EPOS 4 Excel (E4E) is a Microsoft Excel macro enabled workbook released as free opensource software under the GNU Lesser General Public License 3. E4E provides a basic electronic point of sale (EPOS) system. It is programmed in Excel VBA and uses Excel worksheets as the basis of its user interface. Excel, from Microsoft, is a powerful spreadsheet application for Mac, Windows, and OS/2. Excel was first released for the Mac. When it was ported to Windows 2.x, they started at version '2.0' to one up current Mac version. There was never a DOS version. Instead, DOS and 8-bit platforms used the older Microsoft Multiplan. Excel was later bundled as part of Microsoft Office.

Excel-DNA is an independent project to integrate .NET into Excel. With Excel-DNA you can make native (.xll) add-ins for Excel using C#, Visual Basic.NET or F#, providing high-performance user-defined functions (UDFs), custom ribbon interfaces and more. Your entire add-in can be packed into a single .xll file requiring no installation or registration.

Getting Started

If you are using a version of Visual Studio that supports the NuGet Package Manager (including Visual Studio 2019 Community Edition), the easiest way to make an Excel-DNA add-in is to:

1. Create a new Class Library (.NET Framework) project in Visual Basic, C# or F#.
2. Use the Manage NuGet Packages dialog or the Package Manager Console to install the Excel-DNA package:

3. Add your code (C#, Visual Basic.NET or F#):

4. Compile, load and use your function in Excel:

The Excel-DNA NuGet Package installs the required files and configures your project to build an Excel-DNA add-in.

Alternatively, get the full Excel-DNA download from GitHub, and work through the Getting Started page. The download includes a step-by-step guide to making your first C# add-in, and more information is available on the Documentation page.

More Details

Excel-DNA is developed using .NET, and users have to install the freely available .NET Framework runtime. The integration is by an Excel Add-In (.xll) that exposes .NET code to Excel. The user code can be in text-based (.dna) script files (C#, Visual Basic or F#), or compiled .NET libraries (.dll). Excel-DNA supports both the .NET runtime version 2.0 (which is used by .NET versions 2.0, 3.0 and 3.5) and version 4 (used by all newer versions). Add-ins can target either generation of the runtime, and concurrent loading of both runtime versions into an Excel instance is supported.

Excel versions ’97 through 2019 can be targeted with a single add-in. Advanced Excel features are supported, including multi-threaded recalculation (Excel 2007+), registration-free RTD servers (Excel 2002+) and customized Ribbon interfaces (Excel 2007+). There is support for integrated Custom Task Panes (Excel 2007+), offloading UDF computations to a Windows HPC cluster (Excel 2010+), and for the 64-bit versions of (Excel 2010+).

Most managed UDF assemblies developed for Excel Services can be exposed to the Excel client with no modification. (Please contact me if you are interested in this feature.)

Since Excel-DNA uses the Excel C API, porting C/C++ add-in code based on the Excel XLL SDK is very easy. (No more XLOPERs!)

The Excel-DNA Runtime is free for all use, and distributed under a permissive open-source license that also allows commercial use.

Latest Releases

The current version is Excel-DNA 1.1, released on 29 June 2020. This release included various bug-fixes and further improvements to the NuGet package build integration. Excel-DNA 1.1 is expected to be the final version with support for older .NET (< 4.5) and Excel (< 2007) releases.

Microsoft® Office contains a variety of tools that help people accomplish many personal and professional objectives. Microsoft Excel is perhaps the most versatile and widely used of all the Office applications. No matter which career path you choose, you will likely need to use Excel to accomplish your professional objectives, some of which may occur daily. This chapter provides an overview of the Excel application along with an orientation for accessing the commands and features of an Excel workbook.

Taking a very simple view, Excel is a tool that allows you to enter quantitative data into an electronic spreadsheet to apply one or many mathematical computations. These computations ultimately convert that quantitative data into information. The information produced in Excel can be used to make decisions in both professional and personal contexts. For example, employees can use Excel to determine how much inventory to buy for a clothing retailer, how much medication to administer to a patient, or how much money to spend to stay within a budget. With respect to personal decisions, you can use Excel to determine how much money you can spend on a house, how much you can spend on car lease payments, or how much you need to save to reach your retirement goals. We will demonstrate how you can use Excel to make these decisions and many more throughout this text.

Figure 1.1 shows a completed Excel worksheet that will be constructed in this chapter. The information shown in this worksheet is top-line sales data for a hypothetical merchandise retail company. The worksheet data can help this retailer determine the number of salespeople needed for each month, how much inventory is needed to satisfy sales, and what types of products should be purchased.

Work Started On Version 1.2epos 4 Excel Automatically

1. Locate Excel on your computer.
2. Click Microsoft Excel to launch the Excel application and present you with workbook options.
3. Click the first option; “Blank Workbook”.

Once Excel is started, a blank workbook will open on your screen. A workbook is an Excel file that contains one or more worksheets (sometimes referred to as spreadsheets). Excel will assign a file name to the workbook, such as Book1, Book2, Book3, and so on, depending on how many new workbooks are opened. Figure 1.2 shows a blank workbook after starting Excel. Take some time to familiarize yourself with this screen. Your screen may be slightly different based on the version you’re using.

