C# :: Server-side Validation For Deleting Orders In Progress
Apr 18, 2014
[URL]
According to my project instructions, I have to make a "validation on the delete button, that before a record can be deleted it will check to see if the count of "In-Progress" orders for that product is 0. If it is greater than zero, it should not allow this record to be deleted."
So far I have on the code behind page:
protected void btnDeleteProduct_Click(object sender, EventArgs e)
{
DataView dv = (DataView)SqlOrders.Select(DataSourceSelectArguments.Empty);
[Coe].....
The professor said I have to: "As for getting the count, check your notes and book, specifically looking at SQL and the Aggregate functions. There is a function we talked about in class called "Count(OrderID)" and set the where clause to check for the productID.

I know this question must have been asked before, but the problem that I am facing is that I am using a library PoDoFo to parse PDF files. It seems that it is only compatible with C++.
Now I want the application to be web-based. That is, the user uploads a PDF file on the server, the server parses it and the parsed content is then sent back to the user.
Is such a thing possible with C++, or maybe any good work-arounds? Or should I look at server-side scripting languages like PHP and their respective libraries?

I have problems relating the HTTP server request line validation into a c++ code, where the request line is defined as follows:
method SP request-target SP HTTP-version CRLF
and the server supports absolute-path [ "?" query ]
At the same time absolute-path must start with / and might optionally be followed by a ? followed by a query, which may not contain ".
Basically, method must be GET, request-line must begin with / , request-target cannot contain " ,HTTP version must be 1.1 (HTTP/1.1), and the absolute-path must contain the character .

Been trying to configure the GridView to display ony 4 rows of data at a time. I thought it wasn't working because I forgot to set AllowPaging to True, but after I did that, I just get the error of
The data source does not support server-side data paging.
Source Error:
Line 66: titlesGridView.DataBind(); // displays query results
Here is my Books.aspx.cs code:
// Fig. 29.11: Books.aspx.cs
// Code-behind file for the password-protected Books page.
using System;
using System.Data.Entity;
using System.Linq;
namespace Bug2Bug.ProtectedContent {
public partial class Books : System.Web.UI.Page {
[Code] ....
Am I missing anything or doing something wrong thats not causing it to page & only display 4 titles at a time?

We've only covered up to Functions and how to use reference variables inside the function parameter.
One of the hw problem that was assigned was to write a void function that takes three parameters( num1, num2, num3) by reference and sorts their values into ascending order, so that num1 has the lowest, num2 the middle value, and num3 the highest value. For example, if user enters: 14, -4, 8, then the output should look like this:
-4
8
14
I've completed the program with a bunch of if/ else if statements but I was wondering if there was a more efficient way to sort the numbers. Bear in mind, we've only covered materials up to functions so I can't use any other new techniques that we haven't cover yet. Here is my code:
// This program will take three int parameters by reference and sorts their value into ascending order
//so that num1 has the lowest value, num2 has the middle value, and num3 has the highest value
#include <iostream>
using namespace std;
// declare function with reference parameter that with sort numbers
void sortNum(int &, int &, int &);
int main ()
{

I wrote a program for class. It did its job, but I want to make it better. The program finds all of the Pythagorean triples between 1 and 100.
As you can see, the program will repeat the same Pythagorean triples but in different orders.
What I want to do is have the program repeat each Pythagorean triple once, regardless of whether the ordering is different. I have tried, but only came up with the solution to solving repetition that is consecutive. But the repetition for Pythagorean triples jump around.
I got stuck on how to eliminate jumping repetitions. I only know how to make it not repeat on consecutive entries.

E.g., Pythagorean triple (6, 8, 10) appears. Then two Pythagorean triples later, (8, 6, 10) appears.
I got stuck on how to eliminate jumping repetitions. I only know how to make it not repeat on consecutive entries.
I nested one for loop, in another for loop that is nested in another for loop. One for loop for each of the values in the triple. The most nested loop is for the c value in a^2 + b^2 = c^2, and has an if statement: if( ((a*a)+(b*) == (c*c) ) , and then the program prints the numbers.
#include <iostream>
#include <cmath>
using namespace std;
int main() {
unsigned int a, b, c;
char con;
cout << "This program finds the pythagorean triples between 1 and 200.

