  • Print job leaves queue but document isn't printed

    - by midnightstar
    I'm dealing with an HP Deskjet F380 All-in-One printer. It's connected via USB to a desktop running Windows 7 Enterprise x64. If I attempt to print something like a web page or a word document, the print job will show up in the print queue and the printer would stir. By stir, I mean, it would seem to prepare itself to print. However, the print job would then leave queue (I'm thinking the computer sees it as completed) and the printer would never actually print anything. However I went into Printers and Devices under the Windows start menu, into printer properties, and print a test page, the test page would print out successfully. I attempted to uninstall and re-install the printer drivers for the printer, but the printer would continue the same behavior afterwards. I also connected the printer to another computer and the printer will print just about anything. I also checked to make sure that the computer the printer needs to be connected to was update to date as far as the OS. The machine is fully up to date. I played with the way the computer handles printer spooling. Under the printer properties, under the "Advanced" tab, I had the print job print directly to the printer. In all these instances, the same behavior continues. I've restarted the printer spooling service. I've also gone under C:\Windows\System32\spool\PRINTERS and deleted files that were sitting in the folder. I have ran SFC /scannnow and the system found no errors in the system's integrity. I had the computer and printer make a cold reboot individually. The only lead I really have going for me is that since the printer prints on other PCs, I can only assume that there is something wrong with the way the PC is configured.

  • What character can be safely used for naming files on unix/linux?

    - by Eric DANNIELOU
    Before yesterday, I used only lower case letters, numbers, dot (.) and underscore(_) for directories and file naming. Today I would like to start using more special characters. Which ones are safe (by safe I mean I will never have any problem)? ps : I can't believe this question hasn't been asked already on this site, but I've searched for the word "naming" and read canonical questions without success (mosts are about computer names). Edit #1 : (btw, I don't use upper case letters for file names. I don't remember why. But since a few month, I have production problems with upper case letters : Some OS do not support ascii!) Here's what happened yesterday at work : As usual, I had to create a self signed SSL certificate. As usual, I used the name of the website for the files : www2.example.com.key www2.example.com.crt www2.example.com.csr. Then comes the problem : Generate a wildcard self signed certificate. I did that and named the files example.com.key example.com.crt example.com.csr, which is misleading (it's a certificate for *.example.com). I came back home, started putting some stars in apache configuration files filenames and see if it works (on a useless home computer, not even stagging). Stars in file names really scares me : Some coworkers/vendors/... can do some script using rm find xarg that would lead to http://www.ucs.cam.ac.uk/support/unix-support/misc/horror, and already one answer talks about disaster. Edit #2 : Just figured that : does not need to be escaped. Anyone knows why it is not used in file names?

  • Un-do Windows disk convert HFS+

    - by BLAKE
    Last night, a friend asked my to give him a copy of a word document. He handed me an external hard drive and left. I plugged the hard drive into my file server running Windows Server 2003, opened disk management and clicked OK. (I know that in Windows 2003 you need to manually assign a drive letter to external drives.) I then looked at the drive in disk management and it said that it was unallocated space. I called my friend and he said that there was data on the drive, but he used it with his Mac Book. Aperantly when I clicked OK in disk management I converted the from HFS+ file system to something else. Is there any way to undo the disk convert? I immediately removed the drive, so there was no writing to it. Windows did not format the drive, it just converted it. Is the data still there? All the data recovery programs I have are for windows, can they read the Mac file system? I need to get the data back, what can I do?

  • OpenOffice Vs Microsoft Office 2007/2010

    - by Moody Tech
    I have been asked to summarise the pros and cons in connection with the choices between Microsoft Office Vs OpenOffice. I have a broad idea of what needs to be said. However I would like to open a discussion here and have a single place to go to when the time comes to give the summary to management. There are obvious points of contention: For me the lack of compliance with Group Policy is a major concern [Default save location/visibility of C:/Visibility of files and folders on the HDD] However I am sure that functionality and compatibility will be the prime mover. We are looking at making major savings by reducing our commitment to Microsoft licensing. So what are your experiences? What happens when there are no direct equivalents? [Word has a close match in OpenOffice, but a database solution match is not as close, neither is an Outlook [connecting to Exchange Server and downloading all calendars, shared calendars, scheduled events, for Exchange will still exist after the move to OpenSource solutions] In summary then: What do you see as: The benefits of this plan? How do you see the problems being manifest? Discuss.... Many thanks.

  • Windows 7 Icons, Buttons, and Tabs corrupted...Professional 32-bit

    - by xhyperx
    The other day, about two or three ago, I was simply typing in a Microsoft Word document when my screen froze. After a few moments, it went black...I thought it was my vid hardware (dual nVidia 9800 GTs). Anyway, I did a hard reboot, and chose to Start Normally. The system blue screened telling me there was a failure in the Memory Manager. So then I thought maybe a RAM failure or vid memory failure. I attempted reboot again, this time I got presented with the option to repair windows...so I went with that. The repair app finished and did an auto reboot. This time I got all the way back to my desktop where in a matter of a about 30 seconds, the system blue screened again and pointed to the Memory Manager as the area of cause. Again I rebooted, the repair thingy came up again and I allowed it to do its thing. Deciding if the same failure occured I'd begin pulling hardware to see at what point I may have found the possibly defective party. However, this time it rebooted, I got back to desktop and no crash. All looked well, untill I looked at the baloon messages when hovering over the System Bar icons. Also when I opened any of my browsers, the tabs had no text, and any window that pops up that has regular buttons (OK, Cancel, etc., etc.) looks weird. The buttons are really really long and have no text. So it seems like the system is once again running smoothly, however something has gotten corrupted.. something relating to drawing basic windows user interface objects. Help...all ideas are respected and appreciated. Have a great day everyone!

  • Outlook 2010 search not working after upgrade to windows 8

    - by Klaaz
    After upgrading my computer to Windows 8 Outlook 2010 has stopped displaying search results. Normally you can enter a (part) of a word in the search box on top of the inbox list and it will show you result immediatly. Even mails allready visible on the screen are not found. Somebody familiar with this issue? Update: maybe relevant: I use an Google Apps Pro account. All mail is synced and locally available in Outlook 2010. I did not change this in any way while upgrading, it was working perfectly before. I can scroll through all the e-mails, new mails are coming in as expected. This morning I received two mails from a person by the name of Rosanne. When searching on her name in Outlook it gives me One (1) result, the last mail from today. Update 2: Rebuilding the index seemed to be working. But after another day it stopped working again. No results whatsoever in Outlook search. Rebuilding indexes every day is not an option as it takes several hours. I suspect it has something to do with the fact that I use Google Apps Pro. It acts like a Exchange server to outlook. In indexing options (configuration) I added the directories containg the PST from this service (mail is also synced locally)

  • Is it possible to use different zsh menu selection behaviour for different commands?

    - by kine
    I'm using the menu select behaviour in zsh, which invokes a menu below the cursor where you can see the various possibilities. The .zshrc option i have set for this is zstyle ':completion:*' menu select=2 By default, pressing Return to select a possibility in this menu only completes the word — it does not actually send the command. For example, I might get a menu like this ~ % cd de<TAB> completing directory: [Desktop/] Development/ Pressing Return here will result in ~ % cd Desktop/ I then have to press Return a second time to actually send the command. I can modify this behaviour to make it so that pressing Return both selects the completion and sends the command by doing this bindkey -M menuselect '^M' .accept-line However, there's a problem with this: sometimes I need to complete a file or directory without sending the command. For example, I might need to do ln -s Desktop Desktop2 — with this bindkey behaviour, trying to complete Desktop will result in ln -s Desktop/ being sent as the command, and obviously I don't want that. I'm aware that just pressing space will let me get on with the command, but it's now a habit. Given this, is there a way to make it so that only some commands let you press Return once (like cd), but all other commands require pressing it twice?

