Selecting Items From Checked Listbox
Jun 27, 2012
Should: take items and fill checked list box with possible tours that the company can receive (this is done and working) i.e. for 2012, Titleist gets X, Y, and Z; so there are two checked listboxes for 2012: lvl 1 and lvl 2, username specific Both have lists "X, Y, Z" in that order, lvl 1 and 2 is for the permissions level, 1 is lvl 1 and 2 is alex's 0 marking for full details code goes through and checks if lvl 1 is marked, if so it checks the tour in the lvl1 check box if zero is marked, finds the tour in lvl 2 and lvl 1 and checks both items if a tour exists for company but not for the user, the checkbox exists but neither is checked

Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.

I have a simple ASPX page with a listbox and a button. Listbox has about 8-10 items in it. After the user selects an item (listbox is multi-select) and clicks the button, I'm iterating through the items to get the selected one like so:
For Each Item As ListItem In lstLetters.Items
If Item.Selected Then
Dim LetterID As String[code]....
When I step through the code, I select the first item from the listbox. I setup a watch on the 'Item' variable. The code will iterate through each of the items -- but Item.Selected always reads 'False'.I double-check the page, and sure enough my item is selected on the form.What the heck is going on?

How do I express, in the code, all the items in the textbox? So far all I could come up with was this:
Dim x
Me.Listbox1.Items.Item(x)
But it isn't working.

I am reading information on missed deadlines from a database. For each missed deadline I add a item to the checked listbox and store the deadline's information in an array. I now want to disiplay all the selected (in the checkedlistbox) deadlines' information in another control, but at the moment I am getting an error. This is the code I am currently using to check which items have been selected
Dim x as integer
For x = o to array.count - 1 do
If checkedlistbox.GetItemChecked(x) = true do
'Here I am displaying array.item(x)'s information in the other control
end if
next
1) Say I have five items in the checked list box and I select all five items, when it gets to x= 3 it gives me the following error "ARGUMENT OUT OF RANGE EXCEPTION was unhandled: InvalidArgument=Value of '3' is not valid for 'index'. Parameter name: index"
2) Say I have five items in the checked list box and I select ONLY the first two items, when it gets to x=4 it gives me the same error as above only for the number 4.
I have tried the methods/functions GetItemCheckedState, SelectedIndices and GetSelected as well, but they all give the same or similar errors. According to me the index cannot be out of range as I have five items in the checkedlistbox as well as the array.

I know that I can select an option in a listbox within my HTMLDocument (which refers to a webbrowser control's HTMLDocument) using SetAttribute. For example:
htDoc.GetElementById("lstCountries").SetAttribute("value", "88")
However, I can't figure out how I can select multiple items within the listbox. When I call SetAttribute repeatedly, it always unselects the old one first.

I am trying to display multiple check items from a listbox into a label seperated by a comma. Everything is working fine but the only problem is that when i check first item in the listbox nothing happens and when i check the second item then the label shows the first item. Then when i click third item the label shows the first and the second item and so on. When i uncheck the item it does the same
My question is why it does not show the items in the label as they are selected.

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 am able to have checked menu items show the variables that I need to show, but they don't uncheck themselves unless I go back and click them. I want to have only one checkmark on a country at a time...is there any way? I've tried if...elseif , but that doesn't work....example below (If I only want Mexico checked and NOT United States, but both are checked still).
If MexicoToolStripMenuItem.CheckState = CheckState.Checked Then
UnitedStatesToolStripMenuItem.CheckState=CheckState.Unchecked...
End IF

I was just wondering weather it was possible to make it so that if I press the first a item on listbox1 then the first item on listbox 2 is selected aswell. For example I would like to have 2 listboxes lst1 and lst2 and I would like it so that when I select the first item on lst 1 then the first item on lst2 is automatically selected and when I select the 3rd item on lst1 then the 3rd item on lst2 is also selected.

I am working on a project for software engineering where we are trying to create a warehouse inventory system. I have created an inventory page where I can add/delete/search for an item as well as access invoices and reorder items... i am struggling on the delete item part. I have my design set up where there are four different lists on my page. One for name, one for serial number, one for RFID number and one for amount in stock. I want to be able to select an item by name and its information in serial number, rfid, and amount also select and have no idea how to go about this..I wanted to use four different lists because I need to be able to delete an item from the list and it remove just one from that stock and not the entire item unless there is only one of that item left in stock.

I have been trying to understand how to make thumbnails that I create from a directory, and place in a flow layout panel, selectable. That is, when someone klicks one of the thumbnails that thumbnail should be selected and, either automatically or by the click of a button, a new window (picture viewer) opens and shows the original picture. This is probably very easy to implement, but I am at a loss for the moment.I've tried to find an answer to this by searching the forums, but nothing good has been found so far.
[Code]...
The above code works perfectly and creates thumbnails from the directory c: emp and whatever subdirectory the user writes in the textbox (textbox2). No problem here, it is how to proceed to the next level that has got me stumped. As stated I want the user to be able to select one of the thumnails to get a better look at it in another window. So in selecting it, the procedure should get the path to the original image, and the rest is magic.

Using Webbrowser, I've managed to automate PDF downloads for several of the websites used by our company. I'm still a beginner at this process.Many of our PDF downloads, however, are from a Wells Fargo service called Wholesale Lockbox Image. The problem is that this Wells Fargo site expects the user to select items from a treeview as part of his query criteria. I don't know how to make Webbrowser select these treeview nodes programmatically.
Although I don't know anything about Java, the treeview is definitely a Java control. I know this for several reasons.(1) The instructions on the website specifically state that the the treeview won't draw until Java is installed.
(2) A standard Java splashcreen appears in the little treeview pane until the treeview actually begins to draw. The HTML code has an <OBJECT> tag which includes this attribute: ARCHIVE = "JWLTreeView2.jar"
Using Microsoft's mshtml library, I've tried looping through the elements on the page but can't find anything corresponding to the nodes in the treeview. I've also tried applying EnumChildWindows to the IE window, but here too I found nothing specific to the nodes. When I hover Spy++ over the treeview pane, it only identifies the pane as a whole, not the individual nodes.Furthermore, even when I select the nodes using my mouse, I don't seem to detect any corresponding alteration of the Webbrowser's HTML document (unless I overlooked it somehow).Does anyone have any suggestions on how to make Webbrowser select the treeview nodes programmatically?Oddly, I noticed that if the user saves the webbpage to his harddrive and then loads it into his browser from there, he can still see the treeview and select items (even without logging in to Wells Fargo), although if I bring the page home, the treeview is gone. I guess this means that IE is storing/caching the java file somewhere on the company machine, although I don't know if this fact would help solve my problem...

I know that the web's full of Q's and A's about how to use IsPostBack when selecting the value of a listbox.I have a stored procedure that returns a few values, and I want in runtime to have all the values be selected in the listbox.But when I loop through the SqlDataReader and do: listbox. Selected Value = reader(0), the final result on the browser is that only the last value gets selected.The listbox's SelectionMode is "Multiple".

I have two menu items from which I choose the interface language of a program (English or French).I want either of them to be chosen, both can not be chosen at the same time. I went over the properties of ToolStripMenuItem object and saw three properties that are confusing (Checked, CheckState and CheckOnClick), how can I mix them so that I get that functionality, I mean that when I check the French, the English gets unchecked and vice versa.

I'm trying to remove all the checked items in my CheckedListBox. I started by doing
CheckedListBox1.Items.Remove(CheckedListbox1.CheckedItems)
That seemed like it would work, but it didn't. I soon discovered that CheckedListBox1.Items.Remove only works on the the strings of the individual items.
