XSD/XML Schemas: resolving `Namespace ” is not available to be referenced in this schema` (via: StackOverflow)

Posted by jpluimers on 2013/09/01

While working on my Delphi: First try on an XSD for .groupproj files, I bumped into an error `Namespace ” is not available to be referenced in this schema`.

I added a targetNamespace attribute to the GroupProj.xsd so the .grouproj files would use the right namespace.

That resulted into two funny errors:

  1. Namespace ” is not available to be referenced in this schema.
    Visual Studio (which I normally use for editing XSD) would only throw this error on these elements:
    <xsd:element ...>
    So it would not throw them on nodes using the empty namespace.
    That was really confusing!
  2. When validating .grouproj files using this GroupProj.xsd, I would get this error for all .groupproj files:
    System.Xml.Schema.XmlSchemaValidationException: Type ‘<type>’ is not declared. (in this case for ‘<type>’  ‘ProjectType’).
    That was odd too: the ‘ProjectType’ was indeed declared, and should be valid.

I could hardly find any information about the latter error, but the former gave a few useful hits.

Thanks User weston – Stack Overflow. for answering this: it made me smack to my head (like usual, a case of EBCAK). Read the rest of this entry »

Delphi: First try on an XSD for .groupproj files

Posted by jpluimers on 2013/08/31

Delphi introduced the .groupproj files to support MSBUILD.

I couldn’t find an XSD for it, but need to do some fiddling with those files, so I created one. It’s not very detailed, I think it gets most of the definition right.

The checkin is on my BeSharp.net mercurial repository on BitBucket:

More Delphi PDF manuals (via: Cape Cod Gunny Does Delphi: The One Manual Every Delphi Programmer Should Have!)

Posted by jpluimers on 2013/08/29

Cape Cod Gunny found the PDF of the Delphi 7 Developer’s Guide (1100+ pages of good reading): Cape Cod Gunny Does Delphi: The One Manual Every Delphi Programmer Should Have!.

There are in fact quite a few more PDF manuals of older Borland/CodeGear/Embarcadero products:

These I like most: Read the rest of this entry »

Delphi: about 3 weeks ago, the XE5 branch was added to the RadStudioDemos repository:

Posted by jpluimers on 2013/08/29

Too bad the Sourceforge does not do stats pages any more, so you it is a lot harder to correlate project activity with potential release dates any more.

But: about 3 weeks ago, the XE5 branch was added to the RadStudioDemos repository:

Made it to the Embarcadero MVP Directory

Posted by jpluimers on 2013/08/21

20130822-Embarcadero-MVPIt has been in the queue for a really long time. In fact, all started when chatting with Anders Ohlsson during the inception of the Embarcadero MVP program.

But then the paper work (you know, the thing with written signatures, fax machines, etc) got buried under some projects that lasted both a lot longer than initially anticipated, and were far more consuming also meaning I could not make it to the developer conferences I originally planned.

Recently, I dug out the paper work, then found out that Jim McKeeth – now leading the MVP program at Embarcadero – could lessen the paperwork substantially.

A few manual steps were still involved on both sides, but now I am on the MVP Directory | General.

There is more to it. This fall, I will not only be making it to, but also speaking during at least 3, maybe more Delphi related events in Europe:

Given the time frame, and increase of information about a Delphi for Android product, it might be out or available for beta blogging by then. You can sign up for the beta here, and according to the roadmap it is estimated for release later this year. I hope to be able to play with that soon enough to at least demo a few bits and pieces of it using my Nexus 4 and HTC Sensation on some of those events.

Hope to see some of you there!

reminiscence of the past: DPMI (DOS Protected Mode Interface)

Posted by jpluimers on 2013/08/12

While researching some other historic information about Delphi, I bumped into this thread: New DPMI host – delphi.

If is a small thread describing what kinds and versions of DPMI hosts were available to run Turbo Pascal based programs.

DPMI stands DOS Protected Mode Interface: a way for real mode DOS programs to access protected mode features (mainly memory above the 1 megabyte barrier).

I had plainly forgotten that the DPMI host shipped with Delphi 1, and wasn’t aware you could have a 32-bit DPMI host at all.

Some other memory related abbreviations from that era: Read the rest of this entry »

When your Delphi XE Browsing Path has been destroyed Ken White to the rescue (via: Stack Overflow)

Posted by jpluimers on 2013/08/11

Something overwrote the Browsing Path of my Delphi XE installation.

Symptoms:

  • When debugging a project in “use debug DCUs” mode, the IDE cannot find RTL, VCL and Indy units.
  • When you type `System` in a source file, then press `Ctrl+Enter`, the IDE cannot find the source code to the `System.pas` unit.

It was faster to examine the Delphi XE Library registry settings from Ken White than comparing them with a backup or a fresh Delphi XE install.

Now it works fine…
