I'm just learning VB with the 2008 express edition.I'm trying to create a program that uses 3 list boxes.The first contains a list of products.After a search is preformed the second list box displays the products found.This is pretty simple, basic array stuff.My problem is moving items from the second list box into a third list box to purchase the product.I think I need to change the index numbers of the stuff I move into list box 3 because when I preform calculations with the stuff in list box 3, it seems to answer like its using the index numbers in list box1.So, how do you change the index numbers when you change list boxes?
View 3 RepliesI am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.
The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"
Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.
A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.
So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
what is the syntax to clear a combo box and also a list box?
View 3 RepliesThe project was to modify a previous payroll system project, which had a base class(employee) and 3 derived classes(salary, commision,and base + commission) under it by adding 2 more derived classes(piecework and hourly).Before I stated the modification, everything worked fine. When I would run the program the 3 types of employees would display in each output text box. The same thing is supposed to happen after I added the 2 additional types of employees, but now when I run the program, both output text boxes are completely blank. I'm not sure why I can't get anything to display in my 2 output boxes and all of the coding looks correct to me.

I had a small query relating to using an If statement.
Is there a short / easy way to populate 2 or more text boxes with different text if an if statement is true.
So.
If A = 1 then TextBox1 = "AA" and TextBox2 = "BB" etc
I've tried doing it with 'And' '&' but just keep getting a 'False' appear in my Textbox1 and nothing in the 2nd or 3rd.
This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)

I'm using Vb .net 2008
I could use some advice/examples to acheive the following:
I have 1 form, 4 text boxes, (textbox1 ,2, 3, 4)
Textbox1 and Text box 3 and single line text boxes.. Textbox2 is multiline.. (a description field which can be as long or short as the user desires..)
Textbox 4 is a large multi-line textbox that will contain the output of Textbox1,2,3.
I need to find out how to output the contents typed into Textbox1,2 and 3 into Textbox4 while maintaining formatting..
For example, contents of Textbox1 should always be the first text displayed in textbox4, immediately under that should be the contents of Textbox2, and under that, Textbox3
I want to ensure that the text is displayed in that order even if the user enters information into Textbox3 first.. and still displayed in the proper order if Textbox2 has 1 line of text or 20 lines of text.
How could I do this? How can I make the text from one box always be inserted before or After text from another specific textbox when its displayed in the destination Textbox.. (think of Textbox4 like a "preview window" of sorts.. which will later be outputted to an actual txt file.
I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4.

The Object Browser does not seem to help - am I reading it wrong?
View 14 RepliesI'm having trouble lining up data from a file with their respectable columns in a list box. I am using print zones to space out data evenly, but when i run the program the output is still messy. So I need lining up columns properly together. As of now, the first 2 list box items line up with each other perfectly, the data i am looping through to add to list box is not lining up correctly. I have changed my zones several times, but still no luck.

I am trying to create a WPF browser application that allows you to search and display recipes. The combo box presents choices, the Ingredients display in one list box and the "cooking" instructions appear in the other list box. What's happening is the first time you make a selection from the combobox nothing displays, and this could be happening because the first line of code under Selectionchanged clears the List Boxes however, it should be populating those list boxes with content, shouldn't it? Anyway, as you make other selections List boxes 1 & 2 get populated but they do not match what displays in the Combo box, i.e. if you select "Easy Taco Dip" any random recipe might appear in List Boxes 1 & 2.

I am surely a new self-learner programmer using VB 2010 Express edition and I have a problem on writing my first code. I have designed my form and I only want to add code as events. The IDE already adds the methods when I double-clicked the button which I want to add the code on.
This question may be good on the IDE forum, but I just thought to ask it here because there may be more experts here on VB language functions. I have added the MenuSctripItems such as File, Edit and so on. How do I write the code for New, Open, Save, etc under file menu? It may sound boring or even silly, but I am here to learn and your contribution is both for me, you and the MSDN.
I'm using the free version on Visual Basic 2008 (through school).The assignment is to populate a list box from user input text. The textbook only talks about populating a list of known items.ex animalListBox.Items.Add("dog") Which works just fine, however, we don't know what the user will input.
So, how should I be thinking about this?
If I'm trying to output to a listbox, what is the easiest way I can enter a string and then a variable on the same line? I'm trying to use listbox1.Items.Add(...). Obviously outputting a string is no problem and outputting a variable is no problem, but I want to add a string and then a variable after the string. For instance:
name = "Joe Smith"
listbox1.Items.Add("Name: ", name) [or something like this]
[Output] Name: Joe Smith
