  • Recommendations for C# controls that can be used to create a hierarchical list of prioritised items?

    - by Mendokusai
    I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Anyone got any recommendations for controls for me to look at?

  • Retrieving Spotlight query used to open document in application

    - by vicvicvic
    If you search for something that opens Preview.app (e.g. a PDF file) in Spotlight, the application not only opens the file but actually copies the Spotlight query into the application's search field (for deeper search). iPhoto and Mail.app also do this. This is a really nice feature. Unfortunately, Apple does not document how it's implemented. Opening a document from Spotlight appears to simply send application:openFile to the application delegate. Is it possible to retrieve the user's Spotlight query somehow? Or is this a hardcoded feature of Spotlight?

  • Two users using the same same user profile while not in a domain.

    - by Scott Chamberlain
    I have a windows server 2003 acting as a terminal server, this computer is not a member of any domain. We demo our product on the server by creating a user account. The person logs in uses the demo for a few weeks and when they are done we delete the user account. However every time we do this it creates a new folder in C:\Documents and Settings\. I know with domains you can have many users point at one profile and make it read only so all changes are dumped afterwords, but is there a way to do that when the machine is not on a domain? I would really like it if I didn't have to remote in and clean up the folders every time.

  • Detecting a message box launched in another application

    - by richard-assaf
    I am developing a windows service, in vb .et, that launches a legacy application that performs some work. The service acts as a wrapper around the legacy app allowing users to automate an otherwise manual operation. Everything is working great, except occasionally the legacy app displays a messagebox. When it does this the process halts until the the message box closes. As the service will be running on a server there will be no user to close the message box. The service launches the legacy application in a System.Diagnostics.Process. My question is, is there way to detect that a message box has been displayed by a process that I have started using System.Diagnostics.Process and is there a way to through code to close the messagebox. I've tried to be brief so if you need more information please let me know. Thanks in advance Richie

  • What values does Camera.Parameters.set("picture-size", ?) take?

    - by mobilekid
    Hi, my app involves some work with the camera, therefore it needs to handle capturing of images with different resolution. My targets are 1.6 - onwards. Does anyone know what to pass in the value argument for Camera.Parameters.set("picture-size", value) I have look at the Donut release of the Camera app, however, it was not very clear what exactly has been used there as the value is retrieved from the SharedPreferences. // Set picture size parameter. String pictureSize = mPreferences.getString(CameraSettings.KEY_PICTURE_SIZE, getString(R.string.pref_camera_picturesize_default)); mParameters.set(PARM_PICTURE_SIZE, pictureSize); Lookin at the strings.xml I can see that R.string.pref_camera_picturesize_default = 2048x1536, however, I'm not sure what other values can be passed there? Is it any resolution you fancy, or are they only certain resolutions the drivers can handle? Thanks.

  • Getting exc_bad_access error only when mallocguard is enabled

    - by Nareshkumar
    I have an app for iPhone in development which works properly when the Malloc guard is not enabled. However when i try to enable the malloc guard i get the following error after the app is loaded. #0 0x95f65684 in objc_msgSend () #1 0x30506515 in NSPopAutoreleasePool () #2 0x30901697 in _UIApplicationHandleEvent () #3 0x32046375 in PurpleEventCallback () #4 0x30245560 in CFRunLoopRunSpecific () #5 0x30244628 in CFRunLoopRunInMode () #6 0x308f930d in -[UIApplication _run] () #7 0x309021ee in UIApplicationMain () Now my problem is that i am not able to debug the exact location where its getting the error.. have tried malloc_error_break but didnt work out. Is it that malloc guard enabling auto releases some of the objects based on allocation??

  • How to locally resume a session that has been started remotely using xrdp?

    - by Jaroslav Záruba
    Can I connect to a RD session that has been started (and abandoned) from a remote machine using xrdp? Also I'd like to be able to do the exact opposite: to remotely login to a session that has been initiated locally. I'm trying to get as close as possible to how Windows RS behaves. (Which also includes that the session would use my terminal machine/monitor resolution. I wasn't able to achieve that using VNC.) Suggestions to a better alternative to xrdp are welcome please. I don't know Linux too much.

  • NoClassDefFoundError with new eclipse bundle

    - by djmedic
    I am informed by a customer that they are receiving an error. On the report they filed it is continuosly coming up with NoClassDefFoundError. It appears none of my other customers are having this issue. I'm not having this issue running the app on my Motorola Droid Maxx. The customer is running the app on a rooted Droid Bionic. Everything was working fine on my version at 2.3 but when I updated it to 2.4, this issue arose. I also replaced my computer with a new and now I am running windows 8 and installed the adt bundle.

