Project description: Delivery: Visual component for VS 2008 (C#) The required component is an extended TextBox (System.Windows.Forms.TextBox) with the additional requirement, that each text line will have its own font and color (bg and fg). The reason why I can not use RichTextBox, is that it is too slow. I will accept performance which is equal or better than plain TextBox. Summary of requirements: 1. Look and feel of a TextBox. 2. Comparable performance. I will test it. 2. Support TextBox API, plus: 3. Add a simple, clear API properties to set the font & color of each line. For example: myTextBos.LineFont[1000] = mtFont; myTextBox.LineForeColor[1000] = Color.Yellow; myTextBox.LineBackColor[1000] = Color.Blue; You are free to come up with something else, as long as it is easy to use and clear. 4. If no color/font is set for a line, the parent's TextBox.Font and TextBox.ForeColor are used. 5. Support large files (>10M characters.) 6. Integrated into the toolbox of VS 2008. 7. I don't care if you extend TextBox, RichTextBox, or whichever control you choose. 8. Provide the documented source code and anything required to integrate into the VS toolbox. 9. In C#. You may use native Win32 with DllImport or else. Thanks. Keywords: Application Development, sharp, c
