You have to set the report view style, LVS_REPORT.

i have a class as mentioned below.The size of the class is only 16.Can anybody give me an explanation for this.Is this because of padding
class EXP
{
char c1;
char c2;
int i1;
int i2;
char *ptr;
static int mem;
};
THANKS IN ADVANCE

There are "paddings" between some members of a structure. This is for convenience for the CPU to access. But you can change the padding size.
To view the positions and the sizes of paddings, you can list the addresses of each members as below.
EXP obj;
printf("obj.c1: 0x%p \nobj.c2: 0x%p \nobj.i1: 0x%p \n", &obj.c1, &obj.c2, &obj.i1);

Hi,
I am trying to open a file, whose name is in UNICODE string with a Byte-order Mark (BOM). How do I open such files? The CFile class fails to recognize such a name.
Thank you.

#include <fstream>
wchar_t file_name[] = L"hello.txt";
std::wfstream f(file_name, std::ios::in | std::ios::out);

Thank you for your reply. But an existing file with Byte-order Mark (Ex: FFFE), will not open with the above code.

I just made a file with the mark EF BB BF in the beginning three bytes of the content, and the content is in Chinese. I use the below code, and it can open and load data into fstream variable. (Sorry for my typo in last reply. Note the "w" of the type name.)
std::wifstream file(file_name, std::ios::in | std::ios::binary);

When you create SDI/MDI with FormView using wizard, it will tell FormView can use printing support (Maybe that's the problem).
If I am not wrong, there is tutorial how to use print (form view) in code project.
Good Luck

I created the SDI with the simple View as base class.
I added the forms to it.
But I want to call the OnFilePrintpreview from one of the forms.
One more thing : I want to preview the content of only simple view
not form..

I can use classwizard->message Maps->message add OnInitDialog,
but in vc8:dialog property->message, no WM_INITDIALOG, why?

I believe MSFT changed it to Virtual Function since VC6. Check in the Overrides tab.
If it is changed in VC6, I dont know why it's still showing as message map, Anyway it will not make any entries in you message map even if add the message handler

Gents,
now a more serious question.
There is a small application i would like to trick, it opens up the log file with CreateFileA and
uses WriteFile from application.dll file to store the data.
I have already injected my dll into the exe file, and i am able to catch and replace the
CreateFileA - so that i am not pointing to create a filename but i wanted to redirect the
WriteFile entries to the named pipe.
Looks good, the pipe is created but no data is being sent out - i believe because WriteFile is invoked not from exe file, but from application.dll.
Is there any chance for me to hook into that WriteFile ?
Ps.
I thought that when CreateFile is pointed to pipe, the WriteFile also will store the data there via the Handle..even if invoked from separate dll.

Sometimes this article can help you out: API Hooking Revealed[^]
If you have copy of Programming Application for Windows by Jeffery Richter, it clearly explains about DLL Injection and API Hooking.

Sarath,
thats great, but please read my question.
When a program uses CreateFile from itself ( exe ) - i am unable to hook into that (CreateFile).
When it uses a WriteFile ( which is in application.dll ) i am unable to hook ?
Seems like when a Api call is used by the DLL not EXE, hooking is not possible?
Is there any difference ?

I think you have hooked all the API's used by the exe only. In your case after hooking the WriteFile() function in the exe, you should take each depended dll of it and do the same.

I need some information about deriving a non-template class from a template class (I've already thought about whether I really need to do this, and it is the best solution in my case).
I have a base class which is also a template class:
template <class T>
class Base {
public:
Base();
Base(INT);
virtual ~Base();
virtual INT Base<T>::f();
virtual INT Base<T>::g(INT);
INT n;
T* x;
};
and for its methods I make sure to use the necessary syntax, i.e.:
template <class T> INT Base<T>::g(INT num)
{
// (code here)
}
But I also have some classes which are derived from the template class, such as:
class Derived : public Base<INT> {
public:
Derived(): Base() {};
Derived(INT): Base() {};
~Derived();
INT h(FLOAT);
};
When linking, I get error messages saying there are unresolved externals. Specifically, the INT versions of the template class methods are unresolved.
I haven't been able to find enough documentation on everything I need to do when deriving classes from template classes, and am undoubtedly missing something somewhere. Can anyone help?
Thanks!

the following lines are wrong:

Is it a typo?
