  • Option to save project files for later use in Dreamweaver?

    - by Lup T. Ma
    Does anyone know of an extension or other way to allow me to save a set of files in a project for later use? Example: - Working on site A, opened html files A1-A15 (15 files) Received a request to work on site B, new files (number unimportant). I would like DW to remember that I was working on files A1-A15. Close the site A files and focus on just files from site B. Complete site B work. Reopen site A files altogether. Suggestions are greatly appreciated. Thanks!

  • Stairway to Database Design - STEP 1: Data Elements

    Before you start to think about your database schema or tables, you need to consider your data: The type of data it is, the scale you use for values. It needs to be unique, precise and unambiguous. Then you need to name it in such a way that it can be generally understood. Joe Celko explains...

  • Excel techniques for perfmon csv log file analysis

    - by Aszurom
    I have perfmon running against several servers, where I'm outputting to a .csv file data like CPU %time, memory bytes free, hard disk I/O metrics like s/write and writes/s. The ones graphing the SQL servers are also collecting SQL stats. The web servers are collecting .Net relevant stuff. I am aware of PAL, and used it as a template of what data to capture based on server type actually. I just don't think the output it generates is detailed or flexible enough - but it does a pretty remarkable job of parsing logs and making graphs. I'm borderline incompetent with Excel, so I'm hoping to be directed to some knowledge of how to take a perfmon output .csv and mine it in Excel to produce some numbers that are meaningful to me as a sysadmin. I could of course just pick a range of data and assemble a graph out of that and look for spikes and trends, but I'm convinced there is some technique to this that makes it more manageable than looking at a monsterous spreadsheet of numbers and trying to make graphs of it. Plus, it's pretty time consuming and not something I can do as a "take a glance at the servers" sort of routine. I'm graphing CPU, disk use, network b/sec, etc. in Cacti as well, which is nice for seeing big trends. The problem is that it is 5 minute averages, so a server could have a problem but it's intermittent and washes out in a 5 min average. What do you do with perfmon data that I could learn from?

  • MySQL tmpdir on /dev/shm with SELinux

    - by smorfnip
    On RHEL5, I have a small MySQL database that has to write temp files. To speed up this process, I would like to move the temporary directory to /dev/shm by putting the following line into my.cnf: tmpdir=/dev/shm/mysqltmp I can create /dev/shm/mysqltmp just fine and do chown mysql:mysql /dev/shm/mysqltmp chcon --reference /tmp/ /dev/shm/mysqltmp I've tried to make SELinux happy by applying the same settings that are in effect for /tmp/ (and /var/tmp/), which is presumably where MySQL is writing its tmp files if tmpdir is undefined. The problem is that SELinux complains about MySQL having access to that directory. I get the following in /var/log/messages: SELinux is preventing mysqld (mysqld_t) "getattr" to /dev/shm (tmpfs_t). SELinux is a hard mistress. Details: Source Context root:system_r:mysqld_t Target Context system_u:object_r:tmpfs_t Target Objects /dev/shm [ dir ] Source mysqld Source Path /usr/libexec/mysqld Port <Unknown> Host db.example.com Source RPM Packages mysql-server-5.0.77-3.el5 Target RPM Packages Policy RPM selinux-policy-2.4.6-255.el5_4.1 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name catchall_file Host Name db.example.com Platform Linux db.example.com 2.6.18-164.2.1.el5 #1 SMP Mon Sep 21 04:37:42 EDT 2009 x86_64 x86_64 Alert Count 46 First Seen Wed Nov 4 14:23:48 2009 Last Seen Thu Nov 5 09:46:00 2009 Local ID e746d880-18f6-43c1-b522-a8c0508a1775 ls -lZ /dev/shm shows drwxrwxr-x mysql mysql system_u:object_r:tmp_t mysqltmp and permissions for /dev/shm itself are drwxrwxrwt root root system_u:object_r:tmpfs_t shm I've also tried chcon -R -t mysqld_t /dev/shm/mysqltmp and setting the group on /dev/shm to mysql with no better results. Shouldn't it be enough to tell SELinux, hey, this is a temp directory just like MySQL was using before? Short of turning off SELinux, how do I make this work? Do I need to edit SELinux policy files?

  • Can an image based backup potentially corrupt data?

    - by ServerAdminGuy45
    I'm considering doing image based backups (Acronis) on production Windows systems during non-peak hours. I'm just wondering if they can potentially lead to application data corruption. Lets say that I have a database that is getting hit pretty hard. Could I potentially have the beginning blocks of the database be commit ed to the image, data inserted into the db (which changes the beginning blocks of the DB on the server but not the image), then the blocks of data committed to the image (leading to an inconsistent state). Here's an example of what I'm trying to illustrate. Imagine a simple data structure which has a number in the front which represents the number of "a"s in a file. The number and data are delimited by a "-". For example: 4-ajjjjjjjajuuuuuuuaoffffa If an "a" is changed, the datastructure resets the number in the begining of the file such as: 3-ajjjjjjjajuuuuuuuboffffa I assume acronis writes block by block being a straight up image so here is what i'm invisioning happening with my database t0: 4-ajjjjjjjajuuuuuuuaoffffa ^pointer is here t1: 4-ajjjjjjjajuuuuuuuaoffffa ^pointer is here (all data before this is comitted to the image) t2: 4-ajjjjjjjajuuuuuuuboffffa ^pointer is here (all data before this is comitted to the image) Also notice how one of the "a"s change to a b. There are only 3 "a"s now t3: 4-ajjjjjjjajuuuuuuuboffffa ^pointer is here (all data before this is comitted to the image) The final image now reads "4-ajjjjjjjajuuuuuuuboffffa", while the true data is "3-ajjjjjjjajuuuuuuuboffffa" leading to a corrupt "database". Basically changes further down the blockchain could be reflected in the image, while important header and synchronization could already be committed. The out of date header information doesn't accurately reflect the structure of the blocks to come.

  • Is it possible to re-cab an Administrative Install Point?

    - by Nathaniel Bannister
    We have Acrobat 8 Pro at work, and our media was painfully out of date. Rather than install all of the machines at 8.0.0 and then do the 6 or 7 consecutive reboots adobe expects you to be ok with I decided I'd integrate the .msp files into the installer. After reading up on it, I figured out the exact patch order that adobe required, extracted my cd to an Administrative install point, and ran the patches against it: msiexec /a AcroPro.msi /p AcrobatUpd810_efgj_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd811_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd812_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd813_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd816_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd817_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd820_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd822_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd823_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd825_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" msiexec /a AcroPro.msi /p AcrobatUpd826_all_incr.msp TARGETDIR="C:\Acrobat8" /log "output.log" Now I have a AIP that is fully patched to 8.2.6 (Tested working prior to attempting to CAB it), but is absolutely huge (1.2gb) what I would like to do is take the folders within the AIP and put them back into a cab file for the sake of convenience in transferring the files around. I tried the command: cscript "C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\sysmgmt\msi\scripts\WiMakCab.vbs" AcroPro.msi Data1 /L /C /S Per the guide I was using, while this did produce the cab file I Wanted, however the resulting MSI fails to install with an error 2602: It's been a while since I've done something like this, and it's probably a glaring oversight on my part, but any insight would be much appreciated.

