  • Automatically add links to class source files under a specified directory of an another project in V

    - by Binary255
    I want to share some class source files between two projects in Visual Studio 2008. I can't create a project for the common parts and reference it (see my comment if you are curious to why). I've managed to share some source files, but it could be a lot more neat. I've created a test solution called Commonality. The Solution Explorer of the Commonality solution which contains project One and Two: What I like: All class files under the Common folder of project One are automatically added to project Two by linking. It's mostly the same as if I would have chosen Add / Existing Item... : Add As Link on each new class source file. It's clear that these files have been linked in. The shortcut arrow symbol is marking each file icon. What I do not like: The file and folder tree structure under Common of project One isn't included. It's all flat. The linked source files are shown under the project root of project Two. It would look much less cluttered if they were located under Common like in project One. The file tree structure of the Commonality solution which contains project One and Two: $ tree /F /A Folder PATH listing for volume Cystem Volume serial number is 0713370 1337:F6A4 C:. | Commonality.sln | +---One | | One.cs | | One.csproj | | | +---bin | | \---Debug | | One.vshost.exe | | One.vshost.exe.manifest | | | +---Common | | | Common.cs | | | CommonTwo.cs | | | | | \---SubCommon | | CommonThree.cs | | | +---obj | | \---Debug | | +---Refactor | | \---TempPE | \---Properties | AssemblyInfo.cs | \---Two | Two.cs | Two.csproj | Two.csproj.user | Two.csproj~ | +---bin | \---Debug +---obj | \---Debug | +---Refactor | \---TempPE \---Properties AssemblyInfo.cs And the relevant part of project Two's project file Two.csproj: <ItemGroup> <Compile Include="..\One\Common\**\*.cs"> </Compile> <Compile Include="Two.cs" /> <Compile Include="Properties\AssemblyInfo.cs" /> </ItemGroup> How do I address what I do not like, while keeping what I like?

  • Insert records using ExecuteNonQuery, showing exception that invalid column name

    - by tina
    Hi all, I am using SQL Server 2008. I want to insert records into a table using ExecuteNonQuery, for that I have written: customUtility.ExecuteNonQuery("insert into furniture_ProductAccessories(Product_id, Accessories_id, SkuNo, Description1, Price, Discount) values(" + prodid + "," + strAcc + "," + txtSKUNo.Text + "," + txtAccDesc.Text + "," + txtAccPrices.Text + "," + txtAccDiscount.Text + ")"); & following is ExecuteNonQuery function: public static bool ExecuteNonQuery(string SQL) { bool retVal = false; using (SqlConnection con = new SqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings["dbConnect"].ToString())) { con.Open(); SqlTransaction trans = con.BeginTransaction(); SqlCommand command = new SqlCommand(SQL, con, trans); try { command.ExecuteNonQuery(); trans.Commit(); retVal = true; } catch(Exception ex) { //HttpContext.Current.Response.Write(SQL + "<br>" + ex.Message); //HttpContext.Current.Response.End(); } finally { // Always call Close when done reading. con.Close(); } return retVal; } } but it showing exception that invalid column name to Description1 and even it's value which coming from txtAccDesc.Text. I have tried by removing Description1 column, other records are getting inserted successfully. Could you please help me? Thanks.

  • bad_alloc occuring when allocating small structs

    - by SalamiArmi
    A bad_alloc has started showing up in some code which looks perfectly valid to me and has worked very well in the past. The bad alloc only occurs once every 50-3000 iterations of the code, which is also confusing. The code itself is from a singly linked list, simply adding a new element to the queue: template<typename T> struct container { inline container() : next(0) {} container *next; T data; }; void push(const T &data) { container<T> *newQueueMember = new container<T>; //... unrelated to crash } Where T is: struct test { int m[256]; }; Changing the size of the array allocated array to anything but very small values (1-8 ints) still results in a bad_alloc occasionally. A few extra notes about my program: - I used Poco::ThreadPool to thread my program. I've only recently added this functionality, before I had it running with Win32 threads. However, only the main thread ever calls push(). - I am also occasionally getting other crashes which could be related. However, when I try to debug with visual studio 2008, I can't navigate back to the call stack, or the crash happens deep within new(). Thanks in advance.

  • Does SetFileBandwidthReservation affect memory-mapped file performance?

