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.
I am looking to create a startmenu like thing in my game, I have my 'desktop' all sorted out but struggling to create a startmenu that I can easily add stuff to via code. For instance when the form starts it will check a directory for DLLS, query each dll which will return a name. I then need to populate this menu with the 'installed' applications my game has. I have a start equivalent button then I just need to the actual menu.

View 2 Repliesi want to declare an array with a name that is the value of a variable. I need to do this because i want to create arrays from a text file that i'm reading.Basically, if someone could make this work then i should be able to change it to fit my use.
Dim var1 As String = howdy
Dim var1() as Integer
In this case i'd like to be declaring an array with the name 'howdy' that stores integers. In reality i'm looping a bunch of read names and would like to create an array for each name i read- but i'm quite capable of sorting the rest.

Why I cannot get a variable to come in. I keep on getting the error "Expression does not produce a value" for one of my Dims.

So basically, how can I create a variable from something that has yet to be created?
how do I DIM a variable's name using previously declared string varialbes? I have been using PERL for processing data stored in text files but I now have a business need to use VB2008. I would like to do something like this:
dim name1 as string = "ABCD"
dim name2 as string = "123"
'here is the part that I don't know how to do - create a 3rd variable name concatenated from name1 and name2:
dim string.concat({name1,name2}), or maybe use a counter in a line like 'dim namex as string' with x being a counter value.
Essentially I want to dim variables using text strings extracted from a file. In PERL I have declared literals and arrays, such as 'my @$name1', which creates an array named with the contents of $name1. In VB2008 I am not sure how to make this work with the DIM statement.
I have got a bit of code which creates an error when you start debugging. the code is:

This code is a declaration (outside of a sub) so that it can be used in any subs I choose. I don't know why this causes an error?
Is it possible to create a variable that is global for each session in ASP.NET? Usually I do this with Session:

I'm trying to elaberate on some basic examples of .Net programming in using VB. The basic example of creating a new instance of Form1 is:
Dim x as New Form1
x.Show
I've added some OptionButtons to set the StartPosition of the Next Instance of Form1 as well as some Labels that display the Top, Left, Width and Height properties when the new instance of Form1 is Shown.
This is the code I'm using.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim x As New Form1
If Me.RadioButton1.Checked = True Then
x.Top = 0

I need to store elements in a multidimensional array. Specifically, I need to save "tiles" to a grid (e.g.Grass at x:2 y:5, Dirt at x:3 y:5, etc.). Using a multidimensional feels very hacked up and is very glitchy (having to resize my arrays and having to create new ones were they are non-existant). Is there some kind of element made for this? Something I can say obj.getPos(2,5) and get my Grass Element and use obj.setPos(DirtObj, 3, 5) to set it to my Dirt Element?
I'm just wondering if there is something easier to use than multidimensional arrays in vb.net, that is all.

In my classic asp app, I have a markup page with a bunch of checkboxes. The checkbox control ID is bscv.Once a user checks a box and clicks submit, the value is processed on the next page called next.asp.Based on the value of the checked box, I display the correct dropdown.I use the following code on next.asp to display the correct dropdown.
If bsvc = "master" Then
' only master was checked
' "If the user checks only master checkbox, ...txtmaster with 2 options... is displayed."

I need to modify a xml file (actually a .rdlc report file) and add some nodes which have a lot of children nodes (and those children nodes again have children nodes). Actually they are almost the same strucutre, like this one:
<TablixRow>
<Height>0.23622in</Height>
<TablixCells>

and it will add my specified NS. (like I said, XElement.Parse(string) won't add it) So now I can construct the correct node. For my second problem I still can't figure out: I can't navigate to the target node by using the element name since it won't search for correct NS.

I am developing an automation tool which is reading the file path from an Excel workbook and after launching the application I am firing print job using SendKeys.SendWait() for Ctrl+P and Enter key. Now the Problem is, I am facing synchronization issue for launching the application and handling the print procedure keys.Sometimes Applications are launching little late(like Excel and MsWord files), so at that time I am not able to find till how long I have to wait for a successful launch of the Application. Anybody have any Idea how to check this waiting time till how long I should wait to fire CTRL+P and then after getting PrintDialog ENTER button ?
View 2 RepliesI've got a listview with a bunch of items which all use checkboxes. Each time an item is checked or unchecked I want to save the selection. Whilst saving/loading the selection is not an issue, I can't seem to find an event which triggers AFTER the checked item has been changed. For example, the ItemChecked event will fire when an item has been checked or unchecked but the event will give it's checked status BEFORE it was changed. I've had to resort to saving the list when it loses focus but this isn't ideal.
