Swapping Variable Values (Beginning AutoHotkey Tip)

Rather Than Rewriting Code, Sometimes You’ll Find It Easier to Swap Variable Values

You may not need to use this technique very often but when you do, it can save you a lot of time.

Calculating Years, Months, Days Problem

I wrote the HowLong(FromDay,ToDay) function to calculate the difference between two dates in years, months, and days. The way the function operates it starts at the first date (FromDay) and works its way forward to the second date (ToDay). If the first date occurs after the second date, the function yields bad results.

HowLongOriginally, I added a trap to notify the user when the first date occurred after the second date—offering an opportunity to try again. However, I eventually realized that I only needed to reverse order of the dates to yield the right answer. Rather than rewriting a ton of code to create a backward-looking function, I left the original logic untouched by swapping the two date values when in reverse chronological order. Continue reading

Add Emoji Characters to Any Windows Document (AutoHotkey Hotstrings)

Why Search Through Pop-up Tools When You Can Directly Enter Any Emoji into Your Documents, E-Mails, and Web Editing Windows with AutoHotkey?

“I went to the 🏖 on a 🌞day. The 🌞 was so 🔆 that I needed to wear 🕶. I was lucky enough to see a 👩 in a 👙🖐 to me. I saw 🌊s, ⛵s, 🌈s, and a 🦄. Maybe, I had a few too many 🍻s.” 🙄

Years ago I wrote about an AutoHotkey app called WinCompose: a Robust Compose Key for Windows which adds special characters to any Windows document or Web editing field. It appeared to use the Input command in conjunction with a “Compose” key to enter memorable keystrokes for inserting special characters. WinCompose has since converted to a different programming language and added emoji support. Similar to emoticons, emojis add special cartoon-like pictograms to your documents. Unlike emoticons, many programs recognize emojis—as long as the software includes UTF-8 support. Continue reading

A Trick for Inserting Next Friday’s Date into Any Document (AutoHotkey Tip)

An AutoHotkey Technique for Determining Date for Any Coming Day of the Week, Plus a Pop-up for Picking Future Weekdays

“Do You Know Next Friday’s Date?”

We record upcoming events on our monthly calendars, but we live one week at a time. Most people work Monday through Friday and relax on Saturday and Sunday. If someone gives us a date for an occasion, we ask, “What day is that?”—meaning “Give me the day of the week.”

A Beginner’s Guide to Understanding AutoHotkey If Statements

It Can Get Pretty Confusing When Considering Which AutoHotkey If Conditional to Use

Occasionally, when updating or modifying a script I run into a problem where an If conditional just stops working. At first, I experience the usual confusion, but, eventually, it occurs to me to enclose the subject of the conditional in parentheses. The code starts working again. How does this happen? Continue reading

Swapping Dyslexic Letters (A Favorite AutoHotkey Trick)

Sometimes the Little Things Remind Me How Much I Like AutoHotkey

As I worked on one of my blogs, I accidentally transposed two letters (probably “form” for “from” or vice versa). I placed the cursor between the errant letters and hit the R key while holding down ALT. The two characters exchanged position. Pleased with myself, I decided to highlight the letter-swapping Hotkey combination in this blog as one of my favorites.

Accessing Web Pages (AutoHotkey Tips)

Find a Consistent Relationship in URLs to Redirect Web Pages

A while back I wrote a script which accessed the AutoHotkey online documentation quickly bringing up information about commands and variables. It took advantage of a hidden index in AutoHotkey.com which loaded key pages. However, as happened at the time, relying upon that index does not guarantee access. As with any Web page, things change.

The online documentation is currently going through some modifications. Possibly, in preparation for future use with the coming AutoHotkey version 2.0, we see a number of new revisions. With those alterations, the secret index has once again disappeared. That means much of my earlier work no longer functions as designed. I’ve decided to completely redo my AutoHotkey reference app with the following goals:

  1. Drop reliance on any hidden index to quickly return AutoHotkey command and variable information.
  2. Add simultaneously support for both AutoHotkey V1.1 commands and the parallel V2.0 functions.
  3. Add support for locating changes in V2.0 not directly correlating with V1.1 commands.
