I have a ContextMenu attached to a tray notifyIcon and I already have it on the form in design mode. If I look at it in design mode I can see evereything that I have on the main pop-up context menu. What I am trying to do is add to one of those choices programatically. Worked fine in VB6.I am reading in a list of filenames from a directory and want to place them as menu items in the 2nd level of the context menu.

I am in the process of converting VB6 applications to Dot Net. I am using VS2008 to do the conversion.I need to change some of the converted VB6 menus from MainMenu to ContextMenuStrip. Is there an easier way of doing this then recreating them?

View 2 RepliesI've done a lot of work to customize the template for ContextMenu in my app, and it worked great as a "right-click" popup window.To my enormous surprise, when I wanted to add the same ContextMenu to a button to work as a kind of "drop-down" menu, it reverted back to the default template. It is really, really, weird, considering it's the exact same control I'm using, and when I right-click the button the template is the one I customized, but when I left-click it(and open it with ContextMenu.IsOpen = True) it uses the default template? I'm pretty baffled right now, and hope that this isn't one of the (many) quirks with WPF that will require me to write hundreds of lines of XML code to fix something that shouldn't even be an issue in the first place.

I'm actually trying to help another member over at CG with this problem, on this thread url...And I'm clueless as to what to try anymore.The thing is, we're trying to add a Context Menu on a Menustrip. If you were to right click on any menu on the System's Start menu, you'd see, that you can right click any menu item, and do whatever with it.I have sourced some code, and eventually got a sample worked out - the problem is, it only works with top level menus, not submenus.[code]If you were to run this code, you'd see that only right clicking Testing ( the top menu ) works. Can anyone see any reason why this doesn't work with Submenu items

I'm wanting to add a menu to my project that is going to be dual controllable (touch screen and physical buttons). For when it is being used with only buttons, i need a way to 'scroll' through the items in a ContextMenu. I've tried using SendKeys to send up and down keys but this did nothing and i've also tried using 'GetNextItem' but this also did nothing.
View 1 RepliesI need to represent the following query using LINQ:
DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0
[code]....
Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.
Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)

I have been a programmer for 36 years (COBOL,FORTRAN, etc.) but I am new to VB.NET. I am writing a random quote generator program to teach myself VB.NET. On a context menu of a NotifyIcon I have some main menu items, one of which is "Choose random quote files". When I mouse over the main menu item the sub-menu opens. I can click on one of the filenames that has been loaded from a directory to include (or exclude) it from the population. As soon as I do, the context menu closes. I want the user to be able to click on more than one file name before the menu closes.
