vim: cleaning up mixed indents

Thanks to the wiki for this.  If you run across a file that mixes tabs and spaces (ewww!), set the tab settings the way you want (e.g., ts=4 sts=4 sw=4 et ai) and run


to convert all the tabs to the right number of spaces.  This takes tab stops into account, which :%s/^I/    /g won’t.

This replaces what I used to do, which was /^I s<Tab><Esc> followed by a whole lot of n.n.n.n.n.n.n.n. … .  One command is much better 🙂 .  I’m not even going to try to count the keystroke savings on my current project (pym, a preprocessor written in Python).

Filename searching in Explorer – Windows 8.1 Enterprise

Some tips for filename searches in the “Search” box in an Explorer window in Windows 8.1 Enterprise.  I just found these out by trial and error.

  • You can specify “filename:” rather than “system.filename:” to search filenames.
  • The text after “filename:” will, by default, only match at the beginning of a word within the filename.
  • “filename:*foo” will search for foo, whether at the beginning of a word within the filename or not.
  • As far as I can tell, search filenames get an implicit “*” added on the end unless you specify otherwise.
  • To search for a word in the name and also the extension, use “filename:foo AND ext” where DOS would have required “*foo*.ext”.  I tried “filename:*foo*.ext” and “filename:(foo AND ext)” without success.  Remember, the “AND” has to be uppercase!

Happy searching!

Boolean searching in Microsoft Outlook

Turns out it can be done!  This article from Slipstick Systems shows you how to enable the Query Builder in the Advanced Find dialog box.

I was trying to search for two partial words in the Subject of my emails in Outlook 2013.  Turns out the “Search” box in the folder view only finds matches at the start of a word.  The Advanced Search dialog box, Advanced pane, looked promising.  However, when I added multiple criteria, I think it was ORing them rather than ANDing.  Not sure, but I do know that I added two separate Subject terms and not all the results had both terms in their Subject fields.

With Query Builder, each search criterion I entered was automatically added to an AND group, and the search results were what I expected.  Now if only you didn’t have to tweak the registry to enable this incredibly useful feature…

Breaking infinite loops in VBA

I do a lot of Visual Basic for Applications (VBA) development in Microsoft Office. Any program can get stuck in an infinite loop, and when my VBA programs have it has always meant data loss. The Internet to the rescue, as of not quite a month ago!

To break VBA code execution, at least in Office 2013, hit Ctrl+Scroll Lock.  Obvious, right? 😉

Huge thanks to MSDN user povidla, who posted this solution in the MSDN forums.  Povidla, if you’re reading this, please comment so I can thank you directly!

Edit I have found that, in some situations, this doesn’t work unless there is a DoEvents call to catch the Ctrl+ScrLk.  If you have a loop that might be infinite, sticking a DoEvents in it is probably a good practice.

Greetings to Stack Overflow users!  I keep hoping that Povidla will find this page.  If you happen to know who Povidla is, please pass along a thank you from me.  Regardless, thanks for reading!

How not to waste disk bandwidth

In the Windows 7 search boxkeywords are case-insensitive, but Boolean operators are case-sensitive.  Typing

System.FileName:~=".doc" AND datemodified:‎1/‎5/‎2016

works fine. Typing

System.FileName:~=".doc" and datemodified:‎1/‎5/‎2016

doesn’t given an error message or a warning — it just burns a lot of disk searching and finding nothing. Live and learn!
