I have a structure which includes this...
Structure MasterStruct
<VBFixedArray(98)>
End Structure
When I create the code to initialize the Sections array like this...
Dim MasterX as MasterStruct
Dim Temp as Integer
For Temp = 0 To 98
MasterX.Sections(Temp) = 0
Next
VS 2008 tells me that MasterX.Sections "is not an array or method, and cannot have an argument list."

I desperately seek for a code sample to serialize an array of structure elements to a XML. To serialize a simple object of a structure I used:
Private Sub saveEntries()
Dim FS As New FileStream(path, FileMode.Create)
Dim XS As New XmlSerializer(GetType(personEntry))
XS.Serialize(FS, entries(0)) 'serialize first entry of an array - success
FS.Close()
End Sub
Structure looks like this:
<Serializable()> Public Structure personEntry
Dim name As String
Dim d, m, y As Integer
End Structure
Private path As String = "data_file.xml"
Public entries(2) As personEntry
But how to apply this to an array?
I 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.

I'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.
View 6 RepliesI am trying to create and initialize an array of structures of a fixed size. Each struct will be populated when a button is clicked. Here is an example of my struct:

Whenever a specific button is clicked, I am trying to collect data and store it in the respective struct and so for example, if button 1 is clicked then I will store the data associated with button 1 into BtnStruct(0). The position of the button is stored in a public variable called BtnNum. If I attempt to store information in the struct inside another function as follows, I receive an error
BtnStruct(BtnNum).x(pos - 1) = temp "btnstruct is not declared. it may not be inaccessible due to its protection level"

After 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?

Private Structure Totals_T
Dim sTot_Desc As String
<VBFixedArray(10)> Dim iTot_Cnt() As Short

ReDim iTot_Cnt(10)
End Sub

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?
I 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]....
