posted June 25, 2002 2:04 PM Hi! Please do next steps: 1)Take your example ...\PowerTCP\Web Enterprise Tool\Samples\WebASP\Bcb5\PostDemo\PostDemo.bpr 2)Compile an run it under Win2000 3)Run TaskManager and check memory allocated by PostDemo 4)Repeatly press POST button in PostDemo 5)After each press check memory allocated by PostDemo You'll see some memoky leak If you change URL to another (for examle wwww.mts.ru), you'll see more effect real examle (post to wwww.mts.ru): post N1 memory 7960 kb post N2 memory 8020 kb post N3 memory 8052 kb post N4 memory 8084 kb post N5 memory 8116 kb post N6 memory 8148 kb it easy to see that each step increase allocated memory to 32Kb. IMHO it depends to HTML page size and it because WebAsp can't correctly clear Response property/ Excuse me for my poor English, i hope you understand me :-))) |

posted June 25, 2002 5:27 PM I checked every sample and the only one that leaks is BCB. That means something is not being freed inside the BCB library. You should probably report this issue to Borland. |

posted June 26, 2002 3:28 AM The point of memory leakage is WebASP1->Response->Body->ReadString(0); May be error is located in Borland's wrapper? created for WebASP? How can i release the memory, allocated by "WebASP1->Response->Body->ReadString(0)"? |

posted June 26, 2002 9:01 AM Actually it's not there as I can comment out that I line and I still see the leak. The leak is occurring because BCB is probably not destroying the IHttpVariableDisp object when we clear release it internally. When you report this to Borland, make sure that you explain that Delphi does it correctly so that they know that another of their products works. |
