Link to RSS/Atom feed, relative, doesn't work in Firefox

- by Adrian Smith

I have a weird problem. I generate a HTML page, hosted let's say at http://www.x.com/stuff which contains <head> <link type="application/atom+xml" rel="alternate" href="/stuff/feed"/> .. </head> The result is: In IE7 all works well - you can click on the feed icon in the browser and the feed is displayed In Firefox, view source, click on the linked /stuff/feed and you see the source of the feed, so that works as expected In Firefox, view the page (not source), then click on the feed icon in the address bar, I get an error that it can't retrieve the URL feed://http//www.x.com/stuff/feed So the problem is, that it's appending feed:// to the front of the URL and then taking out the colon : after the http. I understand that feed: is HTTP anyway so perhaps the adding of that isn't a big problem. But anyway, the fact is, that URL Firefox generates out of my <link> tag doesn't work. I have considered making the URL absolute, but I haven't found any evidence that those URLs have to be absolute, nor can I understand why that would be the case. And for various reasons it would be inconvenient in my code to generate an absolute URL. I can do it if necessary but I would prefer to see proof (e.g. specification, or Mozilla bug report) that it's necessary before making my code messy What do you think? Does anyone know of any evidence that the URL should be absolute? Or am I doing something else wrong? It seems such a simple/obvious tag, where nothing could go wrong, but I can't get it to work.

How to avoid chaotic ASP.NET web application deployment?

- by emzero

Ok, so here's the thing. I'm developing an existing (it started being an ASP classic app, so you can imagine :P) web application under ASP.NET 4.0 and SQLServer 2005. We are 4 developers using local instances of SQL Server 2005 Express, having the source-code and the Visual Studio database project This webapp has several "universes" (that's how we call it). Every universe has its own database (currently on the same server) but they all share the same schema (tables, sprocs, etc) and the same source/site code. So manually deploying is really annoying, because I have to deploy the source code and then run the sql scripts manually on each database. I know that manual deploying can cause problems, so I'm looking for a way of automating it. We've recently created a Visual Studio Database Project to manage the schema and generate the diff-schema scripts with different targets. I don't have idea how to put the pieces together I would like to: Have a way to make a "sync" deploy to a target server (thanksfully I have full RDC access to the servers so I can install things if required). With "sync" deploy I mean that I don't want to fully deploy the whole application, because it has lots of files and I just want to deploy those new or changed. Generate diff-sql update scripts for every database target and combine it to just 1 script. For this I should have some list of the databases names somewhere. Copy the site files and executing the generated sql script in an easy and automated way. I've read about MSBuild, MS WebDeploy, NAnt, etc. But I don't really know where to start and I really want to get rid of this manual deploy. If there is a better and easier way of doing it than what I enumerated, I'll be pleased to read your option. I know this is not a very specific question but I've googled a lot about it and it seems I cannot figure out how to do it. I've never used any automation tool to deploy. Any help will be really appreciated, Thank you all, Regards

Skip makefile dependency generation for certain targets (e.g. `clean`)

- by Shtééf

I have several C and C++ projects that all follow a basic structure I've been using for a while now. My source files go in src/*.c, intermediate files in obj/*.[do], and the actual executable in the top level directory. My makefiles follow roughly this template: # The final executable TARGET := something # Source files (without src/) INPUTS := foo.c bar.c baz.c # OBJECTS will contain: obj/foo.o obj/bar.o obj/baz.o OBJECTS := $(INPUTS:%.cpp=obj/%.o) # DEPFILES will contain: obj/foo.d obj/bar.d obj/baz.d DEPFILES := $(OBJECTS:%.o=%.d) all: $(TARGET) obj/%.o: src/%.cpp $(CC) $(CFLAGS) -c -o $@ $< obj/%.d: src/%.cpp $(CC) $(CFLAGS) -M -MF $@ -MT $(@:%.d=%.o) $< $(TARGET): $(OBJECTS) $(LD) $(LDFLAGS) -o $@ $(OBJECTS) .PHONY: clean clean: -rm -f $(OBJECTS) $(DEPFILES) $(RPOFILES) $(TARGET) -include $(DEPFILES) Now I'm at the point where I'm packaging this for a Debian system. I'm using debuild to build the Debian source package, and pbuilder to build the binary package. The debuild step only has to execute the clean target, but even this causes the dependency files to be generated and included. In short, my question is really: Can I somehow prevent make from generating dependencies when all I want is to run the clean target?

Industry-style practices for increasing productivity in a small scientific environment

- by drachenfels

Hi, I work in a small, independent scientific lab in a university in the United States, and it has come to my notice that, compared with a lot of practices that are ostensibly followed in the industry, like daily checkout into a version control system, use of a single IDE/editor for all languages (like emacs), etc, we follow rather shoddy programming practices. So, I was thinking of getting together all my programs, scripts, etc, and building a streamlined environment to increase productivity. I'd like suggestions from people on Stack Overflow for the same. Here is my primary plan.: I use MATLAB, C and Python scripts, and I'd like to edit, compile them from a single editor, and ensure correct version control. (questions/things for which I'd like suggestions are in italics) 1] Install Cygwin, and get it to work well with Windows so I can use git or a similar version control system (is there a DVCS which can work directly from the windows CLI, so I can skip the Cygwin step?). 2] Set up emacs to work with C, Python, and MATLAB files, so I can edit and compile all three at once from a single editor (say, emacs) (I'm not very familiar with the emacs menu, but is there a way to set the path to the compiler for certain languages? I know I can Google this, but emacs documentation has proved very hard for me to read so far, so I'd appreciate it if someone told me in simple language) 3] Start checking in code at the end of each day or half-day so as to maintain a proper path of progress of my code (two questions), can you checkout files directly from emacs? is there a way to checkout LabVIEW files into a DVCS like git? Lastly, I'd like to apologize for the rather vague nature of the question, and hope I shall learn to ask better questions over time. I'd appreciate it if people gave their suggestions, though, and point to any resources which may help me learn.

Parsing/Tokenizing a String Containing a SQL Command

- by Alan Storm

Are there any open source libraries (any language, python/PHP preferred) that will tokenize/parse an ANSI SQL string into its various components? That is, if I had the following string SELECT a.foo, b.baz, a.bar FROM TABLE_A a LEFT JOIN TABLE_B b ON a.id = b.id WHERE baz = 'snafu'; I'd get back a data structure/object something like //fake PHPish $results['select-columns'] = Array[a.foo,b.baz,a.bar]; $results['tables'] = Array[TABLE_A,TABLE_B]; $results['table-aliases'] = Array[a=TABLE_A, b=TABLE_B]; //etc... Restated, I'm looking for the code in a database package that teases the SQL command apart so that the engine knows what to do with it. Searching the internet turns up a lot of results on how to parse a string WITH SQL. That's not what I want. I realize I could glop through an open source database's code to find what I want, but I was hoping for something a little more ready made, (although if you know where in the MySQL, PostgreSQL, SQLite source to look, feel free to pass it along) Thanks!

target-action uicontrolevents

- by Fabrizio Farinelli

I must be missing something obvious here but ... UIControl has a method - (void)addTarget:(id)target action:(SEL)action forControlEvents: (UIControlEvents)controlEvents which lets you add an action to be called when any of the given controlEvents occur. ControlEvents are a bitmask of events which tell you if a touch went down, or up inside, or was dragged etc., there's about 16 of them, you or them together and get called when any of them occur. The selector can have one of the following signatures - (void)action - (void)action:(id)sender - (void)action:(id)sender forEvent:(UIEvent *) none of those tell you what the control event bitmask was. The UIEvent is something slightly different, it's related to the actual touch event and doesn't (I think) contain the UIControlEvent. The sender (UIControl) doesn't have a way to find the control events either. I'd like to have one method which deals with a number of control events as I have some common code regardless of which event or events happened but I still need to know what the UIControlEvents were for some specific processing. Am I missing a way to find out what UIControlEvents were used when the action was called or do I really have to separate my code into -(void)actionWithUIControlEventX; -(void)actionWithUIControlEventY;

Binding data to the custom DataGridView

- by Jatin Chaturvedi

All, I have a customized DataGridView where I have implemented extra functionality and bounded datasource in the same custom DataGridView (Using C# and .NET). Now, I could able to use it properly by placing it on a panel control. I have added label as button on panel control to display data from datasource on to datagrid and create a binding source. Another Label which act as a button is used to update data from grid to databse. Issue: I pressed show label to display data in a dsatagridview. Modified the grid cell value and immediately pressed update label which is on same panel control. I observed that, the cursor is still in the grid cell when I press Save button. While saving, the cell value is null even though I have entered something in the presentation layer. My expected behaviour is to get the modified value while saving. Special Case: After typing something in the grid cell, if I click on somewhere else like the row below where I entered something, before I click on Save button, it is working fine. (Here, mainly I tried to remove the focus from the currently modified cell) Is there any way to bind sources before I click on save button? Please suggest me. Please feel free to ask me if you need any information. I have also seen same kind of problem on this forum, but unfortunately the author got the answer and didnt post it back. here is that URL: http://social.msdn.microsoft.com/Forums/en/winformsdesigner/thread/54dcc87a-adc2-4965-b306-9aa9e79c2946 Please help me.

Factory Pattern: Determining concrete factory class instantiation?

- by Chris

I'm trying to learn patterns and I'm stuck on determining how or where a Factory Pattern determines what class to instanciate. If I have a Application that calls the factory and sends it, say, an xml config file to determine what type of action to take, where does that logic for interpreting the config file happen? THE FACTORY using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace myNamespace { public abstract class SourceFactory { abstract public UploadSource getUploadSource(); } public class TextSourceFactory : SourceFactory { public override UploadSource getUploadSource() { return new TextUploadSource(); } } public class XmlSourceFacotry : SourceFactory { public override UploadSource getUploadSource() { return new XmlUploadSource(); } } public class SqlSourceFactory : SourceFactory { public override UploadSource getUploadSource() { return new SqlUploadSource(); } } } THE CLASSES using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace myNamespace { public abstract class UploadSource { abstract public void Execute(); } public class TextUploadSource : UploadSource { public override void Execute() { Console.WriteLine("You executed a text upload source"); } } public class XmlUploadSource : UploadSource { public override void Execute() { Console.WriteLine("You executed an XML upload source"); } } public class SqlUploadSource : UploadSource { public override void Execute() { Console.WriteLine("You executed a SQL upload source"); } } }

Creating a DataTable by filtering another DataTable

- by Jeff Dege

I'm working on a system that currently has a fairly complicated function that returns a DataTable, which it then binds to a GUI control on a ASP.NET WebForm. My problem is that I need to filter the data returned - some of the data that is being returned should not be displayed to the user. I'm aware of DataTable.select(), but that's not really what I need. First, it returns an array of DataRows, and I need a DataTable, so I can databind it to the GUI control. But more importantly, the filtering I need to do isn't something that can be easily put into a simple expression. I have an array of the elements which I do not want displayed, and I need to compare each element from the DataTable against that array. What I could do, of course, is to create a new DataTable, reading everything out of the original, adding to the new what is appropriate, then databinding the new to the GUI control. But that just seems wrong, somehow. In this case, the number of elements in the original DataTable aren't likely to be enough that copying them all in memory is going to cause too much trouble, but I'm wondering if there is another way. Does the .NET DataTable have functionality that would allow me to filter via a callback function?

