• Petchey VS8 resource can't open include

  I am using VS version 8.0.50727.42 (RTM.050727-4200). I converted a VS 2003 project, and I am trying to compile. The project depends on WTL7.1, which I downloaded and set the project compilation paths to point to the appropriate WTL include directory. During compilation I get to a "pddm.rc" file that references a WTL file, like this: #include <atlres.h> When the compiler hits that line, it says: Error 1 fatal error RC1015: cannot open include file 'atlres.h'. However, my project paths are set correctly - and other header files from the same location as atlres.h are found just fine. This problem seems to be unique to an include being processed from within a resource file . Indeed, I've found someone else o ...Show All

• fusg C++/CLI finalizer chaining in a class hierarchy

  Is the finalizer ( ! ) in a C++/CLI derived ref class automatically chained to call the finalizer of its base class or do I have to manually implement this in my derived ref class The documentation in the "Destructors and Finalizers in Visual C++" topic is confusing about this. Also if the finalizer is protected rather than public will it still be called originally by the GC ref class Base { public: !Base() { /* Release unmanaged resources */ } }; ref class Derived : public Base { public: !Derived() { /* Release unmanaged resources */ // Does !Base(); have to be manually called } }; Peter Ritchie wrote: From Destructors and Finalizers in C++ : Unlike Visual C+ ...Show All

• project2n5e0o1 Using AFX_MANAGE_STATE

  I've a MFC extension DLL. My question is that when all i need to call AFX_MANAGE_STATE( AfxGetStaticModuleState()); I suppose, it needed to be called while Creating (initializing) the resources. e.g Functions which creates Dialog, Icon, Bitmap (or whatsoever in the DLL resource file) The KB Article  says that we only need to call this inside the callbacks and windows procedures instead of putting in all exported functions Currently I put the manage state code in the functions which deals with resources. Am I correct or not Do I need to limit the usage of managing state to the resource creation(initialization) process Could you please put some light on this Brian, Thanks for the reply. I think the error will be spawned ev ...Show All

• Jim_Fort_Worth floating point error trouble

  Hi, I have this really annoying problem with float data type where I get a precision error when I try to do this : float num = 0.0f; for(int i=0; i<100; ++i) { cout << num <<"\n"; num += 0.01f; } In my computer everything works fine until the 83th iteration where num should changes from 0.83 to 0.84 but instead I get 0.8399999999. Any idea how I should handle this In my real program, num is a variable from a library so changing its type to double is not an option As explained in this FAQ , IEEE 754 cannot represent accuratly decimals such as 0.1, because they are not an exact sum of inversed powers of 2. Please read the FAQ. Thank you ...Show All

• tmiller3 Cannot see the version information in the properties of an EXE.

  I am building a C++ project that creates an executable. When I right click and see the properties of that executable, there is no version tab that will give me the version information of that exe. Can you please tell me what I can do so that I can see the version information of my exe. I would like to put the company information, copyright and file versions in that exe. I know you would do that in C# with AssemblyInfo.cs but I am sure about C++. Please help me out. thanks Thanks it worked. You need to insert a VERSIONINFO resource into the RC file that is part of your EXE. with the resource editor you can easily do this (right click on the RC file in the resource editor and choose "add resource" then choose "vers ...Show All

• Brandon Tucker This code snippet makes no sense...

  I've come across some code syntax I've never seen. It compiled, but I don't know how, or what it even does! I've been reading a book about DirectX, and in one of the examples, this little piece of code was present: D3DXMATRIX *D3DXMatrixIdentity(D3DXMATRIX *pout); "D3DXMATRIX" is a type, of course. And "D3DXMatrixIdentity" is a function, of course. Now I don't see how this works. Okay, to break it down, first we have a type, which is D3DXMATRIX, then we have the indirection-operator (which I assume is a pointer), and then we have a function (perhaps a call) with a new D3DXMATRIX (pointer) as it's only parameter. How the heck does this work It isn't just a regular function-call. It isn't a function-call that' ...Show All

• Gavin Lilley C1083 Permission denied

  Hi, I'm getting this C1083 Permission denied error when I try to build an application (console type) project A which includes files from another project B (static library type). The B project includes files from a math library C (GSL). When I build the static library B, I have no problems. The problem is when I try to build A, and it complains about having permission denied to access a folder which turns to be the folder containing the .h files of C (included by B). I hope this is clear enough, if not please tell me. I'm using XP Home Edition and files have no permissions at all. Here is the text: 1>c1xx : fatal error C1083: Cannot open source file: 'C:\Documents and Settings\Alix\My Documents\genetic context\GSL\include' ...Show All
