I am looking into writing a web-based vehicle tracking system. The framework I have in mind looks something like this:
Client application --- Database --- Database updater.
Client application: This would query the database for information and then display this information on a map.
Database: holds vehicle information such as speed, location, payload etc.
Database update: This application would need to continually check for information received from vehicles and then add that to the database.
I am confident that with my current skill set and some research and learning, I could write the client application and interface it to a database. However, I am at a loss as to how to write the database updater. Presumably, this would be an application running continually on the server, waiting for information to be received from vehicles and updating the database. Is this something I can do with ASP.NET and Visual Basic? Or would this require a different way of thinking than writing web pages?

View 6 RepliesI am using Visual Studio 2008 on Windows XP SP3. User has Windows 7 Pro (32 bit). The IO code below works for me. The read code works for user, but the write code only works for new files. If the user tries to overwrite a current data file, then no data is written to disk. I have done all the usual IO checking (valid file name, etc.) and have excluded it from my same code. In my app, FileSave and FileSaveAs both call WriteDataFile(FullFileName). Any reasons why FIleSave would work on Windows XP, but not on Windows 7 Pro (32 bit)?
Code:
Public Function ReadDataFile(ByVal FullFileName As String) As Integer
' reads a Data file from disk
'
' Format is a text file, with [TAB] seperators and [CR][LF] as line terminators

View 1 RepliesI have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....
View 1 RepliesI am working on a program with multiple collections related to one another for a school project. Each collection needs to have its own defined properties and have the objects written (1 per line) to a text file.
I have all of that working.
When reading the comma-separated line from the file, I want to place one of the properties of the object in a listbox (so that all the objects' names will show up in the listbox). I think I have this part figured out...
My problem is that when you click on the name in the listbox, I would like multiple text boxes to be populated with the appropriate, corresponding properties of the particular object in the collection...is there a way for this to be done?

View 2 RepliesWhat my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:
