I have a feeling it is an easy one, but for the life of me i cant figure it out. My project at the moment is to grab content from a website and use it in some way (havent worked out this part yet, still trying to get the data).
Currently, i have grabbed the whole website and written it to a text file.. No dramas there. Then i read each line until i find a certain string... Again, no dramas. MY problem is; after reading and finding the certain string, i want the program to grab whatever "characters" there are until it reads a certain string again, and then put those characters into a string for later use.
so for example:
READ WEBSITE...
CREATE TXT FILE...

I have a fairly simple XML file that I just want to read the data from.
It has 3 levels, root, main section and items. There are no attributes. I want to go to the first main section by name, then read in all the items. The items all are named the same. I've seen this done before, so it should be ok. No writing will be done. Basically this is a static data file

I use an OLEDB connection to read from an excel database, and this loop to read in all of the data from each of the columns
While reader.Read() For i As Integer = 0 To reader.FieldCount - 1 temp = reader(i).ToString + ControlChars.Tab output_file.Write(temp)
[code]....
Some of the columns contain date information, which are read in fine (usually as a string "2/20/2011" or so), but the headers of those columns are read in as a blank "". The headers for all the other columns read in fine, but not for the date containing columns.

Its just an example and not for a grammar corection program. What i want to do is detect what was said and alter it acordingly. I presume this would come under string manipulation but i cant find any details on this.

I have a text file (CSV) approx 100k lines (8Mb). I want to search the entire file for a particular string eg, "apple" and for all lines containing the string to be printed in a text box. have successfully done this using streamReader to parse the CSV and check each element against the search word eg. apple. This has proven to be very very slow and I have read that the "ReadAllLines" method is much faster.
How do I read all the text from a text file and save it as a string variable? For some reason I remembered it being something like this: IO.FromFile.ReadAllText("path") but thats not it.
