Delphi XE2 x64 Extended floating point support: CodeCentral 28488 TExtendedX87: FPU-backed 80-bit Extended type for Win64

Posted by jpluimers on 2011/09/14

in the Delphi 64 world, there is no official support for the Extended data type for various reasons.

If you really need it, then you can use the TExtendedX87 unit by Philipp M. Schlüter as mentioned in this Embarcadero forum thread.

Windows WebSphere MQ client DLLs

Posted by jpluimers on 2011/09/14

There are multiple DLLs you can use as MQ Client.

Most interfaces directly or indirectly use MQM.DLL, which is the interface to the local running WebSphere MQ Manager.

But sometimes your installation doesn’t contain a local WebSphere MQ Manager, and you need to connect remotely as a client.

You need one of these client DLLs, depending if you are using extended architecgture (XA) or not:

  • mqic.dll: Connect as a non-XA client
  • mqicxa.dll: Connect as a XA client

Note that depending on x86 machines, the DLLs can be called mqic32.dll and mqicxa32.dll as well.

Two more FastMM XE2 updates on SourceForge.net in the SVN SCM trunk:

Posted by jpluimers on 2011/09/13

Earlier this week, I wrote about FastMM XE2 update on SourceForge.net in the SVN SCM trunk.

Pierre le Riche has been busy, and got the x64 FullDebugMode working with these two changes to the SourceForge.net: FastMM: SCM:

Needs to be tested, so will do that the upcoming days.

Entity Framework: EF4 – update model from database ignores some changes

Posted by jpluimers on 2011/09/13

Almost a year ago there was a post on the MSDN forums titled EF4 – update model from database ignores some changes.

These are the changes it ignores that I found so far:

  • Column renames
  • Column data type changes
  • Changed foreign key relations

Have you found others?

Which EF versions are worse/better in this respect?

Note that the EF support in Visual Studio 2010 does not warn you if the the model is incompatible with your database.
You will get errors like this at run-time:

Triest bericht: de SDC gaat dit jaar niet door. De altijd kleurrijke conferentie van de SDN voor Nederlandse software ontwikkelaars heeft het dit jaar niet gehaald

Posted by jpluimers on 2011/09/12

Quote van de SDC site:

Helaas heeft de SDN moeten besluiten om SDC voor dit jaar (2011) van de agenda te halen.

In 2012 zullen wij opnieuw een SDC organiseren.

De aankomende SDE van 9 december is reeds in ver gevorderd stadium

Wij hopen u daar te mogen begroeten

Echt heel jammer, want de SDC bracht al heel lang kleur in het landschap van de Nederlandse software ontwikkelaar, juist vanwege de keur aan sprekers (ze haalden altijd de meeste interessante sprekers uit buiten- en binnenland).

SDC (en haar voorloper CttM) was erbij toen Clipper begon, Delphi begon en .NET begon. Warme herinneringen komen boven aan al die prachtige conferenties, en mensen die ik er heb leren kennen.

Laten dus hopen dat het volgend jaar gewoon weer door gaat.

solution for: “Not enough server storage is available to process this command”: restart “Server” service and “Computer Browser”

Posted by jpluimers on 2011/09/12

Recently I got this error when copying a huge number of files from Windows XP x86 to Windows 7 x64

System error 1130 has occurred.

Not enough server storage is available to process this command.

Instead of changing the IRPStackSize as mentioned at
PChucks Network: Server Functionality Affected By IRPStackSize, I just restarted the “Server” service (and the depending “Computer Browser” service) on the Windows 7 system, and everything worked dandy.

FastMM XE2 update on SourceForge.net in the SVN SCM trunk

Posted by jpluimers on 2011/09/11

Pierre le Riche just committed two changes to the SourceForge.net: FastMM: SCM:

Which means that I can demo this during my DelphiLive sessions.

Great work Pierre!

Arrived in San Jose, CA, USA for the DelphiLive tutorial and conference (DelphiLive people get internet free!)

Posted by jpluimers on 2011/09/11

I had a pretty OK direct KLM flight from AMS to SFO.

Apart from some people behind me that seemed to have sufficient motoric coordination issues that they had to grab my chair each time they got up, or put their traytable up.  Some – even Dutch! – seem to think that using force is the only way to get things done. So thank you people in seats 28H, J and K for ruining my sleep.
The advantage of being in seat 27H in a Boeing 747-400 is that you get food really fast, and have direct access to drinks from the galley :)

Frank Stepan – one of the DelphiLive organizers – picked me up at the airport, and got me to the conference hotel in Downtown San Jose.

Check in went smooth.

Connecting to the Internet too: it is a breeze, compared to the Swisscom experience at the NH Hotel in Köln last week.

Not as fast as the KOMED internet on saturday, but you have two choices:

FreeDowntownWifi, which is – err – free. And has reasonable speed.

iBAHN internet, which is – err – free for DelphiLive attendees ans speakers. And also has reasonable speed.

So I upgraded my iPad firmware, downloaded the new TomTom USA Map, and synced my gadgets to the cloud.

Time to do some final preparations on my tutorial and sessions, and then get something to eat.

Companies that ship to the USA, but require USA credit-card or PayPal

Posted by jpluimers on 2011/09/11

Sometimes it is convenient to order something to be delivered in the USA, but from a non-USA credit-card. For instance when visting the USA or when sending a gift to a friend.

Many companies don’t allow that.

These companies are of no use when you live outside the USA, but want to have something delivered within the USA:

  • IBM.com
  • Overstock.com
  • CostCentral.com

Those companies do work though:

This list will be updated over time…
