Yes I could google it, but I am looking for some insight from some people whp handle the end of the software I would as a programmer. The tool has to run using IIS as the webserver. What are some of the best features of your suggestion?

  • How to quickly acquire and process real time screen output

    - by Akusete
    I am trying to write a program to play a full screen PC game for fun (as an experiment in Computer Vision and Artificial Intelligence). For this experiment I am assuming the game has no underlying API for AI players (nor is the source available) so I intend to process the visual information rendered by the game on the screen. The game runs in full screen mode on a win32 system (direct-X I assume). Currently I am using the win32 functions #include <windows.h> #include <cvaux.h> class Screen { public: HWND windowHandle; HDC windowContext; HBITMAP buffer; HDC bufferContext; CvSize size; uchar* bytes; int channels; Screen () { windowHandle = GetDesktopWindow(); windowContext = GetWindowDC (windowHandle); size = cvSize (GetDeviceCaps (windowContext, HORZRES), GetDeviceCaps (windowContext, VERTRES)); buffer = CreateCompatibleBitmap (windowContext, size.width, size.height); bufferContext = CreateCompatibleDC (windowContext); SelectObject (bufferContext, buffer); channels = 4; bytes = new uchar[size.width * size.height * channels]; } ~Screen () { ReleaseDC(windowHandle, windowContext); DeleteDC(bufferContext); DeleteObject(buffer); delete[] bytes; } void CaptureScreen (IplImage* img) { BitBlt(bufferContext, 0, 0, size.width, size.height, windowContext, 0, 0, SRCCOPY); int n = size.width * size.height; int imgChannels = img->nChannels; GetBitmapBits (buffer, n * channels, bytes); uchar* src = bytes; uchar* dest = (uchar*) img->imageData; uchar* end = dest + n * imgChannels; while (dest < end) { dest[0] = src[0]; dest[1] = src[1]; dest[2] = src[2]; dest += imgChannels; src += channels; } } The rate at which I can process frames using this approach is much to slow. Is there a better way to acquire screen frames?

  • Can I return values to PHP from an anonymous PL/SQL block?

    - by RenderIn
    I'm using PHP and OCI8 to execute anonymous Oracle PL/SQL blocks of code. Is there any way for me to bind a variable and get its output upon completion of the block, just as I can when I call stored procedures in a similar way? $SQL = "declare something varchar2 := 'I want this returned'; begin --How can I return the value of 'something' into a bound PHP variable? end;";

  • Facebook Developer ToolKit: How should I construct this app?

    - by j0nscalet
    I have created a simple desktop application that I want to use to post status updates for the users of my app. Here's the kicker though that I am having trouble figuring out, the desktop application runs as part of a batch process every night, in which I update the status of certain users. I use the following code to accomplish this: (comes directly from the FDK samples) public FriendViewer() { InitializeComponent(); facebookService1.ApplicationKey = "Key"; facebookService1.Secret = "Secret"; facebookService1.SessionKey = "Session key"; facebookService1.IsDesktopApplication = true; } private void TestService_Load(object sender, EventArgs e) { try { if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.status_update)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.status_update); if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.offline_access)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.offline_access); long uid = facebookService1.users.getLoggedInUser(); facebook.Schema.user user = facebookService1.users.getInfo(uid); facebookService1.users.setStatus("Facebook Syndicator rules!"); MessageBox.Show(String.Format("Status set for {0} {1}", user.first_name, user.last_name)); } catch (Exception ex) { MessageBox.Show(ex.Message); Close(); } } My user's day to day activity is done a website front end. Since I dont have any user interaction in a nightly batch process, I cannot use the ConnectToFaceBook method on the FaceBookService to obtain a sessionKey for the user. Ideally I would like to prompt for authorization and extended permissions for my desktop app when a user logins into the web front end then save the sessionKey and uid in the database. At night when my process runs, I would reference the sessionKey and uid in order and update the user's status. I am finding myself fumbling between whether or not my app should be a web or desktop app. Having both a web and desktop app would be confusing to my users, because they would have to grant/manage permissions for both apps. And I looking at this the wrong way? Any help would be greatly appreciated! Thanks.

  • For a .NET winforms datagridview I would like a combobox column to have a different set of values for each row.

