  • add assembly reference dialog

    - by codymanix
    Is there a way to use visual studio's "add assembly reference dialog" (or something similar) in my own application? I need it for dynamic code generation and compilation. This is not simply an OpenFileDialog, since it additionally looks into the GAC and so on, so it will be very complicated to do it on my own, I think. If this is not possible, how can I get a list of all assemblies from the GAC?

  • Regular expression not working after debugging

    - by Jaison
    I have an ASP.NET website with a regular expression validator text box. I have changed the expression in the regular expression validation property "validator expression" and after compiling (rebuild) and running, the validation CHANGEs are not reflecting. The previous validation is working fine but the changed validation is not working. Please help me! edit: First code: ([a-zA-Z0-9_-.]+)\@((base.co.uk)|(base.com)|(group.com)) Second code: @"([a-zA-Z0-9_\-.]+)@((base\.co\.uk)|(base\.com)|(group\.com)|(arg\.co\.uk)|(arggroup\.com))"

  • Return if remote stored procedure fails

    - by njk
    I am in the process of creating a stored procedure. This stored procedure runs local as well as external stored procedures. For simplicity, I'll call the local server [LOCAL] and the remote server [REMOTE]. USE [LOCAL] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[monthlyRollUp] AS SET NOCOUNT, XACT_ABORT ON BEGIN TRY EXEC [REOMTE].[DB].[table].[sp] --This transaction should only begin if the remote procedure does not fail BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp1] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp2] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp3] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp4] COMMIT END TRY BEGIN CATCH -- Insert error into log table INSERT INTO [dbo].[log_table] (stamp, errorNumber, errorSeverity, errorState, errorProcedure, errorLine, errorMessage) SELECT GETDATE(), ERROR_NUMBER(), ERROR_SEVERITY(), ERROR_STATE(), ERROR_PROCEDURE(), ERROR_LINE(), ERROR_MESSAGE() END CATCH GO When using a transaction on the remote procedure, it throws this error: OLE DB provider ... returned message "The partner transaction manager has disabled its support for remote/network transactions.". I get that I'm unable to run a transaction locally for a remote procedure. How can I ensure that the this procedure will exit and rollback if any part of the procedure fails?

  • Replication - User defined table type not propogating to subscriber

    - by Aamod Thakur
    I created a User defined table type named tvp_Shipment with two columns (id and name) . generated a snapshot and the User defined table type was properly propogated to all the subscribers. I was using this tvp in a stored procedure and everything worked fine. Then I wanted to add one more column created_date to this table valued parameter.I dropped the stored procedure (from replication too) and also i dropped and recreated the User defined table type with 3 columns and then recreated the stored procedure and enabled it for publication When i generate a new snapshot, the changes in user defined table type are not propogated to the subscriber. The newly added column was not added to the subscription. the Error messages: The schema script 'usp_InsertAirSa95c0e23_218.sch' could not be propagated to the subscriber. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147201001) Get help: http://help/MSSQL_REPL-2147201001 Invalid column name 'created_date'. (Source: MSSQLServer, Error number: 207) Get help: http://help/207

  • CTE and last known date processing

    - by stackoverflowuser
    Input @StartDate = '01/25/2010' @EndDate = '02/06/2010' I have 2 CTEs in a stored procedure as follows: with CTE_A as ( [gives output A..Shown below] ), with CTE_B as ( Here, I want to check if @StartDate is NOT in output A then replace it with the last known date. In this case, since @startdate is less than any date in output A hence @StartDate will become 02/01/2010. Also to check if @EndDate is NOT in output A then replace it with the last known date. In this case, since @enddate is 02/06/2010 hence it will be replace with 02/05/2010. // Here there is a query using @startDate and @EndDate. ) output A Name Date A 02/01/2010 B 02/01/2010 C 02/05/2010 D 02/10/2010

  • Weird "Designer1.cs" files created

    - by Neil Barnwell
    How does visual studio link files to their corresponding designer.cs files? I have a strange situation that's occurred with both the DataSet designer and also the L2S DBML designer where it's ignoring the DataSet.Designer.cs and has created and used a DataSet.Designer1.cs instead. How can I switch it back?

  • UrlRewriter.Net with URL with final dot

    - by devio
    I want to use UrlRewriter.Net as described in this blog by ScottGu. In the example below, page.aspx should display a page text stored in the database based on the title= URL parameter. After a couple of tweaks the only remaining issue seems to be that a final dot in the URL causes a 404 a sequence of two dots in the URL causes a 400 Windows 7, IIS 7 with Integrated AppPool, VS2008. Looking at the Failed Request Log, it seems that the UrlRewriter module is called after retrieving the request handler. Can these two issues be fixed, or is there a better replacement for UrlRewriter? (A related question only asks about the 404) Edit: This behavior can even be reproduced on SO, so maybe there is no work-around?

