C# :: Field Initializer Cannot Reference The Non-static Field / Public Var
Apr 12, 2015So I have this class
class DataBase
{
// Change the connection path here to your own version of the database
public SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)v11.0;AttachDbFilename=|DataDirectory|UberDatabase.mdf;Integrated Security=True;");
public DataBase()
{
}
}
And in the same namespace as this class I have a form that calls it like so:
DataBase dBase = new DataBase();
SqlCommand trythis = new SqlCommand("Register", dBase.con);
However, I'm getting the field initializer error on dBase.con. I'm not sure why, but when I call the database from another file (program.cs) it works fine this way.
C :: Produce Image Using GD Graphics Library?
Mar 20, 2013I am trying to produce a image using GD graphics library. I can succesfully display my image, however I cant display this image along with a printf function too?
Code:
#include <stdio.h>
#include <gd.h>
int display_picture()
{
gdImagePtr gdImage = gdImageCreate( 50, 50 );
FILE *jpgFile = NULL;
[Code] ....
The picture displays but not hello.
C :: Produce A Rectangle Out Of Asterisks Using While Loops
Jan 30, 2015 I am new to C and am unfortunately racking my brain against this simple assignment. I believe the task is to produce a rectangle out of asterisks using while loops, yet I can only produce an "L" shape. We were given a code, with syntax errors included.We are to correct the errors and test.
Code:
#include <stdio.h>
/*Houghton, Micah*/
/*ET2560 - Cordova*/
/*Unit 5 Lab - Programming Loops*/
int main(void) {
int length, width;
int lcount, wcount;

C# :: How To Add A Timer Or Loop To Produce RSSI Value
Oct 24, 2014I have a code which basically produces the RSSI value in a command prompt window once i run it but i want to add a function to it which would let the RSSI reproduce itself (once every 5 seconds or something) once its run without having to physically compile it every time.

C :: What Is Left Most Asterisk Doing
Apr 1, 2014I encounter this from a library:
( *(reg8 *)(pinPC) |= CY_PINS_PC_DATAOUT)
From my understand the cast (reg8 *) applies to the result of the bitwise OR. But what is the left most asterisk doing?Is it just dereferencing the casted pointer?
C++ :: Asterisk Bar Graph
Feb 12, 2014 i have to make a programs that prompts the user to enter quiz grades and add them up. For examples the user enters 6 test grades they are out of 5 so he enters 0-5 and i store them in the array. This part works great but now i have to print out a bar of vertical asterisks for every part too. So if at the end we have one test grades that are 2 grades of 1 points, 1 grade of two point, 2 grades of three point and 1 grade of 5 point it will have to display them as this
There are 2 grades of 1
There are 1 grades of 2
There are 2 grades of 3
There are 1 grades of 5
i need to do for loops but i am stuck on what to count too and what to print i know i will need cout << "*" and a couple of spaces.
#include <iostream>
using namespace std;
int main (){
int size;
int tests;
int a[6]={0};
cout << "How many quiz scores will you enter: ";
cin >> size;

C :: How To Change The Numbers Into Asterisk
Oct 10, 2014i have my basic C program here (i'm new to C language):
Code:
#include <stdio.h>
int main()
{
int grade;
int A=0;
int B=0;
int C=0;
int D=0;
int E=0;
[Code]....
As you can see, it's only for counting how many students got the grades from A to E, but the problem is that i need to change it from numbers into asterisk
for example: 4 students got the grade A, and 3 students got the grade B
instead of displaying
A=4
B=3
i want it to display
A=****
B=***
C++ :: Produce Normal Distribution Random Number Several Times
Aug 22, 2014I wrote the following program shown below that produces a normally distributed random number several times, and then takes the average of them. The problem that I have been having though is that the output it has been producing is 0.0288385 despite the fact that I set the mean of the normal distribution to be 0.1. Why this output value would be so far off from 0.1 despite having averaged over such a large number of random numbers namely 10,000 of them? Also, how to randomly seed this random number generator such that it gives a different value each time its run perhaps by seeding it with the windows timer? Below is the program.
#include <iostream>
#include <random>
using namespace std;
int main() {
default_random_engine generator;
normal_distribution<double> distribution1(0.1,3.0);
double number1,sum,n;

C :: Nested Loops - Asterisk Diamond
Jul 11, 2013Getting close but I think I am stuck on the second loop. The input you put in will be doubled (and it's not supposed to).

C++ :: Place Two Asterisk Triangles On Top Of Each Other But Only Using 3 For Statements
Oct 19, 2014I have to place two asterisk triangles on top of each other BUT only using 3 for statements. I have gotten the first one:
for(int a=1;a<=10;a++) {
for(int b=1;b<=a;b++)
cout << "*";
cout << endl;
}
I need the output to look like this:
*
**
***
****
*****
******
*******
********
*********
**********
*
**
***
****
*****
******
*******
********
*********
**********
The only kicker is I can have a total of 3 nested for loop statements.
C++ :: Asterisk Diamond Is Printing Out Wrong
Sep 6, 2014I feel as if I'm so close and I'm just messing up a value somewhere, but I am at a loss as to what I should change. Here is my code:

C/C++ :: Printing Asterisk Along A Function Of Y Columns
Jun 18, 2014The assignment is to plot the functions, by implementing a function having the following prototype:
void plotPoint(double y);
This function should print a single "*" symbol, in a position determined by the value of y, and then a newline. The position of the * symbol can span over 80 columns: each column should represent a delta of length 0.1 in the value of y, and the zero should be placed on the 40-th column.
For example:
• placePoint(0) should print the * symbol on the 40th column
• placePoint(0.1) should print the * symbol on the 41st column
• placePoint(1) should print the * symbol on the 50th column
• placePoint(-1) should print the * symbol on the 30th column
Here is what I have so far:
#include <iostream>
#include <cmath>
int a;
int b;
int x;
int y;
int Func1(double a, double b )/>
[Code] ....
I'm lost now as to where to go to plot. I know that depending on the option chosen I call the corresponding function to return a value for y which is just then plugged into a function to plot it on columns of y.
C/C++ :: Stopping Case For Asterisk Pattern?
Dec 1, 2014So, I'm going to write a recursive function for a asterisk pattern but I'm stuck figuring out how to create a stopping case for it, better yet, I'm unable to describe the pattern completely.
*
**
-*
****
--*
--**
---*
********
-----*
-----**
------*
-----****
-------*
-------**
--------*
( - represent white spaces )
What I've been thinking:
* Every odd row has 1 * with 1 incremented white space
* Every "pair" of asterisks equals 8 total (EX. 8 one pair *'s, 4 two pair *'s, 2 four pair *'s)
Unfortunately, that's all I got. how I can represent this as I function. Once I figure out what my stopping case should be, I think I can do the coding on my own.

C/C++ :: Read From Dat File And Produce Output On Screen - Error C2664
Feb 5, 2014My professor wants me to write a program that will read from a dat file, and produce an output on the screen based on the file. I don't understand why I am getting this error. I suspect it has something to do with the number of characters I've told it to read.
#include<iostream>
#include<iomanip>
#include<fstream>
#include<assert.h>
#include<string>

C++ :: Why Asterisk Required On Smart Pointers For Assigning Value
May 19, 2013When i try to compile this code it gives me a error during run-time saying "*program name* has stopped working"
Code:
#include <iostream>
#include <memory>
using std::cout;
using std::endl;
using std::unique_ptr;
[Code] .....
Why is this happening? Also why do you need the asterisk on smart pointers to assign them a value? Is it just because, or is there a reason.

Feb 25, 2013What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?

C :: Sorting Has To Be Based On Int Field
Feb 16, 2013I have a file which has records with 2 fields--one int and one float..what is the best way to sort it?
The sorting has to be based on the int field(the first field) (each time the program runs the file might end up with some hundreds of records).
