I need some guidance on the best way to proceed with searching a file content. I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file. These files contain information that is produced from another application and therefore I am unable to change the format of the file.
This file contains information that I want the user to be able to be able to enter search criteria in a form that then searches this file and returns information. The individual information is split into sections of data and this is defined by the section start label lbl{ and the end label }} Therefore the below information highlighted in bold is an individual section
CODE:
Now comes the hard bit, in the bold section above you will notice that there is some text Equip no: P-102B I want the user to be able to enter in a form *102B* and for it to return -32768 21 12 0 which is after lbl{ and before text
Now obviously I could loop through the whole file to do this, however I am very concerned about RAM usage and also the time it will take to do this. Obviously the user could use this search option over and over again and therefore we would be searching the same file over and over again.
What I am wondering is if anyone has an idea on how best to do this?
One of my thoughts was to read the file once and output the content in an Access Database table and then use SQL to get the information? However would the user require Access on there machine to be able to do create the database or could I just ship a blank Access database with my app and then copy this and populate? Also I am not sure if Access is the best database, obviously I don't want people to have to use Oracle of SQL as this would require server configuration etc. but are there better free databases out there?

I have to generate an XML file from several database tables. I could use the WriteXml method of the DataSet to do it, but the database tables are really huge and I can't add all those tables in the DataSet at the same time or it may cause a problem because of the big amount of memory used. Then I decided to use the DataTable's WriteXml method and save table after table, but the the generated file only stores the information of the last DataTable.WriteXml's call. How can I preserve the previous XML data when adding all that information?
I have a textbox on a form that is set to allow dragdrop operations from txt files.Basically you drag a .txt file onto the txtbox, the content of the text file is displayed in the textbox.All is working fine, however after the textfile is displayed in the textbox, the text box text is for some reason is highlighted.I don't want the text to be highlighted (or selected) after it's being displayed on the textbox.Second issue, after I close the file that I dragged, for some reason even if I didn't make any changes to the file, it is acting as if the file has changed.In another words, if I open a text file using my MenuItem Open item, and if I do not change the file, If I close the file it's fine it closes.However, if I close a file that I draged into the text box and then close the file without changing anything in it, the stringcompare function is telling me that the file has changed... I can't understand why.

what i would like is if the passwords do not match in both maskedtextboxes for the system to throw out a message saying passwords do not match please try again..which then clears previous content and requires the user to enter details again. once details are correct and system commits the new user details to the table and throws up a confirmation message.