  • How to Find Out Who Made an ISO Disk?

    - by Qwertyfshag
    If a file is saved using Microsoft word or some other type of program, you can right click on the file to find the properties, which will indicate the computer that created the file. Is there anyway to find out who created an ISO disk image on a CD or DVD? I assume that there should be no meta data on the disk because an ISO disk image should be an exact duplicate of the original. Is my assumption correct? To illustrate with an example, let's say you found a CD at a cafe or something. You decide to look at the CD with your computer. You find out that it is an "Ubuntu live CD" that was obviously created from an ISO file. Is there any way to find out who burned the CD? Or, on the flip side, let's say you were the one that burned the "Ubuntu live CD" and you lost it. Would somebody be able to know that it was you who made the CD? Can they get any info about the maker?

  • Easiest way to find out if user has either Windows 7 or Vista (through telephone support)?

    - by Rabarberski
    If you have to provide some initial troubleshooting support by phone [or email], and you don't have access to the PC itself, what is the easiest and most foolproof question to find out if the 'dumb' user is using either Windows 7 or Windows Vista? For example: determining if the user has either Windows XP or Windows Vista/7 is easy. Just ask the user if the button at the left bottom corner is (a) either square with the word 'Start' on it, or (b) it is a round button. But how to determine the difference between Vista and 7? Edit: For all the existing answers the user has to type something, and do it correctly. Sometimes even that is already hard for a computer illiterate user. My XP example just requires looking. If it exists (although I am afraid it doesn't), I think a solution that is just based on something this is visually different between Vista and 7 would stand above all others. (Which makes Dan's suggestion to turn over the box and look at the label" not so stupid). Perhaps the small 'show desktop' rectangle at the right side of the task bar (was that present in Vista)?

  • Exporting makefile from Eclipse CDT

    - by Alex Farber
    I have C++ project in the Ubuntu OS, Eclipse CDT. My final goal is to build the project binaries for FreeBSD OS. The first test. I create simple C++ CDT project with main.cpp file: cout << "OK" << endl; and build it. Then I open Terminal window in Release directory: alex@alex-linux:~/workspace/HelloWorld/Release$ ls HelloWorld main.d main.o makefile objects.mk sources.mk subdir.mk alex@alex-linux:~/workspace/HelloWorld/Release$ rm HelloWorld main.d main.o alex@alex-linux:~/workspace/HelloWorld/Release$ ls makefile objects.mk sources.mk subdir.mk alex@alex-linux:~/workspace/HelloWorld/Release$ make Building file: ../main.cpp Invoking: GCC C++ Compiler g++ -O3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o"main.o" "../main.cpp" Finished building: ../main.cpp Building target: HelloWorld Invoking: GCC C++ Linker g++ -o"HelloWorld" ./main.o Finished building target: HelloWorld alex@alex-linux:~/workspace/HelloWorld/Release$ ./HelloWorld OK alex@alex-linux:~/workspace/HelloWorld/Release$ So far, so good. Now I copy the whole project tree to FreeBSD and trying to build it: $ cd /home/alex/project $ ls main.cpp release $ cd release $ ls makefile objects.mk sources.mk subdir.mk $ make "makefile", line 5: Need an operator "makefile", line 10: Need an operator "makefile", line 11: Need an operator "makefile", line 12: Need an operator CDT-generated makefile doesn't work. This is makefile beginning: $ Automatically-generated file. Do not edit! -include ../makefile.init RM := rm -rf $ All of the sources participating in the build are defined here -include sources.mk -include subdir.mk -include objects.mk ... Line 5 is -include ../makefile.init. Really, there is no such file. But it works by some way on Ubuntu computer. What is the trick, how can I build this? BTW, manually written makefile works: all: g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o"main.o" "../main.cpp" g++ -o"HelloWorld" ./main.o Note: $ in makefile is actually #, I replaced it because # creates formatting problems inside of stackoverflow pre block.

