We're making a project named personal digital library. It works like an automatic file organizer, which organizes files accdg to different topics, which falls under document categorization. The problem is we don't know what algorithm will be used in our project, we're using VB.NET 2008. Another is do we need to create a database to store the files to be organized?
View 5 RepliesI need to:
1) Read a CSV file,
2) Put the data in a list object that I can sort,
3) and populate a few GridView controls on a form,
4) Write my sorted list to an excel file, which I've never done.
I'd like to create a formatted summary table that would look organized when opened in Excel. Who is best person/ or place to ask about that?
I want to create an application which acts like a file cabinet, where in i can store all my files viz. xls,doc,msg. So that i do not have to look for my files in hard drive, i can open an application and retrieve it from there.My application will be a standalone application whose data is stored on the location i mention in the application.Is it possible to build an application like this.
View 6 RepliesI have a process that's going to initially generate 3-4 million PDF files, and continue at the rate of 80K/day. They'll be pretty small (50K) each, but what I'm worried about is how to manage the total mass of files I'm generating for easy lookup. Some details:
I'll have some other steps to run once a file have been generated, and there will be a few servers participating, so I'll need to watch for files as they're generated.Once generated, the files will be available though a lookup process I've written. Essentially, I'll need to pull them based on an order number, which is unique per file.At any time, an existing order number may be resubmitted, and the generated file will need to overwrite the original copy.
Originally, I had planned to write these files all to a single directory on a NAS, but I realize this might not be a good idea, since there are millions of them and Windows might not handle a million-file-lookup very gracefully. I'm looking for some advice:
Is a single folder okay? The files will never be listed - they'll only be retrieved using a System.IO.File with a filename I've already determined.If I do a folder, can I watch for new files with a System.IO.DirectoryWatcher, even with that many files, or will it start to become sluggish with that many files?Should they be stored as BLOBs in a SQL Server database instead? Since I'll need to retrieve them by a reference value, maybe this makes more sense.
i've got a free mysql database online hosted by 000webhost, i'm just wondering if i could connect to the mysql database, and if so what would the connectionstring be like? when i connect using php its something like this: new mysqli("mysql13.000webhost.com", "user", "password", "database1"), how do i translate this into a vb connection string, i can't decide what to put as the data source [code]if there's no way to connect, is there anyway for me to create an application that can store and access database online?

View 3 RepliesTo improve performance, when one has many files to readwrite it is better to save them in smallergroup in different folders. Is there a magic number over which it is better to start splitting the folder? for example below "10.000" (invented number) files can be stored in one single folder, while above that it is better to start storing files in multiple folders.
View 16 Replies"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?

I'm doing a project where we are re-creating a very old system.The client wants the same base functionality and some improvements.One of the things I'm currently working on is the note-system. These are used as flags of some sort, but are also used as a comment field for some products or client profiles.In the old system you could write the text and save it like you would get in a .txt file. They want the new one to be able to do word formatting such as:
Different font sizes (Only some parts of the text)
Different font colours (Only some parts of the text)
Underlining of words
Bolding
Italics
Tab-spaces
Those are the specs they want. What I need to know is the following:
1) How do I do that?
2) Currently they store all these files on the server as text files and the database have paths that refers to each file. I want to be able to save a text file with that formatting to the HDD of the server like in the old system.
3) If possible I would like to save that text to the database with the formatting.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --

View 3 RepliesSome time ago in VB6, I wrote a recipe program that basically stores all the recipes as text files. I was going to rewrite it in .NET and use an Access DB. I figured this would help in searching and other things, ratings, etc. But I'm a little stuck. I don't know if:
a) I can or should store all the text files in the DB
b) convert the text files to some other file format
I can already use GetFiles with a mask to search the filenames, not sure if I need or want full text search. So, should I flush the DB idea or how to move forward? I really don't want to use SQL, but if that's the way to go then...
I'm writing an application that will be used to generate reports from a database and I want to have several predefined reports/queries built in but also offer the user the option to create their own query and be able to save it and run it whenever they want without having to set the query up again each time.
So I figured I would just store the query parameters in an XML file for the ones that a user has created themselves and I would store these XML files (one for each query) in the user's Application Data folder.
I'm wondering what I should do with the built in queries though (bear in mind that the parameters of these built in queries should not be configurable). As I see it, these are my options:
1. Have the query parameters hard coded in the application
2. Store the query parameters in XML files in the location where the app is stored (ie Program Files) - the installer would create these files when the app is installed
3. Store the query parameters in XML files in the user's Application Data folder with any queries they have created themselves.
I'm leaning towards option 2 for the following reasons: All queries (user defined or predefined) would then be in the exact same format and the program could then run them all in the exact same way. Option 1 would mean I would have to release a new version of the application if I ever wanted to change these parameters. Option 3 would mean that the program would have to create the XML files each time it was launched by a new user so it would be a bit pointless and the values for the parameters would still have to be hard coded in the application so that it could create the files correctly.

I'm writing a program that reads randomized test questions from a text file. The text file includes information about how to set up the screen including which pictures, videos or buttons etc. to show for each question. The user responds to the questions and another text file is created logging the results. would it be better to read in all the data from the text file into an array to work with during the test, or should I just read the questions one at a time keeping the text file open while the user responds. The amount of data that would be read into an array for an average test would be about 200 lines which range from a single character to 20 sentences (whose length would of course vary).
View 5 RepliesI have an ASP.NET application (vb.net codebehind) that has serious performance problems because of its storage of TIFF files in one server share. There are over a million .TIF files there now! The application tracks the scanned images of property with a corresponding row in an Oracle database table. We have this idea that it might be better to store the images themselves in a new Oracle table.
The alternative solution we are thinking of is to split up the server share into multiple folders by State (an OH folder, a WV folder, a VA folder, etc.) Seems like the database option might make more sense long-term, but how do we do it? Can a TIFF be stored in a BLOB column and then extracted back into TIFF format using .NET?
As I'm working with some image files for my project, where should I store it ?I mean, they will be displayed frequently to the user. What I do currently is store in the app directory and when needed, I use:
vb.net
PictureBox1.Image=New Bitmap(Application.StartupPath & "ImageName.png"
For some background images, I used to set it at design time. That is, selecting the image needed using the Image property and never changes it at runtime.So, what will be best place to store it efficiently.
