I have a program that regularly checks if there is certain text in a rich textbox then changes that text's background color. Is it possible that I could create an XML file that contains child nodes for the text, and properties for what color to change that text to?

I was gonna ask how to check if a string contained only letters, but i have read up a bit on regex and gotten it to work. At least i understand what ^+$ does now. Do you think this is a good way to check the string?Also, newbiequestion here: What is the difference between theese two code-blocks. What is the preferred method? Does importing only add an alias, or does it "load" more code than i need. Does it make my code depend on some "library" i need to bundle with the application later? Is there any difference whatsoev

I am trying to create a simple program that logs in to a site using a WebBrowser, and it does it fine, but I want it to check if it actually logs in (correct details have been put in) and return the result to the program, I figured it would be possible to search for text on the page after submitting the login to see if it was successful or if it failed. How would I search for text on the page? My current code is this: [Code]

seeing that my last thread was not answered i made a new specific one....This is real simple:How can I add spell check to a rich text box?Background information:I built most of my application and I dont want to use wpf rich text boxes because then my code is not compatible. I could use MS Word but it ruins my app up(idk why but anyways i dont want to use becuz then the user has to have word).......Well I could also accept third party spell checks(which are free)

so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.

Might be a simple question but i was just wondering how you can validate a text box to check if it has any symbols in it? I've stopped my program from accepting integers but i don't know how to stop symbols like $, ^ & etc. All i want is letters.

I'm struggling with my computing coursework in college and I though My issue is simple but I can't get it right. I need to validate the text into a textbox and check that it contains ONLY alphanumeric characters, but it MUST contain both, not either numeric or alphabetic, but some of each.The textbox should store information about a Street address, that's why both the street Name and the property Number have to be input. Spaces " " and points "." should also be allowed.If it helps, something like "12" or "St. Davis Street" should NOT pass the validation checks, whereas "St. Davis Street 12" will do.I would like to get it done with regular expression as I've been using them throughout my work, but I don't mind other solutions.I'm using Visual Studio 2010 Professional, 4.0 framework and Visual Basic.

I have two large text files (about 1.8 GB each encoded in UTF-8). And I want to check if the content of both files are 100% same. If there is single character difference then it is considered not same, i.e. both files are different. How do I do that? So my question is: How to check if 2 large text files content are 100% same?

First how do I check if each listbox item in a listbox contains an expression (Regardless of how many items there are in the listbox) and secondly how would I replace that with text that I want
So, if the First item in the listbox contained "Http%$$" then how would I change that to "Http:" without affecting the rest of the text in the item
Here is the code I have so far
