Using Object Pointers in a DataSet TField

TPersistent.com – I have seen code where an object pointer is stored in each row of a TDataSet, and referenced by code.  So skipping the question of the validity of such code, how do you support X86 and X64 bit code, especially if you use persistent TFields (use Delphi’s Form Designer RAD approach for the UI)? ...

A Hint About Warnings

TPersistent.com – Compiler Hints and Warnings are an important indicator of the quality of the code you are compiling.  It dismays me that I have often seen a ton of compiler warnings on commercial components suites when I compile them.  It makes you question the care taken when writing the code. Compiler Hints and ...

Every Team needs a Goaltender

TPersistent.com – It’s been my experience that just like in sports where you have a goal tender, every development team needs a gate keeper or goal tender for their VCS to ensure nothing gets in that they don’t want.  The role of the gatekeeper in the team is not only to manage the promotion/demotion of ...

EMBT gets a Swift Kick in the Assetts

TPersistent.com – In case you haven’t heard yet, Apple has created a new language meant to be more friendly than Objective C.  They call it Swift, and it is aptly named judging from the benchmarks which show it to be significantly faster than Objective C even though it uses the same run-time and is compiled ...

ReEnabling the GExperts Procedure List (Ctrl +G)

TPersistent.com – If you are like me, you use GExperts in your IDE.  IMHO much of the functionality GExperts offers should be part of the stock IDE.  Once you start using it, there is no going back.  Many thanks to Erik Berry and company for putting all this together and keeping it supported through so many releases ...

MSBuild MSB6003 Work Around

TPersistent.com – One of the QC items not fixed in the XE6 release is 98008, probably because it is still in the Reported state even though it was submitted August 23, 2011. I have previously blogged about the state of QC, so I won’t get into that issue again, suffice to say I hope the QPS initiative continues, ...

XE6 Released with some Interesting Features

TPersistent.com – I attended the webinar today announcing Delphi XE6. It’s been a long road for the EMBT dev team to provide both C++ and Object Pascal support for iOS, Android, OS X, and Windows in the same environment. Kudos to them for accomplishing that feat, and incorporating over 2000 bug fixes into the ...

Using CodeSite to Spot Peformance Optimization Opportunities

TPersistent.com – I have been using CodeSite for a long time now (since v2 days), but I am still continually impressed by the product and it’s capabilities.  If you want to do something with your log data, chances are CodeSite has you covered, you just need to figure out how it is implemented. Today, I wanted ...

How to Avoid Getting Upset with OptSets

TPersistent.com – OptSets are a great thing for using consistent settings across multiple projects and machines (such as a build machine). Although they were introduced in D2009, I have found that there are still issues using them in XE4 which I believe are problems in the software and not my wetware. The first ...

Vote for Me!

TPersistent.com – Actually I am not running for an office of any kind.  I would actually appreciate some votes for my QC items (if that truly counts for anything in terms of prioritization).  Specifically, I would like to see QC # 123768 and 93267 fixed, but feel free to search through all my reports and vote for ...

Out of Memory - Solved!

TPersistent.com – I recently read EMBT’s Delphi RoadMap and was very happy so see that QPS (Quality, Performance, Stability) is item #2 on the Delphi 2014 list.  I certainly hope that these items appear in order of priority.  One of the primary issues I keep hitting is the Out of Memory error, although far less ...

Another Broken Link in the Wall

TPersistent.com – Chris Rolliston recently blogged that the Mobile Pack for Delphi Pro is being discounted 50% until the end of March, so I thought I would check it out.  A percentage  doesn’t tell you anything because retailers sometimes mark up the product so they can discount it by 70% to attract buyers. I ...

An Interface You Can Count On

TPersistent.com – Using refcounted interfaces can be difficult, especially when introducing them into legacy code.  Unfortunately, interfacing is key to breaking dependencies and making code more testable. There are only two approaches I have seen to debugging refcount issues: 1) Create a descendant of ...

UI Design - What Not To Do

TPersistent.com – I would never claim to be a good UI designer.  What I know of design is from personal use.  One principle that applies to both code and UI design is that consistency is king.  I often look to widely used commercial software as models for UI design. Of course, one of the software packages I use most ...

Out of Memory Exception Solved!

TPersistent.com – Compiling project groups even of relatively small projects can generate ‘Out of Memory’ exceptions.  I have been plagued with such errors since upgrading to XE3, and they are sadly still present in XE4.  Reading the newsgroups I have found posts indicating some users are experiencing ...
