winapi – Best way to do non-flickering, segmented graphics updates in Delphi? – Stack Overflow

Posted by jpluimers on 2011/07/05

Recently, Jon Lennart Aasenden (of Surface Library fame) asked a nice winapi – Best way to do non-flickering, segmented graphics updates in Delphi question on StackOverflow.

Though the question is marked Delphi, the boundaries and solution very generic, and apply to any graphics library or GUI you develop: Windows, Mac, iOS, et cetera:

  • Avoid double buffering when using GUI connections
  • Draw only what you need
  • Avoid redrawing whenever possible (for instance by letting the OS perform scrolling for you)

The importance of static links on the web: many (really) old links still work

Posted by jpluimers on 2011/06/30

Doing a re-haul of a Delphi project from almost 15 years ago, and some modifications a few year later, I came across a list of favourites I used back then.

It also reminded me when beginning that project, there was no Google Search; you had Yahoo Search, HotBot and later on Northern Light, but AltaVista was the best.
Finding your way around was much harder, but luckily later on Google Search was there :)

So here is a sample of how static the web is:

Few suffer from link rot: I was pretty amazed that most of the links still work!

Weaving: Source code, IL, ByteCode, Native

Posted by jpluimers on 2011/06/28

Weaving extends your program adding new functionality.

It can be at different levels for difference purposes (AOP, Debugging, Automated Testing, etc).

This .net – What is IL Weaving? question on StackOverflow contains a few pointers to interesting reading material.

Delphi and COBOL syntax highlighters

Posted by jpluimers on 2011/06/21

I’ve been working on a project that uses both COBOL and Delphi.

For documentation purposes, Syntax Highlighted code makes your code so much easier to read.

Delphi has GExperts for source code export (in either HTML or RTF), but it took me a while to find a good syntax highlighter for COBOL.

I finally found a COBOL syntax highighter at tohtml.com: it exports to HTML.

I’m glad I found that site, as they have a ton of syntax highlighters, divided into groups.

Quite amusing to see COBOL classified as ‘rare’ (given that it has one of the largest code bases in the world).

SVN tree to source code of Marco Cantu’s Delphi Books

Posted by jpluimers on 2011/06/09

If you love the Delphi books by Marco Cantu as much as I do, then you certainly will love that Marco has created a public SVN repository at code.marcocantu.com containing all the samples of his Delphi 6, 7, 2007, 2009, 2010 and XE books.

Way to go Marco!

GExperts version 1.35 was released on June 5th, 2011

Posted by jpluimers on 2011/06/08

Earlier this week, the new GExperts 1.35 Release got published: a free set of expert extensions supporting Delphi 6 through XE.

It is an incremental release has a few new features of which I like the new subgroup support in the Grep Search extensions most.

Now hopefully, Thomas Müller will release an experimental GExperts build of version 1.35 soon: his experimental builds integrate a source code formatter that works across many Delphi versions and often formats better than the one included in Delphi 2010 and up.

Delphi sorcery – great new blog by Stefan Glienke: DataBinding, MEF, Lamda Expressions and more

Posted by jpluimers on 2011/06/07

I just came across the great new Delphi sorcery blog by Stefan Glienke from Soest, NRW, Germany.

He uses some cool new features recently introduced into Delphi for new ways of DataBinding, Yield-Return, Delphi Lambda Expressions, Delphi Dependency Injection with MEF and more.

Sample code is at his Delphi Sorcery Google Project.

I hoped that somebody would do all that, as this shows the real power of what Delphi can do.

Now it’s there for

Delphi Win32 talking to .net – Different WSDL ASMX,WCF web-services – Stack Overflow

Posted by jpluimers on 2011/05/31

An interesting question on Stackoverflow.com: .net – Different WSDL ASMX,WCF web-services – Stack Overflow.

The answer is simple when you know it: flatten the WSDL that comes from WCF.

Note that Delphi Win32 is not the only client having these issues, as Elton Stoneman shows on his blog and the WCFExtras toolkit for WCF that allows for single WSDL export.

Tortoise SVN Global Ignore Pattern for Delphi and Visual Studio

Posted by jpluimers on 2011/04/26

Since I use (among others) both Visual Studio and Delphi, I changed the Tortoise Global Ignore Pattern to be this:

Debug lib *.identcache *.local *bin *obj RECYCLER Bin *.user *.suo *.dcu __history ModelSupport_* *.rsm thumbs.db *.bak *.~* __recovery *.tvsconfig *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ #*# .#* .*.swp .DS_Store

The bold portion is what I changed when compared to the original one:

*.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ #*# .#* .*.swp .DS_Store

Input from [WayBack] Tortoise SVN Global Ignore Pattern for Visual Studio (which also included some of the Delphi patterns), [WayBack] this Stackoverflow question (that indicated the patterns are case sensitive) and [WayBack] Shawn Oster | TortoiseSVN global ignore pattern for Visual Studio and Delphi.

–jeroen

PS: Added __recovery as Delphi 10.* started to use that for recovery files, which – unlike __history  is not documented, see [WayBack] What is the __recovery folder ? In C++ Seattle 10 Professional running under Win 7 I now get a folder called __recovery.