Controls added in the designer are null during Page_Load

- by mwright

All of the names below are generic and not the actual names used. I have a custom UserControl with a Panel that contains a a couple Labels, both .aspx controls. .aspx: <asp:Panel runat="server"> <asp:Label ID="label1" runat="server"> </asp:Label> </asp:Panel> <asp:Panel runat="server"> <asp:Label ID="label2" runat="server"> </asp:Label> </asp:Panel> Codebehind: private readonly Object object; protected void Page_Load(object sender, EventArgs e) { // These are the lines that are failing // label1 and label2 are null label1.Text = object.Value1; label2.Text = object.Value2; } public ObjectRow(Object objectToDisplay) { object = objectToDisplay; } On another page, in the code behind, I create a new instance of the custom user control. protected void Page_Load(object sender, EventArgs e) { CustomControl control = new CustomControl(object); } The user control takes the parameter and attempts to set the labels based off of the object passed in. The labels that it tries to assign the values to are however, null. Is this an ASP.net lifecycle issue that I'm not understanding? My understanding based on the Microsoft ASP.net lifecycle page was that page controls were available after the Page_Initialization. What is the proper way to do this? Is there a better way?

silverlight 3: long running wcf call triggers 401.1 (access denied)

- by sympatric greg

I have a wcf service consumed by a silverlight 3 control. The Silverlight client uses a basicHttpBindinging that is constructed at runtime from the control's initialization parameters like this: public static T GetServiceClient<T>(string serviceURL) { BasicHttpBinding binding = new BasicHttpBinding(Application.Current.Host.Source.Scheme.Equals("https", StringComparison.InvariantCultureIgnoreCase) ? BasicHttpSecurityMode.Transport : BasicHttpSecurityMode.None); binding.MaxReceivedMessageSize = int.MaxValue; binding.MaxBufferSize = int.MaxValue; binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly; return (T)Activator.CreateInstance(typeof(T), new object[] { binding, new EndpointAddress(serviceURL)}); } The Service implements windows security. Calls were returning as expected until the result set increased to several thousand rows at which time HTTP 401.1 errors were received. The Service's HttpBinding defines closeTime, openTimeout, receiveTimeout and sendTimeOut of 10 minutes. If I limit the size of the resultset the call suceeds. Additional Observations from Fiddler: When Method2 is modified to return a smaller resultset (and avoid the problem), control initialization consists of 4 calls: Service1/Method1 -- result:401 Service1/Method1 -- result:401 (this time header includes element "Authorization: Negotiate TlRMTV..." Service1/Method1 -- result:200 Service1/Method2 -- result:200 (1.25 seconds) When Method2 is configured to return the larger resultset we get: Service1/Method1 -- result:401 Service1/Method1 -- result:401 (this time header includes element "Authorization: Negotiate TlRMTV..." Service1/Method1 -- result:200 Service1/Method2 -- result:401.1 (7.5 seconds) Service1/Method2 -- result:401.1 (15ms) Service1/Method2 -- result:401.1 (7.5 seconds)

rails HABTM versus view (formtastic)

- by VP

I have two models: The model NetworkObject try to describe "hosts". I want to have a rule with source and destination, so i'm trying to use both objects from the same class since it dont makes sense to create two different classes. class NetworkObject < ActiveRecord::Base attr_accessible :ip, :netmask, :name has_many :statements has_many :rules, :through =>:statements end class Rule < ActiveRecord::Base attr_accessible :active, :destination_ids, :source_ids has_many :statements has_many :sources, :through=> :statements, :source=> :network_object has_many :destinations, :through => :statements, :source=> :network_object end To build the HABTM i did choose the Model JOIN. so in this case i created a model named Statement with: class Statement < ActiveRecord::Base attr_accessible :source_id, :rule_id, :destination_id belongs_to :network_object, :foreign_key => :source_id belongs_to :network_object, :foreign_key => :destination_id belongs_to :rule end The problem is: is right to add two belongs_to to the same class using different foreign_keys? I tried all combinations like: belongs_to :sources, :class_name => :network_object, :foreign_key => :source_id but no success.. anything that i am doing wrong?