  • Ramifications of CheckForIllegalCrossThreadCalls=false

    - by Ron Skufca
    I recently updated an application from VS2003 to VS2008 and I knew I would be dealing with a host of "Cross-thread operation not valid: Control 'myControl' accessed from a thread other than the thread it was created on" I am handling this in what I beleive is the correct way (see code sample below). I am running into numerous controls that are going to need a similar fix. Not wanting to have similar code for every label, textbox etc.. that are being accessed by a non UI thread. What are the ramifications of just setting the CheckForIllegalCrossThreadCalls = false for the entire app? I found a CodeProject article with various workarounds and a warning at the bottom to NOT set the property. I am looking for other opinions/experiences on this issue. private void ShowStatus(string szStatus) { try { if (this.statusBar1.InvokeRequired) { BeginInvoke(new MethodInvoker(delegate() { ShowStatus(szStatus); })); } else { statusBar1.Panels[0].Text = szStatus; } } catch (Exception ex) { LogStatus.WriteErrorLog(ex, "Error", "frmMNI.ShowStatus()"); } }

  • Set HttpContext.Current.User from Thread.CurrentPrincipal

    - by Argons
    I have a security manager in my application that works for both windows and web, the process is simple, just takes the user and pwd and authenticates them against a database then sets the Thread.CurrentPrincipal with a custom principal. For windows applications this works fine, but I have problems with web applications. After the process of authentication, when I'm trying to set the Current.User to the custom principal from Thread.CurrentPrincipal this last one contains a GenericPrincipal. Am I doing something wrong? This is my code: Login.aspx protected void btnAuthenticate_Click(object sender, EventArgs e) { Authenticate("user","pwd"); FormsAuthenticationTicket authenticationTicket = new FormsAuthenticationTicket(1, "user", DateTime.Now, DateTime.Now.AddMinutes(30), false, ""); string ticket = FormsAuthentication.Encrypt(authenticationTicket); HttpCookie authenticationCookie = new HttpCookie(FormsAuthentication.FormsCookieName, ticket); Response.Cookies.Add(authenticationCookie); Response.Redirect(FormsAuthentication.GetRedirectUrl("user", false)); } Global.asax (This is where the problem appears) protected void Application_AuthenticateRequest(object sender, EventArgs e) { HttpCookie authCookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie == null) return; if (HttpContext.Current.User != null && HttpContext.Current.User.Identity.IsAuthenticated && HttpContext.Current.User.Identity is FormsIdentity) { HttpContext.Current.User = System.Threading.Thread.CurrentPrincipal; //Here the value is GenericPrincipal } Thanks in advance for any help. }

  • DebuggerDisplay attribute does not work as expected!

    - by mark
    Dear ladies and sirs. I know that this attribute should work in C# and yet, in my case it does not. I have a class with a lazy property Children. Accessing this property may have a side effect of roundtripping to the server. So, naturally, I do not want this to happen when I just watch it in the debugger watch window. Omitting all the irrelevant details the source looks pretty ordinary: [DebuggerDisplay("(Frozen) {m_children}")] public IList<IEntityBase> Children { get { if (m_children == null) { m_children = FetchChildrenFromDB(this); } return m_children; } } And yet, when I watch the object and expand this in the watch window I do not see (Frozen) in the display, meaning the debugger simply ignores the attribute. Provided the image link is still valid it should be visible below: http://i28.tinypic.com/2zxo9s5.jpg The attribute is really there, according to Reflector. I use VS2008. Any ideas?

  • Can SQL Server Compact be used as both a Source and Destination in SSIS?

    - by Rich
    I'm wondering if SQL Server Compact Edition can be used as both a Source and Destination in an SSIS dataflow. I know I can setup a SQLMOBILE connection manager, and I've found some information that mentions using it as a Destination, but nothing on using it as a Source. What I'm looking to do is to transfer data from one SQL Server Compact file to another.

  • New projects not built when target platform is set explicitly

    - by stiank81
    I create a new solution with one project, and then change the target platform from "Any CPU" to "x86". After this new projects added doesn't get built by default, and their target platform doesn't follow the global settings. Why?! Looking at the configuration manager new projects added are not checked to "Build", and they get target platform "Any CPU" instead of the globally set x86. Why is this happening? I expect new projects too to get the globally set and defined x86 target platform.. Some things I've tried: Toggle global platform back to Any CPU, and then to x86 again. No change.. Choosing platform explicitly for the new project. x86 is not available in the list, and when I say <New..> and try adding it I'm not allowed as ".. a solution platform with the same name already exists.". On the build properties for the new project I can't change the platform in the Configuration section, but I can set "Platform target" to x86 in the General section. It is however not clear whether this actually makes a difference, and it wouldn't respond if I change the target platform globally later. Initially I thought this was a problem from converting my solution from VS2008 to VS2010, but the problem applies both places. I.e. when I create a solution in VS2008 and just stay in VS2008 I still get the problem.

  • VSC++, virtual method at bad adress, curious bug

    - by antoon.groenewoud
    Hello, This guy: virtual phTreeClass* GetTreeClass() const { return (phTreeClass*)m_entity_class; } When called, crashed the program with an access violation, even after a full recompile. All member functions and virtual member functions had correct memory adresses (I hovered mouse over the methods in debug mode), but this function had a bad memory adress: 0xfffffffc. Everything looked okay: the 'this' pointer, and everything works fine up until this function call. This function is also pretty old and I didn't change it for a long time. The problem just suddenly popped up after some work, which I commented all out to see what was doing it, without any success. So I removed the virtual, compiled, and it works fine. I add virtual, compiled, and it still works fine! I basically changed nothing, and remember that I did do a full recompile earlier, and still had the error back then. I wasn't able to reproduce the problem. But now it is back. I didn't change anything. Removing virtual fixes the problem. Sincerely, Antoon
