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)
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?
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..
i have a database created in access showing in multi text-boxes in visual basic 2008 express edition. the database is showing music information and sales (tune name, artist, sales, and year issued) there are a few processes i want to do but can not work out the coding.1. display the top ten selling tunes in a particular year in order ( the year needs to be selected from a list box and displayed in a list box)
2.display the total sales in a particular year ( year selected from a list box)3. display the tune with the greatest sales in a particular year ( year selected from a list box)
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!
May i know how to change my below login code to support for multi access level login? So that i can differentiate between manager and normal employees login so that i can enable or disable certain features for different department? I have the below code that can serve as a basic login.

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 'rivate Functionlist As ListBox
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
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?
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?
I want to make multi level side strip with some data as shown in figure below:
The first column could be labels (names) read from an array or a variable and the second column could be a value to that label read from a variable or array. The value of the last column will be assinged to the label or in the first column. for example:
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.
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.
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.

I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.
In VB.Net 2010, is there any way to do multi-select in a drop-down/combobox, preferably with check boxes in the drop down? I've seen various discussions on the 'net about this but no such beast appears to exist within the tool.?
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)
Public Class frmCheckOut Dim i As Integer Dim cleaning As String = "Cleaning Inspection" Dim damage As String = "Damage Repaired"
How do one create System Level environmental variables manually. I just installed a GeoSupport Desktop Edition software and in the document it is mentioned that I need to create system-level environmental variables for PATH and GEOFILES manually
Add the location of the GDE executables to the system-level environmental variable PATH.Normally this means adding C:Program FilesGeosupport Desktop Editionin to the PATH.
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...
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 [Code] .....
I have a button ad a list box, the button when clicked lets the user select a directory on the HDD, and then the app is meant to list all the sub directory's of that folder int he list box. However I cant seem to get it to list just the sub directory names, not the full paths, and also to only scan by 1 folder deep (selected foldersub folder).
In my program, I have recently found it necessary to include a settings window. Here, there are two "Combo Boxes" which the user can click on and decide what to select. 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).
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#.
I thought i am doing fine with my project..The access level is fine.. when i login as "ADMIN". I can change the password.. But for other users, if i click save nothing happens but if i click it again it will save(In my savebutton event the txtbox is cleared if saved)
Here is the code for my login(this is the access level part)
If reader.Read Then Dim access As String = reader.Item("Position").ToString Select Case access Case "ADMINISTRATOR" Me.Hide()
[CODE]...
AND THIS THE change PASSWORD PART
