I created a Class that inherits List(Of TKey, TValue) and adds a few functions. Its purpose is not to add items to it at runtime, but when it is initialized. I would actually like to remove the add/delete methods from the class (as it currently exposes them from the inherited class).

View 7 RepliesI have the following on my interface / webform: <div id="mydiv" class="forceHeight" runat="server" />
now I have a dondition in my code behind where if a certain situation is true I need to remove the forceHeight class from this control. I know in C# you can use:
mydiv.CssClass.Replace("forceHeight", ""); I'm not so sure how you do this using VB? Intellisense doesn't offer me this option?
I'm trying to get a ComboBox to remove the 6th string in the ComboBox or an index of (5) but it doesn't remove it here is the function I am using:
if ComboBox1.items.count = 6 then
ComboBox1.Items.RemoveAt(5)
End If
why the code...
Form1.Controls.Remove(myCustomControl) ...does not remove the control.
Because whenever I remove a control and add it again, it does not Load but rather just changes its visibility from false to true and all the variables are not reloaded.
I tried to use .Dispose() but VB.net tells me thatit can't access a disposed object whenever I try to add the control again.

View 6 RepliesI am in the process of prototyping a small sockets application, which monitors IT infrastructure (due to in-house financial and deployment restrictions, I am unable to utilise an existing commercial or open-source solution). Basically, I have a server application and associated agent process for communicating heart-beat data to the server. The server application implements a TCP socket class (TCPDevice), which is called from a WinForm. I am aware of the restriction on updating the UI from processes running on separate threads, and that the preferred technique for acheiving this is via the use of Delegates in conjunction with the Invoke method. Having had very little need previously for using Delegates (apart from of course std windows events and the BackGroundWorker control), I am at a loss as to how to do this in the context of my application, and would appreciate some assistance, although it has occurred to me that I could use the backgroundworker for marshalling updates to the UI.
Eventually the application will need to update a grid of devices via feeds from the defined agents, however for the purpose of this exercise simply updating a status bar on the UI will suffice. The section of the code which I believe is relevant to propogating the code to the form is contained in the OnDataReceived method.Below is a code excerpt from the protoype app which should put the above into appropriate context:
Code from the form:

View 1 RepliesSuppose I have a DataGridView called gridFiles.
For Each row as DataGridView in gridFiles.Rows
MsgBox(row.Cells("somekey").Value.ToString)
gridFiles.Rows.Remove(row)
Next
I will see message boxes, but only for every other row. What I think is happening is that the internal pointer for gridFiles.Rows gets off, because there is 1-fewer rows on the next iteration.
I have a DataGridView with 7 cells, in every cell I'm into if i press escape the current row is removed thou an event i made named Public Event EscapeOnFirstRowPressed with no problem, and brings me the control to each initial state. The general idea of this process is when all the cells are fulfilled then

View 2 RepliesI ma using DevExpress controls (which doesnt matter for this example). I have a lookupEdit control and I never want the EditValue_Changed event to fire. Can I use RemoveHandler to do this? If so can someone give me a code example of doing this? Should I put RemoveHandler in the load event of the user control I am creating? Or does it go in the EditValue_Changed event of the lookupControl?
