C# :: Accessing Data From 3rd Tier Of Hierarchical Grid?
Jan 24, 2014
I've got a Dev Express hierarchical grid and I need to which row is in focus in the level that's in focus. In the code below I need to replace "gridControl1.FocusedView.GetRow(0)" with "gridControl1.FocusedView.GetRow(x)" where x is the row number in the focused row but I can't find a property for it.
private void gridControl1_Click_1(object sender, EventArgs e)
{
//int i = gridView1.GetFocusedDataSourceRowIndex();
[Code]....

I'm trying to extract data from a grid, it's a Dev Express grid. I have got an object which if I hover over it in debug mode shows me the data I'm after. In the code below if I hover over "row" I can drill down through "Row" and then "ItemArray" and I can see the data I want in an array but I can't find how to get at it.
private void gridShowUsers_Click(object sender, EventArgs e)
{
Object row = gridView1.GetFocusedRow();
string [] rowarray = new string [50];

why filtering don't work??
This is code for load data into dataGridView
private void Izvestaj_Load(object sender, EventArgs e) {
connection.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:UsersTomyDesktopzadatak2zadatak2fedek_OldVersion(2002-2003).mdb;User Id=admin;Password=;";
dt = new DataTable();
OleDbDataAdapter sda = new OleDbDataAdapter("SELECT korisnici.korisnik,dogadjaji.dogadjaj,Tomislav.Datum
[Code] .....
And this is code for filtering by typing into textbox, when type nothing happening
private void textBox3_TextChanged(object sender, EventArgs e) {
DataView DW2 = new DataView(dt);
DW2.RowFilter = string.Format("dogadjaji.dogadjaj LIKE '%{0}%'", textBox3.Text);
dataGridView1.DataSource = DW2;
[Code] .....
And this is by filtering on dataPickers, range of date, and show me what happens on that dates, but show me exception when click button
private void button1_Click(object sender, EventArgs e) {
if(dateTimePicker1.Value>dateTimePicker2.Value) {
MessageBox.Show("Takav opseg nije moguc. Datum Od mora biti veci od datuma Do.", "Opseg datuma", MessageBoxButtons.OK, MessageBoxIcon.Error);
[code].....

I have a program which generates lots of data points in 2D (x and y co-ordinates). Perhaps 1,000,000+ of these points. These are floating point numbers. The values all fall within a specific range -R/2 and +R/2.
I want to impose an 'imaginary' grid. Such that I can collect the number of each of these points falling within a specific grid location. The actual 'grid' size is variable.
Should I try and collate this data from my C++ program and then post-process it in some other s/w like matlab?

i m working on a simple project, i want to populate my text boxes and comboBoxes through DataGridView, means when i double click on cell content then the text boxes are populated.my question is that if i have to populate comboBox with the specific value then what i have to do then because comboBox.selectedItem is an object but my class property is a string..
e.g
combobox shows 30 days in it and my class is Code: class account
{
public string day{set;get}
[Code]....
but that does not happen because "comboBox.selectedItem" is an object so if i have to do that what i have to do then?

I need to take a single column and all the rows in the column from a datagridview to a listbox using a for loop. My code is giving me no errors just not showing any data in the listbox.
private void frmProject6_Load(object sender, EventArgs e) {
// TODO: This line of code loads data into the 'enrollmentsDataSet.Enrollments' table. You can move, or remove it, as needed.
this.enrollmentsTableAdapter.Fill(this.enrollmentsDataSet.Enrollments);

I was wondering what the best way was to access data outside the function it was created in. I have the user input a data in a custom namespace function, and now im trying to access all those data points in a different function.

I have a queue of structs. I would like to access one of the two pieces of data at the front of the queue that each struct maintains.
Here is some of my code:
#include <iostream>
#include <cmath>
#include <cstdlib>
#include <iomanip>
#include <queue>
using namespace std;
[Code] ....
What I am asking is how do I get the priority of the struct item at the front (lane1.front()), in this case?

Basically, I've got one object which has to access private data in another object... and can't.
Here's the specifics: I'm writing a little war game program where players deploy units (soldiers, tanks, planes, etc.) onto a gameboard. Players and Units are modeled as objects:
Code:
class GameUnit {
public:
string GetName() {return Name;}
protected:
string Name;
};
class Player {
[Code] ....
Here's the problem: In the above code, Player's ListUnits() function doesn't work because Player can't access GameUnit's GetName() function.
Specifically, here's the compiler's error message:
Code:
In file included from Main.cpp:18:
Player.h: In member function 'void Player::ListUnits()':
Player.h:47: error: 'GetName' undeclared (first use this function)
Player.h:47: error: (Each undeclared identifier is reported only once for each function it appears in.)
I've tested enough to realize that the problem is the GameUnit::GetName() function is a public function within the GameUnit object. Why can't a Player call this function? Making both friend classes of each other doesn't work.