    - by Ghostrider
    Does this function affect Memory-mapped file performance? Here's the problem I need to solve: I have two applications competing for disk access: "reader" and "updater". Whole system runs on Windows Server 2008 R2 x64 "Updater" constantly accesses disk in a linear manner, updating data. They system is set up in such a way that updater always has infinite data to update. Consider that it is constantly approximating a solution of a huge set of equations that takes up entire 2TB disk drive. Updater uses ReadFile and WriteFile to process data in a linear fashion. "Reader" is occasionally invoked by user to get some pieces of data. Usually user would read several 4kb blocks from the drive and stop. Occasionally user needs to read up to 100mb sequentially. In exceptional cases up to several gigabytes. Reader maps files to memory to get data it needs. What I would like to achieve is for "reader" to have absolute priority so that "updater" would completely stop if needed so that "reader" could get the data user needs ASAP. Is this problem solvable by using SetPriorityClass and SetFileBandwidthReservation calls? I would really hate to put synchronization login in "reader" and "updater" and rather have the OS take care of priorities.

  • Global resources can't be resolved after publishing Website in VS2008

    - by Scoregraphic
    Hi there I have a web-project running in VS 2008. We have some global resource files (*.resx) in the App_GlobalResources folder for internationalisation. All this works like a charm on my local IIS installation out of VS. But when I publish my web-project to the local filesystem and/or another server, all the resources can no longer be found. So I guess the pre-compilation is somehow corrupting stuff. When I call the pre-compiled web, I get an error that the resource object with key xyz cannot be found, although it could be found before. I checked with .NET reflector if the resource stuff made it into the *.dlls. All those identifiers are there (bin/Web.dll, bin/<culture>/Web.resources.dll). The identifiers are loaded like this: <asp:MenuItem NavigateUrl="~/OrderNew.aspx" Text="<%$ Resources:MyProject, MenuNewOrder %>" Value="NewOrder"> The resource files are called MyProject.resx and MyProject.<culture>.resx where <culture> corresponds the the specific culture (i.e. MyProject.de-DE.resx). Any ideas how to solve this? I really appreciate any help. Thanks Edit: If I copy the App_GlobalResources folder manually to the output, the resources may be loaded normally. So I really really wonder what this pre-compilation is all about. I'm still interested in solving the issue "the right way".

  • TransactionScope question - how can I keep the DTC from getting involved in this?

    - by larryq
    (I know the circumstances surrounding the DTC and promoting a transaction can be a bit mysterious to those of us not in the know, but let me show you how my company is doing things, and if you can tell me why the DTC is getting involved, and if possible, what I can do to avoid it, I'd be grateful.) I have code running on an ASP.Net webserver. We have one database, SQL 2008. Our data access code looks something like this-- We have a data access layer that uses a wrapper object for SQLConnections and SQLCommands. Typical use looks like this: void method1() { objDataObject = new DataAccessLayer(); objDataObject.Connection = SomeConnectionMethod(); SqlCommand objCommand = DataAccessUtils.CreateCommand(SomeStoredProc); //create some SqlParameters, add them to the objCommand, etc.... objDataObject.BeginTransaction(IsolationLevel.ReadCommitted); objDataObject.ExecuteNonQuery(objCommand); objDataObject.CommitTransaction(); objDataObject.CloseConnection(); } So indeed, a very thin wrapper around SqlClient, SqlConnection etc. I want to run several stored procs in a transaction, and the wrapper class doesn't allow me access to the SqlTransaction so I can't pass it from one component to the next. This led me to use a TransactionScope: using (TransactionScope tx1 = new TransactionScope(TransactionScope.RequiresNew)) { method1(); method2(); method3(); tx1.Complete(); } When I do this, the DTC gets involved, and unfortunately our webservers don't have "allow remote clients" enabled in the MSDTC settings-- getting IT to allow that will be a fight. I'd love to avoid DTC becoming involved but can I do it? Can I leave out the transactional calls in methods1-3() and just let the TransactionScope figure it all out?

  • .NET - Is there a way to programmatically fill all tables in a strongly-typed dataset?

