Hey lads,
Is it possible to handle a ON_REGISTERED_MESSAGE message in a CWinApp derived class... Keeps giving me static_cast errors... I don't have the code with me now... It was 1am this morning that I was doing it and I didn't even get a chance to look at the messge properly before I fell alseep.
Think it was somethign to do with a cast from CWnd to CWinApp. ON_REGISTERED_MESSAGE a macro that only works with CWnd?
Regards,
Brian Dela

What do you mean by "scan wireless network?"
|
|
|
|
|
What "scan wireless network" means enum all avalible 802.11b wireless network on air.
Sometime, there are more than one AP (access point) or Adhoc network avalible on air. I want to enum all the avalible network and then let user choose to connect one of them.

Take a look at the DDK documentation for 802_11 OIDs. For example, an application can send OID_802_11_SCAN_LIST to ask the miniport driver to do active or passive scan. This list is then returned to the application. User Mode applications cannot send OIDs directly to the miniport therefore you have to have a protocol driver in between to do this correctly. On Xp the zero config service uses a variation of "User Mode I/O" protocol driver (in the DDK Samples) to send these OIDs. Some vendors implement private IOCTL codes in the miniport, in that case application can just send IOCTLs directly to the miniport.

thank you very much, it sounds ok, i will try this way.

Thank you very much for your help.
After I studied some DDK documents, I relized you r a real expert in this area!
Since WinXP introduced a WZC service, does this mean in an XP box, I needn't write a NDISUIO driver myself, instead I can use WZC to do everything I want?
However I searched MS site and found very few information on WZC, almost get no information on how to use WZC service at all. Could you give me more tips?
Thanks so!

Does anyone know how to change network and adapter setting in a MFC program?
It can be easily done by hand, just right click on a network connection and select "Properties" to make changes. However how to do that in a program?
I found a very useful program by IBM, named "Access Connection" (http://www.pc.ibm.com/qtechinfo/MIGR-4ZLNJB.html?doctype=Downloadable+files) can do this. I am trying to write a simular program.
Any help is appreciated!

I hope this is what you are searching ...
eg. to alter the ip - adress
You need to open a key like (for WinNT):
sKey = _T("SOFTWARE\\Microsoft\\
Windows NT\\CurrentVersion\\NetworkCards");
res = RegOpenKeyEx(HKEY_LOCAL_MACHINE, sKey, 0, KEY_READ,
&hKey);
if (res != ERROR_SUCCESS) goto LAB_X;
- Imake it a little bit shorter -
then enumerate the adapter of your choice by
RegEnumKeyEx
the 'ServiceName' - key ist the important - it is something like '{EE0A056F-1C40-4995-B7EB-E47E2C1E0A27}'
combine the path to the service-interface
'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\'
with the '{EE0A056F-1C40-4995-B7EB-E47E2C1E0A27}'
and you will find the key 'IPAddress'.
it is a MULTI_SZ, so editing is a little bit harder - but change the value and it is applied
good luck ...

Thanks but I am not only intend to change the IP address.
I am focused on changing network adapter's advanced settings.
|
|
|
|
|
Metric is in the same folder,
subnetmask, Gateway, ...
just alter the values in the registry. If it works you can programm it ...
Activation and Disabling of the adapter is a little bit tricky.
Maybe I totally misunderstood

Is there any API provide such things? If we have any API it will be more helpful.
or Does it have any other way to do this?
Pls help me.
Thanx in advance.

Hi all,
I am wondering that the following is working. When will the temporary string, created in the constructor, destroyed? After constructor call or after object destroyed? Am I right that c_str() returns only the pointer and not copy char string? Is it a safe program or not?Thanx for your time,
#include <string>
#include <iostream.h>
#include <stdlib.h>
#include <stdio.h>
class a
{
public:
const char * name;
a(const char * name_ ):name(name_){};
void print() {cout<

The 'name' variable belongs to the constructor, not the class itself. Therefore, it will lose validity when the constructor goes out of scope.
|

|
|
Why the program is working? Can you demonstrate this?
|
|
|
|
|
I see nothing that indicates that it won't work (this from just a cursory glance), although I'm not sure what it is trying to do.

Sorry, I have to explain it more exact.
a oa( ((string)"aaa"+(string)"bbb").c_str());
above line passes the pointer on temporary object ( of type const char*) to the constructor. After the end of constructor this object (character seq"aaabbb") should lose validity as you wrote.
But next line oa.print() prints correct object. Is it only a luck, that the memory was not overwritten or temporary object still exists?
If you mean this is a luck, I would very appreciate the suggestion how to demonstrate this

Correct.
Ok, upon examining your code more closely, my last responses were less than accurate. Sorry about that. Some of your code was lost because of HTML formatting so I wasn't sure if the missing code was intentional or not.
The only way to guarantee that the print() method works is to allocate memory to the name member variable and copy the contents of the name_ parameter to it.
