Ripple Tank In VB2010 Forms?
Jun 13, 2011
I'm attempting to make a ripple tank such as this in VB 2010. I'm not trying to make it as complicated as that, at the moment I am making each wavefront from an.graphics.DrawEllipse.The problem I am having at the moment is making the ellipse expand properly. I'm using a timer to add one the the ellipse's radius on every tick. Another problem following that is how to make it continuously fire wavefronts so that more than one is on the form at a

I have created a Windows Form inherited from an existing form using the Inheritance Picker: Project menu ==> Add Inherited Form.So now I have the Form-base (FrmP1) and the inherited form (FrmP2)The form works perfectly. If I open the "code" window of FrmP2 I can see only the main class:
Public Class FrmP2
End Class
I have added now a FormClosed event in P2:

I am making a visual basic game. And in the game I have a few instances where I want to call open a window (let's save to save the user's preferences) from a form, then I want to go from that form to another one.
Example:
The user has completed the new game page. I have the users choices in a host of string, integer, and boolean variables. Now I want to use a generic saving screen I made with a progress bar. When I open up the saving box, I want to close or hide the new game setup menu (whichever I need to do). Then when it is done saving I want the Saving bar to return and cause the new game form to open the actual game form and close itself.
So I guess my question is this: What is a reliable(or correct) way to poll for a return in form to signal it to go ahead with execution?
Second:
This is similar to the first question. Instead of keeping the first form open when I use the saving form; is there a way I can save the name of a page I want the saving bar to go to once it's done?
I want the user to enter their prefered username before they start a new game for the first time. So I poll the saved username setting I have and if it equals "username" I want the Username entry form I made to pop up, but once it's done I want it to immediately call the new game screen. I also want to use this username entry form on the options screen so that the user can change their accepted name at anytime; but I want this screen to return back to the options screen.
What is the accept way to do this? Is it done through stacks? (form information -> stack : load new page : Do stuff: load stack value -> goto)
Finally:
Do I have to keep a window open (not close it) to access the variables that I have defined in it, and have stored values too? Does this apply to hiding too?

Most conversion tools will still use VB6 syntax And so don't many people coming to .NET from VB6 - drives me nuts.Rewrite your program from scratch using all .NET syntax and not legacy VB6 syntax still supported in the .NET world.

I am creating an RTF file programatically so that user input can be formatted and I can control the font.There's two problems:
1. vbNewLine doesn't seem to work. I've also tried vbCrLf and that doesn't work either. I just want to introduce another blank line and not sure why it's not working.
2. Is there a way to use tab print positions to format things so they're not all just aligned left, center or right? (like tab(20); something etc..)
Here's my code:
Public Class Form1
Private Property richtextbox1 As Object
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim something As String

I have a simple for loop with the following code
For i As Integer = 0 To 4
Snake(i).X = (120 - 20 * i)
Snake(i).Y = 120
SnakeBody(i).Location = New Point(Snake(i).X, Snake(i).Y)
Snake(i).Facing = 3
Next i
But for some reason I unable to debug it. I place a breakpoint on the line Snake(i).X = (120 - 20 * i) and When I try to see what the values are the second time the loop iterates it simply exits the loop.

I have a DLL that I made in FORTRAN to do some number crunching. It works in VB6 and in VBA within Excel. But I cannot get it to work in VB2008 or VB2010. If I try to access it the subroutines in the DLL I get either, 1) Structure of DLL invalid error or 2) Cannot find the DLL error.
Here is my VB2010 code for a smaller demo app that came with the FORTRAN development system. Again, this works with VB6 and VBA but not with VB.net
vb.net
Imports System
Imports System.Runtime.InteropServices
Public Class Form1

I created a program using VB 2008 to aid me on design work-related calculations that uses Access mdb file for displaying info. and calculations. But I experienced an alarming problem when I converted it to VB 2010 The program execution works in VB 2010 but it can't display the data from an mdb database file.
To simplify and simulate the problem, I created a simple identical program in VB 2008 and VB 2010 showing a window that displays a data extracted from an mdb database file. Both programs run as intended in each environment. When I open the VB 2008 created program under VB 2010, VB 2010 converts it and when I run the program, it doesn't display the data at all.

I got this code by recording macros and transferring the code. Everything after the "=" sign gets the error "is not declared. It may be inaccessible..."
eg .LineStyle = xlContinuous The error items are shown in itallics.
I sure would appreciate some code that opened current worksheet, write to the worksheet and do just those formats that I mentioned (cell color, border).

i am trying to make a webbrowser in VB2010, but one major roadblock that has been in my way for a while, is the fact that i can't get my bookmarks bar to work
i have no code to show you and i am completely open to ideas as long as i use a toolstrip just make sure that the bookmarks work and they are Saved when the program is closed and opened again.
Notes:
instead of "WebBrowser1" use:
"
CType(TabControl1.SelectedTab.AttachedControl.Controls.Item(0), WebBrowser).PutWhateverHere()
"
(i am using a dotnetbar tabcontrol so i need the "AttachedControl")
the toolstrip i am using in this case is called "BookmarksBar" so please don't use "ToolStrip1"

Trouble is the application install folders are not always the same from one machine to another.I am able to read a registry key that gives me the path to the DLL.I've done a lot of Google searching and have found the"References.AddFromFile(filename)" function but when I try to use this in VB2010 I get an error message saying "AddFromFile is not a member of VSLangProj.References".

My project that I had built used spreadsheets and charts within the forms to provide the user with the necessary data. This worked fine for VB2008 as it had all of the ActiveX office web components built into it. It seems that VB2010 has a different set of base components and emphasis office 14.0. I was wondering how people have gotten around this or if they can. I tried using DataGridView, but it doesn't seem to be able to do what I want to do. I need the ability to have users enter data into a table and then use that information to be able to build graphs real-time based on their data.
