Re: "The class UiaAtkBridge.Table could not be loaded"

Hi,

I first installed Mono on Ubuntu 10.4 using Synaptics - I selected what libs
I thought might be useful, et voila, it was working fine for my needs. Then,
after I upgraded to Ubuntu 10.10 the applications I wrote previously didn't
want to start, and the error appeared similar to the one in the original
post. At first I thought it was some configuration error, so I did uninstall
_everything_ even remotely related to mono and installed it back, again
using Synaptics.

Still didn't work, so I decided to go from scratch: I downloaded mono,
monodevelop, gtk-sharp and other latest sources, and started building. I
finally got to UiaAtkBridge and then I saw some compilation errors -
something to do with delay-signing the library (for this I had to add
parameters to the compiler flags) and some classes (e.g.
TextContainerWithGrid) implementing Table interface just weren't up to date.
To be precise: public int[] SelectedColumns and public int[] SelectedRows
properties were missing, which were apparently added to the latest
UiaAtkBridge.Table. After getting around these errors I was able to
successfully build the library and putting it in my bin folder, solved my
problem.

To be true I don't think I need any accessibility libraries (at least I'm
not using them explicitly), but my simple programs - referencing System and
System.Drawing - seem to load them anyway.

That's the whole story. Now you see that I didn't do anything 'special' at
first, and I wouldn't have if the normal setup worked fine.

Best regards,
Michal
