[2005] Copy Array(of Class) To Another
Mar 12, 2009
I am trying to copy an Array(of Class) to another Array(of Class). The Class really just holds 3 values together, so it's basically a string. I thought just something like this would work
[Code]....
But that literally makes Array1 access the contents of 2, but I want it to be a separate copy. I'm currently using a simple loop procedure to copy contents but I was hoping there was a command for it. I looked at .Item but there didn't seem to be anything there.

I have a one-dimensional array that has one number per element. I also have a variable number, var. I need to take the number of elements from the first array that equals the var and put it into a second array with commas between the numbers. I would also like to have a title element in the second array. [Code]

I wrote a function that copies the properties of one class to another so make a copy of an object.So something like
MyObject myObject = myOtherObject.MyCustomCopy(myObject)
where myObject and myOtherObject are of the same type. I do it by bascually doing
myObject.prop1 = myOtherObject.prop1
[code]....
I am pretty sure in the past I used a .NET object that automaticaly did this, by reflection I guess, but can't remember it ... or an I imagining that such a method exists?

I'm attempting to copy a rather complex form from one part of my project and use it (modified) within another part (ie, depending on whether it's maintenance or an outage, you'll get a slightly different email screen).
My first attempt failed miserably, as I had simply right-clicked and pasted the form within the project, assuming renaming the controls would work. nope, I didn't realise that there was stuff in the original form that was renamed as well, and that created a monstrous pile of errors.My second through fourth attempts also failed, generating errors in forms that (I thought) weren't related or connected. Once I deleted the copied form, all was fine.
So, short of trying to rebuild the form from scratch (using a different naming convention for my controls etc.), is there a simple way of doing this? This seems to be such a simple task, but alas I was wrong....(or, at least it's not easy with the information I have right now.

I'm designing a small GUI Windows program that allow staff at a cinema to reserve seats for customers. There will be a total of 60 seats in the cinema. I have two classes in my program:-
1.) MainForm.vb - used for I/O actions and user interaction
2.) SeatManager.vb - used to hold and handle the background methods and functions that make the program work
Here is the code for my MainForm.vb class thusfar:-
Public Class MainForm
Private Const m_totalNumberOfSeats As Integer = 60
Private m_seatManager As SeatManager
[Code]....
Basically, when the program opens, the lstReservations list in the MainForm class will be populated with a total of 60 (m_totalNumberOfSeats) entries to represent 60 seats. Each of these seats will contain the index number from the array m_nameList; this index number (+1) will represent the seat number and then in the lstReservations list, after the seat number, I'd like it to contain the respective entry from the m_nameList array. As all entries will be held in RAM, when the GUI is opened, all m_nameList array entries will be empty. As the user uses the program, they can highlight a row in the lstReservations list and then use the GUI textboxes to enter the customer's name which will then be populated into the respective array entry.
how to, when the GUI opens, ensure that the lstReservations list takes all of the blank entries from the m_nameList array and from there, I can highlight a row to carry out further methods on?

What is the difference between using the 'array' class in VB and just declaring an array like normal. In other words, what is the difference between:
Dim numOfTicketsPerDay As Array
Dim intNumOfTicketsPerDay(6)
As Integer
Is there any preference of when one should be used over another?

I have created a form with a tab control that I want to be able to make a copy of in such a way that all the child controls and their data are copied as well. I have tried this:
Dim NewPage as TabPage = tcViews.TabPages.Item(0)
tcViews.TabPages.Add(NewPage)
I end up with a reference to the first page. That is, if I change something in the old page, it changes in the new one as well. I believe this is because VB.NET treats assignments of classes as references, rather than values. Hence only the memory address of the original is copied, so essentially both refer to the same tab page in memory. I also tried serialization and deserialization.
The TabPage is apparently not serializable. And I heard about MemberwiseClone, but it isn't accessible, according to Visual Studio. There doesn't appear to be a Clone method available either. How do I make a new tab page that is totally independent of the original, but that has copies of the original page's controls and their property data, which can then be edited independently of the originals?

I am looking for a way to create Volume Shadow Copies of individual files. I have searched accross the net now for classes and code to use but I haven't been able to find anything. I'm only really starting out in .NET and C#, C++ or any other language for that matter are completely alien to me. Everything I've found on the subject, even from Microsoft VSS SDK is either in C# or in C++. I don't want to use any external programs, everything must run from the single exe file.
Target End Result:
I'd like a file at "\global\class\VSSClass.vb" that houses all the code needed.
Public objVSSClassObject As New VSSClass
For in-line code I'd like it as streamined as possible as it will be used with arrays of pre-set filenames.
objVSSClassObject.CopyFile(srcFile, dstDirectory)
Here's a sample of how the code would be used.
Public VSS As New VSSClass
Dim dstDirectory = My.Computer.FileSystem.SpecialDirectories.Desktop & "\Shadow Files"
Dim FilesArray() As String = {"absolute_path_to_file1.txt", _

Part ot my program is to simple copy a range of cells ~21 000 rows from one WB (oSH) and copy it to another WB (oSHOut).I've red a lot of posts,tried a lot of variants, but nothing helps..Strange here is that if I copy less than 8500 rows, the paste to the destination range is OK.But if I copy the whole range ~21000 rows, vb.net trigers an error - "Copy method of Range class failed".So I tried to do this in several parts - 1 row to 8000, 8001 to 16000 ect.The first copy-paste works OK, on the secon - there's an error.[code]

I would like to make a "deep copy" of a class object that I have defined. See Visual Basic 2005 Code below
Dim MyStuff1 as new MyClass
Dim MyStuff2 as new MyClass
mystuff1.getbyID(anID)
mystuff2 = mystuff1
Unfortunately the statement "mystuff2 = mystuff1" makes a "shallow copy" of mystuff1. Therefore, if mystuff1 is redefined then so is mystuff2. What do I have to do in MyClass to implement a deep copy method such that operations on mystuff1 and mystuff2 are independent?I would prefer something like
mystuff1.deepcopy(mystuff2)
or
mystuff2 = mystuff1.deepcopy()
