I'm using System.Net.CookieContainer. I fetch an initial webpage which populates the container. I want to make a copy of this container to use in the future. Is there an easy way to do this in .NET? I'm still new to .NET.
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://www.google.com");
HttpWebResponse resp = null;
CookieContainer cc = new CookieContainer();
req.Proxy = null;

I am trying to get my datagridview to display more than one row of data.Every time I call the program it only writes the 1st line of data in the datagridview instead of adding it to a new row.I have been looking on the forums for hours but combined with my inexperience I can not understand it. The following code is in a loop and it reads an xml file each time.The goal is to put the xml data from each file into a new row in the table.Public Sub ReadData(ByVal filename As String, ByVal file As String)Try
DS.ReadXml(filename)
DS.Tables.Add("MyTable")
With DS.Tables("MyTable")

I was just writing a windows application that populates three comboboxes from the same datasource. My datasource is a datatable. The way i populate the comboboxes is by repeating the following code for each of the comboboxes:
'populate 1st combobox
cbx1.DataSource = table
cbx1.DisplayMember = "someColumn"
cbx1.ValueMember = "anotherColumn"
cbx1.SelectedIndex = Indx
[CODE]...
When the application is run, and I select an item from the dropdown list of, say, cbx1, my choice is reflected in cbx2 and cbx3 as well. I find this behaviour strange and will be grateful if anybody could explain what is going on here behind the scenes. On a side note, I've been able to circumvent this problem by modifying my code as shown below, but would still like to have an explanation for this seemingly strange behaviour.
'populate 1st combobox
Dim t1 as datatable = table.Copy
cbx1.DataSource = t1
cbx1.DisplayMember = "someColumn"
cbx1.ValueMember = "anotherColumn"
cbx1.SelectedIndex = Indx

I'm trying to write some code which parses data and then populates a listbox. I'm using the IPWorks IPPort component which basically does the reading of port 30003. The ipport1_OnDataIn event is where all the action is. I parse the data, which works great.. however when I try and do something simple such as add text to a listbox, I get the dreaded error "Cross-thread operation not valid: Control 'lstListBox1' accessed from a thread other than the thread it was created on".I've googled the error and tried copy and pasting some workarounds but nothing seems to fix the issue.
If anyone can offer help, it would be greatly appreciated. If you could possibly show the code already implemented into mine, it would be even better so I can see how it works. It would make more sense to me. My code is below. The part i'm trying to get working is the lstlistbox1.items.add("Test") in Case "2". This is to just get it working.. I'll be adding listbox items in the other cases as well, and they'll be parsed values instead of "Test". This is just to simplify things at the moment.

I am developing a program that populates a rich text box and from a click event on a listbox. The data that is being loaded into the rich text box is located in a richtextformat file located on the hard drive. I noticed that when I entered a URL into one of the richtextformat files that it appeared that I was able to click on the text as if it were a link. So I wondered if it was possiable to click on that URL and open a web browser from the loaded richtextformat file? I have read several articles in regards to opening hyperlinks in rich text boxes which can open a web browser with a given URL.
View 1 RepliesI am creating a reporting app that pulls information off of a Sql database and populates the data in a datagridview control (DVG). I am using tab pages (Tabcontrol), and I have about 10 tabs with within the control. What I have done is created a dynamic control that will populate in each tab page once the tab is selected. I am using a split container and in my split container.panel 1 is where all my buttons and search functionality will be. In my split container.panel2 to is where the main DGV control will be. I have got this to function properly, however now I am unable to add anything to my split container.panel1. I would like to add diffrent labels and buttons in the panel1 one without putting another panel on top of the split container.panel1, and also if i do this when I resize my container the panel will just sit there. I am using the selected index changed event to get my split container to show in each of the diffrent tabs
Private Sub searchTab_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles searchTab.SelectedIndexChanged
searchTab.TabPages(searchTab.TabPages.IndexOf(searchTab.SelectedTab)).Controls.Add(splitContainer1)

I have a 'DataGrid' usercontrol on my simple little form and I press a button that opens a text file and populates the DataGrid like so,
A B C
1 2 3
3 4 4
3 1 3
Where A, B, and C are my column headers.
I also have a 'ListBox' on the form. What I would like to do is, allow the user to select one, two, or three rows (or all) in the datagrid, and press a button that will move the data from selected rows into my listbox (each row its own string in the list box).
I can populate the datagrib easy enough, but don't know how to access the cell data individually?

But how can i fetch data when the grid view is not in editing mode that is in ItemTemplate. I have tried the following-

But its getting the exception object reference is not set to an instance of object. This is probably happening because the above code should be used in a method like RowDataBound when a row is instantiated. But I have to fetch data from some other method.Again for clarification I want to fetch data when the gridview columns are in ItemTemplate Mode.
