I want to draw string in multiple lines and and I want to know how many lines given string will take. I am using following method.
[Code]...
I have a large string variable that I'd like to split into multiple line for readability. What is the syntax to accomplish this?
EXAMPLE: Dim str As String = "asfrgasdfgadsfgadfgdfgasdfgdasfgdfgsdghsdghsh"
EXAMPLE: Dim str AS String = "asfrgasdfgadsfgadfgdfgasdfgd" _
"asfgdfgsdghsdghsh"
Something like that is what I'm trying to accomplish.
I have a *.txt file which contains instructions and data, with its own comments (preceded by ! ), blank lines, and each instruction begining on a new line, but occassionally using two lines. Each instruction consists of several feilds seperated by a TAB. Finally each instruction ends in a comma. Only a few different instructions are there (10 different ones) but there are many of each. Spanning a good 2500 lines. Comments and blank lines are obviously of no interest to me. I merely need to read the instructions and the data that follows it.
Now, I have successfully used 'System.IO.StreamReader.ReadLine' to go through it line by line, picking out lines begining with certain strings (first 3 characters of a known instruction). All good, I can 'lift' out the lines of interest and store them, for them to be split up later (seperating their fields into instruction, data, etc..) and then into an array.
The problem is, since some of the data fields in these instructions are so long, it spans two lines, before it ends with a comma. Using the above method, I end up with two array entries for a single instruction, since I have stored individual lines rather than a complete instruction. The only similar situation I can tihnk of to explain this, is to pick out sentences in text, and store each one in a string. Of course these end with a period (full stop) but span two or more lines.
I am hesitant to post an example, since its formatting is rather strange, but it is generated that way from 3rd party software, so I cannot change that for my software application.Perhaps there is no 'graceful' way of doing this, meaning I would have to find a way of 'adding' the second line of the instruction, to the string of the first line. Or perhaps reading each line character by character, literally storing every number/letter until I reach a comma.
1. i added a datagrid at runtime on a form. i want to bind a datasource to the datagrid in a button's click event handler, but the datagrid doesn't seem to be visible anywhere else outside the form load event where it is declared. how can i find the datagrid control?
2. and another beginner question.. how to i declare a string that spans multipe lines? i tried with the + operator like in c#, but it doesn't work.
I am a beginner and trying to learn. My problem is I am trying to break down a string for a part number. The string looks like" ABCD259A8755" . I need to separate it to sections like ABCD, 2, 5, 9, A, 8, 75, 5,
View 3 RepliesI am very new to VB, and am programming in VB 2008 express. Sorry if this thread is in the wrong spot I need to add two 40 digit numbers together and was thinking that the simplest way to do it would be to input them as a string and then convert the string to a single dimensional array where x(1) is the 1st digit in the number, and x(30) is the 30th digit, etc. I would do the same for the other number where y(1) is the 1st digit. I would then add the x(40) and y(40) (which are the last digits of the number) together and carry the remainder into the next addition (39th digit, 38, ...)

Ok, sorry to be so needy this week! Here is the situation. I have discovered how to do a linq query to get my data from my xml but when I return it as a string to a list box it is coming in as one large line. No breaks.

When trying to register a new user on the server, the server will post back messages such as "OK" and "usernameTaken". Upon comparing this returned string with another string (to perform an action based on the returned value), the compare isn't working.

backupX.startSocket("127.0.0.1", 8888)
Dim str1 As String = backupX.registerUser("user1", "testpass")
Dim str2 As String = "usernameTaken"

Looks to be like the socket code is working just fine.. each Function returns the corresponding Functions' Return value (registerUser -> SocketSendAndReceiveMSG -> sendAndReceiveMSG -> receiveMSG).

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.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

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.

View 2 Repliesi'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]

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.
In previous versions of VB, you could click on a label to gain the focus, and then type multiple of lines of text. In VB 2008, clicking on the control does not open up the control for editing. You can use the text property, but can only enter a continuous string of characters. How do you insert blank lines between paragraphs?