    - by Seth Spearman
    Hello, I have a DataGridView that I am binding to a POCO. I have the databinding working fine. However, I have added a combobox column that I want to be different for each row. Specifically, I have a grid of purchased items, some of which have sizes (like Adult XL, Adult L) and other items are not sized (like Car Magnet.) So essentially what I want to change is the DATA SOURCE for a combobox column in the data grid. Can that be done? What event can I hook into that would allow me to change properties of certain columns FOR EACH ROW? An acceptable alternative is to change a property when the user clicks or tabs into the row. What event is that? Seth EDIT I need more help with this question. With Triduses help I am SO close but I need a bit more information. First, per the question, is the CellFormatting event really the best/only event for changing the DataSource for a combo box column. I ask because I am doing something rather resource/data intensive, not merely formatting the cell. Second, the cellformatting event is being called just by having the mouse hover over the cell. I tried to set the FormattingApplied property inside my if-block and then I check for it in the if- test but that is returning a weird error message. My ideal situation is that I would apply change the data source for the combo box once for each row and then be done with it. Finally, in order to set the data source of the combobox colunm I have to be able to cast the Cell inside my if block to a type of DataGridViewComboBoxColumn so that I can fill it with rows or set the datasource or something. Here is the code I have right now. Private Sub ProductsDataGrid_CellFormatting(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles ProductsDataGrid.CellFormatting If e.ColumnIndex = ProductsDataGrid.Columns("SizeDGColumn").Index Then ' AndAlso Not e.FormattingApplied Then Dim product As LeagueOrderProductInfo = DirectCast(ProductsDataGrid.Rows(e.RowIndex).DataBoundItem, LeagueOrderProductInfo) Dim sizes As LeagueOrderProductSizeList = product.ProductSizes sizes.RemoveSizeFromList(_parentOrderDetail.SizeID) 'WHAT DO I DO HERE TO FILL THE COMBOBOX COLUMN WITH THE sizes collection. End If End Sub Please help. I am completely stuck and this task item should have taken an hour and I am 4+ hours in now. BTW, I am also open to resolving this by taking a completely different direction with it (as long as I can be done quickly.) Seth

  • Print Preview Control used in a custom Print Preview Dialog.

    - by Kildareflare
    I have successfully implemented printing and print preview for my app using the PrintDocument, PrintDialog and PrintPreviewDialog classes of .NET. However my app uses a toolkit to improve the appearance of the standard .NET controls. There are versions of most .NET controls in the toolkit, but none for the Print controls. Therefore to ensure that the appearance of these controls matches the rest of the app I am creating a custom PrintPreviewDialog based on a toolkit form and embedding a .NET PrintPrewviewControl in it. My problem is that the PrintPreviewControl always shows "No pages to display". I had no trouble getting this to work using the .NET PrintPreviewDialog and cannot see what I am doing wrong. This is a .NET 2.0 PrintPreviewControl and so I know that I need to call InvalidatePreview() after assigning the PrintDocument. However it does not seem to matter where i place it, the PrintPage event handler never gets called... EDIT: I've just noticed that while the original PrintDocument m_printDocument shows a PrintPageHandler in its properties, the m_printPreviewControl.Document does not. Any ideas why it is being lost..? public class PrintEngine { ...rest of class... public PrintEngine() { m_printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage); } public void PrintPreview() { //ORIGINAL CODE USING .NET DIALOG WORK OK //PrintPreviewDialog dlg1 = new PrintPreviewDialog(); //dlg1.Document = m_printDoc; //PrepareImageForPrinting(); //dlg1.ShowDialog(); //CODE USING MY CUSTOM DIALOG DO NOT WORK? MyPrintPreviewDialog dlg2 = new MyPrintPreviewDialog(); dlg2.Document = m_printDoc; PrepareImageForPrinting(); //Creates the m_printImage List dlg2.ShowDialog(); } private void printDoc_PrintPage(object sender, PrintPageEventArgs e) { e.Graphics.DrawImage(m_printImages[m_currentPage], new Point(0, 0)); m_currentPage++; e.HasMorePages = m_currentPage < m_pagesHigh; } }//end PrintEngine class public class MyPrintPreviewDialog : KryptonForm { public PrintDocument Document { get { return m_printPreviewControl.Document; } set { m_printPreviewControl.Document = value; m_printPreviewControl.InvalidatePreview(); } } public MyPrintPreviewDialog() { InitializeComponent(); m_printPreviewControl = new PrintPreviewControl(); m_printPreviewControl.StartPage = 0; } private void MyPrintPreviewDialog_Load(object sender, EventArgs e) { m_printPreviewControl.Document.DefaultPageSettings = new PageSettings(); m_printPreviewControl.Document.PrinterSettings = new PrinterSettings(); m_printPreviewControl.InvalidatePreview(); } }//end MyPrintPreviewDialog class

