This application is a HEX and HTML color clipboard


ColorCoder2 is the second version of my HEX & HTML Color wizard.
It is particularly useful in the Web and graphics design industry because it makes light work of RGB, HEX and HTML color codes. It also features an integrated clipboard manager that can store and monitor your clipboard entries as well as convert the color entry on-the-fly.

ColorCoder2 makes use of the Desktop Color Picker Application by Code Project User nd1279.

Using the Code

The code is formatted into different blocks of functions.

The following block converts the RGB colour values to hex and sets the control values:

/// <span class="code-SummaryComment"><summary></span>
/// Sets the color from hex
/// <span class="code-SummaryComment"></summary></span>
/// <span class="code-SummaryComment"><param name="hexValue">The Color value in Hex</param></span>
private void changeColor(string hexValue)
    colorLabel.Text = "";
        int tmpRed = 0;
        int tmpGreen = 0;
        int tmpBlue = 0;

        tmpRed = Convert.ToInt32(hexValue.Substring(0, 2), 16);
        if (hexValue.Length >= 4)
            tmpGreen = Convert.ToInt32(hexValue.Substring(2, 2), 16);
            if (hexValue.Length >= 6)
                tmpBlue = Convert.ToInt32(hexValue.Substring(4, 2), 16);
        //Set the Color Label
        colorLabel.BackColor = Color.FromArgb(255, tmpRed, tmpGreen, tmpBlue);
        //Set the Selectors
        redSelector.Value = tmpRed;
        redLbl.Text = tmpRed.ToString();
        redValue = tmpRed;
        greenSelector.Value = tmpGreen;
        greenLbl.Text = tmpGreen.ToString();
        greenValue = tmpGreen;
        blueSelector.Value = tmpBlue;
        blueLbl.Text = tmpBlue.ToString();
        blueValue = tmpBlue;
        //Set the HEX text box
        hexTxt.Text = hexValue;
        //Set the HTML text box
        htmlTxt.Text = "#" + hexValue;
        //Set the RGB text box
        rgbTxt.Text = "" + tmpRed + "," + tmpGreen + "," + tmpBlue;
        colorLabel.Text = hexTxt.Text;
    catch (Exception ex)
        colorLabel.BackColor = Color.White;
        colorLabel.Text = "Invalid Format";

Points of Interest

This application also makes use of the process class that monitors an external application and sets some values if the application is terminated.

    Since this is version 2 and I never posted version 1, it is as up-to-date as it can be.
    Any suggestions and addons are welcome.

The label on one of the text fields says "R, B, G", should be "R, G, B".
