VS 2010 How To Import Info From A DB To A Listbox While Crossreferencing Another List Box
Aug 3, 2011
So I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra.Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.
What I wanted to do was to create a new list box (lbOrderId). What I want is to be able to select a person from lbMatchingAccounts and have all their Orders populate in lbOrderId.
Currently I'm doing a resistance calculator. If i got 3 combo boxes which let user to choose the color code of a resistor, how to make the resistance of the resistor(resistance after count according to the color code choose by the user) go into a listbox after click "Enter" button? And also initialise the color code choose by user just now and the resistance after count.
For a class project I am supposed to search through the attached file, and write to a new file the years between 1789 and 2009 that are not present in the fifth field. What is my best bet for determining what years are not present?
[Code]...
Should I make an array of integer between 1789 and 2009, then search for every year in the file, then set a flag to false if not found; is there a simpler way to accomplish this using LINQ?
how can i import email from listbox to loaded url in web browser component?i have an url there www.mylink.com and when it loads it has a textbox and continue button. how to import email from listbox to that textbox and the application after inserting to click to continue button on loaded web url..
I am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties. The display is the song's Artist and Name, and the value is the song's file path (i.e 'C:UsersUSERMusicetc.').To write the file path to the .txt file, I believe I can use the following code:[code]
I am making a program, obviously, and I require some assistance. I found an explanation on how to read information from a Text file and have modified it for my needs. Here is my (modded) version:
Public Function GetInfo(ByVal playlistname As String) As String On Error Resume Next Dim PlaylistInfo As String
how to correlate info from a textbox based on a listbox item selection. For example the user will select an item from the listbox, enter say the length of a song in the textbox say 2:00 for song #1, select say song #2, enter the song time for that song say 3:00, click on song #1 again and have the same textbox display the length of that song and be able to do that until there are no more songs on the list.
When .Clear() is invoked, is the memory freed up that was allocated when all of the items were added? I need to load several lists of codes from a database depending on the import selected by the user. Each list of codes will be a List(Of String). My idea is that I will load only small strings into a List(Of String) along with a List(Of <class>) for the data I will be validating and manipulating. When I am done, I want all of the data from the Lists to be purged from memory. Will .Clear() take care of that or does the memory still remain allocated and have to be dumped by the OS once memory gets full? (And, incidentally, what causes the OS to decide which memory blocks to dump? FIFO concept?)
There are so many lists, I'm not sure if I just want them sitting in memory or not. Granted, the lists will just consist of a single string value for each code pulled from the database. So there won't be a ton of data, so maybe I could just load all the validation lists at the beginning of runtime and only worry about purging the data List since it will contain between 35-50 "fields" per record and there will be a couple thousand records each import that is run. I don't want my program to actually cause a hit in performance in the long run. I ultimately don't see a problem because I won't be running millions or even hundreds of thousands of records at once, but I just want to be sure.
So I am trying to code something in vb.net 2010 which will have a list box. For example:
1) Apple
2) Pizza
3) Juice
How would I display Line number 2 or any other to the user - I tried doing it with a label box like this Label1.Text = ListBox1.Text(2) - does not work.
I am trying to do is fill out a form with certain info, put the info into an array, and write it to a listbox using loops, arrays, and maybe a function if I need one. This is for VB2010 and here is what I have so far... I think there are ways to make it shorter but I cannot figure it out.... maybe just brain dead from all the coffee I have been drinking!
I have a ListBox containing a list of PDF files. The ListBox Click event displays the selected PDF file in a PDF control that serves as a type of preview for the user.
Private Sub lstPDFDocuments_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstPDFDocuments.Click
If IO.File.Exists(TempCurrentDocumentsBasePath & "" & lstPDFDocuments.Text) Then Me.pdfDocuments.LoadFile(TempCurrentDocumentsBasePath & "" & lstPDFDocuments.Text) Me.pdfDocuments.setShowToolbar(False)
[CODE]...