  • How Do I Prevent Rails From Treating Updated Nested Attributes Differently From New Nested Attribute

    - by James
    I am using rails3 beta3 and couchdb via couchrest. I am not using active record. I want to add multiple "Sections" to a "Guide" and add and remove sections dynamically via a little javascript. I have looked at all the screencasts by Ryan Bates and they have helped immensely. The only difference is that I want to save all the sections as an array of sections instead of individual sections. Basically like this: "sections" => [{"title" => "Foo1", "content" => "Bar1"}, {"title" => "Foo2", "content" => "Bar2"}] So, basically I need the params hash to look like that when the form is submitted. When I create my form I am doing the following: <%= form_for @guide, :url => { :action => "create" } do |f| %> <%= render :partial => 'section', :collection => @guide.sections %> <%= f.submit "Save" %> <% end %> And my section partial looks like this: <%= fields_for "sections[]", section do |guide_section_form| %> <%= guide_section_form.text_field :section_title %> <%= guide_section_form.text_area :content, :rows => 3 %> <% end %> Ok, so when I create the guide with sections, it is working perfectly as I would like. The params hash is giving me a sections array just like I would want. The problem comes when I want edit guide/sections and save them again because rails is inserting the id of the guide in the id and name of each form field, which is screwing up the params hash on form submission. Just to be clear, here is the raw form output for a new resource: <input type="text" size="30" name="sections[][section_title]" id="sections__section_title"> <textarea rows="3" name="sections[][content]" id="sections__content" cols="40"></textarea> And here is what it looks like when editing an existing resource: <input type="text" value="Foo1" size="30" name="sections[cd2f2759895b5ae6cb7946def0b321f1][section_title]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_section_title"> <textarea rows="3" name="sections[cd2f2759895b5ae6cb7946def0b321f1][content]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_content" cols="40">Bar1</textarea> How do I force rails to always use the new resource behavior and not automatically add the id to the name and value. Do I have to create a custom form builder? Is there some other trick I can do to prevent rails from putting the id of the guide in there? I have tried a bunch of stuff and nothing is working. Thanks in advance!

  • SubSonic 2.x now supports TVP's - SqlDbType.Structure / DataTables for SQL Server 2008

    - by ElHaix
    For those interested, I have now modified the SubSonic 2.x code to recognize and support DataTable parameter types. You can read more about SQL Server 2008 features here: http://download.microsoft.com/download/4/9/0/4906f81b-eb1a-49c3-bb05-ff3bcbb5d5ae/SQL%20SERVER%202008-RDBMS/T-SQL%20Enhancements%20with%20SQL%20Server%202008%20-%20Praveen%20Srivatsav.pdf What this enhancement will now allow you to do is to create a partial StoredProcedures.cs class, with a method that overrides the stored procedure wrapper method. A bit about good form: My DAL has no direct table access, and my DB only has execute permissions for that user to my sprocs. As such, SubSonic only generates the AllStructs and StoredProcedures classes. The SPROC: ALTER PROCEDURE [dbo].[testInsertToTestTVP] @UserDetails TestTVP READONLY, @Result INT OUT AS BEGIN SET NOCOUNT ON; SET @Result = -1 --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] ON INSERT INTO [dbo].[tbl_TestTVP] ( [GroupInsertID], [FirstName], [LastName] ) SELECT [GroupInsertID], [FirstName], [LastName] FROM @UserDetails IF @@ROWCOUNT > 0 BEGIN SET @Result = 1 SELECT @Result RETURN @Result END --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] OFF END The TVP: CREATE TYPE [dbo].[TestTVP] AS TABLE( [GroupInsertID] [varchar](50) NOT NULL, [FirstName] [varchar](50) NOT NULL, [LastName] [varchar](50) NOT NULL ) GO The the auto gen tool runs, it creates the following erroneous method: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(string UserDetails, int? Result) { SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); sp.Command.AddParameter("@UserDetails", UserDetails, DbType.AnsiString, null, null); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } It sets UserDetails as type string. As it's good form to have two folders for a SubSonic DAL - Custom and Generated, I created a StoredProcedures.cs partial class in Custom that looks like this: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(DataTable dt, int? Result) { DataSet ds = new DataSet(); SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); // TODO: Modify the SubSonic code base in sp.Command.AddParameter to accept // a parameter type of System.Data.SqlDbType.Structured, as it currently only accepts // System.Data.DbType. //sp.Command.AddParameter("@UserDetails", dt, System.Data.SqlDbType.Structured null, null); sp.Command.AddParameter("@UserDetails", dt, SqlDbType.Structured); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } As you can see, the method signature now contains a DataTable, and with my modification to the SubSonic framework, this now works perfectly. I'm wondering if the SubSonic guys can modify the auto-gen to recognize a TVP in a sproc signature, as to avoid having to re-write the warpper? Does SubSonic 3.x support Structured data types? Also, I'm sure many will be interested in using this code, so where can I upload the new code? Thanks.