  • Can't resolve offline file conflicts

    - by Bryan
    We use roaming profiles on our Server 2008 R2 domain, with folder redirection for 'desktop', 'my documents' and 'application data'. But as our network is split across two sites, we have one file server at each site, which are configured to use domain based DFS namespaces and DFS replication to keep things in sync. The DFS path for the replication folder is as follows: \\domain\folderredirection$\<username>\<redirected-folder-name> The real paths are \\site-1-server\folderredirection$\<username>\<redirected-folder-name> and \\site-2-server\folderredirection$\<username>\<redirected-folder-name> As our users all switch between sites (sometimes several time per day), our folder redirection policy has to redirect to the DFS roots rather than hardcoded to a specific server. Both DFS and DFS-R have been proven to be working perfectly. On our laptops, we use offline files for the redirected folders, and this also works fine, however the problem is as follows: When conflicts occur in offline files, it is impossible to resolve the conflicts. I'm given the usual conflict resolution options (i.e. 'Ignore', 'Keep Both', 'Keep network' and 'Keep local'), however, not one of these options will resolve any conflict, yet no error is produced. We only use offline files on laptops, which have either Windows XP Professional or Windows 7 Professional installed. The problem is not specific to any one laptop, it affects every laptop and every conflicting file in exactly the same way. I would have thought the set up we have is common for companies that have multiple sites, so I'm hoping someone will have seen this before?

  • Seeking web-based FTP client for very large file upload

    - by Paul M. Nguyen
    I have looked around for these for some time... the limits imposed by the web server and/or the dynamic programming environment (e.g. PHP) are far too restrictive for the application I'm working on. We need to be able to move large graphics and video files to and from clients (ranging from tens of MB to a few GB in a single file). Plain FTP with a proper desktop client will do the trick, and we're hosting this in Amazon EC2 with EBS. User management will be done from the office via webmin. Users are chroot-jailed into their home dir by proftpd. net2ftp will work for many clients, but we often need to move single files that approach 1GB or exceed 2-3GB which is way out of the range of any http-based uploader. So we turn to Java or Flash - can they do it? From within the web browser establish an FTP connection and grab a huge file? There are licensed applets and such out there, but none seem convincing. Again, I'm looking for some code that can speak FTP and read (& write?) the local disk, that is delivered in a web browser, and can move single files of 2GB+. The reason for having a web-based interface to FTP is to skip the software installation step for our clients. I will consider proper desktop client software as long as it's "portable" and at least Win+Mac and can be easily configured by lay-man users in a hurry.

  • Cannot get at data in my NAS

    - by Ben
    I've got a bit of an issue that I'm hoping you can help me with. I have an Iomega ix4 as my NAS. This runs Linux and each drive in the box has 2 partitions: one for the OS and RAID info, and the second for the actual data. I had it configured as RAID5. Recently one of the drives failed. At this point all of the data was available, it was just reporting a failed drive. I had a drive of the same capacity (although not the exact same spec) which I swapped in place of the failed drive. It recognised it, and started to rebuild the data protection. So far so good ... or so I thought. The next day, after data protection had finished reconstructing, the NAS was telling me that 4 new drives had been added, and wanted confirmation to overwrite the data. Obviously I declined to do this. I swapped the failed drive back in again, in the hope that it would return to its previous state of the data being accessible, but one failed disk. However it didn't - it still tells me that the NAS has 4 new drives in it. I am hopeful that the actual data is untouched, so what I need to do is get it to rebuild the RAID without touching the data on the disks. I have ssh access, and have run stuff like mdadm --examine to see what I can find. The mdadm.conf file has no entry in the "definitions of existing MD arrays" section. I have not run any actual rebuilding commands as yet, because this is entering an area which I am out of my depth in. Please can someone advise the best way of getting my data? Thanks.

  • Nginx redirect all request that does not match a file to a php file

    - by cyrbil
    I'm trying to get all request to: http://mydomain.com/downloads/* redirect to http://mydomain.com/downloads/index.php except if the requested file exist in /downloads/ ex: http://mydomain.com/downloads = /downloads/index.php http://mydomain.com/downloads/unknowfile = /downloads/index.php http://mydomain.com/downloads/existingfile = /downloads/existingfile My current problem is I have either the redirection to php working but static files not served or the opposite. Here is my current vhost conf: (which redirect fine but static files are send to php and fail) server { listen 80; ## listen for ipv4; this line is default and implied server_name domain.com; root /data/www; index index.php index.html; location / { try_files $uri $uri/ /index.html; } error_page 404 /404.html; # redirect server error pages to the static page /50x.html error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/www; } location ^~ /downloads { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_index index.php; include fastcgi_params; try_files $uri @downloads; } location @downloads { rewrite ^ /downloads/index.php; } # pass the PHP scripts to FastCGI server # location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } } Precision: static files are symlinks created by /downloads/index.php Thank you for your help.

