Store TIFF Files In Oracle?
Nov 11, 2009
I 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?

I've a scenario where I've to move data from a Oracle Table to a SQL Server table. The column in Oracle is Timestamp(6) 6 being the precision. Now I cannot send the Oracle Data in string format. I pull the data straight from the Oracle Table, so cannot format it on oracle side. What I can do is format the data using VB6.Format to make it suitable for SQL Server DateTime. I'm doing this for Oracle Date to SQL Server Datetime

I'm trying to use my existing application to open tiff files for clients and staff in order to print or view the reports that we have scanned into our server. Unfortunately I have been unable to find a free, preferably open source library or wrapper for a library that will work in VB.NET running through Visual Studio 2005. Does anyone know of any open source/free implementations of this that I could adopt in my application?

To 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.

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've written a loading program that writes text files to our database. The text files are dumped by another system every 2 hours onto on a shared network drive at my work. Here's the problem though - the files don't have a date/time stamp within them. I've been getting the date for each file from the creation date. That works okay, but when I've written loading programs in the past, I like to move the loaded files into a folder called "Loaded Files". That way, I can quickly see visually how many files I've loaded vs how many have not be loaded.
The problem this time, is that if I were to move the file into another folder, the creation date changes...a lesson I learned when I copied all of the files into a directory on my C: for testing. They all had the same date/time stamp!My question is, what's the best way to handle this? I don't want to move the files after loading them if it alters their creation date. I mean, what if I have to go back and load one for some reason, the date will be lost forever. I also don't want to write something into the software that has to check a file each time before loading it to the database.

I am reading a csv file in to a datatable in vb.net and making a few checks and appending an extra column. I then want to perform a bulk insert using microsofts Oracle.DataAccess (no choice in this) to an Oracle database. what would be the best way to perform this as there is no bulkImport like in SQLserver.

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 --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I'm trying to store all my files into one file. I have quote huge file but the file stops at 194,000 KB and it doesn't save beyond that but the problem I've built says that the file has been saved. I would like to know if there is a way to go beyond this limit? And for the file to just keep getting bigger.

Some 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).

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.

I 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.

I 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.

How can i store unlimited multi-row strings without the need of extra files?Example: the user enter a multi-row string into a textbox and clicks save. Then the program should save that somewhere. And then the user enters another string and clicks save. And then there is a combobox where it can choose between those 2 strings to load.Can i save them in some sort of collection like My.Settings.Collection? Where each text also has a header.
