WatiN SelectList Name

2008-06-03T11:37:00Z

WatiN does not currently expose the name property of a select list. However, there is still a way to get at it if you have the element that represents it with a reference to Microsoft.mshtml:

foreach (Element element in ie.Elements)

{

string name = (((mshtml.HTMLSelectElementClass) (element.HTMLElement))).IHTMLSelectElement_name;

}

WatiN TextField and ASP.NET AJAX MaskedEdit Controls

2008-05-16T21:19:00Z

If you have tried to user WatiN tests to set the value of text boxes/fields, you likely have run into a few things.

First, this...
ie.TextField("ID").Value = "some text";
is much faster than this...
ie.TextField("ID").TypeText("some text");

Next, if you are using client side validation or any of the MaxkedEdit controls, you probably discovered that it does not play too well. I originally used this just to make it work for me...

TextField textField = ie.TextField(Find.ById(new Regex(controlId)));

textField.Focus();
for (int i = 0; i < value.Length; i++)
{
textField.KeyPress(char.Parse(value.Substring(i, 1)));
textField.WaitForComplete();
}

For one, it is pretty slow. Also, it just does not seem to work 100% of the time. WatiN exposes one additional method to make this a lot faster. Eval() will allow you to inject and run javascript in the instance of the browser..

TextField textField = ie.TextField(Find.ById(new Regex(controlId)));
string eval = string.Format("document.getElementById('{0}').value = '{1}'", textField.Id, value);
ie.Eval(eval);

Happy Testing!

Graphics.FromImage(bitmap), but not from all PixelFormats

2007-01-01T22:46:00Z

I am playing in the System.Drawing.Imaging namespace, and had an issue trying to draw over the top of bitmaps I had pulled from the web via HttpWebResponse.GetResponseStream.

This Code:

Graphics graph = Graphics.FromImage(bitmap);

Returned this error:

A Graphics object cannot be created from an image that has an indexed pixel format.

The image I was trying to consume had a Image.PixelFormat of Format8bppIndexed. After searching a number of places, I finally found this bug listing. Turns out it’s an old issue that has not been fixed in 2.0. Either way, the fix is pretty simple. The following line of code will change the PixelFormat to Format32bppArgb, and the Graphics.FromImage method takes that format:

bitmap.MakeTransparent(Color.FromArgb(0,0,0));

For me, this was definitely a needle in the preverbal haystack. I think my problem is that I often search on the wrong terms. Google will tell you when you misspell something. I just wish it told me when I search on the wrong keywords for my problem. So I will put those keywords here, so a keyword search might lead you here. Hope it saves you the two hours I lost.

Image.PixelFormat
ImageFormatConverter
System.Drawing.Imaging.Imageformat
System.Windows.Media.Imaging ( yeah, my solution might have been there also, but wasn’t ready to use 3.0 for a Click Once deployment. )

And the error again for good measure...

A Graphics object cannot be created from an image that has an indexed pixel format.

Line Rider Beta 2! Trademarked and Headed for the Wii

2006-12-19T01:14:00Z

Shhh... Listen. The slurping sound you hear is coming from the collective decline in the planetary GDP. This thing is addictive. I will admit to at least a good five hours of playing with this back in beta 1. I think my four year old is nearing the century mark. Beta 2 is a huge improvement. New features:

The pencil tool now seems more smooth
Each line shows by color what is the front and back of the line
A Line tool that now lets you make perfectly straight lines
An Eraser! One line at a time.
Swatches: Blue for regular, Red for acceleration, and green for decoration only. (They all turn black when playing)
Zoom!
The Flag. This one is huge. You can save the riders current position during simulation, a flag is placed at that location, and the next 'play' will start the rider at that spot!

The console rights have apparently been aquired by inXile, and they are talking Wii and Nintendo DS launches.

Defrag Nightmare!

2006-10-09T23:07:00Z

Take a guess what percentage free space would you guess is available on this drive? This is the server of a client of mine.

Ok, here's math: It is a 57gb partition with 21gb free. That's right. You can have a defrag graph like that and have 37% free space available on the drive! Unbelievable. I have tried more options than I care to relate, but here are the major ones:

Removed the page file completely. This box has 4gb memory, so I think it can manage.
Moved the top 25 most fragmented files identified by defrag completely off of the system.
Uncompressed the drive. Yea, I know, never ever use compression. It wasn't me.
Defrag with windows scheduler about 45 times.
Defrag for five days with Diskeeper, both continuous, and the 'comprehensive'. It claimed to have removed over 100k fragments, but I sure don't see any evidence.

There is nothing in the recycle bin, and sql and other major services are stopped. At this point it seems to me the only course is to completely format and rebuild the os (win2k btw..). Any ideas? Please...

Pentagon Awards Contract for Hybrid Powered EM Hardened Humvee

2006-08-03T18:10:00Z

WASHINGTON (Bedrock Daily) – The Pentagon today approved a design to produce a hybrid powered EM hardened Humvee to meet special requirements laid out for the current US armed forces operating in the world theatre. The Pengagon is responding in part to increased pressure to make the modern military more 'eco' friendly. The need for a EM hardened ground vehicle comes in the wake of current tensions in the middle east and the need to increase readiness for urban EMP threats....(read more)

Search Engine Optimization: A Mini-Case Study

2006-07-26T13:22:00Z

I was having a chat with a buddy of mine, and he mentioned a bike his friend was about to purchase. An ‘R1’ he said. I am not fluent with motorcycles, so I quickly googled “r1 bike”. I was very surprised, laughed, and showed him what Google listed as #1 out of 1.9 million results for ‘r1 bike’. A site in the UK called Crafts-Unlimited has a page selling a kit to cross stitch a Yamaha YZF R1. Yes I said ‘cross stitch’. This is a page where you can buy a kit to sew your next family heirloom of...(read more)

Sharing CS Posts: Digg, Del.icio.us, Reddit, etc…

2006-07-22T12:25:00Z

ScottW released a sharing module along with his ScottWater.CS.Modules. I had noticed these in the 2.1 beta 1 release, and also the more customized version on one2one.dell.com. I had not yet made the time to do any modules for CS, so this looked like a nice way to get my feet wet. I grabbed the source from ScottW’s module, and made some slight changes. Now, you can do all the following with just changes to your communityserver.config: Update or remove the ‘share it’ message preceding...(read more)

Searching for CS

2006-07-22T11:09:00Z

I went searching for cs skins. Community Server skins that is. Googling "cs skin" returns 11 million results. Files: Themes and Skins (communityserver.org) is up there at #6. That is pretty impressive considering the competition for the 'cs'. If you Google "cs", you get a sense of the competition for that is out there for the abbreviation "cs": Counter-Strike (#1 now, but for how long?) computer society computer science Photoshop CS CS Lewis CodeSmith. With all that, these...(read more)
