  • VB - Convert Web Site to Web Application

    - by Dave
    Hi This is my first time doing VB :-) I've inherited a web site, which I've converted into a web application in VS2008. The conversion has worked for everything except a Gallery control. The compile error I'm getting is: Type 'Gallery' is not defined in file: gallery_oct07.aspx.designer.vb Option Strict On Option Explicit On Partial Public Class gallery_oct07 '''<summary> '''Gallery1 control. '''</summary> '''<remarks> '''Auto-generated field. '''To modify move field declaration from designer file to code-behind file. '''</remarks> Protected WithEvents Gallery1 As Global.Gallery End Class with squiggly lines under Global.Gallery. The gallery_oct07.aspx.vb is: Partial Class gallery_oct07 Inherits System.Web.UI.Page End Class Gallery.ascx is: <%@ Control Language="C#" AutoEventWireup="true" Codebehind="Gallery.ascx.cs" Inherits="WebApplication1.Gallery"%> <asp:Repeater runat="server" ID="rptGallery"> <HeaderTemplate> <ul class='<%#CssClass%>'> </HeaderTemplate> <ItemTemplate> <li><a href='<%#ImageFolder + Eval("Name") %>' class="thickbox" rel="gallery"><img src='<%#ImageFolder + "thumb/" + Eval("Name") %>' /></a></li> </ItemTemplate> <FooterTemplate> </ul></FooterTemplate> </asp:Repeater> and the code behind is: using System; using System.IO; namespace WebApplication1 { public partial class Gallery : System.Web.UI.UserControl { public string _ImageFolder; public string ImageFolder { get { return _ImageFolder; } set { _ImageFolder = value; } } private string _cssClass = "gallery"; public string CssClass { get { return _cssClass; } set { _cssClass = value; } } protected void Page_Load(object sender, EventArgs e) { DirectoryInfo dir = new DirectoryInfo(MapPath(ImageFolder)); FileInfo[] images = dir.GetFiles("*.jpg"); rptGallery.DataSource = images; rptGallery.DataBind(); } protected void Page_PreRender(object sender, EventArgs e) { } } } The feels like a namespace issue.. My project namespace is WebApplication1. Cheers!

  • Try catch finally blocks.. do i still need them?

    - by Phil
    I am handling errors via my global.asax in this method: Dim CurrentException As Exception CurrentException = Server.GetLastError() Dim LogFilePath As String = Server.MapPath("~/Error/" & DateTime.Now.ToString("dd-MM-yy.HH.mm") & ".txt") Dim sw As System.IO.StreamWriter = New System.IO.StreamWriter(LogFilePath) sw.WriteLine(DateTime.Now.ToString) sw.WriteLine(CurrentException.ToString()) sw.Close() In my code I currently have no other error handling. Should I still insert try, catch, finally blocks? Thanks.

  • What "exotic" language feature do you use every day?

    - by fmark
    For most programmers using procedural or object-oriented languages there is a language-feature lowest common denominator: variables, procedures, standard control structures, and classes. However, almost all languages add features on top of this. Recent C# versions have LINQ and delegates. C++ has template metaprogramming. Java has annotations. What features such as these do you use every day?

  • OCCI createEnvironment Blocks My Thread

    - by sahs
    Hello, I'm writing a multi-threaded application, where there is a main thread which distributes tasks to the worker threads. According to the task, a worker thread creates a connection, by using a global occi environment. When a worker thread completes its task, it closes the connection (I'm sure, there is no exception thrown while termination). My problem is that after a while(sometimes 5 mins, sometimes 5 hours) the threads cannot get connection from the environment, and they get blocked there. What can be the problem?

  • C# Multi-Comparisons possible?

    - by Iggy Ma
    is it possible in some way to compare multiple variables to one constant in a if statement? It would be very helpful if instead of if ( col.Name != "Organization" && col.Name != "Contacts" && col.Name != "Orders" ) { } I could just say if ( col.Name != "Organization" || "Contacts" || "Orders" ) { } And I know I could use a list but in some instances I dont want to... Thanks!

  • Handling exceptions raised in observers

    - by sparky
    I have a Rails (2.3.5) application where there are many groups, and each Group has_many People. I have a Group edit form where users can create new people. When a new person is created, they are sent an email (the email address is user entered on the form). This is accomplished with an observer on the Person model. The problem comes when ActionMailer throws an exception - for example if the domain does not exist. Clearly that cannot be weeded out with a validation. There would seem to be 2 ways to deal with this: A begin...rescue...end block in the observer around the mailer. The problem with this is that the only way to pass any feedback to the user would be to set a global variable - as the observer is out of the MVC flow, I can't even set a flash[:error] there. A rescue_from in the Groups controller. This works fine, but has 2 problems. Firstly, there is no way to know which person threw the exception (all I can get is the 503 exception, no way to know which person caused the problem). This would be useful information to be able to pass back to the user - at the moment, there is no way for me to let them know which email address is the problem - at the moment, I just have to chuck the lot back at them, and issue an unhelpful message saying that one of them is not correct. Secondly (and to a certain extent this make the first point moot) it seems that it is necessary to call a render in the rescue_from, or it dies with a rather bizarre "can't convert Array into String" error from webbrick, with no stack trace & nothing in the log. Thus, I have to throw it back to the user when I come across the first error and have to stop processing the rest of the emails. Neither of the solutions are optimal. It would seem that the only way to get Rails to do what I want is option 1, and loathsome global variables. This would also rely on Rails being single threaded. Can anyone suggest a better solution to this problem?

