Validate Downloaded Xml File To XSD?
Aug 6, 2010
I have an xml file that I download from a secure site every 5 minutes, I have the application set to download at 3 minutes after the hour so it runs at 3, 8, 13, and so on. The file is supposed to be there within a minute after the 5 minute increment has occured however this is not always the case, so I changed the download time from 2 minutes after the hour to 3 minutes. However I am still running into issues with it not being there even then. What I want to do is validate the downloaded xml file to ensure that the data is there and if it is not wait 10 seconds and rerun the download again.
if the file is valid it will call the SQL import Sub (),if not it needs to delete the existing file and rerun the download sub again.The problem I am having is that all the examples that I have seen when I google are for validating the xml file prior to upload or upon the xml files creation.

how I could make an application in visual basic 2008/vb2005 that detects when a new file is downloaded. One of my old time friends created the same app with visual basic 2008. It notifys you when your attempting to download a file. For e.g: I try to download "aim6.exe"
it will show a message: "C:UsersMATTST~1AppDataLocalTempsXx0Fd31.exe.part is attempting to be downloaded"
I think it uses a file system watcher.

I have made a downloader in Visual Basic 2008, using the Webclient that is built in. This is the code i have to download the file[code]...
So instead of just saving it to C: automaticlly, i want a Save dialog that the user can choose where to save the file.
I have searched for almost a hour now, but i can't find the proper code for my purposes.

I am working on a website at the moment which is displaying a strange bug with generated word documents. The site has a feature on it which allows the user to download a word document containing information related to their visit. This file is generated via some vb.net code and takes an xml template of the final document and inserts the relevant content required.
The strange behaviour is that on some machines the .doc file generated displays fine and on others it displays as XML when opened in Word. Both behaviours have been seen in the same version of Office (2003) but on seperate machines. My question is really whether the error lies with the set up of word on the individual machines, or whether there is an error in the code.
The code to create the file and download it is as follows:
Response.Clear()
Response.ClearHeaders()
Response.AddHeader("content-disposition", "inline; filename=MyNewFile")
Response.ContentType = "application/msword"
[code]....

i have a function which grabs images from urls, using this function:
Public Function webDownloadImage(ByVal Url As String, Optional ByVal saveFile As Boolean = False, Optional ByVal location As String = "C:") As Image
Dim webClient As New System.Net.WebClient
Dim bytes() As Byte = webClient.DownloadData(Url)

All the examples ive found so far point at using imagemagik or another add in.

I have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

I'm developing a VB Web Application in .NET3.5 using Visual Studio 2008. I'm having difficulty in validating some XML as a string before I add it to a HTML form to post to a 3rd party. I have an XML schema file from the 3rd party to validate against and at this point I'd like the application to perform the validation before each post.
After searching I've found references to a XmlValidatingReader but this is obsolete and I'm having difficulty finding another way to do it. Also all the good examples are in C# - for now I'm stuck with VB. This is what I have so far which I'm looking for with! Public Function ValidateXML(ByVal strXML As String) As Boolean

I am working on a VB.NET windows applications. It reads data from a text file and inserts them into SQL server DB using SQL Bulk copy.I want to validate the length of all the fields in the file. The maximum length allowed for evey field is stored in tbFieldLength table. File has 50 columns and 10,000 rows and the values are separated by '|' symbol.
If the length of a value in any row is greater than the length specified in the tbFieldLength table, I want throw an error with exact row and column details. For example,saying
"Lenght of the value in Row 6, Column 20 is greater than the expected length"Also, I want to identify all the places if the error occurs in multiple locations. What is the best way to validate the length of fields in the text file?

CODE:
But it simply won't work. It always throws that exception and I don't know why. I tried debugging and it sad that the value of bundle is nothing. The error is on this line of VB For i = 0 To bundle.MessageCount - 1
The interesting thing is that it worked ONE time only. And after that time, never again. What's the problem?

I'm writing something to download about 200 small (Around 200kb) files at a time. I pass the file urls off to a class which starts the downloads. The problem is that it'll start the download (Just creates a 0kb file) and then slowly downloads each file one by one, waiting for the next to complete despite this being a threaded class. This would be fine but after about a minute, windows removes all of the 0kb files and I'm stuck with only a few of the files being downloaded. How to get multiple files to be downloaded concurrently?

I'm just starting out with VB and have downloaded and installed VB Express 2008. I'm researching and trying to wrap my head around programming in VB before I start working on any projects. I have a little bit of experience with ASP Classic so some of the syntax looks familiar, but I can't get a handle on database integration. Let's say I am creating an address book. Each installation is a stand-alone (no network connectivity). How are databases used in this situation? Are they built using VB Express and packaged into the installer or can you create them separately (using either Access or MySQL) and then package them into the installer? What is needed to read and write to these databases? Are there extra bits of software that need to be packaged into the installer to allow access to the databases?
What if this application does connect to a centralized database (let's say a MySQL or Access database on a web server). Is the connectivity handled the same way? Sorry for so many questions, but I just can find the answers I'm looking for when searching. I'm not necessarily looking for the actual code to do this, just an explanation of how it's possible (or even a link to some examples/tutorials).

I am trying to use Vb to call explorer to open some web pages that I already downloaded. I use this command.
Shell("C:Program FilesMozilla Firefoxfirefox.exe G:BlogsBlog35242+0")
it works fine for this file. However, I have tens of thousands files to open. So I need a variable to replace "G:BlogsBlog35242+0". Like, I write blogaddress="G:BlogsBlog35242+0" and Shell("C:Program FilesMozilla Firefoxfirefox.exe blogaddress")it doesn't work.I write, Shell("C:Program FilesMozilla Firefoxfirefox.exe" &blogaddress) it doesn't work either.
