VS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?
Jul 24, 2011I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

View 2 RepliesExtract Specific Data From A Text File?
Feb 16, 2010Imports System.Globalization
Imports System.IO
Public Class Form1
[Code]....
I have found the above code from the net and it works fine as I would expect. I know this because I have added a put the String StoreFile into a text box and it worked. From what I understand about the code above is that we are reading the file test.txt until we reach the end of the file and we are storing it into a string.
What I would like to do is either:
1. Search the String StoreFile until I find the text of my choice, and then extract the characters around it. See attached txt file.
For example, if I wanted to search for MNAUSD in the attached txt file, I want to grab the values on the line (highlighted in blue) and make them available to my program and ignore everything else.
"MNAUSD",UNITED STATES,US $,M,1.558850,1,1.369850,1.113500,L
I know these files are comma delimited, but I would rather use a regular expressions if possible as I have other files that are not comma delimited, so it would be ideal if I have a regular expressions to handle the search and extract
OR
2. Search the File test.txt LINE BY LINE, until I reach my search text MNAUSD and then extract the same values as above.
Flat File Specific Data Extraction
Feb 25, 2010i have been searching the web for days and yet to find a clue on how to extract specific data from a flat file, i know how to extract all the data from flat file but not "specific data".
my problem now is that i need to extract a certain data out from a very very messy log file, what i need is to extract the decimal data right after "score=". it is in this format "score=1.938249".
for the decimal data right after "score", it is very random, there is no fix length to this. and also "score" does not fix in a specific position, it could be starting of the string or ending of the string of messy data.
just a peak on my messy data,
"time 20:34 17/1/2010 vlog=0 C:d7ad45f396850c532ef0ccf0da48d80di386peisgh437 ipint=98.1857991 score=1.78495 event@&1.13845"

Apr 29, 2010How would I use the BinaryWriter to append binary data to a file that is very large? Say a file that is 3GB in size.

If I were to enter a value that exceeds the size of an integer on my 32bit Windows XP system, which I believe is 2147483647 it will reject it right?
