I have a question about how to get a button to check for a textbox contents, and then compare that with data in my fairly simple database (It's meant as a login procedure).
Here's my database:
It has 2 values, 1 for the manager and 1 for the Admin
Here's my Login screen:
Now...
Everything works just fine, all the code is correct so all the buttons work. For the program i'm making, there's 3 types of users, 1 user who can only change how much money a customer owes the company, 1 user that can add new customers and other little things and one Admin who can change pin numbers and manage backups and stuff like that. For the last 2, i need pin-number/password protection obviously.
The user should enter the pin and then press ok, after which the ok button checks if the pin number the user entered, corresponds to either identifier 1 or 2 (5566 or 6655 for now) and if correct, show the user the next form.
I'm trying to write two regex's - you'll need to tell me if they're even possible. Both are based on VB.net syntax.
Regex 1:
The string I'm testing against -
Size on disk: 25,754,900,936 bytes
It has a handful of leading spaces, but the text is ALWAYS the same. I'm trying to extract out just the number (25,754,900,936).
I've tried a handful of regex's, but I can't get everything on one line. The commas are messing me up and returning multiple matches (For example, d+W+ gives me four matches, one for each set of numbers separated by commas.)
The best I've done is [0-9/,]* but that gives me 25 empty matches and one match (On match 19) of the number. I need this to match on match 1.

I've a situation where I am trying to extract a large number of URLs from a site, but the site which provides the URLs has an obstacle. Rather than the link directly to the site, they provide a link to an internal page, which automatically redirects me to the URL I need.
i.e.
<a href="www.StartingSite.com/outgoing/1234" ...> Example.com</a>
which passes me to an internal page, then automatically routes me to Example.com
I've suspected if I can do this, it would be through cookies.
Perhaps a little more work, I could create a page which calls each page, then I could acquire the URLs from my history, but my browser would crash for the # of URLs I'm extracting.
any means I could gather the end URL of this link?

To simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
