the problem is u always create new instance of database connection in your background thread, i mean you always call this code in your backgroundworker:
MySqlConnection connection = new MySqlConnection(connectionString);
MySqlCommand command = connection.CreateCommand();
command.CommandText = yourSelectQuery;
MySqlDataAdapter adapter = new MySqlDataAdapter(command);
adapter.Fill(yourDataSet);
command.Dispose();
connection.Close();
connection.Dispose();
this database connection remains in pool event if you leave your background worker
i suggest you create static field, or property in your DataLayer that hold for your database connection. Fill with correct connection string. DataCommand keep created in background worker. Dispose that datacommand object and your adapter after fill your dataset object. that will only 1 database connection remains in your database pooling.
i hope this will help.

Yes, you need help on many aspects. First, pick a better subject line, instead of "I NEED HELP?". Secondly, clean up the grammar a bit. Thirdly, be a bit more clear about what you are having trouble with. Just saying the program is slow because of XML data doesn't help diagnose your program's problem very well.

Hi!
You'll have to p/invoke SendMessage to send TVM_SETINDENT to the TreeView.

Oh come on, calling SendMessage after looking up the message in MSDN is not rocket science.
The message definition can be found in CommCtrl.h in the Platform SDK Includes: TV_FIRST is 0x1100 and TVM_SETINDENT is TV_FIRST + 7.
The link to MSDN is here[^].
Just try it, it's really not that hard!
If you still have problems, come back here for help.

Hi.
I have the same problem, but I couldn't find the relation between calling SendMessage and increase/decrease the horizontal spacing between the nodes in a treeView??
I think , we have to change a property to set them !
Isn't it ?

Buy a book. Read my article on how to use google. Generally try to do a little research before spewing out all your questions here.
