I'm currently designing a mock-up of a customer booking system for a cinema using Framework 4.0. All data at present will be stored in an array and as it's a mock-up, it will remain their (customer name, ticket price etc...) as no requirement to permanently store the data at this time.[code]...
View 1 RepliesI'm trying to put together a quick program for our database, I haven't touched VB since vb6, and we have 2008 .NET now. my question.
Ideally I'd like to make an array which can hold multiple values...such as
Job[job#].joblocation
Job[job#].jobsupervisor
So there would be a Job array, and then different values contained within that. I can't seem to make an object or whatever which allows me to hold different variables inside it.
I want to create an array of constant variables for my program. But from everything I read about arrays they are handled by a number. I want to be able to pass back a variable that will hold the name of the constant as well as the value. How would you go about do that.I want to when I type the variable to have the constant name show up as I am typing.
View 4 RepliesI'm trying to write a program to call Quickbase and retrieve a database and put it into an array. It's a contacts table that I need to be able to query and select different fields according to letterheads, memos, etc. I've tried to do this three different ways.
1.) Find a direct port or some way of accessing Quickbase directly, similar to connecting to an oracle database or MS Access.
2.) Export the table to MS Excel and read the data from a spreadsheet.
3.) Opening a web browser in a background processes and login to the Quickbase account, then navigate using the little XML knowledge that I have.
I just can't find a good way to do this. Any ideas or can give some help on the code to do any of the ideas?
I have to write a program for a user to take a 20 question test (A, B, C, D). The users answers will be stored in an array and compared with a 2nd array that has the correct answers. Its then supposed to go to a 2nd form when you click show score, grade it, and display whether each answer was right or wrong. I'm missing something easy probably.

After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.

In the examples they seem to initate a new array in an existing object but I can't figure out how to do this in VB?The example shows the following (C#)

View 3 Replieshow to write the code for my project.I am to base my new project on an existing one(existing one has code that works 100%)and create an Array of a structure that bascially holds the information from a summary form AND the totals from an AddToOrder_Click event. If you are still with me)... I cant figure out what the code is for my structure and Array so that I STILL have a Summary Form but I have an array that shows when I click my PrintPreview. So an Array is basically a "space" that holds information, like my summary form except it doesnt show until I click PrintPreview right?
If I just wanted to show the table then my code belongs in the PrintDocument1_PrintPage to show the array but the actual structure code belongs in the Click_Event of my AddToOrder? Please Please understand I AM NOT asking for anyone to write my code, basically I am asking for some clarification on what exactly creating an array from a structure is and therefore determing where the structure is to be placed in my code..
I'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click

I have an array of type Double() (1 x n) that I am trying to quickly plot on a graph I've already set up. The only thing I want/need to do is take my array and store it as data points (y-axis values) in the series I already have. What's the best way to do this? Also, will the data points that are plotted change as my array changes, and if not, how would I replot those new points and get rid of the old points?

View 7 RepliesI am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

im wondering whether you can split one variable according to its characters e.g.

View 3 RepliesOk so I have an array and wish to add the variables of the array to separate lines of the list box. I came across this which in some ways worked but also didn't. The second thing mentioned on the page was to us:
ListBox1.DataSource = Form2.Title This works the first time you run it but if you try to run it again nothing happens. So using the above or something else how can I get it to update the list box? Another thing I tried was to use the DataSource method but instead to clear the list box first, but that turned up an error
