I am having trouble figuring out how to parse a string with delimiters. I have a text box which the user inputs data or what ever. I need to figure out how to parse the string and display it in a listbox, each word in a single line. Here is what I have so far, my book doesnt explain parsing very well and I'm stuck
View 2 RepliesJust what the title says. I have a listbox with varied entries, all in one format:name, email, phone, age
When an entry is selected, and when a certain button is clicked, I require the entry to be removed from the listbox and the four categories from the entry must each go into their assigned textboxes.
I have to create a textbox which will list down one column of datas from textfile which is separate by delimiters.But as I have to filter alt.Row from the text file, what can i do?

I have the html of a page loaded into a string.
confirmUse('??????','Eat'
I want to extract the number that the ?'s represent however confirmUse is used in other parts of the page. The only constant is the 'Eat' which is unique to this specific number.
I usually use Mid and Instr to find what I need but when I try to back track it gives me an error because the index number is below 0.
I have a text file with preferences in it. I read the file and find text on a particular line like this:If InStr(sLine, "avidDirectory") Then This is my line in the text file: avidDirectory "S:Avid MediaFiles" "D:Avid MediaFiles" "Z:Avid MediaFiles"..What I need to do is read each string between the quoations marks and place each one in a text box.I have 5 texts boxes to use if there are 5 different directories above (only three in the example above)So I guess I need to capture the text between the quotation marks, create a new string from it, and place that string into a text box [code]
View 1 RepliesI'll start off by saying I am using Visual Studio 2008 Standard. I am creating a program that will open installed programs using short code. For instance, if a user types in 'npp' then Notepad++ opens. I have it working just fine to respond to the predefined commands, but I would like to expand it so that the user can define their own settings simply by typing the program directory and the custom short code they want: Example: If I am an end user and would like to say define a short code for Windows Media Player, I would simply type the following: (Assuming Excel or likewise is used to open the csv file).

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?
View 2 Repliesi've done some basic parsing with text files before.
Scenario is i have 4 textboxes String (which contains the string i'm wanting to parse) sub1, sub2, and sub3. so the string is ex. 500000-1-2
- is the char that is the seperator
so the aim here is to get
500000 into sub1
1 into sub2
2 into sub3
the real string i'm wanting to parse is much more complex, but i'm keeping it simple here for a jumping off point so i can figure the rest out.
I noticed no way to modify color at all with textbox, is this accurate? no way to enable html parsing, etc...richtextbox can without enabling html(better because scripting using html like font size, etc...can be un-desirable to allow all html...

I'm currently busy coding a hangman game in VB.NET.As a wordlist, I have a textfile containing 1520 words, each one seperated by a new line. The best I could think of to get a random word is with a Randomize() function. Then getting the word from the line # which was randomly generated.
[Code]...
Is there any better way for me to extract the word from that random line? If not, what would be the delimiter I should use for this and how do I quickly change the breaklines into that new delimiter without resorting to Office?
Also, how can I use the textfieldparser to get the file from resources? When I tried using my.resources.filename instead of "filepath", it gave me an ArgumentException due to "invalid characters in the path".
I just can't think of an easy way to do this. It seems easy, but I'm not just sure how to do this. I want the software to grab a random word inside the bracket "{}". The "|" is the delimiter. Here are some examples...
Input #1: {Hey|Hay|Hello} How {are|r} {you|u} doing?
Output Example #1: Hey How r you doing?
If I execute the code again, this would output...

I've been using VisualBasic 2008 Express Edition for a little while now, and I've gotten the hang of a few things like nesting and basics like that. I love learning everything I can about it, and so I'm working on a program that's got some things I'm not so familiar with involved. I'm not sure exactly what it is I'm looking for help with; as I'm sure some of you may know, there are many different ways to accomplish the same task--it's just that we don't always know the simplest solution, unfortunately. So anyhow, I'd like this program to do a couple of things... Firstly, to read in data from a text source and display it accordingly, and also to use that data in a list box and compile a new list from the original one.I've got a rather vague idea on how to do the first objective to put it nicely.I've read a little about delimiters and such, but the problem is that everywhere I look for tutorials or examples, I'm not really seeing exactly what it is I'm trying to do.Here's an example of the text I'm trying to parse/read/whatever it is:|Name of thing|some data|blah|blah blah|
In this example, I use the vertical bar character (I don't know what it's called; it's Shift + for me) to separate data in a pre-defined order. Let's say I wanted to use this for car information, I guess.[code]Like that, only many more times. What I can't figure out though, is A.) how to make VB read every line within the text file and B.) how to differentiate each of those sets of data so that I can read them into labels on the form. At this point, all I do know is that that vertical bar (this thing) is what's called the delimiter. Other than that, I'm left to pulling my hair out.
I am trying to add a text file with SemiColon Delimiters to DatagridView, i did few codings but getting a error as "

I am having some trouble including tab and space delimiters in my multiple delimiter code (see code below). It seems I can not just add the <vbtab> and <vbCrLf> codes into my delimiters list so I tried to replace them beforehand with a Clean String Function (also see code below) but it didn't seem to work. Ultimately, I would like to add any delimited text file to my datagridview.
The code below is working fine except for tabs and spaces (including next-to-each-other separators) I am using Visual Basics Express 2008.[code...]
I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

I have a csv file which I am populating to a datagridview. I am delimiting it using "," and "space". My csv file has "," at first instance and "space" in next two instances. I want to delimit the first instance using "," and the second instance using "space" and the third instance though has "space" I wanna ignore that space.

Now It only populates first text box with the first string in the array (For 0th index) and rest textboxes contains empty strings ,though texts array has values.
I'd like to learn how I can add a bunch of strings into the AutoCompleteCustomSource property of a TextBox. Actually that doesn't seem to be possible.. What I actually want to do is to make the textbox suggest and append 7000 strings. I can do suggest and append stuff already but AutoCompleteCustomSource can contain a limited number of strings, so I have to find another way to add my strings.
View 4 RepliesI'm making a random sentence generator that takes subjects, predicates, etc. from user input, stores them, and then randomly chooses one value from each category and prints it in a textbox. Or at least, that's how it's supposed to work. But I just can't seem to get the text to print in the textbox. Everything compiles fine, but when I click generate, Windows gives an error.