  • Locked out by changing file permissions

    - by Valeriy
    I just locked my root account (and all other accounts if it matters) completely out of the RHEL 5.4 by changing permissions on every file to 400. Now I have "Permission denied" on any command that I try to run, including chmod itself. Any idea on how to recover? The only access I have to the server is via terminal or SSH. (If anyone cares how it happened, I was running a hardening script and one of the lines was supposed to change permission on some config files in /etc directory. It has couple of variables that had not been set, so the command essentially evaluated to chmod -R 0400 /* Ouch! This is sure a great lesson on checking the scripts even more carefully in the future but what can I do now?

  • Three20 Library Cannot find its own headers Xcode iPhone

    - by DieLaughing
    import "Three20/Three20.h" Fails. Go download it and build a sample app. If that works, then make a new app from the templates provided, then watch as it fails spectacularly to find the right HEADER_SEARCH_PATH. 1) I've gone to the info page for the TARGET and not the PROJECT (Well, I tried both) and tried a bunch of different paths for the HEADER_SEARCH_PATH field. 2) I've tried dragging and dropping the dependent files from the finder and COPYING or just referencing both fails. (RANT: WTF?! Really? I wish public code libraries saved me time ONCE in my life.)

  • Showing/Hiding windows iPhone Dev

    - by Cal S
    In my iPhone app I am developing, I have defined two windows: @interface The_NoteAppDelegate : NSObject <UIApplicationDelegate> { IBOutlet UIWindow *newNoteWindow; IBOutlet UIWindow *homeWindow; } @property (nonatomic, retain) UIWindow *newNoteWindow; @property (nonatomic, retain) UIWindow *homeWindow; and they are linked correctly in IB - but how do I show/hide these windows? [homeWindow makeKeyAndVisible]; works in appDidFinishLaunching but when I try [newNoteWindow makeKeyAndVisible]; again to open the other window (on a button touch event) in front of the other, the app freezes. I know this is a very n00by question but please help me out :)

  • Dual Touchscreens in Different Rooms

    - by Ash
    I'm planning on having one dual-core system running two touchscreens, each in its own room in the house. I'd like to be able to use the internet on one, while someone else uses the other to record music - each of us interacting with the screen as we would separate computers. I was also thinking that running each screen, or certain programs, on its own core might make this work more smoothly. Will this setup work in Windows 7 Home on a mini-tower or do I need to invest in a server to get this sort of workstation/terminal setup to work?

  • Execute current UITextField autocorrect suggestion when another button is pressed

    - by Allara
    I am implementing chat in my application, very similar to the iPhone's built-in Messages app. I have a UITextField next to a button. The user types something into the text field, and very often the text field suggests various autocorrections. In the built-in Messages app, tapping the Send button will cause the currently visible autocorrection suggestion to execute. I am seeking this behavior in my application, but haven't been able to find anything. Does anyone know of a way to programmatically execute the currently visible autocorrection/autocomplete suggestion of a UITextField when a completely separate control is activated? It's obviously possible somehow.

  • Xterm is not completely erasing field lines

    - by user26367
    We have a SSH tunnel to a remote unix box from Windows clients using Cygwin. It launches a terminal program from the unix box locally on the Windows box for data input. The xterm window is launched as follows xterm -fn 10x20 -bg DodgerBlue4 -fg white -cr white -ls -geometry 90x30 -e program When a screen goes from read only mode to edit mode, the edit fields have ____. When going back to read only mode, a single pixel artifact is left behind for each field. *readonly* User: *edit* User: ___________ *after edit exit* User: . <- this dot is left behind Any idea what we need to change to fix this?

  • How to see what objects lie in which generation in YourKit?

    - by prams
    I am using YourKit (11.0) to try to profile my j2ee app. The app uses java 6 and running on 64-bit linux (centos). I was told that YourKit possibly tells us which objects exist in which generation (eden, old, etc) at any given point of time. On a side note, I am trying to chase a problem where memory usage keeps increasing until a major collection happens (every 4 hrs) and I am suspicious about few particular objects, so I am interested to know where those objects lie at different times. Fortunately I know lot of memory is being consumed in one particular area of code (so other objects are possibly directly being put into the old gen), but don't exactly know how much of that memory is being put into eden space, how much is being collected by the minor collections, etc. Thanks.

  • Ubuntu/Linux version recommendation for HP dv6 3122TX?