    - by Mike Loux
    Hello, all! I have a SQL Server database for which I have created a strongly-typed DataSet (using the DataSet Designer in Visual Studio 2008), so all the adapters and select commands and whatnot were created for me by the wizard. It's a small database with largely static data, so I would like to pull the contents of this DB in its entirety into my application at startup, and then grab individual pieces of data as needed using LINQ. Rather than hard-code each adapter Fill call, I would like to see if there is a way to automate this (possibly via Reflection). So, instead of: Dim _ds As New dsTest dsTestTableAdapters.Table1TableAdapter.Fill(_ds.Table1) dsTestTableAdapters.Table2TableAdapter.Fill(_ds.Table2) <etc etc etc> I would prefer to do something like: Dim _ds As New dsTest For Each tableName As String In _ds.Tables Dim adapter as Object = <routine to grab adapter associated with the table> adapter.Fill(tableName) Next Is that even remotely doable? I have done a fair amount of searching, and I wouldn't think this would be an uncommon request, but I must be either asking the wrong question, or I'm just weird to want to do this. I will admit that I usually prefer to use unbound controls and not go with strongly-typed datasets (I prefer to write SQL directly), but my company wants to go this route, so I'm researching it. I think the idea is that as tables are added, we can just refresh the DataSet using the Designer in Visual Studio and not have to make too many underlying DB code changes. Any help at all would be most appreciated. Thanks in advance!

  • How to make active services highly available?

    - by Jader Dias
    I know that with Network Load Balancing and Failover Clusteringwe can make passive services highly available. But what about active apps? Example: One of my apps retrieves some content from a external resource in a fixed interval. I have imagined the following scenarios: Run it in a single machine. Problem: if this instance falls, the content won't be retrieved Run it in each machine of the cluster. Problem: the content will be retrieved multiple times Have it in each machine of the cluster, but run it only in one of them. Each instance will have to check some sort of common resource to decide whether it its turn to do the task or not. When I was thinking about the solution #3 I have wondered what should be the common resource. I have thought of creating a table in the database, where we could use it to get a global lock. Is this the best solution? How does people usually do this? By the way it's a C# .NET WCF app running on Windows Server 2008

  • Subscribe through API .net C#

    I have to submit subscription data to another website. I have got documentation on how to use this API however i'm not 100% sure of how to set this up. I do have all the information needed, like username / passwords etc. This is the API documentation: https://www.apiemail.net/api/documentation/?SID=4 How would my request / post / whatever look like in C# .net (vs 2008) when i'm trying to acces this API? This is what i have now, I think i'm not on the right track: public static string GArequestResponseHelper(string url, string token, string username, string password) { HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url); myRequest.Headers.Add("Username: " + username); myRequest.Headers.Add("Password: " + password); HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse(); Stream responseBody = myResponse.GetResponseStream(); Encoding encode = System.Text.Encoding.GetEncoding("utf-8"); StreamReader readStream = new StreamReader(responseBody, encode); //return string itself (easier to work with) return readStream.ReadToEnd(); Hope someone knows how to set this up properly.

  • IIS site always returns 404 to WinMo emulator

    - by Derick Bailey
    I'm running Win7x64 Ultimate with Visual Studio 2008. I have a website built in ASP.NET 3.5 and hosted via IIS on my box. I can run the website perfectly fine and I can hit all of the web services that I have built in the website, using a web browser. When I pull up my Windows Mobile 6 emulator and hit the site (using my IP address) it always returns a 404 error. I have the emulator cradled w/ Device Emulator Manager and I can interact with the emulated device normally. I am also able to get out to google.com and other websites w/ the emulated device. I have also verified that the emulator is hitting my box by stopping the IIS website and seeing that the WinMo emulator cannot get any response. Then when I start the site again, I get a 404 error. When I pull up my site on my local dev box via FireFox or IE using the IP address it works perfectly fine. The worst part is this worked perfectly fine a few weeks ago, when I used it last. I don't know that I've changed anything since then - I'm just trying to use the emulator to hit my site again. Help?! Update: my http requests comign from the WinMo emulator are not getting logged in the IIS log files, while my requests from FireFox on my local box are getting logged. Not sure if that helps in figuring out the problem... Update 2: I can use the ruby Webbrick server on my local box and hit that server from my emulator just fine. is in IIS not allowing me to hit the IIS site from the emu? UPdate 3: I cradled an actual WinMo device to my box with it's networking turned off and was able to hit the IIS site just fine. that makes me think it's something set up wrong in the emulator.

