i have code for write on console and change the text color and backcolor and clear screen(and much more) inside of a nice class console.
these function change the text color and back color:
void SetColorAndBackground(int ForgC, int BackC=0)
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), ForgC|(BackC<<4) );
}
but is there any way for blink the text?
Use a loop to constantly change the backcolor to the forecolor and back again. You might need an extra delay loop in there as well.
i'm trying do that and i must put that loop on a thread..
#include <iostream>
#include <windows.h>
using namespace std;
void gotoxy (int x, int y);
int main()
{
while (true)
{
gotoxy(0,0); // move to where we want to output
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), 7);
string Text="hello world";
char *EmptyText;
EmptyText=new char[ Text.length() ] ;
int i;
for( i=0;i<=Text.length();i++)
{
EmptyText[i] = ' ';
}
EmptyText[i] ='\0';
cout << Text; // overwrite the current output
Sleep(1000);
gotoxy(0,0); // move back to the start of output
cout << EmptyText; // this will reset the output to blank
Sleep(500);
}
cin.get();
return EXIT_SUCCESS;
}
void gotoxy (int x, int y)
{
COORD coord; // coordinates
coord.X = x; coord.Y = y; // X and Y coordinates
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord); // moves to the coordinates
}
Here's some examples of how others have done that, perhapse they can be of help:
by some reasons i prefere my own code:
- for change the textcolor and backcolor;
- the loop will be like a thread;
- and i can change the caret position ;)
but i get some errors with my multithread class :(
do me a favor see my last thread: http://www.daniweb.com/software-development/cpp/threads/466459/multithread
after resolve that i will came back here

b->BackColor=BackColor;
b->TextColor=TextColor;
b->x=x;
b->y =y;
_beginthreadex(NULL, 0, BlinkLoop ,&b, 0, NULL);
}
finally i have the code, but i belive the error is from pointers... because the windows tell me that the program stops to working and then close it.
can anyone advice me?
line 23: failed to allocate memory for the null string terminator.
Lines 37 and 39: remove +1 from Text.Length().
finally i have the blink working:

why (int)p->Text.length()+2)??
because some issue..i don't know, if i don't use it the text isn't showed... sorry, but test it and see yourself...
the colors aren't programmed, but works fine

sorry about that. or it's compiler mingw bbug, i don't know...

(readers don't forget add the gdi32 library to the linker options)
i left a comment for the readers for avoid problems in other compilers.
like you see now we can use colors ;)
isn't perfect because of 1 thing:
TextOut(hDC, rt.left, rt.top, " ", strlen(" ")+1);
why don't print all space characters?
(i realy mean spaces, because the others characters works fine)
now i have a new version of the blink text:

it's more cool, but less colors.. here we just use the console colors(they are 16).
thanks for all
Cool :)
thanks for the comment..thank you.
sometimes my brain come with something ;)
i accept sugestions for timer loop and feedbacks;)
how can i make a specific text in console blink?
