View 2 Repliesstore and retrieve image in a SQL Server database with vb.net.:Well, the application in vb.net seems to have a database which can accessed by the LAN computers so the SQL Server 2005 database allows remote computers to share its database once the other computer application requests database from the server.So, every other computer has to store and retrieve images in SQL Server 2005. For example, comp1 has to store images taken into the server and retrieve it like tableadapter.

View 4 RepliesAt the moment each Company on my website have 1 picture they can add to their profile.I save that image into the database.its their Company Logo.Now i want to allow them to add more pictures. Now i don't know if i must save it all in the database or save it in folders???? Reason why i think folders will be better is because there are so much nice articles with fancy silver light kinda features that i can use but all of them only cater for images saved in folders.And since i am not THAT good its hard for me to change the code to look at the database instead of the examples that uses folders for image retrieval.I would like to add something like this to my website (browsing through the images).Any code examples for me on how to do this when images are saved in the database? I am using ASP.NET with VB.net.

View 3 RepliesIf you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.

View 1 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 use AES encryption in my vb.net 2008 windows forms apps to ....
1. Store user passwords in sql server express database in encrypted form
2. decrypt the encrypted Sql server express connection string password on the fly when connecting to SQl Server over a vpn or direct to web based sql server database
3. decrypt the encrypted ftp site password on the fly when my application connects to my ftp site to upload client's database backups
The issue I have is that the secret key for the encryption / decryption is hard coded within the encryption/decryption functions. So anybody who decompiled my application would be able to generate the same encryption, as they would have the encryption secret key How can you hide the encryption secret key so that if anybody decompiled my app they could not reproduce the decryption function
