OleAutoObject and C# EventsThis is a discussion on OleAutoObject and C# Events within the Clipper forums in Programming Languages category; Hi I use V.O. 2.8 OleAutoObject to call a method in a C# DLL to submit SOAP transactions. This works well except for large transactions. When the C# method is called, the VO application is unable to refresh it's windows until after the C# method returns. Is it possible for a VO application to receive events from a C# program. This would allow me to call Exec(EXECWHILEEVENT) to update the window. I am able to do this with 32-bit window DLLs, such as XceedZip, but not with dotNET DLLs. Any advice would be appreciated. Ted... | ||||||||

| Re: OleAutoObject and C# Events Ted, I can't answer your question, but another option would be to call the C# method in a worker thread while using the main thread to keep the GUI up-to-date.

| Re: OleAutoObject and C# Events Mike Thanks for the tip the worker thread works well.