  • Reading excel files with xlrd

  • c# find nearest match to array of doubles

    - by Scott
    Given the code below, how do I compare a List of objects's values with a test value? I'm building a geolocation application. I'll be passing in longitude and latitude and would like to have the service answer back with the location closest to those values. I started down the path of converting to a string, and formatting the values down to two decimal places, but that seemed a bit too ghetto, and I'm looking for a more elegant solution. Any help would be great. Thanks, Scott public class Location : IEnumerable { public string label { get; set; } public double lat { get; set; } public double lon { get; set; } //Implement IEnumerable public IEnumerator GetEnumerator() { return (IEnumerator)this; } } [HandleError] public class HomeController : Controller { private List<Location> myList = new List<Location> { new Location { label="Atlanta Midtown", lon=33.657674, lat=-84.423130}, new Location { label="Atlanta Airport", lon=33.794151, lat=-84.387228}, new Location { label="Stamford, CT", lon=41.053758, lat=-73.530979}, ... } public static int Main(String[] args) { string inLat = "-80.987654"; double dblInLat = double.Parse(inLat); // here's where I would like to find the closest location to the inLat // once I figure out this, I'll implement the Longitude, and I'll be set }

  • Display weekday in textbox or label using date from textbox

    - by Niels Schultz
    I have a textbox with calendar extender and a label <label for="<%= tbxFrom.ClientID %>"> From</label> <asp:Label ID="lblWeekDayFrom" runat="server"></asp:Label> <asp:TextBox ID="tbxFrom" runat="server" CssClass="Calendar"></asp:TextBox> <cc1:CalendarExtender ID="extTbxFrom" runat="server" TargetControlID="tbxStartTag"> </cc1:CalendarExtender> and now I would like to show the weekday of the currently selected date, either using a formatting inside the textbox like Th 05/20/2010 or showing the weekday as string using the label on the left side of the texbox (lblWeekDayFrom). There is a calendarExtender to select the date, but I would also like to be able to have the users enter the date manually. I tried to use JQuery to capture changes, but the label is not showing anything, and it triggers the RequiredFieldValidator on every initial page load. $(document).ready(function() { $('#<%= tbxFrom.ClientID %>').change(updateDate($('#<%= tbxFrom.ClientID %>').val())) } ); function updateDate(date) { $('#<%= lblWeekDayFrom.ClientID %>').val(date); }

  • How to insert a blank line above my copyright text inside the comment lines in intelliJ IDEA?

    - by tim_wonil
    I'm using intelliJ IDEA 9. It has a function to make a copyright profile and apply to all files I create. What I'm trying to do is to format the copyright comment right. Suppose I have a copyright text as this: Copyright (c) 2010 my.company. All rights reserved. I wish it to be inserted in files automatically as following: //////////////////////////////////////////////////////////////////////////////// // // Copyright (c) 2010 my.company. All rights reserved. // //////////////////////////////////////////////////////////////////////////////// But when I enter the line "Copyright (c) 2010 my.company. All rights reserved." in the copyright profile (without quotes) and configure the formatting to use line comment and borders, and so on, I can only make it to display as below: //////////////////////////////////////////////////////////////////////////////// // Copyright (c) 2010 my.company. All rights reserved. //////////////////////////////////////////////////////////////////////////////// Even when I put the copyright text with blank line above and below to the template, as following, it still comes out like above. Copyright (c) 2010 my.company. All rights reserved. It seems to ignore blank lines in the copyright template. Is there any way to configure it so the copyright text will have blank lines above and below within the comments?

