Hi,
I have a long process to do to populate my UltraGrids. So I want to display a simple gif animated Ajax-like loader image.
I tried first with System.Windows.Forms.PictureBox without success; the image animation is stopped when the Progress process is started. When the process ended the animation continue but I dont need anymore the animation ...
So, I saw that Progress Openedge 10.2 GUI .NET is single threaded...
So I tried after that by loading a webpage in my Frame using a System.Windows.Forms.WebBrowser. But without success again I get the same issue... Is anyone has an idea how to display my animation during the loading process? Best regards, Eric.
Yes you're right, the AVM is single threaded. You may receive an update of the image, if you are able to run the PROCESS EVENTS. statement once in a while.
The subject was discussed in this thread here: http://communities.progress.com/pcom/message/28049#28049
I never tested it, but your observation sounds like it should not be working when the AVM is busy.
Haha!
Thank you very much!
It was trivial in fact, take a look on my solution in pseudo code.
FOR EACH ... query...process
THIS-OBJECT:myP
ictureBox:Refresh().
...process
END.
By that way I give back to my PictureBox the hand to refresh itself during my process.
Have a nice day,
Eric
Hi Eric,
Does it make any difference if you user PROCESS EVENTS instead of pictureBox:Refresh()?
I would expect not.
