Conclusive way of testing if content has changed since last FTIndex

The standard way of testing, db.LastModified > db.LastFTIndexed, works great in a production environment. When you're doing performance tuning of an application that updates it's FT-index, it's not so great.

NotesDatabase.LastModified also includes changes to design elements. If you use the above test to fire a NotesDatabase.UpdateFTIndex, then the check, db.LastModified > db.LastFTIndexed, will return true until a document is modified in the db/the FTIndex is updated. Changes to design elements is ignored by the FT-indexing service on the server.

NotesDatabase.UpdateFTIndex is relatively expensive (I would think the more documents in the database -> The more time to check if the FTIndex should be updated). In an application of mine, I use NotesView.FTSearch to find certain content in views (to create HTML menu, etc). I use a class that updates the FT-index before it does the search. On regular pages, there is created two instances of this class. In an application with 200 documents, it takes the server ~130ms to do two calls to NotesDatabase.UpdateFTIndex, when the application is indexed. When I do performance tuning, I do changes to design elements, not content. Therefore the aforementioned test to determine if content has changed is flawed.

This is my so far best alternative to the "standard check". It takes 16ms to do twice in the aforementioned application. A savings of ~115ms.

Function contentChangedSinceLastFTIndex( db As NotesDatabase ) As Boolean
 Dim session As New NotesSession
 
 Dim lastFTIndexed As Variant
 lastFTIndexed = db.LastFTIndexed
 
 'First test (least resource-hungry)
 If Not ( db.LastModified > lastFTIndexed ) Then 
  contentChangedSinceLastFTIndex = False
  Exit Function
 End If
 
 'Conclusive test - test if actual documents (not design elements) 
 'have been changed since last FTIndex
 Dim dateFTIndexed As New NotesDateTime ( lastFTIndexed )
 
 Dim col As NotesDocumentCollection
 Set col = db.GetModifiedDocuments( dateFTIndexed )
 If col.Count > 0 Then contentChangedSinceLastFTIndex = True 
End Function

Help get the NotesUI-bugs in Notes 8.5 fixed

If you're having problems working with the NotesUI classes in Notes 8.5, or are planning to upgrade to Notes 8.5.x in the future/have applications that use the NotesUI-classes. Please contact Lotus Support and open a PMR to request inclusion of the fix in an 8.5 FP.

Thanks, Andre for making people aware of this issue.

Rearrange your Windows taskbar with Taskbar Shuffle

Update: 64-bit version of Taskbar Shuffle. The one on snapfiles/download.com doesn't seem to work with 64-bit Vista. I also found a similar program, Taskix. I haven't tried it, but from what I read on a forum, it works more or less like Taskbar Shuffle.

I recently dropped back from Windows 7 on one of my laptops to Windows XP, due to crackling sounds when playing music off my USB DAC.

One of the Windows 7 features I missed the most was the ability to rearrange the open applications in my taskbar. Thankfully, someone has made an application that lets you do this in earlier versions of Windows, Taskbar Shuffle (I downloaded it from SnapFiles).

At work, I start some applications in a certain order (hour sheet@Notepad++, Lotus Notes, Domino Designer). If Notes crashes and I have open a lot of applications, I often close all other apps, to get the order back. No more of that.

Speaking of useful applications. One of my all time favorite utility applications is Launchy. It lets you launch applications at the blink of an eye. Highly recommended if you prefer your keyboard to your mouse.

Clipboard Recorder is a must when working with code (you can also configure it to keep a history of bitmaps).

For screen capture, I use Gadwin PrintScreen.

At home, avast keeps me safe from viruses, and SUPERAntiSpyware (horrible title) is used to look for spyware.

LotusScript: Case insensitive replace

Recently, I've been working on "cloning" CMS-type applications. To avoid a lot of unnecessary work, I run an agent on the copied CMS that rewrites the UNID of the documents to that of the document in the original CMS, and rewrites local links to point to the cloned application.

Since the urls can be typed in multiple ways, the way to go for the link rewriting is case insensitive replace. This is provided in LotusScript (no need for Java).

Replace( htmlBody, webDbNameSource, webDbNameClone, , , 1 )

The last parameter tells replace that it should do a case insensitive replace.

All the parameters (taken from the documentation)
0 (default): case sensitive, pitch sensitive
1: case insensitive, pitch sensitive
4: case sensitive, pitch insensitive
5: case insensitive, pitch insensitive

Example of pitch difference: e, é, è

The CMS applications in question are web applications, so the body is text/HTML. If you're working on cross platform (Notes/Web) applications, I'd think there would be more work to clone an app (RT-navigation *shudders*).
