Hi,
I am getting access violation error when i try with "LoadRequest". Please refer the attached screenshot for code and call stack.
Please let me know your thoughts on this.
Used CEFWindowParent, TChromium and Timer.
Thanks & Regards,
John

The TChromium.LoadRequest procedure has these code comments :
https://github.com/salvadordf/CEF4Delph ... .pas#L2431
Code: Select all
// WARNING: This function will fail with "bad IPC message" reason
// INVALID_INITIATOR_ORIGIN (213) unless you first navigate to the request
// origin using some other mechanism (LoadURL, link click, etc).
If you just need to send a POST request then use the
URLRequest demo.

CEF applications need to handle interface references carefully to avoid crashes. You have to be extremely careful if you use pointers instead of interface references because it's easy to break the reference count. Personally, I wouldn't use a message to send browser pointers to avoid those problems.
Set the interface variables to NIL instead of using "
FreeAndNil".
