Write an application that prompts the user to enter the size of the side of a square, then display a hollow square of that size made of asterisks. I have seen javascript using this but nothing with Visual Basic.
View 1 RepliesI am trying to build an oscilloscope; I will be using a signal coming from digital encoder going through MAX232 logic level converter to the PC via the serial port 1. The signal from the encoder is 3VDC when it is high and 0VDC when it is low, the encoder resolution is 1024 PPR, the encoder is attached to motor (1800 RPM) so the max resolution is 1843200 pulses per minute or 30720 pulses per second. I would like to make my form display the changing of the input from the serialport1 to graphical display just like the digital oscilloscope. I
I want to be able to display the signal as on and off (square wave) from the encoder and be able to display the signal as speed so when the motor is running at full speed the line be at the top of the graph and when the motor drop to 20% of its full speed the line will drop to 20% and so on.
I'm trying to display the square root symbol on a button in a windows form. I'm using the unicode U+221A which on windows character map is the root sign. When i enter this in visual basic ensure the font is the same as that in the character map (wasn't sure if that made a difference to the unicode) my button displays the eta sign instead. Any help greatly received.
This is the code i'm using to set my unicode the the buttons text property.
btnSquareRoot.Text = CChar("U+221A")
Trying to create a program that accepts a square array size 4 by 4. Then it should print the totals of the rows and columns. I started with a form and made text boxes and created a print button. I made it so that numbers can be input into the boxes. When hitting the print button, it should print the totals of what was input, however, it isn't doing that. Is there a different way to write the array code so that it will print it? Should i not have text boxes but rather have labels with fixed numbers set in them?

So i want to apply gradient to a square, a center to edges gradient. This is the code:
Public Class Form1
Private Sub PicSourcefrm(ByVal sender As System.Object, ByVal e As PaintEventArgs) Handles Me.Paint
Dim Graph As Graphics

NOTE: Picsource is just a PictureBox named that way. If I put "BrushSquare.SurroundColors = Color.Red" in a comment. The program works but the edges are white, not red like I want them to be.
Is it possible to create a square using graphics that will not show in VB.NET? I want to use it for the IntersectsWith function to detect moving rectangles that are around objects.
View 1 RepliesWell, the code I have only gives the the number IF its like 2 x 2 or 4 x 4 is in the text box (4 or 16), but if its a number that can not be multiplied together to get the value in the textbox, it has an arithmetic overflow, what can I do to make it work for all numbers?
Dim Value As Integer

View 1 RepliesI need to take a minimum and maximum value from the user for length and width using an array(s) and display the square feet of all values. Since the values can be any number the array(s) size cannot be defined. In my form I have 4 text boxes (MinWidthTextBox, MaxWidthTextBox, MinLengthTextBox, MaxLengthTextBox). I have been able to take the text from each text box and initialize 2 separate arrays with those values, however I am completely lost on how to get the square feet from each element. In other words I don't know how to do this:
WidthArray(0) * LengthArray(0)
WidthArray(1) * LengthArray(1)
WidthArray(2) * LengthArray(2) etc. etc.
I don't know if that is possible or if I am over complicating things.
Here is the code I used for my arrays:
Dim WidthArray() As Integer
Dim LengthArray() As Integer
Dim MinWidthInteger, MaxWidthInteger, MinLengthInteger, MaxLengthInteger,
[Code]......
In each For loop I can output the elements to a listbox for text and it works but again I have no idea how to multiply each element to one another to get square feet. Should I be using a multidimension array instead?
I have a picture that is the map of a circuit [URL]. Now I want a Square to follow that circuit. I have tried some things but I couldn't get it right. How would you start? And how do you access the color values of the "line" to follow it with the square? Or is that even the wrong way to do it?
View 10 RepliesI was wondering if it was possible to somehow use (or import if I have to) the square buttons that you sometimes see as the default System button on older Windows computers, and use it instead of the new Windows XP rounded kind with the white background.
I tried looking here to simply make the square button myself: [URL]But it makes 0 sense to me.Also I don't want Flatstyle as it makes the button 2D and I want the old square but 3D buttons, like the OK and Display button in this picture.[URL]
