• SQL SERVER – Sharing your ETL Resources Across Applications with Ease

  - by pinaldave

  Frequently an organization will find that the same resources are used in multiple ETL applications, for example, the same database, general purpose processing logic, or file system locations.  Creating an easy way to reuse these resources across multiple applications would increase efficiency and reduce errors.  Moreover, not every ETL developer has the same skill set, and it is likely that one developer will be more adept at writing code while another is more comfortable configuring database connections.  Real productivity gains will come when these developers are able to work independently while still making their work available to others assigned to the same project.  These are the benefits of a centralized version control system. Of course, most version control systems could be used to store and serve files, but the real need is to store and serve entire ETL applications so that each developer’s ongoing work can immediately benefit from another developer’s completed work.  In other words, the version control system needs to be tightly integrated with the tools used to develop the ETL application. The following screen shot shows such a tool. Desktop ETL tool that tightly integrates with a central version control system Developers can checkout or commit entire projects or just a single artifact.  Each artifact may be managed independently so if you need to go back to an earlier version of one artifact, changes you may have made to other artifacts are not lost.  By being tightly integrated into the graphical environment used to create and edit the project artifacts, it is extremely easy and straight-forward to move your files to and from the version control system and there is no dependency on another vendor’s version control system.  The built in version control system is optimized for managing the artifacts of ETL applications. It is equally important that the version control system supports all of the actions one typically performs such as rollbacks, locking and unlocking of files, and the ability to resolve conflicts.  Note that this particular ETL tool also has the capability to switch back and forth between multiple version control systems. It also needs to be easy to determine the status of an artifact.  Not just that it has been committed or modified, but when and by whom.  Generally you must query the version control system for this information, but having it displayed within the development environment is more desirable. Who’s ETL tool works in this fashion?  Last month I mentioned the data integration solution offered by expressor software.  The version control features I described in this post are all available in their just released expressor 3.1 Standard Edition through the integration of their expressor Studio development environment with a centralized metadata repository and version control system. You can download their Studio application, which is free, or evaluate the full Standard Edition on your own hardware.  It may be worth your time.

• How to archive data from a table to a local or remote database in SQL 2005 and SQL 2008

  - by simonsabin

  Often you have the need to archive data from a table. This leads to a number of challenges 1. How can you do it without impacting users 2. How can I make it transactionally consistent, i.e. the data I put in the archive is the data I remove from the main table 3. How can I get it to perform well Points 1 is very much tied to point 3. If it doesn't perform well then the delete of data is going to cause lots of locks and thus potentially blocking. For points 1 and 3 refer to my previous posts DELETE-TOP-x-rows-avoiding-a-table-scan and UPDATE-and-DELETE-TOP-and-ORDER-BY---Part2. In essence you need to be removing small chunks of data from your table and you want to do that avoiding a table scan. So that deals with the delete approach but archiving is about inserting that data somewhere else. Well in SQL 2008 they introduced a new feature INSERT over DML (Data Manipulation Language, i.e. SQL statements that change data), or composable DML. The ability to nest DML statements within themselves, so you can past the results of an insert to an update to a merge. I've mentioned this before here SQL-Server-2008---MERGE-and-optimistic-concurrency. This feature is currently limited to being able to consume the results of a DML statement in an INSERT statement. There are many restrictions which you can find here http://msdn.microsoft.com/en-us/library/ms177564.aspx look for the section "Inserting Data Returned From an OUTPUT Clause Into a Table" Even with the restrictions what we can do is consume the OUTPUT from a DELETE and INSERT the results into a table in another database. Note that in BOL it refers to not being able to use a remote table, remote means a table on another SQL instance. To show this working use this SQL to setup two databases foo and fooArchive create database foo go --create the source table fred in database foo select * into foo..fred from sys.objects go create database fooArchive go if object_id('fredarchive',DB_ID('fooArchive')) is null begin     select getdate() ArchiveDate,* into fooArchive..FredArchive from sys.objects where 1=2       end go And then we can use this simple statement to archive the data insert into fooArchive..FredArchive select getdate(),d.* from (delete top (1)         from foo..Fred         output deleted.*) d         go In this statement the delete can be any delete statement you wish so if you are deleting by ids or a range of values then you can do that. Refer to the DELETE-TOP-x-rows-avoiding-a-table-scan post to ensure that your delete is going to perform. The last thing you want to do is to perform 100 deletes each with 5000 records for each of those deletes to do a table scan. For a solution that works for SQL2005 or if you want to archive to a different server then you can use linked servers or SSIS. This example shows how to do it with linked servers. [ONARC-LAP03] is the source server. begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d commit transaction and to prove the transactions work try, you should get the same number of records before and after. select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d rollback transaction   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive The transactions are very important with this solution. Look what happens when you don't have transactions and an error occurs   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*                     raiserror (''Oh doo doo'',15,15)') d                     select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive Before running this think what the result would be. I got it wrong. What seems to happen is that the remote query is executed as a transaction, the error causes that to rollback. However the results have already been sent to the client and so get inserted into the

