C++ :: Clear Screen Without Blinking
Nov 4, 2013
I have a one simple question :D. I want to output to the console some symbols. Let's say that i have a loop.
for(int i = 0; i < 10; i++) cou << "* ";
Then I want to output other symbols but I want to overwrite the previous symbols. I know I can use system("cls"); but it blinks if I try to output the same characters. For example if I have:
for(int i = 0; i < 10; i++) cou << "* ";
system("cls");
for(int i = 0; i < 10; i++) cou << "* ";
After I run this code the first loop outputs ten "*". Then there is a blink and there are again ten "*" shown. How can I avoid this blink?

Is there any way I can clear only a selected part of the screen? (I'm aware of system("cls"))
For example, when you enter a date, and is wrong, could it just errase that input and only say "Wrong try again" without errasing everything else you where doing?
In this case, a function that only errases what is in the while
while(not wrong)
{
cout<<"DIA: ";
cin>>obj.dia;
cout<<"MES: ";
cin>>obj.mes;
cout<<"ANIO: ";
cin>>obj.anio;
}
PS: Also, is there any whay in which you can ask the user to enter the date DD/MM/YYY?

I am working on a simple calculator in C++ .... All works fine with the calculator up until the requirement for the user to input "do you want to go again y/n" .... What i want to happen is the screen to clear down and reloop to the enter name part....but i can't get it to do that
Program Description: To write and develop a programme where a user can input a cost or price of something before VAT our program must then process the input number and must output the price with the original value plus VAT
#include <iostream>// I must use this to start my programming
#include <string> // I have added this for the extension task so the user has to input their name
#include <iomanip> // this is to manipulate the text
#include <stdlib.h>
using namespace std; // using the "using namespace std" shows that i will be using standard text throughout this programme
[Code] .....

For my C programming module, I've been asked to create a program which is basically a ten question mathematics quiz or test if you like. Below is a copy and paste of my current, working program.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main () {
[Code]....
I am also trying to include into my program; If the user achieves 4 or less marks in the test, they are asked if they would like to repeat the test (have a second chance).
I have been asked by my Lecturer to ask the Question; "Would you like to try again" and the response is 'Y' for yes, 'N' for no. Would this be shown by:
char Y = Y;
char N = N;
printf("Would you like another go?");
scanf(%d%, &Y, &N);
And finally; If the user would like another go, then I am trying to include the code that clears the screen and then reloads the program?
What code is used to clear the screen and no clue what code is written to refresh or reload the program. I assume it's a loop statement or some sort.

I have created a simple WIN32 application. I inserted the function "IsDialogMessage" in the while-loop to make the tabstop key change the textfield. But when I insert the IsDialogMessage-function, the cursor won't blink anymore (it stays static). Is there a way to combine the two (tabstop key = change text field AND blinking cursor)?
Here's my while-loop:
MSG Msg;
while(GetMessage(&Msg, NULL, 0, 0) > 0) {
IsDialogMessage(window,&Msg);
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
And here I am creating the textfields:
hwnd = CreateWindowExA(NULL, "EDIT", NULL, //no title
WS_CHILD|WS_VISIBLE|WS_BORDER|ES_AUTOHSCROLL|WS_TABSTOP ,
xPos,yPos,width,height,
cWindow->window,(HMENU)502,
(HINSTANCE) GetWindowLong(cWindow->window, GWL_HINSTANCE),NULL);

so im trying to make a blinking cursor to give it a terminal feel, but it is speradic, since it is going at cycles instead of seconds. how can i fix this?
#include <SFML/Graphics.hpp>
int main() {
sf::RenderWindow App(sf::VideoMode(900, 750), "Fuck it. Uploads Happen.");
sf::Font
Font;

is there a way to stop the cursor from blinking in the output window(or showing up at all)?
Example:
cout<<"Hello world";
Output:
Hello world_
//where last character keeps blinking
I use DevC++ in Windows 7.

here is a nested stl map
typedef struct struct_RISCP {
float nSCPTotal;
int nSCPCount;
CString strIMEI;
std::map<UINT8, int> mapSection;
}RISCPSt;
map<stRncCellIdntyDmnType, RISCPSt>m_mapRISCP;
it occupied too much memory,i wanted to clear them(both outer map and inner map) ,some one told me you just need to call m_mapRISCP.clear(),then the mapSection (inner map) will be cleared automaticly,in other words, m_mapRISCP.clear() will clear both outer map and inner map.

