VB_Name = "Form1" Attribute VB_Creatable = False Attribute VB_Exposed = False '' Format2 - a portable palette generator for Formula One 3.0 OCX '' Description: '' Allows you to view and alter a palette and then save the entries '' as VB code that you can later load into a project as a module to '' setup a custom palette. The palette is layed out as it appears in '' the custom color combo boxes (as on the FormatPatternDlg). '' The Formula One palette was designed with Excel compatibility in '' mind. The Excel palette has several (8) entries that are duplicates '' and can be improved upon for several situations. One is color '' coordinating a First Impression Chart with Formula One patterns. '' The Palette1 module was extracted from First Impression. Now that '' live charts can easily be placed on a Workbook, you can format your '' data to match chart series colors or even data point colors. '' This project also illustrates how handy Formula One can be as a programming '' aid. For instance, I constructed the code in the Palette1 module by '' copying the RGB values from First Impression into columns A, B, and C '' of a Formula One Workbook. In cell D1 I placed the formula '' =".PaletteEntry(" & ROW() & ") = RGB(" & A1 & "," & B1 & "," C1 & ")" '' and then copied that formula down to row 63. I then removed a couple '' of colors since the First Impression palette has more entries than '' the Formula One palette. This was simple since the palette entries '' were automatically fixed up when the row was deleted. Next, cut and paste '' into the VB code window which again saved much typing. Another way Formula '' One is used is as a text formatter. When you save a file in this '' project, the code is placed in Formula One and saved as a text file. '' Why use this? Often it is hard to get just the right look for the finished '' project. You want just the right colors and patterns for your formatting '' and spend a lot of time getting that look. This doesn't have much to do '' with the problem solving you are doing but in many cases is as important. '' Often you will find colors that suit you and want to use them over. '' This project provides a little different way of creating a palette but '' more importantly, allows you to save your work and easily reuse it. This '' allows you to spend more time on the important code - the code that solves '' the problem. If you build a collection of these reusable modules, you can '' leave a lot of the UI till the end and then easliy and quickly change it '' to suit customer desires.