  • C: Random Number Generation - What (If Anything) Is Wrong With This

    - by raoulcousins
    For a simple simulation in C, I need to generate exponential random variables. I remember reading somewhere (but I can't find it now, and I don't remember why) that using the rand() function to generate random integers in a fixed range would generate non-uniformly distributed integers. Because of this, I'm wondering if this code might have a similar problem: //generate u ~ U[0,1] u = ( (double)rand() / ((double)(RAND_MAX)); //inverse of exponential CDF to get exponential random variable expon = -log(1-u) * mean; Thank you!

  • When I really need to use [NSThread sleepForTimeInterval:1];

    - by Timbo
    Hi there, I have a program that needs to use sleep. Like really needs to. In lieu of spending ages explaining why, suffice to say that it needs it. Now I'm told to split off my code into a separate thread if it requires sleep so I don't lose interface responsiveness, so I've started learning how to use NSThread. I've created a brand new program that is conceptual so to solve the issue for this example will help me in my real program. Short story is I have a class, it has instance variables and I need a loop with a sleep to be depended on the value of that instance variable. Here's what I've put together anyway, your help is very much appreciated :) Cheers Tim /// Start Test1ViewController.h /// #import <UIKit/UIKit.h> @interface Test1ViewController : UIViewController { UILabel* label; } @property (assign) IBOutlet UILabel *label; @end /// End Test1ViewController.h /// /// Start Test1ViewController.m /// #import "Test1ViewController.h" #import "MyClass.h" @implementation Test1ViewController @synthesize label; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; label.text = @"1"; [NSThread detachNewThreadSelector:@selector(backgroundProcess) toTarget:self withObject:nil]; } - (void)backgroundProcess { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // Create an instance of a class that will eventually store a whole load of variables MyClass *aMyClassInstance = [MyClass new]; [aMyClassInstance createMyClassInstance:(@"Timbo")]; while (aMyClassInstance.myVariable--) { NSLog(@"blah = %i",aMyClassInstance.myVariable); label.text = [NSString stringWithFormat:@"blah = %d", aMyClassInstance.myVariable]; //how do I pass the new value out to the updateLabel method, or reference aMyClassInstance.myVariable? [self performSelectorOnMainThread:@selector(updateLabel) withObject:nil waitUntilDone:NO]; //the sleeping of the thread is absolutely mandatory and must be worked around. The whole point of using NSThread is so I can have sleeps [NSThread sleepForTimeInterval:1]; } [pool release]; } - (void)updateLabel {label.text = [NSString stringWithFormat:@"blah = %d", aMyClassInstance.myVariable]; // be nice if i could } - (void)didReceiveMemoryWarning {[super didReceiveMemoryWarning];} - (void)viewDidUnload {} - (void)dealloc {[super dealloc];} @end /// End Test1ViewController.m /// /// Start MyClass.h /// #import <Foundation/Foundation.h> @interface MyClass : NSObject { NSString* name; int myVariable; } @property int myVariable; @property (assign) NSString *name; - (void) createMyClassInstance: (NSString*)withName; - (int) changeVariable: (int)toAmount; @end /// End MyClass.h /// /// Start MyClass.h /// #import "MyClass.h" @implementation MyClass @synthesize name, myVariable; - (void) createMyClassInstance: (NSString*)withName{ name = withName; myVariable = 10; } - (int) changeVariable: (int)toAmount{ myVariable = toAmount; return toAmount; } @end /// End MyClass.h ///

  • SharePoint and Log4Net

    - by Nico
    I'm looking for best practices to integrate log4net to SharePoint for web request, feature activation and all timer stuff. I have several subprojects in my farm, and I would like to have only one Log4Net.config file. [Edit] Not only I need to configure log4net for the web application, which is easy to do (I use global.asax, and a log4net.config file, so I can modify log settings withtout reloading the webapp), but I also need to log asynchronous events: Event Handler (like ItemAdded) Timer Jobs ...

  • code style for private methods in c#

    - by illdev
    I just found out, that it seems a common pattern to user UpperFirstLetterPascalCase() for private methods. I for myself, find this completely inconsistent with naming rules of private instance fields and variables and I find it difficult to read/debug, too. I would want to ask, why using a first upper letter for methods could be a better choice than a first lower (doThis())? Just out of curiosity...
