IDE :: Creating An Array Of A Structure Based On Existing Project?
May 1, 2009
how to write the code for my project.I am to base my new project on an existing one(existing one has code that works 100%)and create an Array of a structure that bascially holds the information from a summary form AND the totals from an AddToOrder_Click event. If you are still with me)... I cant figure out what the code is for my structure and Array so that I STILL have a Summary Form but I have an array that shows when I click my PrintPreview. So an Array is basically a "space" that holds information, like my summary form except it doesnt show until I click PrintPreview right?
If I just wanted to show the table then my code belongs in the PrintDocument1_PrintPage to show the array but the actual structure code belongs in the Click_Event of my AddToOrder? Please Please understand I AM NOT asking for anyone to write my code, basically I am asking for some clarification on what exactly creating an array from a structure is and therefore determing where the structure is to be placed in my code..

I have a array based on a structure that I want to build a datatable from. Here is what my structure looks like currently,
Public Structure QRQFiles
Public Complex As String
Public DescriptiveName As String[code]....
Since I have a structure with in the structure will I have to define two datatables to represent this?

I want to sort the individuals according to their fitness values descending.
' Declaring a structure
Public Structure AnIndividual
Dim XCoord() As Integer
Dim YCoord() As Integer
Dim FitnessValue As Double
End Structure
[Code] .....
Each individual has a fitness function and has its own X and Y coordinates. I just want to say if individual six (for example) has the lowest fitness value then rank this individual the first one and so on for the rest of individuals.

I seem to be having a problem with controls that I am creating as new classes (not UserControls) inheriting from an existing system control. Everything seems ok while I create the control code, through to the compile (which is successful and adds the control to the toolbox) and dragging the control from the toolbox to the GUI surface. However, when I then debug or compile the project, I get a message such

Is there any performance hit (or other problem) to creating a lot of class and structure types for a project? I'm not talking about the number of objects existing in-memory during runtime; rather just defining a lot of object types during design time. I find myself making a lot of small classes and structures that are little more than simply packaging a few related variables together.

I currently for the life of me can not get this to work.[code]Days(num).openTime(0) = New Date() 'Which gives the same error as openTime @ 0 has not been created as an array object (I'm assuming)Which leaves me completely lost because I've never had issues assigning initializing 1-dimensional arrays but this i just confusing the heck outta me. If anyone knows how I can initialize the 2nd part of the array (Days(num).openTime(0)) I would love to learn from you.

I have to create an array of structure type in VB.net. but I am getting error while marshaling this error. I have to pass this array of structure type in to Dll function.
Code:
Structure declaration:
<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Ansi)> _
Public Structure dx_entry
<MarshalAs(UnmanagedType.ByValTStr, SizeConst:=10)> _
Public dx As String
[Code] .....
I am getting the following error:
An unhandled exception of type 'System.ArgumentException' occurred in Audit_Demo_2307.exe
Additional information: Type dx_entry[] can not be marshaled as an unmanaged structure; no meaningful size or offset can be computed.

I have a SQL database which I'm running a query against to return a list of names - eg using "select names from table"I would like to add all of these names to an array so I can use them later. To do this I would need to use a dynamic array as the number of names returned could be anything.Apart from first running "select count(names) from table", getting a value and then Redim'ing the array on the count is there another method I can use.I've seen there's a dataset row.count? Can I somehow use this?
connection.Open()
reader = command.ExecuteReader()
While reader.Read()

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

I've been searching for a while now and can't find a way to add a constructor to the Rectangle Structure.
Is this even possible without inheriting from the class?

What I am wondering is, is it possible to create an enum and attach it to the DateTime structure? Extension Methods come instantly to mind, but I don't know of a way to pull this off using them.
Dim july As DateTime.Months = DateTime.Months.July
Public Enum Months
January = 1

I am creating an Add-In that I want to create classes and forms based on a database structure. I can't find any information anywhere on how to programatically add code to classes. I know I can write out the files and add them to a project, but that would limit what I can do in the future. I would like the possibility to update a function in the future which would be impossible writing out a file and loading the whole thing back in. It would destroy any modifications made to the class, and since this Add-In will only be creating a framework, there will usually be modifications.
I got this line from the macro recorder:DTE.ActiveDocument.Selection.text = strDACode
But I like to keep Option Strict on, and this is late bound according to the IDE. There seems to be very little help on the IDE and how to use it creating Add-Ins. If I overlooked something please point me there, but I can find nothing. I don't know if it can be done, but I was able to do it in an Add-In for VB6.I would also like to add controls to a form, so if anyone can point me somewhere where it explains
