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 have created an updater for our clients application. The way the updater works is to download all the updated files and store them in a temporary folder then check the file hashes. If everything is ok it will copy the files to the applications installation folder. Once this is been completed it will delete all the updated files in the temporary directory.
My problem: I am looking for a directory that will be available for XP, Vista, and Win7. I was thinking about the 'temp' directory.

View 7 RepliesBasically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string
Do Until Integer.TryParse(Console.ReadLine(), LastName) = False
Console.WriteLine("Invalid input, Please try again")
Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.
I am in the process of writing a win forms desktop app in VB.net that employs user data in the form of rich text, stored internally as an object and then serialised to an XML file for persistent storage purposes.
To create the user data (the application's "document" it might be called), I have written a seperate app that tries to be a word processor and then saves the text in my XML format that can then be opened and used in the main app.
Is there a way I can use Word to do this? Perhaps by writing an add-in or template? Just to clarify, the format of the rich text would just be a table, I then need to save this in my XML format, or save the text as my object then serialize it to file.

View 5 RepliesI have a favorites application which makes files corresponding with the favourites, but with the windows filesystem, I cannot create files with the characters: <> /\ : ? * ". This means that I cannot create favorites with HTTP: in them, which kind of ruins the point of having a favorites viewer. How I could convert the http: to another expression and save it, and then when the project loads make it into http: again. I have thought about using Regex to replace the expressions, but I do not know how to do that in a listbox.
Here is my code:

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."

View 5 RepliesI'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.
Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.

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.

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.
