using string in SetCons...

[Hex213]

I have this code:

void text_color(string color1, string color2, string color3)
{
string colortmp, colortmp1;
if((color2 == "NULL") && (color3 == "NULL"))
{
colortmp = "FOREGROUND_" + color1;
SetConsoleTextAttribute(h, colortmp.c_str() | FOREGROUND_INTENSITY); // Error line
}
else if(color3 == "NULL")
{
colortmp = "FOREGROUND_" + color1;
colortmp1 = "FOREGROUND_" + color2;
SetConsoleTextAttribute(h, colortmp.c_str() | colortmp1.c_str() | FOREGROUND_INTENSITY); // Error line
}
else if(color2 == "NULL")
{
Sleep(1);
}
else if(color1 == "NULL")
{
SetConsoleTextAttribute ( h, wOldColorAttrs);
}
else
{
cout << endl << "error to load paint" << endl;
}
}

And error is:
invalid operands of types `const char*' and `int' to binary `operator|'
invalid operands of types `const char*' and `const char*' to binary `operator|'

please help

You don't need to include the text that you are trying to modify(what gave you the idea to OR it?). Here is the manual page describing the "SetConsoleTextAttribute()": https://msdn.microsoft.com/en-us/library/windows/desktop/ms686047(v=vs.85).aspx

You'll notice that it is a global setting for the console, not a setting per line of text.

I tryed set color of one for line text. But I could not run program. I don't know how I will continue. Can you help me to do differently?

[Thomas1965]

#include <iostream>
#include <windows.h>

using namespace std;

int main() 
{
  HANDLE hConsoleOut = GetStdHandle(STD_OUTPUT_HANDLE);
  SetConsoleTextAttribute(hConsoleOut, FOREGROUND_RED);
  cout << "Hello World!\n\n";
  SetConsoleTextAttribute(hConsoleOut, FOREGROUND_GREEN);
  cout << "Hello World!\n\n";
  system("pause");
  return 0;
}

Here is a list of color codes:

I know this method but whether it can be done even with variables of type String

[Thomas1965]

Windows accepts only a WORD as color. Of course you can write your own code to convert a string to a WORD like:

WORD GetColor(string colorName)
{ 
   // Your code here
}

Please. Can you show me extended code or show us an example? Because I don't know quite how to use it.

[Thomas1965]

#include <iostream>
#include <string>
#include <windows.h>
#include <ctype.h>

using namespace std;

WORD StringToColor(string colorName)
{ 
  const int FOREGROUND_WHITE = 7;

  for (size_t i = 0; i < colorName.size(); i++)
  {
    colorName[i] = toupper(colorName[i]);
  }

  if (colorName == "RED")
    return FOREGROUND_RED;
  else if (colorName == "BLUE")
    return FOREGROUND_RED;
  else if (colorName == "GREEN")
    return FOREGROUND_GREEN;
  else 
    return FOREGROUND_WHITE;
}

int main() 
{
 
  HANDLE hConsoleOut = GetStdHandle(STD_OUTPUT_HANDLE);
  SetConsoleTextAttribute(hConsoleOut, StringToColor("RED"));
  cout << "Hello World!\n\n";
  SetConsoleTextAttribute(hConsoleOut, StringToColor("GREEN"));
  cout << "Hello World!\n\n";
  system("pause");
  return 0;
}

Thank you very very very much. :)