Automatic web form testing/filling

- by Polatrite

I recently became lead on getting an inordinate amount of testing done in a very short period of time. We have many different web forms, using custom (Telerik) controls that need to be tested for proper data validation and sensible handling of the data. Some of the forms are several pages long with 30-80 different controls for data entry. I am looking for a software solution (that is free) that would allow me to automate the process of filling in these forms by designing a script, or using a UI. The other requirement is that I can't use any browsers but IE6 (terrible, I know). I have previously used AutoHotkey to great success for automatic Windows form testing, since Autohotkey's API allows you to directly reference controls on the Windows form. However Autohotkey does not have similar support for web forms (everything is just one big "InternetExplorer" control). While I would prefer that I could script some variance in the data to help serialize each test, it's not necessary, as I could go back through and manually edit a field or two (plus "break" whatever control I'm currently testing) to serialize each test. If you've ever seen Spawner: http://forge.mysql.com/projects/project.php?id=214 It's almost exactly the sort of thing I'm looking for (Spawner generates dummy SQL data, as opposed to dummy webform data) - but I won't be picky, I've got a really short deadline to meet and had this thrust in my lap just today. ;) Edit1: One of the challenges of just using Autohotkey to simulate keyboard input (tabbing through controls) is that some controls don't currently have tab index (bug), and some controls cause a page reload after modification, resulting in inconsistent control focus (tabbing screwed up). Our application makes heavy use of page reloads to populate fields (select a location, it auto-populates a city, for example).

Hello friends, I am trying to implement 'scrollview' effect in 'Tabbar' which has 'TabItems'. I found that the good example is from 'facebook' open source 'TTCatlog' project 'Tabs' section. So i included all the source from it to my project and trying to build it. I have followed the following links to go ahead on this: http://stackoverflow.com/questions/822792/how-to-create-a-horizontal-scrolling-view-on-iphone source: http://github.com/facebook/three20/tree/master/samples/ My calling code is like below: _tabBar1 = [[TTTabStrip alloc] initWithFrame:CGRectMake(10, 68, 300, 28)]; _tabBar1.tabItems = [NSArray arrayWithObjects: [[[TTTabItem alloc] initWithTitle:@"Item 1"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 2"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 3"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 4"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 5"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 6"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 7"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 8"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 9"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 10"] autorelease], nil]; [self.navigationController.view addSubview:_tabBar1]; My project folder as like below: ..../iphone/MyProgram/MyProgram.xcodeproj ..../iphone/Three20/src/Three20.... In my project settings for header search path, I have ../Three20/src But when i try to build it, it throws the following error: "objc_class_name_TTTabStrip symbol not found" "objc_class_name_TTTabItem symbol not found" I see there, all these files (.h and .m) are availbale there. Could someone please help what's wrong there and how do i get rid of this issue and continue working with it?

Create Folders from text file and place dummy file in them using a CustomAction

- by Birkoff

I want my msi installer to generate a set of folders in a particular location and put a dummy file in each directory. Currently I have the following CustomActions: <CustomAction Id="SMC_SetPathToCmd" Property="Cmd" Value="[SystemFolder]cmd.exe"/> <CustomAction Id="SMC_GenerateMovieFolders" Property="Cmd" ExeCommand="for /f "tokens=* delims= " %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (echo %a)" /> <CustomAction Id="SMC_CopyDummyMedia" Property="Cmd" ExeCommand="for /f "tokens=* delims= " %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (copy [MBSAMPLECOLLECTIONS]dummy.avi "%a"\"%a".avi)" /> These are called in the InstallExecuteSequence: <Custom Action="SMC_SetPathToCmd" After="InstallFinalize"/> <Custom Action="SMC_GenerateMovieFolders" After="SMC_SetPathToCmd"/> <Custom Action="SMC_CopyDummyMedia" After="SMC_GenerateMovieFolders"/> The custom actions seem to start, but only a blank command prompt window is shown and the directories are not generated. The files needed for the customaction are copied to the correct directory: <Directory Id="WIX_DIR_COMMON_VIDEO"> <Directory Id="MBSAMPLECOLLECTIONS" Name="MB Sample Collections" /> </Directory> <DirectoryRef Id="MBSAMPLECOLLECTIONS"> <Component Id="SampleCollections" Guid="C481566D-4CA8-4b10-B08D-EF29ACDC10B5" DiskId="1"> <File Id="movies.txt" Name="movies.txt" Source="SampleCollections\movies.txt" Checksum="no" /> <File Id="series.txt" Name="series.txt" Source="SampleCollections\series.txt" Checksum="no" /> <File Id="dummy.avi" Name="dummy.avi" Source="SampleCollections\dummy.avi" Checksum="no" /> </Component> </DirectoryRef> What's wrong with these Custom Actions or is there a simpler way to do this?

