Parsing Listbox Entries Into Textboxes With Comma Delimiters
Oct 9, 2011
Just 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.
So in my form i have the user input a bunch of data that gets written to a listbox. Like so Pre_Study_Listbox.Items.Add("Team Members are: "). I then save the listbox to a .txt file and they can later load the .txt file back to the listbox. All this works great. But now i need to reverse the order of textbox to listbox and put the information back into the textbox fields from the listbox. So. The parsing character is ":" I need to read each line of the listbox and at the ":" take the rest in put it to the text box. I am not familiar with the parsing command
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
I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables Dim strName As String Dim strArtist As String Dim strPrice As String
What is the best method to parse through a Comma Delimited .dat file? I am using VS2002 and VB. My code will be looking for certain placeholders within the files and pulling the value from that element to populate a table in SQL2000.Here is a sample of one row that is in the database so far:17768 01 1770 003 2009-11-01 00:00:00 5065.14 NULL NULLEach spaced section is taken from a part of the .dat file, but being manually keyed in for now. My job is to automate the reading of the file, and writing it to the SQL database.Here is a sample of the flat file I am trying to parse:
So, for my computing project I have to import csv files (got that bit working, got it opening up and displaying in a text box) and search through it to find criteria that I want.
Anyways, I am having trouble splitting/parsing the csv file so that it will display with no comma's (in a kind of tabbed form) e.g. at the moment it displays as
I need to count the number of duplicate entries, and provide a summary (count) for each product code. This makes it easier when the order needs to be placed, and the user don't have to count each value manually.
I have tried looping through all 50 boxes to no avail. This seemed easy, but, clearly I am to thick to think of a solution.
I've read through all the search results for this and haven't quite got it yet. I often get given Excel spreadsheets of file names and have to check through them for duplicate names.I am making an app to do this for me. I've extracted the data from Excel I'm just having issues with checking for the duplicate. I've tried 2 different ways I found online and neither are working for me,
I am trying to delete multiple selected entries from a listbox. When I run the code I have now, instead of deleting all of the items that are highlighted, it deleted all the items in the listbox.[code]
I've imported data from a text file using Streamreader and populated a listbox with this in 3 columns. I now need to a) get a total value from the 'Hours Worked' column (sum) and b) put in a calculation to populate an extra column for each entry (Gross Pay) where values are not imported but entered as a result of a calculation.
My current code is as follows: Private Sub btnRefresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRefresh.Click 'Program Objective: Display payroll report for National Success Coaches which could be updated unknowingly at any time. Dim name As String [Code] .....
I just starting coding in VB.net about two weeks ago so I'm still a begging and I learn best by seeing working code and then adapting it to my situation. That being said, I need help displaying table entries in a listbox. I've successfully created a database in my test application, added it to my Data Sources and used a drag / drop method to add Datagrid View & Details (labels & textboxes) to my application for testing purposes. Now I want to try and display table entries in a listbox.
Also is there any benefit or down side to creating a database in MS Access, create the relationships & tables, then attaching that database to my application or is it better to create the database in the application like I did in the example above by using the Add New - Service-Based Database option?
My program is half a formulator, and half ordering system. Where I get stuck is the ordering system part. In one screen I have 5 check boxes that you can check for which products you want to order. The products you checked then get sent to another screen and put into a list box with a quantity variable that starts at 1 attached to it. Now, if you check the same product again, another time through the program, as of now, quantity accumulates to 2, which is good, that's what I want. My problem is I want quantity to keep accumulating, right now it accumulates to 2, then on a third pass through the program,it duplicates the entry, so now in the list box has the original product and quantity of 2, and another entry that has the product with quantity of 2. 't quite understand how they work. Here's the code:
Option Explicit On Option Strict On Public Class OrderRequest
I have a program with two forms, one that handles the applications controls, and the other with the functions that open a file (csv), open a database, and query the database. The controls on the first form are a list box, three labels (to display parsed csv information), and three buttons (clear database, load database from csv, and load listbox).
The clear database and load database buttons (events) seem to function correctly.On the other hand, the load list box event doesn't function 100% the way I'd want. [And, I can't test the selected index event yet]
The code for the load list box event is:
Code: Dim db As New DBUpdt 'second form b.openConnection("weather.mdb") 'open database connection db.query("SELECT * FROM stations") 'query database Do While db.moreRecords
You see, in my new VB application, I have a form with a TextBox and a ListBox, and I need to make it so that, whenever some text is written in the TextBox, a SELECT operation must be performed in a table belonging to an SQL database, in order to return the elements of a particular column that are LIKE the text I just wrote in my TextBox. The results of this SELECT operation must then be written inside the ListBox.In other words, whenever I have some text inside my TextBox1, I have to do:
SELECT Description FROM Elements WHERE Description LIKE TextBox1.Text (this must be done whenever the text changes)And the results of this operation must be displayed in the ListBox on the side.
I have 7 textbox entries and I would like to add them to a listbox and when I close my application it would save them, I have the code for the 7 texboxes and everything like that has been done, but I just dont know how to add multiple textboxs to a listbox then save the list box so when I close the application and reopen it, itll still be there. I know I need a button to add the list to the listbox, but how do I save them, so theyll still be there?
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]
How should I code to display the name in the listbox following this format: Lastname comma space firstname (foe example: Depp, Jonny), when the user input a fullname from a textbox( Jonny Depp)?

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?
I'm trying to parse csv file with VB.NET.csv files contains value like 0,"1,2,3",4 which splits in 5 instead of 3. There are many examples with other languages in Stockoverflow but I can't implement it in VB.NET.Here is my code so far but it doesn't work...
Dim t As String() = Regex.Split(str(i), ",(?=([^""]*""[^""]*"")*[^""]*$)")
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;
iam stuck at the following: Have to create 2 textboxes with a listbox: Textbox1 you can put in a amount of money..Textbox2 enter a percentage..Now comes the hard part (for me):The listbox must show the amount you have gained by the percentage so like this: You put in 500 euro's, enter percentage 10. [code] ye there's another part, if the first amount is shown, the percentage calculated for the next amount must be calculated with the first amount.
I am currently working on a program, which needs to take data which is within a listbox and out put to three textboxes.I currently have a 2d array which populates the listbox with data.The array has 4 columns.when double clicking on a chosen entry within the list box i would like 3 textboxes to become populated with the last 3 columns data.i know i must use 'Mouse Double Click' within the listbox to activate this, but having a problem with how i could only have the columns 2,3 and 4.i have read so many different search results on this matter i now have the problem they are all marked as read and still cant get my head around it.
