I'm looking to design a windows form application. My idea for the interface is to have a tree view on the left of my form as a menu structure to navigate between functions and the rest of the form to display the different 'screens'.
Basically what I'm imagining is something that resembles a deck - a vertical stack of screens where only one is visible at a time, similar to a TabControl but without the actual tabs.
My first attempt involved using Panels, but I couldn't switch between the panels in the design view.
Is this sort of functionality possible? if so, any ideas would be greatly appreciated.

Extend a TabControl. Call it say CustomTabControl. The idea is to remove the tabs. So, you get the functionality you want. There are many articles here on how to have custom tab controls. You basically need to tweak following properties.
ItemSize = (0, 1)
SizeMode = TabSizeMode.Fixed
Appearance = TabAppearance.Buttons

That seems to do what I wanted. Thanks!

In my searching I also found a PanelManager created by Mick Doherty:

It works similarly, but provides easer navigation between panels.

I think this is a windows forms. The article corresponds only to ASP.Net.

What would be the most practical Regex pattern for a whole-word-only search?
Example: Match "life" but not "life's"

Okay, never mind. NOW I know what the ExplicitCapture option does.

Regards

You should have found out what SMS stands for first and how it works, Short Message Service. The message limit is 160 characters by specification. You'll have to break up longer messages into multiple 160 character limit messages.

can you plz guide me how can i break up message and send it
when i breakup message will reciever get it in one message or in multiple messages?

You've got to be kidding me?? You mean to tell me that you don't have the skill to get the Length of a string (your message) and how to grab SubStrings of 160 characters in length? If you can't do this, then I highly suggest picking up a beginners book on C# and working through it before you attempt to write another application. This is very basic "Strings 101" stuff you're asking about.

You have no control over how the reciever recombines, or more acurately, does NOT recombine them. You cannot force the reciever to put the message back the way you want it. They will get each as a seperate message and there is nothing you can do about it. Thatose are the limitations you chose to tolerate when you chose to use SMS as a communication medium.

Maybe, but maybe not:
In the cellular phone industry, mobile phones and their networks sometimes support concatenated short message service (or concatenated SMS)
|
|
|

You can download the technical specification here[^] (registration required)
You want to look for PDU mode SMS. Note that concatenated SMS is quite a complex subject ( because the order of delivery of sms messages is not guaranteed, enough information must be included to allow message re-assembly on the receiving side. Your ability to send concatenated SMS will depend on
- the library you use for sending messages (don't know the ones you mention)
- the ability of the phone on the other end to decode concatenated SMS (most phones do it nowadays)
If you want to read up on it before embarking on an adventure, have a read here[^].

I have a datatable that acts as a DataSource for control. Programmatically I am also deleting some rows from this table using code like
foreach (DataRow row in myDataTable.Rows)
{
if (row["Id"].ToString().CompareTo(myControl.SelectedValue.ToString()) == 0)
{
row.Delete();
break;
}
}
I am not calling AcceptChanges on datatable. However after this delete, I don’t see any rows that have a status DataViewRowState.Deleted
Any ideas what I may be missing?

I have this test code where I can see the same behavior. Can someone point what am I doing wrong here?
static void Main(string[] args)
{
DataTable table = new DataTable();
DataColumn col = new DataColumn("ID", System.Type.GetType("System.Int32"));
table.Columns.Add(col);
for (int i = 0; i < 10; i++)
{
DataRow row = table.NewRow();
row["ID"] = i;
table.Rows.Add(row);
}
Console.WriteLine(table.Rows.Count);
for (int i = 0; i < table.Rows.Count;i++ )
{
if (Convert.ToInt32(table.Rows[i]["ID"]) == 4)
{
table.Rows[i].Delete();
break;
}
}
Console.WriteLine(table.Rows.Count);
DataTable deletedRows = table.GetChanges(DataRowState.Deleted); // This returns NULL, shouldn't it have one row here???
for (int i = 0; i < deletedRows.Rows.Count; i++)
{
Console.WriteLine("Deleted: " + deletedRows.Rows[i]["ID",DataRowVersion.Original].ToString());
}
}

Got it, was missing AcceptChanges()
|
|
|

When you delete rows using DataRow.Delete() method, they're immediately deleted from the DataTable. What DataTable.AcceptChanges() does is to propagate back the changes to the original data source of the DataTable (e.g., an SQL Server database)

One option would be using the PowerShell[^]. You could also query WMI[^] for Win32_LoggedOnUser. You could also opt to write a small daemon that sends a small message containing the Environment.UserName to the server.
