Direct3d Game programming error
-
Hi I use the following link for starting an application with direct3d: file:///D:/SoftwareProjects/Help/A%20Primer%20of%20DirectX%20Basics%20and%20the%20DirectX3D%20API%20-%20CodeProject.htm I use this book too: Introduction to 3D Game Programming, written by Frank Luna I use Microsoft Visual Studio 2012 C++ and Microsoft DirectX SDK (June 2010). I have the following errors during debug of my application. in the file DirectInput.cpp at the following lines: HR(mKeyboard->Acquire()); HR(mMouse->Acquire()); The error is: one box appears with the following text: Unexpected error encountered. X Error with buttons: YES/ NO I don't know how to attach a screenshot of the error to the message. Could you please help me to resolve the problem. Also in DirectInput.h I changed the declaration of the following: extern DirectInput* gDInput; in static DirectInput* gDInput; Regards

Do you think there might be a connection?

I don't know. If I put extern DirectInput* gDInput I receive the following error during the build process:

I changed in static DirectInput* gDInput because I found the same error here in this link and the explanation was to change extern in static: LNK2019 & LNK2001 - C And C++ | Dream.In.Code[^]

========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========The linker is merely telling you that you forgot to provide a definition of the object that has been declared
extern. You need to provide a line such as the following in one (and only one) of your source files:DirectInput * gDInput = // add initialiser here, or in later code.

Hi I add extern DirectInput* gDInput; in DirectInput.h file. At the beginning of the file DirectInput.cpp I add DirectInput* gDInput = 0; After the build process I received no errors. But during the debug process I still have the same error on the line in DirectInput.cpp: HR(mKeyboard->Acquire()); One message box appears with the following message: Unexpected error encountered: XFile with two buttons Yes/No Regards

Then you need to use your debugger to find out why the error occurred. Randomly changing source code is not a very good way to try and resolve problems.
I try to find the error using debug but till the moment it is not successful. The debuger is going in files as output.c, ullrem.asm, ulldiv.asm, vsprintf.c, The debuger is passing through no source available point and continues till: book_ex1.exe!DXTraceA(const char*strFile, unsigned long dwLine, HRESULT hr, const char*strMsg, int bPopMsgBox)Line 4828

You know where the exception occurs, add a breakpoint soemwhere before that point and run the program. When the breakpoint fires you can single step through the code and check all variables as you proceed, in order to find the offending value.
It is very difficult to find the error line because I look in Disassembly. I use step into and step out. Do you know better way to check errors in disassembly section.

Thank you very much for your help. Everythink is working well when I started the application without debuging.
