[C++] Help using Templates

[Amrok]

Hi, i'd like to use a Template as a placeholder for a argument type. Like:
function(int arg1, T arg2)

my header file looks as following:

class MyClass
{
	public:
		template <typename T>
		bool MyFunction(int arg1, T arg2);
}

this is my class.cpp code;

template <typename T>
bool MyClass::MyFunction(int arg1, T arg2)
{
	if (arg1 > arg2)
		return true;
	else
		return false;
}

i call this function as following:

MyClass MyClass; //create object
MyClass.MyFunction<float>(int arg1, float arg2);

but it simply wont work..

Can somebody help me please?
How can i implement this if i have more than one source file...?

This is the error output...

1>main.obj : error LNK2001: unresolved external symbol ""public: bool __thiscall MyClass::MyFunction<float>(unsigned int,float)" (??$MyFunction@M@MyClass@@QAE_NIIIIIM@Z)".

EDIT: It won't even work if i define all members as 'inline'...

EDIT2: Yes i know it works if i put the whole code into the header file.. but lulz .. thats not clean

You can't put an implementation of a template in a .cpp file if it's going to be called from other translation units, because the compiler needs to be able to see the implementation at the time the template is instantiated, it can't be deferred to link time*. You need to put the implementation in your header file, then you won't get errors about unresolved externals.

* Nitpick corner: Yes, there is the 'export' keyword, but nobody actually implements it except Comeau, and it's deprecated in C++0x anyway for that reason.
