C# :: Lookup Non-existent Rows In MySQL Table And Then Update Another Table
Dec 15, 2014I have written an SQL statement that would:
1) Count the number of rows in the table booking that are open and where the booking.postcode is "MK",
2) Take a note of the plot (in booking.plot_id), and then update the table plot.jobs with the value count.
For example running the SQL query when booking table has the following rows:
Would see the following highlighted values in plot.jobs being updated to 1:
I managed to resolve it with this code so far (note I am using Connector/Net):
public void RefreshPlot(){
string query =
"SELECT Count(*) AS count, plot_id FROM booking WHERE postcode='MK' AND status='open' GROUP BY plot_id";
var cmd = new MySqlCommand(query, _connection);
var da = new MySqlDataAdapter(cmd);
var dtCounts = new DataTable();
da.Fill(dtCounts);
[code]....
Currently, my code only checks for existing rows in the booking table and updates the plot table. However if the row gets deleted in the booking, then the changes are not reflected in the plot table.
Example: If we delete the row with plot.id=1 and plot.plot_id=4, then booking.plot_id should go back to being 0, if it was initially 1. At the moment, it doesn't. How would I update my SQL statement to better reflect this? In a sense, it should check for "non-existent" rows, i.e. the impact that the row plot.plot_id=4 & plot.id=1 has on booking.plot_id when deleted?

View 2 Replies View RelatedC# :: How To Start Application And Automatically Pass Input To That Application
May 9, 2012I want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?

Jun 9, 2014I am programming with the Code::Blocks IDE and using the GNU GCC compiler. When I create an simple console application that uses strings it kind of glitches out, but here's the code:

#include <string>
using namespace std;
int main()

What the output is:
Please enter a string of text: Hello World

C :: Gcc Compiler And Pointers
Mar 3, 2013The first sample program that I am reading on the book has the following code:
Code:
* Demonstrates basic pointer use. */

int var = 1;

Is this a compiler error or is there a proper syntax for pointers using the gcc compiler?
C++ :: Class Not Seen By Compiler?
Sep 18, 2014I have an issue. VS 2013 isn't recognizing objects that I've declared when I use class functions.I'm getting this error: "Line 14 and 15: Error C2228: left of '.asciiToFpc6' must have class/struct/union"...Here's the relevant code:
Source.cpp
#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include "fpc6.h"
[code].....
Additionally VS apparently doesn't like my bitwise operators in my class functions and doesn't think they're doing anything. It gives "warning C4552: ['|', '<<', '>>', '&'] : operator has no effect; expected operator with side-effect" for all of them, but it seems to me the code should work fine and actually accomplish things....
C++ :: Compiler Says There Is No Constructor But It Does Have One
May 29, 2013Code:
activity = new Idle(this, NULL);
class Idle : public Activity {
private:
float mTimeInIdle;
public:
Idle() : mTimeInIdle(0) { }
Idle(Objects *actor, Goods *target) : Activity(actor, target)

}
Error 1 error C2514: 'Idle' : class has no constructors d:jackydocumentsvisual studio 2010projectsperfectsimperfectsimperfectsimObjectsObjects.h 43 1 PerfectSim
The activity = new Idle(this, NULL) line is located inside the Objects::Objects(...) constructor.
Would it be caused by some cyclic dependencies? How do I go about resolving it?
C :: How To Implement Vectorization
May 20, 2013I'm trying to learn how to implement vectorization. Lets say I have this an array like this.
Code: int Array[10] = { 3,4,5,3,4,5,6,7,8,9};
If I traverse through the array and preform some simple calculation like adding numbers, how would I go about vectorizing this feat? For example if I want to add numbers, .
An example, add element at index 5,6,7 to element with index 1.
Code:
0 1 2 3 4 5 6 7 8 9 --- index
3,4,5,2,8,2,3,5,1,2 --- ints

C++ :: Compiler Not Recognizing Numbers
Sep 8, 2013I'm working on this homework assignment where the program takes in the user's height in inches, weight in pounds, and age, then calculates their hat size, jacket size and waist size. The formulas for these are as follows:
Hat: (weight/height) x 2.9
Jacket: (height x weight)/288 then adjusted by adding 1/8 an inch for every 10 years over the age of 30 (The adjustment only takes place after a full 10 years, so there is no adjustment for 30-39, but there is for 40)
Waist: (weight/5.7) then adjusted by adding 1/10 of an inch for each 2 years over the age of 28 (the adjustment only takes place after a full 2 years, so no adjustment for 29, but there is for 30, etc)
I'm supposed to utilize functions for each of the three formulas.
There's a couple things I can't figure out.
1. Why won't the compiler recognize 2.9 and 5.7 as numbers?
2. How do I adjust the calculation for the jacket and waist based on age?
Here's what I've got so far:
#include <cstdlib>
#include <iostream>
using namespace std;
double hatSize(int weight, int height);
double jacketSize(int weight, int height, int age);
double waistSize(int weight, int height, int age);

C++ :: Check If Compiler Has 11 Enabled?
Jan 28, 2012Is there a way to check if a compiler has c++11 enabled?
I have a library and it has converters between std strings and the internal string type. I current have preprocessor surrounding the converters for u8string, u16string, and u32strings, but it requires the end user flip the switch manually. It would be nice if I could know at compile time without being told whether or not those types exist.
C++ :: When Compiler Do Template Instantiation
May 2, 2014As we know in the compilation stage, the compiler will instantiate a concrete type for a template, for example:
template<class T> void test(T m ) {
cout << m << endl;
}
int main() {
int kl = 0;
test<int>(kl);
}
In the main function, the compiler will try to have a int entry. Also we know that in the compilation stage, generally we have several steps: lexical analysis, syntax analysis, grammer analysis and intermediate language(IR).
So my question is: In which step is the instantiation done? Before IR or after IR?

C :: How To Implement Two Dimensional Arrays
Feb 10, 2013Code:
char str[40][40];
int number = 7;
for (int i=0;i<number;i++){
printf("enter %d th string::",i+1);
scanf("%s",str[i]);
}
Above, I have a little snippet of a code that I'm trying to figure out. I don't really understand how to implement 2d arrays in C that well. But, I mostly want to know is how and where the strings are being stored, especially with the code below.
Code:
for (int i=0;i<number;i++){
printf("enter %d th string::",i+1);
scanf("%s",str[i]);
}
I know that it's asking the user to enter strings, which will be stored into the 2d array. I just don't understand how it's being stored. Will it be placed in the 1st column or 2nd row or something?
C++ :: Implement Flocking Algorithm
Mar 25, 2013I'm trying to implement the flocking algorithm in C++. I've tried to implement it myself by making all the particles 'home-in' on the player. When 2 particles then collide within their larger bounding boxes they home-in to each other. And when the 2 particles are actually touching they repel each other until they are outside of their bounding boxes and find another particle to home-into.when I run my application the particles all home into the player and come to a stand still along the Y-axis above the player.
All the particles in question are stored in a Vector, with a pos and velocity.
for(int i = 0; i < swarm.size(); i++) {
for (int j = 0; j < swarm.size(); j++) {
if (swarm.at(i)->getParticleModel()->getPosition().x < gameObjects.front()->getParticleModel()->getPosition().x) {
if (swarm.at(i)->getParticleModel()->getTouching() == false)
