Hi,

I create template class, declared in .h file and implemented in .cpp file. But it do not compile the functions in the .cpp file.
But when I put them in the .h file, it's OK.
The .cpp file is in the source files list.
I use VC 6.

Thank you.

Is it possible to send the errors or the files ?
I think that you got linker error when you had tried to compile.

Yes. Linker error for only those functions used.

Link error:
TemplateClass.obj : error LNK2001: unresolved external symbol "protected: struct DataList<int>::NODE_t * __thiscall DataList<int>::DetachNode(unsigned int)" (?DetachNode@?$DataList@H@@IAEPAUNODE_t@1@I@Z)
Debug/TemplateClass.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

But this function is in the .cpp file.
It is...

template < typename T >
DataList < T > ::NODE_t* DataList < T > ::DetachNode( UINT uIndex_i )
{
// some codes
}

If I put this function in .h file, it works fine.

Delete all your debug or release directory.
Make sure you have exacly the the same function definition in cpp and h file.
And don't include cpp file in header file

Recompile file.

How to organize template source code.[^]

My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.

word does not work well with nested compound document

template is to class as class is to object.

a class isn't an object, it is used to create objects.
a template isn't a class, it is used to create classes.

as a template isn't a class it isn't code.
when you declare an instance of a template the compiler generates the appropriate code for the class - that's what will get compiled.

I am working on writing a MFC application supporting both container and server of compound document. Because i use a third part y ole client in my application, and meanwhile I also want insert my object into word.

However, I find Microsoft word does not work well with a nested compound document(for example insert a wordpad object into word, and then insert microsoft paint into wordpad). There are error message of "unable to update client".

However, Microsoft Excel/Power Point work well with a nested compound document .

Does anyone can help me in this regard?

Rich edit control char set problem

I'm using the CRichEditCtrl to display text. I also want to be able to change the font and - within the font - the character set.

For font selection, I use the CFontDialog. I can select the font and also the character set (skript).

Applying the selection to the rich edit control changes the font as expected, but the char set does not change.

E.g., if I have eastern europe text to display, I have to change the char set from 'Western' to 'Central European'. Regardless which char set I assign to the rich edit control (by using SetDefaultCharFormat(cf)) nothing changes.

If I try to do the same in Wordpad (the classic rich edit application), it does not work as well. Changing the char set skript does not change anything in the text.

Is this a common problem of the rich edit control ?
Is there any idea to solve the problem (by still using the rich edit control) ?

Thanks for any hints in advance.

question for guru's familiar with IPv6... how do i port if_nametoindex interface in Windows. is it supported? i'm currently porting a C application in linux that uses if_nametoindex and i'm having a problem converting this part to windows....

case AF_INET6:
t_addr6 = (struct sockaddr_in6 *)&s_loc;

if (cmdinterface)
t_addr6->sin6_scope_id = if_nametoindex(cmdinterface);
t_addr6->sin6_family = AF_INET6;
t_addr6->sin6_port = htons(local_port);
strcpy( t_addr6->sin6_addr.s6_addr , inet_addr( local_host ));
l_len = sizeof (struct sockaddr_in6);

thanx....
