multiple instances of the same dll using appdomain - C# Discussion Boards

Remote Desktop like component

I'll help you out, although C has little to do with C#

.cpp is indeed associated with C++. If you do not have a solution then make one, then add the files in and hope things work. You might want to go to the project settings to configure additional include directory, libraries, and other settings. I cannot help you any further since I dont know what files you are working with.

If you need additional help getting things working I suggest you post in the C++ forum.

Thanks, yes. I was opening the wrong type of project. Now I just have to figure out why these two files are is missing. The debugger chokes on includes called wx/wxprec.h and stdafx.h.

There is a stdafx.h in a subfolder, but adding it to the project doesn't fix the problem.

I'm going to take this over to the C++ forum. Thanks for your help.

No, cpp stands for C++. A C++ program rarely uses .hpp instead of .h.

Try creating a console application and then adding these files to it.

Where did these files come from ? Why are you trying to compile them outside of a project, surely they will end up in a project, can't you compile them there ?

I'm going to be working on a fairly complex application soon and one of the features I'd like to integrate into it is a remote desktop/vnc type control. I've done a couple searches on google but didn't come up with much.

So basically I'm looking for a .net component to use in a WinForms app. The majority of the systems this will be used are running XP Pro so might there be a way to integrate RDP as an ActiveX control?

I'm just pulling ideas out of thin air Confused | :confused:

at the moment so any ideas or suggestions would be great.

Thanks

multiple instances of the same dll using appdomain

8-Sep-05 8:49

I dont have any experience with this but I tried searching for "terminal services activex" and found an interesting article on "Remote Desktop ActiveX Control Interface" from Microsoft ... seems promising.

Hello,

I'm looking for a way to load multiple instances of the same dll into one c# application.

The facts are:
1) The assembly is third-party, so recompiling/modification is not an option!!!
2) The assembly is programmed in C.
3) It is to be used for COM-port communication.
4) Different instances of the assembly is needed for binding separate COM-ports.
5) Only one port can be bound per loaded dll.

I've read a solution on this site on how to dynamically load dll's from C# by using the win32 LoadLibrary/GetProcAddress etc. Pretty cool though, but it would involve the ugliness of renaming the original dll for every new instance I need and a somewhat cumbersome native generic invoke method.

I'm a basically looking for a way to load the same dll into different AppDomains without it being domain-neutral. Is there a way to ensure that a dll (and its dependency closure) is NOT to be shared among the different AppDomains (to the effect that each AppDomain has its own instance of the assembly)?

Any suggestions would be appriciated.

I think the only way you will be able to do this is using a multi-process approach and using .net remoting or some other IPC mechanism to communicate. AppDomains are .net only and P/Invoke will still end up using LoadLibrary in the end.

SourceSafe with C# Standard

I have Visual Studio C++ V6. After updating with SP6 my SourceSafe became V6.0d. Fine.
Now ... I just bought C# Std and guess what? it won't use my SourceSafe!

C# actually tells me I've got SourceSafe Version 4.xx and I should upgrade to version 5 or higher.
My SourceSafe About dialog says I've got V6.0d.

Is there any way Visual Studio C++ V6 SourceSafe (or other SourceSafe?) can be used with C# standard?

Many Thanks Cry | :((

AFIAK things should work. SourceSafe hasn't had an update for a while. 6d should work fine. Try reinstalling SourceSafe.

OK thanks for that. I will try but I doubt it will work. Scouring the web seems to indicate that SourceSafe cannot be integrated with C# .Net Standard ... unless somebody out there can definitely say otherwise.

You know you might be right about standard edition. I personally never used standard.

.NET Remoting question

Asad Hussain8-Sep-05 6:02

I'm new to remoting and not very articulate so bear with me here. I have an object that needs to be queried by a remote client but it inherits from some other class already.

public MyClass : SomeBaseClass
{ 
  public string GetName { return "name"; }
}

So I made a remoting object like so

public class RemotingObject : MarshalByRefObject 
{
  private MyClass c;
  
  public RemotingObject( ) { }

  public setClass( MyClass start )
  { c = start; }

  public string GetName( )
  {
    return c.GetName( );
  }
}

and a server like so

public class RemotingServer
{
	public RemotingServer()
	{
		TcpChannel channel = new TcpChannel( 8080 );
		ChannelServices.RegisterChannel( channel );
  
		RemotingConfiguration.RegisterWellKnownServiceType( 
			typeof( RemotingObject ), 
			"RemotingObject", 
			WellKnownObjectMode.Singleton );
	}
}

My question is that how can I pass a MyClass object to the remotable object after it is created? Is is possible to pass it in the constructor of the remotable object?

Thanks.

A remote object is like another object, you can indeed pass it as a constructor parameter.

Winforms Datagrid New Row

I have an typed collection wich is bounded to datagrid control like this:
dataGrid1.DataSource = collection;

How to disable 'new row' in DataGrid ?

CurrencyManager currencyManager = (CurrencyManager)this.BindingContext[this.dataTable];

if ( currencyManager != null )
{
((DataView)currencyManager.List).AllowNew = true;
}

Hy, 10x for response,
but I have a collection bounded to Datagrid control not a DataSet/DataTable

I am using a collection called "GridLinkedListCollection"

this.globalEntitySearchGrid.DataSource = this.linkedList;
this.globalEntitySearchGrid.AllowNavigation = false;
this.gridTableStyle = new DataGridTableStyle();
this.gridTableStyle.MappingName = "GridLinkedListCollection";

and the new row addition is disabled. Are you binding your DataGrid with code similar to above?

Are you implementing IBindingList?

airbus3808-Sep-05 9:02

8-Sep-05 9:02

Yes, indirectly.

My collection is derived from CollectionTemplate (I use ORM.NET from Olero) base class collection witch
implement IBindingList (is true).

I just want that DataGrid to do not display new row.

Since your collection imp-lements IBindingList, the property AllowNew may be available to you.

http://msdn2.microsoft.com/en-us/library/dx7zc0k8(en-US,VS.80).aspx[^]

Don't cast it to DataView in the code snippet.

Hope this helps.

This line
((DataView)currencyManager.List).AllowNew = true;
generate an error: invalid cast !