  • Using the Data Form Web Part (SharePoint 2010) Site Agnostically!

    - by David Jacobus
    Originally posted on: http://geekswithblogs.net/djacobus/archive/2013/10/24/154465.aspxAs a Developer whom has worked closely with web designers (Power users) in a SharePoint environment, I have come across the issue of making the Data Form Web Part reusable across the site collection! In SharePoint 2007 it was very easy and this blog pointed the way to make it happen: Josh Gaffey's Blog. In SharePoint 2010 something changed! This method failed except for using a Data Form Web Part that pointed to a list in the Site Collection Root! I am making this discussion relative to a developer whom creates a solution (WSP) with all the artifacts embedded and the user shouldn’t have any involvement in the process except to activate features. The Scenario: 1. A Power User creates a Data Form Web Part using SharePoint Designer 2010! It is a great web part the uses all the power of SharePoint Designer and XSLT (Conditional formatting, etc.). 2. Other Users in the site collection want to use that specific web part in sub sites in the site collection. Pointing to a list with the same name, not at the site collection root! The Issues: 1. The Data Form Web Part Data Source uses a List ID (GUID) to point to the specific list. Which means a list in a sub site will have a list with a new GUID different than the one which was created with SharePoint Designer! Obviously, the List needs to be the same List (Fields, Content Types, etc.) with different data. 2. How can we make this web part site agnostic, and dependent only on the lists Name? I had this problem come up over and over and decided to put my solution forward! The Solution: 1. Use the XSL of the Data Form Web Part Created By the Power User in SharePoint Designer! 2. Extend the OOTB Data Form Web Part to use this XSL and Point to a List by name. The solution points to a hybrid solution that requires some coding (Developer) and the XSL (Power User) artifacts put together in a Visual Studio SharePoint Solution. Here are the solution steps in summary: 1. Create an empty SharePoint project in Visual Studio 2. Create a Module and Feature and put the XSL file created by the Power User into it a. Scope the feature to web 3. Create a Feature Receiver to Create the List. The same list from which the Data Form Web Part was created with by the Power User. a. Scope the feature to web 4. Create a Web Part extending the Data Form Web a. Point the Data Form Web Part to point to the List by Name b. Point the Data Form Web Part XSL link to the XSL added using the Module feature c. Scope The feature to Site i. This is because all web parts are in the site collection web part gallery. So in a Narrative Summary: We are creating a list in code which has the same name and (site Columns) as the list from which the Power User created the Data Form Web Part Using SharePoint Designer. We are creating a Web Part in code which extends the OOTB Data Form Web Part to point to a list by name and use the XSL created by the Power User. Okay! Here are the steps with images and code! At the end of this post I will provide a link to the code for a solution which works in any site! I want to TOOT the HORN for the power of this solution! It is the mantra a use with all my clients! What is a basic skill a SharePoint Developer: Create an application that uses the data from a SharePoint list and make that data visible to the user in a manner which meets requirements! Create an Empty SharePoint 2010 Project Here I am naming my Project DJ.DataFormWebPart Create a Code Folder Copy and paste the Extension and Utilities classes (Found in the solution provided at the end of this post) Change the Namespace to match this project The List to which the Data Form Web Part which was used to make the XSL by the Power User in SharePoint Designer is now going to be created in code! If already in code, then all the better! Here I am going to create a list in the site collection root and add some data to it! For the purpose of this discussion I will actually create this list in code before using SharePoint Designer for simplicity! So here I create the List and deploy it within this solution before I do anything else. I will use a List I created before for demo purposes. Footer List is used within the footer of my master page. Add a