This is a simple color converter, that converts RGB colour codes to HEX. It uses textbox control to display the color, three text boxes for Red, Green and Blue values, also 3 sliders if the exact rgb color is not known. To use the code, you need is the folowing: 4 Textboxes (don't rename them) 3 sliders (numbered 0 to 255) and label4 is the hex output
