• Automatic incremental SQL Script generation for incremental, nightly builds when using Team Build in

  - by Steve Johnson

  hi all, hope that everybody here is OK. We are using VS 2008 as development tool, TFS 2008 as version control as well as build automation. Some of our developer use dbpro for databases changes and some use SQL Server management studio. I am trying to automate build for Web Application built using C# and VB.Net. Our scenario is such that we have a central database to which our web application connects. Whenever we supply our clients with a new functionality or a bug fix, we supply them incremental builds. The SQL script is checked into source control for every incremental build when they have made and tested there changes on our central DB Server. I want to generate Differential script that can be run at the client as an incremental update script. Now to come about it is a problem. Sometimes our developers tend to forget the database change-sets and the script in the source control is missing an SP or a two. Also, sometimes we need to insert default data into some of the tables that have strict stringent values and not test values. Like a table that contains Services provided by the panel, we add a new service name, signature, credentials and service address, etc etc in the ServiceTable. Besides this many other tables may have test data that may not be needed. If we use DataCompare, it will generate changeset for required data (important for client to enable certain services) and our test data that was added to the database as a result of our testing of the functionality or bug fix. Currently i am using SQLSchemaCompareTask (from Visual Studio 2008 Team Database Professional Power Tools API) in the TFSBuild.proj file of the build definition for TFS 2008. Using SQLSchemaCompareTask, the script generated contains database names like [dbo]. etc which are not desired as the script fails when run against SQL Server 2000 databses (Some of our client still use SQL Server 2000) databases as teh backend of the application. Also default data can't be generated by this process. To overcome this problem, i have to come up with a solution that can compare databases and generate script automatically that does not have to be manually reviewed again before being sent to the client. Please suggest effective methodology of such SQL script generation and suggest whether two different databases may be used or something ? Is there any toolkit or api that can enable build automation for SQL Server databases? Thank you all. Regards Steve

• PHPExcel set specific headers for file format

  - by Asif

  Hi, While googling I found two different sets of headers that need to be set when outputting excel generated in different file format. for e.g. For Type "Excel5" headers are: header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download");; header("Content-Disposition: attachment;filename=$filename"); header("Content-Transfer-Encoding: binary "); For Type "Excel2007" headers are: header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); header('Content-Disposition: attachment;filename="myfile.xlsx"'); header('Cache-Control: max-age=0'); My question: is there need to set up different headers for each file type as there are other file types also CSV, HTML and PDF?

• Setting width of UISegmentedControl after removing a segment

  - by David Foster

  I have a UISegmentedControl of width 280. In code, I need to remove the third segment, set the UISegmentedControl's width to 200 and then re-centralise. By configuring the springs and struts in IB, I have set the segmented control up such that when I set the width directly it will automatically re-centre. However, when setting the width in code, is it true I need to set it via -setFrame? If this is the case, then I also need to set its X origin, which renders my auto-centralising redundant. My code: [segmentedControl removeSegmentAtIndex:2 animated:NO]; [segmentedControl setFrame:CGRectMake(segmentedControl.frame.origin.x + ((segmentedControl.frame.size.width - TWO_SEGMENT_SEGMENTED_CONTROL_WIDTH) / 2), segmentedControl.frame.origin.y, TWO_SEGMENT_SEGMENTED_CONTROL_WIDTH, segmentedControl.frame.size.height)]; This works, but seems hugely overblown for my purposes. Is there really no simpler way to set solely the width of the control in code?

• Implement a HierarchicalDataBoundControl for ASP.NET

  - by Breadtruck

  I want to implement a Hierarchical data bound control for ASP.NET. I used Implementing IHierarchy Support Into Your Custom Collection as a basis to create my hierarchical collection. I also created a HierarchicalDataSourceControl for the collection. Everything works: I can bind it to an ASP.NET TreeView and it renders the data correctly. However, I'm stuck on the HierarchicalDataBoundControl. I found examples, but I am still too new at c# / .Net to understand them. I don't quite understand how to implement the examples: Rendering a databound UL menu nor HierarchicalDataBoundControl Class Does anyone have any tips, or better examples of implementing a control like this?

• Is DataGrid a necessity in WPF?

