Get The Number Of Items Or Size Of Items In The Recycle Bin?
Dec 14, 2011
I've got some old code of mine that I'm going back to and updating a little bit. On one part of it I need to check if there are any items in the recycle bin or not.
This is the code I was using to accomplish this:
vbcode
Private Declare Function SHQueryRecycleBin Lib "shell32.dll" Alias "SHQueryRecycleBinA" (ByVal pszRootPath As String, ByRef pSHQueryRBInfo As SHQUERYRBINFO) As Long
Private Structure ULARGE_INTEGER
[Code]....
The msgbox and end is just in there for debugging purposes. This always returns all 0s, even when I know that there is something in the recycle bin.

When you use array.length you get the size of the array and not the number of items in it.
For example:
Dim MyArray(10) as String
MyArray(0) = "Potato's"
MyArray(1) = "with"
MyArray(2) = "salt!"
MyArray.Length will return 11
How do I get the number 3? I am creating a class library so it's kinda hard to keep testing all kinds of methods until I get the right one .

I am writing a clean up program to use in my computer repair business. I have been searching this site as well as Google to find an answer for how to get the size of the recycle bin. I would also like to be able to empty the recycle bin as well. I have not programmed in visual basic since VB6 so I am relearning the language.

My visual studio 2005 has been running great up till now The menu items in the menu toolbar display exactly as follows:File File Edit Edit View View File File Edit Edit View View Tools Tools Tools Tools Window Window Community Community Help Help Window Window Community Community Help Help
Error List is displayed as follows:(I've excluded the icons)0 Errors 0 Errors 0 Warnings 0 Warnings 0 Messages 0 Messages The standard toolbar images are also displayed in 'duplicate'
This is before I open a project and visual studio is on the start page. The 'duplicates' do not go away even when a project is open.When project is open, Solution explorer displays duplicate images as well
I've tried all the following but still cannot get it to display normally. Restored my computer to a time when it was working ok. Full scan on my computer with AVG premium which includes spyware etc (No viruses , etc found) All software is updated fully

I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?

I have a listbox, textbox, and a button. every time I push the button, an item from the listbox is put into the textbox. when the button is pushed again, it grabs the next item in order and puts it into the textbox. so on and so on until it gets to the last item. once I get to the last item it keeps repeating the last item over and over again. SO what I was wondering is how do I get a messagebox or some sort of checker to tell me when it has moved the last item from my listbox to the textbox?? PS textbox2.text=0 and every time the button is pushed another number is added to the value of textbox2.text. so basically if I could figure out how to grab the value of lines at any given time in listbox I could call a msgbox up!! here is the code I am currently using[code]...

Does anyone know how to add a limit to the number of items in a list box? For example, you can't add more than 10 items in ListBox1.

i have 1 button, 1 listbox and 1 textbox.this is my code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ListBox1.Items.Clear()
Dim finish As Integer = TextBox1.Text
[code]....
if i set the sorted property of listbox1 to true that code will add 0 before the inputted number so that the sorted property in listbox1 will be usefull in sorting integers.
for example i have 1,15,30,36
it will make 001,015,030,036
thats what i think am not sure because i cant edit the code so that it will work in my program.

I'm trying switch from using arraylist to arrays. Seams like arrays are not as easy to use when you don't know the size of the array.
Is it possible to use an array without having to specify the size of the array like in this example?

Would it be possible to list the number of items in a rich text box? Each item starts on a new line. Something like the following but obviously for a rtb.
TextBox1.Text = ListBox1.Items.Count

I am frustrated with this. Please help. I wanna do it like this:=Iif((Fields!Qty.Value * Fields!UnitCost.Value) + Val(reportitems!txtTUC.Value) = 0.00, "-", (Fields!Qty.Value * Fields!UnitCost.Value) + Val(reportitems!txtTUC.Value))
Is it invalid to multiply different types of item? if so, how can I make it? I just want to get the sum of (UnitCost * Quantity) to be the value of txtTUC.

Certain areas of my tab control have become what seams to be transparent using Visual Basic Express 2010. I can rearange items in the tab, except in certain blackhole like areas. When I move a item within the blackhole area or move a item to the blackhole area it disapears to another tab. I can move items out of the blackhole region and they sit where I put them.

So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

I'm trying to figure out a good way of implementing a List(Of) that holds a maximum number of records.
I have a List(Of Int32) - it's being populated every 2 seconds with a new Int32 item.
I want to store only the most current 2000 items.How can I make the list hold a maximum of 2000 items, then when the 2001'th item is attempted to be added, the List drops the 2000'th item (resulting in the current total being 1999).
Thing is, I need to make sure I'm dropping only the oldest item and adding a new item into the List.

I am trying to get the number of items that are checked in my CheckedListbox. The Items.Count seens to only reference the entire collection so I am not sure how to narrow the count down to only the ones with checked boxes.

I'm gonna add x number of items to a listbox in form #2 form form #1. When I click the button it opens Form #2 and then I tried this code (which makes the form freeze):
Dim qwe As Integer = 1
Do Until qwe = regKey.GetValue("Count") + 1
PrMaker.ListView1.Items.Add(regKey.GetValue(qwe))
qwe = qwe + 1
Loop
The regKey.GetValue("Count") is a registry key which contains a integer (unknown). What is wrong, or is there another, better way, of doing this?

When you have a single dim array, you get number of items in with simple Ubound(array). What is the most efficient way, to get number of items in each "column" in 2 dimensional array? My code (part):
.NET
Public Shared LoopStock()() As LoopStockDef
Public Structure LoopStockDef
Dim EntID As Int32
Dim LoopNo As Int16
Dim LoopType As String
Dim loopStPtX As Int32
[Code] .....
You can't Ubound multidimensional array as you can do with single dimensional array, as the second dimension can have different number of items in each column (DimX in the following table)
DimX | (1) | (2) | (3) | (4) | (5) |
-----------------------------------------------
DimY | | | | | |
(1) | 45 | 41 | 15 | 48 | 49 |
(2) | 35 | 26 | 98 | 15 | 31 |
(3) | 12 | 23 | 36 | 69 | |
(4) | 88 | | 26 | 28 | |
(5) | 74 | | 89 | | |
(6) | 36 | | 25 | | |
If you do
.NET
UBound(LoopStock, 2)
You get size of 2nd dimension, not number of items in the table for particular column. The best solution which comes to my mind is to define another array, a multidimensional counter, like
.NET
LoopStockDims() As Int16
And count every added item for each column. Is this the best way?
