Привет!
Работал ли кто-нибудь с GridControl.AdvBandedGridView? Мне нужно, чтобы в band я мог поместить другой band на один уровень с column. А компонент позволяет в band'е держать или другие band'ы или column'ы, но не то и другое одновременно. Подскажите, как можно обойти это или же сделать визуальную симуляцию такого размещения band и column?

Why does my c# application stop after receiving a callback from unmanaged DLL?

I've just encountered this very strange problem. And wonder why it could happen.

The similar situation is described by someone on MSDN-site.
http://social.msdn.microsoft.com/Forums/en-US/clr/thread/25bd7c1d-373f-4ef7-a64b-a101897b6b9a/

But nobody there brought a clear explanation of that yet.

This little article described how to deal with callbacks from unmanaged code.
http://www.codeproject.com/KB/cs/win32_to_net.aspx
I think I did everything properly so that the program works well. But it doesn't.
If necessary, I could share snippets of my code.

Thank you.

There are several ways to listen to an event with "+=". As a primarily-Java programmer I'm particulally drawn to the anonymous delegate. But if you want to subsequently remove the listener with -=, how can you identify the object? I guess it is not possible with the anonymous case, but even when you specify

MyEvent += MyInstanceMethod

a delegate for the MyInstanceMethod is being created... so will -= MyInstanceMethod remove the same object from the event's colection of listeners? Or do I have to create an explicit "new" instance of a delegate type, keep it on a field and "-=" the field?

I have the following:
                if (userDlg.ShowDialog(this) == DialogResult.Cancel)
                {
                    Application.Exit();
                }
But when I run the code, the application is not exiting when I click the cancel button on the userDlg dialog. Stepping through in the debugger it's hitting the Application.Exit(); line ok, but just carrying on!

So how can I get the program to terminate (neatly!) at this point?

Thanks in advance,

Tim

Is there a way to change what a mock returns from its faked methods or properies after it has been initialised?

For instance if I am testing myContainer to see if it supports repeated attempts to Add the same Foo instance regardless of the value of the Foo's boolean Bar property I want to do something like

myMockery = new Mockery();
myFoo = myMockery.NewMock();
Stub.On(myFoo).GetProperty("Bar").Will(Return.Value(false));
myCollection.Add( myFoo );
Stub.On(myFoo).GetProperty("Bar").Will(Return.Value(true));
myCollection.Add( myFoo );
Assert something about myCollection


But it seems that once you use "Stub.On" any subsequent Stub.On the same object has no effect?

I have an application in IIS where I set up a wildcard so that all file extensions are processed via the .net dll. I did this so that I can process some URL rewriting. I see at the top of the configuration screen where I can specify which extensions should be processed by what processors. What I am wondering is if there is a way to specify an extension that should not be processed by the wildcard. Specifically I know that .jpg, .gif, .css, .png and .js extensions should not go through it. Is there a way to tell IIS to just serve them normally?

Is there a .net photo album component similar to facebook's photo album? Its a cheap gimmick to be sure but I do like the way the next set of photos preloads and scrolls left. I imagine similar functionality could be used to display any grid data. Any suggestions?

I’m having some “fun” with client-side validation on a roll-my-own BaseValidator subclass.

My validator is to validate email format and includes the following code (with XMLdoc removed for brevity):

using System;
using System.Text.RegularExpressions;

namespace IrisDigital.WebControls.Validation
{
   [System.Web.UI.ToolboxData("<{0}:EmailValidator runat='server'/>")]
   public class EmailValidator : BaseValidator
   {
      protected override void AddAttributesToRender(System.Web.UI.HtmlTextWriter writer)
      {
         base.AddAttributesToRender(writer);

         if (base.RenderUplevel)
         {
            writer.AddAttribute("evaluationfunction", "CheckEmailFormat");
            writer.AddAttribute("controltovalidate", this.GetControlRenderID(this.ControlToValidate));
         }
      }

      protected override bool EvaluateIsValid()
      {
         // ...
      }

      protected override void OnPreRender(EventArgs e)
      {
         base.OnPreRender(e);

         if (base.RenderUplevel)
         {
            if (!Page.ClientScript.IsClientScriptBlockRegistered("IrisDigital.WebControls.Validation.EmailValidator"))
            {
               Page.ClientScript.RegisterClientScriptInclude("IrisDigital.WebControls.Validation.EmailValidator",
                  Page.ClientScript.GetWebResourceUrl(this.GetType(), "IrisDigital.WebControls.Validation.EmailValidator.js"));
            }
            this.ClientValidationFunction = "CheckEmailFormat";
         }
      }

Most of the rationale for doing things this way is from an article on CodeProject: RequiredIfValidator — Extending from the BaseValidator class, which does it precisely this way.

The validator works wonderfully. But the client-side validation never fires.

The WebResource correctly gets added to the page as a script include (for which I need to have the following line in my AssemblyInfo.cs, in case you were wondering):

[assembly: System.Web.UI.WebResource("IrisDigital.WebControls.Validation.EmailValidator.js", "text/javascript")]

, but it just never gets called.

Anyone got any ideas why?

First off, I'll state that I'm working with C# 2008 express edition, SQL Server 2008 Professional edition, and .NET 3.5.

Second, I'll state that one of the ideas behind this project is to do it without .Net's auto-binding. If it can't be done without auto-binding, it's not going to get done at all, for reasons having to do with extreme customization of the data access code that will be happening way, way down the line. So I need an answer in code, not in designer. Thanks.

Okay, what I'm doing seems to me to be simple and obvious, but either .Net doesn't agree with me or I'm looking in the wrong place. I have a simple form. It contains a datagridview and three buttons. One button works perfectly--it's the one that closes the form, and we don't need to discuss it here. The other two buttons, however, are giving me fits. They are labelled "save changes" and "cancel".

The datagridview is bound to a DataTable. This is pretty standard code, I think:

SqlConnection cnErasmus = new SqlConnection();
            //populate the datatable with the data already in the table.
            tblAuthorType = PopulateDataSet(cnErasmus);
            //Attach DataTable to datagrid.
            dgvAuthorType.DataSource = tblAuthorType;

        private DataTable PopulateDataSet(SqlConnection cnErasmus)
        {
            string strAuthorTypeSelectQuery = "SELECT AuthType FROM AuthorType";
            using (cnErasmus)
            {
                using (SqlCommand cmSelectCommand = new SqlCommand(strAuthorTypeSelectQuery, cnErasmus))

                        tblAuthorType.Load(theReader);
                        CloseConnection(cnErasmus);
                    }
                }
            }
