only asking for trouble if you use variable names 255 characters long. To make variable names more readable, programmers often use mixed case (for example, InterestRate) or the underscore character (interest_rate). Don’t wear yourself out typing the entire name of a variable. Just type the first two or three characters and then hit Control+Space. The VBE will either complete the entry for you or — if the choice is ambiguous — show you a pick list to select from. In fact, this slick trick works with reserved words too. VBA has many reserved words that you can’t use for variable names or pro- cedure names. These include words such as Sub, Dim, With, End, and For. If you attempt to use one of these words as a variable, you may get a compile error (your code won’t run). So, if an assignment statement produces an error message, double-check and make sure that the variable name isn’t a reserved word.
✓ Enable all macros: Let all macros run with no warnings. This option is not recommended because potentially dangerous code can be executed. Consider this scenario: You spend a week writing a killer VBA program that will revolutionize your company. You test it thoroughly and then send it to your boss. He calls you into his office and claims that your macro doesn’t do anything at all. What’s going on? Chances are, your boss’s security setting does not allow macros to run. Or maybe he chose to go along with Microsoft’s default suggestion and disable the macros when he opened the file.
So what’s the point of this mini history lesson? If you plan to distribute your Excel/VBA files to other users, it’s vitally important that you understand which version of Excel they use. People using an older version won’t be able to take advantage of features introduced in later versions. For example, if you write VBA code that references cell XFD1048576 (the last cell in a workbook) , those who use an earlier version will get an error because pre-Excel 2007 worksheets only had 65,536 rows and 255 columns (the last cell is IV65536). Excel 2007 also has some new objects, methods, and properties. If you use these in your code, users with an older version of Excel will get an error when they run your macro — and you’ll get the blame.
are benign and malicious. Thus it was required to collect known benign and malicious samples to construct a training set. Malicious samples can be collected from various sources online. Here, malicious samples were exclusively collected from the website, malshare.com. This website exposes an API to end-users and maintains good classification of samples by YARA rules created by community members. Once samples were downloaded, they were verified as malicious by scanning with VirusTotal and any samples not deemed malicious by at least three vendors were discarded. Subsequent manual inspection of each sample was carried out to ensure its malicious nature. Collection of benign samples was more challenging. To create a benign training set, various VBA tutorial websites offering example macros were consulted. In addition, Google searches for filetype:doc and filetype:xls with keywords such as VBA and macros, revealed more samples. Again, this set was further validated by scanning each sample on VirusTotal and excluding any sample that deemed malicious by any detector. Subsequent manual inspection of each sample ensured it was indeed benign. From each sample in the training set, all features are extracted and used to train a classifier. Once trained, the model is serialized to a file on disk. This enables the persistence of already trained models, and allows one to swap with ease between classifier models.

Creates a special hidden workbook that opens whenever Excel is run on your local machine. The macros stored here are available whenever you use Excel regardless of which workbook you are in. If you store your macros here, they will not be available to others if you share a workbook. You will need to add the macro to the workbook you are sharing in order for it to be available to others.
This paper has described how SAS and Excel can be used together to produce listings and patient summaries. The programming is kept to a minimum by preprocessing the data in SAS and using Excel for the layout of the data. Using Excel for this purpose shifts the display requirements to the user thereby reducing programming time and increasing user satisfaction.
Goal Setting After watching the Goal Setting video, start a new Excel workbook and save it as e01b4Goals_ LastFirst. List three descriptive goals in column A relating to your schoolwork and degree completion. For example, maybe you usually study three hours a week for your algebra class, and you want to increase your study time by 20%. Enter Algebra homework & study time (hours) in column A, 3 in column B, the percentage change in column C, and create a for- mula that calculates the total goal in column D. Adjust column widths as needed.
Page breaks allow you to control where one page ends and the next one starts. Excel will decide where the page breaks depending on how much information you have typed in and the size of the paper plus the margins. However, if you want to print your spreadsheet out in a particular way, you can set the page breaks up yourself.
You may need to use the Save As feature when you need to save a workbook under a different name or to save it for earlier versions of Excel. Remember that older versions of Excel will not be able to open an Excel 2007 worksheet unless you save it as an Excel 97-2003 Format. To use the Save As feature:
The first tab in the Chart Options window is the Titles tab. Excel will automatically use the name of the data series as the title of the graph. Descriptive names should be entered for the chart title and the x- axis and y-axis values. For example, a good title name might be “Distance vs Time of Glider on Track” with the x-axis named “Time (s)” and the y-axis named “Distance (m)”. Notice that the units for each axis are included in the name. If they weren’t, someone looking at it would have no idea of the units of the graph. Even if it seems redundant, always include the units!
C opying an original formula that you build to all the cells in the worksheet that per- form the same type of computation is one of the more common tasks you perform as part of creating a new spreadsheet. Despite this fact, understanding just how Excel goes about adjusting the cell references when you copy a formula is not widespread among new users. The exercises in this chapter give you a chance to practice copying formulas using all the different types of cell references. In addition, you practice assign- ing range names to the cells that are referenced to in spreadsheet formulas, creating array formulas that do away with the need for making formula copies, as well as tracing and eliminating the source of errors that have spread across the workbook.
Dates can be extended as a series by day, weekday, month or year. Excel requires that dates are entered in a cell with either a forward slash or a hyphen (1/12/05 or 1-12-05) even if the date is then formatted to appear differently; e.g.1.12.05. You cannot enter a date using full points or spaces. AutoFill also recognises days of the week and months of the year in abbreviated form (first three letters) or spelled out in full.
Spreadsheet packages also come with powerful built-in programming languages, making their versatility almost limitless. The best part about spreadsheets is that the initial learning curve is very short! We use Microsoft Excel 2000 for all demonstrations in this manual, but due to the standardization in today’s spreadsheets, one should be able to apply this material to almost any spreadsheet package. Throughout this manual, spreadsheet and PC terminology will be used. In Figure 1, the typical window one sees is displayed with many of the names we use in this manual.
Excel will probably always be the ultimate program for creating formulas but SharePoint can also use formulas as well. When working in a SharePoint list it is easy for someone who has knowledge of using formulas in Excel to start creating calculated columns in SharePoint. The example below shows an IF statement being used to apply a 20% discount if a total is over 100 or charge full price if the total is less than 100.
A common type of spreadsheet contains information in a structured list, also known as a table. A table is a rectangular range of data that usually has a row of text headings to describe the contents of each column. Excel’s table feature makes common tasks much easier — and a lot better looking. More importantly, the table features may help eliminate some common errors. This chapter is a basic introduction to Excel tables. As always, I urge you to just dig in and experi- ment with the various table-related commands. You may be surprised by what you can accomplish with just a few mouse clicks.
Excel’s Text functions offer a wide variety of methods for searching and manipulating text entries in a spreadsheet. These functions include the CONCATENATE function for joining together strings of text (specified as its text arguments) — just like the & (amper- sand) operator in the handmade formulas you constructed in Exercise 13-1 — and, per- haps even more useful to most, the UPPER, LOWER, and PROPER functions for changing the capitalization of text entries in the spreadsheet. (Most of the other Text functions are seldom required outside of macros and specialized VBAprogramming applications.) Figure 13-1 shows you an example of a spreadsheet that is in desperate need of the PROPER function, which changes the case of the text specified as its sole argument to Title case, where only the first letter in each word is uppercase.
