Asp.net - IHttpHandler For Images Producing A Stackoverflow In IE?
Jun 24, 2009I have a directory of images that reside outside the context of my web application that I need to serve to the user. Currently I'm using an IHttpHandler to serve the images and using some javascript to navigate through a set of images (the navigation is primitive for now). I followed examples for using IHttpHandler to serve images closely but when I view the images in firefox the browser hangs and when I view in IE I get a "Stack overflow at line: 0".
Code for the IHttpHandler
Public Class ShowImage : Implements IHttpHandler
Public Sub ProcessRequest(ByVal context As HttpContext) _
Implements IHttpHandler.ProcessRequest

Producing Array Of Unique Values
Mar 17, 2012I need to create an array, then iterate through a string, adding the string value to the array only is it does not already exist, to produce an array of unique values. The issue I am having is with the array.length operation - on a array that is nothing I am unable to retrieve the array length (0), as such I am unable to redimensionalise the array to be array length (must be array length as arrays are indexed from 0), providing me the ability to add the new value to the array and then continue the loop until all values have been checked to see if they exist within the array (using contains) and the value contain only unique values..

Text Formatting Isn't Producing Expected Results
Oct 4, 2011I'm trying to make a simple tool to format SQL code so that I can use it in VB.When I put in the following:
USE master
CREATE DATABASE netGuest
GO
I get...
"USE master" & vbCrLf & _"
CREATE DATABASE netGuest" & vbCrLf & _"
GO" & vbCrLf & _"
So it almost works. Really the only thing not working is that the lines are ending with the " rather than starting with them.Here's my code:
Protected Sub btnConvert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnConvert.Click
If txtVB.Text IsNot Nothing Then : txtVB.Text = "" : End If
Dim input() As String = txtSQL.Text.Split(vbCrLf)

VS 2008 Producing A Log From A Command Line That Does Not Produce One
Sep 22, 2009I need to parse a log file from some information provided via an external command line application. The problem is that the command line app doesn't produce its on logs.

If there is only one item in the database, then this code works. If there is more than one record then the error is produced that it is trying to produce duplicate values. This is down to the Primary key in my database which is the only thing that cannot have duplicate values. However, when I remove the primary key it has the predictable problem that it goes crazy and does weird things.
VS2008 Move To W7 - Compiler Producing Different Size Install File?
Nov 29, 2009I'm currently moving over to W7 from Vista I've moved my source over (amazingly hassle free), but the Build option on my installer in my solution produces a different size (200K+) setup.exe file.
Initial question are:
1) Is there a log file I can compare betwen the two builds (V7 -v- Vista)
2) I thought that any compiler settings would 'follow the solution' Is this so?

C# - Lambda Expression: CS To .Net?
Aug 24, 2011I am dumb founded at this statement....maybe its just too many hours/days of doing C# to VB.Net conversion but i am drawing a blank on this conversion.
List<string> sColors = new List<string>(this.CustomPaletteValues.Split(','));
try {
List<Color> colors = sColors.ConvertAll<Color>(s => (Color)(new ColorConverter().ConvertFromString(s)));
What i have so far:
Dim colors As List(Of Color) = sColors.ConvertAll(Of Color)(....)
As you can see its the content of the lambda that i am hitting a brick wall with.
