View 7 RepliesMy request is a difficult one. What I wish to do is unlock a machine when my program recieves a command. I have searced a lot and found nothing which helps. The reason I wish to do this is simple. I have created an application which allows me to send SMS messages to my computer via twitter. One of the commands is to lock the work station. This was implemented without any problem. However, I do not know how to unlock it when the application recieves the unlock command.

I have a voice program that can compare voices to stored voice files and identify people based on that. It's not the most accurate thing, since being sick or other weird things can make it fail, but it does work for the most part. I was wondering if there was a way to keep the voice recognition running during an unlock and wait for the person who locked it to come back. Upon giving the command and voice verification, if it passes, the computer is unlocked by my program. Is there anyway to do this in VB.NET?Summary: Can a program unlock a computer after it's locked?

' Validate If Not postedFile Is Nothing AndAlso postedFile.ContentLength > 0 Then Dim desc As String If tbDescription.Text = "" Then desc = "" Else desc = tbDescription.Text End If

I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

When you push it an "Open" dialog box opens (like OpenFileDialoge). What I want the program to do is auto fill in the direct file location for the website. So that the dialog box won't open or won't need input.

i created a form with a combobox that lists out Assignments ( assignment 1, assignment 2, etc...)......what i need to do is let the user choose an assignment, then the program should look for the matching text file in a folder, ex: user picks assignment 1, and the program will read from assignment1.txt and display the result in a listbox. I have everything except the coding to match what the user chooses and the text file to streamread.
View 10 RepliesI'm writing an Excel file recovery program with VB.Net that tries to be a convenient place to gather and access Microsoft's recommended methods. If your interested in my probably kludgy, error filled, and lacking enough cleanup code it's here: http:[url]..... The basic functionality seems to work although I haven't tested graph macro table recovery yet.
It occurred to me that Vista and Windows 7 users could benefit from being offered a list of previous versions of the file within my application if the Shadow Copy Service is on and there are previous copies. How do I do this?I looked at a lot of web pages but found no easy to crib code. One possibility I guess would be to use vssadmin via the shell but that is pretty cumbersome. I just want to display a dialogue box like the Previous Versions property sheet and allow users to pick one of the previous versions. I guess I could just display the previous version property sheet via the shell by programmatically invoking the context menu and the "Restore previous versions choice", however I also want to be able to offer the list for Vista Home Basic and Premium Users who don't have access to that tab even though apparently the previous versions still exist. Additionally if it possible I would like to offer XP users the same functionality although I'm pretty sure with XP only the System files are in the shadow copies.
I looked at MSDN on the Shadow Copy Service and went through all the pages, I also looked at AlphaVSS and AlphaFS and all the comments. I'm kind of guessing that I need to use AlphaVss and AlphFS and do the following?Find out the list of snapshots/restore points that exist on the computer.Mount those snapshots.Navigate in the mounted volumes to the Excel file the user wants to recover and make a list of those paths.With the list of paths handy, compare with some kind of diff program, the shadow copies of the files with the original.Pull out the youngest or oldest version (I don't think it matters) of those shadow copies that differ from the recovery target.List those versions of the files that are found to be different.This seems cumbersome and slow, but maybe is the fastest way to do things. I just need some confirmation that is the way to go now.
Possible Duplicate: Which language should I pick up: VB.Net or C# I'm trying to make a descision on learning VB.NET or C# as my first .NET language. I'm aware that bith languages can achieve the same things since both ultimately use the .NET framework. I'm also aware that C# has a similar syntax to both Java and C/C++, so I definitely see the benefits with this.
But how about the future of VB.NET? Will it be maintained in the years to come?I do know a bit of python, so would that make C# easier to learn?
