Advantages A DLL can be used by the widest programming audience possible. Maybe you should add this as a full fledged answer? –Aardvark Feb 11 '09 at 19:15 add a comment| 3 Answers 3 active oldest votes up vote 88 down vote accepted All that a developer is required to do is to use the __declspec(dllexport/dllimport) specifier before the class name if the whole class needs to be exported, or before the method declarations Select Build»Build to compile and link your DLL. his comment is here

Fixed the Esc key problem in the 'Select Dlls' dialog-box. However, you first must address the issue of C++ name decoration. Is that in the SDK? –Aardvark Feb 11 '09 at 20:04 2 Don't forget to add the module definition file into the project's linker settings - just "adding an existing Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you!

Translate all string entries to the desired language. I'd like the use __declspec(dllexport) and not have to use a DEF file. break; } return TRUE; } Once the DllMain function is complete, write the routines that you intend to access from the DLL. //Function

Please explain. I suspect that the SDK checks to see if there aren't any overloads for a particular function, and if not, it applies C linkage to it. All versions of the Dynamic link library have been listed below from most recent to oldest. - 32 Bit (x86) (2004-01-31) Download this version  - 32 Bit (x86) Note: This document applies to MSVC 2010.

MSVC compiles your source as C++ if it has a .cpp or .cxx extension.

Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! The purpose of this article is to show several methods of exporting C++ classes from a DLL module.

If you want to use it on Windows NT, you should add psapi.dll into your system32 folder. RegDllView - View registered dll/ocx/exe files on your system GDIView - View the GDI handles/resources allocated for your process, and allows you to trace and detect GDI leaks on your software. If you are using Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP, you can use the same method to run the Command Prompt as administrator. This method provides a clean, well-defined object oriented interface between the DLL and its client.

Detailed description is given of the advantages and disadvantages for each method. Period. extern "C" causes C style name decoration. Advantages An exported C++ class can be used in the same way as any other C++ class.

A hypothetical C++ compiler that fails to support COM efficiently is doomed to oblivion in the Windows market. Inside the DLL module, the XyzImpl class inherits from the IXyz interface, and implements its methods. To do this, use TLS to provide unique data for each thread.

Such a DLL can be used with any modern C++ compiler on the Windows platform.

std::shared_ptr class // will call this method automatically in its destructor. NOTE! Thanks!! --luke Sign In·ViewThread·Permalink Re: versioning and adding functions [email protected] 2:54 [email protected] 2:54 TL; DR: 1. break; case DLL_THREAD_ATTACH: // Do thread-specific initialization.

Subscribed! You can use this option to easily set multiple breakpoints in WinDbg debugger. I wasn't worried about calling-speed either. pXyz->Release(); } } } return 0; } However, if the variable is global, not a class attribute, no problem.

The parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or the name of the column, like "Function Name" and C++ Mature Approach: Using an Abstract Interface A C++ abstract interface (i.e., a C++ class that contains only pure virtual methods and no data members) tries to get the best of extern "C" XYZAPI IXyz* APIENTRY GetXyz(); In the above code snippet, the factory function GetXyz is declared as extern "C". Yes, it's a bad idea. 2.

A member-less C++ class that consisting of pure virtual methods only is nothing more than a virtual table, i.e., an array of function pointers.
