I have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....

i have been coding for years, but never integrated XML. So I guess I'm a newbie. I have inserted an XSD file in my project, ARequest.xsd. I created a folder in my project called XML just to organize things, so this file ARequest.xsd, is in this folder.
Now I have a form that displays data from a database that has the same fields that are in this XSD file. Can I load the XSD file into my Windows Form, load the elements from the data on the windows form and then create an XML file then send it? If so how? Any code snippets would be helpful. Now I do know how to create the XML file, we'll call it Test as

I need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"

I've had a vb.net application for quite a while. Today, when I tried to load a form (one of many in the app) in Design mode, I got the error: "Could not load file or assembly 'Interop.MSMAPI, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." This form is the only form using msmapi, and the only one that won't load in Design mode.I can edit the form's code, run the application, and deploy the application. But I cannot access this form in Design mode. It's been a few months months since I've opened this form in Design mode, but it worked last time I tried it.
