I have a problem with snake game. I never tried to make a game with VB, but now i tried to make snake from this tutorial:So i added food to this snake game, and when i taking food, it increases score, but length cannot be increased and i don't know why. This code is in timer to check if snake head is on the food:
If p(m).X = food.Location.X And p(m).Y = food.Location.Y Then
score += 25
food.Visible = False

I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}
Dim rateIncrease As Decimal
Dim isConverted As Boolean

Still working on that overlay. I am stumped on what I think is my last function. I have a + and a - button that needs to control a text box that has numbers in it. For instance: TextBox1 shows the number 2 in it. When I click the + button I want it to increase that number by 1. It sounds too simple when I say this out loud, but I think I am stumped with this basic function. I don't know where to begin.

When new record is added, I want the vb to look at the last record in the database, look at its id, add 1 to it (+1) and generate a new number and display it in the IDTextBox.

View 7 RepliesI have an array in my application and I don't know how many values there will be in the array because it gets the data from a webpage. Filling the array with information from the webpage works except for the length, it always returns 999. This is my

Array = GBA(source, "<b>", "</b>")
Count = Ubound(Array)
How can I find out the length of my array?
I have an API that loads into memory from a button click. It can then either load an approx 10MB txt file (ASCII comma delimited characters/decimal list as a string) or live timed data from the internet. The idea is to be able to view the data in a text box. From there I can see what I am doing as far as spitting that info into a datagridview or database. The data is completely out of order in the txt file but has various Getinfo Functions / DLL's accessed via button clicks that split the data into its correct format to display in the text box. The problem I am having is not having fixed length strings in VB 2010. I don't know enough to work out if there is a simple work around or something more complicated required. Everything I have tried has left the textbox empty.
VB 2005 code that works:
Option Strict Off - I want to solve with this ON
Option Explicit On - I want to solve with this ON

I am pretty sure that my questions will soon get so annoying you won't answer them, but before it happens.I am using DrawCurve (with density set to default) to draw on my picturebox. I need to know the exact length (well, not *exact* but knowing it is around +/- 1px from exact length would be nice) of the curve drawn.
Is there any function in API I could use to get what I want? If not, could you point me to the algorithm (preferably implemented in any language) that I could use with array of points as an input and length as an output value?
I have a title (in one line) that can have different lengths. I need to print this title on A4 landscape - page ( draw string in print page event), but always it should be located in the middle of the page, regardless of length. If I want to determine the exact location I have to calculate the length of the string in pixels. Or maybe there is a better way to center the string on page? How can I do it?
View 2 RepliesThis is related to my last question.Even though Access considers Nulls and zero-length strings (ZLS) separate values, often developers wish to treat them as equivalent for the sake of an If...Then statement or some other stretch of code. One way to accomplish this is to write code like this:
' Not so efficient
If IsNull(varAge) or varAge = "" Then
' do something

I'm trying to make the classic Snake game in VB.NET, but if I hold a key (any key) during the game, after a few seconds the game freezes until I release the key. I've tried lots to fix this, but nothing works, maybe because I don't understand the problem.I'm assuming that when I hold down a key, the Form1_KeyDown function gets called, and when, after a few seconds, the key goes into "I'm being held down" mode, that function is constantly called, so the timers don't get a chance to update. But like I said, I'm probably wrong.
I've been struggling with this for a while. I think this is all the necessary code, please let me know if it isn't.

I am currently in the process of making a snake game using VB.NET... I was just wanting to gather ideas on how to do the body of the snake..Currently I have a class called SnakeBody which contains the following code:

I guess what I am asking is if Dim body As PictureBox a logical thing to put in my class. As in, I am not sure if that is the correct thing to do? To create the actual body of the snake I will have an array of these SnakeBody objects. If `'Dim body As PictureBox is valid How do I reproduce the same picturebox everytime my snake eats something?

View 10 RepliesI have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

View 1 RepliesI am creating a math related class and one of the problems I have been having was how to create a function to return the fractional part of a double as an integer. I could easily do that if there was a way I could get the length of the digits.

-0.125 should return 3
-0.5 should return 1
-0.4545 should return 4
I would like to do this without using string manipulation. So far all I have gotten on the web is unanswered questions. I thought of using log, but it doesn't give the desired result when working with numbers < 0

By my logic, this should only assign .length to index IF the length of strItem is longer than 0. This check is there in case the listbox is empty, or the user has not selected an item. However, everytime I go through this code without an item selected I get:

I am wanting to create 2 tables called Stores and Locations. Locations is a table containing a unique location_code and a location. Stores is a table containing a unique store_code a store name and a variable number of location_code's and a relationship is set up between the 2 tables.
creating the Stores table in particular the location_ code. Can rows in a table have differing numbers of columns? as a particular store type could be in many diferent locations. I feel it should be possible to set up some sort of array of Location_code's in the Stores table.
I am setting up a snake game, I just like to know a few things. Do I require a GRID? and the grid needs to be the same size as the square obviously but how do you go about moving the snake to the square. I mean why do I even require a grid? Why cant I move the snake by its own size. Just need some clarification of the steps I should take to make my snake game. I would like to do this from scratch.

I need to seperate a name into 2 parts using split the first part being 2 letters "That was easy" but the last part of the name would have an unknown lenght. so how do I get the unknown length? I believe I understand the Join Part here is what I have but it only works when you know the lenght of the name
