Although Chris has answered your question I'd still like to know why and what you think you will find on that address. 
Generally you have no idea where the memory manager has mapped things.
Even if you're trying memory mapped I/O, this will only have a chance to work on a toy-OS as Win98.
Later OS-versions requires a driver executing in kernel mode (Ring 0) to get access to such stuff.

Yup, I know why you asked the questions you did, tox... I know you know what you're doing/knowing. 
I just wanted the guy to start asking himself questions about where he's heading.
We might still learn something...

Have a look at this[^] great article from Anton Bassov.
I found it searching for "physical address" at our favourite site: CodeProject!
However, I suspect since you're asking this kind of questions and are in a hurry, you don't really have the time to read and understand the article. Do it anyway! Tampering with the stuff Anton describes in his article can easily destroy things beyond repair. 
Good luck! ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Nope. Since I haven't done this myself, at least not yet, I cannot tell you what to do.
I directed you to an article that has got something do to with it, but it not be suitable for your situation since apparently you'll need it working on old toy-OSs.
Why not use a later version the OS, at least Win2k. Then it would be a something that would last instead of something very temporarely.
If Win95 is the only option I suggest you use Google to find an article that Matt Pietrek has written about this since Anton claims that Matt Pietrek "has done this for Win95 many years ago".

Hello
I've got problem with blinking window. My application is multi-doc one. One of my view is simple CView with drawing code in OnPaint. This view is repainting every second (when new data is arriving). From this view I'm creating new window which is a child to my current view's frame. Class of this "child" window is inherited by CWnd class. Unfortunately whan my CView is repainting the top window (child window) is blinking. I've used double-buffering technique - and nothing - still the same problem. Here is my code's samples:
1. Making window:
void CBigValueEdit::setVisible( bool b ) {
if ( b == true ) {
if (this->Create( NULL, _T("Test;"), WS_CHILDWINDOW | WS_VISIBLE | WS_BORDER | WS_CAPTION , rect, parent, IDW_BIG_VALUE ) != 0 ) {
this->ShowWindow( SW_SHOW );
this->SetFocus();
visible = true;
calcRects();
setDigitVal();
}
} else {
// wyłącz okienko
visible = false;
this->ShowWindow( SW_HIDE );
this->DestroyWindow();
}
}
2. Double-buffering:
if ( bmpCreated == false ) {
bmpBufor.CreateCompatibleBitmap( dc, rect.Width(), rect.Height() );
vdc.CreateCompatibleDC( dc );
vdc.SelectObject( bmpBufor );
bmpCreated = true;
}
[...]
dc->BitBlt( 0, 0, rect.Width(), rect.Height(), &vdc, 0, 0, SRCCOPY );
3. Making window from main CView class:
ed.setTitle("Set high alarm :");
ed.setRectangle( rect );
ed.setFormat(4,2);
ed.setValue( selectedCounter->getAlarmLowValue() );
ed.setVisible( true );
ed - my class inherited by CWnd...
What;s wrong Where's the catch?
Please - help me...

Have you responded to WM_ERASEBKGND? If you are using double buffering you should respond to this message ans return TRUE, to tell Windows that the background has been erased, otherwise Windows will erase the background with the default brush defined in the windows class.

|

It didn't help... The unwanted effect is that the background window(parent) is in one moment drawn over the child window...

If you are using VC7.0 or later then you have access to the ATL7.0 conversion macros which are much better then the ATL3.0 conversion macros you introduced here. The new versions use the heap instead of the stack for memory allocation so they will not cause stack overflows if used in loops or recursive functions. Read about them in MSDN.
You may be right
I may be crazy

if u r using MFC libraby, u can do this using
char * pName = new char[5];
strcpy(pName,"test");
CString strText(pName);
u can do different conversion using CString e.g: LPSTR, LPCTSTR, LPWSTR
LPWSTR pWstr = (LPWSTR)strText;

I am having a VC++/MFC application it is receiving 10,000 paramaters per second (4 bytes per paramater)
from remote side.I want to insert this data into Oracle server using
ODBC .But any database is having maximum fieldsize of 8000 chars or Maximum 1000
field in one table.
So how do I insert this type of data into oracle or MS SQL server.
I want to retrive this data for further stasstics.Please help
Thanks in Advance

Assuming that you mean the remote side is sending you 40,000 bytes of data per second, and you want to store that data as a distinct row, then you probably need what's known as a BLOB field (Binary Long OBject). If memory serves, then you can only have one of these per row.

How to find the number of lines compiled in C/C++?
Its expected to write/display the numper of line compiled in some std output device or a file at the end of compilation.
Is there any compiler option for it?

Project Line Counter[^] is a powerful open source visual studio add-in.
it's main advantage is that it doesn't count the written code line but the generated code lines...
for instance
printf("Hello World");
and
printf(
"Hello "
"World");
produces the same number of code lines...
they also provide they sources[^] on codeproject...
