  • 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.

  • I'm looking to learn how to apply traditional animation techniques to my graphics engine - are there any tutorials or online-resources that can help?

    - by blueberryfields
    There are many traditional animation techniques - such as blurring of motion, motion along an elliptical curve rather than a straight line, counter-motion before beginning of movement - which help with creating the appearance of a realistic 3D animated character. I'm looking to incorporate tools and short cuts for some of these into my graphics engine, to make it easier for my end users to use these techniques in their animations. Is there a good resource listing the techniques and the principles behind them, especially how they might apply to a graphics engine or 3D animation?

  • 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.

  • MKMapView memory usage grows out of control with setRegion: calls

    - by Kurt
    Hi, I have a single MKMapView instance that I have programmatically added to a UIView. As part of the UI, the user can cycle through a list of addresses and the map view is updated to show the correct map for each address as the user goes through them. I create the map view once, and simply change what it displays with setRegion:animated:. The problem is that each time the map is changed to show a new address, the memory usage of my program increases by 200K-500K (as reported by Memory Monitor in Instruments). According to Object Allocations, it appears that a lot of 1.0K Mallocs are happening each time, and the Extended Detail pane for these 1.0K allocations shows that the Responsible Caller is convert_image_data and the Extended Detail pane shows that this is the result of [MKMapTileView drawLayer:inContext:]. So, seems likely to me that the memory usage is due to MKMapView not freeing memory it uses to redraw the map each time. In fact, when I don't display the map at all (by not even adding it as a subview of my main UIView) but still cycle through the addresses (which changes various UILabels and other displayed info) the memory usage for the app does NOT increase. If I add the map view but never update it with setRegion:, the memory also does NOT increase when changing to a new address. One more bit of info: if I go to a new address (and therefore ask the map to display the new address) the memory jumps as described above. However, if I go back to an address that was already displayed, the memory does not jump when the map redraws with the old address. Also, this happens on iPad (real device) with 3.2 and on iPhone (again, real device) with 3.1.2. Here's how I initialize the MKMapView (I only do this once): CGRect mapFrame; mapFrame.origin.y = 460; // yes, magic numbers. just for testing. mapFrame.origin.x = 0; mapFrame.size.height = 500; mapFrame.size.width = 768; mapView = [[MKMapView alloc] initWithFrame:mapFrame]; mapView.delegate = self; [self.view insertSubview:mapView atIndex:0]; And in response to the user selecting an address, I set the map like so: MKCoordinateRegion region; MKCoordinateSpan span; span.latitudeDelta=kStreetMapSpan; // 0.003 span.longitudeDelta=kStreetMapSpan; // 0.003 region.center = address.coords; // coords is CLLocationCoordinate2D region.span = span; mapView.region.span = span; [mapView setRegion:region animated:NO]; Any thoughts? I've scoured the net but haven't seen mention of this problem, and I've reached the limits of my Instruments knowledge. Thanks for any ideas.
