Vending Machine Repeating Error
Jul 14, 2009
I am currently creating a vending machine program, designed to simulate a vending machine. However I have come across a rather large error, my stock is 50 at the begging. The person can go though the program and the appropiate amount of stock is taken away from the relavent object, however when I finish and want to go back to the start the last selection is still present.Therefore I have tried setting the variable as 0 when the form opens and when the program starts, but the last selection is still present.Does anyone know of a way to which I can reset this calculation without affecting my stock so I can then repeat my program cycle one or two times each time using the previous stock without reseting back to 50

I just started doing a semester of Visual Basic in college(australian), our first assignment is to make a vending machine app but so far we've only been taught basic coding such as making time converters and forms. I've tried to ask the teacher for help and she refuses to help us, she tells us its unfair. None of my friends in my class know where to start and everyone else is cheating of the internet. I just want to know how to start making the application. The vending machine must have 6 products with 10 of each, the user must put in 10c, 20c, 50c, 1 dollar and 2 dollars. Everytime the user buys something it must deduct 1. The must also be an admin function.

25, .10 and .5... I cant get it to add. All it will do when each button is hit for each ammount is display that amount. Very frustrating. Here is an example of my machine:

I am making a Vending machine that requires you to logon and then you can purchase things and the purchases are deducted from your balance. The logon information as well as the balance is stored in an access file. I have the logon working well and understand everything except the things dealing with the balance. How can I make it so that when you logon it takes you to the purchase screen and The person you logged on as name and balance are shown on labels. I also don't know how to deal with balance. So when they log on and purchase the amount is detracted from their particular balance.

I have a program that continuously reads in hex values as part of an rfid reader. My question is: How would I write code that detects when this changes? i.e. I have a visual basic textbox that is continuously updated as so:

And it points to the name of my form. This occurs at the "newArray(p) = strangeCardNames" line of code. If anyone else has an idea for how I can either fix this or another method to detect a change and store it in a variable,

I have created an application using VB.NET in VS2008. When I run the app in the IDE on my development machine it works fine. It also works fine when I build it and run it as an exe on any machine that also has Visual Studio installed (at least 2005 and 2008 anyway) However, when I try to run the compiled executable on any machine without Visual Studio it throws up an error "[program name] has encountered a problem and will close..."

I have been tasked with getting a asp.net (vb.net) talking to an analysis services engine on our production servers. The web server is a separate machine from the web server.The web server runs as the IUSR_ user.The application (of course) works on the development machine which has both IIS and Analysis services on it.The problem I see appears to be a permissions error (returned in the browser by the asp.net app):An existing connection was forcibly closed by the remote host ....
it is described in a similar post here: http:[url]......I am not a system admin, nor am I an expert in analysis services (why have I been tasked with this you ask? because other people haven't been able to get it working and it has fallen on me). I have tried creating and adding the user (IUSR_) to the sql server and added that user to the role. While that worked on my local machine, it did not work in our production environment where the sql and web servers are separate.

I have developed a 32-bit VB.NET application that runs fine on 32-bit systems. Some of the folks in engineering, however, are using 64-bit machines, so we have created 32-bit virtual PCs and installed the application on the Virtual PC. When we try to run it, however, the application fails to establish a connection to the SQL server (remote, SQL 2000) for login validation.

We have an application (Vb6) that gets installed at all of our client sites and they often (Vista/Windows 7) run into a the error message Unexpected error, quiting after a install on a new machine. The problem comes about when the UAC is on and the application is trying to create registry entries in areas it doesnt have access to because the application is running as a standard user. If the user runs the application as an admin the first time, everything sets up and life if good.
My question is, what is the most elegant way to setup those registry keys without forcing the user to run as an admin the first time? We could force them to run the applicaiton as an admin using a manifest file, but I dont want them to have to run as an
admin every time, just the first time.

I have an old app, a VB5 front end with access 97 databases all works Ok using the ...program files... folders in XP but I now have a user on Vista and we have problems opening up, and I am braced for problems saving and closing down, if we ever get there.
I sent him a c# applet which found the users folder using string Dpath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
I have moved the data and all settings files to a folder C:Users[Username]AppDataLocal[My app Name][My app data Path]
The start up routine checks a settings file uses the path in the settings to re-attach the front end database to a backend database, test to see if the database uses replication and set the default data path for the rest of the app. we are failing somewhere in here I am sure. I have checked and there are no updateable files in program files
Have I got the wrong path or is there something else I should be looking for?
I have an vs2008 version of the app which is using a similar location but a SQL server database- no problems

I have an xml file I parse to get a path to some other xml files that I then want to parse and read values from. I am fine to get the path from the first xml document and fine to parse the subsequent documents.Where I am struggling is implementing the path. It is being stored using system level variables like:
%appdata%my_appconfig
When I try open the file like this:
xmlConfig.Load(userConfigFile)
It tries to start in the application working directory - assume c:emp So the error message I get is:
Could not find a part of the path 'C:emp\%appdata%my_appconfighive.machine.xml'.
Is there a way I can use this pathing structure in my VB code or determine the actual fully qualified path programatically?

My first project was a small windows form application that I'm hoping to put on the office server and have it accessible to more than one person at a time. I wrote the code in Visual Studio, and put the exe file and access database on the office server. When another computer (that doesn't have visual studio installed) opens the file this error comes up: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. I realize I may need a quick download on these other computers to be able to read the VB program?

I've inherited a lot of custom made software for an office, and, while managing it, I've found it performs differently from machine to machine.I mean, some controls get painted in weird ways in some machines but well in another, or just work differently, like in some machines clicking something selects it, and in the next machine clicking the same thing makes it editable.I suspect, o course, of the myriad of DLL the software loads
