I want to put all elements of a String array into a Queue(Of String). I have following code which using For...Each to put string into Queue(Of String):
Dim Files() As String = OpenFileDialog1.FileNames
'OpenFileDialog1 is an instance of OpenFileDialog control
Dim PendingFiles As New Queue(Of String)
[code]....
Is that possible to do it (i.e. put string array into Queue(Of String)) without using For...Each?

View 2 RepliesI read a line from a text file with text as "ABC.txt", "XYZ.txt", "TEST.txt".I use code file = sr.ReadLine(); to assign the text to variable file. Now I want to initiate a string array likestring[] FileNames = {file}; it doesn't work. What should I do?
View 2 RepliesLet's say I have regular string called tempstring, and I want to change a specific item in that string. Like if tempstring = ";1;2;3" and I want to change the "2" to "Baboon." Here's my best solution on how to do it:
vb
Tempstring = ";1;2;3"
'Datasplit tempstring
Dim datasplit As String() = Tempstring.Split(New Char() {";"c})
[Code]....
This works, however, it feels a little heavy. Is there an easier way to do this? Perhaps a way to directly replace datasplits without readding them all to another string one by one using a loop?
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.
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 expected the recieveQueue function to copy the queue passed to it into the waiting queue, then it allows me to use the waiting queue contents as I want. But when I try to use it, around this line I get the error, 'queue empty' < If waiting.Count > 0 And waiting.Peek <> "" Then >
I'm trying to improve performance of an application by introducing threading (see my earlier question). I have filled a Queue(of String) with XML messages and I now want to setup two threads to post these messages to a webserver). This process needs to ensure that each message is only posted once. Would a BackgroundWorker (or two) be suitable for this?
View 2 RepliesI want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

Is there a way to use the string.split command to get a section of a string without using an intermediary array?for example, if my string is "1 2" and I want to get the "2" part using string.split(" "), is there a way to avoid creating a new array, and just get the bit of the string I want in a single line?

I want to take a string from a text box and split each letter of the string into an array. Then, I want to take the first item in the array(the first letter of the string)and capitalize it. Once I've done all that, I want to combine the array and convert it back to the original string it was, except I want the first letter to be capitalized(I've already placed this into a variable.)
Here's what I've come up with so far:
