Re: I dont get this compiler setting conflict!

/clr is activate via the "use managed extensions" option in the general page.
/RTCx is enabled via C++/Code Generation/Basic Runtime checks.

Looking up the Compiler error code ~~will~~ should give a better explaination too. (in this case it doesnt Dead | X|

In W2K and XP, when you resume after a suspend or hibernate the OS asks you to provide a user id and password. While this is happening, the suspended programs continue to run in the background.

Does anyone know how to detect this is happening from within the program? I'd like to suspend processing in my program until the user has logged on.

Thanks for the suggestion, but that is specific to services. For ordinary programs running on the desktop it always returns 'True'. I ran a test just to be sure.

Thanks anyway,

Oops didnt know that Smile | :)

Will add to my knowledge base! Another suggestion, you can perhaps look if a handle has been created, that failing query the size of the form, if size.empty normally the program is in a minimized state, but u could check for that, it mite be diffenrent in your case.

Thanks again for the suggestion, but no good either. The program runs in what it thinks is a normal environment - it even has a current user even though a log in screen is being displayed!

I guess there might be some kind of system message, but I don't know where to get a list of them from.

After a lot of research I managed to answer my own question. During the log in process the OS displays a different desktop - and that can be detected in a VB.net program as follows...

Declare Function GetThreadDesktop Lib "User32" (ByVal dwThread As Integer) As Integer
Declare Function OpenInputDesktop Lib "User32" (ByVal dwFlags As Integer, ByVal fInherit As Boolean, ByVal dwDesiredAccess As Integer) As Integer
Declare Function GetUserObjectInformation Lib "User32" Alias "GetUserObjectInformationA" (ByVal hObj As Integer, ByVal nIndex As Integer, ByRef pvInfo As Byte, ByVal nLength As Integer, ByRef lpnLengthNeeded As Integer) As Integer

...

Dim MyDesktopName(254) As Byte
Dim MyDesktopNameLength As Integer = 0
Dim InputDesktopName(254) As Byte
Dim InputDesktopNameLength As Integer = 0
Dim StringLength As Integer = 255
Dim UOI_Name As Integer = 2
Dim x As Integer
Dim z As Integer

...

'Get name of the program's desktop
x = GetThreadDesktop(AppDomain.GetCurrentThreadId)
z = GetUserObjectInformation(x, UOI_Name, MyDesktopName(0), StringLength, MyDesktopNameLength)

'Get name of the active desktop
x = OpenInputDesktop(0, False, 0)
z = GetUserObjectInformation(x, UOI_Name, InputDesktopName(0), StringLength, InputDesktopNameLength)

For i = 0 To 254
If InputDesktopName(i) <> MyDesktopName(i) Then
'Here if the program is not running on the active desktop
'Eg. if login screen is showing after hibernate or suspend,
'or a password-protected screen saver.
End If
If InputDesktopName(i) = 0 Then Exit For
Next

Question on REMOTING

DragonFox30-Jul-04 1:29

Hi Everyone,

I am trying to figure out how to create an application that uses a database. However, I would like my application to be setup in such a way that it can use the data from another person that is using the same software.

Example: (I am a bird watcher) I have an application that tracks all the birds I see as well as the pictures I have of them. All the data is contained in a MS-Access database and is on my local system.

What I would like to do is to be able to modify the "data getting functions" in such a way as to be able to get the data from another person's computer who is running the same application. Also, That other person would be able to read information from my database.

All the examples I see in remoting are related to having a client and host that are 2 different computers. There is no example of being able to remote on to yourself. The fact that your class has to be registered as client or host exclusively suggests that it cannot be done.

Anyone have any clues ?

Thanks
Gary

Just for the fun of it !

Remoting is used all the time under the covers on the same PC. Examples are scarce though Frown | :(

Have a look at appdomains perhaps for a starting point.

No, if it is like that there is no question of remoting is extension of DCOM. u can write client and server applications in the same PC or in different PC's.

Hi
See we can do remoting on the local system itself, Remoting nothing but transmission of information from one application domain to another application domain . So for that u definately need a hosting application that host u r remoting object and one or more client applications that will make use of u r remote object.

i am not able to understand what is u r requirement, can u make it more clear?
it might be like this
u have to decide which one is u remote object and u r saying that accessing of the data from other persons database so u have to make other person system as u remote object that will make to way communication.

Hi,
what I want to do is an application that uses a database.

The application would not be a client/server based in the sense that the
server would not be available unless the client launches his application.
This would "activate" the server part of the application and make it
available to anyone who can reach it (controlled by the client, if he wants
to let the requestor see his data).

Now the client, on normal startup, would just see his own data, via the
local access. But if he wants, he would request to change the "connect-to"
location to connect to somebody else's database.

I had this going via a thread and a network service that I created. But
in the .net environment, you need to have the server-class AND the
client-class both registered. If it's registered as a client, then you
cannot use it as a server.

What I will need to do, of what I can tell, is create a second .exe or
.dll file and run it as a seperate process via process control.

I will be looking into this later this week... I am cuaght up with other
stuff at the moment.

Thanks for your input.

Hi Friends

Here is a simple question in which im confused.

when we build our ASP.NET project . Does it get compiled or gets interpreted.

I know that many of us think that it is compiled but when i build my project i get the error one by one.
this means that it is interpreted.

If any one knows what is this please do let me know.

all the code is compiled. when is a different story. C# source behind file are compile in the dll, but aspx and controls are compiled on 1st access, hence the reason u can replace them at runtime.

Building a ASP.NET dll is a bit more tricky, and beyond the scope of normal human beings Poke tongue | ;-P

(but its all compiled)
