Before we shipped IE8 there were no Accelerators, so we had some fun making our own for our favorite web services. I've got a small set of tips for creating Accelerators for other people's web services. I was planning on writing this up as an IE blog post, but Jon wrote a post covering a similar area so rather than write a full and coherent blog post I'll just list a few points:
There's no easy way to use local applications on a PC as the result of an accelerator or a search provider in IE8 but there is a hack-y/obvious way, that I'll describe here. Both accelerators and search providers in IE8 fill in URL templates and navigate to the resulting URL when an accelerator or search provider is executed by the user. These URLs are limited in scheme to http and https but those pages may do anything any other webpage may do. If your local application has an ActiveX control you could use that, or (as I will provide examples for) if the local application has registered for an application protocol you can redirect to that URL. In any case, unfortunately this means that you must put a webpage on the Internet in order to get an accelerator or search provider to use a local application.
For examples of the app protocol case, I've created a callto accelerator that uses whatever application is registered for the callto scheme on your system, and a Windows Search search provider that opens Explorer's search with your search query. The callto accelerator navigates to my redirection page with 'callto:' followed by the selected text in the fragment and the redirection page redirects to that callto URL. In the Windows Search search provider case the same thing happens except the fragment contains 'search-ms:query=' followed by the selected text, which starts Windows Search on your system with the selected text as the query. I've looked into app protocols previously.
Inspired by one of Penn's (of Penn & Teller) articles in which he mentions he has his computer tell him what he wrote in his journal that day the previous year, I've wanted to implement a similar thing with my blog. Now that, as I mentioned previously, I've updated my blog such that its much easier to implement search and such, I've added date range filtering to my site's search. So now I can easily see what on Delicious and my blog I was doing last year.
I've also otherwise updated search on this site. You can now quote terms to match an entire string, stick 'tag:' in front of a term to only match that term against tags as opposed to the title and body of the entry as well, and you can stick '-' in front of a term to indicate that it must not be found in the entry.
I've redone my blog's layout to remind myself how terrible CSS is -- err I mean to play
with the more advanced features of CSS 2.1 which are all now available in IE8. As part of the new layout I've included my Delicious links by default but at a smaller size and I've replaced the
navigation list options with Technical, Personal and Everything as I've heard from folks that that would actually be useful. Besides the layout I've also updated the back-end, switching from my
handmade PHP+XSLT+RSS/Atom monster to a slightly less horrible PHP+DB solution. As a result everything should be much much faster including search which, incidentally, is so much easier to
implement outside of XSLT.
I've looked at my web server logs previously to see if anyone had used my Web Frotz Interpreter and until recently didn't realize that awstats (the web server log report generator) was truncating the query from my URL, so I couldn't tell that anyone was actually using it. But after grepping the logs manually I've pulled out the URLs of visitor's text adventure sessions. If you'll recall, my Web Frotz Interpreter stores the game state in the URL so its easy to see user's game states in the web server logs.
I've put some of the links up on the Web Frotz Interpreter page. Some of the interesting ones:
I've hooked up the printer/scanner to the Media Center PC since I leave that on all the time anyway so we can have a networked printer. I wanted to hook up the scanner in a somewhat similar fashion but I didn't want to install HP's software (other than the drivers of course). So I've written my own script for scanning in PowerShell that does the following:
Here's the actual code from my scan.ps1 file:
param([Switch] $ShowProgress, [switch] $OpenCompletedResult)
$filePathTemplate = "C:\users\public\pictures\scanned\scan {0} {1}.{2}";
$time = get-date -uformat "%Y-%m-%d";
[void]([reflection.assembly]::loadfile( "C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll"))
$deviceManager = new-object -ComObject WIA.DeviceManager
$device = $deviceManager.DeviceInfos.Item(1).Connect();
foreach ($item in $device.Items) {
$fileIdx = 0;
while (test-path ($filePathTemplate -f $time,$fileIdx,"*")) {
[void](++$fileIdx);
}
if ($ShowProgress) { "Scanning..." }
$image = $item.Transfer();
$fileName = ($filePathTemplate -f $time,$fileIdx,$image.FileExtension);
$image.SaveFile($fileName);
clear-variable image
if ($ShowProgress) { "Running OCR..." }
$modiDocument = new-object -comobject modi.document;
$modiDocument.Create($fileName);
$modiDocument.OCR();
if ($modiDocument.Images.Count -gt 0) {
$ocrText = $modiDocument.Images.Item(0).Layout.Text.ToString().Trim();
$modiDocument.Close();
clear-variable modiDocument
if (!($ocrText.Equals(""))) {
$fileAsImage = New-Object -TypeName system.drawing.bitmap -ArgumentList $fileName
if (!($fileName.EndsWith(".jpg") -or $fileName.EndsWith(".jpeg"))) {
if ($ShowProgress) { "Converting to JPEG..." }
$newFileName = ($filePathTemplate -f $time,$fileIdx,"jpg");
$fileAsImage.Save($newFileName, [System.Drawing.Imaging.ImageFormat]::Jpeg);
$fileAsImage.Dispose();
del $fileName;
$fileAsImage = New-Object -TypeName system.drawing.bitmap -ArgumentList $newFileName
$fileName = $newFileName
}
if ($ShowProgress) { "Saving OCR Text..." }
$property = $fileAsImage.PropertyItems[0];
$property.Id = 40092;
$property.Type = 1;
$property.Value = [system.text.encoding]::Unicode.GetBytes($ocrText);
$property.Len = $property.Value.Count;
$fileAsImage.SetPropertyItem($property);
$fileAsImage.Save(($fileName + ".new"));
$fileAsImage.Dispose();
del $fileName;
ren ($fileName + ".new") $fileName
}
}
else {
$modiDocument.Close();
clear-variable modiDocument
}
if ($ShowProgress) { "Done." }
if ($OpenCompletedResult) {
. $fileName;
}
else {
$result = dir $fileName;
$result | add-member -membertype noteproperty -name OCRText -value $ocrText
$result
}
}I ran into a few issues:
