Memory Leak in GetChildView is there a resolution?

    Hi,

    We are getting a memory leak with the GetChildView call.  Previous forum post said that you must call the Reset call on the spread to clear any listener to the parent sheet. This does not seem to work... We have applications that are automatically refreshing and after a short period of time the eat up private bytes and crash.

    I have attached a sample project that can quickly show the issue with code.  Please compile and run the application and monitor the private bytes with a utility such as Process Explorer (down load at: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx).  You will quickly see the memory leak each time your press the cycle button. 

    Please advise if this is a defect and the estimated fix date.  If this is not a defect, please advise on how we may fix this issue.

    Thank You

    Hello,


    We should have hit code freeze today, and assuming all goes well in QA, we should be able to release the maintenance release later this week.

    Hello,


    We are close to to releasing the maintenance. The scheduled date was a week ago. We did not think it was ready to go, so we fixed some more things and putting it through the QA testing again. Hopefully this will be ready by the end of next week.

    Thank you for the quick response... Do you have date for the maintenance release?  We have a release scheduled as well and this would be a "show stopper" for us.

    Thank you

    Hello,


    I tested this with the latest maintenance release and was able to reproduce the same issue. I then tested with an internal build that we are testing for the next maintenance release and it was not exhibiting the same behavior. So, it looks like this was a bug that will be fixed in the next maintenance release.

    Hello,

    It would seem that the maintenance release did not fix the memory leak... Please retest with the project attached to the original post.

    Any news on the release?  As metioned before this is a show stopper for our product release...

    Hello,


    I retested again with the latest maintenance release and I see there is still some memory leak, but not nearly as much as there was. I am not sure why I was not able to reproduce this issue with the internal build I tested about a month ago. I sent this to the developer in charge of this area of the Spread for debugging what is causing the leaks. He has found some issues, but is still working on this. I was originally seeing about 8000K of memory being allocated on each cycle. With the maintenance release, this is about 2000K. We have now got this down to 200K, but still looking what is happening si we can make this better. Can you send me your email address so we can continue to work offline on this issue?
