Chinh Do

I am finding more and more things I can do with PowerShell everyday. The other day, I had to “touch” a file… one line is what it takes:

(ls testFile.txt).LastWriteTime = New-object DateTime 1991,12,31

• Use Powershell array expression syntax @(…) allows you to force a scalar return value to be wrapped in a array, if it’s not already in an array.

Windows Mobile / Pocket PC

• I needed a way to stream music and other media to my Windows Mobile phone (Samsung SCH-i760) and all the PCs around the house. Orb seems to be the answer. I’ve only had it running for a few days but it seems to be working great. I can stream music and photos (have not tested videos yet) to any PC in the house or anywhere on the net. I can also listen to my entire music library on my i760 phone anytime, anywhere through Verizon Wireless’s unlimited (with a catch… not to exceed 5GB) EDVO connection.

  

• I am a Google Mobile guy, but Yahoo! Go for Windows Mobile also looks very cool. I downloaded it to my Samsung SCH-i760 a few days ago. I am still checking it out but here are a few things I like:
  • Nice and responsive interface.
  • Built-in RSS Reader.
  • Street and satellite maps.

    Here are a few screenshots:

Tips and Tricks

• I can’t believe I didn’t know about this Visual Studio command before: File.OpenContainingFolder. Asmita A Wankhede mentioned it, but he left a few important details out. By default, this command does not have a shortcut, so you would have to assign one to it (try CTRL+SHIFT+ALT+O). Also, the "item" that this command works on is the currently opened item in the editor, not the selected item in the Solution Explorer. See my Visual Studio tips article for instructions on how to create new shortcuts (section 3 - Make New Shortcuts).

• I recently tried and liked GhostDoc very much. It’s a free Visual Studio add-in to help write XML documentation comments. Roland Weigelt wrote a nice intro article on GhostDoc on DotnetSlackers here.
• SyncBackSE is a great folder synchronization utility. It has tons of features… maybe even a little bit on the bloated side. It costs $30 for a single license. If you just want something simple, Microsoft’s free SyncToy may do the trick for you.

   

Gadgets

• From CES, it looks like Blu-ray will be the winner of the HD format war. No, the war is not completely over, but this was the landing at Normandy… so to speak. The loss is just too great for the HD-DVD camp to recover.

Software and Tools

• SgmlReader is an XmlReader API over any SGML document including HTML and OFX for example. HTML is an SGML grammar, so you can use this tool to convert HTML into well-formed XML. I started to use this for my current project last week and it’s been working great so far.