The tools Hal's sells are: Hammers: $10.99 Wrenches: $10.99 Levels: $19.99 Tape Measures: $4.99 Screwdrivers: $8.99
In order to make things easier in the long run you have decided to make a c++ program that takes in all the orders for each register and tallies them at the end of the day.
Write a c++ program that does the following:
Create a Register class that can store all of the receipts for the day and the totals for that register.
This class could have the following member functions:
Contructor(int) - Creates a number of receipts based on an integer that is passed into the constructor (this is the largest number of orders that the register can take). You may also be required to create additional variables to make the program work but that's up to you to determine.
void getorder() - Asks the user how many of each item they want an stores that in the first available receipt.
void returnreceipts() - This function returns the details of all the receipts and the total for the day.
Register operator+(const Register &right)- This is an overloaded addition operator. When two objects are added together an empty temporary register is created (with 0 receipts) and only the totals of both objects are added to it. The temporary register is returned by the function.
Register operator=(const Register &right)- This overloaded assignment operator copies only the totals from the Object on the right.
In the Main function I would like:
Create 3 Register Objects. The first two registers are the ones in the store and should be initialized to take 10 orders. The third is used at closing time and can be initialized with 0 receipts as it will only take in the totals from the other registers.
Run the getorder function for registers 1 and 2 twice.
Run returnreceipts for register 1 and register2.
Reg3=Reg1+Reg2;
Run returnreceipts for register 3.
[Code]...
this is what I have so far I'm trying to get the input part working first, so the user would be asked each item individual how many they want? this will happen for 2 users, then the next register will do the same?

On a right angled triangle, if the user inputs only ONE side length (not the hypotenuse) and only ONE angle, what code is required to work out the hypotenuse? I know how to work out the final side and the remaining angle once I have this.

I am working on a 2D side scroller game. Where a ball is moving continuously towards right . I used a camera to follow the ball as soon as ball reaches the center of screen. I created a horizontal line to look like the surface on which the ball is rolling.
line runs from x=0 to x=800 (i.e screen width)
NOTE: (0,0) coordinate is at top left corner of display.
Problem: My display is 800 x 400 . Camera follows the ball, but soon the ball crosses x=800 and starts moving in black background. I want that line surface to stay there instead of going out of bound.
Additionally! I generated obstacles from x=800 which also move out of bound along with my line.
What should be done here? This is just my first c++ game project, so i might be skipping things that can solve the issue.
[Update] these screenshots manage to show, what the real problem is: [URL]

Right after I close FIFO on the producer side, the app on the consumer side gets into an endless loop. select() returns that FIFO is ready to read. Below is the excerpt from the consumer code. The FIFO is opened "blocking" on both ends.
Code:
FifoClass fifo_r = FifoClass("/tmp/FIFO_READ");
int fdr = fifo_r.OpenR();// this->fd = open(name.c_str(), O_RDONLY , 0);
for(int i=0; ;i++) {
FD_ZERO(&rset);
FD_SET(fdr, &rset);

Is there a way to make a circular progress bar in WPF without using another library or NuGet Package?
Like a tutorial on how to make it from scratch?
Right now, I'm using the existing ProgressBar UserControl but it looks horrible especially after I change the Foreground color from Green to DarkBlue.

I am running a windows forms project. on the form there is a datagridview, a progress bar, a textbox and two 2 buttons.
The two buttons are used to navigate through the records(one for next record and the other for previous record) the textbox displays the record that is being currently viewed.
How can I link the progress with the database or in this case the datagridview and when the next button is pressed it increments and when the previous button is clicked it decrements and also the progress to be fully filled when the last record is reached ?

For a project I'm working on, I need to be able to download a file from an FTP server and store it to a predetermined location with a predetermined name. No user interaction should be needed. Because the file is rather large, and I need the main program to remain responsive, this is going to need a progress dialog.
I could write all this myself and use the MFC wininet wrappers (CInternetSession et al) to do the downloading, but... Explorer already has this, and IE has such a dialog also. It doesn't seem unreasonable to assume those dialogs are available via some API.
Is a "FTP download with dialog" available as a windows API, or do I really need to write all this myself ?
