A property lost in tIME

March 25, 2014

The built-in PNG property handler does not support the tIME chunk for some reason. Why? I don’t know and it is only 7 bytes of data that is easy to parse!

We can fix this with a little shell extension. Sadly PSCreateMultiplexPropertyStore is documented to be read-only and I did not check if the system supplied version of IPropertyStore supports aggregation. We could hook the interface methods or do other tricks but just creating a simple wrapper seems to be enough to get a read-only version to work.

This means passing NULL as the verb if you are calling ShellExecute[Ex]. When you do this the shell will do its magic to find the default verb:

I see your errorlevel and raise you a process exit code

December 7, 2012

Have you ever written a batch file that is more of a “application” than a script? Of course you made sure ERRORLEVEL is set correctly so when your batch file is a part of a larger script, IF ERRORLEVEL error checking can be used. What could go wrong?

For some crazy reason, cmd.exe does not use the expected logic when you use the && and/or || syntax. I assume part of the problem is because the batch file is executed by cmd.exe itself and there is no child process and no real process exit code.

Fixing this requires some hacky workarounds and is generally a big pain in the ass.

Never means never, unless you are the taskbar

I like to keep my taskbar buttons grouped a certain way but explorer forces per application combined groups even when you tell it never to combine!

The DWM hates the paparazzi

August 24, 2011

The windows team is probably working on the third generation of the DWM but the screen shot capability is still in the dark ages, just take a look at the B8 blog:

A third-party tool should not be required to create a simple screen shot of a window in 2011.
