  • Replacing old server with new but different hostname & same IP

    - by MaxFr
    We have an old server 2000 and lots of users point to it by hostname and by its IP e.g \\server1, we have a new server 2008 R2 with new name serverlocation1 All folders and data have been sync'toy'd from the old server1 across to serverlocation1 each evening, the new server tree is exactly the same on the new server and all perms are correct. We need to make the new server the same IP as the old server1 as too many people access it directly via IP, and to ensure file and folder paths stay ok, anything \\server1\folder\file needs to go to \\newserverlocation1\folder\file etc I can change the old server1 name to server1-old & change IP and assign the old IP to the new server, but how do I force anything coming in for \\server1 to go to the new server and ensure anything referenced to the old server goes onto the new server ? I can CNAME but I need the new server to have the IP of the previous server so not sure if its straight forward etc..... point server1 to newserverlocation1 Then probably change DNS so that the OLD IP points to new hostname..... Any clarification appreciated.

  • Popular .NET Compact Framework open source applications / components

    - by ollifant
    In my company I am responsible for the development of a .NET CF application which runs on top of Windows CE. We have invested much time in the development of a GUI framework, a top-level design which handles authorizations and navigation on the device, a IoC customer, ... Now I was wondering if there are any other projects which show kind of best practices (for example what the prefered way of GUI drawing is). In the following there are some which I know: UI Framework for .NET Compact Framework 3.5 Project Resistance Amplite Application Port from IPhone* Several twitter clients CaveMen from LightWorkGames* What applications / components do you know? * actually not a application, but definetely worth to take a look

  • Remote I/O costs with a Content Delivery Network

    - by x711Li
    As far as I know, the time complexity of scanning a directory and the amount of files in said directory are correlated due to I/O costs. Would the administrative costs of placing the files in a hashed directory tree for uploading/downloading files through a CDN API be worth it for the added efficiency? For instance, given a filename foo.mp3, the MD5 hash for this is 10ebb1120767e9de166e0f5905077cb1. Thus, storing foo.mp3 in ./10/eb/foo.mp3 would allow for less files per directory (assuming MD5 generates patterns with in Base36, this allows for 36^2 root directories with 36^2 subdirectories each and little chance of hash collision) Considering the directories themselves are not loaded, would the I/O costs of directory scanning still exist with direct uploading/downloading?

  • How can I filter images and use filesystemview icons in my jtree?

    - by HoLeX
    First of all sorry about my english. So, i have some problems with my JTree because i want to filter specific types of images and also i want to use icons of FileSystemView class. Can you help me? I will appreciate so much.

  • Storing Object Types in Variable then Initializing

    - by Jon Mattingly
    Is there a way in Objective-C to store an object/class in a variable to be passed to alloc/init somewhere else? For example: UIViewController = foo foo *bar = [[foo alloc] init] I'm trying to create a system to dynamically create navigation buttons in a separate class based on the current view controller. I can pass 'self' to the method, but the variable that results does not allow me to alloc/init. I could always import the .h file directly, but ideally I would like to make reusing the code as simple as possible. Maybe I'm going about this the wrong way?

  • Should I use interface builder or not?

    - by Michael Waterfall
    I'd like to know more about the pros and cons of using interface builder when developing iPhone/iPad apps. I've written a fairly complex and customized app that's on the app store right now, but all of the interfaces are hand coded as they are fairly complex. I've customised the navigation and tab bars with backgrounds, table view cells are manually drawn for speed, and some views are complex and scalable with many subviews. I'm pondering whether or not to start using interface builder but I'm not sure to what extent I'll use it and whether it's worth it at all. Is it quicker? Can things still be easily customised? Any advice would be most welcome!

  • checkbox selected value is lost after coming back to the pagei.e., viewstate value is lost with use

    - by M.Vijay bhasker
    In the left navigation i have a series of check boxes and a grid view in the page body.Grid view results changes based on the check box selection,whenever i click on the links in grid view it goes to the second page and there is a link on the page which takes me back to the first page,but the check box selected value is maintained for the first time only and if we repeat the same process for the second time and i see that the first time selection of the check box is maintained.Here the grid view is placed in update panel and the check box in the left is called using .... AsyncPostBackTrigger ControlID="cphLeftNavigation". I've tried removing the above code referring the cphLeftNavigation and i see the results are coming up correctly and the last selected check box value is being maintained correctly and i want the same functionality to be implemented with/without update panel. Can anyone let me know,what exactly should i change to implement the above mentioned functionality.

  • How to set UITableView to Grouped?

    - by 4thSpace
    In an iPhone navigation based app, I want to add a second tableview but have its design available in IB. I've added a new empty XIB and dragged a UITableView onto it. I want to setup the layout through IB. I've created a controller for this tableview and set the File's Owner class in IB to this controller. I linked the tableview to File's Owner as well. I set the tableview to grouped in IB. However, that does not translate at runtime. I still have a plain tableview. In fact, none of the Inspector settings work at runtime. What have I missed?

