I have got one picture box to appear from a random point at the top of the form and move down the screen.
But how do I create an infinite amount of these enemies that will travel down the form?
The only way I know how is to just create a bunch of picture boxes and hide them all, and then each time a timer clicks one of them is visible, and starts traveling down the screen. There must be an easier way.
Is there a quick way of creating child forms? I am going to have 20+ and all the code I can find is this below:[code]Can I not make a subroutine and send the form into it to be made a child form? Something like this pseudo code:Is there a fast way like this available?[code]

I need to make basically a bunch of 2d arrays, that I can access the independant values easily. Like multiple properties As an example:
[code]...
Because later I have to access Value1 in a manner that spells out each independantly. I have used some basic Structures to define 1 property and does something with it. But not 2 properties, and I am out of my norm on creating a Class to do something like this.
I've recently started programming for Visual Basic Express - 2008, and I'm currently trying to make a program which takes a bunch of inputs (Name, Age, x2 score results) and then turns this into an output at the end which varies depending on the score results.
I've stumbled upon a small hinderance, which is that the very final stage which has a Console.Writeline does not appear after testing the program. So, everything else functions fine, but as soon as it gets past the "Console.WriteLine("All pupils have been calculated, the results are...")" command the program closes itself.I'm not looking for much help, just wondering exactly what is causing this to happen. I also realise that my coding is sub-par and is coded in a slightly odd fashion, but I'd rather just get this one to work and use the mistakes from this one to correct my future work.
I am creating a game for my class, it is above the level that I know a bit, but I have learned a lot from creating it.
This is how it it works:
-Every time a timer ticks a picturebox is created and displayed on the form, the picturebox is added to a collection. These enemies then move down the form
-My character fires bullets, and when they hit the enemy the enemy and the bullet gets disabled and removed, but not from the collection
-I have another timer that when it ticks, a random number is generated between 1, and the enemy collection count, so that a enemy missile can randomly come out of an enemy
This all works, but after the enemies are hit and removed from view, bullets still get generated from spots where the enemies once where, so to me that means that the destroyed enemies still remain in the collection.
If I try to remove the picture box from the collection I get an error.
I am creating a game for my class, it is above the level that I know a bit, but I have learned a lot from creating it.My problem is that when my user (doctor) sends out a bullet and it hits the enemy (the enemies are generated into a collection), the picturebox is disabled and no longer visible, but that picturebox spot in the collection for all the enemies is still there.
So when I generate a bullet and shot it from a random enemy in the enmCollection, sometimes that random enemy is one that is already been killed.I tried using enmCollection.Remove(..) whenever the collision with the enemy and a bullet occurs, but it gives me an overflow error or another error.
I've been trying for a day now.Everything in the game works correctly except for this.

I am making a 2D game that has a player (me) that shoots bullets (pictureboxes) and kills other enemies. The problem is that when there are many bullets on the screen it gets very slow because it has to move every picturebox.
View 11 RepliesSo I made a Listbox, and also a custom class called "Enemies". I used a Bindingsource to Bind "Enemies" to the Listbox. "Enemies has three properties which are: "Name as String, Health as String, and Dead as Boolean".The thing I need is when I add a Enemy to the listbox, I want the BackColor of the item to either be Red or Green, depending on if the Item.Dead property is false or true.

I have multiple forms and reports with different print area. Some are designed to print to a thermal label printer and others to department shared printers. Currently the user is able to change the printer in print dialog box and print to differernt printers.

I'm creating a database installer where I have some code to create database, tables, stored procedures, etc.I don't have problems when creating the database, tables and inserting required data. My problem is when my code gets to the stored procedures section.
Here is what I do:I have different text files (database.txt, tables.txt, insertdata.txt, storeprocedures.txt) where my sql syntax is located.I execute every process/text file using the following:
ExecuteSql("master", GetSql("database.txt")) ' Creating 1 database.
ExecuteSql("mynewdatabase", GetSql("tables.txt")) ' Creating 15 tables.
ExecuteSql("mynewdatabase", GetSql("insertdata.txt")) ' Inserting data to many tables.
ExecuteSql("mynewdatabase", GetSql("storeprocedures.txt")) ' Creating 6 stored procedures.
Here is part of the error:In exception handler: Incorrect syntax near the keyword 'PROCEDURE'. "This is the second stored procedure because the variables I get below belong to the second one"

Button 1 is meant to be a submission for textbox1 (i.e. when button1 is pressed, the value of textbox1 is saved and remembered).

I thought I'd give VB a go after developing with C# for the past few months. I'm using Visual Studio 2008 and have imported the VB IDE settings. I'm going through the same steps in VB as I've gone through in C# to create my solution for an n-tiered ASP.NET web application, but the results are unexpected. Here's the steps:
1. File > New Project > Other Project Types > Visual Studio Solutions > Blank Solution .... name the solution & choose the location ...
2. At this point, I want to proceed to add projects as follows by right-click on the solution in solution explorer
a. Add > Visual Basic > Web > ASP.NET Web Application ... name / location of the Web Client
b. Add > Visual Basic > Windows > Class Library.. name / location of the Business Layer
c. Add > VB > Windows > Class Library ... name / location of the Data Access Layer
BUT, as soon as I complete step 2a, the solution disappears from solution explorer. "Show all files" is selected. This happens regardless of the project I create first.

View 2 RepliesI am in the process of creating an array for a set of multiple choice questions but I am having a few problems. I am an absolute beginner at VB and I am creating a quiz that users will select one of three possible questions and then depending on their answer a +1 value will be added to the score. However I do not know where my questions and answers are supposed to go, from what I have read online I have to use (0, 1) format to give possible answers but I do not know how I would make the questions and answers display in textboxes on my form. At the bottom of my code I have also included code to randomise the questions although I am unsure as to if it is correct. At the moment I can run my form fine without any problems but my main issue is to how I will get the questions and answers linked to my textboxes on my form.

Private ran As Random = New Random()
Public intScore As Integer
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
'Turns the message box invisible when start is clicked

Is there a preferred method of creating a file with multiple sections? For example a program for a small retail business that might include different categories of sales, etc.I've come up with a primitive way of separating sections of a text file, which I can read and write right now, but I'm not confident that it will always work. I have a feeling it could produce an error down the road.

I'm creating a twitter account manager using the Twitter API. I have multiple accounts, over 10 of them. I want to automate all 10 of these accounts to do certain things, now the way I started to code the program was so that it would accommodate only one account, and all the codes worked perfectly and were managed by individual timers for individual processes that I wanted done. i could tweet between certain intervals, follow people who tweet certain things without me being on top of it.
Now the problem is that I've been trying to create new instances of subs that I've already created so that I dont have to create 10 new subs with the exact same procedures. I'm pretty sure it's impossible to create copies of subs dynamically or within a loop but it didn't stop me from trying. So question is how can I edit a program that was designed to accommodate and automate only one account, to potentially accommodate over a 100? I don't need codes or anything I need ideas so I can try them, but right now I'm completely blank.