WPF: Selecting the Target of an Animation

- by Phil Sandler

I am trying to create a simple (I think) animation effect based on a property change in my ViewModel. I would like the target to be a specific textblock in the control template of a custom control, which inherits from Window. From the article examples I've seen, a DataTrigger is the easiest way to accomplish this. It appears that Window.Triggers doesn't support DataTriggers, which led me to try to apply the trigger in the style. The problem I am currently having is that I can't seem to target the TextBlock (or any other child control)--what happens is which the code below is that the animation is applied to the background of the whole window. If I leave off StoryBoard.Target completely, the effect is exactly the same. Is this the right approach with the wrong syntax, or is there an easier way to accomplish this? <Style x:Key="MyWindowStyle" TargetType="{x:Type Window}"> <Setter Property="Template" Value="{StaticResource MyWindowTemplate}"/> <Style.Triggers> <DataTrigger Binding="{Binding ChangeOccurred}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard BeginTime="00:00:00" Duration="0:0:2" Storyboard.Target="{Binding RelativeSource={RelativeSource AncestorType=TextBlock}}" Storyboard.TargetProperty="(Background).(SolidColorBrush.Color)"> <ColorAnimation FillBehavior="Stop" From="Black" To="Red" Duration="0:0:0.5" AutoReverse="True"/> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger> </Style.Triggers> </Style>

MS Dynamics CRM trapping .NET error before I can handle it

- by clifgriffin

This is a fun one. I have written a custom search page that provides faster, more user friendly searches than the default Contacts view and also allows searching of Leads and Contacts simultaneously. It uses GridViews bound to SqlDataSources that query filtered views. I'm sure someone will complain that I'm not using the web services for this, but this is just the design decision we made. These GridViews live in UpdatePanels to enable very slick AJAX updates upon search. It's all working great. Nearly ready to be deployed, except for one thing: Some long running searches are triggering an uncatchable SQL timeout exception. [SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.] at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlDataReader.ConsumeMetaData() at System.Data.SqlClient.SqlDataReader.get_MetaData() at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method) at System.Data.SqlClient.SqlCommand.ExecuteDbDataReader(CommandBehavior behavior) at System.Data.Common.DbCommand.System.Data.IDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable) at System.Web.UI.WebControls.SqlDataSourceView.ExecuteSelect(DataSourceSelectArguments arguments) at System.Web.UI.DataSourceView.Select(DataSourceSelectArguments arguments, DataSourceViewSelectCallback callback) at System.Web.UI.WebControls.DataBoundControl.PerformSelect() at System.Web.UI.WebControls.BaseDataBoundControl.DataBind() at System.Web.UI.WebControls.GridView.DataBind() at System.Web.UI.WebControls.BaseDataBoundControl.EnsureDataBound() at System.Web.UI.WebControls.CompositeDataBoundControl.CreateChildControls() at System.Web.UI.Control.EnsureChildControls() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) I found that CRM is doing a server.transfer to capture this error because my UpdatePanels started throwing JavaSript errors when this error would occur. I was only able to get the full error message by using the JavaScript debugger in IE. Having found this error, I thought the solution would be simple. I just needed to wrap my databind calls in try/catch blocks to capture any errors. Unfortunately it seems CRM's IIS configuration has the magic ability to capture this error before it ever gets back to my code. Using the debugger I never see it. It never gets to my catch blocks, but it's clearly happening in the SQL Data Source which is clearly (by the stack trace) being triggered by my GridView bind. Any ideas on this?

