Search Through Listbox Using Comma Separated Values In Textbox
Jan 7, 2010
I am writing a code to search through the entire listbox items and highlight them whenever user enters text in textbox. I am looping through textbox items which are entered using a 'comma' . But the code fails to add it to selected indices when user types multiple items using comma. It works fine for single items.[code]

I have 3 checkboxes and 1 textbox i use only these controls mentioned above ..I want ---- when i check checkbox1 and checkbox2 then it will display in textbox1 as 1,2 as it is as the same ascending order not 1,2, or 2,1,I use this type of coding in asp.net (VB) , i wanna use this coding for 45 checkboxes........
I've got a variable which contains a string like: dim test as string
test="bjcbhiabab,1,1,50,0,1,telepathie2,1,60,0"
Now I need to seperate all those values (each seperated by a comma) into new variables let's say value1 to value9 What's the most easy to use coding for this? I haven't got a clue which coding to use for this :S
I'm attempting to add comma delimited values to a combobox. The problem is I do not know if this is the best way to split the values into the combobox. Is there a more cleaner/efficient way to do this?:
Dim toread As String toread = ini.ReadValue("Schools", "Schools") Dim textdelimiter As String textdelimiter = "," Dim splitout = Split(toread, textdelimiter) Dim i As Integer For i = 0 To UBound(splitout) ComboBox1.Items.Add(splitout(i)) Next

I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.
I'm having a little trouble with this... I have a Session variable which contains a string of comma separated ID's which needs to be passed to a stored procedure but if it is more than 8000 characters, it needs to be split into more comma separated strings. For example;
When I look at a file on my hard disk, e.g. test.csv, when I look at the Properties of the file, it is officially known as, "Microsoft Office Excel Comma Separated Values File", and file types of .pdf are listed as "Adobe Acrobat Document", etc. etc. All of this information can be seen in Windows Explorer too when my folders are displayed by Details. How do you get at this "type of file" information with .NET?
I used a built in function to create comma separated string using List easily.(It is not split and join but new function) I'm not able to recollect or find it. If some one knows about it and uses it please post a link to that. Framework - .net 2.0
(It is not Join or split - I know about this, .net has new built in function to create CSV format)
Check Jacob G Answer below for what i was looking for let me know your thoughts on it compared to join ;)
And whoever gave me -ve rep need to keep some patience and not hurry
How could I have streamwriter write a , terminator for every space? For example if I have a line that reads "Hello World!" I would like streamwriter to write Hello , World
I'm trying to write two regex's - you'll need to tell me if they're even possible. Both are based on VB.net syntax.
Regex 1: The string I'm testing against - Size on disk: 25,754,900,936 bytes
It has a handful of leading spaces, but the text is ALWAYS the same. I'm trying to extract out just the number (25,754,900,936).
I've tried a handful of regex's, but I can't get everything on one line. The commas are messing me up and returning multiple matches (For example, d+W+ gives me four matches, one for each set of numbers separated by commas.)
The best I've done is [0-9/,]* but that gives me 25 empty matches and one match (On match 19) of the number. I need this to match on match 1.
What my problem is that, how can I load this .txt file to a datagrid and arrange it in a 3 columns. That .txt file is auto generated that's why i cannot do anything about the textfile.
i have code for loading a text file (comma separated) into my DGV:
If Not DataGridView1.LoadTextFile(TextBox1.Text, ErrorList) Then Dim sb As New System.Text.StringBuilder sb.AppendLine("Failed to load text file, see error messages below.")
[Code]....
I'm wondering...is it possible to run this code if the user was to drag and drop the text file onto the datagridview, rather than having to navigate via buttons etc...it'd make it a much nicer method!
This is my first 'serious' VB2008 project. Attempting to write a comma separated file. vis:
[Code]...
Is there a better method for outputing the data, rather than having to concatinate all the elements into a string and then writing it? In the 'good old VB6' days a Print statement followed by each value and a separator would do the trick. I can't seem to find the appropriate override for the WriteLine method.
Now it seems like a really simple question and I may just be being thick, but what I'm trying to achieve is basically print an array to screen in the following format: Item 1, Item 2, Item 3, Item 4 Although I say to screen, as that was the best way I could describe it, I'm actually writing it to the page inside some Javascript. The way I'm currently going about writing it out is as follows:
I'm using String.Join to attempt to turn an array list into a string that is comma separated, such as "1,2,3,4". I can't seem to get the syntax working.
Here's what I'm trying:
Dim aryTest As New ArrayList() aryTest.Add("1") aryTest.Add("2") aryTest.Add("3")
I'm working on something relatively simple I am trying to create a dynamic amount of comma separated strings.I have a variable (numberOfStrings) which is the number of different strings I need.I just want to loop thru the aryDrivers and assign then to the different strings.Dim aryHeats(numberOfStrings - 1) As ArrayList
Dim aryDrivers() As String aryDrivers = txtBatch.Text.Split(",") For i As Integer = 0 To aryDrivers.Length - 1 For j As Integer = 0 To aryHeats.Length - 1 aryHeats(j).Add(aryDrivers(i) & ",") Next
I am new to VB and need to make a program that does the following:Write a VB.Net program that allows users to enter a series of numbers(separated by a comma) in a text box called series. When the users clicks the command button called Average, the program extracts the number one by one from the series and calculates the average, and outputs the average onto a textbox called Result.I understand how to get it to do the average, but how can I make the program count the numbers that I input and then divided by the sum? Also, how would i get it started.
