A MyArray may be used only for double or String types. In practical terms this has little impact because most compilers never supported it. Feedback will be sent to Microsoft: By pressing the submit button, your feedback will be used to improve Microsoft products and services.

Yes No. To have all the information available, current compilers tend to require that a template must be fully defined whenever it is used. That includes all of its member functions and all template functions called from those. Consequently, template writers tend to place template definition in header files. That is not actually required by the standard, but until improved implementations are widely available, we recommend that you do so for your own templates: place the definition of any template that is to be used in more than one translation unit in a header file.
Unless we have a compiler that has implemented the new export keyword, placing the template member functions in a separate implementation file won't work.
Because the templates are not functions, they can't be compiled separately. Templates should be used in conjunction with requests for particular instantiations of templates. Sorted it. Thanks guys.

Why remove from project in Method 3? Member I have tried method 3 with a template that is used in my current code project.
It compiles and links fine, although I did not remove its implementation from the sln file VS You suggested that it has to be done though. Could you explain why it has to be removed and maybe also think of reasons why it works in my case? Whenever you want to make changes to Something. In Something. Build the solution you may get linker errors. Exclude Something. Build the Solution. Regards, Mike -- modified May am. Method 1 is the best as it will optimize the build.
Instead of creating temporary function a cleaner way is to use template class definition as below. Google says don't separate into forward declarations. Chal McCollough. Their justification is not clear from the Self-contained Headers section but becomes clear when you read the Forward Declarations section.
Thank you Google! I have sth. Using Method 2 it passes, but I don't like include test. Method 2 has to change main. Cheers, Ray. Got a solution, similar idea: in test. Method 1 isn't compile at visual studio you also can create new file "head. Method 4 similar to method 2 ddCubinator 8-Jul Writing a normal header file, including it normally into the source file and instead of including header and source file into the program, just include the source file.
When the source file is included, it automatically includes the header file. Beginner's question Member 1-Jun I've read the Reason section and i understand that the compiler needs the definition of the class methods so it can create object of some type.
I cannot understand why the compiler has no such problem when it is dealing with ordinary class not template. Doesn't it need the definition of the methods and if so how it finds them?
I'm sorry if the question is stupid? My vote of 5 Member Aug I love that this post explained each step and why it didn't work. I understand the material now. Thank you! I cannot reccommend this article as it's not using the correct terminology. The declaration of a function is just the prototype you normally see in the header file.
