View 2 Repliesim working on a project that is calculating the total population for given countries and its in the hundreds of thousands. And i need to output the population with the ,'s in the appropriate places.Ex. population 123456789 i need to output it in a listbox as 123,456,789 so im looking for a converter function or something built in that takes my value

I have data which can be put inside listboxes, I then proceed to save the data into a textfile then attempt to load it. This all works great until a number of over 1000 appears because it's read as 1,000 and VB thinks the Comma means to go onto the next field.

View 1 RepliesI made a program that generates random numbers and places the numbers in two separate labels.How can I make the number in the first label greater than the number in the second label.Here is my code for generating random numbers:
Dim nRandom As Integer
Dim nRandom1 As Integer
Dim randomgenerator As New Random[code]....
I want to make the first number greater than the second because the numbers should be subtracted .
I am making a little application to provide a simple GUI for editing controls for some old games that use INI files to store their config.I have just come across the following ini file key but I can't see how it is storing the controls. It is meant to be for an NES pad, which has 8 buttons - Up, Down, Left, Right, Start, Select, A, B.

I'm back again as I'm waiting for the coffee to kick in and have another question that seems to be not causing my brain cells to fire correctly.
I've set the following code to determine the line numbers of all rows returned from the procedure loop.
linenum = 0
Do While (rsData.Read())
linenum = linenum + 1
loop
Now I'm trying to code a button that will move users to different sections depending on the linenumber returned.
So if there's only one linenum with a value of 1, they get a button to 'Apply'.
If the total linenum values are greater than 1, they get a button to 'select apply date'.
Now again I'm having a brain fart and can't think of the logic if theres a linenum of 1+ how to determine the button should be displayed. It needs to include the value of 1 as well as there are more than one linenums so the button should display the 'select apply button'.
if this is a dumb question. I don't ever have to write anything in VB.NET.But I am passing variables named "name" to a function and sometimes it may be 1 name or 2 names, etc. I want to check in the function if its only 1 name don't add a comma, if it's 2 names add a comma. Is there a way to get how many "names" there are?
EDIT: Added my ode to make my question a little more clear. sorry for not doing it before.

View 2 RepliesI have a variable called VarNUM which stores a number from 1 to 10. What i want to do with this is based on the current number stored in that variable call a different set of variables from a module with Public Structure ITEM1. It has the same set of variables for ITEM1 - ITEM10 but with different values. So ya in raps how can i use the number in one variable to access a set of different variables? Something like ITEM(VarNUM) then the set of variables that all have same name but with different values so that i dont have to go,
Code:
if VarNUM = "1" then
name = ITEM1.name
store = ITEM1.store

View 5 RepliesI have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:

Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command

I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.

We are currently using for next statements in the class. I know how to prompt for and utilize the numbers that are input etc. My problem is the EVEN numbers part. I obviously have to determine if the number is even and then use a step value of 2 from there. But not sure how to determine if number is even or odd (guessing to use mod, but totally lost).