  • Working with Decimal fields in SSIS

    - by CoffeeAddict
    I'm using SQL Server 2008 w/SP2. I've got an incoming decimal(9,2) field incoming through my OLE DB transformation to my recordset destination transformation. It's like it's reading it as something other than a decimal? I don't know..I'm not an SSIS guru. So continuing on...the problem I have starts here with me trying to stuff the value into a variable for this decimal field. In a foreach loop, I have a variable to represent this decimal field so I can work with it. The first problem that I believe is pretty well known is SSIS variables do not have a decimal type. And from my own testing and what I've read out there, people are using type object for the variable to make SSIS "happy" with decimal values? It makes mine happy. But, then in my foreach loop, I have a for loop. And inside that I'm using an E*xecute SQL Task transformation*. In it, I need to create a parameter mapping to my variable so I can work with that decimal field in my T-SQL call in here. So now I see a type decimal for the parameter and use it and set that to point to my variable. When I run SSIS and it hits my SQL call, I get this in my output window.: The type is not supported.DBTYPE_DECIMAL So I am hitting a wall here. All I wanna do is work with a decimal!!!

  • Selecting data in clustered index order without ORDER BY

    - by kcrumley
    I know there is no guarantee without an ORDER BY clause, but are there any techniques to tune SQL Server tables so they're more likely to return rows in clustered index order, without having to specify ORDER BY every single time I want to run a super-quick ad hoc query? For example, would rebuilding my clustered index or updating statistics help? I'm aware that I can't count on a query like: select * from AuditLog where UserId = 992 to return records in the order of the clustered index, so I would never build code into an application based on this assumption. But for simple ad hoc queries, on almost all of my tables, the data consistently comes out in clustered index order, and I've gotten used to being able to expect the most recent results to be at the bottom. Out of all the many tables we use, I've only noticed two ever giving me results in an unpredicted order. This is really just an annoyance, but it would be nice to be able to minimize it. In case this is relevant because of page boundary issues or something like that, I should mention that one of the tables that has inconsistent ordering, the AuditLog table, is the longest table we have that has a clustered index on an identity column. Also, this database has recently been moved from SQL 2005 to SQL 2008, and we've seen no noticeable change in this behavior.

  • Is this a bug or something I am doing wrong?

    - by Brian Gideon
    I cannot imagine how this is anything other than a bug, but since I do not currently have a login for the MS Connect website I will ask here first. I have Visual Studio 2008 SP 1 with all post SP1 hotfixes I could find relating to the crash installed. Can you reproduce the following crash? 1) Create a new "WPF Application" project using VB as the language (though I suspect it will happen in C# as well). 2) Enter the following code in the Window1.xaml.vb file. Friend MustInherit Class A End Class Friend MustInherit Class A(Of T) Inherits A End Class 3) Add a namespace declaration the Window1.xaml file so that it looks like the following. <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300"> <Grid> </Grid> </Window> 4) Now attempt to edit the xaml file by opening a new xml tag via the < character. 5) CRASH! Edit: Microsoft has confirmed this bug. The issue still exists in VS2010 beta 2, but will be fixed in the next release.

  • copy entire row (without knowing field names)

    - by Todd Webb
    Using SQL Server 2008, I would like to duplicate one row of a table, without knowing the field names. My key issue: as the table grows and mutates over time, I would like this copy-script to keep working, without me having to write out 30+ ever-changing fields, ugh. Also at issue, of course, is IDENTITY fields cannot be copied. My code below does work, but I wonder if there's a more appropriate method than my thrown-together text string SQL statement? So thank you in advance. Here's my (yes, working) code - I welcome suggestions on improving it. Todd alter procedure spEventCopy @EventID int as begin -- VARS... declare @SQL varchar(8000) -- LIST ALL FIELDS (*EXCLUDE* IDENTITY FIELDS). -- USE [BRACKETS] FOR ANY SILLY FIELD-NAMES WITH SPACES, OR RESERVED WORDS... select @SQL = coalesce(@SQL + ', ', '') + '[' + column_name + ']' from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'EventsTable' and COLUMNPROPERTY(OBJECT_ID('EventsTable'), COLUMN_NAME, 'IsIdentity') = 0 -- FINISH SQL COPY STATEMENT... set @SQL = 'insert into EventsTable ' + ' select ' + @SQL + ' from EventsTable ' + ' where EventID = ' + ltrim(str(@EventID)) -- COPY ROW... exec(@SQL) -- REMEMBER NEW ID... set @EventID = @@IDENTITY -- (do other stuff here) -- DONE... -- JUST FOR KICKS, RETURN THE SQL STATEMENT SO I CAN REVIEW IT IF I WISH... select EventID = @EventID, SQL = @SQL end

