XML related in VB.Net

ddspliting

We have different classes in System.Xml namespace in VB.net like XmlWriter and XmlReader... with the help of them we can retrieve different information from xml document. Is there any way to manipulate controls like textboxes, checkboxes ,radio and submitting buttons? like sending some data to a textbox or getting data which is linked with Submit buttons etc?

Your question is kind of basic sounding, can you give a specific example of what you are trying to do?

a website shows result of some entry test conducted but you can access it only by the userID, (a number). It has just a textbox and a submit button. you enter the userID and submit it and the data is displayed to you ! like ID NAME Marks obtained Percentage in that format! Now i want the entire result! I know that students were from id number 1 to 10,000! so in a loop i enter the id and retrieve the info linked with that id that is a student's result and I SAVE IT somewhere in a file like ms excel file or a word file. Its not something illegal cuz i can sit and start entering IDs and writing down the result and so on but that ll be too dumb! i need all the result by an auto way(though it ll still take a bit time, hours maybe ) . If any other legal way you ppl know than tell me...

Firstly, i don't care if its illegal or not. But you do sound guilty :cool:=) Really though, you will need to use the WebRequest and WebResponse classes to programatically make requests and recieve responses to/from the site. Each response will need to be parsed so you get only the data you care about (no HTML tags, etc), and then you can save the result. There are a bunch of ways to do this, and a few dozen primers on using WebRequest, etc. Be Careful not to make it too efficient. If you loop 10K times in a few minutes you are doing the same as a Denial of Service attack and will either get in REAL trouble, or your IP blacklisted from the site. Wait a few seconds (10-15) between each request to simulate a human use and let it run over night.