new Feature: Here I name the Feature FooterList and add a Feature Event Receiver: Here is the code for the Event Receiver: I have a previous blog post about adding lists in code so I will not take time to narrate this code: using System; using System.Runtime.InteropServices; using System.Security.Permissions; using Microsoft.SharePoint; using DJ.DataFormWebPart.Code; namespace DJ.DataFormWebPart.Features.FooterList { /// <summary> /// This class handles events raised during feature activation, deactivation, installation, uninstallation, and upgrade. /// </summary> /// <remarks> /// The GUID attached to this class may be used during packaging and should not be modified. /// </remarks> [Guid("a58644fd-9209-41f4-aa16-67a53af7a9bf")] public class FooterListEventReceiver : SPFeatureReceiver { SPWeb currentWeb = null; SPSite currentSite = null; const string columnGroup = "DJ"; const string ctName = "FooterContentType"; // Uncomment the method below to handle the event raised after a feature has been activated. public override void FeatureActivated(SPFeatureReceiverProperties properties) { using (SPWeb spWeb = properties.GetWeb() as SPWeb) { using (SPSite site = new SPSite(spWeb.Site.ID)) { using (SPWeb rootWeb = site.OpenWeb(site.RootWeb.ID)) { //add the fields addFields(rootWeb); //add content type SPContentType testCT = rootWeb.ContentTypes[ctName]; // we will not create the content type if it exists if (testCT == null) { //the content type does not exist add it addContentType(rootWeb, ctName); } if ((spWeb.Lists.TryGetList("FooterList") == null)) { //create the list if it dosen't to exist CreateFooterList(spWeb, site); } } } } } #region ContentType public void addFields(SPWeb spWeb) { Utilities.addField(spWeb, "Link", SPFieldType.URL, false, columnGroup); Utilities.addField(spWeb, "Information", SPFieldType.Text, false, columnGroup); } private static void addContentType(SPWeb spWeb, string name) { SPContentType myContentType = new SPContentType(spWeb.ContentTypes["Item"], spWeb.ContentTypes, name) { Group = columnGroup }; spWeb.ContentTypes.Add(myContentType); addContentTypeLinkages(spWeb, myContentType); myContentType.Update(); } public static void addContentTypeLinkages(SPWeb spWeb, SPContentType ct) { Utilities.addContentTypeLink(spWeb, "Link", ct); Utilities.addContentTypeLink(spWeb, "Information", ct); } private void CreateFooterList(SPWeb web, SPSite site) { Guid newListGuid = web.Lists.Add("FooterList", "Footer List", SPListTemplateType.GenericList); SPList newList = web.Lists[newListGuid]; newList.ContentTypesEnabled = true; var footer = site.RootWeb.ContentTypes[ctName]; newList.ContentTypes.Add(footer); newList.ContentTypes.Delete(newList.ContentTypes["Item"].Id); newList.Update(); var view = newList.DefaultView; //add all view fields here //view.ViewFields.Add("NewsTitle"); view.ViewFields.Add("Link"); view.ViewFields.Add("Information"); view.Update(); } } } Basically created a content type with two site columns Link and Information. I had to change some code as we are working at the SPWeb level and need Content Types at the SPSite level! I’ll use a new Site Collection for this demo (Best Practice) keep old artifacts from impinging on development: Next we will add this list to the root of the site collection by deploying this solution, add some data and then use SharePoint Designer to create a Data Form Web Part. The list has been added, now let’s add some data: Okay let’s add a Data Form Web Part in SharePoint Designer. Create a new web part page in the site pages library: I will name it TestWP.aspx and edit it in advanced mode: Let’s add an empty Data Form Web Part to the web part zone: Click on the web part to add a data source: Choose FooterList in the Data Source menu: Choose appropriate fields and select insert as multiple item view: Here is what it look like after insertion: Let’s add some conditional formatting if the information filed is not blank: Choose Create (right side) apply formatting: Choose the Information Field and set the condition not null: Click Set Style: Here is the result: Okay! Not flashy but simple enough for this demo. Remember this is the job of the Power user! All we want from this web part is the XLS-Style Sheet out of SharePoint Designer. We are going to use it as the XSL for our web part which we will be creating next. Let’s add a web part to our project extending the