Hi, I've got a video capture app running and i want to automate the
process of getting the devices. You see, i have a form with three picture boxes
To receive three feeds from a webcam. Now What I want to do
is automate the app to initialize the feeds automatically without having to select
the video device when the app is loading. Now with just one webcam I can do this just fine, but with more than one the select device dialog of the OS always pop up.
Is there any avicap32.dll callback function to do this?
I'm using avicap32.dll as the video library, can anybody help me?

Hi all,
I am trying to retrieve the Disk partitions using the following code lines
foreach (ManagementObject mgmObj in gmtObjo.GetRelated("Win32_DiskPartition"))
{
}
This code snippet works well for user having administrative privileges on the machine.However,user having less privileges it does not retrieve any record.
I have searched through net and got the solution where we have to give the permission to the WMI itself using WMITool.However,this solution seems like not feasible as I can not give the permission to client machine.
I am looking for solution using which I would able to fetch the records irrespective of what user privileges are.Either through script or setting the privileges through code(setting through code might again require admin rights...).
Anybody here had faced this problem before or have solution to this??
Help will be appreciated!!!
Thanks in advance

I'm a student working on a project and I have no idea how to begin.. I want to make a program that works like remote desktop, but instead of being able to access the other user's desktop, you can view their web browser and their activity in it. I want it to work like a messenger program that allows users to like "share" a browser.. I have no idea what to research or where to start... I know I want to write it using c#. Someone told me to try to get it to work through a LAN connection first and then switch it over to work online.. Any advice at all would be really really appreciated..

Research! Look for C# examples that provide some of the same functionality that you want, assess them (do you understand the source, is it reusable etc), and build a bookmark-list.
Next thing you want is to document your research. That will lead to a Definition Study, which in turn leads to Functional Specifications, which in turn lead to Technical Specifications, which may lead to an actual implementation.
Sounds like a lot of documentation, whereas you are looking for code. The documentation is there to prove to yourself whether this is a viable idea, and is a good measurement to decide if you have done 'enough' research. If all looks well and easy on paper, it might just be easy. If it sounds impossible, do some more research or move on to a more viable project-idea.
Hope this helps

Hi,
I have a C++ class that is compiled as a DLL.
now I would like to import it to my C# program.
I know how to import function, but what should I do for importing the class so I can in my C# program create an instance of this class?
Thanks,
|
|

Unless it is managed C++ you cannot import the class. If it is managed C++ then what you have as an Assembly which can be added by adding a reference to it in the project and by putting a using myNamespace at the top of the C# file you want to use the managed C++ class in.

Thanks, but how do I know if it's managed C++.
It was written with Visual Studio 2005

|

hi,
You could try adding a reference to the dll to your c# project. It will fail if it is not a managed assembly or COM component.
Another way would be to try to open the dll with the MSIL disassembler. Again this will fail if there is no CLR header.
Alan.

Something which just came to mind. Would it be possible to have a function which returns a pointer to an instantiation of the class? So would something like this work?
//C++
extern "C" MyClass *GetInstantiation(void);
//C#
[DllImport("MyFile.dll")]
public static extern IntPtr GetInstantiation();
|

yes its possible

I usually create a bridge written in C++ managed which creates one managed class and namespace that could be later imported into C#, but underneath this managed C++ class works with that actual and normal C++ class any way it is expected to work with this class, either I compile them together or I import dll and call this class internally.
This bridge serves several good purposes: to test what actually I need in C# from that C++ class. Only those things pass the bridge. Second the bridge is an excellent place to check if parameters are passed correctly and if some of them have to be arranged differently: pointers, arrays... all need different treatment in C# and C++.
If you don't have this bridge, but you directly call a C++ procedure from C# then you have to think about this inside C# code every time you call a specific C++ function. And then if you want to use the same C++ class again, the same problem. With bridge you just import it and everything is tested.

Hi all,
How can i find out process path?
i am using following code for getting process file name. i need to get the path of that file also. Can any one help me??
Process[] arrProcesses = Process.GetProcesses();
for (int i = 0; i <= arrProcesses.Length - 1; i++)
{
Process objProcess = arrProcesses[i];
if (objProcess.ProcessName == "WINWORD" && !(objProcess.MainWindowHandle == IntPtr.Zero))
{
string FileNameDefault = objProcess.MainWindowTitle;
string[] str1;
str1 = FileNameDefault.Split('-');
// System.IO.Path pt=objProcess.exe
FileNameDefault = str1[0];
}
}
Regards
Lijo

objProcess.MainModule.FileName
Edit: Suggestion: If you are searching for only Winword processes you can use Process.GetProcessesByName to avoid the loop and checking for the particular process name

GetProcessesByName() returns an array, just like GetProcesses() does; it probably will be a shorter array, but you may still want to enumerate it.

Hi,
I have using sockets to communicating with our client applications. In the server application Listener i mentioned backlog 200 but most of the times the connection queue holds below 100 requests only. In this case some times when client try to connect .Net throw an error which says the queue was full. After that Listener will not take any new connections and it just close socket immediatly.
ListenSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any, 4098);
ListenSocket.Bind(ipLocal);
ListenSocket.Listen(200);
ListenSocket.BeginAccept(new AsyncCallback(OnClientConnect), null);
Error: [OnClientConnect]->
An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
I dont understand what is happening there............
Please give me the solution....
friendly,

Hi All,

If you insert ? to the beginning of XML file, XML file will become invalid and you will not be able to parse it. Are you trying to add the <?xml version="1.0" encoding="utf-8" ?> line?

Navaneeth,
my original line is
and i need ?<xml version="1.0" encoding="utf-8">;
small background about what i am doing:
I am creating a xml file in console and trying it save it as XML.
And when i use this XML it gives me an error because char "?" is missing.

Use the XML manupulation classes like XMLDocument. It has got a Save method which writes a XML file.

Follow the instructions in the error message. You need to create an Insert command on the SqlDataAdapter.

In my opinion? No, never.
