AutoHotkey Tip of the Week: The Eval() Function for Hotkey Math Calculations and Text Manipulation

The Classic Eval() Function Solves Problems You Didn’t Even Know You Had by Calculating and Resolving AutoHotkey Functions and Expressions Found in Text Strings!

When I work on particular AutoHotkey solutions, often I find myself in the middle of a treasure hunt—picking up hidden gems along the way. Although operative for years, I didn’t know these valuable tools existed until I went searching for answers to a seemingly unrelated problem.

EvalfunctionMsgBox2For example, the simple question about capitalizing sentences led me to the RegExHotstrings() function discussed last time. As I dug deeper into the math-side of dynamic Hotstrings, I discovered the Eval() function. While many old AutoHotkey hands have employed the Eval() function for years, I didn’t understand its power until I used it in the investigation. (Even now the Eval() function does way more than I comprehend. I’ve only scratched the surface of its capabilities.) Continue reading

AutoHotkey Tip of the Week: Dynamic Regular Expressions (RegEx) for Math Calculating Hotstrings

An AutoHotkey Classic, the Dynamic Hotstrings() Function Makes Instant RegEx Replacements Possible—Now, You Can Do Math with Your Hotstrings!

Anyone who reads my blog on a routine basis knows how I love Regular Expressions (RegEx). They make feasible all kinds of capabilities not practical by any other method. While not necessarily easy for a beginner to grasp, RegEx provides a mechanism for matching text when you don’t know exactly which characters you need (wildcards). (That’s why I wrote the book A Beginner’s Guide to Using Regular Expressions in AutoHotkey.) Although you may encounter a bit of a learning curve, RegEx gives you the ability to accomplish some pretty fancy tasks. This time I plan to demonstrate a couple of Hotstring techniques that might amaze you—they did me! Continue reading

AutoHotkey Tip of the Week: Quick Menu for Activating Open Windows

With a Few Modifications, the WindowList.ahk Script Pops Up a Menu of Open Windows for Quick Activation—Plus, How to Detect When a Windows Opens or Closes

I originally used the WindowList.ahk script as a demonstration of how to use the GUI DropDownList control as a list of selection options for activating open windows (included in the Digging Deeper Into AutoHotkey book). Once, while testing someone’s script, it proved very useful. I could not find the GUI window generated by the code. The script had placed the target window somewhere off the screen. The scriptwriter originally used a second monitor—which I didn’t have. The WindowList.ahk script moved the window back into my view.

As I reviewed the script, I realized that building a pop-up menu of open windows could serve a purpose similar to the QuickLinks.ahk script—except, rather than launching apps and Web sites, the menu would activate open windows. Now, that’s something that I can use!

I often keep numerous windows open simultaneously. Generally, I locate a window by hovering over the Windows Taskbar then selecting the image which looks right. It takes a second for the thumbnails to appear, then hovering over each helps me make my selection. But what if I could maintain a menu of all open Windows available in a menu for instant activation?

AutoHotkey Tip of the Week: Save Time with CodeQuickTester for Testing and Modifying Scripts

Stop Creating Temporary Files to Check Out the New Scripts You Find on the Web—CodeQuickTester Directly Runs AutoHotkey Code without Saving

Since I consider educating motivated users about how to write and implement AutoHotkey scripts my primary purpose in life, I rarely recommend specific “user-friendly” AutoHotkey tools. Although they make scripting simpler, easy-to-use programming apps often interfere with a person’s understanding of the inner workings and hidden mechanism of AutoHotkey.

Don’t misunderstand me. I’m not against anyone using any tools that make life easier but my job is to teach how to get it done—not deliver canned, finished products. That’s why I rarely review other AutoHotkey scripts. However, every once in a while, I find an AutoHotkey app (such as Ryan’s RegExTester) which enhances understanding while making the coding process a little easier. CodeQuickTester by GeekDude falls into this category. Continue reading

How to Send E-mail Directly from an AutoHotkey Script

Using Windows CDO COM, You Can Send E-mail Without Opening Your E-mail Program

RobotEmailCartoonIn my last blog, I wrote a short script for extracting data from a Web page without using a Web browser (“Quick and Dirty Web Data Extraction Script“). As a demonstration, I showed how to quickly download and cull a daily horoscope from an astrology site for display in a MsgBox window. It occurred to me that rather than using a Hotkey each time I wanted to view my horoscope, I would prefer to receive it each morning in an e-mail. That way I could set up the script to run automatically and push the data to me at the same time every day. Plus, I can view an e-mail on any device (e.g. smartphone, tablet, or non-Windows computer) without any special programming. This requires sending an e-mail via an AutoHotkey script.

Calculating Timespans in Years, Months, Days in AutoHotkey, Part 2 (Understanding the HowLong() Function)

Taking a Close Look at the HowLong() Function for Calculating Years, Months, and Days

In this blog, I discuss in its entirety the most recent AutoHotkey code for the HowLongYearsMonthsDays.ahk script (introduced in my last blog). I’ve broken it up into snippets in order to explain the purpose of each piece. To get a complete copy of the script check out HowLongYearsMonthsDays.ahk at the “ComputorEdge Free AutoHotkey Scripts” page or for a barebones version (without comments and inactive code) see “Function Calculating Timespan in Years, Months, and Days” at the AutoHotkey Forum. This blog reviews the nuts and bolts of calculating the timespan between two dates.

Build Your Own Dream Thesaurus Word Replacement Tool (AutoHotkey Web Application)

How to Use the Web to Feed Data to Your AutoHotkey Application—A Pop-up Menu to Replace Boring Words in Your Documents

Synonym Page
I highlight any word and hit the CTRL+L Hotkey combination. AutoHotkey downloads the code from the target Web page and parses the synonyms using RegEx—placing each in a pop-up menu. Click on any item and AutoHotkey replaces the selected word in any document or field open for text editing. In the example, the menu lists possible replacements for the word •PAGE—the first item in the menu. Click •PAGE to open Thesaurus.com at the target location.

I immediately added this short AutoHotkey script to my primary toolbox. It immediately provides me access to a list of alternative words in menu form (shown at right). Click on one of the entries and it instantly replaces the previously highlighted word. The apps beauty lies in the fact that I can utilize the Web for the database of synonyms. The script extracts the menu items directly from a Theraurus.com Web page without opening my Web browser or processing any of the code—no ads. For writers and editors (or anyone who wants to expand their vocabulary), this one script provides enough incentive to plunge into regularly employing the free AutoHotkey Windows utility language.

If Theraurus.com ever notices, I suppose this script may not make the owners of the site very happy. Any revenue they derive comes from the advertising. My app ignores all of it. They could change the formatting of the page, but then I would adjust the Regular Expression I use to extract the data. They might make an attempt to block my efforts, but I guess any such blocking technique would also block regular users. They could block my IP, but that would be a lot of work for just one person. (I would simply switch to another site offering synonyms.) In any case, I plan to continue using this AutoHotkey script until it stops working—for whatever reason. Then, I’ll fix it.

This Windows Trick Works in Vista, Windows 7, 8, and 10
