Hello, everyone!
When using the following program to check in/out band width of a network adapter, the band width is always zero. Anyone know how to resolve the trouble?
Source Code:
----------
#include <windows.h>
#include <conio.h>
#include <stdio.h>
#include <pdh.h>
#include "iphlpapi.h"
#include "Iptypes.h"
#include "Iprtrmib.h"
#pragma comment(lib,"iphlpapi.lib")
int main (int argc, char** argv)
{
unsigned long pOutBufLen = sizeof (IP_ADAPTER_INFO);
IP_ADAPTER_INFO AdapterInfo;
memset (&AdapterInfo, 0, sizeof (IP_ADAPTER_INFO));
MIB_IFROW ifrow;
DWORD last_sent, last_recv, current_sent, current_recv;
DWORD diftime, dlwinspeed, upwinspeed, dw_refreshtime;
if( GetAdaptersInfo(&AdapterInfo, &pOutBufLen) != ERROR_SUCCESS ){
printf("Could not open default interface!");
return ( 0 );
}
ifrow.dwIndex = AdapterInfo.Index;
if( GetIfEntry( &ifrow ) != NO_ERROR ) {
printf("Could not open default interface!");
return ( 0 );
}
while (1)
{
current_sent = ifrow.dwOutOctets - last_sent;
current_recv = ifrow.dwInOctets - last_recv;
last_sent = ifrow.dwOutOctets;
last_recv = ifrow.dwInOctets;
printf ("Octs out: %ld\n", ifrow.dwOutOctets);
printf ("Octs in: %ld\n", ifrow.dwInOctets);
diftime=(GetTickCount()-dw_refreshtime);
dlwinspeed = current_recv/diftime;
upwinspeed = current_sent/diftime;
dw_refreshtime=GetTickCount();
printf ("Band in: %ld\n", dlwinspeed);
printf ("Band out: %ld\n", upwinspeed);
Sleep (5000);
}
return 0;
}
----------
Thanks in advance,
Geo

When I compile my .exe the compiler give me this error:
"error LNK2020: unresolved token (0A0000FD) SysStringByteLen"
"error LNK2020: unresolved token (0A000101) SysAllocStringByteLen"
This problem occur when I set the proprety project "Treat wchar_t as Built-in Type" (in th C/C++\Language Menu) to "No". My project use Managed Extensions and C# class.
I try (how is described in MSDN) to include "oleauto.h" and to link oleaut32.lib, but it was all in vain.
Thank you very much for any answer.

Anyone knows how SysIternal's FileMonitor gets it's information?

hey peter 
this is a good question, and i have the answer.
it is using a file system filter hook!
you can email me if you want further help...

Not exactly (other than what is shown here), but I've e-mailed Dr's Russinovich and Cogswell in the past and they have been helpful. They obviously don't give away trade secrets, but if something is available and it is just rather hard to find, it shouldn't be a problem. They might even point you to one of their books.

And you sent this to me because?? I know what their site says, which is why I referenced it in my reply. If that paragraph is a good enough description of what is going on, fine. If not (which I assumed was the case), contacting the author(s) is the way I'd go.

I've ben pondering your sig for a while now.
Either you're tricking me - or there's something I'm missing 
would "two birds" be an inappropriate answer?

Hello!
How is the memory allocated when using new? The problem is that I have to allocate many single entries which are very small and I don't know now how that will affect memory consumption and speed.
For example:
Will
int i;
for(i = 0; i < 1000; i++)
p[i] = new DWORD[1];waste much memory than if I would use
p = new unsigned char[4000]; Actually the entries aren't that simple and the code above should be meant just as an example. If I want to allocate lets say 16 bytes, does the memory allocation routine round that number up somehow and allocate more than I need?
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??
(doesn't work on NT)

i don't know how it is alloced, it's heap memory, so prolly by malloc.
use the debugger and follow the new call to find out, how it works!
Don't try it, just do it!

The first example will eat *much* more memory than the second.
Heaps are typically organized as a list of memory blocks that are either used or available. Since you might want to free the allocations in the first example individually, it needs to keep some extra information for each allocation.
The first one can slow down a program considerably, first because of memory footprint, second because searching for a matching free block takes longer (because there are much more blocks to look at). Many allocations of that small size are not recommended from the normal heap.
However, you can use a custom allocator that better fits your needs.

Ok, thank you  Then I will have to do some sort of custom allocator.

Btw: der Link zum Agile Programming tut nicht mehr direkt
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Hi guys,
I can't believe how much hassle I'm having trying to trap a user's confirmation of a CEdit entry. I have a toolbar with a CEdit control on it. Ideally the user should only input numbers.
What's the best strategy to catch the obligatory ENTER confirmation? I create the toolbar and CEdit control in CMainFrame, but CMainFrame doesn't get any of the key notifications.
Any ideas?
Many thanks,
S

Do you get the key notifications in PreTranslateMessage of your CMainFrame before they go to the edit control etc. If you do, you can trap and process them there.

#include "ColourSelection.h"
ect. until
void CProjectView::OnInitialUpdate()<br />
{<br />
CFormView::OnInitialUpdate();<br />
GetParentFrame()->RecalcLayout();<br />
ResizeParentToFit();<br />
ChangeColour();
<br />
}<br />
<br />
void CProjectView::ChangeColour()<br />
{<br />
CColourSelection *pSelector = new CColourSelection(this);<br />
pSelector->Create(CColourSelection::IDD, this);<br />
pSelector->ModifyStyle(0,WS_VISIBLE);<br />
delete pSelector;<br />
Invalidate();<br />
}
I can't understand why the dialog box ISN'T opening
Anyone has any knows the correct code or what is the bug in my code?

You are destroying immediatly the dialog box you have created. Destroy the object in CColourSelection::PostNcDestroy instead.
void CColourSelection::PostNcDestroy()<br />
{<br />
delete this;<br />
}

I've tried that but dialog is still not opening.

I want to extract values from dialog object priorto destruction in my CFormView class. Hence, it's not appropiate for CColourSelection to "commit suicide".

You have also to call pColourSelection->ShowWindow(SW_SHOW);
Are you sure the problem doesn't come from your CColourSelection class?
Alton Williams wrote:

It's not exactly a suicide. The PostNcDestroy method is called after the destruction of the dialog box (destruction != deleting). This method allows to free the memory you've allocated with the new CColourSelection.
Check your mail, I've send a small app showing the use of a modeless dialog.

How do I make them disappear...
I've tried:
cs.dwStyles = ~ WS_VSCROLL;
But it causes the framework to not create a document or something like that...
Any ideas how I can go abouts doing this...?
Thanks

Are you sure the scrollbars are carried by the CMDIChildFrame, and not by the embedded view contained in the Child Frame?
What kind of view do you use?
