C++ (Cpp) ExtractSubstring Examples

Example #1

File: Edittime_old.cpp Project: segafan/Construct-classic

void EditExt::OnPropertiesUpdate()
{
	// Parse string in r,g,b format and save in colorref
	CString r;
	CString g;
	CString b;

	ExtractSubstring(r, rgbStr, ',', 0);
	ExtractSubstring(g, rgbStr, ',', 1);
	ExtractSubstring(b, rgbStr, ',', 2);
	
	int red = atoi(r);
	int green = atoi(g);
	int blue = atoi(b);

	filter = D3D_ARGB(opacity, red, green, blue);
}
