I have 9 small PictureBoxes that all have the same ContextMenuStrips. I need to be able to change the Backcolor property of the PictureBoxes via a ColorDialog. How would I determine which PictureBox has been selected so I can apply the correct PictureBox with the chosen color?

I am trying to build a context menu for a little "random quote" generator project. Most of the context menu for the NotifyIcon I can create at design time, but I need to create a submenu of file names that the user can choose (check) to be included in the quote population.
I originally did this in VB6 and it worked, now I get a Null reference error. The problem occurs in the Sub BuildChooseFilesMenuItems. Code follows. (Basically, I need to read in the filenames, make them menuitems and keep track of their "checked" state. It is dynamic because the user could add new quote files to the directoryy where they are stored.

I have a context menu strip associated with a listview. Everything work just fine however one of my menu options on the context menu strip has a pop-out menu (you know, you hover over the selection, and another menu strip expands out).I can seem to get these to work correctly.
Public Sub ReleasedToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ReleasedToolStripMenuItem.Click
FileEntries(ListViewSelectedIndex).Status = "Released"

So I changed my sub to read as the one VB created, and still didnt work. So I went back to edit the context menu, double clicked "Reserved" menu items, then VB creates a sub w/o the _1 (like I had before).Also the check-box status for these menu items works fine.
I got 3 listboxes.

I'm trying to add multiple items to a list box from a database but I'm having a few problems getting it to work. Below is the code i have so far but for some reason it will only add the last field in the database to the listbox and not the remaining 12.

I have a listbox that gets populated with files paths based on search terms provided by the user. I want the user to be able to select multiple items on the listbox, and then be able to export the files listed to another folder. See the attached image for what I'm talking about.
The problem I'm having is that I don't know how to take the items selected and turn them into a string array. Everything else I can figure out, but this one has me stumped.

I'm using VB.NET 2008. I have a form with about 10 or so labels on it, and that could increase the more I develop my assignment. I would like to give each of these labels a context menu, which says "Whats this?" and provide a message box to the user with the appropriate help text. Now what I've done so far is created a contextmenustrip on my forum, and linked all the labels to that single contextmenustrip. I have also added a menu item to that strip called WhatsThisToolStrip MenuItem, but I am at a loss, on where to go next, and find out on what label the contextmenu was activated on?
So for example if a user right clicks the lblStatus label and selects "Whats this?" item a different message box will appear than if the user right clicked the lblSid label.
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)?

View 3 RepliesI have not programmed since the late 90's (VB 6.0)Using Visual Basic 2008 Express, I'm creating a simple program but have one question:Is there a quick way to change a value on multiple items? For my program, I need to make a group of text boxes (anywhere from 14 to 546 unique boxes) "Enabled = True" or "Enabled = False" depending on a user selected value.
In a little more detail: The user selects the number of data rows on one tab. On the other tab are 40 rows of text boxes (14 boxes per row). If the user selected 15 rows, every row below 15 should be "Enabled = False".Thus far, I've coded a bunch of if-thens that run each time the user changes the selected rows (a line for each text box that makes it enabled or not). There are then 40 if-thens with lots of code in each.
I am sure there is an easier way to accomplish my goal without using hundreds of lined-up text boxes.

I would like to disable a specific items from DropDownList. I have below code but it does not working. DropDownList have 5 items.And,I'm getting error:Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Dim X As Integer = 0 <> 1
DropDownList1.Items(X).Enabled = False
End Sub
But, if I add a different value for X, then it disable 1st and 2nd item.
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged

DropDownList1.Items(X).Enabled = False
End Sub
My goal is if I would have a 365 items in DropwDownList to disable items for example between 120 and 150.
I am creating a web application in ASP.net/VB.NET and I have an issue with the gridview.Currently, I have the gridview populated with data from the DB and I've also coded the update button to allow the user edit any necessary information through a form that pops up.[URL]...
What I'd like to do, if possible, is add a button to the two right columns(I already put one in the Dock Out Time column) which will be invisible if the column is set or will set the current time to the column. Setting the time for those two columns is already handled through the update form, but my supervisor asked me to try and see if this was possible.
Those two Time columns are Templatefields(since I format the display time from what is actually in the DB) and I added an asp button in the ItemTemplate for that Set Button in the picture.Is this even possible to do and if so, how would I access this button in the code behind so I can add functionality(setting the time and hiding it if the column is not null)If it's not really possible to have two items like this in a templatefield I can just make 2 extra columns for these buttons but I think this would look much cleaner.

I have some items in my listbox which I will store everyone of them into my database, what I am doing now is looping the box and call my database saving logic to save every single item. I thought this is pretty inefficient, is there anyway that I can use to batch save my items so that I don't open and close the connection as many times as my items.
For Each item In outletToBox.Items
.CamCode = Items.ToString
.CamCampaignAutoID = retID
.CamRemarks = uitxtCamRemarks.Text.Trim
