• Visual Studio Express Editions VB File.Encrypt method

  I am trying to encrypt a text file in VB 2005 Express and found a couple of pieces of code that demonstrate it. I have used the following Imports: Imports System Imports System.IO Imports System.Security.AccessControl I am calling the method with: File.Encrypt(FileName) where Filename has been DIMmed with "D:\EncTest.txt" I get an IO exception stating that what I am trying to do is not supported. Going through the help system, I was told that this means that my file system is not NTFS. Looking at the properties of my D: drive, it says it is NTFS. The text file is definitely there, named correctly and not in use by any other application. Is this something wrong with the way in which the path is express ...Show All

• Visual Basic Newbie needs guidance on the next step past GUI--Importing Stock Data into App

  I'm taking a VB class for financial analysts, and we're tasked with constructing a progrm we can use on the job. What I'm trying to do is build a VB program that will take Stock and Company information from certain sites on the Internet and extracting that information into the program to do some research on a company before investing. I have some grand plans, but based upon what I have read/heard I'm starting by taking stock information from two websites (Yahoo Finance and Reuters) and populate several different tabs in this program I'm making (exporting to an Access database and Excel are also in the works, but I'm taking baby steps). I built the GUI with 4 different tabs that will house Earnings data, Trading Information, Company News, ...Show All

• SQL Server Virtual Labs - Resources available?

  Hi Forum You can download a lab manual for the virtual labs. But what about the resources Does anyone know The remote desktop connection is too slow so I can't take the actual virtual labs. ..or it would take like 4 hours to run a 1 hour virtual lab.

I'm looking for the one on Service Broker We don't cover the virtual labs in Books Online, but you can learn more and get them here: http://msdn.microsoft.com/virtualla ...Show All

• Windows Live Developer Forums Navigate freely through IFrame element in activity?

  I have read some articles about the activity,Activities we made must be posted to gallery to review. If I used IFrame in my activity,and the content or the URL in IFrame are stored in database and will be read while activity is running. I want to ask this is legal or illegal. If this is legal,then I am confused why our activities must be posted to you,because we can place anything in our database as we like,MS only checks the skelton but not flesh. If this is illegal ,how do I do to navigate many pages in activity's little window. I would assume that this would be ok. The reviewers can't possibly test all permutations of input into the activity window, so I assume that they will test as mu ...Show All

• Software Development for Windows Vista Problem with BindToObject

  Good evening. I had made a little console application that ran a filtergraph for a webcam. It worked fine until we tried to get it working with a GUI and this whole "managed" code thing. I have a class that enumerates all of the video capture devices and tries to return the first one. BindToObject does not return 'gottafilter'. It's just empty. I can see my webcam in the devices array. After much searching on the Internet I am still clueless as to why this does not work. Any help or alternative methods will be appreciated. Below is my code: Note: Have included DXSDK, WindowsSDK (just in case) libraries and includes. HRESULT GetVideoInputFilter(IBaseFilter^% gottaFilter ) { array <DsDevice^> ^devices = Ds ...Show All

• Visual Studio Express Editions spellchecker?
