What Else Can Store Numerical Data In Multiple Lines
Mar 4, 2010
For the code below I get an error for the 1 to 5 part. It says end of statement expected. Is the way i've set out the syntax wrong, e.g the 1 to 5? [code] Also other than storing text to a rich text box what else can store numerical data in multiple lines?
I'm a complete novice with VB and any coding in general, but as life will have it, I have to create a program for my Final Year Project at university.In short, the idea is to open a file that has many lines of numerical data, then select the required lines, do some calculations on them and write it into a new file, but the new file must have its own format and the calculations must go into the correct lines.
Im struggling really with how to get it to read the file and then write the new one. Currently I have it so the user can open the file and it will display the data into a text box. I want to then be able to click another button that will convert that data into a new type, and in turn display that in another text box. Then have a save button to save the newly created data. This is what I have so far...(it's not much.I havent really got much of a clue what I am doing lol)
I'm having a bit of an issue with this program I have been working on for my class. It's a future values calculator, that takes a single data type, decimal data type and a integer data type does the formula and then spits back out the Future value. What i'm having difficulty with is converting the string over.
Public Class Form1 'Define the Module level variables Dim FutureValueInteger As Integer
I'm creating a calculator in visual basic 2008, and with this calculator I want to implement a feature that can store numerical values in a variable for instance x. Similar to the feature used in most graphing calculator that have the button showing: "STO->". I was thinking on using the My.Settings. But I'm having trouble on it.
I have a file which is opened and the bytes are loaded into a class.The file needs to be split into chunks, and there is a header which gives the locations and sizes of the chunks.Should I (upon opening the file) split the file into chunk sand store each chunk in an array of variables And then when I want to access the data in the chunks I just use the array.
or store all the chunks in one variable together and then when I need access to the chunks get the location and size of them and use that to find chunks each time I need to modify them.
I'm new to Visual basic (which will be obvious from my question) and am writing program that does various calculations, then displays the results in a list box. the results, however, are all concatenated, end don't each appear on a new line. I tried adding a carriage return/line feed at the end buit the compiler rejected it.
I can't find any examples of creating a list box, and adding multiple entries (one for each time a loop is performed), nor of how to use columns to make the resulting display cosmetically pleasing.
I have a application that use threadpool, and each thread stores data in the same textfile. I now want to have each thread store the data in the same array instead and use a timer to store all current data in the array into the text file after every couple of minutes.
So what I want to do is:
1. All threads store data in one array that they all have access to
2. After every couple of minutes the data in the array is stored into the text file.
I know number 2 can be done with a timer, but is the first one possible? If so how do I accomplish this task?
i need to take data input from a textbox such as this
13:41 A spider loses 20 hitpoints due to your attack. 13:41 You gained 18 experience points. 13:41 Loot of a spider: 2 gold coins, meat 13:41 A wolf loses 25 hitpoints due to your attack. 13:41 You gained 27 experience points.
I am designing a test launch tool that I want the user to be able to select a product type from a list and then choose a station type from another list. Depending on what they choose will determine what is run (what is passed out).
The data will look like the following : Product Station Test to load Config file to use 10-9890-1 mfgtest1 Progamming.xml config5.conf 10-9890-1 mfgtest2 Configuration.xml config92.conf
I am checking for empty string values, but how do i see for the Quantity text box if the user chose only numerical values after the empty string. For example...
how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
this list has tried to mix numerical variable, such as 1, 2,3 within an xpath expression. [code] For some reason, item_ number_ first and item_number_last appear to have no value in the above code snippet, when they do have values they get printed as in the [code]Could anyone please give me some hints on what to modify here to make the numerical data be able to mix within my xpath?
I have the age old scenario where I have parent child related data. The child data contains many records with a cost field that goes into making the total cost on the parent record.
Is it good/bad practice to store the totals in the lines and also the summed total in the header?
The system will require that the child records be manipulated and therefore, the summed total will change. I also have a requirement where the summed total will need to be calculated and displayed on several forms and reports. I am able to code the system either way just wanted peoples opinion.
I have managed to format a text box to be formatted to two decimal places, and to only accept numbers.Only problem is i need to allow the backspace so that if someone types something wrong, they can backspace and type the correct number
Private Sub txtCAmount_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtCAmount.KeyPress 'Allow only numberical input plus decimal. Dim allowedChars As String = "0123456789."
I am trying to figure out a way of combining the below Dim statements into one line and maybe also combining Return dblResult into there. currently it is three lines and I have been told that it is possible but kind of lost of how to do it
So I built myself a simple program to work out the kinks of drawing in my programs. I have a button that I press that when the textbox.text reads 1 it then draws a line of a specific height, color and position, the problem is when I click that button again it will crash informing me that... "Specified Visual is already a child of another Visual or the root of a CompositionTarget." [code..]
I know where the problem lies, its with the Canvas1.children.add(line), cause its telling me the line variable is already been used or in use on the canvas, I'm just unsure of how to turn that into a solution that will allow me to click the button a hundred times or more without being forced to MANUALLY make a hundred or more individual variables to store the line.
So i am working on something for school. And we have to make a program that has 2 buttons, 2 text boxes used for input and a label used for output. One button is New Customer wich displays this in the output label (named totalLabel)
Public Class Form1 Private Sub newButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles newButton.Click
I'm creating a button on my project that when clicked it will enter the information in the comment "" area and store it into the clipboard to be pasted.
My issue is whenever I try to put the multiple lines in the comment field I get a syntax issue.[code]....
Is there any SHORCUT for multi lines commenting in vb.net .. Altouhgh i know there is an option in toolbar for multilines comments but i want to know a keyboard shorcut for it...
I have tried multiple variations of the following code, but I still get the same result. I am trying to have the last line "Issue Description: ...." to appear on a new line. I have tried vbCrLf, vbCr, and & Environment.NewLine & _ None of which work.
Just a note: The other emails are properly formatted. Also, if I add put 2 vbCr (s) at the end of the 'Issue Title' line then it looks normal.This one in particular seems to be a thorn in my side.
The result:
The code:
Dim mail As New MailMessage() Dim strbody As String strbody = Nothing
i've got my basic AutoTyper ready (well and one with autoupdating etc in it) but it's only a singular line. [Code] What I want to do it to type multiple lines, I know I'll have to enable multiline on the TextBox. I want it to type one line per time interval using 1 timer. I don't know how but I know it would have to count the lines but from then on I'm stuck. I will need to make it type line 1, then on the next loop line 2 and go on until it's reached the amount of lines from the count then repeat from line 1. [Code]