  • Something confusing about FormsOf (Sql server Full-Text searching)

    - by AspOnMyNet
    hi I'm using Sql Server 2008 1) A given <simple_term> within a <generation_term> will not match both nouns and verbs. If I understand the above text correctly, then query SELECT * FROM someTable WHERE CONTAINS ( *, ' FORMSOF ( INFLECTIONAL, park ) ' ) should search for either nouns or verbs derived from the root word “park”, but not for both? Thus out of the two rows, one containing noun parks and other verb parking, the above query should return just one of the two rows? But as it turns out, query returns both rows, so are perhaps my assumptions a bit off or is the above quote wrong?! 2) From Msdn: If freetext_string is enclosed in double quotation marks, a phrase match is instead performed; stemming and thesaurus are not performed. According to the above quote the following query shouldn’t return rows containing strings surfing ( due to query not performing stemming ), surf ( due to query performing phrase matching and not individual word matching ) and surfing with suzy’s sister ( due to query not performing stemming and due to query performing phrase matching and not word matching ), but it does. Thus, it appears that even when *freetext_string* is enclosed in double quotation marks, stemming is still preformed, while phrase matching is not: SELECT * FROM someTable WHERE FREETEXT( *, ' "surf sister" ' ) So is the above quote wrong or...? thanx

  • Conversion failed when converting the varchar value to int

    - by onedaywhen
    Microsoft SQL Server 2008 (SP1), getting an unexpected 'Conversion failed' error. Not quite sure how to describe this problem, so below is a simple example. The CTE extracts the numeric portion of certain IDs using a search condition to ensure a numeric portion actually exists. The CTE is then used to find the lowest unused sequence number (kind of): CREATE TABLE IDs (ID CHAR(3) NOT NULL UNIQUE); INSERT INTO IDs (ID) VALUES ('A01'), ('A02'), ('A04'), ('ERR'); WITH ValidIDs (ID, seq) AS ( SELECT ID, CAST(RIGHT(ID, 2) AS INTEGER) FROM IDs WHERE ID LIKE 'A[0-9][0-9]' ) SELECT MIN(V1.seq) + 1 AS next_seq FROM ValidIDs AS V1 WHERE NOT EXISTS ( SELECT * FROM ValidIDs AS V2 WHERE V2.seq = V1.seq + 1 ); The error is, 'Conversion failed when converting the varchar value 'RR' to data type int.' I can't understand why the value ID = 'ERR' should be being considered for conversion because the predicate ID LIKE 'A[0-9][0-9]' should have removed the invalid row from the resultset. When the base table is substituted with an equivalent CTE the problem goes away i.e. WITH IDs (ID) AS ( SELECT 'A01' UNION ALL SELECT 'A02' UNION ALL SELECT 'A04' UNION ALL SELECT 'ERR' ), ValidIDs (ID, seq) AS ( SELECT ID, CAST(RIGHT(ID, 2) AS INTEGER) FROM IDs WHERE ID LIKE 'A[0-9][0-9]' ) SELECT MIN(V1.seq) + 1 AS next_seq FROM ValidIDs AS V1 WHERE NOT EXISTS ( SELECT * FROM ValidIDs AS V2 WHERE V2.seq = V1.seq + 1 ); Why would a base table cause this error? Is this a known issue? UPDATE @sgmoore: no, doing the filtering in one CTE and the casting in another CTE still results in the same error e.g. WITH FilteredIDs (ID) AS ( SELECT ID FROM IDs WHERE ID LIKE 'A[0-9][0-9]' ), ValidIDs (ID, seq) AS ( SELECT ID, CAST(RIGHT(ID, 2) AS INTEGER) FROM FilteredIDs ) SELECT MIN(V1.seq) + 1 AS next_seq FROM ValidIDs AS V1 WHERE NOT EXISTS ( SELECT * FROM ValidIDs AS V2 WHERE V2.seq = V1.seq + 1 );

  • How to make std::vector's operator[] compile doing bounds checking in DEBUG but not in RELEASE

    - by Edison Gustavo Muenz
    I'm using Visual Studio 2008. I'm aware that std::vector has bounds checking with the at() function and has undefined behaviour if you try to access something using the operator [] incorrectly (out of range). I'm curious if it's possible to compile my program with the bounds checking. This way the operator[] would use the at() function and throw a std::out_of_range whenever something is out of bounds. The release mode would be compiled without bounds checking for operator[], so the performance doesn't degrade. I came into thinking about this because I'm migrating an app that was written using Borland C++ to Visual Studio and in a small part of the code I have this (with i=0, j=1): v[i][j]; //v is a std::vector<std::vector<int> > The size of the vector 'v' is [0][1] (so element 0 of the vector has only one element). This is undefined behaviour, I know, but Borland is returning 0 here, VS is crashing. I like the crash better than returning 0, so if I can get more 'crashes' by the std::out_of_range exception being thrown, the migration would be completed faster (so it would expose more bugs that Borland was hiding).

  • SSIS - Skip Missing Files

    - by Greg
    I have a SSIS 2008 package that calls about 10 other SSIS packages (legacy issues, don't ask). Each of those child packages loads a specific file into a table. But sometimes one or more of these input files will be missing. How can I let a child package fail (because a file is missing) but let the rest of the parent package keep on running? I've tried increasing the maximum error count on the parent package, the tasks in the parent package that call each child, and in the child package itself. None of that seemed to make any difference. I still get this error when I run it with a file missing: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors. Edit: failpackageonfailure and faulparentonfailure are already all set to false everywhere.

  • (nested) user controls within a mvp pattern causing sporadic problems

    - by LLEA
    hi everyone, I have a serious problem with nested user controls (UCs) in WinForms while trying to implement the mvp pattern (passive view). The project consists of one model (designed as a singleton) and a set of different presenters with corresponding view interfaces. To avoid one huge view interface and therefore an overloaded main UI, I decided to make use of a set of different UCs. Each UC has one view interface and one presenter that can access the model. But there are nested UCs: meaning that one specialised UC implements sort of a basic UC. The main UI just represents a container for all those UCs. So far, so good (if not, please ask)?! There are two problems that I am facing now (but I guess both are of the same origin): From time to time it is not possible anymore to load the UCs and test them within the Visual Studio 2008 User Control Test Container. The error message just says that a project with an output type of class library cannot be started directly etc. I can "handle" that by unloading all UC projects and reloading them afterwards. (I guess the references to all mvp components and other UCs are then updated). Assuming that the implementation of my mvp pattern is okay and all those UCs are testable within the VS Test Container at a certain time - there is the biggest problem still left: I am not able to add any UC (even the basic and unnested ones) to a simple Form (UI). The error message: error message.jpg Could it be that my basic UC causes all these Problems?! It consists of two simple ComboBoxes and implements a basic presenter and basic view interface. Whenever I add this UC to a different UC the VS designer adds two references to the public getter methods of the UC as resources. I then manually remove those resources from the resx-file and commend the corresponding lines in the designer file. thx in advance

  • Is it possible to definitively identify whether a DML command was issued from a stored procedure?

    - by Ed Harper
    I have inherited a SQL Server 2008 database to which calling applications have access through stored procedures. Each table in the database has a shadow audit table into which Insert/Update/Delete operations for are logged. Performance testing on populating the audit tables showed that inserting the audit records using OUTPUT clauses was 20% or so faster than using triggers, so this has been implemented in the stored procedures. However, because this design cannot track changes made directly to the tables through DML statements issued directly against the tables, triggers have also been implemented which use the value of @@NESTLEVEL to determine whether or not to run the trigger (the assumption being that all DML run through stored procedures will have @@NESTLEVEL 1). i.e. the body of the trigger code looks something like: IF @@NESTLEVEL = 1 -- implies call is direct sql so generate history from here BEGIN ... insert into audit table This design is flawed because it won't track updates where DML statements are executed in dynamic SQL, or any other context where @@NESTLEVEL is raised above 1. Can anyone suggest a completely reliable method we can use in the triggers to execute them only if not triggered by a stored procedure? Or is this (as I suspect) not possible?

