I have to make a lot of retangular boxes to make my program neat but i'm having a problem of adding boxes. I tried using the draw event in the tab page but everytime i scroll it will draw the lines again and messes up everything. Also when making a line greater that the tab page, autoscroll won't work.Is there a way to make lines or boxes in design time?

View 2 RepliesI'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.
View 10 Repliesam having a big problem trying to make a program that will add multiple text boxes together.What I need to do is add all the text boxes together. If it is less then three leave it alone, if it is more then three then put a 10% discount on it. There are also other charges but the main thing I'm struggling with is adding the text boxes.
Here is some of my code:

I am writing an application that is talking to a PMAC card control servo motors. The motors run in an x,y plane where 0,0 is lower left. I would like to be able to draw what I am about to send the card on the screen. All I have are lines and arcs. I have had no luck getting the top left origin to change, or my arcs to draw correctly. Is there any libraries out there that would help with what I want to do.
View 5 RepliesI'm using the free version on Visual Basic 2008 (through school).The assignment is to populate a list box from user input text. The textbook only talks about populating a list of known items.ex animalListBox.Items.Add("dog") Which works just fine, however, we don't know what the user will input.
So, how should I be thinking about this?
Adding text boxes to a form
View 2 RepliesIf I'm trying to output to a listbox, what is the easiest way I can enter a string and then a variable on the same line? I'm trying to use listbox1.Items.Add(...). Obviously outputting a string is no problem and outputting a variable is no problem, but I want to add a string and then a variable after the string. For instance:
name = "Joe Smith"
listbox1.Items.Add("Name: ", name) [or something like this]
[Output] Name: Joe Smith
I am building a very basic calculator which adds and subtracts various numbers from various text boxes when I click on the 'button'. This works fine with:
TextBox3.Text = TextBox2.Text + (TextBox1.Text * 1000)
etc but when it comes to adding or subtracting time I get completely lost.Say I want to add 50 minutes in one text box to 12 minutes in another to display 1:02 in a third text box by clicking the same 'button'I am using Visual Basic (in visual studio 2005) to program a Windows Mobile Classic 6 PDA?

I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.
The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.
Form1 has 2 public string variables defined and initialized to "" (an empty string).Form2 has 2 text boxes and a button. When the button is clicked the public variables on Form1 get set to the values in the text boxes.This works fine.I recently had to add a module to my project so that I could use Main as the startup item. Ever since doing that the above no longer works.The variables never get set to the values in the text boxes. They just stay empty.My Main code is simply this for now:
Dim f As New Form1
Application.Run(f)
i have a problem that wants to display a random series of coin tosses(coins flipped per each user click)i can't get the picture box to display the coins

it should count the number of time the "toss" button is pressed and display that number as welli also need to add a flip module that doesn't take arguments and displays false for tails and true for heads, but i'm stuck

View 1 RepliesOk, Im having trouble passing a value from one form back to another using a listbox... The user clicks a button in the main form to bring up an instance of another form (form2.show). In that form, the user then then selects a number 1-5 and then presses done:
Code:
Private Sub frmPlayer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x As Integer
If lboNumber.Items.Count = 0 Then 'list box is empty
For x = 1 To 5

How do I pass that value back to the main form as a value when the user clicks done?
I'm currently trying to make a beat generator, which allows you to add several labels (boxes) onto a panel, and then sound will be played when the "play slider" reaches the same x-value. However, i can't make the slider find the boxes. OK, so this is what I've got so far! Clicking my button, a label named sound0, sound1, sound2 is added to my panel_back (which is the background of the player) Private Sub btn_addkick_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_addkick.Click

Am currently piecing my programm together and working on structure. My plans will have me running multiple forms,and my question is this. When I have ,say ,on form1, a "TextBox1" and on another form a TextBox with the same name,will I have conflicts when I access data across forms. Should I be taking care to make sure textboxes and buttons names aren't being repeated,or will VB know what I want?
