what to put in the argument, or where the options might be documented.

• iPhone + alternative to drop downs

  - by pratik

  Hello, I am developing native iPhone app. I have one requirement that, there are 5 drop downs in the screen, where user will select each value and based on that there will be a graph generated on screen. Also the drop downs are cascading, meaning that depending on value selected in upper drop down, the values in lower drop downs will change. If it was a web app than, I had no problem as we have drop downs available. But it is a native iPhone app and we don't have drop down in iPhone SDK. Please suggest me some other alternative to achieve the same. Regards, Pratik

• OpenVPN Setup - Service Won't Start

• How can i automatically move files based on their name?

  - by Pasha

  I have 13 folders containing scanned photographs. Some photographs have been renamed to the date on which they were taken, resulting in YYYY.MM.DD.tif name. It could potentially be YYYY.MM.DD (###).tif where ### is just a number. Others are just named IMG_###.tif I would like to move the files with the YYYY.MM.DD name to a YYYY\MM\DD folder structure. While the files are being moved, I would also like to append the original folder name to the end of the file name. So, a file 01\2012.06.26 (1).tif should end up 2012\06\26\2012.06.26 (1) - 01.tif Is there a Windows tool that can help me with this? Or do I need to resort to writing a custom app?

• DB auto failover in c# does not work when the principal server physically goes offline

  - by user62521

  I'm setting up DB auto failover in C# with SQL Server 2008 and I have a 'high safety with automatic failover mirror' using a witness setup and my connection string looks like "Server=tcp:DC01; Failover Partner=tcp:DC02; database=dbname; uid=sewebsite;pwd=somerndpwd;Connect Timeout=10;Pooling=True;" During testing, when I turn off the SQL Server service on the principal server the auto failover works like a charm, but if I take the principal server offline (by shutting down the server or killing the network card) auto failover does not work and my website just times out. I found this article where the second last post suggests that its because we are using named pipes which does not work when the principal goes offline, but we force TCP in our connection string. What am I missing to get this DB auto failover working?
