I have this as the structure
Public Structure TagInfo
Dim TagName as String
Dim hpt as Integer
[code]....
have the structures are populated and when the form opens up, I make a copy of the structure.on my form i have a textbox... that would have information matching the TagName(x).TagValue I am trying to figure out how i could find that value in my textbox quicker than doing a loop through the tagname structure.
currently working through a project using VB 2008 windows form application and having a little trouble with the code. I need to read data from a text file into an array of a structure, displayed in a list box and have a number of searches conducted on the data and these results displayed on the form. The test data is of rainfall across a number of areas and is in the format:
I have problems with array of structures.my structures are like this
structure order
xxxxxxxxxxx
yyyyyyyyyy
zzzzzzzzzzz
end structure
and then I created many array of structures, like this private arrayorder (100) as order
now i need to sort the entire xxxxxx member of the array of the structure with a function, but I dont want to use loops with arrays indexes to access the information. I want to know if there is another method to reference the array and the member of the structure to get the data.
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 am trying to search the 4 columns of my array by using this click event. The column is determined by a radio button as you can see. I changed my code from last time and now it works, but only for the first column. If i try to search out a string in the second or third columns I get an error based on the line highlighted in blue HTML accutally shows and it is green. the error says Index was outside bounds of array
Like i said It works fine for all values in the first column, accually the second (Numbered 1). If i enter a value in the partsnumBox and it is found in the the 2nd 3rd and 4th columns I want the value in the first column (0) of the same row.

I am wondering whether I can use DataContractJsonSerializer to serialize a Structure type, or does it have to be a reference/Class type? I have the following code:
<Extension()> Public Function ToJSON(ByVal target As Object) As String
Dim serializer = New System.Runtime.Serialization.Json.DataContractJsonSerializer(target.GetType)
Using ms As MemoryStream = New MemoryStream()
serializer.WriteObject(ms, target)
ms.Flush()
[Code]...
And yet if I call it on a Structure type, such as a KeyValuePair(Of T1, T2), I get the following error:
Public member 'ToJSON' on type 'KeyValuePair(Of String,Object)' not found.
Here's the data I'm trying to work with
Spark Plugs
column 1: PR214,PR223,PR224,PR246,PR247,PR248,PR324,PR326,PR444
Brands:
column 2: MR43T,R43,R43N,R46N,R46TS,R46TX,S46,SR46E,47L
column 3: RBL8,RJ6,RN4,RN8,RBL17Y,RBL12-6,J11,XEJ8,H12
column 4L 14K22,14K24,14K30,14K32,14K33,14K35,14K38,14K40,14K44
Here is what i came up with for my code so far
Public Class frmMain
Private strSpark() As String = {"PR214","PR223","PR224","PR246","PR247","PR248","PR324", "PR326","PR444"}
Private strBrands As String(,) = { { } }
End Class
Im currently working in VB2005 so it seems like this was harder to do in that release.
I have a class for a point
Public Class cPoint
Public Speed As Integer
Public Alt As Integer
[Code].....
But that doesn't work in VB2005 much less work with more than 1 filter. I just cant seem to find a good example that works in VB2005. I could iterate through the list but its kind of big and not very efficient.
I have the following
Private Structure FadeLabel
Dim Alpha As Byte

What I'd like to do is 'implement' the BringToFront method so that when I use the 'FadeLabel' structure I can also call it's method 'BringToFront'.
I have two structrures

View 2 RepliesAfter 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 RepliesI am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure).LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file.I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure.When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure,populate the structure from the data file, then call the method to transfer the data back to the website.
How do you recommend I transfer (copy) an instance of a structure from one .NET program to the VB.NET program that executed it?

I'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?
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]....