OOTB Data Form Web Part. Add new item from the Visual Studio add menu: Choose Web Part: Change WebPart to DataFormWebPart (Oh well my namespace needs some improvement, but it will sure make it readily identifiable as an extended web part!) Below is the code for this web part: using System; using System.ComponentModel; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using System.Text; namespace DJ.DataFormWebPart.DataFormWebPart { [ToolboxItemAttribute(false)] public class DataFormWebPart : Microsoft.SharePoint.WebPartPages.DataFormWebPart { protected override void OnInit(EventArgs e) { base.OnInit(e); this.ChromeType = PartChromeType.None; this.Title = "FooterListDF"; try { //SPSite site = SPContext.Current.Site; SPWeb web = SPContext.Current.Web; SPList list = web.Lists.TryGetList("FooterList"); if (list != null) { string queryList1 = "<Query><Where><IsNotNull><FieldRef Name='Title' /></IsNotNull></Where><OrderBy><FieldRef Name='Title' Ascending='True' /></OrderBy></Query>"; uint maximumRowList1 = 10; SPDataSource dataSourceList1 = GetDataSource(list.Title, web.Url, list, queryList1, maximumRowList1); this.DataSources.Add(dataSourceList1); this.XslLink = web.Url + "/Assests/Footer.xsl"; this.ParameterBindings = BuildDataFormParameters(); this.DataBind(); } } catch (Exception ex) { this.Controls.Add(new LiteralControl("ERROR: " + ex.Message)); } } private SPDataSource GetDataSource(string dataSourceId, string webUrl, SPList list, string query, uint maximumRow) { SPDataSource dataSource = new SPDataSource(); dataSource.UseInternalName = true; dataSource.ID = dataSourceId; dataSource.DataSourceMode = SPDataSourceMode.List; dataSource.List = list; dataSource.SelectCommand = "" + query + ""; Parameter listIdParam = new Parameter("ListID"); listIdParam.DefaultValue = list.ID.ToString( "B").ToUpper(); Parameter maximumRowsParam = new Parameter("MaximumRows"); maximumRowsParam.DefaultValue = maximumRow.ToString(); QueryStringParameter rootFolderParam = new QueryStringParameter("RootFolder", "RootFolder"); dataSource.SelectParameters.Add(listIdParam); dataSource.SelectParameters.Add(maximumRowsParam); dataSource.SelectParameters.Add(rootFolderParam); dataSource.UpdateParameters.Add(listIdParam); dataSource.DeleteParameters.Add(listIdParam); dataSource.InsertParameters.Add(listIdParam); return dataSource; } private string BuildDataFormParameters() { StringBuilder parameters = new StringBuilder("<ParameterBindings><ParameterBinding Name=\"dvt_apos\" Location=\"Postback;Connection\"/><ParameterBinding Name=\"UserID\" Location=\"CAMLVariable\" DefaultValue=\"CurrentUserName\"/><ParameterBinding Name=\"Today\" Location=\"CAMLVariable\" DefaultValue=\"CurrentDate\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_firstrow\" Location=\"Postback;Connection\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_nextpagedata\" Location=\"Postback;Connection\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_adhocmode\" Location=\"Postback;Connection\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_adhocfiltermode\" Location=\"Postback;Connection\"/>"); parameters.Append("</ParameterBindings>"); return parameters.ToString(); } } } The OnInit method we use to set the list name and the XSL Link property of the Data Form Web Part. We do not have the link to XSL in our Solution so we will add the XSL now: Add a Module in the Visual Studio add menu: Rename Sample.txt in the module to footer.xsl and then copy the XSL from SharePoint Designer Look at elements.xml to where the footer.xsl is being provisioned to which is Assets/footer.xsl, make sure the Web parts xsl link is pointing to this url: Okay we are good to go! Let’s check our features and package: DataFormWebPart should be scoped to site and have the web part: The Footer List feature should be scoped to web and have the Assets module (Okay, I see, a spelling issue but it won’t affect this demo) If everything is correct we should be able to click a couple of sub site feature activations and have our list and web part in a sub site. (In fact this solution can be activated anywhere) Here is the list created at SubSite1 with new data It. Next let’s add the web part on a test page and see if it works as expected: It does! So we now have a repeatable way to use a WSP to move a Data Form Web Part around our sites! Here is a link to the code: DataFormWebPart Solution

