I can't access on variable 'Self' because....

[David28]

Hello,
In my Programm I get an EAcces-Violation Exception.
It occurs when I use the 'Scanline' method of a TBitmap - Object which I named FBitmap.
If I verify FBitmap with the debugger I get the message:

"Auf Variable 'Self' kann wegen Optimierung nicht zugegriffen werden"

"I can't access on variable 'Self' because of optimizing."
(Sorry,I dont know the the exact English translation.)


A instance of FBitmap exists. FBitmap is not nil.

Has anybody an idea what this means ?
Any idea about possible causes ?
Under which circumstances could this happen ?


Thank you very much for your answers.

Hi there.

Send a codesnippet and we will solve it for you... Probably...

There is always another way to solve it, but I prefer my way.

The variable is most likly a local within a procedure or a function, the debugger can't see these if you stop on a breakpoint (due to optomistaion).
I belive newer versions of Delphi allow you to add a watch on locals, but I don't know how well this works as yet.


Steve: Delphi a feersum engin indeed.

I have found the error.
It was an aftereffect of an overflow-error.
Thank you very much for trying to help me.
