Hi,

Do you know why the Report Control is so slow when it is destroyed or when all items are removed ?
 
You did a special method for batch Rows allocation that greatly accelerates the add of items, but deallocation remains very slow.
 
You may see this problem in your sample "ReportCustomHeap".
 
It's a little strange, because it doesn't seem to be linked with memory allocation (only a small amount of memory is used). Perhaps there's some code in your destructors.
 
Thank you in advance for your answer,
Regards,
Sergio

Are you just seeing this behavior in debug builds? If so, such behavior is normal and you should not see similar delays in your release build.

No, it does the same in Release builds.
 
You may reproduce this behavior with your sample "ReportCustomHeap".
 
Try to add several records, then remove all the records or close the document.

Hi,
 
I have just downloaded and checked this issue with the MFC Codejock Release 12.0.0.
 
It's still slow with this version in Release mode.

I ran the ReportCustomHeap sample application, added 200,000 records via repeated use of the "Batch Add 20,000 Records" menu item. If I then "Remove All" records or close the document, everything clears up fairly quickly (takes roughly one second or so).

Hi,
 
Yes, you're right, sorry and thank you.
 
Now I know why I had this problem : it is due to the Release build ran in debug mode.
 
Could you please also give me an answer for this post :
 
Thank you in advance,
Regards,
Sergio