  • Implementing Linked Lists in C#

    - by nijhawan.saurabh
    Why? The question is why you need Linked Lists and why it is the foundation of any Abstract Data Structure. Take any of the Data Structures - Stacks, Queues, Heaps, Trees; there are two ways to go about implementing them - Using Arrays Using Linked Lists Now you use Arrays when you know about the size of the Nodes in the list at Compile time and Linked Lists are helpful where you are free to add as many Nodes to the List as required at Runtime.   How? Now, let's see how we go about implementing a Simple Linked List in C#. Note: We'd be dealing with singly linked list for time being, there's also another version of linked lists - the Doubly Linked List which maintains two pointers (NEXT and BEFORE).   Class Diagram Let's see the Class Diagram first:     Code     1 // -----------------------------------------------------------------------     2 // <copyright file="Node.cs" company="">     3 // TODO: Update copyright text.     4 // </copyright>     5 // -----------------------------------------------------------------------     6      7 namespace CSharpAlgorithmsAndDS     8 {     9     using System;    10     using System.Collections.Generic;    11     using System.Linq;    12     using System.Text;    13     14     /// <summary>    15     /// TODO: Update summary.    16     /// </summary>    17     public class Node    18     {    19         public Object data { get; set; }    20     21         public Node Next { get; set; }    22     }    23 }    24         1 // -----------------------------------------------------------------------     2 // <copyright file="LinkedList.cs" company="">     3 // TODO: Update copyright text.     4 // </copyright>     5 // -----------------------------------------------------------------------     6      7 namespace CSharpAlgorithmsAndDS     8 {     9     using System;    10     using System.Collections.Generic;    11     using System.Linq;    12     using System.Text;    13     14     /// <summary>    15     /// TODO: Update summary.    16     /// </summary>    17     public class LinkedList    18     {    19         private Node Head;    20     21         public void AddNode(Node n)    22         {    23             n.Next = this.Head;    24             this.Head = n;    25     26         }    27     28         public void printNodes()    29         {    30     31             while (Head!=null)    32             {    33                 Console.WriteLine(Head.data);    34                 Head = Head.Next;    35     36             }    37     38         }    39     }    40 }    41          1 using System;     2 using System.Collections.Generic;     3 using System.Linq;     4 using System.Text;     5      6 namespace CSharpAlgorithmsAndDS     7 {     8     class Program     9     {    10         static void Main(string[] args)    11         {    12             LinkedList ll = new LinkedList();    13             Node A = new Node();    14             A.data = "A";    15     16             Node B = new Node();    17             B.data = "B";    18     19             Node C = new Node();    20             C.data = "C";    21             ll.AddNode(A);    22             ll.AddNode(B);    23             ll.AddNode(C);    24     25             ll.printNodes();    26         }    27     }    28 }    29        Final Words This is just a start, I will add more posts on Linked List covering more operations like Delete etc. and will also explore Doubly Linked List / Implementing Stacks/ Heaps/ Trees / Queues and what not using Linked Lists.   Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Oracle GoldenGate 12c - Leading Enterprise Replication

