VS 2010 Add Handler To Toolstripmenuitems That Have No Dropdown Items?
Oct 25, 2009
I'm making a program that uses recursion to transform the nodes in a treeview to the items in a contextmenustrip. The nodes will have tags within them that when I add a handler to the menuitem, it will run through a script from the tag to tell the program what to do, the only problem is that I don't need a tag or an even handler for any of the menuitems that have dropdown items. How could I do this?

I have multiple combox boxes,
A B C
Combobox B has items Fruit, Veg, Dairy
Combobox C needs to contain 3 list and depending on what value is selected in Combo Box B.
For example,
If I select Veg in Combo Box B, I would like to have a drop down list containing "tomatoes, lettuce, onion,..........."
If I select Dairy in Combo Box B, I would like to have a drop down list containing "Milk, Cheese...................."

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 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.

Option Strict Off
Option Explicit On

how to add further items to a dropdown control on the ribbon.
So far I have been able to create a number of items manually and then afterwards change the label of these items using
Globals.Ribbons.Ribbon1.DropDown1.Items(i).Label
Furthermore I found that some recommend using this to add further items to the dropdown control. But I am having a hard time trying to understand how to use it.
Globals.Factory.GetRibbonFactory.CreateRibbonComboBox.Items.Add
I would like to see a sample of how others have done it.

In my VB.NET (desktop) application I'm adding items to a dropdown box like this:
Me.mnuSetup.DropDownItems.AddRange(New System.Windows.Forms.ToolStripItem() {Me.mnuAddUser, Me.mnuDeleteUser, Me.mnuChangePassword, Me.mnuClearLog, Me.ToolStripMenuItemClearStatusWindow, Me.mnuSep1, Me.mnuRefreshFileTypes, Me.mnuOptions, Me.TestHTTPSUploadToolStripMenuItem})
I only want the Me.TestHTTPSUploadToolStripMenuItem to be added if a boolean is true. How would you put an if condition inside this AddRange method?

Is it possible to control the height/number of items shown in a select dropdown box? Or do I need to code a custom widget? Is this possible?
Forgot to mention I'm using the following code:
<asp:DropDownList runat="server" Width="288px" CssClass="Select"></asp:DropDownList>

I have my program set up to read the contents of a Directory, and then populate a drop down menu with the names of the files in the directory. (I am using the MenuStrip). Inside my program, it is also set up to create a new file in that directory, and I wish to add this item to the dropdown menu upon creation. The list is entirely created and populated from the code, and the contents of the list depend entirely on what's in the directory.
I have tried using MenuStrip.Items.Remove(menuItem1). Now, when this command gets executed, it does remove the top level Menu, however when I go to repopulate the menu, I end up with duplicates of my files listed in the drop down. I am stuck with how to clear these out as well?

The dropdown box displays all the items previously added to that column.
I want the user to be able to enter a new value OR just pick a previous value from the dropdown list. (This is when inserting a new row)
Problem:
Whenever I enter a value, it jumps around in my table like its on acid or something. Whenever I select a value from the list, it takes me to the line in which the value was originally entered.
How do I get it to do what I want.

I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]

When changing properties of a ToolStripMenuItem at run-time, the changes are not reflected visually. If I check the values of the property that was changed, it shows the new value, but it will not show on screen. I have tried changing the Text value and it doesn't show the new text. I have changed the Checked value but it doesn't show as checked. I have even added event handlers, but they do not trigger.

I'm trying to use a split button from a tool strip to add and remove selected items in a listview.Users click the button to add the selected item which appears in the split button drop down menu as checked.The drop down menu has three items at any one time, each with a default value of <none> - this is replaced with the text from the listview when an item is added.When users click the item from the drop down, the item is unchecked and the text returns to <none>.
The drop down should populate from the top down so if a user removes item 1 or 2, the items below would appear to be moved up with the 3rd item now showing <none>.

I am trying to create a ContextMenuStrip where I add a certain amount of ToolStripMenuItems based on how many columns are in a DataGridView via code. I am wondering, since I am creating all these ToolStripMenuItems in code, how would I handle the "CheckStateChanged" event on all of them separately? Or how can I figure out which one of those ToolStripMenuItems was clicked?
Here's a code example of what I mean:
Private Sub CreateCMS()
Dim CMS As New ContextMenuStrip
Dim TMS_Main As New ToolStripMenuItem

The form is a dialog, with KeyPreview = True and AcceptButton = (none)Handling Me.KeyDown, and Me.KeyPress do not trigger when I press either the Up, Down, or Enter buttons. Me.KeyUp will fire on up and down, but not enter.I put a breakpoint on the procedure declaration and the first line of the procedure (the Me.KeyPress and Me.KeyDown event handler procedures), and they never fire.

I've been fiddling with this for ages and can't get it right. If you have this in C#:
videoSource1.NewFrame +=new NewFrameEventHandler(videoSource1_NewFrame);
void videoSource1_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
// stuff to do in here
}
How would write it in VB? My head is spinning with AddHandler and AddressOf and I can't seem to get it right.
