This works fine, unless I have Windows Explorer open and I'm looking at the 'MySubFolder' directory.

Converting Structure Within Structure To Byte Array For Socket
Aug 29, 2009I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.

Sort A Structure With Preserving The Position Of Similar Numbers?
Oct 28, 2010I am using structures in my programming and I sort the structure according to a value in the structure using IComparer.This is a simple example for what I want.
Dim MyArray(6) As Integer
MyArray(0) = 1
MyArray(1) = 45
[code]....
How does number 1 get sorted? Is it brings the newest 1 to top or keeps the old 1in the same index? In my original example (before sorting), MyArray(0) = 1 and after sorting MyArray(0) = 1.Is this the same original 1 or this another 1 (the newest one added to the array) moved to that position?In case the MyArray(0) = 1 after sorting should be MyArray(5) = 1 before sorting.
Here is my a sample of my Code:
Public Structure ToSolve
Dim Con(,) As Integer
Dim Discharge(,) As Double
[code]....
Using all these methods, how can I preserve the positions of similar number in the list? i.e. I want to bring the newest 'Similar' value to the top of the list.

Array Or ArrayList Or Structure In An Array?
Nov 9, 2010After gathering the Machine names on the (sealed) LAn i am then getting the ip addresses, MAc address and Macine User name of each machine on the LAn..These details will need to be accessed seperately for use in the security testing and i am unsure how best to store the active data (though eventually in a database) Am i best to create a Multidimensinal arrayList or array(bearing in mind that all the data is convereted to "String" (arrays can only store one data type??) The data found on the live network is allways changing making an array a difficult choice? I have read some tutorials mentioning making a structure with the data and storing this in an arraylist but i dont know whether this will make accessing the individual data items (ip,MAc,HostName etc) a difficult procedure?
View 1 Replies.net - Array Defaulting To 'nothing' Rather Than '0' In Structure?
Mar 29, 2012I'm currently stuck on an issue regarding declaring an array of type short in a structure and having it default to 'nothing' rather than '0' after ReDim.'Declaring array and setting it's initial size
Private Structure Totals_T
Dim sTot_Desc As String
<VBFixedArray(10)> Dim iTot_Cnt() As Short
Public Sub Initialize()
ReDim iTot_Cnt(10)
End Sub
[Code]...
When calling m_Totals(0) the arrays returned have 10 records in the arry with sTot_Desc and iTot_Cnt having values of nothing in all records. When I ReDim m_Totals both the variables I declared in the structure(sTot_Desc and iTot_Cnt) are declared as nothing, it's fine for the String but I need the Short I declared to be declared as '0', which is what I thought happens when you ReDim. Can anyone see what's going on here and why it's declaring my variables as 'nothing' rather than defaulting to '0' for the short and ""/nothing for the string?
Code An Array Of Structure?
Mar 26, 2009I am once again struggling with my weekly project. I am assigned to write a program that converts a predetermined english sentence to both french and german. The code is to contain an Array and a structure. Also we have not covered retrieving array data from a TXT file, so we are to hard code in the array data. I coded the structure and the array, I added the array data, but am confused how to access the data. The examples I have found all deal with retrieving data from a TXT file. Can someone give me a nudge in the right direction.[code]....