I want the user to select a PDF file with a click and be able to preview the document and when the user needs a larger view of a PDF file the user simply double click on the list box. When clicking on any of the ListBox items the selected PDF file is displayed in the "preview" pane. When selecting the mnuDocumentsView option from the context menu strip the new, larger, form reflecting the selected PDF file is displayed perfectly. But, when double clicking on an item in the ListBox the Click event is executed instead of the DoubleClick event. For some or another reason I cannot use both the Click and DoubleClick events on a ListBox. I've tried seperating the DoubleClick event from the mnuDocumentsView click event, MouseClick, MouseDoubleClick, but no luck.
I would like to create a program that will query all security permission to a given registry path. I attached the image so you have overview. I'm new to VB.Net 1/10 to rate my skill here. This will all the output I will put the output in a listbox or list view.
Ok, so I`ve been studying a bit of VB lately.. bought a few books and read lot`s of articles and seen hours of instructional videos, and I slightly start to get the hang of a few things.. :) I`ve recently started a fun little project, but I seem to lack a bit of knowledge to reach my goal. I`ll first try to describe my project:
I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
I'm trying to figure out a way to sort the entries of a listbox... but in a different way instead of the obvious one (sorted property). First of all, I need to explain how the items are populated at first:
Private Sub frmStudentScores_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ListBox1.Items.Clear() ListBox1.Items.Add("Joel Murach|97|71|83") ListBox1.Items.Add("Doug Lowe|99|93|97")
[code]....
The code works accept for the txtScoreTotal I need to Add the Numbers together but all it does is For Example Joel Murach|97|71|83 it will put 977183 Instead of actually adding them together.
this is a library management system, i dont know why it doesnt work, my code in the issue form is just the same as the return form but it doesn't work right here. it just populate the listbox with the info. from the database. my code is here,
Dim nnn As Integer Dim mmm As Boolean Dim xxx As Integer
I have 2 forms 1 that shows a name in a txtbox and Scores in a Listbox and the other form takes the selected score when you press the select button and you can change. Now I have it to where the old score is removed but when i replace it with the new score it doesnt appear in the same spot as the old score.[code]...
The problem is that it only adds to the text file it's suppose to read from, but instead of adding 4 strings into my listbox. Can someone figure out what's wrong with my code, and provide me the correct syntax for it. This is in a sub after click of a button in vb.2008.
I've made a listbox and imported multiple paths into it (writing the app in VB.NET 2.0).For example:
C:Path1file1.txt C:Path2file2.txt C:Path3file3.txt (varies depending on what the user selects)
I need to be able to grab each path seperately without having to get the user to select a particular item so i can do a batch of all the paths selected.
How do I get my info from a .txt from my website to load into my listbox?! Like if I were to do this... Try Dim client As New Net.WebClient client.Credentials = New Net.NetworkCredential("username", "password") ListBox1.Items.Add(client.DownloadString("ftp:public_html/listboxitems.txt")) Catch ex As Exception MsgBox("Error : " + ErrorToString(), MsgBoxStyle.Critical) End Try It just adds a straight line of my multi lines that are in the .txt file...
I have 3 textboxes that each gonna have something written in it.Say like.
Textbox1: Jonny textbox2: Tennis Textbox3: 1986
Now. I transfer this to a listbox.Now, when i press the saved item in listbox, I want textbox 1 , 2 and 3 to show up in 5 , 7 and 8.How to I get this to work?
I am currently setting up my own media player and so far there is only one thing that is making me very unhappy/frustrated. I have searched google so much and still couldn't find the solution. Here is my problem. I'm trying to import MP3s into a ListBox and have that as my playlist using this code:
For Each Song As String In Import.FileNames playlist.items.add(Song) Next
The only problem with this code is that it displays the song's full path in the list box. What I'm trying to do is just bring in the name of the MP3 without showing the path and still have the song play.
