View 1 RepliesTo simplify things, I have a new VB .NET 2008 Windows Form Application with absolutely no code yet. The only control I have on the form is a stock standard imagelist common control. Using the inbuilt editor for adding images, i've added one single 16x16 jpg image (just to simplify things). If I build and run the application at this point I get the following error.An error occurred creating the form. See Exception.InnerException for details. The error is: Index was outside the bounds of the array. I don't expect to see any images at this point when I 'Run' the application. I just need to work out why I'm getting the error. Later on I'll be referencing the imagelist in another control.
View 1 RepliesI seem to be having a problem with controls that I am creating as new classes (not UserControls) inheriting from an existing system control. Everything seems ok while I create the control code, through to the compile (which is successful and adds the control to the toolbox) and dragging the control from the toolbox to the GUI surface. However, when I then debug or compile the project, I get a message such

View 2 RepliesI have just finished college and I am awaiting my exam date. I have created some desktop applications for my portfolio, but now I want to create a Point of Sales (POS) system to add to the list.I notice in supermarkets and various shops that POS systems use touch screen monitors to interact with the program.My first question is, do I need to use different code or controls in my applications so they can be used with touch screen monitors.I have created an application for hotels for booking rooms (not for a client, just as a demo project), but if there is anyone out there who could give me some pointers on how to create the POS system.I will be doing some research and I will start designing some controls over the next few days. I am looking forward to getting this project started.
View 2 Repliesi want to create a simple POS system, can you tell me how can i hide group of buttons/ controls on the first load of a form and then group of controls will just show after a button is clicked or selected. Also i want to have a display (on same form) of what is selected by the user.
View 3 RepliesI have a program that I have gotten as far as programming it to inform the user of updates, have them push a button to download it. The updated version of the exe will be downloaded into a subfolder called "Updates", where there is a program called "Updater.exe"This program is one form, with a progress bar and informs the user the program is being updated. Every time I run through it step by step it appears to work, but in a real environment the program stalls out. It doesn't crash, but the bar continues to move with no action being taken. I can not help but wonder what on earth must be going on in the code, which you can see is quite sloppy and rather unweildy:[code]And there is of course the issue of not being able to change data on the hard drive without administrator privileges as is being discussed here: url... When I finally get a manifest working for this program to require administrator access....how could that screw up this updating process...How can I better perform this, what seems to me, simple process of deleting the old file and replacing it with the update?

I am trying to create a new folder in C:\Windows\System32\oobe but I cannot get sufficient privileges. Here is the bit of code that has the error
' I have "CreateDirectory("C:\Windows\System32\oobe\info\backgrounds") in the Form load sub
Sub CreateDirectory(ByVal Path As String)
Directory.CreateDirectory(Path)
End Sub
And then in Form Load I have:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
CreateDirectory("C:\Windows\System32\oobe\info\backgrounds")
End Sub
It keeps saying I don't have the privileges. Is there any way around this? I also need to put files in that folder later on.

I posted this through my phone originally, and I am now just getting back to this post.
I've been looking around the web and while reading Wikipedia's article on SHA, I see that SHA-2 (SHA-256/224, SHA-512/384) have no detected collisions (assuming the article is accurate/up-to-date). This is desirable. Any recommendations on what version of SHA-2 I should use?
I thought that creating a simple system service under VB .NET would be a piece of cake. Boy, was I wrong. First, I find general postings through Google that say you should use the Windows.Forms.Timer. Then, I found conflicting information that says you have to derive the timer from a timer class through code to make it work. Then, people are reporting all sorts of trouble using the various types of threads available. I can't debug threads using the VS 2010 Just-in-Time debugger for obvious reasons (although, I don't know if there is an alternate method to doing this).My project is an application launcher (similar to cron) that will fire off periodically within a certain amount of seconds. I am trying to use the Process.Start() method. I have a Beep() function as the first instruction, and the Process.Start, along with a Process.WaitForExit method to make it block as the last instruction. I had my code doing this through timers, but now I am starting to use threads. No difference in execution. The over-ridden OnStart method does kick off (as I am certain through debugging), but nothing ever happens when starting the service in production, as if it were ignoring all my code. Putting loops and logic in the OnStart method yields a process that won't start. I know it is a threading issue, but I also know it must be mandatory to use threads. I am now dumbfounded as to how to make this work. I am curious to know the solution.
In addition to the service class, I have a ServiceInstaller and ProcessInstaller implemented that I copied verbatim from MSDN.Here is some of the code I am trying to work with. Note that this simply reflects the current state of my code in trying to implement the logic within a thread instead of a timer (which to me would be optimal):[code]
I'm having problems with a stock program that I'm developing. It's a program that adds a quantity of products to a field called stock quantity in a table named Stocks. In the part of adding a quantity inserted by the user it's ok, it works, but it adds to all fields in the table.I need that the user may choose also the product Id of the product to add, in order to prevent the situation above.

View 1 RepliesI am currently creating an application to track timekeeping (a clock in/out system) and I am trying to work out the best way to do this.
I have a Main Form which contains buttons to ;
- Log in
- Out for Break
- In from Break
- Log out
When a user presses the "log in" button the logon form appears, the user then enters their username and password. What happens next is where I would like the help.
Process is as follows:Click Logon Enter Username/Password Check Logon Form for errors (eg no password etc) Check User is in Database (using SQL query) If user is in DB and username and pass are ok then refer back to the main form to perform Stored Procedure for what the user wants to do (eg logon or or out for break etc). Set label on main form to show user as logged on My question is should I be using a public variable and calling the main form again or in the user logon form having 4 options and using an IF ELSE to select the appropriate Stored Procedure?
Im in the process of creating a task loggin system for my work, and im in the final stage now of tidying the design etc, and i have a text area where a scroll bar is visible but disabled, is there a way to remove the scroll bars completly and when the user goes passed a certain line make them appear? i no i could say scroll bar = false but i wont it to appear when it hits a certain line.