  • Debugged Program Window Won't Close

    - by Marc Bernier
    Hi, I'm using VS 2008 on a 64-bit XP machine. I'm debugging a 32-bit C++ DLL via a console program. The DLL and EXE projects are contained in the same SLN so that I can modify the DLL as I test. What happens is that every once in a while I kill the program with Debug | Stop Debugging (Shift-F5). VS stops the program, but the console window stays open! If I'm sitting at a breakpoint and hit Shift-F5, it will terminate properly, but if the program is running full-tilt when I stop it, I often see this instead. The big problem is that I can't close these zombie windows. Using End Task in Task Manager does nothing (no message, no nothing). When I shut down the machine, it is unable to due to the orphans and I have to resort to actually turning off the power. I think this is connected to having the DLL and EXE project in the same SLN, as for months I worked on this project in 2 VS instances, one for the DLL and the other for the EXE. I would continually jump back and forth between the windows as I worked. This problem never happened until I put the two projects into a single SLN. The single SLN works a lot better, but this anomaly is very irritating. Any ideas anyone? UPDATE After a bit of searching (here), I found that it appears to have to do with one of the updates from last Tuesday (KB977165 or KB978037). Thank you Microsoft for your excellent pre-release testing.

  • error invoking store procedure with input parameter from ADO.Net

    - by George2
    Hello everyone, I am using VSTS 2008 + C# + .Net 3.5 + ADO.Net. Here is my code and related error message. The error message says, @Param1 is not supplied, but actually it is supplied in my code. Any ideas what is wrong? System.Data.SqlClient.SqlException: Procedure or function 'Pr_Foo' expects parameter '@Param1', which was not supplied. class Program { private static SqlCommand _command; private static SqlConnection connection; private static readonly string _storedProcedureName = "Pr_Foo"; private static readonly string connectionString = "server=.;integrated Security=sspi;initial catalog=FooDB"; public static void Prepare() { connection = new SqlConnection(connectionString); connection.Open(); _command = connection.CreateCommand(); _command.CommandText = _storedProcedureName; _command.CommandType = CommandType.StoredProcedure; } public static void Dispose() { connection.Close(); } public static void Run() { try { SqlParameter Param1 = _command.Parameters.Add("@Param1", SqlDbType.Int, 300101); Param1.Direction = ParameterDirection.Input; SqlParameter Param2 = _command.Parameters.Add("@Param2", SqlDbType.Int, 100); portal_SiteInfoID.Direction = ParameterDirection.Input; SqlParameter Param3 = _command.Parameters.Add("@Param3", SqlDbType.Int, 200); portal_RoleInfoID.Direction = ParameterDirection.Input; _command.ExecuteScalar(); } catch (Exception e) { Console.WriteLine(e); } } static void Main(string[] args) { try { Prepare(); Thread t1 = new Thread(Program.Run); t1.Start(); t1.Join(); Dispose(); } catch (Exception ex) { Console.WriteLine(ex.Message + "\t" + ex.StackTrace); } } } thanks in avdance, George

  • Two radically different queries against 4 mil records execute in the same time - one uses brute force.

    - by IanC
    I'm using SQL Server 2008. I have a table with over 3 million records, which is related to another table with a million records. I have spent a few days experimenting with different ways of querying these tables. I have it down to two radically different queries, both of which take 6s to execute on my laptop. The first query uses a brute force method of evaluating possibly likely matches, and removes incorrect matches via aggregate summation calculations. The second gets all possibly likely matches, then removes incorrect matches via an EXCEPT query that uses two dedicated indexes to find the low and high mismatches. Logically, one would expect the brute force to be slow and the indexes one to be fast. Not so. And I have experimented heavily with indexes until I got the best speed. Further, the brute force query doesn't require as many indexes, which means that technically it would yield better overall system performance. Below are the two execution plans. If you can't see them, please let me know and I'll re-post then in landscape orientation / mail them to you. Brute-force query: Index-based exception query: My question is, based on the execution plans, which one look more efficient? I realize that thing may change as my data grows.

  • Modify SQL result set before returning from stored procedure

    - by m0sa
    I have a simple table in my SQL Server 2008 DB: Tasks_Table -id -task_complete -task_active -column_1 -.. -column_N The table stores instructions for uncompleted tasks that have to be executed by a service. I want to be able to scale my system in future. Until now only 1 service on 1 computer read from the table. I have a stored procedure, that selects all uncompleted and inactive tasks. As the service begins to process tasks it updates the task_active flag in all the returned rows. To enable scaleing of the system I want to enable deployment of the service on more machines. Because I want to prevent a task being returned to more than 1 service I have to update the stored procedure that returns uncompleted and inactive tasks. I figured that i have to lock the table (only 1 reader at a time - I know I have to use an apropriate ISOLATION LEVEL), and updates the task_active flag in each row of the result set before returning the result set. So my question is how to modify the SELECT result set iin the stored procedure before returning it?
