Batchography: Converting numbers to characters (or the CHR() function)

In various programming languages, you might sometimes need to convert numbers to characters. In simple terms, each character you see has a numerical representation. The ASCII table  shows the numbers of each character and its corresponding glyph.

Converting numbers to their corresponding characters would be useful to generate a random string for instance. The first step to generating a random string is to generate random numbers between 65 and 90 (upper case ‘A’ to upper case ‘Z’) or between 97 and 122 (lower case ‘a’ to lower case ‘z’).

While the Batch language is pretty primitive, you would be surprised how many things you can do with it. In the Batchography book, I cover various topics that would bring your Batch programming skills to the next level.

Batchography: How to do a “switch/case” in Batch files

You have found this blog post because you are wondering if there is a way to express a “switch/case” logic in Batch files.

The short answer is NO, not exactly. However, there are ways to achieve the same in Batch files.

In the Batchography book, I explain in details the “switch/case” construct, but in this blog post I will illustrate this mechanism briefly. For more advanced Batch scripting topics, please grab a copy of the Batchography book.

Batchography: How to check if your Batch file script is running as an Administrator

In chapter 4 of the Batchography book, I illustrate 3 methods that you can use to check if your Batch file script is running as an Administrator.

In this blog post, I will share with you the method entitled “Using known commands that fail to run without elevated privileges” from the book.

The idea behind this method is to run commands that are known to fail and return a non-zero error code if they are not executed with administrative privilege.

The Batch script would then check the return code and act accordingly:

@echo off

net session >nul 2>&1

if %errorlevel% neq 0 (
  echo Requires administrative privilege.
  goto :eof
)

echo Script starts here...
