I am trying to make a program which outputs an Invoice Number, which consists of the first 3 letters of a person's first name and the last 3 digits of their zip code. The user enter their first and last name, then enters their city, state, and zip such as:
Name: Billy Jones
City, State, Zip: Chicago, Illinois 42349
Therefore, the invoice would look like:
Invoice: Bil349
I can get the first 3 letters of the first name fine using the substring function, but I have been stumped on how to get past all of the text to get the last 3 digits of the zip code entered.

I get this error when I try to connect to my database. I used the same string provided in the database explorer "Connection String"
I do not have a password on the database.
This is a local database if that makes a difference

Well I've been looking around on Google and experimenting with code but nothing seems to work. The only things I can find are hundreds and hundreds of lines long - there surely must be an easier way?

The string itself contains things like "random" & random.next(1,3) & "random2" etc. The string registers all of this as a string and doesn't actually calculate random numbers.Is there any way to fix this?

I have buttons generated through code (dynamically). I have to associate an event (the same) to them. I use AddHandler button.click, AddressOf mysub.The issue is that mysub gets a string (mysub(string)), but AddressOf doesn't accept a parameter inside the routine. How can I do this? Using also an alternative to AddressOf.
EDIT:
Public Class Form1
...
Private Sub mysub(ByVal sender As Object, ByVal e As System.EventArgs, ByVal str As String)[code]......

Using VB.NET, Is there a way to do this RegEx call in 1 step... instead of 2-3? I'm trying to find the word "bingo", or whatever is between the START and END words, but then also inside the inner FISH and CAKES words. My final results should be just "bingo".
Dim s1 As String = "START (random string) FISH bingo CAKES (random string) END"

I do not have access to the DLLs currently in production on a new project I am taking over. The source code is accessable but I want a copy of the original DLLs that were compiled and implemented in production via GAC. When I explore 'C:WINDOWSassembly' the DLLs are properly registered there as expected. I understand the GAC store the DLLs somewhere. where so I can get copies of them. The OS of the machine is Windows 2008 Enterprise.

I have a problem with MDI forms and their location. I have a container form within which I open several child forms. Also note that in the container form I have a ToolStrip at the top and it is also docked to the top. In each of the child forms I have set the following properties. I have set them at design time as well but it wasn't working for some reason so I put them in the form_load event as well.[code]...

I want to learn more about API codes, but I don't know how to get started. The thing I want to accomplish today is:basically I want to be able to locate a certain text box anywhere on my computer, and then I want to be able to write something to it. For example here on Firefox, you see the navigation toolbar. I want my program to find the name for that window, and then to type for example ("www.vbforums.net") automatically.

1.) I have extended the Tree View Control into a user Control with the following code to include a key value and a value, like it was in VB 6 and .Net 1.0, and it allows me to read the key of a created (extended) Tree Node, but once I insert the node into the extended tree view control, it will not let me referece the key property of the node in the context of a nodes.find.

I've made a function in C# to create a random string, but I wanted to convert it to VB.NET, unfortunately my knowledge of Visual Basic is much less than my knowledge of C#.
Here is my VB.NET function:
CODE:
As you will see, its not much different from my C# version, except that since VB can take an optional parameter, I allow the user to select what characters to use in the string, or just use the default ones.
Here's the C# version of my function:
CODE:
Again, there's not much different, but the part I'm really struggling on is the conversion between what is the 12th line of VB code, and the 13th line of C# code. I didn't really know how to convert it to VB.NET (as I said, my knowledge of it is very limited), so I used an online converter. The result of the online converter runs with no errors, however when I try to call the function, no string appears.
In short, this C# code works fine:
CODE:
However, this VB.NET code doesn't work:
CODE:
How could I fix my VB.NET code?

Let me say that I have 'f' as a file/folder path.
Dim f As String = C:UsersTom BluewaterMusic
Dim d As String = Path.GetDirectoryName(f)
Is it possible to locate f within its parent directory (d) as shown in the picture below? I know that you can open its parent directory like the following.
Process.Start("explorer.exe", Path.GetDirectoryName(f))
And that's not exactly what I want. In this case, the Music folder won't be selected. I could search this place for a clue. But there was no hit. It seems that the search function doesn't always work here.

I'm very new to VB, so I was in the very first tutorial, it has me play a sound file. So I put that in, ran it, and it came back with an error saying "system cannot find this file." I guess I'm not terribly surprised, since the file they gave has no C: or anything like that. What I want to do now is play my very own sound file, but I don't want to go through the whole C:Documents and Settings... thing, so is there a way I can put my own sound file in the project directory and say something like %ProjectDir%/sounds/mysound.wav?

When I attempt to add a Service-based Database in VS2010, when starting a new project in VS2010, I receive the following error immediately after clicking "Add" when the Service-based Database is selected.A network-related or instance-specific error occured while establishing a connection to SQL Server. The server was not found or is not accesible. Verify that the instance name is correct and that SQL Server name is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified.)I've googled this problem and found this topic (url...), which wasn't able to help me. I'm still finding additional topics to troubleshoot with as well..

I'm writing a VB.Net WinForms application that has multiple data girds on any given form. On one such form, the data grids are loaded into split containers which in turn are located on a tab control. The load method for each data grid is threaded so that an animated "Loading" form can be shown. I would like to position the new loading form (which is smaller than the grid) on top of, and preferably in the center of, the grid that is loading. Whats the easiest way to find the grids location within the main form so that I can adjust the loading forms location?
