I dont see content of this article XListCtrl - A custom-draw list control with subitem formatting[^] of Mr Hans Dietrich but I think it can solves your problem.

Does anybody know why inline keyword isn't always understanded from the compiler/linker?
I like to use inline as often as possible (to all the member functions!!), but sometimes it gives me a linker error (function not found) so I cut it:

in file.h

inline double foo(...);

and in file.cpp

inline double foo(...){
..
}

then it works!!! OMG | :OMG:

Does this happens only to me?

(I'm using VS 2003 .NET, and 2002)

To get inlining to work you generally need to implement the function in the header file. i.e. no separate declaration and definition, all in one like:-

in file.h

<br />
inline double foo(/*...*/)<br />
{<br />
//...<br />
}<br />

Note that there are numerous reasons why the MS C++ Compiler might refuse to inline or auto inline functions without being asked not all of which are even publicly documented. There is no way to gaurantee inlining even using __force_inline the compiler can still ignore the instruction. Also inlining tends to disappear in Debug builds as compared with Release so it's difficult to prove whether it's happening or not wihtout examining Release code at the assembly level. Any kind of instrumentation or leaving debug information in is quite likely to alter the compiler's inlining decisions anyway. Microsoft's take is basically truct the compiler and don't worry about it.

Nothing is exactly what it seems but everything with seems can be unpicked.

I have a lot of small functions that are there only to let the code be more readable...but I need at the same time high performances.
Many of them are some simple wrappers to other functions, inline looks necessary. Cry | :((

Thanks for your time;)

if you really want them to be inlined, you can always use simple #define macros.

I use inline only in the header part of a function. Often I see code where inline-functions are completely in the header implemented. Unsure | :~

"inline" is also an optimization option. If optimization is important it is better to proof the quality of code, for instance function calls in loops (!!!), temporary objects ...

AFAIK, inline is only a compiler hint. The compiler can decide to everride the inline.

I created dialog bar in CHtmlView SDI application by clicking rebar application.
But whatever buttons I placed on that bar remain disabled. Even if I tried using
only style WM_VISIBLE in precreate window. Or m_dialogbar.EnableWindow(true);
or GetDlgItem->(IDC_BUTTON1)->EnableWindow(true); . The buttons remain disabled.
How to use it. I just want editbox URL to be navigated on button click,and simple back ,front buttons.

   I think that you need to add ON_UPDATE_COMMAND_UI and/or ON_COMMAND message map entries for the command IDs for the controls on the dialog bar, same as you would normally do for a toolbar or for menu items.

   See if adding an ON_COMMMAND entry for IDC_BUTTON1 helps.

   Peace!

Drop Thunderbird E-Mail into MFC Application

Hi everybody,

is it possible to drag an E-Mail of Thunderbird or MS Outlook into a MFC Application
and to drop it there?
I think yes, but which informations are delivered?
Is there propably an existing tool which accepts E-Mails and show the informations about it?

Big big thanks Smile | :)

Outlook allows dragging and dropping mails to different applications like a user can drag the item from the Outlook window to MS WORD, in essence you can drop an item on to a MFC application from Outlook or Thunderbird, read it using MAPI and then display the details of the item or do whatever you want.

Somethings seem HARD to do, until we know how to do them.

Did you made an application which uses this technique?
Does a "MAPI Object" been stored into the clipboard or transfered via Message
and my MFC application need to read it and then i have all the informations ?

Seems simply but very hard without never working with it D'Oh! | :doh:

   I do not know about Thunderbird, but Outlook's drag-n-drop data format is not an easy one to work through. There are quite a few steps you have to do to actually get to the message portion of the email.

   I was trying this a few months ago for an application I was working on, and it was a serious PITA - the data formats and structures used are not documented very well and in fact, I never got it working in a completely stable way (random memory problems), so I left it out of the product.

   I wish you good luck!

   Peace!

MUHAHAHAHAHA,

if a C++ expert like you don't get it workin, so it's at the moment impossible for me.
I'll consider to change the expiration.

The user should save the mail in .eml and the tool extracts the file Big Grin | :-D

Thanks anyway you two !

   Being a C++ expert does not automatically mean that you can figure out how things work in Windows, but thanks for the complement anyway!

   Not impossible - you may have more time on your hands do figure it out than I did...

   Peace!
