Forms :: Tabcontrol1.tabpages.remove Not Working In A Particular Event)?
Jun 15, 2010
I have an event called "worksheet_selectionchanged" which occurs when a range/cell is selected in an excle file.When the event is triggered, all the tabpages in a tabcontrol should be removed.The code is given below:
Private Sub myWorksheet_SelectionChange(ByVal Target As Excel.Range) Handles myWorksheet.SelectionChange
for each tabpagesToRemove as TabPage in tabcontrol1.tabpages
tabcontrol1.tabpages.remove(tabpagesToRemove)
[code]....
but when ever i select a cell in the excel file, the tabpages seems to be "not removed".

I am creating an application which has n numbers of tabpages in three different tabcontrols. some of the tabpages are having graphs and rest of them are having some other calculations based on the data of focused graph tabpage.What i want is when user selects different tabpage containing graph the data of the graph tab should be passed to all the other tabpages using the data to calucate. There is one way which i get is to loop inside all the tabpages,but i want to raise an event from the graph page and handle the event in all the rest of the calculation pages.

I build my first Project composed of several forms and it�s working just fine. Id like now to redesign the project as a MDI Application. Once created the parent form, I can create child forms but thats not what I need. What I would need is convert my already designed and working forms to MDI child forms. How can that be done?

I'm creating a system in VB.net that utilizes Lua via the LuaInterface.
To associate an event in Lua with a function, I can simply do this:
RegisterEvent("tick", function(nt)
if not lcc then return end
if nt>=tt then
[Code]....
how I should change my RegisterEvent Function/Sub and how I should make the DisconnectEvent.
I know this is kind of annoying to try and understand what I'm trying to say. Feel free to post a comment asking for clarification. I'll be more than willing to try and explain it to the best of my abilities. If the LuaInterface has some kind of native way of handling this, I'm open to that as well :)

My application uses several checkedlistbox controls, datagridviews, and textboxes.I'm using the checked list box to provide a more intuitive interface for the users -- they know what they selected by the check mark.I have a binding source for all the individual textboxes (they are in one table) and a binding source for the datagridviews.I use the insertonsubmit and deleteonsubmit for changes made in the listboxes.I can then use the getchangeset to determine if any changes were made to the record.My problem is that sometimes a user only wants to "test" inputs to a record but may not want to have those changes actually made to the database -- or an error was made and they want to "undo" the inputs.How do I remove the unwanted changes and allow the user to continue working with the original data?

Problem: I have a document class which contains a list of objects. These objects raise events such as SolutionExpired, DisplayExpired etc. The document needs to respond to this.
Documents can sometimes exchange objects, but a single object should never be 'part' of more than one document.
My document class contains a bunch of methods which serve as event handlers. Whenever an object enters the document, I use AddHandler to set up the events, and whenever an object is removed from the document I use RemoveHandler to undo the damage. However, there are cases where it's difficult to make sure all the steps are properly taken and I might thus end up with rogue event handlers.

I'm writing a small 2D engine that uses Lua to control it. I've been setting events up in between the Lua and the VB.net for the past little while here. The problem, I've realized, is that is that I can't seem to remove the events which is screwing up quite a few things (because they are being called when they should be done with). To fix this, I wanted to add some kind of way to remove the specific event handler.
I know how to add an event handler:AddHandler Button1.Click, AddressOf Button1Clicked
But with this in mind, is their a way to remove a specific event handler in the VB.net? I didn't explain this very well: If I have this:

I have a Timers.Timer called COMTimeout, to which I add an event handler using:
AddHandler COMTimeout.Elapsed, AddressOf TimeoutEvent
however, the handler may also be:
AddHandler COMTimeout.Elapsed, AddressOf SecondTimeoutEvent
I now need to remove the handler, is there a way to do it without knowing the name or do I need to keep track of which handler as been assigned?
