t's not hard, it's easy - once you learn how to do it.
Just to add to what Richard gave you, the whole code is along the lines of:
using (SqlConnection con = new SqlConnection(strConnect))
using (SqlCommand cmd = new SqlCommand("SELECT Age, Description FROM myTable WHERE ID = @ID", con))
using (SqlDataReader reader = cmd.ExecuteReader())
int age = (int) reader["Age"];
string desc = (string) reader["Description"];
I have c# windows form application which displays the real time data from a board. I want to plot this data in a point graph in c#. Help me with this. I have given my code below which displays the data from board.
public partial class flow_click : Form
I am trying to plot the flow rate value(micro litres) and time(seconds) . so flow rate is my y axis and time is my x axis . whenever i click on button a new flow rate value is obtained which should to be updated on the graph
I have used all types of coding to remove the textbox but no use. I found few posts on Google search but the textboxes are associated with either a button control or checkbox control, using which, the deletion happens. I want the textbox to be deleted, if it is selected (meaning, the cursor is blinking in the text input area). I also tried setting textBox.Enabled=false; but no use as a statement textBox.Enabled=true; doesn't bring the textbox to life at all.
//if (virtTxtBox.BorderStyle == BorderStyle.FixedSingle)
//Determine the Index of the Button.
int index = int.Parse(TxtBox.Name.Split('_'));
label1.Text = index.ToString();
//Find the TextBox using Index and remove it.
TextBox txbx = (TextBox) pictureBox1.Controls.Find("txt_" + index, true);
label1.Text = txbx.Name;
pictureBox1.Controls.Remove(pictureBox1.Controls.Find("txt_" + index, true));
Hi, I said I experimented in various ways. Even after you commented about me using so many remove codes, i ensured they were not involved in the process and yet I could not achieve my objective of getting the textbox control(s) off my big picture box.
I searched online for 3 speech pronunciation libraries: "System.Speech.dll, Microsoft.Speech.dll and Interop.SpeechLib.dll". I want to know their time and origin, in which 3 libraries easy to use to write code ? Which library supports many countries' voices ? Which library is the most popular with programmers ? In the future, which 3 of the libraries will drop out ? et... ?
I found a speech pronunciation example that uses these libraries, I haven't found the source materials and the documentation for them, if someone who has programmed on this issue will answer it quickly, every time I don't know, thanks to you answers, I would say google search so what was the forum set up for ?
It was set up to answer specific technical questions; see How to get an answer to your question - C# Discussion Boards[^]. You are asking us to tell you which library of three is the best, which supports multiple languages, which may disappear in the future, etc. Apply the same question to any consumer product you care to think of and see why it is impossible to provide a definitive answer.
