CodeSnip v4.0 RC-1: Nasty Duplicate Display Name Bug + Fix

Well, this is embarrassing.

Only a few days after CodeSnip 4 RC 1 became available I've discovered a nasty bug that causes the user interface to crash if more than one snippet has the same display name. The bug also applies to Beta 1 and Beta 2.

It's really nasty for two reasons:

  1. Its easy to trigger the bug. All you have to do is to accept an edit where you have created a display name that duplicates an existing one. Once you've pressed OK its too late. Worse, if you duplicate a snippet CodeSnip automatically duplicates the display name if the snippet has one. Once again pressing OK is all that's needed.
  2. Because the bug is reported as a fatal error, CodeSnip helpfully tries to save the database before terminating. In the case of this bug it usually succeeds, which means the duplicate display name is saved in the database. When CodeSnip is restarted it instantly crashes again because its UI can't display the duplicate display names.

I've rushed out a fix that you can get from SourceForge and from my website. Please download it now if you're using one of the affected editions.

Even if you've already been bitten by the bug all is not lost. Just download and install the fixed version (or any later release) and simply run it. It will be able to load the database, with the duplicate display names, and you hopefully won't have lost any data.

You'd be well advised to backup the database before carrying on (Database > Backup User Database menu option). But you do that anyway don't you!!

Really sorry about this one folks!

The linked download also incorporates another major bug fix.

New String Property Editor Planned For RAD Studio 12 Yukon 🤞

This blog post is based on a pre-release version of the RAD Studio software and it has been written with specific permission by Embarcadero. No feature is committed until the product GA release. It seems I'm getting very excited about multi-line strings of late. My previous post was about multi-line string literals for Delphi  and this time I'm talking about the new multi-line string property editor being slated for the RAD Studio 12 IDE. For more years than I care to remember, I've been frustrated by the inability to enter multi-line strings in the Delphi IDE object inspector. That meant having to resort to code to initialise some multi-line labels. So frustrated was I that I wrote a little property editor of my own ( stringpe ), way back in 2004. It's still around and on GitHub. Here's what it (sometimes) looks like: Yeah, I know this is Vista - I used an old screenshot Sometimes? Well it looked like that until it got installed on DPI aware Delphis, and then it sh

Multi-line String Literals Planned For Delphi 12 Yukon🤞

This blog post is based on a pre-release version of the RAD Studio software and it has been written with specific permission by Embarcadero. No feature is committed until the product GA release. The upcoming new release of RAD Studio 12 Yukon is a major update that's got a new Delphi language features that I've been wanting for years, or perhaps even decades since I first discovered heredocs in PHP. Yep, we're going to get multi-line string literals. This excites me just as much as the earlier introduction of inline var statements, which was a lot! I write a lot of multiline string constants in my code like this: const   S0 = ' Lorem ipsum dolor sit amet, consectetur adipiscing elit.' +         sLineBreak  +        '   Vestibulum eleifend elit id dapibus pulvinar.' +        sLineBreak +        'Suspendisse tincidunt, diam vel dapibus aliquam.'; Miss out one of the closing quotes or + signs and bang, compile failure. Annoying. But now we have multi-l

Call JavaScript in a TWebBrowser and get a result back

Calling a JavaScript function in a TWebBrowser is easy, but getting a return value from it is hard. I've been struggling for ages to find an answer to this, and lots of users have asked. My article " How to call JavaScript functions in a TWebBrowser from Delphi " goes into details. Christian Sciberras suggested a solution that depended on modifying the HTML source to include a hidden input field and modifying the function stores its result in the field. I've wanted a tidier solution that didn't involve changing either the HTML code or the JavaScript function, because we can't always do that. I've now got a solution based on Christian's: Create a hidden input field in the current document with a unique id. Wrap the required function call in JavaScript that calls the function and stores its return value in the input field. Read the value from the input field and return it. It's a bit of a dirty hack, and it only works if the function&#
