Locate An User's Desktop?

Feb 2, 2010

I am making a program that stores all information that is entered into a directory and then zips that directory onto the C drive. It is working perfectly fine, but I think it would be easier for the user if the final directory was zipped onto the desktop.

Is there a way that VB.Net can locate the user's desktop and then zip the directory and place it on the desktop? For example, zipping it to "C:Documents and SettingsAdministratorDesktop" would work on my PC, but it may be different on a user's computer.

Allow The User To Vote For Any Contestant Any Time By Entering The Last Name Of The Contestant"?

May 5, 2011

I am having much difficulty with it... heres what i have to do

"Write a program that allows users to vote on their favorite singer American Idol style. Your program should have the following features:

Your program should use a single listbox to display the names of the contestants and the number of votes for each contestant.

Use a class to hold the contestant�s first name, last name, and number of votes. The class should include a method to increment the contestant�s vote count by 1. Be sure to use property procedures for the first name, last name and number of votes properties.

Your program should read the names of contestants from an input file and display them in the listbox. You cannot make assumptions about how many contestants there will be in advance.

Your program should allow the user to sort the contestants by the number of votes they got. It should also allow the user to vote for any contestant any time by entering the last name of the contestant."So far this is the only code that I have... not sure why nothing is working.

Public Class Form1
Dim count As Integer = 0
Dim namearray(0) As Contestant[code]....

Any Way To Locate Desktop Path For User On Another PC?

Jun 1, 2012

VB2010. I'm trying to figure out how to locate the desktop path for a user on another pc/server. Something similar to:
Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
The main reason is we area talking about an Environment that has XP, Win Server 2003 (TS), Win Server 2008 and Win 7. Obviously different path depending on the OS. I need to copy a file to a users desktop and would like to do so without having to hardcode the path as it could change depending on where they are working from.

Create A File On The User's Desktop

Mar 4, 2011

As part of a program for class we were instructed to create a text file on the user's computer. The instructions were to create the file to the C: (or the same drive as the Windows directory) but Windows7 requires Admin privileges to write to this directory. It works great if I run Visual Studio as admin, but I'd rather just write to an unrestricted area. For example the desktop. Is there a way to write directly to the user's desktop without knowing the user's username. Right now I'm using this "c:UsersNickDesktopScores.txt"; which works but of course the user's name is different on every machine. How would I go about specifying the user's desktop?

Discover The User's Desktop Folder?

Jun 24, 2011

I'm making a little application in visual studio which loads a ROM in an emulator. I have two emulators and 20 ROMs.I made a form and added a few buttons. When you click the Button it opens a new form and closes the old one. Then on the new form I have four buttons: each one loads a different ROM in an emulator. So when you press Button1 this code is triggered:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles yellow.Click
Shell("C:UsersshiftyDesktoppokemon gamesEmulatorVBAVisualBoyAdvance.exe ""C:UsersshiftyDesktoppokemon gamesRomsYellowPokemon Yellow.gb""", vbNormalFocus)
End Sub

It works fine - I click it and it loads the game in the emulator. The bit im having trouble with is the file paths. If I send this application to a friend, it would still look for "C:UsersshiftyDesktop" - but that's on my computer, not his.Is there a way to make the application look for the file on his computer (without changing the file path to (C:Users""his user name""Desktop))

How To Disable The User's Mouse

Oct 28, 2010

What I have so far is a program that moves the mouse around my application. I used a bit a maths as well to make the movement smooth. Here's my code for anyone who is interested:

Code:
Public Sub MoveMouseCursor(ByVal DestinationX, ByVal DestinationY)
Dim DifferenceX As Integer = MousePosition.X - DestinationX
Dim DifferenceY As Integer = MousePosition.Y - DestinationY

[Code].....

Now with my problem. When the program is running, the last thing I want is for the user to be moving the mouse because the program would get disrupted. How can I enable and disable the use of the mouse for the users benefits really because if they even knock the mouse slightly it could cause them a few difficulties. Anyway, I am hardly restricting them from using their computer because there is only one mouse. If they want my program to run, then they will have to except the fact that they can't do something else in the mean time. Also, after the program has finished running, I will need to enable the mouse again.

Method To Develop And Deploy A Multi-user Desktop Application?

Sep 17, 2009

I have developed an application using vb.net. This application will run on approximately 15 machines at the main office and also roughly 10 machines spread over 3 different locations. I am using SQL Server Express edition in the backend. I deployed the application on the network using caspol but it is extremely slow. The Company Manager's perception is that because a script will invariably have to be deployed on each client machine to configure CASPOL, that the solution is not viable.

What is the best method to develop and deploy a multi-user desktop application?

User Can Disable The Splash Screen If He Wants?

Jan 6, 2012

I want that my application will have a splash screen - thats easy. The problem is that I want to give the user the ability to disable the splash screen if he wants. If I set this in the application splash screen settings then there is a splash screen,but there is no way the user can disable it. If I do it without a real splash screen - with a timer that closes the form and opens the real main window - the application closes itself because of the setting "Shutdown application: When startup form closes".I just can't choose the second setting (when last window closes).