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks

• How to transfer files between a remote Linux machine and a local Windows machine?

  - by Lazer

  I need to transfer files/folders between a remote machine running Linux and my local machine running Windows XP. I usually access the remote machine through ssh, and sometimes use VNC sessions. What is the easiest way to transfer a file from the remote machine to my local machine and vice versa? I think ftp should be the solution. Is there a better way? If ftp is a good option, how do I initiate the transfer? Do I need to setup ftp servers on both the machines and then transfer? What exactly needs to be done?

• x11 looks ugly while opening a remote window from ssh. Can I use GTK themes?

  - by Simon

  I use to connect to a distant computer running linux from my mac using ssh. For example I use: $ ssh -Y login@host then $ gnome-open . in order to open a nautilus window. This window do open but it looks ugly. I found here that one can install GTK themes through Macports. I installed gtk2-aurora and gtk-chtheme and chose the aurora theme successfully, but my remote windows still look ugly. Is this theme (or others) working for remote windows or is it only for local x11 windows? Is there a way to improve the look and feel of remote windows?

• Windows Server 2008 without telnet client - how to test connecting to remote ports without installing anything new?

  - by S. Cobbs

  I'm looking to see if anyone knows of slick tricks to test connections to remote server ports from Windows server 2008 and variants that don't include the telnet client installed by default. Reason being, I sometimes have clients that want to connect to port 25 for example on a remote server and say they can't. I used to run a quick test by using "telent mailserver.tld 25" or whatever to see if I could get a response on that port. I don't want to have to install the telnet client just to test this if I dont have to - are there any other native windows utilities that will allow me to connect to a remote port?

• Preloading Winforms using a Stack and Hidden Form

  - by msarchet

  I am currently working on a project where we have a couple very control heavy user controls that are being used inside a MDI Controller. This is a Line of Business app and it is very data driven. The problem that we were facing was the aforementioned controls would load very very slowly, we dipped our toes into the waters of multi-threading for the control loading but that was not a solution for a plethora of reasons. Our solution to increasing the performance of the controls ended up being to 'pre-load' the forms onto a hidden window, create a stack of the existing forms, and pop off of the stack as the user requested a form. Now the current issue that I'm seeing that will arise as we push this 'fix' out to our testers, and the ultimately our users is this: Currently the 'hidden' window that contains the preloaded forms is visible in task manager, and can be shut down thus causing all of the controls to be lost. Then you have to create them on the fly losing the performance increase. Secondly, when the user uses up the stack we lose the performance increase (current solution to this is discussed below). For the first problem, is there a way to hide this window from task manager, perhaps by creating a parent form that encapsulates both the main form for the program and the hidden form? Our current solution to the second problem is to have an inactivity timer that when it fires checks the stacks for the forms, and loads a new form onto the stack if it isn't full. However this still has the potential of causing a hang in the UI while it creates the forms. A possible solutions for this would be to put 'used' forms back onto the stack, but I feel like there may be a better way. EDIT: For control design clarification From the comments I have realized there is a lack of clarity on what exactly the control is doing. Here is a detailed explanation of one of the controls. I have defined for this control loading time as the time it takes from when a user performs an action that would open a control, until the time a control is accessible to be edited. The control is for entering Prescriptions for a patient in the system, it has about 5 tabbed groups with a total of about 180 controls. The user selects to open a new Prescription control from inside the main program, this control is loaded into the MDI Child area of the Main Form (which is a DevExpress Ribbon Control). From the time the user clicks New (or loads an existing record) until the control is visible. The list of actions that happens in the program is this: The stack is checked for the existence of a control. If the control exists it is popped off of the stack. The control is rendered on screen. This is what takes 2 seconds The control then is populated with a blank object, or with existing data. The control is ready to use. The average percentage of loading time, across about 10 different machines, with different hardware the control rendering takes about 85 - 95 percent of the control loading time. Without using the stack the control takes about 2 seconds to load, with the stack it takes about .8 seconds, this second time is acceptable. I have looked at Henry's link and I had previously already implemented the applicable suggestions. Again I re-iterate my question as What is the best method to move controls to and from the stack with as little UI interruption as possible?

• Better, simpler example of 'semantic conflict'?

  - by rhubbarb

  I like to distinguish three different types of conflict from a version control system (VCS): textual syntactic semantic A textual conflict is one that is detected by the merge or update process. This is flagged by the system. A commit of the result is not permitted by the VCS until the conflict is resolved. A syntactic conflict is not flagged by the VCS, but the result will not compile. Therefore this should also be picked up by even a slightly careful programmer. (A simple example might be a variable rename by Left and some added lines using that variable by Right. The merge will probably have an unresolved symbol. Alternatively, this might introduce a semantic conflict by variable hiding.) Finally, a semantic conflict is not flagged by the VCS, the result compiles, but the code may have problems running. In mild cases, incorrect results are produced. In severe cases, a crash could be introduced. Even these should be detected before commit by a very careful programmer, through either code review or unit testing. My example of a semantic conflict uses SVN (Subversion) and C++, but those choices are not really relevant to the essence of the question. The base code is: int i = 0; int odds = 0; while (i < 10) { if ((i & 1) != 0) { odds *= 10; odds += i; } // next ++ i; } assert (odds == 13579) The Left (L) and Right (R) changes are as follows. Left's 'optimisation' (changing the values the loop variable takes): int i = 1; // L int odds = 0; while (i < 10) { if ((i & 1) != 0) { odds *= 10; odds += i; } // next i += 2; // L } assert (odds == 13579) Right's 'optimisation' (changing how the loop variable is used): int i = 0; int odds = 0; while (i < 5) // R { odds *= 10; odds += 2 * i + 1; // R // next ++ i; } assert (odds == 13579) This is the result of a merge or update, and is not detected by SVN (which is correct behaviour for the VCS). int i = 1; // L int odds = 0; while (i < 5) // R { odds *= 10; odds += 2 * i + 1; // R // next i += 2; // L } assert (odds == 13579) The assert fails because odds is 37. So my question is as follows. Is there a simpler example than this? Is there a simple example where the compiled executable has a new crash? As a secondary question, are there cases of this that you have encountered in real code? Again, simple examples are especially welcome.

• Should I add the vcxproj.filter files to source control

  - by jschroedl

  While evaluating Visual Studio 2010 Beta 2, I see that in the converted directory my vcproj files have become vcxproj files. There are also vcxproj.filter files alongside each project which appear to contain a description of the folder structure (\Source Files, \Header Files, etc.). Do you think these filter files should be kept per-user or should the be shared across the whole dev group and checked into SCC? My current thinking is to check them in but wondered if there's any reasons not to do that or perhaps good reasons that I should definitely check them in. The obvious benefit is that the folder structures will match if I'm looking at someone else's machine but maybe they'd like to reorganize things logically??

• Databinding a multiselect ListBox in a FormView control

  - by drs9222

  I have a multiselect ListBox within a FormView. I can't figure out how to setup the databinding for it. I can populate the listbox fine. If the listbox was a single select I could use say SelectValue='<%#Bind("col")%>' and that works fine. Is there something that I can bind to for a multiselect listbox? I've tried manually DataBinding by handling the DataBinding event of the listbox and setting the selected property on the appropriate items. Unfortunately, there are no items in the listbox during the DataBinding event. The closest thing I've found is to save the value that determines what items should be selecting during DataBinding and then use that value in the FormViews DataBinding event to select the right items which seems like a hack to me. Is there a better way? EDIT: To clarify what I am currently doing... I am using the FormViews's ItemCreated event to save the FormView's DataItem. Then in the FormView's DataBound event I find the listbox and manually set the selected items. It doesn't seem right that I have to save the value like this and I assume there is a more correct way to do this that I just can't see.

