This is one of the things I tend to forget, as you do it once per machine, and the place to do it is not logical to me.
I mainly use it to quickly record a Macro (boy, I wish Office had a TemporaryMacro feature like Visual Studio had. Alas no more: Macro Recording/Playback has been removed in Visual Studio 2012).
The logical place for me would be to have a context-menu on the ribbon where you can enable the Developer tab.
Anyway, this is how to enable the Developer tab in Word 2007/2010/2013: Read the rest of this entry »

At clients, I see quite a few people being confused by this compiler error message:
Error 1 The type 'string' must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method 'System.Nullable'
One of the reasons about the confusion is that a string variable behaves like a value type, but in fact is a reference type because their values can consume a huge amount of memory (thanks User codekaizen).
A few interesting questions on that on StackOverflow:
Anyway, back to the error message above.
Lots of people are confused by it, just see a few questions on StackOverflow: Read the rest of this entry »

One of the few Windows XP machines left is main usage is for the Fujitsu ScanSnap S510 scanner that I have been using for years: it is small, does duplex scanning, emits searchable PDFs through an embedded Adobe Acrobat and Abby ScanSnap Edition OCR license. The Scan button on the scanner “just works” and allows for a “Scan Now, organize later” workflow.
Just Works: if a user is logged in on the Windows machine, which usually is the case.
Next to that, it is used for internet browsing and remote desktop access to VMs in the various clouds: it is more than adequate for that with dual Dell UltraSharp U2407WFP monitors at 1920×1200. The extra 120 pixels over “modern” 1080p do make a difference you know.
I never bothered to upgrade the machine, as it works so nicely and I have had bad experience replacing systems that include embedded licenses: it usually doesn’t work.
Of course I could buy a new ScanSnap iX500, but I don’t want to increase the electronic waste unless I’ve researched if it is possible to get the ScanSnap S510 working on Windows 7 or 8.x, or even on one of my Macs.
So here are some links for further research on a light-weight solution: Read the rest of this entry »

Last year, I had a very odd project at a client.
Their monitoring software was quite odd, and there was no time to create/test/implement a module for it doing SQL query performance measurement any better.
The odd software had two ways of looking at queries:
- in a succeed/fail fashion
- in a count(*) fashion
Don’t ask why it was that way, the monitor was hysterically grown.
So below is a small query script that does what the odd monitoring software can do: provide a select with rows indicating the query response time.
What is does is insert into the #sma temporary table a number of records depending on the query duration.
The partition here is 1 record per 125 milliseconds, aiming for four partitions (green, yellow, orange, red) in half a second.
Note the maximum accuracy is about 3.3 milliseconds.
The script is based on these SQL server features:
I might add a try/catch to fake a finally in case the #sma insert fails. Read the rest of this entry »

Another one from the “missed schedule” series, this one was originally scheduled for 20130927.
These articles were not very clear on the actual steps to take:

This can happen when your Windows Security Token bloat has struck:
… the problem could be minor, or relatively major. You may get weird access denied messages, applications crashing, or strange entries in your event logs. Or worse yet a SID for a group that has a ‘deny permission’ on an object could be dropped into the virtual bit bucket, allowing a user to access a resource they are not supposed to access.
…
Summary of fixes for token bloat:
- Use global or universal groups instead of domain local.
- Increase the MaxTokenSize on all computers
- Convert security groups to distribution groups if they are only used for email lists.
…
There is a hard-coded limit of 1,024 SIDs for the Kerberos PAC (privilege attribute certificate)
…
Kerberos token size still remain to 64k in windows7 / win2008r2.
This is what UWWI did to avoid token bloat: UWWI Token Bloat – IAM – UW Information Technology Wiki.

Ever since around Delphi 2007, it started to use temporary .VRC files to re-build the project .RES file.
It confuses people, and with reason as the only public information about it on the dockwiki seems to be in the Version Info page (though there is more on the other embarcadero sites).
The reason is that parts of the .RES file are no more leading in the process of getting them from your project options to the final binary (EXE/DLL/BPL/…) of your project.
Delphi XE3 for instance can have these resource structures in the .VRC file:
Except for type 24, Delphi XE2 seems to have the same kinds of resource types.
All in all, most if not all of the .RES files are being auto-generated for at least a couple of years now so there is less and less need to put it under version control.
The problem is that if for one reason or the other, your project .RES file becomes readonly, and you get errors like mentioned in Why does a projects res file need to ….
[BRCC32 Error] xxx.vrc(1): error creating xxx.res
.RES in VCS or not?

I usually used netstat with some grep filter for this, but Brandon Titus showed at StackOverflow that the lsof command is much easier to use:
lsof command should be able to do this just fine. Just use this:
lsof -i :<port_number>
lsof -i udp:<port_number>
lsof -i tcp:<port_number>
and all of the processes should come up.
The lsof commands work on SUSE, Max OS X, CygWin and many other environments.
(update 20160304: added more arguments and links)
Two other commands I use often:
netstat -tulpn | sort
(for connected and listening tcp/udp ports it shows processes and port numbers; see the netstat parameters for more details, note that -u includes udp and -l adds listening sockets)
rpcinfo -p ; rpcinfo -s
(shows the ports used by rpcbind)
Note that one day I’ll learn the iproute2 equivalents (many of which have non descriptive 2 letter names like ip, iw, ss, tc, maybe because iproute2), but as OS X still doesn’t have iproute2, I’m hesitating. Anyway, that day:
