If you do not even know where to start with your project then I suggest you go and talk to your teacher about it.

You need to use the debugger to gather more information, especially about the content of the variables that may cause the error. Also please mark the lines where the error occurs.

If you really want help with this issue then please do what I suggested in my first response.

I mean you need to run your program under the debugger to trap exactly where the error occurs, what the error is, and what variables, pointers etc. are possibly causing the fault. Without that information it is impossible to guess what may be going wrong.

That is as a good as sending a picture of your care and saying "it won't start".

Don't you have and compiler ? Why don't you just compile and debug the code ?

Why don't you? Seriously, this site is here to help when you have problems, but it is up to you to gather the correct information. We cannot do everyone's work for them.

I shared the code and error message what else you need ? If you cant help just tell type here it's not big deal

I have told you more than once what we need. Create a proper debug version of your code, then run it in the debugger in order to gather proper information.

The error is probably here:

uniform_int_distribution < int > passNumberDist(1000000, 99999);

The first distribution parameter should be less than the second.

Bug with unique_ptr and /clr code in Visual Studio 2015

Thank you I solved the compiler error !

FYI - I have found and reported a bug with std::unique_ptr when used in code built with /clr in VS 2015.

Consider this code:

C++

void accept_ownership( std::unique_ptr<MyClass> ptr ) { ... }

void test() {
   std::unique_ptr<MyClass> mc = std::make_unique<MyClass>( args );

   accept_ownership( std::move(mc) );
}

When accept_ownership is called in C++/CLI code, mc will be destructed and accept_ownership receives a unique_ptr pointing to freed memory. There will be a double-free at exit as well.

I've reported the bug with send-a-frown and it is NOT fixed in the Update 1 RC. Let's hope it's fixed in Update 1 RTM.

The code works as expected when not built with /clr.

Rendering problems with DirectWrite

As a warmup for a more complex project in C#, I have started to code a C++/CLI library to allow simple access of C# applications to features of DirectWrite. (I am aware that there are such helper libraries already out there but I was not able yet to get them to work with in Visual Studio 2015 and with Windows 10.)

So far so good. A first test run showed the text in the target window but not as I would have expected for ClearType display. A screenshot of the displayed text can be found here.

My understanding of the relating MSDN documentation is that ClearType is enabled by default. The title bar text of the window is obviously set up with text in ClearType. I guess I missed a setting in the DWrite factory but I do not know which.

Does anybody have an advice for me?

It looks like your coordinates are being calculated incorrectly and you are not leaving enough space between lines of text.

Thank you for your response. You had indeed a good idea but I am afraid that this is not likely the reason:

You can see from the screenshot, the character 'g' is shown completely where other characters like the adjacent are not shown completely.
The text has been sent to DX as one single block, without the explicit specification of leading. I would assume then that DX selects a sufficient leading.

Meanwhile, I have made several more tests with my application but I have not found a way yet to improve the text display. However, I do not give up. ClearType works well on my computer; any application - except mine - is using it successfully.

I have collected my little test in a ZIP file which can be loaded from this location. I am currently using Windows 10 and Visual Studio Community 2015.

Well I am no expert in DirectX, but that is certainly what it looks like. I would suggest you take a look at https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/DWriteLineSpacingModes[^] to see how Microsoft does it.