Your workbook should already be maximized (or shown at full size) once Excel is started, as shown in Figure 1.2. If necessary locate the Maximize button as shown in Figure 1.3.

Data are entered and managed in an Excel worksheet. The worksheet contains several rectangles called cells for entering numeric and nonnumeric data. Each cell in an Excel worksheet contains an address, which is defined by a column letter followed by a row number. For example, the cell that is currently activated in Figure 1.3 is A1. This would be referred to as cell location A1 or cell reference A1. The following steps explain how you can navigate in an Excel worksheet:

1. Place your mouse pointer over cell D5 and left click.
2. Check to make sure column letter D and row number 5 are highlighted, as shown in Figure 1.4.

Note: Your highlighted column letter and row number may be different than figure shown.

1. Move the mouse pointer to cell A1.
2. Click and hold the left mouse button and drag the mouse pointer back to cell D5.
3. Release the left mouse button. You should see several cells highlighted, as shown in Figure 1.5.

This is referred to as a cell range and is documented as follows: A1:D5. Any two cell locations separated by a colon are known as a cell range. The first cell is the top left corner of the range, and the second cell is the lower right corner of the range.

1. At the bottom of the screen, you’ll see worksheets. Depending on your version of Excel, you will see either three as displayed above or just one. If you only have one sheet, click the “Insert Worksheet” to add a worksheet. Depending on your version, you instead may have a + sign; a click on the + adds an additional worksheet as well. This is how you open or add a worksheet within a workbook. Add another worksheet so that you now have three sheets displaying here.
2. Click the Sheet1 worksheet tab at the bottom of the worksheet to return to the worksheet shown in Figure 1.5.

Keyboard Shortcuts

Basic Worksheet Navigation

• Use the arrow keys on your keyboard to activate cells on the worksheet.
• Hold the SHIFT key and press the arrow keys on your keyboard to highlight a range of cells in a worksheet.
• Hold the CTRL key while pressing the PAGE DOWN or PAGE UP keys to open other worksheets in a workbook.

Excel’s features and commands are found in the Ribbon, which is the upper area of the Excel screen that contains several tabs running across the top. Each tab provides access to a different set of Excel commands. Figure 1.6 shows the commands available in the Home tab of the Ribbon. Table 1.1 “Command Overview for Each Tab of the Ribbon” provides an overview of the commands that are found in each tab of the Ribbon.

Table 1.1 Command Overview for Each Tab of the Ribbon

The Ribbon shown in Figure 1.6 is full, or maximized. The benefit of having a full Ribbon is that the commands are always visible while you are developing a worksheet. However, depending on the screen dimensions of your computer, you may find that the Ribbon takes up too much vertical space on your worksheet. If this is the case, you can minimize the Ribbon by clicking the button shown in Figure 1.6. When minimized, the Ribbon will show only the tabs and not the command buttons. When you click on a tab, the command buttons will appear until you select a command or click anywhere on your worksheet.

Keyboard Shortcuts

Minimizing or Maximizing the Ribbon

• Hold down the CTRL key and press the F1 key.
• Hold down the CTRL key and press the F1 key again to maximize the Ribbon.

The Quick Access Toolbar is found at the upper left side of the Excel screen above the Ribbon, as shown in Figure 1.7. This area provides access to the most frequently used commands, such as Save and Undo. You also can customize the Quick Access Toolbar by adding commands that you use on a regular basis. By placing these commands in the Quick Access Toolbar, you do not have to navigate through the Ribbon to find them. To customize the Quick Access Toolbar, click the down arrow as shown in Figure 1.7. This will open a menu of commands that you can add to the Quick Access Toolbar. If you do not see the command you are looking for on the list, select the More Commands option.

In addition to the Ribbon and Quick Access Toolbar, you can also access commands by right clicking anywhere on the worksheet. Figure 1.8 shows an example of the commands available in the right-click menu.

The File tab is also known as the Backstage view of the workbook. It contains a variety of features and commands related to the workbook that is currently open, new workbooks, or workbooks stored in other locations on your computer or network. Figure 1.9 shows the options available in the File tab or Backstage view. To leave the Backstage view and return to the worksheet, click the arrow in the upper left-hand corner as shown below.

Included in the File tab are the default settings for the Excel application that can be accessed and modified by clicking the Options button. Figure 1.10 shows the Excel Options window, which gives you access to settings such as the default font style, font size, and the number of worksheets that appear in new workbooks.

Once you create a new workbook, you will need to change the file name and choose a location on your computer or network to save that file. It is important to remember where you save this workbook on your computer or network as you will be using this file in the Section 1.2 “Entering, Editing, and Managing Data” to construct the workbook shown in Figure 1.1. The process of saving can be different with different versions of Excel. Please be sure you follow the steps for the version of Excel you are using. The following steps explain how to save a new workbook and assign it a file name.
