I am creating a fault tracker AKA issue tracker. It is going to be very simple in functionality. As of right now I am using a text file as a database for the end user to store current issues.
The reason for me using a text file is that I do not know much about database programming and I cannot find any simple examples in the same usage. My question is, is it really going to become a problem as more issues are added to this file and it becomes larger? I.E using up more resources, application getting slower etc?
If so, could anyone point me in the right direction to creating a simple database application. Most examples I have seen require ask to download their pre-made database. Although I would like for the program to create a database if one is not there.

I want to upload a text file to a table I have in my database. I have never done this kind of a thing so I don't have any clue. The column is in longblob.
View 10 RepliesI'm working on a project right now that basically prints a string to the field that has focus in internet explorer and there's quite a bit of user specified information that needs to load when the vb program loads. Should I use a text file to store and retrieve the settings or a database? I'm a new programmer and I don't really have a clear idea on when I should use a text file compared to a database or the registry to store info. Also, if I use a database like access 2007 for example, wouldn't an end user run into an exception if they don't have that software installed on their comp? Is there a universal database format? I've linked some screenshots of the prog if you want to get an idea of how much info I need to store.

I have a text file with some call records in it. Each call record states a line in that text file. And what I want to do is that parsing to database with a 100% success rate. Due to sometimes the SQL connection might get buggy or stop or w/e so it came to my mind that I should make some function or maybe a stored procedure to check whether the requested/selected or whole lines in that text file have been successfully added or not to the database. Let's assume I have 10 lines in a text file called "log.txt" like:
call line 1
call line 2
call line 3
call line 4
[code]....
And assuming that the SQL connection to the database got stuck somehow(buggy) and it stopped inserting those lines to their respectively columns. Let's say it parsed lines from 1-6 and it stopped there, that's where I need the app to tell me that it stopped and continue inserting immediately where it stopped at to the end from 6-10th line. What am I supposed to do? The smoothest way so that the processor doesn't get overwhelmed (in case there are like hundreds of thousands lines). And should it be written in SQL as a stored procedure or written as a function from VB side.Toolkit : Microsoft Visual Studio 2010 Ultimate - VB.Net language & Microsoft SQL Management Studio 2005 - SQL Database.

View 7 RepliesI am trying to import a text file to an access database in VB2008 express. The text file I am testing with is a csv file with 34,000 records. The problem is this takes 2 minutes to read through all this and write it to the database. The actual text file I will be using in production has over 800,000 records and this will take a ridiculous amount of time. I think I am doing something wrong. I have posted my code below. I am reading a record, parsing out the fields to an array, then creating an SQL statement to insert the record and executing it.