    - by sanjayav
    I purchased a HP dv6 3122TX recently and after installing Ubuntu 10.10 64 bit I ran into multiple issues like, The wireless driver is not supported by Uubntu. (1) [The driver is RaLink RT3090 ] The ethernet stopped working sometimes for no reason [The driver is Realtek RTL8111/8168B ] "Corrupted low memory at ..." issue which is described as a kernel bug in Ubuntu support forums. (It started to take me to a terminal instead of the GUI and couldn't start x server after that) As I'm not an expert Ubuntu user I got fed up of all these issue and got back to Windows 7. But I need an Ubuntu installation up and running for my development work. What are your suggestions about a reasonable Ubuntu version that I should try? Or a different Linux variation? Should I stick to a 32-bit version? It'd be great anyone can give some advice on this issue.

  • Can I autologin a specific user on a specific VT, but still have other login shells running?

    - by Michael
    I'm running a linux system with Ubuntu Karmic on it, and I use it to run a webcam and a program that continuously outputs on the console. Is there any way I can force a user to login on VT2, and then switch VTs to VT2, but still have other login consoles running so I can hook a keyboard up to it and CTRL-ALT-F# to get to another terminal? I have a feeling this needs to go in my rc.local file, but nothing in the login manpage seems to suggest it can do what I want it to do. If there is no way to login a user on the vt, launching the program directly on a specific VT will work as well, since the user's shell in /etc/passwd is set to the program anyway.

  • Perform Push Segue From a Tab View Controller

    - by user1416492
    I have a Tab Bar Controller App, the tab bar controller is forked into several "tab" view controller, in one of the view controller I want to redirect the user to an other view controller. I create a segue from that tab view controller to the destination view controller and given it an Identifer. And I call "performSegueWithIdentifier" in "viewDidAppear" to redirect the user. It works fine when the segue is "Modal", however since I want to retain the tabs, I want to call the segue through "Push". However, once I change the segue to "Push", it is not working anymore (it does not try to go to the destination view controller). The app did not crash on the simulator but just staying on the origin tab view controller.

  • Text on Cisco ASA console is garbled/missing letters

    - by Some Linux Nerd
    I've actually looked up a number of solutions for this problem and none of them work. There's this Cisco ASA 5505 that I'd like to use, that outputs mildly garbled text with missing characters. I did some googling and found that the most likely problem is a bad baud rate, so I tried all the baud rates, 7N1, 8N2... basically every possibility minicom had. Then I figured (since I can type ok, just not read) that if I factory reset it that it would fix whatever is set wrong with the terminal. That didn't work either. This usb-db9 adapter and console cable work fine on the catalyst switch in our office. My serial settings are 9600 8N1 with no flow control. Anyone know how to fix this? I have an example of the text on pastebin: http://pastebin.com/MAJF0mVU - it's just lots of "Dfaut cnfiuraionfil cotais 1enty." instead of "Default configuration blah blah"

  • How can a C/C++ program put itself into background?

    - by Larry Gritz
    What's the best way for a running C or C++ program that's been launched from the command line to put itself into the background, equivalent to if the user had launched from the unix shell with '&' at the end of the command? (But the user didn't.) It's a GUI app and doesn't need any shell I/O, so there's no reason to tie up the shell after launch. But I want a shell command launch to be auto-backgrounded without the '&' (or on Windows). Ideally, I want a solution that would work on any of Linux, OS X, and Windows. (Or separate solutions that I can select with #ifdef.) It's ok to assume that this should be done right at the beginning of execution, as opposed to somewhere in the middle. One solution is to have the main program be a script that launches the real binary, carefully putting it into the background. But it seems unsatisfying to need these coupled shell/binary pairs. Another solution is to immediately launch another executed version (with 'system' or CreateProcess), with the same command line arguments, but putting the child in the background and then having the parent exit. But this seems clunky compared to the process putting itself into background. Edited after a few answers: Yes, a fork() (or system(), or CreateProcess on Windows) is one way to sort of do this, that I hinted at in my original question. But all of these solutions make a SECOND process that is backgrounded, and then terminate the original process. I was wondering if there was a way to put the EXISTING process into the background. One difference is that if the app was launched from a script that recorded its process id (perhaps for later killing or other purpose), the newly forked or created process will have a different id and so will not be controllable by any launching script, if you see what I'm getting at. Edit #2: fork() isn't a good solution for OS X, where the man page for 'fork' says that it's unsafe if certain frameworks or libraries are being used. I tried it, and my app complains loudly at runtime: "The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec()." I was intrigued by daemon(), but when I tried it on OS X, it gave the same error message, so I assume that it's just a fancy wrapper for fork() and has the same restrictions. Excuse the OS X centrism, it just happens to be the system in front of me at the moment. But I am indeed looking for a solution to all three platforms.
