VS 2008 Converting An Array Into A String?
Feb 19, 2010[code]There are 5 matches every time. I have another function that needs to use each match but as a string, not an array. I usually just use the .ToString but it is not working.

View 5 RepliesI'm calling a Windows API that gives me a byte array which represents a unicode string - the problem is that if I call Text.Encoding.ASCII.Get String on it I just get the first letter of the string. The reason for this is that byte array has an empty byte between each character. I've verified that removing these empty bytes resolves the problem by just using a simple For loop to add the bytes that do have a value in into a new byte array, then calling Text.Encoding.ASCII.GetString on that and that gives me the full string I'm expecting.I'm just wondering if there is any easier way of getting the working string though without having to do a loop and create a new byte array etc?
View 2 RepliesI am looking for something that will convert a byte array to a string and back, anything in-build that does it as this method would:
To string:
vb
Dim b = ByteArrSerialize(Obj, Compress, EncryptKey)
Dim sb As New System.Text.StringBuilder
For Each item In b
sb.Append(Chr(item))
Next
To byte:
vb
Dim b(0 To Len(TheString) - 1) As Byte
Dim bCount As Long = 0
For Each item In TheString
b(bCount) = Asc(item)
bCount += 1
Next
I have a string of bytes which I am reading from a microcontroller via a serial port which is as follows : 02 10 18 14 CB 73 43 D3 14 00 0D 00 09 00 1B 00 04 B8 3C 00 00 24 00 30 AB
I would like to write some code to place each the bytes into an array with each element of the array consisting of one byte each.
How can I convert a string into an array?
The values are passed as a string:
Dim strInput as string
strInput = "Tom, John, Jason, Mike"
My error message is: Value of type 'String' cannot be converted to 'System.Array'
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,
{"c", "o", "d", "e"}
How can I do this?
I am trying to do a conversion of a sting to an array name. I have a few arrays called "f2250", "f2255", "f2260" and so on. When a user enters say 2.50 into a textbox, the program needs to be able to reference the f2250 array. Now ive managed to sucessfully code the creation of the string ie "f2250(1)" (Ive added the (1) as a test to refrence an index). How can I use that string to now return the value that is in the array? Does the string need to be converted into something else?

I'm trying to convert a large array to a string, and then back into the array again after sending it over a network connection. No problems with that, but to keep my string as small as possible, I want to convert each array element into a single byte. I know that each element is going to contain a number no bigger than 100, so there will be no problems keeping them all 1 byte long. Problem is, I can't find the correct conversion commands. I think I should use 'Chr' to convert them into a string, but I can't work out how to convert that back into a number at the other end.
View 3 RepliesI want to convert an array of numbers to a string with a colon imbetween splitting it. I tried:
StringA = Join(Array(), ":")
I get the error: 'Number of indices is less than the number of dimensions of the indexed array.'I seem to get this error alot in my programming but don't exactly know what causes it. Even if I can fix this error I heard that Join only works for string arrays so this wouldn't work anyway.
I am working on a mini project that requires me to take a 8 byte hex string that I received from the Serial Port and convert it into a Byte Array and display it on the screen.An example of the string that I receive is 01050001FFFF8FFB
I am currently using the System.Text.ASCIIEncoding.ASCII.GetBytes(str) to help me achieve this. However I realised that if this does not support extended ASCII so whatever byte that is > 7F, I will not get the right value.My current code is as follows:
vb
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
Dim str As String

Okay I am working on a Voice Recognition Application that has a chat bot in it. When voice is recognized it converts the recognized string into an array and checks if the first or last value of the array is either computer or the Bot's Name. However, I am still very new to VB.NET only been programming in it for a few days. (I know ASP and VBscript really well though) When it goes through the check I get an exception how do I fix this? Here's my code with a comment on the line that it fails on:
Private Sub OnReco(ByVal StreamNumber As Integer, ByVal StreamPosition As Object, ByVal RecognitionType As SpeechRecognitionType, ByVal Result As ISpeechRecoResult) Handles RecoContext.Recognition
Dim recoResult As String = Result.PhraseInfo.GetText 'Create a new string, and assign the recognized text to it.