  • Flex AdvancedDataGrid - ColumnOrder With Formatter and ItemRenderer Question For Experts

    - by robin1126
    I have a advanceddatagrid that has around 15 columns. Some are string, some are numbers. I have shown 4 columns below. The number columns have formatting done for zero precision and 2 digits precision. The itemRenderer is just to show Blue Color if the number is +ve and Red Color if the number is -ve. It looks something like below ... I am trying to save the users setting of column order when he closes the application and reload with the same order when the user opens the applications. I am using SharedObjects and below is the code. for(var i:int=0; i< adgrid.columns.length;i++){ var columnObject:Object = new Object(); columnObject.columnDataField = adgrid.columns[i].dataField as String; columnObject.columnHeader =adgrid.columns[i].headerText as String; columnObject.width = adgrid.columns[i].width; columnArray.push(columnObject); } and then I save the columnArray to SharedObject. I retrive them using the below code for(var i:int=0;i adgrid.columns[i].dataField =columnArray[i].columnDataField; adgrid.columns[i].headerText =columnArray[i].columnHeader; adgrid.columns[i].width = columnArray[i].width; } How can I save and reload the Formatter and ItemRenderer data . I am having trouble saving the formatter and itemrenderer and reloading it again. I would really appreciate if you can shown the code. How can I reshuffle the columns but can preserve all the properties of it to the sharedobject and recover it again.

  • Property being immediately reset by ApplicationSetting Property Binding

    - by Slider345
    I have a .net 2.0 windows application written in c#, which currently uses several project settings to store user configurations. The forms in the application are made up of lots of user controls, each of which have properties that need to be set to these project settings. Right now these settings are manually assigned to the user control properties. I was hoping to simplify the code by replacing the manual implementation with ApplicationSettings Property Bindings. However, my first property is not behaving properly at all. The setting is an integer, used to record a port number typed into a text box. The setting is bound to an integer property on a user control, and that property sets the Text property on a TextBox control. When I type a new value into the textbox at runtime, as soon as the textbox loses focus, it is immediately replaced by the original value. A breakpoint on the property shows that it is immediately setting the property to the setting from the properties collection after I set it. Can anyone see what I'm doing wrong? Here's some code: The setting: [global::System.Configuration.UserScopedSettingAttribute()] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Configuration.DefaultSettingValueAttribute("1000")] public int Port { get{ return ((int)(this["Port"])); } set{ this["Port"] = value; } } The binding: this.ctrlNetworkConfig.DataBindings.Add(new System.Windows.Forms.Binding("PortNumber", global::TestProject.Properties.Settings.Default, "Port", true, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged)); this.ctrlNetworkConfig.PortNumber = global::TestProject.Properties.Settings.Default.Port; And lastly, the property on the user control: public int PortNumber { get{ int port; if(int.TryParse(this.txtPortNumber.Text, out port)) return port; else return 0; } set{ txtPortNumber.Text = value.ToString(); } } Any thoughts? Thanks in advance for your help. EDIT: Sorry about the formatting, trying to correct.

  • Why is Dispatcher.Invoke not triggering UI update?

    - by Brandon
    I am trying to reuse a UserControl and also borrow some logic that keeps track of progress. I'll try and simplify things. MyWindow.xaml includes a MyUserControl. MyUserControl has its own progress indicator (Formatting in progress..., Copying files..., etc.) and I'd like to mirror this progress somewhere in the MyWindow form. But, the user control has some logic I don't quite understand. I've read and read but I still don't understand the Dispatcher. Here's a summary of the logic in the user control that updates the progress. this.Dispatcher.Invoke(DispatcherPriority.Input, (Action)(() => { DAProgressIndicator = InfiniteProgress.AddNewInstanceToControl(StatusGrid, new SolidColorBrush(new Color() { A = 170, R = 128, G = 128, B = 128 }), string.Empty); DAProgressIndicator.Message = MediaCardAdminRes.ActivatingCard; ActivateInProgress = true; })); I thought I'd be smart and add an event to MyUserControl that would be called in the ActivateInProgress property set logic. public bool ActivateInProgress { get { return _activateInProgress; } set { _activateInProgress = value; if (ActivateInProgressHandler != null) { ActivateInProgressHandler(value); } } } I'm setting the ActivateInProgressHandler within the MyWindow constructor to the following method that sets the view model property that is used for the window's own progress indicator. private void SetActivation(bool activateInProgress) { viewModel.ActivationInProgress = activateInProgress; } However, the window's progress indicator never changes. So, I'm convinced that the Dispatcher.Invoke is doing something that I don't understand. If I put a message box inside the SetActivation method, the thread blocks and the window's progress indicator is updated. I understand basic threads but this whole Dispatcher thing is new to me. What am I missing?

