Creating Multi Level List Boxes In Access?

Oct 25, 2010

The first list box contains the project name. Based on whatever is selected in the Projects list box, the 2nd list box is generated with Custodian names associated with that project. I am having problems generating the 3rd list box. This holds the data sources associated with whatever is selected in the 2nd list box (Custodians)

Multi Forms And List Boxes?

Apr 12, 2011

Ok, Im having trouble passing a value from one form back to another using a listbox... The user clicks a button in the main form to bring up an instance of another form (form2.show). In that form, the user then then selects a number 1-5 and then presses done:

Code:
Private Sub frmPlayer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x As Integer
If lboNumber.Items.Count = 0 Then 'list box is empty
For x = 1 To 5

[Code]...

How do I pass that value back to the main form as a value when the user clicks done?

One Selection At A Time From Multi List Boxes?

Aug 8, 2011

ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.

I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..

Creating/Populating List Boxes At Runtime?

Oct 8, 2009

I am building a form that will eventually list a group of functions on the left. If you drag a function onto the form, it will create a listbox and a label at the loction you dropped it to. If you drag a function into a listbox, it will add that function as a listbox item. I have this working kind of. The problem is that once I create a new listbox, I am no longer able to add items to the previous ones. Here is my code:

Public Class Form1
Private MouseIsDown As Boolean = False

How To Create Multi-Level IF Statement

Apr 6, 2010

In my first application I need to create a multi-level "IF" statement and I am a little lost on how to proceed. The idea is to do figure out an estimate on costs based on the quantity of products being sold. I can do this in Excel, but the VB code escapes me.

So I'll show you in psuedo code what I want to do.
IF comboBoxA = 1 and comboBoxB = 1 then
value X
IF comboBoxA = 2 and comboBoxB = 1 then
value X
If comboBoxA > 3 and comboBoxB > 1 then
(comboxBoxA * costA) + (comboBoxB * costB) = Value X

I have another IF statement that will work off the calculations here. Haven't figured this one out yet, but I haven't gotten there yet in my form.
If Value X > Y Amount then
Offer product Z as a better idea

.net - Multi-level Inheritance With Implements On Properties?

Jun 18, 2010

Let's say I have 2 interfaces defined like so:

public interface ISkuItem
{
public string SKU { get; set; }
}

[Code]....

VB.NET explicitly requires you to add Implements IInterfaceName.PropertyName after each property that gets implemented whereas C# simply uses regions to indicate which properties and methods belong to the interface.

Interestingly in VB.NET, on the SKU property, I can specify either Implements ISkuItem.SKU or Implements ICartItem.SKU. Although the template built by VS defaults to ISkuItem, I can also specify ICartItem if I want. Oddly, because C# only uses regions to block out inherited properties, it seems that I can't explicitly specify the implementing interface of SKU in C# like I can in VB.NET.

My question is: Is there any importance behind being able to specify one interface or another to implement properites in VB.NET, and if so, is there a way to mimic this functionality in C#? Furthermore, what is the effect of specifying one interface over another when implementing properites?

C# - Multi-level Interface Inheritance With .NET And COM Interop

Jun 18, 2010

This question is a follow-up to my last question with a reference to COM Interop. Let's say I have the following 2 interfaces and implementing classes:

[Code]...

Interfaces are important in COM interop for exposing properties and methods to IntelliSense in the VB6 IDE (per this article). However, because ICartItem is inherited from ISkuItem, SKU is not explicitly defined in ICartItem and thus is not visible in IntelliSense in VB6 and even throws a compiler error when trying to write to objCartItem.SKU.

I've tried using Shadows and Overloads on the SKU property in ISkuItem, but then the compiler wants me to explicitly implement SKU for both ISkuItem and ICartItem within the CartItem class. I don't think that's what I want. Is there a way (in either VB.NET or C#) to explicitly declare the SKU property in ICartItem without having to declare SKU twice in the CartItem class?

.NET Custom UserControl With Structured/Multi-level Properties?

Aug 13, 2011

I can create a Custom UserControl with simple properties (Integer, String, etc) and have those properties show up in the Property Panel. I can also create a Custom UserControl with properties like Size, Rectangle, etc and the properties will show up as an expandable item in the Property Panel (click on the '+' and the Size expands to Width & Height).

Is it possible to create properties with my own custom structure? e.g. Property 'Message' expands to Text, ForeColor, BackColor, Blink etc. I have tried creating a property that references a simple class or structure with containing the properties representing my custom structure but in the Property Panel the property is greyed out and cannot be expanded or modified.

Selecting Values Of Combo Boxes And List Boxes In Web Browser?

May 22, 2012

I 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.

Send Data From Text Boxes / Combo Boxes To Access Database?

Jan 23, 2011

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.

What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.

The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.

I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

Placing Selected/unselected Items In Checked List Box Into List Boxes?

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)

Getting The List Of All Top Level Windows As Well As Thumbnail Images?

Feb 23, 2011

I'm developing a software for my community library, so I'm searching for a VisualBasic.Net code to achieve the following objectives...

1. Get a list of all top windows displayed on a computer...?

2. how would I retrieve the images of these windows...?

basically the scope of the project is to be able to monitor client activity on the library's client computer systems such as being able to tell how many windows are currently displayed on a client's computer and if possible retrieve thumbnail images of the windows...since the library is hooked up to the internet, the software intends to block use of file sharing sites, and pornography. It is easy to block unwanted sites with certain software, that is if you know what site to block, sadly the list of malicious sites is growing daily... so visual monitoring is required...

Module Level Variable - Array And Sort List

Mar 13, 2009

I just need to know where my code is jacked -up at, I get an error when I created the module level variable ( class statement must end with a matching end class) problem is that every time I add an end class the next procedure is wrong with the same error, so what can I do to resolve this and why is this error coming up. Ultimate goal of this program is to add the invoice totals to the next element in the array each time the user clicks calculate, which displays in a message when the user clicks the exit button, also this code will sort the invoice totals in the array.

Public Class frmInvoiceTotal
Dim SumInvoice(4) As Decimal 'Delareation of two module- level variables
Dim I As Integer = 0' the index I can use to work with this array
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

For example, in FireFox, under Startup and "When Firefox starts: you have a selection. This is what I want integrated into my program. Also, when the preferences have been selected, they can click an "apply" button in which their input can be recorded into a settings file. At this point I do not know where to go. Another important thing you should know is that all of the input is based on "Yes/No (Boolean).

Creating Serialized Picture Boxes

Dec 27, 2010

I'm building a simple game which involves many pictureboxes with which the player may collide. For instance, I'd have a hundred bricks spread throughout the level. In an old version of pacman I built in VB6 (and upgraded to .net), I implemented this like so: [Code]

As I understood, the brick(I) array exists thanks to the naming of the bricks, which ranges from _brick_0 to _brick_217 (as nowhere in the project a brick array is declared implicitly, at least not that I could find). I'd like to do the same in my current project, but even when I duplicate an existing brick it automatically renames it to "PictureBox123" instead of _ExistingName_NextID.

I saw a method of declaring a picturebox array and adding the bricks one by one, but since I have so many pictures this would best be avoided (especially due to the fact that not all pictures are bricks, so I cant just loop through every picture in the form). In short, my question is: How do I duplicate pictureboxes so that they'd be serialized in a way vb.net would interpret as a picturebox array? As you can see, i'm a really newbie to vb.net and wf in general, just started studying wf a couple days ago for my B.Sc and even that was accomplished with c#.