So, I'm creating an array of labels. I have labels set up as:
labal1
label2
label3
etc...
I've declared the array as such:
Dim labelArray(5) As Label
Now, instead of assigning the labels one by one to the array (labelArray(0) = label1, labelArray(1) = label2, etc...), I was hoping to use a loop (there will be more than 5 labels). I have something like this, which obviously doesn't quite work:
For i = 0 To labelArray(i) = "label" & i Next
Is there a function that I can use to convert the labelName string to an object, or have vb.net see that as an object instead of a string?
I have a generic List(Of Customer). The customer class has a name, address, and phone number properties. I also have a property of another class that accepts a customer name array. I am able to do this by doing the following:
Dim names As String()
Dim i As Integer = 0
'customer.GetCustomers is a List(of Customer)
[Code]....
Is there a better way to convert this to a string array?
I have the following function,
Dim results() As Object = Me.Invoke("webdirect", New Object() {Company, LocationCode, CustomerNumber, OrderNumber, OrderRef, OrderDate, WebLines})
o_Company = CType(results(1),System.Nullable(Of Integer))
o_LocationCode = CType(results(2),String)
o_CustomerNumber = CType(results(3),String)
[Code] .....
So the return type of this function is a string, but I would like to get it back to its original form so I can access the individual sections i.e. o_LocationCode,o_CustomerNumber, etc how can I do that ?
Entire functions looks like this
Public Function webdirect(<System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal Company As System.Nullable(Of Integer), <System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal LocationCode As String, <System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal CustomerNumber As String,
[Code] .....
Called like this
Dim returnArray As String
returnArray = client.webdirect(10, "123", "123", "123", "147", "2011-11-1", webLinesArray, 10, "", "", "", "", "", webRespArray)
No errors on run time but the string seems to be just blank, thats why i was wondering how I convert the string back to the array so I can access the individual elements.

I have made an application with a client, server and listener. The server is a console app and the other two are Windows Forms Applications.
Basically i am using a Network Stream to send messages from the client which go through the network to the server which bounces them to the listener which then reads the message and tells the app what to do. (For example if i sent "shutdown", the listener would read it and then execute "shell(shutdown -s)".
The messages are sent like the following SendMessage("shutdown") but when i use a screen capturing API and send from the listener to the client like so SendMessage(background) i get the following error:

i have a string array that i want to output to a text file. the array size is 10000. i fill the array starting from 0 with some strings. at the end, i only want to show the array from index 256 to the last array that is not empty (for eg. if the array is filled with data from 0 to 2000, i only want the text file to show the data from 256 to 2000 and ignore the remaining strings). Is there any function to do this?t i use is shown below

just hoping that someone may be able to assist me to convert system.array to double() array.
Declarations are as follows:
Private f_Data As System.Array
Private f_Measures() As Double
Private f_NumberOfObservations As Integer
I then 'fill' f_Data from a range in an Excel worksheet as follows:
f_Data = wsXLSData.Range(wsXLSData.Cells(1,1), wsXLSData.Cells(8, 1)).Value
This seems to work OK. Upon checking f_Data is indeed filled with 8 double type numbers.
I then try to convert this system.array to a double array as follows:
For i As Integer = 0 To f_NumberOfObservations - 1
f_Measures(i) = f_Data(i + 1, 1).value
Next
I then get an error pointing to the line ' f_Measures(i) = f_Data(i + 1, 1).value' of type MissingMemberException was unhandled by user code'
I've been trying to figure this out for hours now, and I've given up on trying to solve it myself. Basically what I need to do, is convert a "double octet" binary string, such as "11010011 01011101", into a byte or char type if possible.I use the following code to convert my Unicode text into binary:
Private Function ByteToStr(ByVal bt() As Byte) As String
Dim st As New StringBuilder
For Each byt As Byte In bt
[code]....
But that gives me weird results. The "Convert.FromBase64String" obviously isn't what I'm after. Any help would be great. If I can convert the "binary string" into a bytes or chars I can get it into a string.
So I have this
Dim a as string = "Hello"
Dim b as string()
now I want b(0) to have "H", b(1) "e", b(2) "l", and so on.
btw a changes everytime, so don't just say do b(0) = "H"