  - by Jobi Joy

  I have seen a lot of discussions going on and people asking about DataGrid for WPF and complaining about Microsoft for not having one with their WPF framework till date. We know that WPF is a great UI technology and have the Concept of ItemsControl,DataTemplate, etc,etc to make great UX. Even WPF has got a more closely matching control- ListView, which can be easily templated to give better UX than a traditional Datagrid like display. And I would say a readymade DataGrid control will kill or hide a lot of creativity and it surely will decrease the innovations in User Experience field. So what is your opinion about the need of DataGrid in WPF as a Framework component? If you feel it is necessary then is it just because the world is so used to the DatGrid way of data display for many years? Some other threads having the discussion about DatGrid are here and here Link to WPF ToolKit - Latest WPF DatGrid

• RadControl DateTimePicker Selecting new time doesn't remove highlight from previous selection

  - by Jason Beck

  This is not browser specific - the behavior exists in Firefox and IE. The RadControl is being used within a User Control in a SiteFinity site. Very little customization has been done to the control. <telerik:RadDateTimePicker ID="RadDateTimePicker1" runat="server" MinDate="2010/1/1" Width="250px"> <ClientEvents></ClientEvents> <TimeView starttime="08:00:00" endtime="20:00:00" interval="02:00:00"></TimeView> <DateInput runat="server" ID="DateInput"></DateInput> </telerik:RadDateTimePicker> protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { RadDateTimePicker1.MinDate = DateTime.Now; } }

• UiElement from abstract class

  - by plotnick

  I placed a control into a grid. let's say the control is derived from public class 'ButBase' which is derived in its turn from System.Windows.Controls.Button. The code normally compiles and app works just fine. But there's something really annoying. When you try to switch to xaml-design tab it will say 'The document root element is not supported by the visual designer', which is normal and I'm totally okay with that, but the thing is, that all the xaml code is underlined and VS2010 says: 'Cannot create an instance of ButBase' although still normally compiles and able to run. I've tried the same code in VS2008, it said that needs to see a public parameterless constructor in the ButBase, and even after I put one it showed the same error. What do I miss here?

• Rendering a derived partial view with Html.RenderPartial

  - by FreshCode

  Calling Html.RenderPartial("~/Views/Payments/MyControl.ascx"); from a view works if Method.ascx is a control that directly inherits System.Web.Mvc.ViewUserControl. However, if the control inherits a new class that derives from System.Web.Mvc.ViewUserControl, the call to Html.RenderPartial("~/Views/Payments/MyDerivedControl.ascx"); fails, reporting that no such view exists. Example derived ViewUserControl: class MyDerivedControl : System.Web.Mvc.ViewUserControl { public Method() { ViewData["SomeData"] = "test"; } } Is there a workaround, or is there another way I should be doing this? Perhaps an HTML helper?

• How do you exclude folders on get operation for sourcecontrol in CruiseControl.NET

  - by Jon

  I have a cruisecontrol.net project which currently doesn't monitor a source safe project. It is forced manually. Within the source control block however I want to be able to exclude the 'get' operation of a certain folder. I know there is a ExclusionFilter feature on a source control block in the config file, but I think that this excludes the sub folder from being monitored not from being retrieved from the repository. Can anyone confirm this is the case, or help me find out how I can achieve this? I'm using CCNet 1.4 and SourceSafe

• How can I prevent Telerik RadChart from generating an onerror attribute?

  - by Sean McMillan

  We're using the Telerik Rad Controls for ASP.Net Ajax on an ASP.Net MVC project. The RadChart generates the following HTML: <img onerror="if(confirm('Error loading RadChart image.\nYou may also wish to check the ASP.NET Trace for further details.\nDisplay stack trace?'))window.location.href=this.src;" src="ChartImage.axd?UseSession=true&amp;ChartID=e25ad666-e05b-4a92-ac0c-4f2c729b9382_chart_ctl00$MainContent$AverageCTMChart&amp;imageFormat=Png&amp;random=0.501658702968461" usemap="#imctl00_MainContent_AverageCTMChart" style="border-width: 0px;" alt=""> I'd like to remove the onerror attribute; I don't really want the customers being offered the option to see a stack trace if something goes wrong. I can't see any way to control the markup that this control generates. Google searches provide no help. Has anyone dealt with this before? How do I remove the onerror attribute?

