Hi,
I have a class template that I want to derrive another class template from - could anyone help with the syntax?
My base class is declared as:
template <class type, long size> class xyz
{
};
What would I need to derrive a templace class abc from the above?
TIA

please come back to your post, click on the little [Modify] link at the bottom right, and there, check the "Ignore HTML tags in this message (good for code snippets)" check Box to let use see the whole template declaration.
note that i ask you to modify your post, not to repost it !
now i imagine you have this :
template<class T>
class xyz {
};
then you can do this (i think) :
template<class T>
class child : public xyz<T> {
};
thanks in advance...

My base class (which is OK) is declared as:
template <class type, long size> class xyz
{
};
My derrived class is declared as:
template <class type, long size> class abc : public xyz<class type, long size>
{
};
The compiler throws out a lot of errors, the first being:
Error C2146 syntax error : missing ',' before identifier 'size'
The next error is
Error C2977 : 'xyz' too many template arguments - see declaration of 'xyz'
TIA

change it into :
template <class type, long size>
class abc : public xyz<type, size> {
};

Hi,
i've included various projects(60) in my workspace and
i've used objectspace-STL within these, since now. I don't know if i have installed
software that damaged this old good state or i done something else, but from now i have to set the linker switch "ignore all standard lib.", that it would work - compile and link.
I get following fault, if I don't set it:
: error LNK2001: Nichtaufgeloestes externes Symbol "__declspec(dllimport) public: __thiscall std::_Winit::~_Winit(void)" (__imp_??1_Winit@std@@QAE@XZ)
So I looked for _Winit and find out that my DLL needs msvcp60.dll to work. I know this dll, it's for
MS C++ Runtime Library. But the question is:
How can i use objectspace-stl again and how can i ban this dll ?
Is there a switch within VS, with that i can get my old good state ?
Anyone who has experience how could i solve the problem ?
Thanks in advance
Eddy

Why not try the Mozilla groups for this information? If you have a specific ATL question, that's different, but your asking a generalized question that pertains to Thunderbird ... this is NOT a Mozilla nor Thunderbird discussion group.

hi ,project settings "mimize CRT use in ATL" make it no, this is under configuration properties in general tab.

Hi folks,
I need my application to act in a different way when the workstation is locked, but I can't find any windows API to check this. I´ve found the following comment under the "LockWorkstation" function at MSDN:
"There is no function you can call to determine whether the workstation is locked. To verify whether it is worth attempting to update your user interface, you can test whether or not your window is visible. This also has the advantage of identifying when the user cannot see your user interface because it is obscured by another window, minimized, or offscreen."
Unfortunately, it doesn't work  : I tried this calling the IsWindowVisible() method of CWindow (WTL) but it always return TRUE (window visible) even when workstation is locked  .
I'll appreciate comments and suggestions.
Thanks in advace.

Instead of checking to see if the workstation is locked, why not check for keyboard inactivity and change the how your application "works" by that means?
Just a thought ...

And more a question. In add-in for Outlook it is possible to fill in field To in the new mail?
|
|
|
|

" this site " I know. He has not helped me, though I have understood.

Yes it is definetly possible to modify the subject line in the new mail. But somewhere you would have to place a string value to be displayed in the subject line using :
put_Subject(_com_util::ConvertStringToBSTR(stringtobedisplayed));
Does this solve your problem
p.s : You need to convert a string to bstr before doing this. So I have used _com_util::ConvertStringToBSTR()

First of all you have to take the object for mail item pointing to the new mail and then you can use:
put_Subject(_com_util::ConvertStringToBSTR("your subject line");