  • Possible to use multiple ServiceReference.ClientConfig files?

    - by Maciek
    I'm building a modular Silverlight application, using Prism. In the Shell project, I'm loading 2x modules, each hailing from a separate assembly. For convenience let's call them ModuleA and ModuleB ModuleA makes calls to WebServiceA. A ServiceReference.ClientConfig file is present in ModuleA's assembly. In order for this to work, in the shell project, I've added an "existing item" (path set to the forementioned config file in ModuleA's folder) as a link. The shell launched and the ModuleA made a successful call to the WebServiceA. Currently, I'm working on ModuleB, it also needs to make webservice calls, this time to WebServiceB. The service reference has been added, and a ServiceReference.ClientConfig file has appeared in ModuleB's assembly. I've attempted to add that config file as a link to the shell project as well, but I've failed. Q1 : Is it possible to use multiple ServiceReference.ClientConfig files like this? Q2 : Are there any best-practices for this case? Q3 : Is it possible to rename a *.config or *.ClientConfig file ? How is it done? How do I tell the application what file to use? Edit : Formatting

  • What is the recommended coding style for PowerShell?

    - by stej
    Is there any recommended coding style how to write PowerShell scripts? It's not about how to structure the code (how many functions, if to use module, ...). It's about 'how to write the code so that it is readable'. In programming languages there are some recommended coding styles (what to indent, how to indent - spaces/tabs, where to make new line, where to put braces,...), but I haven't seen any suggestion for PowerShell. What I'm interested particularly in: How to write parameters function New-XYZItem ( [string] $ItemName , [scriptblock] $definition ) { ... (I see that it's more like 'V1' syntax) or function New-PSClass { param([string] $ClassName ,[scriptblock] $definition )... or (why to add empty attribute?) function New-PSClass { param([Parameter()][string] $ClassName ,[Parameter()][scriptblock] $definition )... or (other formatting I saw maybe in Jaykul's code) function New-PSClass { param( [Parameter()] [string] $ClassName , [Parameter()] [scriptblock] $definition )... or ..? How to write complex pipeline Get-SomeData -param1 abc -param2 xyz | % { $temp1 = $_ 1..100 | % { Process-somehow $temp1 $_ } } | % { Process-Again $_ } | Sort-Object -desc or (name of cmdlet on new line) Get-SomeData -param1 abc -param2 xyz | % { $temp1 = $_ 1..100 | % { Process-somehow $temp1 $_ } } | % { Process-Again $_ } | Sort-Object -desc | and what if there are -begin -process -end params? how to make it the most readable? Get-SomeData -param1 abc -param2 xyz | % -begin { init } -process { Process-somehow2 ... } -end { Process-somehow3 ... } | % -begin { } .... or Get-SomeData -param1 abc -param2 xyz | % ` -begin { init } ` -process { Process-somehow2 ... } ` -end { Process-somehow3 ... } | % -begin { } .... the indentitation is important here and what element is put on new line as well. I have covered only questions that come on my mind very frequently. There are some others, but I'd like to keep this SO question 'short'. Any other suggestions are welcome.

  • SQLCMD.EXE generates ugly report. How to format it?