    - by Doug Reid
    Oracle GoldenGate 12c released  on October 17th and includes several new cutting edge features that firmly establishes GoldenGate's leader position in the data replication space.   In fact, this release more than doubles the performance of data delivery, supports Oracle's new multitenant database feature,  it's more secure, has more options for high availability, and has made great strides to simplify the configuration and deployment of the product.     Read through the press release if you haven't already and do not miss the quote from Cern's Eva Dafonte Perez, regarding Oracle GoldenGate 12c "….performs five times faster compared to previous GoldenGate versions and simplifies the management of a multi-tier environment" There are a variety of new and improved features in the Oracle GoldenGate 12c.  Here are the highlights: Optimized for Oracle Database 12c -  GoldenGate 12c is custom tailored to the unique capabilities of Oracle database 12c and out of the box GoldenGate 12c supports multitenant (pluggable database (PDB)) and non-consolidated deployments of Oracle Database 12c.   The naming convention used by database 12c is now in three parts (PDB-name, schema-name, and object name).  We have made changes to the GoldenGate capture process to support the new naming convention and streamlined the whole process so a single GoldenGate capture process is being used at the container level rather than at each individual PDB.  By having the capture process at the container level resource usage and the number of processes are reduced. To view a conceptual architecture diagram click here. Integrated Delivery for the Oracle Database - Leveraging a lightweight streaming API built exclusively for Oracle GoldenGate 12c, this process distributes load, auto tunes the degree of parallelism, scales better, and delivers blinding rates of changed data delivery to the Oracle database.  One of the goals for Oracle GoldenGate 12c was to reduce IT costs by simplifying the configuration and reduce the time to manage complex infrastructures.  In previous versions of Oracle GoldenGate, customers would split transaction loads by grouping tables into multiple different delivery processes (click here to view the previous method). Each delivery process executed independently and without any interaction or knowledge of other delivery processes.  This setup was complicated to configure and time consuming as the developer needed in-depth knowledge of the source and target schemas and the transaction profile. With GoldenGate 12c and Integrated Delivery we have made it easier to configure and faster to deploy.  To view a conceptual architecture diagram of integrated delivery click here Coordinated Delivery for Non-Oracle Databases - Coordinated Delivery orchestrates high-speed apply processes and simplifies the configuration of GoldenGate for non-Oracle targets. In Oracle GoldenGate 12c a single delivery process is used with multiple threads (click here) and key events, such as primary key updates, event markers, DDL, etc, are coordinated between the various threads to insure that the transactions are applied in the same sequence as they were captured, all while delivery improved performance.  Replication Between On-Premises and Cloud-Based systems. - The trend for business to utilize both on-premises and cloud-based systems is rising and businesses need to replicate data back and forth.   GoldenGate 12c can be configured in a variety of ways to provide real-time replication when unrestricted or restricted (limited ports or HTTP tunneling) networks are between on-premises and cloud-based systems.    Expanded Heterogeneity - It wouldn't be a GoldenGate release without new and improved platform support.   Release 1 includes support for MySQL 5.6 and Sybase 15.7.   Upcoming in the next release GoldenGate, support will be expanded for MS SQL Server, DB2, and Teradata. Tighter Security - Oracle GoldenGate 12c is integrated with the Oracle wallet to shield usernames and passwords using strong encryption and aliases.   Customers accustomed to using the Oracle Wallet with other Oracle products will instantly be familiar with how to use this great new feature Expanded Oracle Application and Technology Support -   GoldenGate can be used along with Oracle Coherence to enable real-time changed data feeds to the Coherence cache using Toplink and the Oracle GoldenGate JMS adapter.     Plus,  Oracle Advanced Customer Services (ACS) now offers a low downtime E-Business Suite platform and database migrations using GoldenGate as the enabling technology.  Keep tuned for more blogs on the new features and the upcoming launch webcast where we will go into these new features in more detail.   In the mean time make sure to read through our white paper "Oracle GoldenGate 12c Release 1 New Features Overview"

  • How to hide files in Apache 2.2 WebDAV Directory listings

    - by mdornsf
    I use Apache 2.2 as WebDAV file server to a bunch of Mac and MS Windows clients. Unfortunately both clutter the filesystem with files like .DS_Store or thumbs.db. Since hte files distract my users i want to hide them from directory listings. Unfortunately the standard way of hiding files in Apache (via IndexIgnore) seems not to work via WebDAV. Is there any other way to hide files?
