|Hi there! there is a lot of difference between vb and vb.net.
Visually, there are a lot of windows that have been added to vb.net.
Code wise, vb.net now makes use of inheritance that is vb.net is now object oriented and makes use of all the capabilities of OOP.
The .Net framework is so complex that it contains a lot of tools that can be used for anything that vb 6.0 cannot do.
This is just but a few. (0)

I have a for loop with which i want to sum the bytes in a packet from the 3rd position to the 50th position (assuming that the number of bytes are 55).
So i have done the following;
dim i, sum as integer
for i = p2 to p50
It does not sum the bytes from p2 to p50 (where p is the position of the index such that p0 will be the first byte).
It just shows the sum as the value of p2.
Can anyone help please?

Is there a way of reading data from the socket. I mean if a socket has a packet of data, how can i read that packet's data to create appropriate files?
This is because, i am sending data from remote site, and i have an asynchronous server running. I can detect connections but cannot read the packets from the buffer. The packet's data section has details like time, id number, site number etc, which i need to extract and create files based on the site numbers and date / time as shown in the packet.
PLEASE GUIDE ME!!!

I want to insert data directly into my windows form data grid and load a combobox(userid) in the 1st column of data grid,a textbox(password) in 2nd column of datagrid.
The code for insert data is:

dim da as new oledbdataadapter
dim ds as new dataset
messagebox.show "Record Inserted successfully"
I want to insert the data into database so when the user presses the enter key in 2nd column of datagrid(txtcol2.text),the above code for inserting data is executed and cursor moves to second row of 1st column.
can anybody explain me how to achieve this in vb.net 2003 windows form?

|I have a question concerning the GC in VB and when to set an object to nothing to remove all references. If I have an instance variable that I declare and use it several times, pointing it to various objects in a given method, will this cause a problem with the garbage collector? Here is an example of what I mean:
Dim lvItem As System.Windows.Forms.ListViewItem
lvItem = lstView1.Items.Add("Item1")
lvItem = Nothing
lvItem = lstView2.Items.Add("Item2")
If my understanding of VB garbage collection is correct, the "lvItem = Nothing" should be required in order to dereference the object it is pointing to between each use. Is this correct?
