View 3 RepliesI've been racking my brain lately to try and come up with an algorithm to set a frequency rate at which an object may appear.
This best way I can think to describe a "for instance" is gonna sound nerdy but here goes.
Say I have a subclass that is just one of many on a Large class, kinda like spades in a deck of cards. However I dont specifically want 13 spades in my deck, I want to randomly generate this deck with a random chance of spade appearances. but beyond that, i want to give each sub-subclass, like a jack of spades, a "Frequency number", that upon generation of this main class (or deck in this example) will use random in combination with this "frequency rating" (0-100) to place the sub-sub class and even the sub classes in place.So as for my example, a 2 of spades might have a high freq like 90 and thus showed up 15 times in my deck, while the jack, with a rate of say 20, only showed up once or twice in my deck.
i want to read a character 1 by 1 from a string and a .txt, i know all about stream reader so for the .txt would it be somthing like:textbox1.text = tr.readCharacter.i would prefer to be able to read from a textbox or String array though.

I have built a DataTable from my database. Then I am looping through the rows and trying to access a string, however the value is being returned as each character in the string.

If theseRows.Item("Last_Name") = userLast And theseRows.Item("First_Name") = userFirst Then

The Trap_Code values are two or three letter strings, the returned value is each letter once at a time. The loop seems to cycle through the individual characters of the string as an array rather than display the entire value, which is what I was hoping for.
The following code:
If checkboxList.Items(i).Selected Then
.Fields("DESC1").Value += checkboxList.Items(i).Text + ", "
End If
should produce output such as "A, B, C,(space)", which will then be bound to a dynamically created GridView. I would like to remove the last two-char string, that is ",(space)". How can I do this?

what is the best way to remove FileFinder1 from this string:
"C:Program FilesFileFinder1"
Basically the first letter of a string must be a certain letter. At the moment the only way I know how to do it is as follows:
If sConsignmentNo(0) = "J" Or sConsignmentNo(0) = "C" Or sConsignmentNo(0) = "U" Or sConsignmentNo(0) = "N" Or sConsignmentNo(0) = "H" Or sConsignmentNo(0) = "S" Or sConsignmentNo(0) = "V" Then
Basically listening the same thing out over and over. Is there a way I can say, If sConsignmentNo(0) = ListOfValidEntries i.e J,C,U,N etc?
Using Visual Basic 2008 and cant use regex!
I have written my own function, which in C would be declared like this, using standard Win32 calling conventions:int Thing( char * command, char * buffer, int * BufSize);I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere).UPDATE:This code is now a working solution, as shown here:
Imports Microsoft.VisualBasic
Imports System.Runtime.InteropServices
Imports System
Imports System.Text

Updates: I got the code to build by following the help received here, and then I had forgot the As Return Type (which got me a MarshalDirectiveException PInvokeRestriction). Then I had an assertion failure inside my DLL, which lead to an SEHException. Once fixed, this works BEAUTIFULLY. There are newsgroups where people are saying this can not be done, that VB only loads managed dll assemblies (which I guess is the normal thing most VB users are used to).
I have a string like this.
Dim str As String = "code"
I need to break this string down to an array of characters like this,

How can I do this?
I have a string that goes like "abcdefg..."
I would like to find the index where the letter d is at, so I can get the number 3.
I managed to do it by looping through each letter in the string, but that doesn't sound very convenient.

I am developping an app which talks across a network and will eventually be used to read in a text file (on the client) and transfer it to the server. Currently, the server and client succesfully connect to each other using the Tcplistener/Tcpclient classes. I am now trying to send some data across the network using the networkstream class, which I have implemented.Currently for testing purposes i am sending a char array which contains the characters "hello" which succesfully sends and outputs to console on the server. Although, "hello" is followed by a long list of whitespaces. I have tried converting this to a string array on the server and/or client and using the string.Trim() function (amongst trying many other things over the past couple of hours) although the output remains the same.
