I want to decorate a VB.NET class with meta data to describe additional information associated with the properties of the class. Also I need this information to be visible through reflelction.Is this even possible for me to accomplish?

View 1 RepliesIve come up with an issue in a program im making, hoping someone might have a clue. Basically I want to enable meta gaming into a ORPG I play. Obtaining all the meta gaming was easy enougth to do, now I have to add it into the game (Microsoft Freelancer) But ive run into a problem.I don't have a clue how. Basically, Microsoft Freelancer has a "chatbox" and I want to pass skype to and from the chatbox using VB.So if I want to type "Hi everyone" into skype, I would type "/s Hi everyone" and theoretically my VB app catches the message and passes it to skype.I can do that part using windows hooks. But when skype chats back, How to post into the game?Ive run a sniffer, But I get data that I have no Idea what it is.0000 80 06 01 00 CD DE 00 00 93 F5 06 00 I do know the ip im sending to and the port, If that helps, And the rest of the program functions, just sending and receiving the chat data is beyond me atm.
View 1 RepliesI've been using the process shown here: [url]
For including images in my database, what i would like to do during the import process is capture some of the meta data to store against fields in my database as well.
In this case we will be using iPhone 4s which i believe capture data in EXIF format.

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 trying to analyze web pages for seo. I'm trying to create my own personal tool to extract all the keywords and tags from web pages (a little clearer).I already know how to extract or parse links and text from web pages. The issue is that I tried to implement title tags, body tags or keyword tags in general via using the following code:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a")
For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("href").Contains("http://twitter.com/") Then

Try to extract all the keywords from the title, body etc. for this page:[URL] and send it to separate textboxes (title keywords in textbox1, meta tags in textbox2 etc.).

View 1 Repliesi have a windows form created using vb.net 2005 that allows users to attach files. When the user clicks the AttachFile button, they browse to select a file they want to attach and then the code places the file they selected into a predetermined location. The primary file type they will be attaching is a windows meta file (.wmf).
The attached file is saved and appears as a hyperlink for the user to open at a later time. When the user clicks to open the file, it is suppose to insert it into Autocad; however, it wasn't doing this.
The problem comes from attaching the file using the StreamWriter for some reason its not working correctly. I verified that this is the issue: When i hardcoded the file path to the original file's location, it opens up just fine when clicking the hyperlink. When I compare file size from the original to the one attached, I see that the original is 12Kb and the one I attached is 19Kb.
Here's my code to attach the file: I'm thinking perhaps it has something to do with this line? sReadFile = sr.ReadToEnd() but I'm just not sure. I tried changing this line to sr.Read but that doesn't work either.

How do I Edit and Save Image EXIF / Metadata / FileInfo without using an external DLL?
Project:I'm building an app for personal use to rename, retag, and organize the apocalyptic quantity of images I host on my personal website. As I have been collecting funny pictures and such for several years, there is no real rhyme or reason to the file naming conventions. Ergo, Image0001.jpg needs to be renamed to a descriptive filename, and the Metadata fields need to be filled in.
The desired process will take an existing jpg, gif, png, tiff or bmp and do the following:
load image into memory
convert bmp files to jpgs if needed (for a smaller file size, mostly)
load image tags into ImageData Structure (see below)

(Later, I will also be using SQL to build a referential database with links to the online copies of these files to allow for searching by keywords, subject, filename, etc, but that's another layer that's much easier than this one. At least to me.)

I have a standard "class library" project with a set of classes that I use to import in almost all my new projects.
The way I work is creating a new Solution with an empty project, which is my main project, and then I add to the solution the mentioned class library project, this way I can see both projects in the Soluction Explorer and even see the library code or update it if needed. Then I write the code in my main project and I compile.
This lead me to have 2 files when I compile: file *.exe and stdlib.dll
Some cases I use the lib for very small tools that I want to redistribute in a easy and clean why, so I would like to embed the stdlib.dll generated from my class library project into my *.exe file.
I'm designing a small GUI Windows program that allow staff at a cinema to reserve seats for customers. There will be a total of 60 seats in the cinema. I have two classes in my program:-
1.) MainForm.vb - used for I/O actions and user interaction
2.) SeatManager.vb - used to hold and handle the background methods and functions that make the program work
Here is the code for my MainForm.vb class thusfar:-
Public Class MainForm
Private Const m_totalNumberOfSeats As Integer = 60
Private m_seatManager As SeatManager
[Code]....
Basically, when the program opens, the lstReservations list in the MainForm class will be populated with a total of 60 (m_totalNumberOfSeats) entries to represent 60 seats. Each of these seats will contain the index number from the array m_nameList; this index number (+1) will represent the seat number and then in the lstReservations list, after the seat number, I'd like it to contain the respective entry from the m_nameList array. As all entries will be held in RAM, when the GUI is opened, all m_nameList array entries will be empty. As the user uses the program, they can highlight a row in the lstReservations list and then use the GUI textboxes to enter the customer's name which will then be populated into the respective array entry.
how to, when the GUI opens, ensure that the lstReservations list takes all of the blank entries from the m_nameList array and from there, I can highlight a row to carry out further methods on?

View 1 RepliesI am looking for information on the best practices or project layout for software that uses SQL embedded inside VB.NET . The software will connect to a Access DB. The software was written in VB.Net .Update: To clarify. We are currently using OleDbConnection,OleDbDataAdapter, OleDbDataReader to connect to the database. What I mean by embed is that the SQL stored procedures are scripted inside our VB code and then run on the db. All of our tables, stored procs, views, etc are all manipulated in the VB code. The layout of our code is quite messy. I am looking for a better architecture or pattern that we can use to organize our code.