Load image dynamically on Silverlight

- by FelixMM

I have a Silverlight app that has to load an image dynamically, depending on the image name. The approach that im taking right now is passing the image name by query string to the page and passing that as a param to the Silverlight objet tag This is the query string passed Response.Redirect("Build.aspx?img=" + this.PictureUploader.PostedFile.FileName; And I try to pass it to Silverlight like this: <object id="SilverlightObject" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="Silverlight/iMapsSL.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40624.0" /> <param name="autoUpgrade" value="true" /> <param name="image" value="<%# Request.QueryString["img"] %>" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe> in the last param tag with name=image value= Requerst.QueryString I catch the image inside the Silverlight app like this private void Application_Startup(object sender, StartupEventArgs e) { string pictureName = ""; if (e.InitParams != null && e.InitParams.Count > 0) { pictureName = e.InitParams["image"]; this.RootVisual = new MainPage(pictureName); } else { this.RootVisual = new MainPage(); } } And when MainPage starts, I set the image source of the Image control like this this.Image.Source = new BitmapImage(new Uri(pictureName, UriKind.RelativeOrAbsolute)); But Silverlight loads without an image, any help someone?

Div click and AUTOCOMPLETE password dialog problem

- by ticky

And what if you want to autocomplete passwords? I am using similar thing here... I am using Div (id=loginButton) and it has some image - I don't want button control in MVC application (), neither image button. I have hidden input control which is hidden button actually (id=submit_btn). So, on div's (id=loginButton) click, I want to call hidden input control (id=submit_btn) and it's submit action. HTML: <div id="loginButton" > </div> <input type="submit" style="display:none" name="submit" id="submit_btn" /> And JQuery: $(document).ready(function() { $('#loginButton').click(function() { $('#LoginForm').submit(); }); $("form[action$='HandleLoginForm']").submit(function() { Login(); return false; }); return false; }); Function Login() is working with Ajax, without downloading file dialog, but I need also auto complete passwords dialog. function Login() { var urlData = $("#LoginForm").serialize(); if (returnUrl != "") { urlData = $("#LoginForm").serialize() + "&returnUrl=" + returnUrl; } $.ajax({ url: $("#LoginForm").attr("action"), type: "POST", data: urlData, dataType: "json", success: function(result) { if (result.Content != null) { if (result.Valid) { window.location = result.Content.toString(); } else { document.body.innerHTML = result.Content.toString(); } } } }); return false; } It is easy when you use only <input type="submit"> instead of DIV. Form knows that it is for auto completing passwords, but if I use div and force hidden button click like in the code from below, it doesn't show autocomplete password dialog. $('#submit_btn').click(); It will not work. User is logged in, but no reminding for browser to store password. I need this.

Avoid the collapsing effect on TreeView after updating data

- by Manolete

I have a TreeView used to display events. It works great, however every time new events are coming in and populating the tree collapse the tree again to the original position. That is very annoying when the refresh time is less than 1 second and it does not allow the user to interact with the items of the tree. Is there any way to avoid this behaviour? <TreeView Margin="1" BorderThickness="0" Name="eventsTree" ItemsSource="{Binding EventAlertContainers}" Background="#00000000" ScrollViewer.VerticalScrollBarVisibility="Auto" FontSize="14" VirtualizingStackPanel.IsVirtualizing="True"> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type C:EventAlertContainer}" ItemsSource="{Binding EventAlerts}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="3,0" Source="Resources\Process_info_32.png" /> <TextBlock FontWeight="Bold" FontSize="16" Text="{Binding Description}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:EventAlert}" ItemsSource="{Binding Events}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\clock2_32.jpg" /> <TextBlock FontWeight="DemiBold" FontSize="14" Text="{Binding Name}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:Event}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\Task_32.png" /> <StackPanel Orientation="Vertical"> <TextBlock FontSize="12" Text="{Binding Name}" /> </StackPanel> </StackPanel> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView>

So my question is about: Is my decision wise to go for C# and .Net Framework route after working for sometime as an PHP Developer ? What are the good resources which I can refer and learn from to get knowledge on C# and .NET Framework ? How should I go about learning on C# and .NET Framework ?

