i'm using visual studio 2005 in window 7, and create a mfc dialog demo， and i open a fileDialog On a buttion click response function. the code like this :
void CtestFileDialogDlg::OnBnClickedOk()
{
CFileDialog fileDlg(FALSE, L"dav", L"1234567890123456789012345678901234567890");
fileDlg.DoModal();
// TODO: 在此添加控件通知处理程序代码
//OnOK();
}
than i run it in windows 10 system, and click the button, then it can open a save dialog like this
open a save file dialog(i can't upload a image....)
and then i click the save button。 the dialog will close, then i repeat this progress all the day (open then close). private data of this program will increase frome 10MB to 1.3GB。 i think the memory is leak. after that i using windbg to find the biggerst memory in the biggerst heap, like this :
0:004> !heap -stat -h 02d90000 -grp S
heap @ 02d90000
group-by: TOTSIZE max-display: 20
size #blocks total ( %) (percent of total busy bytes)
1b80 d4ef - 16dfac80 (48.29)
500 d4ef - 428ab00 (8.78)
20 14d5a9 - 29ab520 (5.50)
2a0 d4f0 - 22ef600 (4.61)
244 d4ef - 1e26d7c (3.98)
4c 4fdab - 17b4ec4 (3.13)
19c d4ec - 156abd0 (2.83)
138 d4f0 - 1038480 (2.14)
78 1a9df - c7a088 (1.65)
30 35484 - 9fd8c0 (1.32)
40 27f3c - 9fcf00 (1.32)
c0 d4fa - 9fbb80 (1.32)
24 429b5 - 95dd74 (1.24)
14 6a8c7 - 852f8c (1.10)
9c d4f4 - 81c4b0 (1.07)
94 d4eb - 7b17dc (1.02)
88 d4fd - 712668 (0.93)
2a 27ee8 - 68d210 (0.86)
28 27faf - 63f358 (0.82)
18 4296c - 63e220 (0.82)
then i chose one memory block which size is 1b80, and want show the stack of alloc this memory:
:004> !heap -p -a 095063c8

_HEAP @ 2d90000

and it show this is alloc by windows_storage.dll， so i guess memory leak is in windows_storage.dll, does any one have same problem， adn known how to fixed this issue ?
