View 1 RepliesI 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.

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?
View 4 RepliesThe 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 do not have access to the DLLs currently in production on a new project I am taking over.

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:

View 1 RepliesLet 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?

View 1 RepliesI'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?
