Define An Assignment Operator In Structure?

Jul 9, 2010

I am having a structure that is actually a simple byte with more functionality.[code]...

If there would be a way to inherit from Structure I would simply inherit from Byte adding my functionality, basically I just need a byte Structure with custom functionality.

My question is also valid when you want to define your new singleton member value-types (like, you want to define a nibble-type for instance etc.) and you want to be able to set it with an assignment to number or other language typed representation.

Converting Structure Within Structure To Byte Array For Socket

Aug 29, 2009

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.

Public Structure MESSAGETYPE_OIP_Login
Dim Header() As COMMANDHEADER
Dim UserName() As PSTRING

Define A Property In Class Which Is An Array (of Doubles)?

Feb 6, 2012

I need to define a property in my class which is an array (of doubles).My original (bad) version is this:

Public Class Market
Property Correlations0 As Double
Property Correlations1 As Double
Property Correlations2 As Double

[code].....

This however doesn't work. I get an error already at design time: "Public Property Correlations as Double has no parameters and its return type cannot be indexed."What should I do with it? I also do not know in advance how large the array should be (the array size is determined at runtime based on other properties).

Define An Array Inside Of The Sub Call Parentheses?

Mar 22, 2011

Is there a way to define an array inside of the sub call parentheses?

Private Sub sub_name(byval sString, arrString)
sub_name("Some Text", array.{"","",""})

What I've been doing is passing a string and using a split on it to break it into an array in the Sub/Function, but I was wondering if there was a way to make the array inside the parentheses. I've looked through Google, but I'm guessing I'm not asking the right questions or it's not possible.

Updating Array Length While Looping Array

Oct 9, 2009

I am working on a code that should capture the color of a pixel in a bitmap and then check if the 8 surrounding pixels have the same color. If the checked surrounding pixel HAS NOT the same color it will be ignored, otherwise if it HAS the same color, it should check for its own 8 surrounding pixels and so on.

To do that, I have created an array that starts with a single entry (the x,y coordinates of the initial pixel). So, when a pixel with the same color is found it is pushed to the end of the array. I used a for each loop supposing that VB would keep looping until the end of my array - and since it is growing, the last position of the array would be always pushed until I have not more pixels to be checked.

The problem is that VB is not respecting it, and is considering my array as if it had just 1 entry. Seems that it catch the size of the array when it enters the loop, and regardless the fact I have pushed new items to the array it doesnt keep looping it.

How can I force VB to update the end of array position while looping it? Although I think it wouldnt be necessary, here it goes the code I have so far...

Array Or ArrayList Or Structure In An Array?

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?

Marshal Variable Length Array?

Jun 8, 2010

I'm trying to call the GetInterfaceInfo Windows API - it accepts a structure as one of its parameters and this structure has a member that is an array. The API populates the contents of the array when it is called and there can be any number of items in the array. How can I define such an array in my structure?

If I just use a normal .NET array like so then the program just crashes (no exception thrown)

<StructLayoutAttribute(LayoutKind.Sequential)> _
Public Structure IP_INTERFACE_INFO
Public NumAdapters As Integer

[Code]...

and this works fine, but the problem is I have to define the SizeConst attribute as you can see to something large (64 in this example) so that the API doesnt fail because the array wasnt big enough. Firstly this is a waste of memory as in most cases the number of items the API sticks in the array will be less than 10, but secondly if there was ever a case where the API wanted to put more than 64 items in then it would fail.

Using ReDim to set the length of the array at runtime seems to have no effect, and that SizeConst attribute has to be set to a constant value so there's no way I can dynamically set it.