  • WEBrick::HTTPStatus::LengthRequired error when accessing create method in controller

    - by Chris Bisignani
    I have a very simple controller set up: class LibrariesController < ApplicationController ... def create @user.libraries << Library.new(params) @user.save render :json => "success!" end ... end Basically, whenever I try to access the create method of LibrariesController using HTTParty.post I get a WEBrick::HTTPStatus::LengthRequired error on the server.

  • How do I mock an object in this case? no obvious way to replace object with mock

    - by Tristan
    Hi there, Suppose I have this very simple method in Store's model: def geocode_address loc = Store.geocode(address) self.lat = loc.lat self.lng = loc.lng end If I want to write some test scripts that aren't affected by the geocoding service, which may be down, have limitations or depend on my internet connection, how do I mock out the geocoding service? If I could pass a geocoding object into the method, it would be easy, but I don't see how I could do it in this case. Thanks! Tristan

  • ItemsPanel vs Grid vs GridSplitter

    - by bitbonk
    I am currently trying to build a ControlTemplate for an ItemsControl that uses the Grid as its ItemsPanel where each item is stacked horizontally and delimited with a GridSplitter. The basic goal is to have a dynamic bindable ItemsControl where all items stack up in a row and where each item can be resized with a splitter. There are two things I can't wrap my head around: How is the GridSplitter supposed to end up automatically between each item? How do I set Grid.Column for each item.

  • How to get GWT 2.0 and Restlet 2.0 to play nice

    - by Holograham
    Hello, I am having trouble getting Restlet to play nice with GWT in the same project. I have been trying the examples from Restlets website to no avail I am using Eclipse, Maven2 plugin, GWT, and Restlet GWT. I have never used server side code in this GWT project before and I know there is some custom setup involved. I am deploying locally for the time being using the built in Jetty in GWT Hosted Mode. I can get my front end to display but my back end is not executing. I did add this to my web.xml file which is from the example (for the time being I am trying to drop the example into my project). <servlet> <servlet-name>adapter</servlet-name> <servlet-class>org.restlet.ext.gwt.GwtShellServletWrapper</servlet-class> <init-param> <param-name>org.restlet.application</param-name> <param-value>org.restlet.example.gwt.server.TestServerApplication</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>adapter</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> I did notice that my web.xml file is located separately from my war deployment directory. My project dir structure is setup as follows. Project Root src/main/java src/main/resources src/main/test JRE Maven Dependecies GWT SDK src main webapp WEB-INF web.xml target war <my project dir> WEB-INF lib pom.xml So there is no web.xml under my war files WEB-INF directory. I am new to this type of application so it is most likely a matter of me not understanding the directory structure and how my GWT project is compiling into these dirs. Any help is appreciated! If I need to provide any more info let me know. Thanks

  • RPXNow user mapping

    - by chelfers
    I am looking into solutions for providing multiple login methods to my site. I found rpxnow.com and they map user accounts from all the different networks. My question is how do they know that I am user1 on twitter and bigdude2 on facebook? I'm hoping it goes beyond email lookups. The end result I want is a unique user in my database no matter what account they sign in with, dupes are a no-no, but most likely inevitable I am guessing.