    - by Juri Bogdanov
    I did batch to run SQL query like use [AxDWH_Central_Reporting] GO EXEC sp_spaceused @updateusage = N'TRUE' GO It displays 2 tables and generates some ugly report with some kind of 'P' unneeded letters... See below Changed database context to 'AxDWH_Central_Reporting'. database_name Pdatabase_size Punallocated space --------------------------------------------------------------------------------------------------------------------------------P------------------P------------------ AxDWH_Central_Reporting P10485.69 MB P7436.85 MB reserved Pdata Pindex_size Punused ------------------P------------------P------------------P------------------ 3121176 KB P3111728 KB P7744 KB P1704 KB ---------------------------------------------------------------- I also tryed to generate 1 table from this procedure with next query declare @dbname sysname, @dbsize bigint, @logsize bigint, @reservedpages bigint select @reservedpages = sum(a.total_pages) from sys.partitions p join sys.allocation_units a on p.partition_id = a.container_id left join sys.internal_tables it on p.object_id = it.object_id select @dbsize = sum(convert(bigint,case when status & 64 = 0 then size else 0 end)), @logsize = sum(convert(bigint,case when status & 64 <> 0 then size else 0 end)) from dbo.sysfiles select 'database name' = db_name(), 'database size' = ltrim(str((convert (dec (15,2),@dbsize) + convert (dec (15,2),@logsize)) * 8192 / 1048576,15,2) + ' MB'), 'unallocated space' = ltrim(str((case when @dbsize >= @reservedpages then (convert (dec (15,2),@dbsize) - convert (dec (15,2),@reservedpages)) * 8192 / 1048576 else 0 end),15,2) + ' MB') But got similar ugly report: database name Pdatabase size Punallocated space --------------------------------------------------------------------------------------------------------------------------------P------------------P------------------ master P5.75 MB P1.52 MB (1 rows affected) Is it possible to change the layout formatting for report?

  • Trouble getting NSString from NSDictionary key into UILabel

    - by Brian
    I'm attempting to put the value associated with the key called "duration" into a UILabel but I'm getting a blank or "(null)" result showing up in the UILabel. My NSDictionary object with its keys seems to be logging as being full of the data and keys I think I want, as such: the content of thisRecordingsStats is { "12:48:25 AM, April 25" = { FILEPATH = "/Users/brian/Library/Application Support/iPhone Simulator/3.1.3/Applications/97256A91-FC47-4353-AD01-15CD494060DD/Documents/12:48:25 AM, April 25.aif"; duration = "00:04"; applesCountString = 0; ...and so on. Here's the code where I'm trying to put the NSString into the UILabel: cell.durationLabel.text = [NSString stringWithFormat:@"%@",[thisRecordingsStats objectForKey:@"duration"]]; I've also tried these other permutations: cell.durationLabel.text = [thisRecordingsStats objectForKey:@"duration"]; and I've also tried this tag-based approach: label = (UILabel *)[cell viewWithTag:8]; label.text = [[thisRecordingsStats objectForKey:@"duration"] objectAtIndex:1]; and: UILabel *label; label = (UILabel *)[cell viewWithTag:8]; label.text = [NSString stringWithFormat:@"%@",[[thisRecordingsStats objectForKey:@"duration"] objectAtIndex:1]]; I've also tried creating a string from the key's paired value and see a "(null)" value or blankness using that too. What am I missing? I assume it's something with the formatting of the string. Thanks for looking!!

  • Parse a xml attribute depending on child content

    - by eddiefernberg
    Hello! I load an external xml file containing user metas looking like this: <?xml version="1.0" encoding="utf-8"?> <user_information> <user url="http://usersweb.com"> <name>Arnold</name> <lastname> <name>Arnoldson</name> </lastname> <age>42</age> </user> <user url="http://anotheruserweb.com"> <name>Arnold</name> <lastname> <name>Arichson</name> </lastname> <age>42</age> </user> And so on.... </user_information> I know the formatting with <lastname> is really stupid, but i can't modify the source. I want to load in the "url"-attribute from <user> , but only if <name> and <lastname> matches the name values i have stored in my own user database. I know how to parse the rest of it with PHP, but just the matching sequence seems difficult to me. Any help appreciated!
