Hello,
Is there a reason why the default exception dialog has a cancel
button to kill the application ?
We often use an exception to signal wrong entry of data or so,
because it stops all further processing.
If the user then uses the cancel button, the program is simply
ended, which is not

I have been wondering that for 5 years (since I moved from Delphi),
but was to shy to ask. ;-)

Oh, good point to discuss about the use of exceptions.
I use exceptions only for really unexpected things.
That a user will sometimes input wrong data must be expected by a programmer so
I do not treat this as an exception.
With unexpected things I mean all the things that are outside my code.

Yes, examples are useful if there are no docs and you should look at them. I
got a tiphtmlpanel to work in my project by ripping some example source
code. What you can also do is type in the component name followed by a
period, then variables and functions will pop up. That's also a useful way

And sometimes ctrl-clicking (left) on the function/procedure gives you
insight into the interface... and then ctrl-up-arrow you can even check the
code implementation...

It is not possible to place a TProgressbar in a listview. (item.data
does nothing, it's for user defined data independent of the LCL)
What you have have to do is to

An unhandled exception IMO is due to some software bug, which the user
cannot cure in any way.

G'day all,
When I'm compiling an app I can include all my fpc details with {$I %Rhubarb%}.
Is there an easy way I can include the current lazarus svn revision in my
compiled applications?
I looked at parsing $lazdir/ide/revision.inc, but I wonder if there is a better
way I'm missing?
