[ITK] Memory leaks with ITK and MFC

[Lee, Kyungmoo]

Dear HTH, Matt, and all,

I created another MFC example using CMake. My source code is in http://user.engineering.uiowa.edu/~kyungmle/share/MFCITK-src.zip. In my MFC example, I added only 2 lines (#include "itkImage.h", #include "itkImageFileReader.h") to MFCITKView.cpp. Adding #include "itkImageFileReader.h" causes memory leaks like the screenshot in http://user.engineering.uiowa.edu/~kyungmle/share/Screenshot-MemoryLeaks.jpg. Do you know why? Please help me. Thank you.

Kit

Hi Kit,

since you didn't use CMake to configure your project, you need to register IO factories<http://itk.org/ITKExamples/src/IO/ImageBase/RegisterIOFactories/Documentation.html> manually.

Add to the beginning of TestMFCITK2015View.cpp:
#include "itkMetaImageIOFactory.h"
and in void CTestMFCITK2015View::OnTestItk():
itk::MetaImageIOFactory::RegisterOneFactory(); //support .mha and .mhd

With these two changes in runs on my machine.

Dear Matt and all,

I made a simple MFC example to use ITK (http://user.engineering.uiowa.edu/~kyungmle/share/TestMFCITK2015.zip). I am using MS Windows 7, MS Visual C++ 2015, ITK-4.9.0, and CMake 3.4.3. When I click [Test]-[ITK] in the menu in Debug, x64 mode, the example clashes in itkImageFileReader.hxx. Can you check my source code? Thanks a lot!

Hi Matt,



Thank you for replying. I would like to use ITK in my MFC application. It has another memory-related problem in my application (See the following figure). I guess that there is a conflict between ITK smart pointer and MFC structure. If you fix InsightApplications-4.8.0/ItkMFC, it would be a good reference for my MFC programming. Thank you so much!!!

Hi Kit,



We are in the process of deprecating InsightApplications.



However, if you create an MFC application that uses ITK, there should be no issues or memory leaks.



HTH,

Matt
