Download File with a PowerShell One-Liner

December 11th, 2011 No comments

I was recently trying to automate some scripts on a linux box and I wanted to know if it was as simple to download a file in PowerShell as it is in linux: wget http://example.com/file.jpg

Well as it turned out, it wasn’t, but it wasn’t that difficult either. What we needed was too use the System.Net.WebClient class. There’s one thing to note, in PowerShell you can’t use a ~ (tilde) to reference your home directly, that is to say, you can’t download a file to ~\Desktop you will need to specify the full path, in my case C:\Users\Brangle\Desktop.

How To Use the OpenFileDialog Box in VB.NET

September 7th, 2009 No comments

Using the OpenFileDialog box wasn’t as intuitive as I initially expected, I was thinking I could just drag it out onto my form as a button and place it right where I wanted to. But when I clicked on it from toolbox it just went into the bottom frame of my application, but not on my form like I was hoping for. Below I is an example of a dynamically (aka created at run) created OpenFileDialog.

Make Your Computer Talk with VB.NET Application (and Source Code)

August 29th, 2009 No comments

I was playing around with COM objects in Windows and discovered that I could access the SAPI.SpVoice interface and make Microsoft Windows talk to me. Well needless to say I had to rush and develop and application to do just that. I uploaded a simple applicaton which will just say whatever you type in as an argument. For example SpeakToMeConsole.exe Hello World will make your computer speak the words “Hello World.” The part that really amazes me is that the guts of this program is only 2 lines long, and it can even that can reduced down to 1 line if we create an anonymous instance of SAPI.SpVoice object.