  • IIS FTP server not working after purchase of SSL certificate

    - by Chris
    I've been connecting to my web server with active mode in FileZilla with no problems. Over the weekend, an SSL certificate was dropped into a folder that I access with FTP, and which contains files for the website. Now I am receiving a 425 error in active mode on the FTP root, so I can't really do anything but log in. In passive mode, I can connect and move around in the directory tree, but the connection seems shaky. Occasionally I'll time out, and I can't get access at all to the folder containing the SSL certificate. My question is how does the SSL certificate affect my FTP connection (if at all)? Does its presence demand the use of FTP over SSL? Note: As far as I know, the only change which occurred was the placement of the SSL certificate. Firewall settings, FTP client and server settings should all be the same as before, when everything was working.

  • How to let Linux Python application handle termination on user logout correctly?

    - by tuxpoldo
    I have written a Linux GUI application in Python that needs to do some cleanup tasks before being terminated when the user logs out. Unfortunately it seems, that on logout, all applications are killed. I tried both to handle POSIX signals and DBUS notifications, but nothing worked. Any idea what I could have made wrong? On application startup I register some termination handlers: # create graceful shutdown mechanisms signal.signal(signal.SIGTERM, self.on_signal_term) self.bus = dbus.SessionBus() self.bus.call_on_disconnection(self.on_session_disconnect) When the user logs out, neither self.on_signal_term nor self.on_session_disconnect are called. The problem occurs in several scenarios: Ubuntu 14.04 with Unity, Debian Wheezy with Gnome. Full code: https://github.com/tuxpoldo/btsync-deb/tree/master/btsync-gui

  • Navigating by foreign keys in ADO.NET Entity Framework/MySQL

    - by Werg38
    I am using ASP.NET MVC2 on top of a MySQL database in VS2008. I am using the MySQL ADO.NET connector 6.2.3 to provide the connection for the ADO.NET Entity Data Model. This is mostly working ok, however navigating via foreign keys is causing me a real headache! Here is a simplified example.. Car (Table) CarID PK Colour Doors ManufacturerID FK Manufacturer (Table) ManufacturerID PK Name In the edmx file I can see the 1-many relationship shown as a navigation property in the both the Car and Manufacturer tables. I create a Models.CarRepository that allows me to returns a IQueryable. At the View I want to be able to display the Manufacturer.Name for each car. This is not accessible via the object I get returned. What is best way to implement this? Have I encountered a limitation of the Entity Framework/MySQL combination?

  • git log throws error "ambiguous argument"

    - by LonelyPixel
    This used to work about a year ago. Now it doesn't: git log --abbrev=6 The expected result would be all commit hashes abbreviated to 6 characters. The actual result is now this error message: fatal: ambiguous argument '6': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git [...] -- [...]' I have the impression that Git doesn't even know about that argument and tries to silently ignore its name but not the value. Using Git 1.8.1.msysgit.1 on Windows 7. Addition: Oh and it fails on other parameters, too. The entire command is: git log --abbrev=6 --format=format:"----- Commit %%h on %%ci by %%an -----%%n%%n%%B" If I just leave the abbrev part out, it still returns another error: fatal: Invalid object name 'format'.

  • Nginx PHP-FPM Basic Auth

    - by Lari13
    I have nginx with php-fpm installed on Debian Squeeze. Directory tree is: /var/www/mysite index.php secret_folder_1 admin.php static.html secret_folder_2 admin.php static.html pictures img01.jpg I need to close secret_folder_1 and secret_folder_2 with basic_auth. Now config looks like: location ~ /secret_folder_1/.+\.php$ { root /var/www/mysite/; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME /var/www/mysite$fastcgi_script_name; include fastcgi_params; auth_basic "Restricted Access"; auth_basic_user_file /path/to/.passwd; } location ~ /secret_folder_1/.* { root /var/www/mysite/; auth_basic "Restricted Access"; auth_basic_user_file /path/to/.passwd; } Same config for secret_folder_2. Is it normal? I mean, first location for serving php files in restricted folder, and second location for serving static files. Can it be simplified?

