Delphi Component vendors: when you ship source code, make it IDE-browsable as well by compiling with $YD or $Y+

Posted by jpluimers on 2015/05/06

It took me a while to figure this one out:

When you have a registered Delphi, you can Ctrl-Click browse both the units and symbols of RTL, VCL, etc. But Delphi will not recompile these units.

Some third party components you cannot Ctrl-Click browse the units or symbols, unless you put the source directory in the Delphi Library Path (which causes them to be compiled each and every time).

This is because:

  • the precompiled DCUs are in the Delphi Library Path.
  • the source code is added to the Delphi Browsing Path (and sometimes not even that).
  • the DCUs don’t contain information that the source code is Browsable or Referencable as it was compiled with {$Y-}.

These are the possible values for that directive:

  1. {$Y-} or {$DEFINITIONINFO OFF} or {$REFERENCEINFO OFF},
  2. {$Y+} or{$REFERENCEINFO ON},
  3. {$YD} or {DEFINITIONINFO ON}

So please component vendors: when you ship source code, make it IDE-browsable as well by compiling with $YD or $Y+.

Finding the path of xsd.exe from your Visual Studio Build Events

Posted by jpluimers on 2015/05/05

I wrote about the xsd.exe tool before to generate XSD from XML:

But it is much more than that, as it is a great way of generating .NET (not only C# and VB.NET code) from XSD files:

Long ago, xsd.exe used to come as part of Visual Studio, but now it is installed with the various Microsoft Windows SDK versions (of which some are downloadable) which makes it harder to locate on your system.

The really bad thing is that Visual Studio cannot find XSD.exe as part of your project Build Events, as the PATH has not been set up correctly.

Starting xsd.exe from a Visual Studio Build Events

In my hunt for the xsd.exe location, I started with a small batch file to find the xsd.exe locations from the registry:

Lars Fosdal: VS/C#6 is out-delphi-ing Delphi. I hope EMBT is paying attention. Currently…

Interesting, Lars Fosdal writes:

I already liked the 7 minute C#6 video from last year. This is even better.

Find an installed tf.exe, then run it with the command-line parameters specified.

Posted by jpluimers on 2015/04/30

Often I want to execute a TF.exe from the console, but don’t have the Visual Studio environment variables setup. Most of the times I want to run TF.exe from the most current Visual Studio installation, hence this TF.bat file figures out the location of it, then runs with the parameters passed to TF.bat: Read the rest of this entry »

The Clickjacking attack, X-Frame-Options

Posted by jpluimers on 2015/04/29

Front-end web development isn’t my core area of expertise, but every now and then I am slightly more than the usual spectator and do get involved.

This case it was about helping to prevent The Clickjacking attack by using the The X-Frame-Options response header from RFC 7034.

Lots of people seem to have questions about it: Highest Voted ‘x-frame-options’ Questions – Stack Overflow.

So, from The X-Frame-Options response header:

There are three possible values for X-Frame-Options:

DENY
The page cannot be displayed in a frame, regardless of the site attempting to do so.
SAMEORIGIN
The page can only be displayed in a frame on the same origin as the page itself.
ALLOW-FROM uri
The page can only be displayed in a frame on the specified origin.

Some interesting demographics on the G+ Delphi Developers community

Posted by jpluimers on 2015/04/28

Stefan Glienke started some interesting demographics polls on the G+ Delphi community.

Demographics are about group members that actually voted. Which might rule out Delphi programmers not writing English well.

Despite that, I think it actually tells a lot, especially when you read the comments as well.

And it made DavidI provide some background on the geographic distribution: Where in the world are programmers using Delphi? – Blogs.

CRC: The C Stands for Confusion (quotes from the Dr Dobb’s article)

Posted by jpluimers on 2015/04/28

The CRC algorithm isn’t hard, but choosing the right polynomial and parameters can be tricky especially since there are so many permutations to choose from and lots of libraries have made their own (often incompatible) choices.

P2V of an existing XP machine to Hyper-V to have an emergency fallback when retiring old XP physical machines

Posted by jpluimers on 2015/04/27

Edit 20210727:

  • A lot of the links below have died due to link rot (sometimes even the domains have gone), but most of the WayBack machine links marked [Wayback] still work.
  • The same stop [Wayback] stop 0x0000007B can happen when converting a physical machine to VMware (I will schedule a separate post about this):

    Windows XP Virtual Machine failing with stop 0x0000007B

    Windows XP Virtual Machine failing with stop 0x0000007B

Steps:

  1. Put the SATA disk of the XP machine in a different one.
  2. Disk2Vhd on the new machine to create a VHDX of the XP hard disk.
  3. Install Hyper-V on the target Windows 8.1 machine (you need at least Pro for that).
  4. Setup the base VM directory.
  5. Setup a virtual network switch (decide if you want it to be internal, external or private, then bind it to a network adapter if needed).
  6. Add a new VM.
  7. Assign a new directory to it.
  8. Assign memory to it.
  9. Assign the virtual network switch to it.
  10. Save it.
  11. Edit the settings, then bind the DVD drive on the IDE controller 1 to C:\Windows\System32\vmguest.iso.
  12. Connect to the VM.
  13. Start it.
  14. If you get a stop 0x0000007B (usually because of SATA/AHCI/IDE or other MassStorage controller driver issues), then read [Wayback] Jon’s Project Blog » disk2vhd using [WaybackUBCD for Windows to solve the issue as there is no BIOS screen in Hyper-V that allows you to switch from AHCI to SATA and back.
  15. Note: you cannot perform UBCD4Win when you access the Hyper-V host through Microsoft Remote Desktop (the mouse will not work at all, and most keyboard shortcuts will not work either; [WaybackVirtual Machine Connection Key Combinations with Hyper-V – Ben Armstrong – Site Home – MSDN Blogs does not apply).
  16. Boot.
  17. Register Windows (you might need to do extra work to go from OEM to Retail here).
  18. Remove hidden devices that are not used any more and their drivers.
  19. Setup a backup schedule.

Some links that helped me get at these steps:
