Thanks a lot Mr. for ur valuable reply

Dim Buffer(256) as byte
if(cnt=128)
spi.write(buffer)
System.Threading.Thread.Sleep(1)
EndIf
i have made like this,in this it is making the program execution delay,but i want to stop the spi writing for 15 ms,after 15 ms delay it should write data.
please provide me the solution to delay spi communication asap
thanks in advance

i need to insert delay between spi.write().means i will send 128 bytes of dataat the first,then i want to insert a delay of 15ms before sending next 128 bytes.
i am doing like this
Dim Buffer(256) as byte
if(cnt=128)
spi.write(buffer)
EndIf
after every 128 bytes i want to delay the writing by 15ms
how to acheive it

Hi OG,
please provide me some related examples,this username property made me little confusing,"don't think it as hand it to you on a plate",just share the things u know.related examples may help me

Yes ralf I agree with u,this is the UI only,i want the user entered data to be stored and restored while opening the form.how to do that is confusing me,if u have any example share with me

please can u explain in detail how to do that for combo box,listbox and text box.
In form 1 I have did this
private void bCRTToolStripMenuItem_Click(object sender, EventArgs e)
{
Form4 F4 = new Form4();
F4.Show();
}

on pressing bCRTToolStripMenuItem button Form 4 will be displayed.
in form4 I have a combo box and text box and listbox.
on a click of button I will add value to combo box.(before that while creating form 4 .I have added 4 default values to combo box using the collections properties) .after adding the new value for combobox I will press ok button.the ok button code is this.close();but when I reopen the form on clicking the button on form1.the newly added values doesnot reflect in the combobox list.so I need how to save that values.
here is add new item to combo box button code.
private void button1_Click(object sender, EventArgs e)
{


i = i + 1;

comboBox1.SelectedIndex = comboBox1.Items.Add("Message" + i);
F5.listBox1.Items.Add("Message" + i);

F5.Show();

if (comboBox2.SelectedIndex == 0)
{
comboBox7.SelectedIndex = 1;
comboBox8.SelectedIndex = 0;
comboBox9.SelectedIndex = 0;
radioButton4.Enabled = false;
textBox3.Enabled = false;
}

}
as I am new to c# and visual studio ,kindly help me to come out of it
Thanks in advance
