ComboBoxes - How To Get Info From Array And Display In Textbox
Apr 25, 2010
I am trying to do a form it has 2 comboboxes and I have the arrays set up one of the combboxes is for pizza size and it has 4 selections and the other combobox is for crust style it has 2 selections. The user has to pick on of each and it pills the price from the array and then displays the price in a text box. I for the life of me can't figure out how to get it to pull the info from the array and then display it in the text box, it either displays nothing in the text box or a 0 or 1.
I am creating a program that make a person select different options and in other boxes it will populate the choice the person makes. Example is the program is fora car wash and if you choose standard or deluxe it will show in the other boxes what comes with that package.I got the program to work except when going to select a different option it still keeps the old info and displays the new info as well. I tried like at the bottom of the procedure Exteriorlist.Items.clear() and it would clear and never display the info. I am still working on the project I am trying to get the print option working properly I am just needing help in figuring out how to clear the info when I select a different package.
Public Class CarWash7 Const EXTERIOR1_String As String = "Hand Wash" Const EXTERIOR2_String As String = "Hand Wax"
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 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!
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.
I have completed all the code for a loan calculator, but am unsuccessful in displaying decimal variables in string as "currency". I have added the .toString("c2") statement and only get one array to display in currency, then the second array does not round properly. Is there a convert function that will work? Here's my code:
Public Class frmLoanCalc 'Ken Schoening 'Loan Calculator
I have 3 databases: Subject, Class, and Students. In the Subject database, I have SubjectID and SubjectName and the PK is SubjectID. I have the releationship bound to the Students table where I only have the SubjectID in there. Next in the Class database I have ClassID and ClassName. ClassID is the PK and it's relationship is bound to the Students database where I only have the ClassID in there. Here is what I am having troubles with.I have comboboxes set up on a form to where the user can select which class and which subject the student is good at. What I want to do is to be able to insert those values into the Students table so that the values will make the correct Subject and Class name appear on the students record. I also want to be able to modify said Subject and Class ID, which when you click on the button, brings up another form to edit Student info, such as name, address, phone number, etc.
I am not sure what I am doing wrong. I take the comboboxes and display them on the form. For the datasource I use the Class for one and Subject for the other. The display member is Subject name or Class name and the value member is either class ID or Subject ID. When I run the project though, the class name and subject stay the same for all the students. I have sample data in my tables that is different for each student, but it does not work.
I've been working on a VB project where I use a 1st drop down list to select a movie category and then in the 2nd drop menu, movies from that category will be displayed. The movies are stored in a 2-dimensional array by category. I've been able to edit my array but I'm having problems with my .AddRange() function. What would I have to put in those parentheses for the list (for each category) to appear in my 2nd combobox when the category is selected?
I'm working on a college VB project using an 2D array with 2 combo boxes. One combo box selects a size and the other selects a style. I have everything working correctly with calculations except I need each combo box to pop up a message box if the user doesn't make a selection in a combo box. It will pop up for one combo box, but not the other. My question is how do I get the program to pop up a message box for each combo box independently? Should I use Try/Catch or would another method work better? (I'm using VB Studio 2010)
Private Sub CalculateToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CalculateToolStripMenuItem.Click 'Retrieve price of selection.
I use VB 2010 Express My problem is:I have two comboboxes one button and one textbox.So what I am trying to do is.Add company names Like EA Games and lets say product name is Crysis.and I want it to show the barcode number of the product n P.I.D?
i try to make an array of controls and by clicking buttons add new textboxes or comboboxes here is my code
Public Class Form1 Dim CArray() As Control Dim lngArrayNum As Long = 0
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Add_Control()End Sub Private Sub Add_Control(Optional ByVal intType As Integer = 0)
this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):
I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

I am upgrading from VB6, using MSXML.XMLHTTP object. I believe I have gotten the .Net Webclient to send the form fields, and a response comes back from the site, but everything in frames. The VB6 code automatically had all of that data, how can I get that in .Net I know this is a Newbie question if you can point me to documentation,
I am brand new to VB2008 from VB6.I am trying to connect to my remote mySQL db and simply display a record into a label.Here's what I have on Form Load.[code]
I'm learning about the cultureinfo and doing ok but there is one thing I can't work out.I'd like to know how to find out the display settings of the date for the user pc.For example, I have an American bought laptop using the us culture so the date will be MM/dd/YY but I have changed the date setting to read dd/MM7YY. So that means I haven't actually changed the inbuilt cultureinfo, I've just "altered" a setting and it's that setting I want to access. When my project starts I have a label that I want to read as dd/MM/YY.With another pc it might be different - the culture might be uk but the date setting might be changed MM/dd/YY so I want the label to read MM/dd/YY etc etc etc.If the cultureinfo hasn't been changed then I want the label to read whatever the date is set to etc.
I need to display info about each of the 50 states when selected in my program. I have one combobox with all the states as items inside, one button that you click to get the info and one listview for displaying the info. Here is my code so far:
Imports System.Text.RegularExpressions Public Class Form1 Private Function getinfo(ByVal state As String)
im trying to edit a code so that i can display user info in a listview rather than a listbox because listview has some options i want to use , i have 2 errors one in Public Sub removeClient and one in Private Sub AddClientToListview i would be very greatful if some could give a helping hand to resolve these errors
vb.net Imports System.Net.Sockets Public Class form1
Code: Private Sub weeklyTextBox_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'disables and enables correct buttons for initial start
<Assembly: AssemblyCopyright("Copyright 2012, Company Name.")>
tried this:
<Assembly: AssemblyCopyright("Copyright" + DateTime.Now.Year.ToString() + ", Company Name.")>
I get invalid constant error.
I don't want to use registry key entries, what is the optimum way of doing this? (so that when a user right clicks on EXE & looks for assembly information can see current year).
I have been tasked by my boss to create an application that takes information from an excel database holding sales figures, margins, budgets etc calculates all the figures and exports the totalled values to a table and graph also in excel. Although this is fairly easy, there is some complications I am dealing with. In the database there are many territories, and each employee has 1 or more territories.I'm not sure what I have done wrong, however the totals are not adding up properly. My code is:
'Defines Excel Objects Dim objExcel As New Excel.Application Dim objWorkbook As Excel.Workbook Dim objSheet As Excel.Worksheet
I'm trying to get this form to display in the listbox the address from the info from the textboxes and it works except one problem, it displays all on one line. Its seems as if it accepts the ","'s and " " for the address but ignores the vbCrLf line separator. What am I doing wrong: Here is the code for the class:
After display list of data in combo box, next I would like to choose the data from the combo box and display all the information from the chosen data to texboxes , the data from combo box was link from my database (ms access).
I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to: read/write/delete from it read possibly up to a 20mb file and sorting it without a lot of lag be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.