I have a header file that declares some fields as private, I then have a class that I need to compare two of the objects' information for equality but neither of them are the calling objects. I cannot alter the header file. How would I go about comparing private data fields? I will enter a brief bit of code for clarity.
Code: // Header File
// stuff.h
class stuff
{
private:
int* arr[20];
int size;
};
bool equal (const stuff& a, const stuff& b);

I am parsing a binary data file by casting a buffer to a struct. It seems to work really well apart from this one double which is always being accessed two bytes off, despite being in the correct place.
Code:
typedef struct InvoiceRow {
uint INVOICE_NUMBER;
...
double GROSS;
...
char VAT_NUMBER[31];
} InvoiceRow;
If I attempt to print GROSS using printf("%f", row->GROSS) I get 0.0000. However, if I change the type of GROSS to char[8] and then use the following code, I am presented with the correct number...
Code:
typedef struct example {
double d;
}
example;
example *blah = (example*)row->GROSS;
printf("%f", blah->d);

My code is here [URL]
void Player::Display() const
{
cout << "
Player Name: " << GetName() <<
"
Grade: " << GetGrade() << "
G.P.A. " << GetGPA() << endl;
}
The problem occurs in here, I get access violations, is there a way to this while keeping Display const or is this code valid and my problem is somewhere else and not being caught in the debugger? I tried to make the return types const - but that didn't work .....
//Getters need const twice for this to work?
const char* Player::GetName() const {return m_name;}
const int Player::GetGrade() const {return m_grade;}
const double Player::GetGPA() const {return m_gpa;}
[Code].....

Code: There is a rectangular grid of numbers. The grid has m rows and n columns. So it has m*n cells in total.The rows are numbered from 1 to m and the columns are numbered from 1 to n. The top most row has number 1, the row next to it has number 2 and so on. Similarly, the left most column has number 1, the column next to it has number 2 and so on. Each cell in the grid has a unique coordinate which is (x, y) where x is the row number and y is the column number of that particular cell.
Each cell in the grid has an integer in {0, 1, 2, 3, 4, 5, 6 ,7 ,8}. Number in cell (x,y) is number of mines in neighboring cells (cells have at least 1 common vertex with cell (x,y))
Your task is to find grid of mines, i.e display an m*n grid of numbers {0, 1} (cell (x, y) is 1 if there is a mine in cell (x, y)).
Input
First line of the input contains two space separated integers, m and n. Next m lines, each line has n numbers in {0, 1, 2, 3, 4, 5, 6 ,7 ,8}.
Output
A grid of numbers {0, 1}

I'm trying to create a grid using the following characters: !, @, #, $, &.
It's an 8 x 8 grid, and should contain the characters in no particular order (trying to create a Bejeweled-like game).
I already defined the width and length to be 8, so:
#define WIDTH 8
#define LENGTH 8
Code:
void makegrid(char grid[])
{
int j;
int k;
for ( j = -1; j < LENGTH; j++ )
{
for ( k = -1; k < WIDTH; k++ )
{
/* I don't know what to type here anymore :( */
}
} }

I have a map that is full of 4+ rooms each with one randomly selected door on one of its sides. I need to create a tunnel connecting all of the doors together. I'm not sure the best way to do this A* seems to complicated for me to do at the moment and I cannot think of a way to connect these rooms.
My world is currently a vector<vector<Tiles>> and the tiles contain entities like tunnel, wall, stair, floor, etc.

How do you use a stored procedure with a WebGrid? Our coding standard say we cannot write sql statement directly in the code to include HTML.
[var Grid = new WebGrid(DB.Query("Select * from Menu")]
The above call must be a call to a stored procedure.

So my program is to check if a certain 9x9 sudoku grid is valid. i have to get the input through command argument. so for example.
./a.out sudoku.txt
So we have make my c program to use FILE I/O open and what not
program behavior must be as follow File does not exist.File contains something other than a sequence of 81 integers (too many, too few, non-int).
One or more of the values is not in the range 1..9 Violation of Sudoku rules (this is the big one!) In case 4, you should report the violation (or any one of the violations if there are multiple -- you do not need to exhaustively enumerate all violations).
For example: Row Violation: entries (2,2) and (2,6) are both equal to 7. (Similarly for column and box violations). All i know is that i need to make a 2d 9 by 9 array

Write a menu driven program that will fill grid with values between 1 and 100. Begin the program by declaring a array of type int. Then present the user with the following menu
Enter 1 to add
Enter 2 to edit
Enter 3 to delete
Enter 4 to search
Enter 5 to display
Enter 0 to Quit
Each item of the menu must be implemented as a function. The program should Only allow values between 1 and 100
Always ask the user to apply coordinates for the cell to be changed
Flag an error when try to delete or edit a cell with a zero (0)
Flag an error when try to add to a cell that is not blank
Display the complete and nicely formatted grid when option 5 is selected

I have to make a grid 40 X 40 with random numbers 0-9. I have already done this and it prints out great. My problem is I need to be able to choose a row number and output the sum of the number in that row. Here is what I have so far.
#include <iostream>
using namespace std;
int main(){
int Values[40][40];
int rows, cols;

implementing a game of chess, i was able to easily implement the grid with an 8x8 multidimensional array.but here is the case I need to implement a grid made of hexagons(six sided but in future may be seven sideded or eight may be needed): like a beehive something.
How can such a grid be implemented in c++ taking notes of coordinates and borders and stuff? From where i can start working from? this grid has to be just like the chess grid only we got six sided boxexs instead of four,

I don't really have an issue with the math behind this, rather it's more with the code structure itself. Basically, every row is right, except for the last row. The last row (year) needs to be depreciated by the value at the beginning of the last row (year).

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
