I'm making an image uploader for a site but sometimes a captcha from [URL] appears? Is there any code I can use so when the captcha appears, a box with the captcha image appears so I can manually solve it? I've seen some programs that do it so i know it can be done...

When you reach a captcha while creating accounts on some sites, is there code that would make the program pause and a message box pop up that would ask for input for the captcha code?

View 7 Repliesi have an aspx web form with vb code behind. the form is a simple input form with a table with textboxes and a submit button. i am looking to be able to insert a captcha image into the table with an entry textbox and check the value entered against the image on the submit button.
i have found various 'helpful' bits of code on the net to explain how to generate the image. but none of them explain exactly how/when the image would get generated, how you can insert the image onto the webform where you want it to be, or how you can check the text input against that image.
I made an email account today and out of curiosity I was wondering if this is possible. Is it? Has it ever been done before? How is it even possible? I mean, all that spam email I get, it must be generated emails doing that because even though I "mark as spam" it, I still get the same email but from another address.

I have a https site where i have to display images from a http source. To enable this i want to make a proxy, so i can display the image as:
src="https://mydomain/showimage.aspx?url=http://externalserver/image.jpg"
I can do this in Java, somthing like this:
Code:
InputStream in = new WebInputStream( url );
BrowserOutStream out = new BrowserOutStream();
while(in.read()){ out.write() };
in.close();
out.close();
Simple enough (although the code is simplified here). But i cant seem to find a proper example of the equivalent in vb .net. I am assuming i have to use System.Net.WebClient.OpenRead, but not sure where to go from there.
I want my program to grab any image on the site that the url starts with like lets say can I use wildcards on vb.net?[URL] like [a-z|A-Z|0-9] or something like that? The full url for a image smaple would be [URL]

View 1 RepliesI have an AsynchFileUpload on my page and for some reason when I try to use it to save the file to the server it falls. The control will allow me to select a file locally and it displays the local file path in its text box, BUT when I then click a button on my page which I am going to be using to submit all details then upload the page everything goes wrong and I get a Null Ref Exception from the AsynchFileUploader.

It seems that the filename is being lost somewhere after the button is clicked, or just never stored

View 3 RepliesIve got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with

View 16 RepliesI'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.
I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.
I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:
IDE: Visual Studio 2008
Server: Windows 2003 with IIS 6
Language: VB.NET 2.0
