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.

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.
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.
How do you store data in the access database and also to retrieve it? and also a search engine for the database?
View 1 RepliesI have a database table where the user marks files to be downloaded. Subsequently, I browse this table and need to create a fileList to pass to an ActiveX downloader. My routine works locally and on the server for ONLY the first file. I know my logic must be bad, but I cannot find it. All of these files are always in the same server directory which is as follows:
"D:inetpubvhostsWebSite.comsessionVideos"

View 4 RepliesAs 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 want to write a program using vb.net tht compares the name of a document on my desktop to the name of the document on the server. If they're the same then I'd like to retrieve it and have it replace the file I already have.
How can i do this? Does this mean that i have to write a web application cuz i hope not. I dont no anything about those. I am using that server for storage purposes only so i assumed that i didnt need a database for the name of the document.
So, how can i do this? Is there an existing class/package in vb.net that does something like this?

A while back I asked about going beyond basic FTP upload/download on this thread, and the response I got about using FtpWebRequest was very helpful. Now I'm looking at something that doesn't seem to be offered in FtpWebRequest: renaming a file on the server.
My situation: several times each month I update MyConfig.csv on my website. This file is generated on my computer by Excel to control who can access which files on the site, and it runs a bit over 1 MB. The scripts on the server parse through the file to keep things running smoothly. Given that the file can take some time to transfer, I typically will upload NewMyConfig.csv to the server with a commercial FTP program, then when it is in place I rename the existing file to MyConfigBackup20100521.csv and then rename NewMyConfig.csv to MyConfig.csv. This way, if there is a problem with the upload, everything keeps running smoothly because the existing MyConfig is undisturbed, and the window when a customer might get an error from the scripts because there is no MyConfig.csv is reduced to a couple of seconds between the two rename operations.
Now I'd like to automate all of this to happen with a VB program, but it looks like FtpWebRequest only allows you to rename directories, not individual files, on the server.

View 2 RepliesI like the PHP way of doing things but, it seems I am stuck with using a Collection of Object's to store/retrieve the data I need. I have my Collection loaded with my Objects's and the code to iterate through the collection, my problem is I am unable to retrieve the "key" as it would be called in PHP (I believe in this case it is actually the name of the object).
Consider the following example:
Dim xDoc As XPathDocument = New XPathDocument(fName)
Dim xNav As XPathNavigator = xDoc.CreateNavigator()
Dim sender As XPathNodeIterator
[CODE]...
As you can see, I am navigating an XML document, and creating an Object with some Key/Value pairs. The Object would look something like this if it were in JSON:
{"name":"John Smith","address1":"123 Anywhere St.","city":"This City","state":"FL"}
When I iterate though the Collection I can only get the value of the object, but I need the Key, in this instance I want "name","address1","city","state" to be stored in a variable for each iteration.
