VS 2008 : List FTP Dir In VB?
Jun 11, 2009
This should hopefully be a simple one. I want to list the files and file sizes of a directory on an ftp. I have absolutely no clue how to get into an ftp with VB.I made a batch script that does this but batch can't do the math to convert the file size from bytes to either kb, mb, or gb.
So all I need is to learn is how to get the file names and sizes (other things such as date, owner, permission would be nice to know also) then I can get it to write a file in the format I want. I figure I'll use arguments to choose the directory or if no argument is used root will be listed.

This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!

I think (?) this is about object design, and perhaps about structural and/or creational patterns. But a bit hard to say when I only know a couple of patterns yet.[code]But... what if we INSTEAD want each Product instance only to (in some way) refer to one instance of a specific list of Components. So we wan't to save the products list to one file, and the components list to another file. Then would I build the objects the same way, or different? So let's then say we have now Class B as below. [code]
1. Will not need to update each component variable of the products list when the components list changes.
2. If the Product object shall be shown in a DataGridView, for editing properties, it seems easier to implement the selection of the component property.
Is this wrong approach? Is it suitable in some cases, and if so, when? Are there other solutions I perhaps am not aware of that would be appropriate? Is this about structural design patterns? and if so, can the alternatives above be catagorized to some pattern type? I don't really know exactly what I'm looking for.. But I think probably I'm looking to understand whether the object design will be determined by the way the objects are saved.. And if i shall save the objects by serializing to file, vs saving to a database, would I create the business objects differently?

Ok i'm trying to declare a global list of type T (or is it <anonymous type>) i declare it in a module with something like Friend query As New List(of {whatever type i try}) the app takes some xml and parses it into a list but i need this list available to other classes and methods within the app, everything i have tried fails resulting in an error like Value of type 'System.Collections.Generic.List(Of <anonymous type>)' cannot be converted to 'System.Collections.Generic.List(Of {whatever type i try})'.
What would be the correct way to declare a list of this type? is there another way i could do this?

Firstly i apologise for another topic on a subject i have created already but this is a slightly different question and not related to LINQ at all despite the fact the code uses LINQ (the linq works fine and creates a List(Of Test) where each 'Test' contains a List(Of TestList) This data could be anything i guess and could come from an array or a database rather than xml literals.Ok, essentially i have a list which contains a list and i wish to display all the properties (List and list within this List) onto a DataRepeater Control. I have developed a testbed to get this working so i can implement it into my main application. Firstly I'll show the current code and how to construct the form and after that i will explain what i have tried and what i have had happen from these trials over the last week.
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

when I add a Control to the List(Of Control) what gets added to the List? Is it the Control or reference to the Control.I have a collection of controls (picture boxes representing notes,comments, icons, etc.), which can be drag and drop into other picture boxes holding read only images. Those controls are never permamently added to those images, they can be move or dispose as needed. I need to save those controls to a file and retrieve it later, however when retrieved, they must be place onto the same location in the image. Saving just the image is not the option, I also need to save all the control attributes.

I want to create an app that is constantly running and as part of my desktop toolbar. When I mouse over the icon, I want the list to show in front of all other windows on the screan. I, also, want it to fade away once the mouse leaves the icon.If the icon is clicked, the window displays.
I want to be able to click-and-hold the title bar to move it around when the window is displayed. I want the full display of the window to be a check box list with each line being ~25 characters long. At the top of the window, there should always be an open line on top of the list where I can enter a new "task," and hitting the "ENTER" key will save the line and move it down one line, as well as the entire list underneath
The action of ENTERing a new "task" should spawn a new open line at the top of the checkbox where the user can enter a new task. When a box (located to the left in front of each line of text) is checked for a line, that line will disappear."Checking" a box should move every line underneath of the Checked (and thus deleted) line up one line. There should be a "close" or "minimize" (depending on how you keep in to the task bar) button the hide the app when I'm through using it.

I used an array for collecting data throughout my program. With "Redim Preserve" I increase the size along the way. However I understand that this method is not really efficient and recommended is to use: List
So I tried (simplified here):
[Code]...
But the line: "ExtInfo(indx).Done = True" produces an error: "Expression is a value and therefore cannot be the target of an assignment."Clearly I don't understand fully the concept of "List(Of T)"...

Heres my issue which has been bugging me all day and i haven't been able to resolve.
I have a DGV on a form (frmResults) this is linked to a bindingsource of type InventoryItem (popInventory is a list(of InventoryItem) and popular is a list of another class object (StockItem). here's some code to explain better
first the declarations in my globals module
Public Module globals
Friend popInventory As New InventoryItem
Friend popStock As New StockItem
[Code].....
ok what this routine is doing is on the results form is 2 dgv's the first contains stock to keep, the 2nd one contains excess stock to sell. what i get however is all cells on both DGV's are the last item to be read from the popular list. the items are adding correctly (varified with a breakpoint and looking at variables at the time. the popInventory item is added to the relevent List.

I need to access a list of attributes as follows.I'm drawing a curve named "CurveName". With Curvename I need to access the curve color, the data symbol etc.I tried this:
Dim cllCurveAtt as new cllCurveAtt
sub SetAtt
cllCurveAtt.Add(CurveName, "Color.Red")
......
end sub
If I then want to refer to the curve color through cllCurveAtt(CurveName) I get an error because "Color.Red" is not a system color, it should be Color.Red without the quotes. But if I remove the quotes in the assignment THAT causes an error because since CurveName is a string, that color thing should also be convertable to a string. Catch 22.

I am making a program that when you click a checkbox it will add a corresponding list of items to a textbox. The only problem is that I have lists that are about 20-30 lines long, and all I know how to do is items.add "item" I was wondering if any one knew a way that I could add a long list without out items.add.
Here is a sample
Private Sub CheckBoxes_CheckedChanged() Handles CheckBox3.CheckedChanged, _
CheckBox2.CheckedChanged, _
CheckBox1.CheckedChanged
