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:

Public Structure dx_entry
<MarshalAs(UnmanagedType.ByValTStr, SizeConst:=10)> _
Public dx As String
[Code] .....

I am getting the following error:

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..

Set Array Size For All Variables Using Same Structure / Type

Oct 30, 2010

I found out that you cannot set the array size for a structure when you are making it, i.e

[Code]...

I have to fix this by making a variable with type made by Structure bullet and then redimming it, i.e

[Code]...

This means for every variable with the bullet type i create i have to redim. Is there a way i can set the size of .mesh with .capacity for every single variable created with the bullet type automatically?

Best Structure To Hold 'array Of Arrays' Type Of Data That's Also Searchable

Mar 4, 2010

I have a database table of company information.It's about 50 records and contains things like company id, company name, address, phone number, shipping rate1, shipping rate2,etc.I want to load that table into a structure that I can quickly search within my code.I want to search by id to find the company, and then use the company's data to update some records.My lazy way has always been to add a listbox for each piece of data, then do an indexof on the id, then access the same index on the other listboxes.[code]

Type Not Defined Error When Creating Class

Feb 26, 2012

First I put it inside a Module and it works just fine. However when I created a Class and put it inside it, it showed up some errors. (they are in the code's comments)

Public Class MyImageClass
'function to merge 2 images into one
Public Function Merge(ByVal img1 As Image, ByVal img2 As Image) As Image 'Type 'Image' is not defined
Dim bmp As New Bitmap(Math.Max(img1.Width, img2.Width), img1.Height + img2.Height) 'Type 'Bitmap' is not defined
[Code] .....

I tried importing the System.Drawing namespace to this class which didn't change anything either. I've never really touched the OOP side of VB.NET before, this is my first attempt creating a class.

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

Error: "The Specified Type Must Be A Structure Containing No References"

May 9, 2010

I have created a structure with the following elements:

<StructLayout(LayoutKind.Sequential)> Public Structure person
Public userid As Integer
Public age As Integer

[code]....

I am trying to write this structure using the following lines of code:

Sub testwrite(ByVal filename as string)
Dim temp as new person
Using mmf = MemoryMappedFile.CreateFromFile(filename, System.IO.FileMode.OpenOrCreate, "test", 1000)

[code]....

However, every time I try and run the program I get the following error: "The specified Type must be a structure containing no references."I thought the "MarshalAs" created the array within the structure and therefore wasn't a reference. Can someone tell me how to get round this problem so that I can pass an array.

Error: Value Of Type Cannot Be Converted To 1 Dimensional Array Of String

Sep 29, 2008

[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.

I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.

VS 2008 - User Can Retrieve Value In Any Numeric Array Type Rather Than Specifying An Array Type

I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values. I wanted user to pass any numeric array (e.g. integer,single,double,long) and I could return values in that format.
