CreateFile() and GetFileSize() if you use Win32 API or _stat if you're using CRT API.

I´m searching the Internet für Icons and Bitmaps which I can use in the Toolbar (VC++ MFC). Do you now a good link?

This:
template <typename T>
struct deref {
typedef void type;
};
template <typename T>
struct deref<T*> {
typedef T type;
}; doesn't work in VS.NET. Got any ideas to work around the compiler? 
What I want is something like this: typeid(deref<int*>::type) == typeid(int)

I don't think it's possible. boost/type_traits has such facilities, but the case you're looking for requires partial template specialization (hey, if the Boost guys weren't able to make it in VS.NET chances are it is damn hard). If you can get by with info about whether a given type is a pointer or not, this can be done in VS.NET (if you're interested I can send you some code detached from Boost for easier comsumption).

True!

For my particular problem that won't help me much anyway.
My problem is basically this:
template <typename T>
struct deleter {
void operator()(T* pObj) const { delete pObj; }
};
typedef std::vector<AClass*> AClassVector;
AClassVector vec;
vec.push_back(...);
...
std::for_each(vec.begin(), vec.end(), deleter<AClassVector::value_type>());This doesn't work well since my deleter template works on a different level of abstraction. operator()(T* pObj) becomes operator()(AClass** pObj) which delete won't handle. So, I basically wanted to do this:
std::for_each(vec.begin(), vec.end(), deleter<deref<AClassVector::value_type> >()); I know I can pass AClass as template parameter to deleter<> (which I did later  ). But I think deref<AClassVector::value_type> would have been a more elegant solution.

Can anyone explain me what I have to do with this error?
0xC0000005:Acces Violation
The debugger stops at:
//perform specific initializations
if (!pThread->InitInstance())
{
if(pThread->m_pMainWnd !=NULL)
{ TRACE0("Warning: Destroying non-NULL m_pMainWnd\n");
pThread->m_pMainWnd->DestroyWindow();
}
nReturnCode=pThread->ExitInstance();
goto InitFailure;
}
nReturnCode = pThread ->Run();
The debugger stops at the line; pThread->m_pMainWnd->DestroyWindow();
Thanx,
kind regards,
Geert

put a breakpoint before the line and see what it is returning..and what u were expecting..so you will know why it is happening.. I guess you are doing it wrong way..so it doesn't know anything such as window to be destroyed..try m_pmainWnd->destroywindow(); i hope this will work..;)
cheers..

Just a quick stab in the dark, but the fact that your
UI Thread failed to initialised :
pThread->InitInstance() // returns false
.. would indicate that the handle to the thread's main window,
pThread->m_pMainWnd, may not have been initialised.
This would explain the memory violation when attempting to do
pThread->m_pMainWnd->DestroyWindow();.
The fact that m_pMainWnd is not NULL is not an indication that it is a valid handle.
..
...
<shockhorror>
and my golly god, did I see a goto statement at the end of your code?

Mail having attachment type "octet-stream"? and encoding base64. how to decode this?
thanks in advance
Murali

An octet is a byte. An "octet-stream" mime type is just an unspecified binary file, which could be a .EXE, an MP3, a ZIP, or anything you may want.
A base64 encoded text can be decoded by a base64 decoder.
Sorry, I know the last explanation sucks, but base64 is a very simple encoding and there are lots of encoders/decoders freely available on the web, and, IIRC, even on CP.
The .NET framework also has a base64 decoder included, so if you are doing MC++ this would be easy too.

Hi,
can I create a button which not get focus if it is clicked? (a focusless button like a button in a toolbar)
The focus should stay with the current control and not be "stolen" by button click. Possibly it can be done by overriding WM_LBUTTONDOWN ...? It would be great if I can avoid ownerdraw (to keep XP style button, if code is running on XP). What I found on Google mentions it has to be a onwerdraw button rebuild from scratch.
At the moment I simply set the focus back after button is clicked, but that's not that great.
Thx for help, Moak

For example:
CButton* bt = (CButton*)GetDlgItem(IDC_BUTTON1);
void XDlg::OnButton1()
{
bt->EnableWindow(FALSE);//For Focusless
}
void XDlg::OnRbuttonDown()
{
bt->EnableWindow(TRUE);//For back to Focus;
}
Is this helpful to you.

yaiii... amazing that this really works. nice trick, chepuri_uk!
I changed the code a bit and use something like this now:
void CButtonFL::OnLButtonDown(UINT nFlags, CPoint point)
{
EnableWindow(FALSE);
CButton::OnLButtonDown(nFlags, point);
EnableWindow(TRUE);
}
Gratefully, Moak

i can't undesrtand...what is it you want..in a toolbar too we have focus on the buttons..when we click them..you can just disable it..and use if you want like that..
cheers

yeah like a button on a PC... like when you click and all the focus was gone... huuu.... like a button but just like without this focus... like when you click and... it then does not take focus... like in a toolbar we have. It's kind of button.
