Embarcadero has some cool new Delphi iOS technology in the pipeline (via: Xcode – Debug iOS application on device without symbols – Stack Overflow)

Posted by jpluimers on 2012/06/27

Today exactly a month ago, Allen Bauer (Chief Scientist at Embarcadero) asked a really in depth question about debugging the startup sequence of iOS apps on a device not originating from Xcode on Stack Overflow indicating on what Embarcadero is researching.

Last week, he also answered the same question using manual steps for GDB. Not easy, but it works.

For a development tools company, getting your tools to work on a new platform is hard, and in this case it seems exceptionally hard.

I’m really looking forward to see what kind of cool tools come out of this, as the current developemt platform choices (Xcode or MonoTouch) can really use more competition to make it easier for us developers.

Exciting times ahead (:

C# Remove Duplicate Lines From Text File? – Stack Overflow

Posted by jpluimers on 2012/06/27

Recently I had to do a quick removal of duplicate lines in bunch of text files.

A quick search revealed that back in 2009, John Skeet came to the rescue with a couple of examples (:

Stefan Glienke on Delphi generics: Implementing List Enumerator OfType in Delphi – Stack Overflow

Posted by jpluimers on 2012/06/26

Stefan Glienke posted a nice StackOverflow answer on some things to watch for when using Delphi Generics to implement an IEnumerator of type for a generic usage that works better than the stock one.

Repeating characters into strings in C# and Delphi (via: .net – Best way to repeat a character in C# – Stack Overflow)

Posted by jpluimers on 2012/06/26

Switching back and forth between mainly Delphi and C#, sometimes it is hard to remember which idiom works best in each environment.

Recently, I had to dupe a lot of tab characters for some Tab-Delimited interface to an archaic system.

I remembered the Delphi idiom: use the DupeString function as about Delphi explains (yes, I know: it dupes more than just characters).

In C#, these work best for me:

Small code sample of the first way (thanks CMS):

static string Tabs(int n)
{
    return new String('\t', n);
}

Oh BTW: I have reduced my StackOverflow presence. It looks like the success of StackOverflow made them instantiate many moderators. A lot of those moderators work under the mantra “we follow the rules strictly, and favour punishment over encouragement” (some  even talk about “changing heritage“). That’s a real pity, as I see a lot of StackOverflow users get scared by the very active downvoting, question/answer closing and even deletion of material that is in essence valuable, if it were edited up a bit. Deleting content is always bad, as it increases the link rot that StackOverflow are trying to prevent in questions/answers as per their FAQ. Links are the foundation of the web.

Alas, devoting real attention to the quality of StackOverflow requires putting real energy in it, which for some of the moderators seems to be too much to ask.

Delphi: [##] numbers in DFM files determine order of subcomponents (via: Strange [number]s in Delphi DFM files – origin and necessity? – Stack Overflow)

Posted by jpluimers on 2012/06/21

Another interesting SO thread that explains [##] numbers in DFM files.

They are used to determine the order of subcomponents when using form/frame inheritance.

.NET/C# – WinForms splash screen research material

Posted by jpluimers on 2012/06/21

I’m in the midst of converting a suite of WinForms C# projects from a range of .NET versions (1.x till 3.x) to 4 totalling some million lines of code.

One of the problems is that some people hacked together some splash screen stuff using multi-threading, doing all sorts of things that was forbidden in .NET 1 (and broke in .NET 2+).

On my research list for getting this to work:

  1. Mahin Gupta | Winforms splash screen – Great work by Tom. which is an update of
  2. A Pretty Good Splash Screen in C# – CodeProject.

Direct Visual Studio 2012 RC and Windows 8 Release Preview ISO download URLs

Posted by jpluimers on 2012/06/20

Somehow many software vendors seem to make it a sport to make it hard to get download URLs.

So here is a bunch of direct download URLs for the (almost new <g>) Visual Studio 2012 RC (formerly and internally known as Visual Studio 11).

There are both ISO files (big, but convenient for offline installation).

Web installers (depending on the choose install options, the total download can be a lot less than the complete ISO, but your system needs to be online during the full installation process).

You can find similar Windows 8 Release Preview download links here (they were distilled from the official download page, which now gives a 404 because of the atdmt link redirect is broken).

I use the x64 and x86 shortcuts for the x64 and x86 ISO links.

The Windows 8 Release Preview Upgrade Assistant also comes in handy.

The above links give a sustained transfer rate here of at least 3 megabit/second.

Strong name for Interop.Scripting – .NET Framework

Posted by jpluimers on 2012/06/20

So I won’t forget:

I was trying to generate from the interop.scripting.dll which I guess was the automatically generated dll without strong naming. A wrapperof a wrapper apperently doesnt work.
The following did work:

tlbimp.exe C:\WINDOWS\system32\scrrun.dll /keyfile:..\nameHere.snk /out:Interop.Scripting.StrongNamed.dll

The suite of .NET projects I’m refactoring relies in part on scripting in the Microsoft Script Runtime because the original was build by people bringing their COM love from the VB6 world into the .NET world.

I don’t see COM as the first class citizen it was in the VB6 era. On the other hand, COM and ActiveX play an important role in the .NET world. Sometimes I regret that, as dealing with COM is hard.

Some consider COM a first class citizen in .NET as it was in VB6, especially after the dynamic keyword was added in C# 4.0. The variant type available since Delphi 2 since 1996 does more or less the same as dynamic keyword in C#. I know how Anders Heijlsberg disliked the Delphi Variant support of COM. But COM is what the market wanted in 1996, and that seems true until today.

But I digress.

At least parts of the .NET code needs to become strongly named, so I’m hesitating:

  1. kick out the COM stuff – and verify through unit tests that the encompassing code still works – or
  2. generate a strongly named COM Interop Wrapper as described above.

Not sure yet.

Opinions anyone?

Anyway, I’m expecting a few problems here and there, so I’ll be using the CLR Interop Tools like the P/Invoke Interop Assistant and Type Library Importer in Managed Code where needed.

TFS – Undelete File or Folder – brilliantly easy from the Visual Studio IDE: just enable “Show deleted items in the Source Control Explorer”

Posted by jpluimers on 2012/06/19

Never knew it was so brilliantly easy to undelete files from TFS: you can do it in Visual Studio, by enabling “Show deleted items in the Source Control Explorer” in the settings.

Just look at TFS – Undelete File or Folder for the screen shots.

Not sure in which Visual Studio version this got introduced, but it works in VS 2010 and up.

Delphi: interesting SO question + answer on using AllocateHWND to route TThread messages to a message handler in a TObject descendant (via: delphi – Custom Messages in Non-Windowed Classes – need a default handler? – Stack Overflow)

Posted by jpluimers on 2012/06/19

The delphi – Custom Messages in Non-Windowed Classes – need a default handler? – Stack Overflow thread on SO is very interesting.

It explains how to use AllocateHWND to route messages for a TThread into a message handler of an object instance.
