See http://www.codeproject.com/internet/getmac.asp?df=100&forumid=2459&exp=0&select=47194#xx47194xx

maybe it'll help.. Keep a list of mac addresses in memory and periodically check if the list is up to date

I don' t know if the problem was clear. I don't want to remove the ethernet-card. I will remove the cable from the Adapter. In this case windows shows a tip text message in the right bottom corner.
I thought that I can caught this windows message.

Add 1st project to the second projects solution. Now from the resource view -> Drag and drop the required *Dialog* between the projects. Remember to hold the "Ctrl" while dragging.

I assume you have a class connected to the dialog. I also assume that it is an MFC project. I also assume it is VC6.
Right-click on the dialog class. A menu appears. Click "Add to Gallery".
Then in the other project, go to Project->Add To Project->Components and Controls. Then open the folder for your old application in there. It should have a file called: xxxx.ogx.
Add it to your project. It adds the class, as well as the dialog resource.

this is this.

I have project wich is dependant on another project. I've set this in the Project>Dependancies. Project P2 is dependant on project P1. P1 contains Release and Debug configurations (builds P1.lib).
P2 contains Debug, release, Release 2 and release 3 configurations.
Where to specify that for example P2/release3 is dependant on P1/Release ?
For Release 2 this is working good, but for release 3 it's trying to build and link it with debug version of P1 althought I've used release 2 as original when I was creating release 3. I didn't change anything after creating release 3!

Any ideas ? Thank you !

MFC: Use same menu for mainframe and childframe

Wim Jans3-Jul-05 23:18

3-Jul-05 23:18

Hello,

I'm having a bit of a problem using the same menu for my mainframe and childframe.
Basically I don't need the menu that comes with the childframe.

In my mainframe menu, I'm dynamically building one menu entry, and I don't want to do this processing for every child window I open, that's why I want to use the mainframe menu for the childmenu.

Is there a way to prevent loading of the childframe menu?

I tried to load the mainframe menu in the OnCreate Handler of my childframe, but that doesn't seem to work:

<br />
int CChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) <br />
{<br />
	if (CMDIChildWnd::OnCreate(lpCreateStruct) == -1)<br />
		return -1;<br />
<br />
	CMDIFrameWnd* frame=(CMDIFrameWnd*)AfxGetMainWnd();<br />
	CMainFrame* mfrm;<br />
<br />
	mfrm=(CMainFrame*)frame;<br />
<br />
        CMenu NewMenu; <br />
	NewMenu.m_hMenu=mfrm->m_hMenuDefault;<br />
	ASSERT(NewMenu);<br />
	SetMenu(NULL);<br />
	::DestroyMenu(m_hMenuDefault); <br />
	SetMenu(&NewMenu);<br />
	m_hMenuDefault = NewMenu;<br />
<br />
	return 0;<br />
}<br />

Just do what I do - remove the second menu from the project entirely. When MFC tries to swap menus, it
fails, and gives up with a TRACE complaint. But my first menu is untouched. You just have to make sure
it has all the menu options you'll want on it, as you won't be swapping depending on situation.

Iain.

developing software for windows server

Hi all,

Just wondering if anyone can point me in the general direction of some resoures relating to developing software for Windows Server 2000/2003. I'm developing a back-end processing application that I'd like to run on Windows Server. Basically, all it does is connect via ODBC to a database, do some statistical analysis, and then append a couple of tables. It needs to do be running constantly to be effective.

Obviously it's going to be a little different that the Windows front-ends I've been developing thus far. It's for the banking industry, so has to be fairly compliant with standards and fairly robust too. I guess running the app as a console app, or as a windows service, would be the way to go... anyone got any ideas?

Cheers,
Ritcho

Help finding hook dll

michaelnoam3-Jul-05 22:09

3-Jul-05 22:09

I've written a program that detects the presence of a keylogger on a process ... If I detect one - I wish to scan the process and find the location of the dll who's being using as a logger ..
So far I've detected a logger - and have the list of dll's which are loaded in the process memory .. but how can I know which one is the hook dll ??
I haven't got a clue so far and whereever I look I find myself emtyhanded - can any1 please help me ??

Check for the following string in each of the dll's : "SetWindowsHook"

You can open the dll's in notepad.exe .. most of the compiled code will be garbled .. however imported function names are always in text form.

michaelnoam3-Jul-05 23:41

michaelnoam

3-Jul-05 23:41

thank you for your quick answer -- however ....
The string "setwindowshook"/"setwindowshookex" isn't nessecarely in the dll !!
the function might have been called from an exe file (for a global hook!) and the only function in the dll is the callback function !!
But thank you nevertheless .. I'll try thinking of a function which has to be in the dll ... (b.t.w. the callback function name is up to the programmer - therefor it's of no help!)

munawar19683-Jul-05 23:47

3-Jul-05 23:47

Correct... my mistake.
But the dll must call "CallNextHookEx" ..inside the callback function( whatever the programmer decides to name it). So you can search for this string instead.

What if they use a WndProc that doesn't directly call "CallNextHookEx"? They could pass the arguments back to the EXE file and call it from there. Also, a hook does not even need the DLL file to hook the keyboard. I've writen a hook that is completely contained in an EXE. The way it's done is to use WriteProcessMemory() to copy the WndProc function as well as a control function into the target process. (SAS Window class in my case) Then call CreateRemoteThread() to the control thread to start the hook. The control thread then hooks the keyboard through the WndProc() function. Completely contained in an EXE.

munawar19684-Jul-05 18:20

4-Jul-05 18:20

Your original poser was about about locating the correct hooking DLL.

I assume you inject SAS to hide taskmanager/ capture change passwords sequence/ capture ALT-CTRL-DEL. If so, then the method you use (quite tricky to code correctly) seems ok.
To capture system-wide keybd input for all threads/windows(except SAS input) one can also do without DLLs in far simpler fashion..
