I googled this error and tried every possible solution.
1. created x86 directory without brackets
2. installed visual studio in C:\VisualStudio Path (Not in Program files)
3. Installed 64bit Oracle10g
4. Tried Oracle 11g
Still this problem exists. Kindly help

i found out some more details. in early 2013 there was Window 7 update KB2670838. which was causing same issue back than in our software am facing in window 8 right now. uninstalling that update fixed it in window 7. I checked in window 8 there is no such update available/installed.

I have checked and make sure dispose is being called. As I mentioned its working fine in window 7, When I close forms, memory is getting clear. Problems come in window8. Am using same code on window 8 but memory is not getting clear and handles keep on increasing until exception occurs.

let me post exception here.

These handlers are not getting dispose in window 8, as I mentioned in windows 7 and XP these handlers never exceeds 500

doesn't work, still directing to my system DB.

thanks alot for your response. Am also searching some topic. but I liked your idea too, Am going to do some search in it and see if i could write paper in it,
thanks again and waiting for more ideas.
marking as answer.

Thanks for your response. this is actually really good one. let me search if some work or paper is written on this.

Any other ideas?
what about this research paper.
"Concurrent Object-Oriented Development with Behavioral Design Patterns"

I was thinking is it possible to implement this in some other design pattern.

I am out of luck :(

thats the point, my main is actually method 1, which is actually hundreds of forms load events, that is calling method 2,
method 2 is common in all those, whats happening here is method 2 returns dataset, and in method 1 they are doing some thing like this if ds.table(0).rows.count > 0 {} what was happening before that when method 3 throws exception than no effect happen here as this ll not get executed in method 1, now method 2 returns nothing and all these method 1 produces new exceptions as there are no checks like this if ds isnot nothing andalso ds.Tables.count > 0 etc etc. :(

method 2 is common in all those,
whats happening here is method 2 returns dataset, and in method 1 they are doing some thing like this
if ds.table(0).rows.count > 0 {}

what was happening before that when method 3 throws exception than no effect happen here as this ll not get executed in method 1, now method 2 returns nothing and all these method 1 produces new exceptions as there are no checks like this
if ds isnot nothing andalso ds.Tables.count > 0 etc etc. :(

reason why i cant change in method 1 because its been called from 4000 places and i cant change in all those forms

I cant Change Method1 as I mentioned before, I have to do something in catch of Method2 so that All code execution stops from after where Method 2 is called.

This is what I tried But it ll kill purpose, because am showing custom error in Method2, after showing error if I throw ex again, then default system exception ll also get shown, i dont want to show default Exception by throwing ex again :(

Am Parsing XML and Applying different Set of rules, and send back response in XML.

Yes its parsing XML.

Thanks, this is what I was looking for.

i already installed CR run-time for Visual studio 10, still not working.
