View 1 RepliesI 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]....

I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

I have a database structure filled with data that I'm trying to write out to an XML file. Here's a taste of the way the VB code is structured:[code]I can't see or report any progress, because the processing is all tied to one giant LINQ query. Even if I can't make it any faster, I'd like to know how much longer I have to wait. My first version of this code had For loops instead of queries, so I could display progress, but it took a loot longer.Obviously I'd like to speed this up considerably. It seems like there should be a simpler way to convert the data to an XML file, especially since the database structure was created from the XSD in the first place.

I am using this to copy tables in an Access database(2003). the questions I have are:
1. How can I make this more 'obejct oriented'?
2. How can I copy just the structure of the tables and not the data?
(Currently both are occuring)
Just suppose that I define a structure, and an array such as
Structure Person
Dim First_Name as String
Dim Last_Name as String
[code]....
Can I fill in my list of people using a single line of code for each record? Something like this, it doesn't work, but this shows the sort of thing I mean.
My_List(0) = {'John', 'Smith', 24, '555-1234'}
My_List(1) = {'George', 'Jones', 31, '555-8123'}
My_List(2) = {'Tom', 'Green', 40, '555-3434'}
It's easy enough to fill it in line by line. I could do that without problem. But I want to be able to look at the code and see the contents of each line. Doing it as above would make it easier to read.I could make it a multidimensional array of strings, rather than a structure.If it makes any difference I'm using Visual Basic 2005 Express Edition.

I'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.
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
