I am making an application where a user can store their logons/passwords and other details for websites on the internet.My question is this: Am I able to have a list of all sites that the user has saved a password for on the internet?I don't think I will be able to get the password (because of Windows security), but am I able to see what sites the user has saved their password on, and maybe even the username they used?

I have a form containing a checkedlistbox, I want to be able to do a simple comparison between the checked status before and after to see if there has been any change. I have a copy of the "before" version of the checkedlist box and I thought I could just compare the two CheckedItems but it always thinks they are different, I could iterate through the entire checkedlistbox but I thought there would be an easier way.
[Code]
when your resetting a form is it possible to deselect or not keep high lighted the item that was previously selected from the last entry. I know how to clear the text boxes but the items in the list boxes stay highlighted. Is it possible to get back to the initial setting of having nothing selected as when you first start debugging?
View 5 RepliesI'm trying to create an application that is able to find products from a XML file, which will contain the following data:EAN (Barcode as a string, not an image)
Description
Price
Stock
So basically, I enter the EAN and my program will lookup the XML file for this EAN and will return the description of this product, the price and the stock in a new messagebox. However, I don't understand how to create a XML file, add items, remove items, edit items, and most of all: read items from a XML file.

I am programing a basic P.O.S. (Point of Sale) system, ad am looking for the best way to save Inventory objects. The object contains a few Singles and Strings (Such as barcode, name, price...ect). Assuming the user could possibly input thousands of such items, what is the best way to store and handle these?
My first, and simplest thought, is to add each inventory Item to an ArrayList, then once the user saves, or closes, the ArrayList prints each object to a text file, then when the program opens it reads the text file to re-populate the Array list. However, this seems very un-efficient (I assume). Would it be better to use an excell file or a Database (I know almost nothing about databases, but I can learn), or something completely different?
So I have a list of names in a .txt file. Where is a place I can type in all the names I want and press save and get a link so they can see the list. Then I can remove a name and press save and the name will be gone. And or add a name. So basically I need a website where I can type something and keep it uptodate. I've tried ripway but after you edit the list and save it it doesn't change.

Now on form load I wanted the program to automatically try and connect to the DB. No problem except the DB connection always delayed the program launching by roughly 5 seconds. So I figured a separate thread call to take the stress from the form ... and now I'm floundering ....
CODE:
simple enough on form load display the dynamic text to the status bar label named dbStatus. Than start a new thread to the address of my database connection function. This works fine, i can even throw a msgbox() inside the function and can be told its connected. But in that same function I add the line
CODE:
Commented lines were me trying to reference it a "different" way ... but every time I run this the label never gets updated, when i step through set function the 'InvokeRequired' is either nothing or false.
But of course directly trying to access the text attribute of the label doesn't work but strangely enough doesn't throw a cross thread error either.
Hence my current dilemma ... I can directly call db.ConnectDatabase and everything works as intended .. when I throw the function into a separate thread my status label never gets updated, nor am I warned about any cross thread operations.

II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:
ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$3:$AE$7"), , xlYes).Name = _
"List1"
I realize the problem is the $AE$7 (the $A$3 is correct)
In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?

Does link text mean I have to return a concrete implementation? Even though I am using svcutil with the /r that includes my entites(where IMyInterface is defined). I get no errors but it changes all List(of IMyInterface) to list(of Object) and I cannot deserialize it on the client
Error: list(of object) cannot be converted to list(of IMyInterface).
I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?
