Hii all,
I am doing an application which lists the installed softwares in local system as well as remote systems. I can get the installed softwres by reading the registry key value "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall".
But when I tried to read the registry of remote systems using the method "OpenRemoteBaseKey" I am getting an access restriction exception. How can I solve this or is there any alternative method to do this.. Plz help
Thanks in advance

hi Ranjith!
u should have administrator rights for accessing remote registry service on a remote machine ..
by d way why dont u use WMI for getting all d installed applications on local or remote machine..
try using 'Win32_Product' class for getting the list of installed application..
but for this also u should have Administrator Previleges .. on remote machines..

Hii Abhinav
Thank you very much for your reply. Actually I am not familiar with WMI. Anyway I will find it out.
We can add registry permission using regsvr32.exe.
thanks

Hi,
We are developing a software, it has two versions. Trial version and full version. Our
main concern is ensuring customers cannot stick the full version on a file sharing
network or give it away to friends.
If any user buy the full version, he should not be able to give it to another person (It should not work in other machines).
What is the best way to achieve this goal?
Thanks!!

I am working in VS2003 and I created a project which is properly installing, however I need to add 2 more files, but I need them to go directly to the c:\
Currently the setup package is placing those files inside the application folder.
Is this possible?
Thanks

Hi,
i haven't done anything similiar before but i'm sure you can do this with the System.Net.WebClient class. It provides methods like DownloadFile and ReadFile if i remember right. Executing a PHP file isn't anything else than doing a webrequest.
You will never see the php script code on a page (unless php does not work properly) - those scripts will be preprocessed. that means it generates an output which will be send to the one who did the request.
Hence you just have to "behave" like an internet browser and ask for the files.
Since i don't know how to use the webclient class i would suggest you to use google and learn something about it - i'm sure it's the solution for your problem 
Good luck,
mik

Hi.
I'm looking to create an application which is able to dynamically update the display name depending on certain conditions.
I have looked around and there's alot of stuff on creating a new client but not much on interacting with MSN directly
Can anyone point me in the right direction?
Thanks

Two Questions:
1.) Does the image that you set the wallpaper to have to be a bitmap? I know that in the Display Properties you can select a number of different image types, but does Windows convert them to bitmaps before it sets the wallpaper? I ask because if I use a bitmap as the wallpaper I can change it fine, if I use a jpeg it doesn't work (just sets it to a gray background).
2.) Is there a more .NET'ish was to set the desktop wallpaper? I'm currently using P/Invoke with SystemParametersInfo to change it.
I guess that's three questions...Any help on this would be appreciated.
Thanks

1.) Yes it has to a bitmap and Windows converts pictures with another format into a bitmap before it sets them as wallpaper.
2.) AFAIK there isn't.

I have an object class I need to compare for equality, but for which the greater/less than returns that IComparable uses to implement sorting are meaningless. Is there an interface that supports this comparison, or do I have to choose between abusing an existing one and rolling my own?
|
|
|
|
|
Unless you actually need to implement a specific interface, you could just override the == and != operators and the Equals method.

Thanks. I was overthinking the problem.

How can I protect my app in my computer ?
What I mean that how can I start my program
ONLY in my computer.
If someone else try to start the program in another
computer it will not start.
how can I know the unique id of my harddisk ??
and read it from my app .... ?

Use the network MAC address :-
ManagementClass oMClass = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection colMObj = oMClass.GetInstances();
string macAddress = "";
foreach (ManagementObject objMO in colMObj)
{
if (objMO["MacAddress"] != null)
{
macAddress = objMO["MacAddress"].ToString();
break;
}
}
Is there a better, quicker way to get this anybody?
Regards
Malc

Mac addresses are changable. CPU(?)/mobo serials would be a better bet. You'll need to use WMI to get that sort of information.

Is there some reason the XML serializer doesn't support serializing a property whose type is an interface?
Is there some workaround to that, given that I WANT to serialize the property? A work around other than making an abstract class and using XmlInclude?
I don't know the concrete types to serialize, since the object I want to serialize can be defined in a different assembly, and I'd end up with a circular reference. Plus, I don't want to entangle the general purpose class I already have with application-specific implementations of objects that need to be serialized, hence the interface to begin with!

what is there to serialize? Generaly you serialize "data", an interface contains no data.
If you want the data resulting from some method of the interface to be serialized then you need to represent that as a property where the type would be like "string" or whatever. Then the implementation of the property would call the method of the interface to produce the data.

Xml serialization supports serializing objects, not just value types, building an object graph. In this case, the interface is implemented by some classes that I want serialized. Why the serializer can't simply output the type information is beyond me.

Well I hate to point out the obvious but an interface is not a concrete object. Another approach could be custom serialization. Not very difficult.

Hi,
first of all the serialization mechanisms of .NET don't serialize properties - they serialize fields. This is important because not everything which determines the state of an object is accessible via its public interface. Are you getting some kind of exception? If the property encapsulates a field it should work as long as the concrete class hanging in this field is marked with [Serializable].
