I would like to know if the .NET framework gives you a way to retrive the littles thumbnails Windows XP+ generates when you alt+tab. The application I try to make should be able to get a window capture (ALT+PrtScr) of another Window that is not necessary Active and could be partially or completly hidden behind another one. I tried the codes found there [URL] altprintscreen with no success in the case the window I'm trying to capture is not visible.

View 1 RepliesI have a custom bar code app running on .Net 2.0 framework and installed on a Windows Terminal Server. I'm using HP type thin clients and they are pulling their desktop from the TS that has my barcode app installed on it.For the most part, the barcode app runs with no problem. The only issue I have, is that my barcode app needs to print labels to a specific printer based on the work center that the thin client is located in. The barcode app was designed to route the labels based on the device name (Windows name) of the system that the barcode transaction originated from.I have full blown Windows XP Pro systems also running the barcode app and I have no problem with the label routing because each of those type systems has a unique name that I can use for routing. Where I'm running into a problem is that the barcode app running from the thin clients, appears (from the barcode app's point of view) to running from the Terminal Server not the individual thin clients.
Does anyone have any idea how I can pull some type of unique identifier from these thin clients to use within the barcode app to use for routing of the labels?
Anyone know of a unique identifier I can grab from a Windows PC?I am working on licensing of my app and I want to assign the user a license key and have the key and some unique piece of data from the PC hit a database server of mine and then check credentials before the program runs.I thought about using host name but that can be cloned. I also thought of MAC address but if a computer has a wired and wireless NIC then there are multiple MAC addresses.

When the session is about to timeout, the client should be presented with a POP-UP that asks to click OK to extend the session or else cancel to timeout the session.

I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

View 1 RepliesI am having a namespace extension implemented, which is visible in "MY Computer". I want to write automated test cases to browse through the same. I am able to open the explorer window till the namespace extension. as -
Process.Start("explorer.exe", "shell:::{CLSID of my namespace }")
next I want to search for a particular folder name inside the window opened. For example if i give input as "temp", then my mouse should move to "temp" folder in the namespace explorer window. then I double click on the mouse's current position and enter that folder. next i give input as "doc1.doc", then my mouse should be able to locate & move to "doc1.doc" file. Also getDirectory or GetFile etc APIs won't work because I don't have a standard drive associated with my namespace & don't have a relative path either.

I would like some information on pausing my application until a file with a certain extension has been created. What hapens is, my application creates an input file that is sent to an external app that returns a file with a different file extension. In my application i then extract data from this new file.I was thinking i could use a timer to "hold up" my app, but then i started reading about event handlers and catchers. What i have tried is using an If FileExists loop but i get a file not found exception. How should i use the file create event? By looking in the folder and "waiting" for the file to be created?

View 2 RepliesWhy would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?