I am trying to clear the first character of my array. The first two methods don't seem to work. The third method seems to but doesn't look like a good idea.
char operand[] = "abc";
//both methods seem to null it out
operand[0] = 0;
memset(operand, 0, 1);
printf("%s", operand);
//seems to work
memset(operand, 5, 1);

I need to clear a listbox from a class other than the form where it exists. Why this isn't working? I'm getting no error messages when I compile and I am seeing the Console.WriteLine text I also added in the same function. I can call this function from within my form and it behaves as expected. I tried setting the listbox to public despite the fact I wasn't getting protection level errors but that made no difference.
Just to clarify what I'm doing here... I have a form that includes a panel of user controls from another class. So there is a listbox on OtherClass and the listbox is in MyForm. Heres my code:
MyForm
public void ClearListBox() {
Console.WriteLine("echo");
listBox.Items.Clear();
} OtherClass
private void listBox_SelectedIndexChanged(object sender, EventArgs e) {
MyForm mf = new MyForm();
mf.ClearListBox();
}

I'm writing a program that converts hex to letters and writes the letters to a file.To write I'm currently using ofstream("output.txt" ios::app)But the issue with this is, is that everytime I run the program, it appends and doesn't write from the beginning of the text file.So what I want to know is, how do I clear the contents of a text file, before writing to it?

When creating an exception mask for a file, should an exception throw during a file operation, I can reset the state bits of the actual file using ios::clear().
Though after doing so, will the exception mask still throw an exception, thinking that the specified error state flags are still set to true? If so, how can I reset the exception mask so that it is ready to throw more exceptions should the appropriate situations arise in the future?

std::ostringstream ss;
ss.flush();

XMLString::transcode(buff.c_str(), tempStr, 99);

The buff at "Z" are stringed together with previous values. How do I resolve that?

I have a college project which is a car racing game using C++ and the old-school graphics library BGI. After I draw the map and placed the objects(Car,obstacles,road's borders etc..)I added Sleep(); function to the function named Obstacles(); but the problem is, I can't move the car with the right&left arrows.a
Another problem,If I added a cleardevice(); command all objects disappears only the obstacles function keeps working. the Code is here:
char c;
do{
c = (char)getch();
if (c == KEY_LEFT) {
x = x - 10, x1 = x1 - 10;
} if (c == KEY_RIGHT) {
x = x + 10, x1 = x1 + 10;
[code].....
note: this is not the whole code, it's only a small portion of it, not a debugging question only need a hint how to fix it.

I've got myself a 2d array
int[,] map = new int[100,100];
I've populate that will a bunch of 1's and 0's. The 1 represents a wall, and a 0 is dirt.
I'm looking for a way to clean up my blank spaces outside of my walls. Any algorithm I can use to identify these big areas and replace them with a '1'
for (int y = 1; y < map.GetLength(1) - 1; y++) {
for (int x = 1; x < map.GetLength(0) - 1; x++) {
// Inside here is where I was hoping to archive my work
bool draw = true;
foreach (Room room in rooms)
[Code] ....
Attached is an example of my output.As you will be able to see, there is a lot of brown. I want to fill the brown with walls, but leave space for a path between the rooms.The 'draw' bool is true when I'm outside of a room, just so I don't start throwing walls inside my room.
Example of what the array would look like (for those who don't know)
int[,] map = new int[100,100]
{
{0,1,1,1,1,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,1,1,1,1,0},
};
