Inserting Captcha Image To Web Form?
Sep 14, 2011
i 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.

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?

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...

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.

Some sites have captcha images when you sign up for them. I want to take that captcha image and put it in an imagebox so that a person can put those characters in a textbox and then the form will submit the captcha text to the site.Example: My application has a webbrow ser which navigates to here from there i want the captcha image to be put in my other form which will have an picturebox.Code so far:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

having problems getting one of 2 pictures displayed when I run the program. In a whole, this is a coin tossing program that, after the toss button is pushed, is supposed to show either a coin heads or tails image while also displaying True or False for heads or tails respectively. Additionally, a running tally of how many times heads and tails is displayed.The main issue right now is that when I press the toss button, no image is displayed, but True or False is displayed as well as the running number. After checking, running numbers correspond with the T/F results. The secondary issue is that a running tally is displayed, but instead of it being in a single or double digit increasing format, it shows up as 0011122223345666 as you keep pushing the toss button. I've researched books and the web to find out where I'm going wrong and to get more clarification on why it's not showing, but I haven't been able to decisive.
Public Class Form1
Dim randomObject As New Random()
Dim headscount As Integer
Dim tailscount As Integer

I am building an application using vb.net with sql server for a small company which requirs me to create reports that contain images. In my application I use microsoft report (rdlc) and I don't using any data source wizard, I just add empty datasets and bound them from sql data when the application loading. By doing this, I want to retrieve images from my sql field and display them in my reports. I've tried to drop an image control from the report items into my report, match its value with an image field in my dataset, select database source and choose a appropriate MIME format for it but it doesn't work.
