in the textbox when i run the program.I want that it calculates the value of two textbox n shows the result in third textbox.

TextBox3.Text = result.ToString();
|

this is same as,
int result = int.Parse(TextBox1.Text) * int.Parse(TextBox2.Text);
TextBox3.Text = result.ToString();
|
|
|
|
|
So what is happening? Is an exception being thrown?
|
|
|
|
|
Did you try to debug it.Is it value is properly assigned to the textbox.Any error or exception?
|
|
|
|
|
There is nothing wrong with this code. Problem seems with your execution ? Where are you executing these ? Any thing here is runtime created ?
|
|

I want to assign a integer value to a textbox during runtime.
plz help m new to asp.net.the code i have written does not shows
the value in textbox during runtime....:
int Total = (Convert.ToInt32(Txtproductprice.Text) * Convert.ToInt32(Txtproductquantity.Text));
//string total = Convert.ToString(Total);
Txttotalprice.Text = Total.ToString();
thank's

//string total = Convert.ToString(Total);
Txttotalprice.Text = Total.ToString();
int result = int.Parse(TextBox1.Text) * int.Parse(TextBox2.Text);
TextBox3.Text = result.ToString();
|

It may also be worth while looking at TryParse to make sure the text boxes contain valid numbers.
|
|
|
|
|
Do you reset control values before assign value to TextBox?
Txttotalprice.Text =Convert.ToString(Convert.ToInt32(Txtproductprice.Text) *Convert.ToInt32(Txtproductquantity.Text));

What have you tried so far? A simple Google search would have gave you a nice idea.
void mygridview_RowCommand(Object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = ContactsGridView.Rows[index];
}

I have to develop an application, which can able to connect to a GPS device which is connected to serial port in our system and also able to read all the data from the device.
Currently I am able to make connection to my system's serial port but not able to connect to that GPS device and also not able to read the data from the device.
So in brief problem is that, "how we read the device which is connected to our system's serial port."
Please help me out to solve this problem.

Are you trying to build a web application that connects to the serial port of the clients PC? You won't be able to do that with ASP.net.

I am able to connect to serial port but not able to read the data from the connected device. Here is the code which i am using to read the device-
// Create the serial port with basic settings
SerialPort port = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);
port.Handshake = System.IO.Ports.Handshake.None;
port.ReadTimeout = 5000;
port.Open();
//retrieve number of bytes in the buffer
int bytes = port.BytesToRead;
//create a byte array to hold the awaiting data
byte[] comBuffer = new byte[bytes];
//read the data and store it
port.Read(comBuffer, 0, bytes);
string str;
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
str = enc.GetString(comBuffer);
txtData.Text = str;
port.Close();
when i am running this code then I get 0 in BytesToRead and comBuffer.
I think i am doing something wrong but what it is not have any idea.
