ya now i got it. They are having virtual keyword.(pure virtual function>
i was confused with that throw() in betweeen

virtual void Fun() throw();   
virtual void Fun() throw()=0;
virtual void Fun() throw(bad_alloc)=0;

If you wanted these icons in message box, then you can mention it while displaying message box only.
e.g.

AfxMessageBox(_T("Error message"),MB_ICONERROR);//for error 
AfxMessageBox(_T("Error message"),MB_ICONEXCLAMATION);//for exclamaition

In other places see following methods.

Use IDI_ERROR.

Use IDI_EXCLAMATION.

Use LoadIcon[^] and SetIcon to load these predefined icons.

As explained earlier, AfxMessageBox should suffice you if you are not doing any customization with it.
Otherwise, Override OnInitDialog to look it something similar to,

BOOL CMyDlg::OnInitDialog()
{
  // other initialization code
   ...
   SetIcon(LoadIcon(NULL,MAKEINTRESOURCE(IDI_ERROR)),FALSE);//set the icon
   return TRUE;  // return TRUE  unless you set the focus to a control
}

Hai,
Iam using this line for getting the commandline argument.
The error iam getting is:

wchar_t** szArglist = ::CommandLineToArgvW( ::GetCommandLineW(), &numArgs );

error C2039: 'CommandLineToArgvW' : is not a member of '`global namespace''
error C2065: 'CommandLineToArgvW' : undeclared identifier
error C2440: 'initializing' : cannot convert from 'int' to 'unsigned short ** '
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast.

Can anyone suggest how to rectify this error..

Item's problem of states and action

Q1:
if(action&ODA_FOCUS)
{
CBrush brush(RGB(255,0,0));
pDC->FrameRect(&rectItem,&brush);
}
I wonder why I do this in DrawItem,when I ran the program and clicked the item which is not the first one,the first item's edge turned red too?

Q2:
What is difference between ODA_FOCUS and ODA_SELECT?

Q3:
As I click an item in a listbox,and then I click another control,does combination of (state & ODS_SELECTED)&& !(action&ODA_FOCUS) correspond to the item I clicked firstly?

Using LoadLibrary on EXE to call exported functions?

rforte26-Mar-07 17:08

rforte

26-Mar-07 17:08

I have an executable with an exported function like this:
__declspec(dllexport) const wchar_t * UniqueID( void );
...
const wchar_t *
UniqueID( void )
{
return( L"XYZ00001" );
}

I then do the following in another executable:
typedef const wchar_t * (*pfnID)(void);
pfnID GetUniqueID;
HMODULE hMod = LoadLibrary( L"foo.exe" );
GetUniqueID = (pfnID)GetProcAddress( hMod, "UniqueID" );
const wchar_t * id = GetUniqueID(); // Returns a valid address but data is zero

This above code fails by returning a pointer from GetUniqueID() but the data is all zero'd out.

When I rebuild foo.exe to be a dll (foo.dll) the above code works fine.

Is it possible to use LoadLibrary() to open an executable and get an exported function? The docs say it's possible but I'm wondering if the loader isn't doing proper fixup when LoadLibrary() is called on an EXE.

I notice when I step into the code the value stuffed into @eax looks like the static address of "XYZ00001" and not the fixed-up virtual address I would expect. For example, LoadLibrary returned 0x010f0000 and my function address is at 0x011b614a but the address returned from GetUniqueID() is 0x006595a0.

When I rebuild foo.exe as foo.dll I see LoadLibrary returns 0x10000000, GetProcAddress returns 0x10001000, and GetUniqueID() returns 0x101178ac. In this instance the data is correct.

Any ideas?

Admin Elevation through Manifest

What do I need to specify in the program's manifest so that Vista will know that this program requires Admin privileges?

I want Vista to automatically launch a UAC prompt when the program is run.

That's a very useful document, thank you. But where can I find an example of the actual syntax required?

The manifest appears to be an XML document, so where exactly does the "requestedExecutionLevel" item go?

very tough socket programming problem,

xyhan26-Mar-07 13:52

26-Mar-07 13:52

Hi,all,

I used java for a server and C(winsock) for a client. now the server
can be activated by the client's connect(...) function and then can send data to the client. the client can correctly receive the data from server and then correctly send data back(it can correctly return the bytes sent) but the server can not be activated by the data(it blocked there when it try to read data from the socket even if the client send a lot).

I spend all most one day but can not get the solution, any helps will be appreciated!

From your statements it seems to me the problem is on the java server side...

unless...

Even if send() returns the number of bytes "sent", that doesn't mean the bytes got received by
the other end, or even made it that far.

Is the protocol TCP?
