You don't need a file handle. use the document class's Serialize method instead
the CArchive parameter points to the file being opened (File -> Open) or saved (File -> Save)
void CTestAppDoc::Serialize(CArchive& ar)
{
if (ar.IsStoring())
{
}
else
{
}
}
look up Serialize[^] and CArchive[^] in MSDN for further details

is it possible to mask the properties "Copy" and "Paste"( both by mouse and key board)for a paticular file or folder.ie while right clicking on the file the "copy" and "paste" in the context menu should be inactive.

I have an OCX Control, created with Visual C++ 6.0
I created another new OCX control, modifying the first one with very little changes. I renamed and registered the new one but it replaced the old one.
My problem is that I want both. Renaming the OCX and registering did not help me. How do i do this? Any help is greatly appreciated.
I am sorry if this is a wrong place to have posted this question.

It's not enough to rename it, you have to change it's CLSID too. Use uuidgen.exe tool to generate a new one and then register it again.

Hello everone
I have a file in which the data is stored in hex format,
i need to convert some bytes to DWORD ,exactly 4 bytes
to a DWORD .
i created such a complex statement for that
DWORD biWidth=(unsigned char)m_FileData[18] +((unsigned char)m_FileData[19]*256) +((unsignedchar)m_FileData[20]*65536) +((unsignedchar)m_FileData[21]*16777216);
But i think this is not an effecient way because a heavy arithmatic is used.
is there any other method that is fast an effecient .

Hello,
This is a heavy statement indeed and it can be done much simpler indeed:
DWORD biWidth = *reinterpret_cast<DWORD*>(&m_FileData[18]);
This is the way to go and requires minimal CPU time.
Hope this helps.

BoB i am sorry but ur method
creates error
m_BITMAPFILEHEADER.bfSize = *reinterpret_cast<DWORD*>(&m_FileData[18]);
It worked fine for some file but not with other
, we need to find some other solution

Hello,
What kind of error are you getting? Is m_FileData a BITMAPFILEHEADER? If you, you can use a href="http://msdn2.microsoft.com/en-us/library/wes2t00f.aspx" rel="nofollow">memcpy_s()</a>[<a target=_blank title='New Window' rel='nofollow' href="http://msdn2.microsoft.com/en-us/library/wes2t00f.aspx">^</a>] to copy all contents!

The question is how your statement is handeled by the optimizer.
It's not unlikely that it will use shifts instead of your numbers. Using shifts would probably make the code more effecient.
It's not always true that a simple statement (to write) gives the smallest and most effecient code in the exe file...

Yeh probaly it is true that a simple statement might be not always effecient
but
Its always simple to read & understand , which infact saves lots of time for understanging.
(Code read more times then it is written )

Yes. But the program is executed a lot more times than the code is read... 
|
|
|
|

any way (no one is wright or wrong it the time who governs his statement)
the method supported by Bob
dont work fine for ever file i think
we need to think back how to solve the
problem .

You can try this, if m_FileData is an unsigned char[]:
DWORD biWidth = m_FileData[18] | (m_FileData[19] << 8) | (m_FileData[20] << 16) | (m_FileData[21] << 24);

Hi everybody
I am developing an internet explorer toolband, with many functions, one of them a popup blocker button. I was searching in the examples, but all the examples have ATL or MFC functions, and i need do all that things without using any ATL or MFC functions.
If anybody can helpme i will be gratefull
|
|

|

Without using MFC and ATL
u will need to lots of stuff by ur self.
Must rewrite all the MFC function used in
ur program .
And if u mean to create a pop-up blocker
might be u need to use window messages
so win32 can come to ur resuce.
DLL's can help u but i cant say it for sure

Buddy, it would be easier if you use ATL to develop toolband application for IE, as IE provide automation support for same.
but if you still insist on using pure Win32 Api, here is hint...
you have to create the dll, which contain the Window Which subclass main window for Window Message... also another application which inject this dll into process space of IE ( for that you have to create system wide hooks). not the easy task, but i believe thats the only way to get there.
you have to Hook the system for IE instance...

