I've got everything working except this one problem which I can't seem to get my head around.I've made a function that returns a random number between 1 and 11 (how many invaders there are on a row).I've managed to get this to work, however the invaders will keep firing even if they are visible, so I made a do until loop which says to keep running the random number until it finds an invader which is visible... The problem is that if the whole row of invaders aren't visible, it will get stuck in the loop.
Been given an assignment to create a space invaders game. Although there's a long way around, is there a way to make my code smarter.Here's the section to make a row of invaders so far:
Public Class Form1 'number of invaders in a row (horizontal) Dim numberofinvaders As Integer = 11 'set of invaders (vertical)
[code]....
So what I want to do more precisely is have the value of setofinvaders to change how many rows of invaders vertically in a loop.
Im creating a space invaders game that has a group of "invaders" moving side to side and when i shoot one it gets destroyed, my invaders are in an array. So in order for the invaders to keep moving right until they get to the edge, i made a function that detects which invader is right most. But this was crudly done as I wa trying to make the opposite of my left most function which works. So my rightmost function dosent work
I'm trying to make a space invaders rip off, and I'm currently stuck on how to make the missile fire from the center of the player's ship. I have the missiles all in a control array, and they move up the screen fine, they just dont start at the x point of the ship, they start on the left margin.
Dim Line As Integer
If Missile(0).Location.Y < 391 Then
Missile(0).Location = New System.Drawing.Point(Line, Missile(0).Location.Y - 5)
I want to make a simple 2d game in Silverlight, but it seems like things have changed since the last time I tried to make a game using mode 13h graphics. Can someone give me a run-down of how you'd go about it.I just mean at a high-level, focusing on the silverlight-specific aspects; not general game design.A fictional example might be:'The main game loop shouldn't be a loop, use a DispatchTimer instead. Use a Canvas as the main drawing object; but realize that we don't bother drawing individual pixels - all of your in-game objects should be represented by controls. Be sure to set the 'UseHardwareFlag' to true'.
i'm not very familiar with GDI+, but i managed to create some basic functions of Space Invaders game i try to develop in Compact Framework. I have problems drawing the images (Spaceship, bullets, enemies). The screen is flashing a lot. I use a buffer bitmap in which i draw images to the new positions, and i have 1 line of code that just draws the buffer to screen
[Code]...
i use me.Invalidate inside a timer so every 50msec the game redraw the screen with new positions. Why the buffering does not work?? It can't be the emulator that i preview the program, it is flashing A LOT. Is there any similar code / project that could help me? i'm tring to find a similar project for COMPACT FRAMEWORK but i only find C++ .net examples. i need VB .NET COMPACT FRAMEWORK examples
What I mean by "Checking ".left" of whole object" is making something happen if, for instance, a label were to hit an object. Instead of it needing to hit at the objects exact left, it could hit anywhere on the object. Bit confusing...I know...here is an example...
i am currently trying to make an invaders-like game with visual basic 2010.I've managed to make one alien (picturebox16) dissapear when the coordinates of the arrow (picturebox1) kinda matches the coordinates of the 16th alien, however, the second alien(above it) doesnt dissapear(picturebox4)?
I am writing a message system on my server, the xml is something like this
<xml> <entry> <sender>[code]....
my problem now i guess is 2 fold, i wish to combine the first 3 queries into a single query and place in a list or a collection or is there a way to do this with a single query that will give me my desired result?
How would i get a certain text inside a textbox to equal that text space to space or null to space?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If Textbox1.Text.StartsWith(Textbox2.Text + " ") And Not String.IsNullOrEmpty(Textbox2.Text) Then Textbox1.Text = Textbox1.Text.Remove(0, Textbox2.TextLength) Textbox3.AppendText("a") End If
Btw: after i finish this step my project will be finished!
I've written an application and I'm trying to utilise a database behind it. I've created a mysql database, and table which all appears to work correctly. I appear to have connected to the db correctly too. And hit a bit of a brick wall. As a side-note, within Visual studio connected to the database using the add data source wizard, I then dragged and dropped my db table's column onto my form that intends to display them all (6 textboxes, including primary key) and that now displays the first record of the table. It confused me, because i did this as soon as I had setup the database with no visual basic code assisting, so there wasn't even a connection string?!
One functionality i want to have is to press a button and cycle through the table's records using the form by the unique id, how would I do this? I'm essentially asking how can I enter a number in a textbox which would then return me the relevant primary key and data attached to that record.
My project contains a DataGridView with a SQL Database Table called Shows. This is a list of TV Shows and I want to apply several filters to it. So I have several different columns to apply the filter to.
Currently I am using RadioButtons to switch between the queries, but I want to be able to have several filters applied at the same time with CheckBoxes.
I'm a PHP coder normally, but I've been asked to make a small vb app. I've created my sql db (MSSQL) and have got all the data in it. However, I have no idea about how to connect or perform queries.
Here's my
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[CODE]..........
1) Am I connecting properly? I created a new database using the dataset option and it has no username or password.
2) I'm trying to list the results, which will be clickable to open a new form with the full details. How would I do that?
Eg: In PHP, I'd loop through the resources using fetch_assoc, and create a link with the id and it's name as the firstname and surname.
I use an access database and some queries return calculated fields resulting from functions in the code module of the database These queries are not listed in the "Views" tab of the query designer when adding a tableadapter in the data source designer
i'm doing a bifid cipher project now my code is almost finish.. the problem is every i put a space the space will disappear when I encrypt take a look at my code
I'm just now starting to work on something that works 'like' an ide, where it will auto space my text as I type. I really JUST started and I'm not sure if I'm even doing it remotely like I should. anyways, what I'm doing is on TextChanged (eventually I'll just do it on newline but that can wait) it gets the contents of the text box, puts each line into a string array, trims the excess whitespace, see's if it has a keyword in it, and then adds some whitespace to it if it does.I know I'm doing something wrong with either my declarations or my error handling. Mostly because i'm not sure how to work with string arrays, can you help me with my syntax?[code]
How can I tell what the size of my program is and how much disk space is needed to install. When I publish the program and install it on another machine it will show up in the control panel but does not show what size the program is?Also when I publish updates with it says something like installing 10mb. Is this an additional 10 mb everytime, I guess not, but can someone explain what it all means?
I'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?
I am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown Select Case e.KeyCode Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)
I have a Access 2003 backend db and I'm using vb 2005 to connect to the db via conntection string. It works ok! I can see all the tables but only some of the queries. Why should some queries be absent? In 1 query I have a user define function which cuts up a string. I've created a new VB project with a new connection but the same result. I've compacted the database with not change.
I am trying to UNION the two queries below without success. Dim ds1 As New DataSet Dim MyConnection1 As New OleDb.OleDbConnection(GetPOWERConnectionString()) [Code] .....
I am trying to perform a search query using drop down boxes with a button named search. I want it to bring up the data that is searched for. I dont know where to start from, i have looked around for some coding and different ways to do it but they seem complicated, this is the bit of ASP that is my weakness, need some assistance and guidance. below is the code for the page;
I'm trying to figure out how to do SQL queries towards an SQL 2005 Express server and format the return value to JSON. I got the queries working using this (perhaps very newbie-like) code;
Imports System Imports System.Data Imports System.Data.SqlClient Imports System.Web.UI
Where can I find informations on which WMI queries are in fact available for .NET interface through ManagementObjectSearcher. The command below returns exception for "Win32_LogicalDisk", but works for "Win32_Environment". Every reference in msdn directs to msdn library, which contains all Win32 and COM development classes (that seems not to be available from vb .net code):
I've been going through a lot of forums and see a lot of mention of ADO.NET and how it's better to use. I guess because it's newer and being maintained with current times?I've done google searches for this, but every time I see different programming languages other than VB.NET implementing param queries with ADO.net, or it brings me to results that have oledb commands again.Is there a good ADO.NET for VB.NET tutorial with parametrized queries?
