C Sharp :: Sum Of 2 Textboxes And Then Getting Total In Last Textbox
Oct 3, 2014
I am trying to get 2 numbers from 2 textboxs and get a return sum in the third textbox. the strange thing is that i got it to work with this code that i am going to provide on the last app i worked on, now on the new app i am on it doesnt work at all.. I am not getting any Errors, just shows a zero when i calculate to the sum of the total textbox.
int sum1 = 0;
int sum2 = 0;
int result = 0;
if (int.TryParse(txtPrice.Text, out sum1) & int.TryParse(txtQuantity.Text, out sum2))
result = sum1 * sum2;
txtSubTotal.Text = result.ToString();
So I've got a button that has to use 2 textboxes to search for 2 columns in my database.
private void btnFilter_Click(object sender, EventArgs e) { SQLiteDataAdapter adap = new SQLiteDataAdapter("select * from Test", GetConnection()); DataSet ds = new DataSet(); adap.Fill(ds); dgvTable.DataSource = ds.Tables[0];
[Code] ....
My Current code for it.
The GetConnection(); and the CloseConnection(); Methods are just making a new connection and closing that connection, if needed I can post that code too later.
But basically, It only "filters" 1 textbox but if I say I want to search the Channel and the Log in which it is in, it doesn't search anything and returns all data in the database.
In my application there is a structure that holds 200 parameters for 200 tests. These structure is converted to byte array . I want to write this byte array to a file in save button and when I click open button, this file must open and write these bytes to corresponding text boxes. How it possible.?
Every time the timer clicks it should show a text letter like (T) for tortoise and (H) for hare that moves around the board when the user hits go on the GUI.
I have an ms access database with 2 tables in it which I named Customers and Products. I am using visual studio 2010, in my windows form I have 4 textboxes and 3 button in it, for my 1st textbox when I entered one of my ProductCode such as 10111, then press the Display button, the other remaining 3 textboxes should populate and display the following;
i create two forms add a password in first form throgh user input and second form will open i want that password will automatically be added to second form. first form is ok working according to my expactations but problem that it does not enter pssword in second form i reference that textbox that is
stdfrm std=new std(); std.a=txtpwd;
it displays an error that cannot implicitly convert type system.windows.forms.textbox to string
I have a text box invoice no on windows form and i need to retrieve data from database and everytime user click on the add button the invoice no should increment by 1...
I have 3 columns already made Product, Price, Quantity, - what I want to do is take the textbox's txtName, txtPrice, txtQuantity, and add them to the columns in the right specific places.
I'm trying to get some more user friendly things in my program done. Now I'm trying to filter by typing in a text box and it filters to what you are typing and shows the entire row.
I am completely new to SQL server i know a few of the basics. I have a VS2010 asp.net c# application with two dropdown listboxes and a textbox. I need to calculate the numbers e.g 3 + 3 = Medium, using the table below to calculate the answer so i can insert the output value into a textbox.

I have a window form with datagridview,textbox,button and listbox. In datagridview i have added a column. In first row i have given the value like 7000,
second row 2500, third row 7000, fourth row 1000, fifth 1300, sixth 9000....n number of row:
if i enter 12000 in textbox1 then it will calculate the total in particular rows in datagridview.And the total should be less than 12000 what we have entered the value in textbox1.
The result will display in listbox..
like first greater value is 9000+2500=11500 , second greater value 7000+1000+1300=9500, other third greater value is 7,000.
So i have given a sample code where i cannot get the solution ..
double search; search = double.Parse(textBox1.Text); double sum = 0; for (int i = 0; i < dataGridView1.Rows.Count - 1; i++) { double se2 = Convert.ToDouble(dataGridView1.Rows[i].Cells[0].Value.ToString()); if (se2 == search) {
How you can touch a datagridview and it would insert the name it has for a product into a label or textbox.... As I have looked all over and I can't really find a proper way it is mentioned or maybe I am not applying it correctly.
I can not do transferring data to textboxes from database.
="c#">using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using MySql.Data.MySqlClient; namespace WindowsFormsApplication1{
I have an HTML5 form with a number of text boxes on it. I would like these textboxes populating with data retreived from an SQL database, using inline C#. I have a stored procedure that returns the data.
As it is known there are nine boxes and in each box we can put numbers 1-9 without repetition. I am trying to check a given filled Sudoku puzzle whether appropriate numbers are inserted in each of the nine boxes. For the time being I don't consider row repetition and column repetition. I wrote the code using loops and condition
I used 9*9 text-boxes. The names of the textboxes is sequential like for example for the first box txt11,txt12,txt13 txt14,txt15,txt16 txt17,txt18,txt19
Actually, I used also the controls id to access the text boxes, and each box is checking with the neighboring boxes for equality both in forward -> and backward <-

So here is the code
public void BoxCheck() { int start = 82, end = 74; int i, b, f; for (int p = 1; p <= 9; p++, start -= 9, end -= 9) { richTextBox1.AppendText("Box " + 1);
[Code] ....
This works pretty fine, but is is the right way to do it? it is efficient? Remember for a full checking I have to include row check and column check as well, this is just for checking within each of the 9 boxes in Sudoku.