• Whats the KeyCode for overwriting a text in TextBox in winforms

  - by Ragha J

  I have a custom control which extends from TextBox. In the KeyDown event of the control I have access to the KeyCode property of keyEventArgs If the text in the textbox is selected and some other text is typed on top of it, the keyCodes that I am getting in the KeyDown event are different each time and in the KeyPress event I get the actual value. For ex: If the textbox has value 1234 and now I select 1234 and type 5 on top of it, I want to to be able to know in any of the events by some key combination that the old value 1234 is gone and the new value of the textbox is 5.

• Nice shadow effect in text (UISegmentedControl)

  - by Matthias

  Hi, I would like to bring some color to the texts of my UISegmentedControl. So, I've searched a bit about this topic, but it seems to be not possible out-of-the-box. But I found this nice blog post (link text), how to build an image out of a custom text and then assign it to the segemented control. Works fine, but the text in these created images do not have this nice little shadow effect as the original ones. So, does anyone know, how to create such a shadow effect? I guess, Apple does the same (building an image for the text) with the standard segmenented control. Thanks for your help. Regards Matthias

• Using GridSplitter in a Xaml file for both Silverlight and WPF

  - by Daniel Plaisted

  I have a Xaml file which is used in a project which can be built for both Silverlight and WPF. I want to use the GridSplitter control. However, this control is in different Xaml namespaces on Silverlight and desktop WPF. In WPF, the namespace is: http://schemas.microsoft.com/winfx/2006/xaml/presentation On Silverlight, it is: http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk So if the xaml code is <GridSplitter/>, it will work on WPF but not Silverlight, and if the code is <sdk:GridSplitter/>, it will work on Silverlight but not WPF. Is there a way to write this so that it works on both platforms?

• creating new usercntrols at runtime in ASP.NET MVC

  - by Paul Connolly

  Hi everyone, My situation is that the user is creating an entity on my site which contains the particlars of the driectors of that company, name address etc.. The Director form is a separate user control with the appropriate textboxes etc. At run time we don't know how many of these directors there will be so I need one to be able to use something like an "ADD DIRECTOR" or "DELETE DIRECTOR" button which will present or delete the another usercontrol to add the additional director. Currently I am trying to make this happen within a pane of the JQuery Accordion control. I have looked many places for how to do this but to no avail. Can anyone tell me where I might find some inforamation about how I can do this? All the best Paul

• What's the best way to create a Windows Mobile application with multiple screens in C#

  - by Joseph Earl

  I am creating a Windows Mobile Application in C# and Visual Studio 2008. The application will have 5-6 main 'screens'. There will also be bar (/area) with information (e.g. a title, whether the app is busy, etc) above the screens, and a toolbar (or similar control) below the screens with 5-6 buttons (with images) to change the active screen (i.e. the screens will share the top bar and toolbar) What is the best way to implement this? Use multiple forms, and just include the toolbar and top-bar in each Use a single form and something like the Tab control (but customised) to contain the screens Something else? Keeping in mind a) memory usage and b) time to switch screens. Thanks in advance. Any links, pointers etc are much appreciated.

• WinForms HTML visualizing controls comparison

  - by DarkDeny

  Hello all! I am working on some project which requires some HTML visualizing control (WinForms). Currently I am aware only of two such a controls: AxWebBrowser (as far as I understand this is IE-based ActiveX control for winforms) Nabu HTMLView (open source library with visualizing capabilities). Are there any other choices? What are their cons and pros? How configurable they are? For example I want to disable navigation and scripts, hook onto loading methods to override resources loading and so on.

• From iPhone OS to cocoa on OSX...

  - by David

  Hi - this is quite a basic OSX/cocoa question. I come from an iPhone OS development background. I'm now trying to write apps for OSX, but I don't understand where cocoa on OSX decides where the program gets control. I can see the main function, but where does program control go from there? Say for example I want to programatically create a window with an NSView in it once the app has finished launching - how would I do that? There is no app delegate created that I can see, in iPhone OS I would wait for the - (void) applicationDidFinishLaunching:(UIApplication *)application method to be called. I really don't want to use the Interface Builder or NIB files to setup my window/view. How would I go about this? Any help would be much appreciated - Cheers, David

• ISQL Perform instruction: after editadd editupdate of table vs. after add update of table

  - by Frank Computer

  INFORMIX-SQL 7.3 Perform Screens: According to documentation, in an "after editadd editupdate of table" control block, its instructions are executed before the row is added or updated to the table, whereas in an "after add update of table" control block, its instructions are executed after the row has been added or updated to the table, supposedly meaning that any instructions which would alter values of field-tags linked to table.columns would not be committed to the table, but field-tags linked to displayonly fields will change?.. However, when using "after add update of table" I placed instructions which alter values for field-tags linked to table.columns and their displayed and committed values also changed!.. I would have thought that an "after add update of table" would only alter displayonly fields.

