Within VB.NET, trying to find an easy way to in a sense check the check-box "Use Windows to configure my Wireless Network Settings". This is an option that forces windows to use your wireless over third-party programs that may try to steal control. I am aware this requires to have WZC enabled within services and that's something that can be easily accomplished one way or another.
I doubt or rather cannot find a proper registry value or API call to check or initiate such a task.
I would use a registry-recorder to record the changes when manually changing the value, then its a piece of cake to implement the register change in code.
There are plenty programs that can be used to see what changes has been done in the registry, here are one free: http://www.kephyr.com/systemsherlocklite/index.phtml, but google may find more or better variants out there.
With this tool, create a registry dump:
systemsherlock.exe -dump d1.dat -regdirs HKEY_ROOT
Do the change in the wireless network settings
Do a new dump of the registry:
systemsherlock.exe -dump d2.dat -regdirs HKEY_ROOT
And last, compare them and see what has changed:
systemsherlock.exe -compare d1.dat d2.dat

Currently i'm working on a security monitoring app that continuously monitor new processes created.
For that im using wim and event watcher, witch works fine in VB.NET.
But there are 2 features that im missing.
I need to monitor process API calls, and I've been searching the web like mad, and come up empty.
Basically i need to monitor process WaitForSingleObject, LoadLibraryA, CreateProcessW and WriteProcessMemory. And registry access/changes as well.
Im hoping this can be done without a system wide hook, but form what i can find, it cannot be done via WMI.
So the question is, how to, and what can i do with managed code.
I'm gonna focus on the second point as i don't have experience on your first.
For checking if a process is signed i am using the sigcheck.exe from Mark Russinovich, because of the various methods it uses to verify files. Some are catalogsigned, some have the key embedded, there is iirc another weird method. There is no easy way to do it yourself. Had weird false detections with trying self-built methods to cover all possibilities. Hope that info helps
Consider a business scenario in which a third party's Window Application uses F4 key to auto-fill some inputs with previous record details; and management want to stop this. (no code access on this 3rd party application, all users are in domain, and machine is shared between shift-users)
Now, question is, what would be the best approach to disable F4 Function-Key just for this particular application? Writing a process/windows service couldn't works well. Users can kill them from task manager or services explorer.
Any suggestion/Idea ?
There are a couple of ways you could try this :
(a) enter the BIOS setting, and change the "Function Key Priority"
(b) Install a new keyboard driver and use its configuration parameters.
(c) You could map those keys to a program that does nothing. Like : "wscript //b". But, this might affect focus/active window.
(d) Use the Kid-Key-Lock feature : http://www.100dof.com/products/kid-key-lock
Is there an API or way to programmatically turn off an individual, external monitor via Objective-C on a Mac?
I'm looking to write a small menubar application that can control a secondary display (without a physical power button), but still keep the primary monitor in use.
Hunting around the API documentation, I can't seem to find anything, other then reading states. So hoping someone else might have an idea.
You can't "programmatically turn off an individual monitor", it's not physically possible. The most you can do is tell the OS to not use the monitor, but I don't think you can change system-wide settings like that, especially not at the level you're working on (Obj-C).
Looking at the Core Graphics API mentioned in #Halley's comment, try starting with the CGBeginDisplayConfiguration method and see if you can set a display configuration to your liking.
EDIT: Alternatively, you could also use CGDisplayCapture(displayID), which by default fills the captured display with black. You can then
call CGDisplayRelease(displayID) when you want to turn it back on.
It seems to be possible to sleep display so by I/O Kit:

But I am not sure whether it can control single monitors.
If you edit a service in Windows 7 and go to the Log On Tab, there is an option to "Allow service to interact with desktop". I'm trying to ensure that it is set for a certain service using VB.NET. Does anyone know of a way to do this?
Note: Doing this during the install of a program is not an option. It has to be done at run time.
Call ChangeServiceConfig with SERVICE_INTERACTIVE_PROCESS. The benefit of using Windows API is that it should takes care of the notification and consurrency part and invalidate the cache in other programs that uses service controller, and when something goes wrong, you get an error code back. Generally speaking you should not access the registry if you can use API to get/set a setting.
Service configuration is stored in the registry, under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\
With a key for each service.
It appears that the third to last flag within the Type value corresponds to the 'interact with desktop' value.
For example, a service set to NOT interact with the desktop has a value of:
Type REG_DWORD 0x0000010 (16)
whereas that same service, when set to be allowed to interact with the desktop has a value of:
Type REG_DWORD 0x0000110 (272)
I can't say that this is guaranteed as I've not done any testing, but it may be a good place to start. You'd need to restart the service before the changes to this value take effect.
I'm trying to use the mstscax.dll (Microsoft Remote Desktop Control) to login to a Vista machine that requires Network Level Authentication.
I've played around with all the methods in IMsRdpClientNonScriptable4, IMsRdpClientAdvancedSettings4 and IMsRdpClient6. There are a slew of functions that appear that the might enable this.
EnableCredSspSupport
PromptForCredentials
PromptForCredsOnClient
NegotiateSecurityLayer
Unfortunately the MSDN documentation is pratacily useless and I can find no examples for any of these on the web. I know that it's possible because a product called "Royal TS" can connect this way.
One hint is that both "Royal TS" and Vista's Remote Desktop create a authoriztion prompt that looks like the one from CredUIPromptForWindowsCredentials, this makes me belive that i might be able to use a function like that to get the credential and then possibly use PublisherCertificateChain to tell RDP about it.
Any ideas would be helpful.
So if other people find this:
All that needs to be done is EnableCredSspSupport=true, the problem I had was that I was loading the mstscax.dll manually and the version I was using supported the IMsRdpClientNonScriptable4 interface but simply didn't work. If you just load the control normally just setting EnableCredSspSupport=true works fine.
This property maybe help you
RDPControl.AdvancedSettings8.EnableCredSspSupport = true;
In addition, It also depend on your OS support Network Level Authentication or not.

I've never tried to do what you're doing but I suggest you take a look at the following article:
Multi Remote Desktop Client .NET
The projects uses mstscax.dll.