  • tableView resize problem when pushing another view while keyboard is showing

    - by Rollin_s
    I have a tableview controller under a navigation controller. Some of my table cells contain text fields, so when I tap on them, a keyboard will show up and automatically resize (shrink) the bounds of my tableview. The bounds is then restored when the keyboard is dismissed programmatically by calling resignFirstResponder on my text field. Some of my cells would push a new view controller into the view stack when tapped on, so I first resign my current textfield before pushing the view controller: - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (currentEditingTextField != nil) { [currentEditingTextField resignFirstResponder]; currentEditingTextField = nil; } return indexPath; } The problem is when I navigate back to my table view, the bounds of the tableview is sized as if the keyboard is still there. I know this because the scroll indicator only reaches right above where the keyboard was and there is empty view space below the table view. Anybody experienced this and know of a solution? Thanks

  • I had inserted a jQuery tab in my site. It was working fine till sometime ago. Suddenly it stopped w

    - by vr3690
    Hello, I had inserted two jQuery tabs on my site. One div container had the id - tabs and another had the id tabs-for-views. Both of them were working fine till sometime ago, until i made some changes. I don't remember what the exact changes were.. Right now, the first tab uses the jQuery UI theme I am using. As in, I can see the tab navigation and content panels - but on clicking the tabs nothing happens. But the second (tabs-for-views) is not even converted to proper tabs format. I am using the Drupal CMS for this site. the tabs can be found on this page: http://betterclassofleaders.co.cc/whackk/ this is the jquery ui css file i am using: (insert first link)sites/default/themes/whack_custom/jquery-ui-1.7.2.custom.css

  • Zend Database Adapter - Complex MySQL Query

    - by Sonny
    I have defined a function in my Navigation model that executes a query, and I was wondering if there's a more "Zendy" way of generating/executing the query. The query I'm using was proposed by Bill Karwin on another thread here for setting arbitrary record order. I tried using a prepared statement, but the values in the SIGN() function got quoted. I'm using the PDO adapter for MySQL. /** * */ public function setPosition($parentId, $oldPosition, $newPosition) { $parentId = intval($parentId); $oldPosition = intval($oldPosition); $newPosition = intval($newPosition); $this->getAdapter()->query(" UPDATE `navigation` SET `position` = CASE `position` WHEN $oldPosition THEN $newPosition ELSE `position` + SIGN($oldPosition - $newPosition) END WHERE `parent_id` = $parentId AND `position` BETWEEN LEAST($oldPosition, $newPosition) AND GREATEST($oldPosition, $newPosition) "); return $this; }

  • How can I find the names of AD Group policies that a user/pc is using?

    - by Russ
    I am having trouble locating some settings in group policy so I can make changes due to the convoluted nature of our policies. What I would like to be able to do is go to a specific PC and see what group policies are being applied, so I can focus on those policies. My goal would be to clean up the GP's a bit, while allowing me to "walk the tree" to see what people have implemented and what is worthless. Thanks. EDIT: In this specific case, I am looking to find which GP maped drives are configured in. (User Configuration -- Preferences -- Windows Settings -- Drive Maps)

  • How to find all photos taken in April - any April?

    - by Mawg
    I have 100+ gB of photos going back 25 years. They are arranged in a directory tree by category, with nested sub-directories. How can I make a search for all photos taken in a given month, say April, in any of those directories? I don't think that a Windows search will work as that will probably be the file creation data, which could be a month or two later wen I finally more the files from SD card to PC. Perhaps searching the EXIF data? Is there a free program which can do that?

  • How to reduce the lag time when using jquery to modify css onload

    - by Josh
    I have a jquery function that is called on $(document).ready that modifies the css of a Business Intelligence dashboard. I had to use jquery to make the adjustments because I do not have access to the source code of the BI tool. What happens is when the page loads, I run through the tab navigation and change the colors of the tabs based on certain requirements (which is basically dependent on the text of the tab). The issue I am facing is that there is a small lag time from when the page initially loads to when the jquery updates have been made to the page. Is there a way to reduce this lag time?

  • How to troubleshoot Application Popup issues 0XC0000142 and 0XC000009a

    - by DotDot
    I am running randomly into 1 of these popups when our application runs. The machines range from 8GB/8Core to 24GB/24Core and run Windows Server 2008 R2. The application is a bunch of perl scripts and exe's that are expected to utilitize the server well. The process tree can be quite deep (5-6 child levels) and quite broad (60-70 level 1 processes). We hit this issues every 1% run on random machines. The application stalls on popup, unless someone clicks the damn button. The event log reads as cmd.exe - "Failed to initialize app. Click OK to close app" How could I reliably repro these issues?

  • Users adding views

    I have created a main page (myAppViewController) and a add page rect button I have also created a page template (TemplateAViewController) all set up in Interface builder. I would like users to be able to add as many templates themselves and then page through them. I am not sure where to start. I can create views programmatic like so -(IBAction)createnewpage : (id) sender { myAppViewController *viewcontroller = [[myAppViewController alloc] initWithNibName:@"TemplateAViewController" bundle:[NSBundle mainBundle]]; [[self view] addSubview:viewcontroller.view]; } I then want to be able to navigate through these views- I guess I need to create a navigation controller to do this ?
