Array Values - Add 1 To The Value Of The Name Of The Food Each Time It Is Selected By A User?
Feb 13, 2009
i am coding a program in vb.NET, it will be used for people to vot for their favourite food.I have let the users input the name of favoutie foods into an inputbox and tehn store the name of each favoutie food into an array called foodarray. Then the array outputs each item inside it into a checkedlistbox, which will be used to vote from by the voters.The problem is that i want to add 1 to the value of the name of the food each time it is selected by a user. How do i do this, i want to add 1 to the names in the foodarray to find out how many votes each food gets.
My sister owns a small business, and (as a cashier) she is currently using hand written invoices for receipts and records. She knows I have some basic programming knowledge, and would like me to make her a program that would make it easier on her. Ultimately, it's going to log sales, and anything else to make taxes easier on her, which she is also doing manually at this time.
That will probably be a few weeks from now, for now what I want is to be able to have a Category, Subcategory, and Product system using ListView boxes. Ie. In the first ListView will be general categories, ie "food". Under the category "food", there will be the subcategories "pizza", "fish", and "pasta". Under the subcategory fish, there will be the products "salmon", "trout", and "cod". The user can highlight cod, click "add item" twice. The first time adding it to the receipt ListView box with a quantity of 1, the second time changing the quantity to 2.
Now the idea here is to make the contents of the ListView boxes depend on the selection in the preceding ListView box. If the user chose the Pizza subcategory, he would have the products "cheese", "pepperoni", and "mushrooms" in the product list box. If he chose "beverages" on the first ListBox (general category), he would get different choices entirely.
Of course these are not the items being sold, but they serve as good examples. I have a decent start on the program but have run into a few roadblocks. In each ListBox, there will be an "Add *" selection (activated by double click), which * will be the ListView it in. For example, they could go to the food category, double click the "Add Subcategory to food category" list item, bringing up a dialog asking for the subcategory name. They could then, in that subcategory, double click an "Add product to * subcategory" list item, bringing up a dialog asking for the item name, price, and flags such as taxability (some things such as services are non taxable). In addition, I want the user to be able to double click an existing item, removing it from the list.
I have a good start on the program, the interface is mostly done. My next step is to create some form of database to store the categories, subcategories, and products she adds. I could probably get it to work in runtime, but it would be a shame to have to redo it every time she restarts the program But this is where the roadblock is. I don't know what to do at this point, I've spent hours on Google before coming to this site. I will include the source so you can see where I'm at, at the moment.

I am executing the sql query to fetch values and showing it in my datagrid..and when i do that it works perfectly fine...and problem is that it takes 10 min for my datagrid to fill...so in between i want to show the execution time to the user in another form till my query processing completes..

I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.
I'm creating a BASIC application, and I can't figure out how to save a user selected file (FolderBrowserDialog) to a location selected in another dialog (SaveFileDialog).
I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
I am upgrading user control from vb6 to vb.net.In the vb6 application I am loading 3000 labels using a label control array.In vb.net I am doing same but it's taking too much time to load.In vb6 it's taking 1-2 seconds, but in vb.net it's taking 30-40 seconds for same work. Why does it take too much time in vb.net for same work?Code is given below, here Led is the label control array.
For l = 1 To 3000 Led.Load(ledCounter) ColLed.Add(Led(ledCounter))
I'm making this POS software for a restaurant and I was wondering what the best way to create the button interface for the items since it's going to use a touch screen monitor. I was thinking of adding the buttons at runtime to solve the excess space problem, and also add the code at runtime, but that seems like too much work, so I thought I should ask if there are any other ways to approach the problem?
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93 Year 2: $2,724.32 Year 3: $4,350.76 etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue Private Sub btnCalculate_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalculate.Click
I have an array of people stored in a custom structure array... how can i copy this array to a temp array so that the temp array has all the same values as the original custom array?
I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.
to trace the days of a program installed in user's computer.However, the user can changes the system time of his computer to a advancing date. How can I get a SNTP time from internet to solve this problem?
I want to be able to see if the values a user inputs into 2 textboxs equals the values assigned to a picture. I put these values in the picture's name and tag. Also the picturebox is getting the image from a random function correlating to an imagelist. How would i go about thisI thought of maybe using a checkbox and coding
If picturebox1.image.tag = ("12") _ and textbox1.text = 1 _ and textbox2.text = 2 Then checkbox1.checked = true
unfortunatly when i debug it says the picturebox1.image.tag = Nothing
I am creating a maths programs that draws graphs for the user. so far i have placed 22 values into an array and now i need to import them to excel, draw the graph and import the graph back into the program to display them.[code]...
I am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
I have a winform with richtextbox. I want to get the user input values in any window like chat programs(msn,yahoo,gtalk), Ms Word,...etc, and set the values into richtextbox?
Per this UserControl that can be added to a blank form, I would like to use the HorizUnits array below to map custom grid x coordinate from a mouse x position.For a given input value 13, what syntax would I use to obtain a value of 2 where 13 lies between Value 10 and 16 for which 2 (Name) would be the custom grid's displayed coordinate position?
I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".
Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?
writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.
then, in a 1D array I store the player's numbers, simply as
0 23 1 16 2 19
[code]....
I want it to take each number from the player's number array individually and compare them to each row individually in the lotto results array i.e. the first six cells in each row in the results array will be compared with each user number to find any matches, if a value matches then a count is incremented. if the count is greater than 2 but i'm getting no where with it :( i've been trying to use the For To loops but keep getting index out of range, or else nothing is happening at all!
I am writing a pizza order program for class and have gotten everything put together, even got my array setup and displaying but when i go to calculate it will not calculate the values coming from the array in any of the calculations.
