C++ :: Can't Refresh Checkers Board On Application
Dec 6, 2013
I Cant get my checkers game board to refresh every time i make a move. i have system("cls") But it does nothing of the sort.. To move a pice ive created an illusion which swaps one pieces appearance with another :
I am doing a checkers program in C and were not allowed to use standard C99. Things are going relatively well so far. I have 2d array that acts as a matrix for my board and have ways to check if a space is empty and if it is occupied by a specific players chip.
Right now I have a giant messy method that I will split up sooner or later but Im just trying to understand and build the logic. It looks like this:
Code: void isValidMove(int origin, int dest, int player) { int rowDiff = abs(origin%8 - dest%8); int possibleMoveLeftUp = origin - 9; int possibleMoveLeftDown = origin + 9; int possibleMoveRightUp = origin - 7;
[Code] ....
So although its not pretty i think the logic is sound. I can tell whether or not a player is attempting to make a move or a jump. I haven't implemented make_move() yet but thats no problems. My biggest deal is that I need to find a way to tell the user he has to jump if its available. I feel like this is a very difficult task for me to grasp and is more about algorithm logic and math then the C language which is what the course is for.
So, how I could loop through all of a specific players chips and see if that player has an available jump. Also if he does then the jump has to be taken and then checked again as if there is another legal jump then it needs to be taken as well until their are no jumps left. Of course there could be 2 routes available, but I think I could deal with that if I just could come up with a reasonable way of checking....
I am trying to draw a grid for checkers. I could draw a square at the starting point from origin with the code below(attached the pic below how it looks) however I am not being able to draw a grid when the program runs.
#include "ccc_win.h" // GameDemo.cpp // Shows how to place a piece accurately on a grid after a mouse click. #include "ccc_win.h" // for graphics classes and functions using namespace std; int ccc_win_main(void) // main function for graphics program
I have a datagrid, which has a column called Status. In the database, the field is a text field that can have the values up, down, or danger.
I needed to display the status as a "light" as per client request, so I have a StatusToImageConverter class that receives the status, and returns the proper image to display in the datagrid column. Works fine.
Now the issue I am having... I have a combo box above the datagrid for the user to filter the results if desired. The filtering works fine, but the newly displayed devices do not have their status light. In the Status column, nothing appears after the user filters. I think it may have to do with the fact that I am not re-initializing the datagrid, but just refreshing it? That's just my educated guess.
XAML: In the UserControl Resources:
<local:StatusToImageConverter x:Key="ImageConverter" /> In the DataGrid Control: <DataGridTemplateColumn Header="Status" IsReadOnly="True"> <DataGridTemplateColumn.CellTemplate>
I would like to know how to make Lynx follow meta refresh links automatically, At the moment it just provides a "clickable" link you can accept the refresh. I would like this to be automatic.
--- Initial problem ---
We have a DB Backup script written in PHP/HTML and uses the page refresh to loop the backup (every 2 minutes). Using a full fledged browser is not really an option on our machine as the resources are very tight. So we tried Lynx and it has the perfect footprint but the only problem is it doesn't refresh the page.
I'm thinking I just need some way to force Lynx to reload the page after the time has elapsed. Maybe create a new function that starts a timer and hold the url until the timer ends then force Lynx to visit that url. Im a PHP Procedural kinda guy and I cant think how to set this timer event safely without corrupting or crashing the program or creating memory leaks.
(source code im using: [URL])
This is the function that handles meta refresh.
Code: /* * Given a refresh-URL content string, parses the delay time and the URL * string. Ignore the remainder of the content. */ void LYParseRefreshURL(char *content, char **p_seconds, char **p_address)
I've been using a timer to refresh the listview on my application, but after half a second, I get the error message at first try/catch method in RefreshPlot() in PlotComponent.cs:
Quote An exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in Marketplace.exe but was not handled in user code
Additional information: There is already an open DataReader associated with this Connection which must be closed first.
I have a Windows service that may change the timeout of the logon screensaver in Windows (as described here.) To do that I change the following registry key to the timeout in seconds:
//user list view da = new SqlDataAdapter("SELECT * FROM [user]", con); DataTable t = new DataTable(); ds = new DataSet(); da.Fill(ds); t = ds.Tables[0]; listView1.View = View.Details;
[Code] ....
I tried with datagridview.refresh, update but its not working can any body sugesst me what to do for refresing the data ....do timer we have to use..? if yes then how ...?
I'm writing a version of the classic Snake game. However, my board is not printing correctly. The right hand border is in the incorrect location. Also, when I randomly generate where the food ('X') is located, it only generates on the edges of the boundaries.
#include <iostream> #include <cstdlib> using namespace std; const int ROWS = 21; constint COLS = 61;
I'm programming tic tac toe but the board is not showing numbers, and it is simply stating the winner without any input: (the win conditions are not complete, but it shouldn't matter).
#include <iostream> #include<string> using namespace std; //Write a two-player tic-tac-toe game; use enums when possible to represent the values of the board
Im trying to make a Tic Tac Toe board for an assignment. Right now it compiles fine but when I enter an x or o it does not update the board it just prints out the '.'s that the board is initialized to. Also, when I get to player 2 the board will printout twice so its 6 rows or 3 columns. The project uses a main to ask who starts then goes to a play function that asks for inputs and calls the makeMove function to place the x's and o's and the print function to display the updated board.
bool Board::makeMove(int rowIn, int columnIn, char currentPlayer) { if (playBoard[rowIn][columnIn] == '.') { playBoard[rowIn][columnIn] = currentPlayer; return true;
What happens if I make a server application using tcp protocol and then establish connection with a client application but the server crash and then the client send data. Will the data be lost or the system will continue trying to send it?
Okay so this is part of a small uni module around the arduino board. The task is to simulate traffic lights at a junction. At the moment my code below runs through the sequence with 2 seperate lights. When one set of lights turns RED , the other turns GREEN.In my main loop method I need to add a button for a crossing. I want to be able to check if the button is pressed at each of the delays but do not want to have to hold it down.I have thought about putting it at the top of the loop but then the program will only check if button is pressed in that point therefore the user will have to hold it down?
Code:
int green1 = 13 ; int amber1 = 12 ; int red1 = 11 ;
int green2 = 6 ; int amber2 = 7 ; int red2 = 8 ; }
/* This is what I have so far what i am trying to do is to initialize the arrays at zero and output the board to the screen. Part of the problem is the user has the option of the board size. All this is suppose to do is to output the board to the screen. I am having problems understanding 2D Arrays. */
using namespace std; int main() { const int BOARD_MAX = 10; // Maxinum Board size. const int BOARD_MIN = 3; // Minimum Board size. array = [COL]; array [ROW];
I 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?
I am working on my senior project and my currect task is to make a menu. I dont know what the best way to do it. my code is not complete and i am completely lost. code found below:
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.
Is there any standard USB protocol which i can follow to send data to my embedded board(and vice versa). I have no clue on USB programming using c,is there any example code i could follow,
