we have a WPF project witch create some reports (22 exacly) using ReportViewer (2010), all those reports with more than 100 pages and really complex layout. Now we need a Windows Service to create those reports automatic everyday.
I Created the service, using the exaclty same logic, created the installer and build it, but, when I executed, the service only save 14 reports and it throws this exeception:
Win32Exception: Error creating window handle
(My VS is in portuguese, here is the translation for you guys:)
I noticed that the use of RAM of the process goes up in a strage way, hitting the 570MB when the exception is called.
I Thought it could be some problem with the logic of creation of reports, so i created a Console Application Project to call the method and it works just fine.
My doubts are:
1) Is it possible have a limit of RAM use for a service, being necessary I clear the memory after every saved report? (if yes, how can I clear the memory? i inclued the call GC.Collec(); but unsuccessfully)
2) Is it possible that ReportViewer (a Windows.Form Component) enters in conflict with some stuff in Windows Services componenets causing the error?
Best Regards for everyone
