Starting Calculations - Writing A Program That Has 6 Text Boxes
Nov 17, 2009
How do I start writing a program that has 6 text boxes. A person would enter a member number if they have one, number of movies rented at $1.80 a piece. A Text box should then display Total Rental Price, and if a member number was entered, a 10% discount is given (the total of the discount shows up in another text box) and after there discount is applied the Amount Due is displayed in yet another Text Box.
My boxes are named:
memberNumberBox
moviesRentedBox
rentalPriceBox = $1.80
totalPriceBox
discountBox
amountDueBox
This is all supposed to happed when the customer clicks on a calculation button named: Button1
This is what I have so far, but I don't even know if this is correct, as I am getting 1 error relating to a name not being declared. Please help and clue me in to where to start!
Public Class Bonanza
Private Sub memberNumberBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles memberNumberBox.TextChanged

I'm writing a program for my class, which pretty much is an energy cost calculator. It takes 4 inputs from 4 text boxes and multiplies them, and the result is the cost. Well, now I have to come up with a way to check for empty text boxes and display a prompt to enter a number. I've tried inserting multiple codes to display a prompt and to no avail nothing has worked, I also receive the error "when casting from a number, the value must be a number less than infinity" error.

how to go about populating some text boxes with results from calculations. To be more specific, I'm trying to do some trig to calculate various parts of a ci0rcle and will be populating any two of the text boxes then click on a button to get the missing values. I was thinking along the lines of a loop until all values have been calculated.

I'm working on my very first VB 2008 Express program, having a little bit of experience with VB 6.For my first VB 2008 program, I'm starting out simple. I have two text boxes, named Title and Director.You input text into each text box.I also have a button named GENERATE, which generates a text file named c.est.txt and stores the text box material.[cod]I know how to do this with VB 6, but not with VB 2008, and my research hasn't come up with an explanation of how to format this correctly.So how do I revise this code so that there is a line for each text box string, how do I get rid of the System.Windows.Forms.TextBox stuff and replace it with my own headers, and how do I double-space between lines?

I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.

I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?

I am trying to write a program that will compare two strings in different text boxes. Then it must add 1 to a third text box for every time a letter appears in both text boxes. So for example if textbox1 said ABCDF and textbox 2 said ABTR it should return the number 2 because A and B appear in both.
This is what I have so far
Public Class Form1 Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles string1.TextChanged
End Sub
Private Sub Compare_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Compare.Click
Dim string1 As String
Dim string2 As String
Dim Result As Integer
End Sub
Function stringcompare(ByVal string1 As String, ByVal string2 As String, ByVal string3 As String) As Integer
stringcompare(string1 As string, string2 As string) End Function End Class

I am making a program that loads, edits and saves 5000 rows x 100 columns of data. The data is stored in a datagridview. I use these commands to write the file:
dim z as integer
dim z1 as integer
fileopen(1,"c:drawermyfile.txt",openmode.output)
for z=0 to datagridview1.rows.count-1
[Code] .....
Every time I issue this command the whole program freezes until the computer is done writing the file. Is there some way I can get it to write this file without freezing up the program? Or, perhaps a better way to write this large data file?

I can whip up a program that deals with text boxes, buttons, checkboxes, etc. fairly easily. I know how to deal with arrays and stuff like that, and I am just barely able to open/write to files (I don't quite have it down, but almost). However, when it comes to drawing graphics. Right now all I'm looking to do is create a function that will draw a pixel or really tiny rectangle at my command to use as the building block of drawing images. I saw some example code here:
Of how to have it draw a rectangle upon opening a form, and I was able to do that. But I guess I'm not quite sure how to make a function like that be performed when I do something like press a button (or just anywhere in a segment of code).It's probably because I don't understand this line:
[code...]
I understand that it makes a non-public sub called Form1_Paint, but I'm not quite sure about the arguments passed and what "Handles Me.Paint" really means. I'm not sure how to make this (if I can make it) into a function that I can call anywhere (in the button1.click code, for example) to make it display a pixel.
how I could do that? Either that, or just explain what the piece of code above is actually saying?

I have a problem that I can not seem to get. I have a program that moves a picture to what ever location the user puts into the text boxes. It works as I wanted it to but my problem is when a user puts in anything but a number into the text box it gives an error, I want a message to pop up and let them know that a numbers needs to be entered not a text.

So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.

As part of an assignment, I need to add numbers which are displayed in a rich text box. The numbers are read from a text box. The user needs to be able to input the numbers as many times as possible. Since, the numbers all come from the same text box, I am unsure how to retain the old information and add the new information to it.Since I am not really able to make my point clear, I attach this picture: RTB.PNGAs you can see, I also have a problem with the heading repeating itself. Is there a way of forcing it to only appear the first time?Here is the

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.
