I'm trying to figure out how to prompt a user to enter a captcha. Some programs out there have a little popup with the captcha image and a textbox, the user then enters the characters from the image and the captcha is solved by the user of the application. When I try to request the image directly, it gives me a different image than the one currently in the webbrowser control. Any ideas how I can create the pop up of this captcha image for the user to enter?
Note : . I'm looking for a way to prompt the user to enter a captcha from website.
I am supposed to create a program in my VB.net class to do the following:
1. Prompt the user to enter the beginning number and the ending number.
2. Find the sum of the even numbers between these two values, inclusive.
[Code]...
We are currently using for next statements in the class. I know how to prompt for and utilize the numbers that are input etc. My problem is the EVEN numbers part. I obviously have to determine if the number is even and then use a step value of 2 from there. But not sure how to determine if number is even or odd (guessing to use mod, but totally lost).
I am wounder if anyone might have a web site or no where I can find the information so I understand how to prompt the user to enter the beginning number and the ending number. And then to find the sum of the even number. Now does anyone know what a name convention is ? I have tried to look it up on the forums but cant find nothing on it.
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 working on adding a de-captcha into one of my programs but I can't seem to be able to grab the captcha from the web browser.I don't think I can just parse the URL and use webrequest to download it as it'll be a different string once it's reloaded.
I need to prompt the user to input a few key/value items.Instead of building a form with a bunch of label + textbox, I figured I could use a simple, unbound grid.
I know the ListView widget can be displayed as a grid, but it appears that some added code is needed to make it behave that way.If you've investigated the matter recently, which solution did you end up using?

I'm writing the following bits of code for a SaveFile Dialog box in Visual Basic 2010.NET. The code works well as the XLSX file is created and opens in Microsoft Excel. However, the problem that I am having is that if the program overwrites a file, the user is getting two prompts. One prompt is from the program's own SaveFile dialog confirming the choice. The other is from Microsoft Excel asking you the same. It's as if the program is running in the background. Does anyone know how I can write this code to save the file as an Excel file? [Code]

Is there any way to use a VB form to supply user credentials to the Runas command in command prompt? I basically need something exactly the same as the GUI for RunAs but just for Internet Explorer (yes I know you can right click and go RunAs but that cant be done in this case). So the user would open this VB form, type their username and password in, hit OK and it would open Internet Explorer with their credentials (they log in under a generic account used by many people).

It's probably the most basic of things, but all I can find is how to launch a program, and not with the interactions I desire. Any tips as to the terms to use to search for answers, or links to topics regarding questions similar to mine, would be very appreciated. I have a wealth of info to read through, but I could use your knowledge to save myself time.Here is what I am trying to do:
Use a Button (A) to Launch a Prompt where User Selects Directory Path to an executable Program. The Selection is to be Persistent after the initial selection (saved in a settings file i assume?), and the Selected Path (or just "programname.exe") is to be Displayed in a Text Field (B). Launch Selected and Indicated Program via a Launch Button (C)

But Im not sure whats suppose to go inbetween the speech marks.
