I need to create something that will retrieve new Users from a VTiger CRM and create a FTP folder and user/pass on another server.
SERV-A: VTiger CRM, powered by MYSQL. With WSDL directory.
SERV-B: FTP server
The reason why I thought doing a WebService is that I must constantly check for new users. The language used isn't an issue. How to automatically retrieve changes of a MySQL DB from a webservice // Better solution?

I created a script for caching some images my program needs, so they aren't downloaded from the web everytime. But the cache folder is getting big, and it's getting big fast. It's not really the plan to have a cache of 1Gb or something like that, so I would like to create something like this to set the maximum size:
But I don't really know were to start. Sure I can create some check, and if the maximum is exceeded, remove the whole map, or the oldest files. But maybe the oldest files are the one's used the most.

Using VB 2010 Express, I will try to explain what I want to achieve:1. The user installs my program.2. In an Explorer window (Vista/Win7) the user will right click any file.3. The program checks if there is an item called "MyApp" in the context menu (i.e. the menu with for instance the "Open with..." item). If not, then create the "MyApp" item which launches "TheRealApp.exe" that the user installed. Place the item after the "Print" item.

I have discovered Environment.SpecialFolder.MyDocuments and My.Computer.Filesystem.SpecialFolder.MyDocuments
I know how to check if the folder exists, but it's awfully difficult to find a way to create a folder in a 'special folder'.
How do I programmatically create a folder in the users 'My Documents'?

I am working on a project where I create image files from calculations done from user inputs. The work is saved as jpg images in various sized and I want to add EXIF data to the saved filed and later on retreive these data again so the user can continue working on the basis of a re-opened image file as I hope to store the project variables as metadata in the image file.

I am trying to create a LINQ query statement that retrieve intersecting data from 3 datatables (dt, dt1, dt2). My first attempt to do so with the following LINQ query statement was successful: [code] However in my design, I would need the LINQ query statement to be dynamically generated, because I want a user to be able to retrieve intersecting data entries from VARIABLE number of datatables. In this case, the first option is not as good as the "INTERSECT" query operator, with which I can just easily connect each SQL query statement with a "INTERSECT" operator. The problem is that my second attempt using the "intersect" operator fails, and after many trials and errors I still can't get it to work. [code]

I have the following VB.NET code to set and read objects in cache on a per user basis (i.e. a bit like session)
Public Shared Sub CacheSet(ByVal Key As String, ByVal Value As Object)
Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(Key & "_" & userID) = Value
End Sub
[Code]....
I use these functions to hold user data that I don't want to access the DB for all the time. However, when the data is updated, I want the cached item to be removed so it get created again.
How do I make an Item I set disappear or set it to NOTHING or NULL?

We are developing this system that's constantly connecting and retrieving records in our Sql Server 2000 database. The problem is. is that when the database is down we can't use the system. So we are tasked to modify the system to have offline access feature without data replication rather making a xml cache or any flat file data cache.
My question is, what is the most optimized way to make this work?
BTW, the offline data should be synchronized when the server gets online.

We have data that's updated nightly in a database residing in the same instance as my app's database. So to save on database calls, I want to cache this static-for-the-day data into a List(Of MyObject). From a theory point of view, should this cached List(Of ) be cached in the presentation layer code, via a global variable? Should it be in a global variable in the .DLL?I'm thinking in the .DLL, because I created a service layer, which is exposed publicly to the GUI and makes calls to the data access layer inside the .DLL:
Public Shared Function Search(ByVal criteria As Core.Other.Customer) As List(Of Core.Other.Customer)
' TODO: Check the customer cache to see if it has been populated yet. If not, populate it.
If 1 = 1 Then

i have a list box which is populated with the sub folders from a user selected folder, so the listbox item count varies from 2 item to 1000 items etc.The list box code i use to do this is:
Dim lb1s As String = Form1.Folder.SelectedPath
Dim di As New IO.DirectoryInfo(lb1s)
Dim mydirInfoArray As IO.DirectoryInfo() = di.GetDirectories
Im trying to make a feature were on a button click the app will create 1 folder for every item on the listbox (named after the list box item)So if theres 3 items on the list box for example:
001
002
band 3
[code]....
And when the user presses the button, the app will create 3 dupe folders (Only the folders, not the contents) in a user selected directory using the same names, ive been tinkering for a little while but cant seem to figure out a way to implement this.
