Show A Textbox Displaying Numbers With A Control?
Jun 20, 2011
I have three Buttons labled "Single" "Double" and "Triple" and four textboxes, one for each button and one to display the results. Here is how it works. Each time I click on one of the buttons, it increments itself by that number...for example if I click on Button with the word "Triple" on it I will get the result '3' in the adjoining textbox. If I click it again the number will change to '6'. This holds true for all the buttons. I have this part of the program working well. there a way to have the addition of all these numbers appear in the fourth textbox WITHOUT having to use another button. In other words I want the fourth textbox to constantly update as I'm pushing buttons.

I am suppose to write a program using if statements and loops: Create an application that reads an integer number from the user and then displays in the List Box all prime numbers (for this project we are going to violate "positive" rule and make our prime numbers be negative as well) between user's number and zero 5 numbers in one row. The application also displays how many prime numbers there are between user's number and zero, and the total sum of all these prime numbers.

I've already wrote a simple program for connecting to a serial port that can send data to the microcontroller, do some basic arithmatic and transmit it back to my Form. This was just to see if I could set up the conection.I have a PIC Microcontroller giving an 8-bit number thats is taken from an external sensor device.What I want to do now is to present this data from the microcontroller in a textbox as a number either in real time (as the sensor output changes) or if not possible, on request (using a button).

I'm trying to show the line numbers with a stack trace when an exception is thown in my app.
This code is in the UnhandledException of ApplicationEvents:
e.Exception.StackTrace.ToString
It currently returns:btnOK_Click(Object sender, EventArgs e) at with no line number at the end.
I have set the project to create debugging info in Project Properties > Compile > Advanced compile options > Generate Debug Info = pdb-Only, and deployed the PDB file with the app, but still I don't get any line numbers.
I'm using VS2008 Standard, vb.net.

I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.

I'm taking VB at the college right now and we are studying Select Case Statements. What I need to do is type in a number in a text box and make it equal into a label so when i press my button the numbers I type in the text box appear in their letter forms. Here is my code so far:
lblNumber.Text = ""
Dim intA As Integer = CInt(txtBox.Text)
Select Case intA
[Code]....
I got it to work with the smaller numbers, I just don't know how I would make it so that if I type in a big number it would show all the numbers instead of just one.

For this assigment i need to show the numbers from 1 to 10 then 10 to 1 then the even numbers from 2 to 20 then the even numbers from 20 to 2 My problem is that it works fine till it gets to the even numbers. It won't exit the 2nd loop so it gets stucked in the 10-9-8-7... It all has to be in one button.

Write a program that asks a quiz show contestant to select one of the numbers 1,2, or 3 and then calls a Sub procedure that asks the question having that number and requests the answer. The Sub procedure should then call another Sub procedure to tell the contestant if the answer is correct. Use the following questions:1. Who was the only living artist to have his work displayed in the Grand Gallery of the Louvre?2. Who said, "Computers are useless. They can only give you answers."?3. By what name is Pablo Blasio better known?This is what I have so far (with errors):

Im trying to do a lab that will obtain 10 numbers from the user using an InputBox() function, store them internally in a one-dimensional array, and then compute the average of the numbers and sort them in reverse numerical order. The program should control that 10 numbers (no more, no less) are entered, and that the numbers are fully validated as integers.
If the user enters non-numeric data, then an appropriate error message should be shown, and that number should be allowed to be re-entered as a valid number. Then all the numbers should be shown as a list in a 'message box'. So far I can get everything but the message box to show the list of numbers entered.

Basically what I am making is a form with just one button and 2 text boxes. The purpose of it is that when I click the button 2 random PRIME numbers between 100-999 will show up in the boxes. With my code I have now, the numbers that show up in the boxes aren't always Prime.
My current Code is.......
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Randomize()
Dim p, q, i, j As Integer

I currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.
For example,
"This is a random text
file that I
have just made
up this second"
[Code].....
As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.
