Have you looked in the Web: http://www.functionx.com/bcb/applica...orselector.htm

About splitting string in the tokens - you can use stringstream for example

Sorry for the imagine not being visible, the page died on me, anyway i managed to fix the problem myself into obtaining the RGB values from a random given color.

Code:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
ColorDialog1->Execute();
CSpinEdit1->Value = ColorDialog1->Color;
Memo1->Color = CSpinEdit1->Value;

CSpinEdit2->Value = CSpinEdit1->Value;
CSpinEdit3->Value = CSpinEdit1->Value/256;
CSpinEdit4->Value = CSpinEdit1->Value/256/256;

if(CSpinEdit2->Value > 255)
{
CSpinEdit6->Value = CSpinEdit3->Value * 256;
CSpinEdit2->Value = CSpinEdit1->Value - CSpinEdit6->Value;
}
if(CSpinEdit3->Value > 255 < 65280 )
{

CSpinEdit3->Value = CSpinEdit3->Value - CSpinEdit2->Value/256;
}
if(CSpinEdit1->Value >= 65280)
{
CSpinEdit5->Value = CSpinEdit4->Value * 256 * 256 + CSpinEdit2->Value;
CSpinEdit3->Value = CSpinEdit1->Value - CSpinEdit5->Value;
CSpinEdit3->Value = CSpinEdit3->Value/256;
}
}

Although simple it was a lot trickier then i expected to obtain the 3 values as i had to figure out how they designed the color scheme and appointed colours on the coordinates. I didn't want to create an entire new Colordialog from scratch,just get the rgb from the value given. It was tricky to see how much portion of every given primairy color was appointed to each color coordinate. Thanks so much for the time you've people decidate on helping people.

So basically you wanted something like
R = CSpinEdit1->Value & 0xFF;
G = ( CSpinEdit1->Value >> 8 ) & 0xFF;
B = ( CSpinEdit1->Value >> 16 ) & 0xFF;

Going the other way
CSpinEdit1->Value = ( B << 16 ) | ( G << 8 ) | R;
