Reflection onto Assemblies with dependencies

MrEyes6-Oct-05 5:56

I have an assembly that is in the GAC which is using Reflection code to call a second assembly located elsewhere.

This second assembly has various dependencies, and for various reasons I dont want to GAC it or any of its dependencies.

The problem I am having is that while I can load the second assembly fine (by providing the full path to the Assembly.LoadFile(...) function, when I Invoke one of its functions I get a exception indicating that one of the dependencies cannot be found.

Is there anyway I can solves this problem without adding the second assemblies and its dependencies to the GAC??

I think the key here is the intellisense comment on the Assembly.LoadFile(...) function :

"..loading the assembly into the domain of the caller..."

Considering that the reflection code is called from an assembly in the GAC, does this mean that a virtual copy of the loaded assembly is placed into the GAC directories behind the calling assembly

Reading the documentation is always wonderful. Smile | :)

I would recommend rereading the MSDN entry on the Assembly object. From the docs:

Do not use LoadFile to load assemblies that you want to execute. LoadFile does not load files into the LoadFrom context, and does not resolve dependencies using the load path, as the LoadFrom method does.

LoadFile is strictly used to inspect an assembly on a file system. This is handy when you want to "look" but not actually run anything in an assembly. It does not load dependancies or do any other checking and hence is unreliable for execution.

P/Invoke

Hello,
could anybody help me, please?

How do I do the P/Invoke of the following function (from TTNCom.lib of TomTom SDK)?

static INT GetSdkVersionInfoV01(TNavVersionInfoV01& aVersionInfo);<br />
<br />
struct TNavVersionInfoV01<br />
{<br />
  char iVersion[16];<br />
  INT  iBuildNumber;<br />
};

I've tried:

[DllImport("TTNCom.dll", EntryPoint = "?GetNavigatorVersionInfoV01@CTomTomNavigatorCom@@SGHAAUTNavVersionInfoV01@1@@Z")]<br />
extern static int GetNavigatorVersionInfoV01(ref TNavVersionInfoV01 aVersionInfo);<br />
<br />
public struct TNavVersionInfoV01 <br />
{<br />
  char[] iVersion;<br />
  int iBuildNumber;<br />
}

but when calling it like:

TNavVersionInfoV01 nv = new TNavVersionInfoV01();<br />
<br />
int ShowTT = GetNavigatorVersionInfoV01(ref nv);

I get System.NotSupportedException.

There must be some problem with marshalling of types ... Confused | :confused:

Thanks anyway,

Honic

Hi!
Besides the fact that I don't know if your EntryPoint is correct (does it work if you leave out the EntryPoint parameter altogether?), you'll have to specify the size of iVersion for marshalling.
Right now you're just saying it's an array of char (without any size given), but the original declaration says it's a char[6].

Try this struct declaration:

public struct TNavVersionInfoV01
{
  [MarshalAs( UnmanagedType.ByValArray, SizeConst=6 )]
  char[] iVersion;
  int iBuildNumber;
}

Hi,
the EntryPoint is correct, there is no problem. But I forgot to mention that it should work under Compact Framework and I'm affraid MarshalAs is not supported there.

Parser replacement target to Dot Net platform

Member 23353326-Oct-05 3:44

We have a voice xml interpreter that uses Xerces parser. The interpreter is developed in pure C++ using Visual C++. We wanted to replace the xerces parser with MSXML parser. We are also planning to recompile the vxml interpreter in the Dot Net platform. I have a couple of questions in this regard.

Question 1: If I choose the latest Dot Net platform that is "Visual Studio Dot Net 2003", what version of msxml parser does it support. What additional measures should I keep in mind when I replace xerces parser with msxml parser and recompile the whole vxml interpreter in the .Net platform?
Note that we dont want to change our interpreter code while shipping it in the Dot Net platform. Isthat possible?

Question 2: What will be the main effort area for replacing the xerces parser with the msxml parser.
Currently we are using SAX techinique, assume that we will also use SAX technique for the msxml parser.

This should probably have gone in the C++/CLI forum...but I'll answer it here.

Is there a reason that you want to use the MSXML parser? If you're compiling for .NET, then you may want to switch the parser to using the .NET Framework's System.Xml namespace. The System.Xml.XmlNodeReader or XmlTextReader objects will give you a SAX interface to the Xml that you've got. Or you could try the DOM interface with the XmlDocument object.

And no, your interpreter code doesn't need to be changed. You'll want to investigate Mixed Mode assemblies. This will enable you to run part of your code as MSIL on the .NET runtime and part of it in unmanaged/native mode.

The hardest part is just going to be getting used to the .NET platform. And maybe the funky syntax for the MC++ code.

Picture a huge catholic cathedral. In it there's many people, including a gregorian monk choir. You know, those who sing beautifully. Then they start singing, in latin, as they always do: "Ad hominem..."

SendMessage return value

status()

6-Oct-05 3:24

Hello,

i'm using SendMessage winapi function in my program like this:

<br />
[DllImport("user32.dll", SetLastError=true, EntryPoint="SendMessage", CharSet=CharSet.Auto)]<br />
public static extern IntPtr SendMessage(<br />
			IntPtr hWnd, <br />
			[MarshalAs(UnmanagedType.U4)] int Msg, <br />
			long wParam, <br />
			int lParam);<br />

So i'm executing it and i want to use the returned value. But it seems that the returned value is a pointer. How can i get the value?

The code is like this:

<br />
IntPtr hWnd = FindWindow("Winamp v1.x", null);<br />
IntPtr lResult = SendMessage(hWnd, WM_WA_IPC, 0, IPC_GETEQDATA);<br />

Hmm, may be the problem isn't in the returned type. But when i try this code in c++ it is working and the return value is correct, but in .NET i'm always receiving 20496

I found my problem. It is in the SendMessage declaration. The parameters should be IntPtr instead long and int:

<br />
[DllImport("user32.dll", SetLastError=true, EntryPoint="SendMessage", CharSet = CharSet.Auto)]<br />
		public static extern IntPtr SendMessage(<br />
			IntPtr hWnd,  <br />
			[MarshalAs(UnmanagedType.U4)] int Msg,<br />
			IntPtr wParam,<br />
			IntPtr lParam);<br />

Small correction:
You _can_ use int.
The only thing that was causing troubles was the long declaration, since longs in .NET are 8 byte and not 4 like WPARAM.

Oh, and the [MarshalAs...] declaration is superfluous, btw.

The following should work:

ArrayList objArrayList = new ArrayList();
objArrayList.AddRange(new int[]{1,2,3,4,5,6,7,8,9});

Most browsers let you save the html code of a page.

If you need to do this programatically, use a WebRequest to get the pages, and just save the response string.

Take a look at the Process[^] class.
The easiest way to execute a program is using its static Start method:
Process.Start("IExplore.exe"); or
Process.Start("IExplore.exe", "www.northwindtraders.com");