  • An existing connection was forcibly closed by the remote host

    - by George
    I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while, I get the subject error. The error happenes The error seems to occur in < 1 min, which is far less that the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server. It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Smit.Pipeline.Bo.localhost.WsSR.SaveOptions(String emailId, DataSet dsNeighborhood, DataSet dsOption, DataSet dsTaskApplications, DataSet dsCcUsers, DataSet dsDistinctUsers, DataSet dsReferencedApplications) in C:\My\Code\Pipeline2\Smit.Pipeline.Bo\Web References\localhost\Reference.vb:line 944 at Smit.Pipeline.Bo.Options.Save(TaskApplications updatedTaskApplications) in I've been looking a tons of postings on this error and it is surprising at how varied the circumstances which cause this error are. I've tried messing with Wireshark, but I am clueless how to use it. This application only has about 20 users at any one time and I am able to reproduce this error in the middle of the night when probably no one is using the app, so I don't think that the number of requests to the web server or to the database is high. It's probably one right now when I just got the error now. It seems to have to do everything with the amt of data being passed in either direction. This error is really chronic and killing me. Please help.

  • calling and killing a parent function with onmouseover and onmouseout events

    - by Zoolu
    I want to call the function upon the onmouseover="ParentFunction();" then kill it onmouseout="killParent();". Note: in my code the parent function is called initiate(); and the killer function is called reset(); which lies outside the parent function at the bottom of the script.

  • Linq to LLBLGen query problem

    - by Jeroen Breuer
    Hello, I've got a Stored Procedure and i'm trying to convert it to a Linq to LLBLGen query. The query in Linq to LLBGen works, but when I trace the query which is send to sql server it is far from perfect. This is the Stored Procedure: ALTER PROCEDURE [dbo].[spDIGI_GetAllUmbracoProducts] -- Add the parameters for the stored procedure. @searchText nvarchar(255), @startRowIndex int, @maximumRows int, @sortExpression nvarchar(255) AS BEGIN SET @startRowIndex = @startRowIndex + 1 SET @searchText = '%' + @searchText + '%' -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- This is the query which will fetch all the UmbracoProducts. -- This query also supports paging and sorting. WITH UmbracoOverview As ( SELECT ROW_NUMBER() OVER( ORDER BY CASE WHEN @sortExpression = 'productName' THEN umbracoProduct.productName WHEN @sortExpression = 'productCode' THEN umbracoProduct.productCode END ASC, CASE WHEN @sortExpression = 'productName DESC' THEN umbracoProduct.productName WHEN @sortExpression = 'productCode DESC' THEN umbracoProduct.productCode END DESC ) AS row_num, umbracoProduct.umbracoProductId, umbracoProduct.productName, umbracoProduct.productCode FROM umbracoProduct INNER JOIN product ON umbracoProduct.umbracoProductId = product.umbracoProductId WHERE (umbracoProduct.productName LIKE @searchText OR umbracoProduct.productCode LIKE @searchText OR product.code LIKE @searchText OR product.description LIKE @searchText OR product.descriptionLong LIKE @searchText OR product.unitCode LIKE @searchText) ) SELECT UmbracoOverview.UmbracoProductId, UmbracoOverview.productName, UmbracoOverview.productCode FROM UmbracoOverview WHERE (row_num >= @startRowIndex AND row_num < (@startRowIndex + @maximumRows)) -- This query will count all the UmbracoProducts. -- This query is used for paging inside ASP.NET. SELECT COUNT (umbracoProduct.umbracoProductId) AS CountNumber FROM umbracoProduct INNER JOIN product ON umbracoProduct.umbracoProductId = product.umbracoProductId WHERE (umbracoProduct.productName LIKE @searchText OR umbracoProduct.productCode LIKE @searchText OR product.code LIKE @searchText OR product.description LIKE @searchText OR product.descriptionLong LIKE @searchText OR product.unitCode LIKE @searchText) END This is my Linq to LLBLGen query: using System.Linq.Dynamic; var q = ( from up in MetaData.UmbracoProduct join p in MetaData.Product on up.UmbracoProductId equals p.UmbracoProductId where up.ProductCode.Contains(searchText) || up.ProductName.Contains(searchText) || p.Code.Contains(searchText) || p.Description.Contains(searchText) || p.DescriptionLong.Contains(searchText) || p.UnitCode.Contains(searchText) select new UmbracoProductOverview { UmbracoProductId = up.UmbracoProductId, ProductName = up.ProductName, ProductCode = up.ProductCode } ).OrderBy(sortExpression); //Save the count in HttpContext.Current.Items. This value will only be saved during 1 single HTTP request. HttpContext.Current.Items["AllProductsCount"] = q.Count(); //Returns the results paged. return q.Skip(startRowIndex).Take(maximumRows).ToList<UmbracoProductOverview>(); This is my Initial expression to process: value(SD.LLBLGen.Pro.LinqSupportClasses.DataSource`1[Eurofysica.DB.EntityClasses.UmbracoProductEntity]).Join(value(SD.LLBLGen.Pro.LinqSupportClasses.DataSource`1[Eurofysica.DB.EntityClasses.ProductEntity]), up => up.UmbracoProductId, p => p.UmbracoProductId, (up, p) => new <>f__AnonymousType0`2(up = up, p = p)).Where(<>h__TransparentIdentifier0 => (((((<>h__TransparentIdentifier0.up.ProductCode.Contains(value(Eurofysica.BusinessLogic.BLL.Controllers.UmbracoProductController+<>c__DisplayClass1).searchText) || <>h__TransparentIdentifier0.up.ProductName.Contains(value(Eurofysica.BusinessLogic.BLL.Controllers.UmbracoProductController+<>c__DisplayClass1).searchText)) || <>h__TransparentIdentifier0.p.Code.Contains(value(Eurofysica.BusinessLogic.BLL.Controllers.UmbracoProductController+<>c__DisplayClass1).searchText)) || <>h__TransparentIdentifier0.p.Description.Contains(value(Eurofysica.BusinessLogic.BLL.Controllers.UmbracoProductController+<>c__DisplayClass1).searchText)) || <>h__TransparentIdentifier0.p.DescriptionLong.Contains(value(Eurofysica.BusinessLogic.BLL.Controllers.UmbracoProductController+<>c__DisplayClass1).searchText)) || <>h__TransparentIdentifier0.p.UnitCode.Contains(value(Eurofysica.BusinessLogic.BLL.Controllers.UmbracoProductController+<>c__DisplayClass1).searchText))).Select(<>h__TransparentIdentifier0 => new UmbracoProductOverview() {UmbracoProductId = <>h__TransparentIdentifier0.up.UmbracoProductId, ProductName = <>h__TransparentIdentifier0.up.ProductName, ProductCode = <>h__TransparentIdentifier0.up.ProductCode}).OrderBy( => .ProductName).Count() Now this is how the queries look like that are send to sql server: Select query: Query: SELECT [LPA_L2].[umbracoProductId] AS [UmbracoProductId], [LPA_L2].[productName] AS [ProductName], [LPA_L2].[productCode] AS [ProductCode] FROM ( [eurofysica].[dbo].[umbracoProduct] [LPA_L2] INNER JOIN [eurofysica].[dbo].[product] [LPA_L3] ON [LPA_L2].[umbracoProductId] = [LPA_L3].[umbracoProductId]) WHERE ( ( ( ( ( ( ( ( [LPA_L2].[productCode] LIKE @ProductCode1) OR ( [LPA_L2].[productName] LIKE @ProductName2)) OR ( [LPA_L3].[code] LIKE @Code3)) OR ( [LPA_L3].[description] LIKE @Description4)) OR ( [LPA_L3].[descriptionLong] LIKE @DescriptionLong5)) OR ( [LPA_L3].[unitCode] LIKE @UnitCode6)))) Parameter: @ProductCode1 : String.

Value: "%%". As you can see no sorting or paging is done (like in my Stored Procedure). This is probably done inside the code after all the results are fetched. This costs a lot of performance! Does anybody know how I can convert my Stored Procedure to Linq to LLBLGen the proper way?

  • .NETCF Component that allows entering a signature

    - by Vaccano
    I need a component that will allow me to enter a signature on a Windows Mobile 5 device. I need to integrate it into my .NETCF program. I would prefer it be free (getting budget approval takes so long). (I have seen the "for pay" one by Resco.) I would need to end up storing the signature in a SQL Server database (it has to be able to serialize). If anyone has any suggestions I would love to hear them.