Disable Painting of the VScrollbar in a System.Windows.Forms.RichTextBox

- by SchlaWiener

I have a custom control inherited from RichTextBox. This control has the ability to "disable" rich text editing. I achive this by just setting the Rtf property to the text property during the TextChanged event. this is how my code looks like: private bool lockTextChanged; void RichTextBox_TextChanged(object sender, EventArgs e) { // prevent StackOverflowException if (lockTextChanged) return; // remember current position int rtbstart = rtb.SelectionStart; int len = rtb.SelectionLength; // prevent painting rtb.SuspendLayout(); // set the text property to remove the entire formatting. lockTextChanged = true; rtb.Text = rtb.Text; rtb.Select(rtbstart, len); lockTextChanged = false; rtb.ResumeLayout(true); } That worked well. However in a large text with like 200 lines the controls jitters (you see the first lines of text for the wink). To prevent that from happening I filter the WM_PAINT between SuspendLayout() and ResumeLayout() private bool layoutSuspended; public new void SuspendLayout() { layoutSuspended = true; base.SuspendLayout(); } public new void ResumeLayout() { layoutSuspended = false; base.ResumeLayout(); } public new void ResumeLayout(bool performLayout) { layoutSuspended = false; base.ResumeLayout(performLayout); } private const int WM_PAINT = 0x000F; protected override void WndProc(ref System.Windows.Forms.Message m) { if (!(m.Msg == WM_PAINT && layoutSuspended)) base.WndProc(ref m); } that did the trick, the RichTextBox isn't jittering anymoe. That's what I wanted to achive, except one thing: The scrollbar is still jittering everytime I type text to my control. Now my question: Does anyone have a clue for me how to prevent the scrollbar from redrawing during Suspend/Resume Layout?

Switching AM/PM in ASP.NET AJAX MaskedEdit localization

- by Greg

The sample page for the MaskedEdit says "Tip: Type 'A' or 'P' to switch AM/PM". Are these keys hardcoded? Does the control automatically change itself for cultures that use 12-hour designators that don't start with A or P? Or is just broken for those? example: Arabic (Saudi Arabia) - AM: ? Arabic (Saudi Arabia) - PM: ? Chinese (Taiwan) - AM: ?? Chinese (Taiwan) - PM: ?? Greek (Greece) - AM: pµ Greek (Greece) - PM: µµ Korean (Korea) - AM: ?? Korean (Korea) - PM: ?? Albanian (Albania) - AM: PD Albanian (Albania) - PM: MD Persian (Iran) - AM: ?.? Persian (Iran) - PM: ?.? Vietnamese (Vietnam) - AM: SA Vietnamese (Vietnam) - PM: CH Afrikaans (South Africa) - PM: nm Punjabi (India) - AM: ????? Punjabi (India) - PM: ??? Syriac (Syria) - AM: ?.? Syriac (Syria) - PM: ?.? If this control doesn't handle this situation, does anyone know of a control that does?

Do the new NoPIA and Type Equivalence features in C#/.NET 4.0 mean Microsoft.mshtml.dll is no longer

- by jpierson

I'm maintaining a WPF based application which contains a WinForms based WebBrowser control that based on the IE web browser control. When we deploy, we have had to also supply Microsoft.mshtml.dll and do some custom configuration stuff for our ClickOnce publishing process as well in order to get things to work. I'm curious that with the new NoPIA and Type Equivalence features and dynamic type capabilities in C# 4.0 can we expect that if we upgrade that we can remove the dependencies on the Microsoft.mshtml.dll assembly? If so this will not only reduce the size of our deployment quite a bit but will also simplify our publishing process as well. It is my understanding that we should be able embed the types that normally get automatically generated into extra assemblies for COM types such as the MapPoint Control by Visual Studio. I don't know if this also applies to the Microsoft.mshtml.dll or even how it is done even in the most simple of cases. If somebody could provide an explanation about what the practical impact of these new features are on a project that relies on COM interop and especially the Microsoft.mshtml.dll assembly it would be of great help to me.