I'm stepping through my disassembled code:
<br />
*buffer2 = *buffer1; QUESTION 1<br />
<br />
00411AED cmp byte ptr [ebp-119h],0 QUESTION 2<br />
00411AF4 jne main+0D3h (411B03h) <br />
00411AF6 push 411B6Bh <br />
00411AFB call @ILT+555(__RTC_UninitUse) (411230h) <br />
00411B00 add esp,4 <br />
00411B03 cmp byte ptr [ebp-10Dh],0 <br />
00411B0A jne main+0E9h (411B19h) <br />
00411B0C push 411B63h <br />
00411B11 call @ILT+555(__RTC_UninitUse) (411230h) <br />
00411B16 add esp,4 <br />
00411B19 mov eax,dword ptr [buffer2] <br />
00411B1C mov ecx,dword ptr [buffer1] <br />
00411B1F mov dl,byte ptr [ecx] <br />
00411B21 mov byte ptr [eax],dl <br />
QUESTION 1
*buffer2 = *buffer1;
How's this one line translated to this this big chuck of disassembly? (I'm assembly newbie, playing with WinDbg, going thru instruction sets and trying to see things in action)
And, the first line of disassembly is a CMP instruction??
QUESTION 2
00411AED cmp byte ptr [ebp-119h],0 QUESTION 2
okay, is "ptr" a keyword? References? Also, is "byte" a keyword?
I'm looking at WinDbg's manual, the reference is... less than ... For example:
MOV r1, r/m Move with zero extension.
It doesn't state if parameter 1 is source or destination! Any good reference source?
QUESTION 3
How come "main" does not start with address 00000000? #include "stdafx.h" #include <stdio.h> int _tmain(int argc, _TCHAR* argv[]) { 00411A30 push ebp 00411A31 mov ebp,esp 00411A33 sub esp,120h
When I run WinDbg,
ModLoad: 00400000 0042c000 C:\development\Samples\TestDebugger.02\Debug\TestDebugger.02.exe
ModLoad: 77f50000 77ff7000 C:\WINDOWS\System32\ntdll.dll
ModLoad: 77e60000 77f46000 C:\WINDOWS\system32\kernel32.dll
Where's 00000000 to 00400000? What's in it?
QUESTION 4
Where's the "stack", is there a memory address...? Is EBP register the "address" of stack location in process memory/address space? And ESP (stack pointer) pointing to top of stack - but is it just a relative/offset from EBP? I assume EBP is "absolute" address based 00000000 (ie. start of process address space), am I right or wrong?
QUESTION 5
These addresses I see on stack trace, for example, 00411AED, is it "Virtual"? Where's the "zero" point?
Thanks in advance.

So much of code is added to check for runtime errors:
First of all, checks are performed...
00411AED cmp byte ptr [ebp-119h],0 (check if buffer1 has been initialized or not)
00411AF4 jne main+0D3h (411B03h) ( if initialized, check for next value)
00411AF6 push 411B6Bh ( else push some sort of argument for function __RTC_UninitUse on the stack )
00411AFB call @ILT+555(__RTC_UninitUse) (411230h) ( call the error handler )
00411B00 add esp,4 ( pop value from the stack )
00411B03 cmp byte ptr [ebp-10Dh],0 ( check buffer2 )
00411B0A jne main+0E9h (411B19h)(...)
00411B0C push 411B63h (...)
00411B11 call @ILT+555(__RTC_UninitUse) (411230h)(...)
00411B16 add esp,4(...)
Actual work starts here:
00411B19 mov eax,dword ptr [buffer2] (store the buffer2 pointer in eax)
00411B1C mov ecx,dword ptr [buffer1] (...)
00411B1F mov dl,byte ptr [ecx] (copy a byte to dl from address pointed to by ecx)
00411B21 mov byte ptr [eax],dl ( copy a byte from dl to the address pointed to by eax )
done
