Hi,

i need highly optimized image(bitmap) processing classes. There are lots of scaling, shadowing, blurring, warping and pixel-manipulating operations for my OwnerDrawn Inerfaces. I can use GDI / GDI+ (when XOR mode is possible again) / DirectDraw,Direct3D or the Intel IPP Package(comparatively cheap). Which is the best one? I use only INTEL processors, so the CPU dependence (IPP) does not matter.

Thanxs !

Soap Tookit 2.0 and Soap_Core.msm

Hi,

I'm trying to deploy my application that uses the Soap Dll's ( VC++ 6.0 application that calls a web service in a server), ... the problem that I have on clients with 98:

- If I install IE 6.0 and the Soap Tool it all works fine ( altough... the user becomes a bunch of programming tools .. tracers and... Frown | :-(

).

- If I try to install IE 6.0 and then soap_core.msm, it doens't work at all Frown | :-(

, in theory soap_core.msm should be what I need to deploy my application but... what I'm missing here ?

Greetings
Braulio

PS.: Is not very professional to install on the clients machine a Trace Utility, WDSL Generator, and documentation XDDD...

Hi all,

I have a dialog with the followings:

1) it is a modal dialog
2) it is always on top
3) it has no frame (style = popup, border = none)

my question is this, when the dialog has focus (which means i am clicking over it or moving my mouse over is) i want to do one thing, but when the focus leaves the dialog (click somewhere else, or move mouse somewhere else) i want to do something else.....

i tried to catch these messages and it didn't work properly:
1) WM_SETFOCUS/ WM_KILLFOCUS
2) WM_ACTIVATE / WM_ACTIVATE_APP

can any1 help me here?

thanks in advanced

Yaron

Try SetCapture to get mouse input even if it's outside of your dialog.
To act only once when mouse cursor leaves dialog area try to catch WM_MOUSELEAVE, WM_NCMOUSELEAVE.
Hope that's what you need.

In your derived class MESSAGE_MAP section

ON_MESSAGE(WM_MOUSELEAVE,OnMouseLeave)

I want to do some test about keyboard loging without using hook api. in the following codz, i hope when i press Esc key, the prog will com to an end. but it seems PeekMessage() will never work, always failed. How could it be? Thanks a lot.

#include "windows.h"
#include "stdio.h"

void main()
{
MSG msg;
char buffer[10];
int i, ch;

while(true)
{
if( PeekMessage( &msg,
NULL,
0,
0,
PM_REMOVE))
{
if( msg.message == WM_KEYDOWN && msg.wParam == VK_ESCAPE) break; //Esc pressed, then quit

printf( "Enter a line: " );

/* Read in single line from "stdin": */
for( i = 0; i < 9; i++ )
{
ch = getchar();
if(ch != '\n') buffer[i] = (char)ch;
}

/* Terminate string with null character: */
buffer[9] = '\0';
printf( "%s\n", buffer);
*buffer=NULL;
}
else
printf("peekmessage failed...\n");
Sleep(3000); //ensure there is enough time for keyboard operations
}
}

Or even simpler:

if ( SHGetSpecialFolderPath( NULL, pszMyDocFolder, CSIDL_PERSONAL, FALSE ) )
    return pszMyDocFolder;

or:

if( SUCCEEDED( SHGetFolderPath( NULL,
                                CSIDL_PERSONAL,  // same as CSIDL_MYDOCUMENTS. SHGetFolderPath() & CSIDL_MYDOCUMENTS needs latest SDK
                                NULL,
                                0,
                                pszMyDocFolder
                              )
             )
  )
{
    return pszMyDocFolder;
}

depending on which version of the SDK you have installed.

How to get the current traffic bandwidth of computer?

Hello, everyone!

I want to get the current bandwidth (input and output respectively) of a Windows system, for example, 20.2kB for input and 30.1kB for output.

Where can I find some sample codes?

Thanks in advance,
Geo

For Windows NT-based systems, look at the Performance Data Helper API. You'll be interested in the Bytes Received/sec and Bytes Sent/sec counters on the Network Interface object, I think.

Thanks, Mike buddy!

I have taken some time to read the API you introduced to me. They are really helpful. I am using the following source code to get in/out traffic bandwidth, but the output is always zero. Can you help?

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;
}

mmc dialog windows

Hi, I'm having trouble adding a dialog to my mmc snap-in.
the problem occus when I create a dialog in response to a menu command. while the dialog works fine if the menu command is from the context of a top-level scope item, the actual dialog is offset within it's own frame if it comes from a second level menu item.

any help would be much appreciated

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
