GDI Leaks Detection

[Jurnero]

Hello! Several times I had a problem with GDI-objects leak.
My colleagues helped me solve the problem. But I would like to ask for help! How are you searching this type of leak? What utilities or plugins for VS can help me?

Programming language: C++. Visual Studio

Are you using C or C++ ?

You use managed pointers aka smart pointers.

It's harder n C since you need to set up your own reference counters.

Then you create these objects using a function that increments the reference count.

You delete using a function that decrements the reference count and deletes the object if the count is zero.

In C++ it is handled using managed pointer objects which contain a reference to the object being managed.

In today's world you should never be using naked pointers anywhere.

Thanks for the answer.
Added details to the question
Programming language is C++/Visual Studio

In this case study up on std::shared_ptr <> and its associates.

Be sure your GDI object ctor/dtor work correctly.

Depending upon whose GDI object you are using,like one written in C, you may need to embed the object in class object so there is ctor/dtor available.

Thank you for this clarification. I think it should be very helpful to me.

Maybe you need to spend more time studying the theory. Try reading several articles about the memory model in C ++. This will help you understand how memory is allocated.
Also, you can use GDI leak detection tools.

Perhaps you `re right. What books, articles do you recommend to reading? What tools do you mean?

I can advise such debugger as Deleaker. It works with GDI leaks.
Task Manager can show the presence of such leaks.

OldStory, thanks for the answer. I've heard good reviews about this debugger.