• jQuery UI dialog on ASP.NET page (inside user control)

  - by marc_s

  I have a really odd behavior here: I created a little popup dialog in jQuery UI, and in my test HTML page, it works flawlessly. When I click on the button, the popup comes up, covers the background, and remains on screen until I click on one of the two buttons (OK or Cancel) provided. So now I wanted to add this into my ASP.NET 3.5 app. I wanted to add it to a GridView inside a user controls (ASCX), which is on a page (ASPX) contained inside a master page. The jQuery 1.4.2 and jQuery UI 1.8.1 scripts are referenced on the master page: <body> <form id="XXXXXX" runat="server"> <Ajax:ScriptManager ID="masterScriptManager" runat="server" ScriptMode="Auto"> <Scripts> <asp:ScriptReference Path="~/Scripts/jquery-1.4.2.min.js" /> <asp:ScriptReference Path="~/Scripts/jquery-ui-1.8.1.custom.min.js" /> </Scripts> </Ajax:ScriptManager> I had to change this to use the Ajax script manager, since adding them to the as never worked. So in my gridview, I have a column with image buttons, and when the user clicks on those, I am calling a little javascript function to show the jQuery UI dialog: function showDialog() { $("#dlg-discount").dialog('open'); $("#txtAmount").focus(); } When I run this page in MS IE 8, I get a separate page, and at the top of the page, I get the contents of my , with proper background color and all. In Firefox 3.5.6, I do get the dialog as a popup. In both cases, the dialog page/popup disappears again after a second or less - without me clicking anything! It seems similar to this question but the solution provided there doesn't work in my case. This one here also seems similar but again: the solution presented doesn't seem to work in my case... Any ideas / hints / tips on what the h** is going on here?? Thanks!

• Fancybox Auto Close, but remain user control

  - by justinw

  Hi, i've searched through the forum yet i can't find the solution. i'm refering to this thread to do the auto close function: http://groups.google.com/group/fancybox/browse_thread/thread/d09438b7... I did follow JFK's solution which works just right: 'onComplete': function() { $("#fancybox-wrap, #fancybox-overlay").delay(3000).fadeOut(); } if you don't want the user to close the box, then add modal=true The scenario is I would like the user to have the option to close the modal when they click on the [close] button or click anywhere on the overlay. I'm using the latest version of FB and jQuery on Rails. Here's my script: <script type="text/javascript"> jQuery(document).ready(function() { jQuery("#link_post").fancybox({ 'autoDimensions':false, 'width':380, 'height':50, 'title':'This message box will automatically close in 10 seconds.', 'titlePosition':'outside', 'onComplete': function() { jQuery("#fancybox-wrap, #fancybox- overlay").delay(10000).fadeOut(); } }); }); </script> However, when i clicked on the close button, the title and close button will fade away, but the FB's content and overlay are still there! it will only fade away after 10 seconds. So, my question is how to overwrite the 'onComplete' function if user clicks on the close button before it automatically closes?

• C# WinForms ErrorProvider Control

  - by Barry

  Hi Does anyone know if there is a way to get a list of controls that have the ErrorProvider icon active. ie. any controls that failed validation. I'm trying to avoid looping all controls in the form. I'd like to display some sort of message indicating how many errors there are on the form. As my form contains tabs I'm trying to make it apparent to the user that errors may exist on inactive tabs and they need to check all tabs. Thanks Barry

• WPF ListView get GridViewColumn from control inside DataTemplate

  - by ragi

  Example: <ListView Name="lvAnyList" ItemsSource="{Binding}"> <ListView.View> <GridView> <GridViewColumn Header="xx" DisplayMemberBinding="{Binding XX}" CellTemplate="{DynamicResource MyDataTemplate}"/> <GridViewColumn Header="yy"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding YY}" /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> If I access the TextBlock inside DataTemplate I will have access to information about the bound path. But I don't know how to find (starting from the TextBlock) its containing GridViewColumn (which is in the GridViewRowPresenter columns list) and compare it to the grid's GridViewColumn (from GridViewHeaderRowPresenter column list) to get the header's name. At the end I should have the pairs: xx-XX, yy-YY I can find a list of all TextBlocks inside ListView by using this: GridViewRowPresenter gvrp = ControlAux.GetVisualDescendants<GridViewRowPresenter>(element).FirstOrDefault(); IEnumerable<TextBlock> entb = GetVisualDescendants<TextBlock>(gvrp); I can find a list of all GridViewColumnHeaders: GridViewHeaderRowPresenter gvhrp = ControlAux.GetVisualDescendants<GridViewHeaderRowPresenter>(element).FirstOrDefault(); And I cannot find the connection between the TextBlocks and the GridViewColumns... I hope this is understandable.