• Does my fat-client application belong in the MVC pattern?

  - by boatingcow

  The web-based application I’m currently working on is growing arms and legs! It’s basically an administration system which helps users to keep track of bookings, user accounts, invoicing etc. It can also be accessed via a couple of different websites using a fairly crude API. The fat-client design loosely follows the MVC pattern (or perhaps MVP) with a php/MySQL backend, Front Controller, several dissimilar Page Controllers, a liberal smattering of object-oriented and procedural Models, a confusing bunch of Views and templates, some JavaScripts, CSS files and Flash objects. The programmer in me is a big fan of the principle of “Separation of Concerns” and on that note, I’m currently trying to figure out the best way to separate and combine the various concerns as the project grows and more people contribute to it. The problem we’re facing is that although JavaScript (or Flash with ActionScript) is normally written with the template, hence part of the View and decoupled from the Controller and Model, we find that it actually encompasses the entire MVC pattern... Swap an image with an onmouseover event - that’s Behaviour. Render a datagrid - we’re manipulating the View. Send the result of reordering a list via AJAX - now we’re in Control. Check a form field to see if an email address is in a valid format - we’re consulting the Model. Is it wise to let the database people write up the validation Model with jQuery? Can the php programmers write the necessary Control structures in JavaScript? Can the web designers really write a functional AJAX form for their View? Should there be a JavaScript overlord for every project? If the MVC pattern could be applied to the people instead of the code, we would end up with this: Model - the database boffins - “SELECT * FROM mind WHERE interested IS NULL” Control - pesky programmers - “class Something extends NothingAbstractClass{…}” View - traditionally the domain of the graphic/web designer - “” …and a new layer: Behaviour - interaction and feedback designer - “CSS3 is the new black…” So, we’re refactoring and I’d like to stick to best practice design, but I’m not sure how to proceed. I don’t want to reinvent the wheel, so would anyone have any hints or tips as to what pattern I should be looking at or any code samples from someone who’s already done the dirty work? As the programmer guy, how can I rewrite the app for backend and front end whilst keeping the two separate? And before you ask, yes I’ve looked at Zend, CodeIgnitor, Symfony, etc., and no, they don’t seem to cross the boundary between server logic and client logic!

• WPF Binding issues

  - by Nitin Chaudhari

  I have WPF window which binds a local Dependency property to a property of my usercontrol. So now I see the value which the window gave me in my usercontrol. I achieve this by setting DataContext of window to the window itself Now once the window is loaded i set the DataContext of usercontrol to a ViewModel class, and at some point of time(based on user action) the control changes values in the control. All fine so far. But now the changed value is not reflected in Windows dependency property. How I can resolve this issue?

• Setting the background color of WPF TabControl inactive tabs

  - by David Veeneman

  Is there a simple way to set the background brush of all inactive tabs in a WPF TabControl? I want to emulate the look of VS 2010 on a TabControl--the background color of the control's inactive tabs should match the background color of the window in which the TabControl is sited, so that you see only the text of the tab, and not the tab itself. I know it will take a ControlTemplate to do it; I am trying to figure out what to put in the control template. Put another way, How do I specify that a particular brush should be applied to all inactive tabs? Thanks for your help.

• Exceptions using CruiseControl.NET

  - by Andy

  I recently updated to CC.NET 1.5 and I'm now getting some strange exceptions. On one project I get: - ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: Can't create a character converter from native encoding to 'UTF-8' This happens when CC is checking a subversion repository for any mods. If I run the actual command line CC says is failing it works and returns an empty XML (there are no mods). Some other projects also fail to check mods with another "Source control operation failed" exception but no further info. Again the command is an "svn log" which when run from command line works ok. I'm using subversion 1.4.5 client side and my source repository exists on a separate box than my build server. Anyone got any ideas?
