View 1 Replies"WebClient Does Not Support Concurrent I/O Operations."
Mar 23, 2010I have some code that downloads a list of files from an array or URLs. It downloads fine, but I keep getting the following error between each download.
"WebClient does not support concurrent I/O operations."
To me that means I can't download more that one file at a time. If so how can I get the code to continue only when the download is complete.
If Compile A VB6 App On Win7 - ADODB.Connection Errors With "Class Does Not Support Automation Or Does Not Support Expected Interface"
Apr 28, 2011I compiled some VB6 code on my Win7 x64 machine and the result .exe will not run correctly on any other machine. VB6 code is just a new template .exe file with one button, a reference to "Microsoft ActiveX Data Objects 2.6 Library" and the following code in the button press event: Dim db Set db = New ADODB.Connection It runs correctly on my machine, but no others (even other Win7 x64 machines) (Update: I found TWO other users where it runs and one of them is Jeff Atwood!, but most machines have the same problem)

View 1 RepliesForms That Support Multiple Resolution
Oct 20, 2009I have this program, where the main (one and only, "ControlBox" set to "false" and "FormBorderStyle" set to "none") form will fill up the whole monitor. It wasn't set to "WindowState" = "Maximized", but rather I have it designed to fit on the resolution of the target monitor's resolution size. It is set to run on 1920 x 1080 size. Hence I have all the layout and child controls laid out nicely.Right now, I was thinking, what if I wanted to have my program fit snuggly (or nicely) into the target monitor's resolution, varying from 800x600, 1024x768, 1440x900 and such.What would be the best approach? Make multiple copies of the form in designer, lay out those controls, then create a centralized class file that sort of integrates all the methods that were existing in the original form, so that the rest of the form would be sharing it as well.
Or would I make only 1 form and do all the layout adjustment on runtime and having the hassle and pain of going through it? I have 1 main problem though, there's this logo which stuck on the top left portion of the form, which currently just fit nicely on this 1920 x 1080's form. I wonder what would happens if I size it on runtime.

View 2 RepliesVS 2010 - Add Support For Unrecognized Files To OpenFileDialog?
Mar 21, 2011I am working on a project which use files with a .HRZ extension. These are image files with a simple red, green, blue, red, green, blue structure. There is no header of any kind. I know how to display these files in a picturebox or convert them to a bitmap, but of course Windows 7 does NOT know what they are, so just shows a blank icon in the OpenFileDialog. How easy would it be for me to add support for this file format to Windows and/or the OpenFileDialog so I can show a thumbnail of each file? I can create my own file browser but I would really like to use the OpenFileDialog if at all possible.

Best Way For Concurrent HTTP Connections?
Apr 22, 2010I need to download a bunch of pages from a web server, ie. spidering. I know that servers are typically configured to only allow a couple of concurrent connections from a given IP, but that would already halve the total time to run the script instead of downloading one page at a time.

Apr 24, 2010I want to use System.Net.Mail.SendAync in an ASP.NET MVC2 application. I see that it throws an InvalidOperationException if there is already a SendAsync call in progress.

Asp.net - Implement Security Trimming With A Website With Multiple Folders And Multiple Web.config Files?
Jun 18, 2012I have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one
Handle Concurrent File Access With A Filestream/streamwriter?
Dec 10, 2009I am writing an audit file that is writing the username, time, and the old/changed values of several variables in the application for each user when they use my application. It is using a FileStream and StreamWriter to access the audit file. All audits for each user will be written to the same file. The issue is that when two users are updating this audit file at the same time, the "old value" of each of the variable is mixing up between the users.
Dim fs As FileStream
Dim w As StreamWriter
Public Sub WriteAudit(ByVal filename As String, ByVal username As String, ByVal oldAddress As String, ByVal newAddress As String, ByVal oldCity As String, ByVal newCity As String)
[code]....
This lives in an AuditLogger class, which is referenced via an instance variable (re-allocated each time the function is accessed).
Amend A List Box At Runtime?
Feb 24, 2010i have been trying to work out how to modify a list box at run time ( i.e add in the detail when some presses a button ).I found some code in a sample program, which I thought I understood, but when a cut and pasted this code into my program, it didn't work as expected.The code which I cut and pasted was
Me.resultsView.Columns.Add("Match", CType(Me.resultsView.Width / 2, Integer))
Me.resultsView.Columns.Add("Position", CType(Me.resultsView.Width / 4, Integer))
Me.resultsView.Columns.Add("Length", CType(Me.resultsView.Width / 4, Integer))
[code]....
Obviously the top few line are meant to be column headers. Seem simple enough but they don't work in my program, I get no column headers.
When I run the program and pressed the command button, the only thing that appeared in the listview box was the word "This". When i pressed the command button again there was another instance of the word "This" appearing next to the original. The same thing happened the next time I pressed the command button.

Automatically Amend File Name?
Apr 21, 2009My.Computer.FileSystem.MoveFile to move logs of a command line application to the directory that I want.The problem I'm having is that, if the file already exists, the program errors out. Which makes since.I could just use conditional logic to replace or rename the file if it exists. The problem with the former is that I need to keep all of the logs and the problem with the latter is that, without knowing how many files could exist, I wouldn't know when to stop renaming files.If I knew that there were only going to be 5 files, then I could work with it. But since there probably won't be a finite amount of files, I need something automatically amend the new log to another name. For example, if I had "Test", then the log would amend the next file Test1 and so on.

Asp.net - Increasing Max Concurrent Connections For Web Service In IIS7 (load Testing)?
Mar 29, 2012I'm trying to write a simple load tester for one of our web services, which is served through IIS7. I'm launching a load of threads (as Tasks) that call the web service as a Web Reference.Despite the threads all starting, only 2 concurrent connections from the app can be handled by the web service. I'm aware that by specification simultaneous connections are limited to 2 per user. For the sake of this load tester, which I guess is one user, I would like to open many simultaneous connections.I have tried to add the following to the web.config of the web service.
<system.net>
<connectionManagement>
<add address="*" maxconnection="40"/>
</connectionManagement>
</system.net>
My setup is as follows:
The web service is located at [URL], where MyWebServiceApp is configured as an application.The webmethod can be viewed as something trivial that simply waits for, say, 20 seconds before returning a response (making it easy to see that only 2 connections are open at any one time).The simplest form of the load tester code is ass follows:
Imports System.Threading.Tasks
Module SuperBasicLoadTester
Sub Main()
[code]....
I've tried pointing other load testing software (e.g. soapUI) at the web service and have observed the same issue.
Edits: I should add that the web service box is running Windows 2008 R2.Also I have run SoapUI and my loadtester simultaneously and each is only able to request 2 connections each (i.e. 4 in total).
