Enjoyable Conference and Training

[MartinQ]

Many thanks Christian for your efforts in organising this gathering.
Both days were very interesteing and useful.
It was very helpful to meet a variety of other developers, who so
freely shared their knowledge.

I look forward to future meetings and hope there will be ongoing
interchange online.

I would invite any of the attendees who have not already done so to
join my LinkedIn group.

I would like to also thank Christian, and wish him a `happy birthday` for today.

Also many thanks to all others who presented - a very interesting day.

I have now put some examples on the web of RS projects to create a simple container control,
populate a form with a few instances of a control via code and to create a slider
control based on the ones I use in the scanning project.

Examples were developed and tested under Windows and are in a zip file at:-

http://www.cmas-net.org.uk/rslug/examples-120404.zip

The zip contains 3 example projects and a sub-folder containing the images used.

The powerpoint slides with screenshots etc are at:-

If anyone wants a description of any other element of the scan app I will try to help, if possible.


Small technical note:...

The subject of `flashing` on the screen when presenting some UI elements came up
at the meeting and I've had a bit of a think on that - and experimented a little :
I found that if I use a label control for text on the slider that I get some flashing of the
text if the slider is moved quickly.  The fix was to remove the label and draw the text string
directly in the `paint` event for the canvas.

For elements like the current scanner state animation, I do use code to ensure I do not
force a refresh / repaint if the state has not changed.

For many control.Refresh calls I add the parameter `false` to stop the background being erased
as the control, is redrawn.

Best regards

Hi rsul'ers,

If you are wanting to view another example of a Real Studio WE database with links to looking up Google Maps for locations then please check the below site out. It is a draft and when finished will go live. I am interested in opinions from a RS perspective.

Contact me if you want to know how parts of it were created.

Yours Sincerely,

David Cox

hi david,

got back from Orlando on last monday. We have a great time there... got sun tanned and learn a lot of new stuff at the Real World 2012. 

the WE online app look amazing... good work... i assume you used web container for the search result.

[Cox David]

Trisha,

Yes, but I found a bug with deleting containers from a page — you are supposed to close them, but they still exist. So I create a new window with containers then close/reopen it when needed.

Resizing the cloud graphic on the main page was a pain, but fixed after I modernised the Picture — just scaling it caused a crash.

[Trisha Duke]

i haven't try creating and deleting web container yet. My WE app is simply a web page with a few web container and just showing and hiding the web container. 

The WE app is simply a add-in for my Artscene/ACMS system which enquire the database backend which might be a single user db or multi user db.

So how did you modernise the Picture???

- Trisha Duke

[Cox David]

Trisha,

I need to delete containers since I have one container field that I embed multiple containers onto, one for each resultant search result. The forums say that closing a container will delete it, but even I close and hide it, it is still there.

The SQL behind the scenes gets a bit crazy when it tries to get distances from you based on your latitude and longitude then give you the results in increasing distance. Plus there are many lookups within lookups, zooming into Google maps, drawing pins and getting your location.

Below is the generic function (not my own) to modernise my pictures, then I use the below routine to resize it:

myBanner.Picture = commonWE.ModernizePicture(headersky).ScaleMBS(self.Width, headersky.Height)

Function ModernizePicture(input As Picture) As Picture

  If input.hasAlphaChannel Then Return input

  

  Dim result As New Picture( input.Width, input.Height )

  result.Graphics.DrawPicture( input, 0, 0 )

  Return result

  

Exception err

  if not commonWE.HandleException(err, "Method: " + CurrentMethodName) then Raise err

  

End Function

[Trisha Duke]

sound cool on the modernise picture.
