u know what I can do here?

API automatically generated by the type lib discoverer comes short in many places, including that one. In fact, you need to know to hack the C++ IDL interface counterpart before you get the C# stuff working.

For your issue, the simplest thing I can see is as follows :

short i = 2; // example
object oi = i;

frame f = X.frames.item(ref oi);

Start ILDASM via code?

hi i use ildasm.exe in my tool , how should i do to start it via the .net environment variables?
currently my code looks like

<br />
Process p=new Process ();<br />
p.StartInfo.FileName =@"C:\WINNT\Microsoft.NET\Framework\v1.0.3705\ilasm.exe";<br />

i need to be able to start it via the environment vars and not use a hardcoded path.
so how do i access the environment vars and how would the aboce code look with the environment vars in it?

Call this function[^] via DllImport.

[edit]And I never tried it, but you can try the RuntimeEnvironment.GetRuntimeDirectory method[/edit]

oke this solved it halfway..
i need the path for ilasm.exe to... and for some reason ilasm and ildasm are located in differet folders.

"C:\Program\Microsoft Visual Studio .NET\FrameworkSDK\Bin\ildasm.exe"
and C:\WINNT\Microsoft.NET\Framework\v1.0.3705\ilasm.exe

why?

RuntimeEnvironment.GetRuntimeDirectory () returns the path where ilasm is located , but how can i get the other path to? and are they always located at different locations?

Because ILDASM is a programmer tool, it is located on the Framework SDK path, not in the Framework path.
I'm not sure if this is the right way, but you can obtain it at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\sdkInstallRoot

Looks like that would only be part of the SDK. So that wouldn't work if you were installing to a box with only the runtime.

can i execute "vsvars.bat" first?

vsvars.bat is tha batch file that registers the .net environment variables .
so could i somehow execute that batch in the context of my program so my program can retrive the paths from the environment variables then?

i actually peeked inside a quite wellknown obfuscator (and they use ilasm and ildasm)
and they retrive the path to both of them via the environmentvariable "path" , but that variable dont contain the .net paths unless vsvars.bat have been executed.
(they also display a mysterious dos window before their app starts , and i beleve they actually executes vsvars.bat in there somehow)..

so any ideas how i could start that bat file so that the vars are visible to my app?

Well, there are a couple problems with that. That batch file is only included with the .NET Framework SDK. End-users will only have the .NET Framework Runtime. So they won't have ILDASM or VSVars32.bat.

And, you can run VSVars32.bat, but why not just hardcode the path? I don't think it's gonna change until you upgrade to another .NET Framework version.

internet connection is up

I detect the internet connection with the following method
//*************************************
try
{
server = DNS.GetHostByName("www.yahoo.com");
}
catch(Exception)
{
Console.WriteLine("Internet Connection not found"); // fail
return ;
}
//***********************************************
But it takes times to find if internet connection is up. I need a faster method.
Is there any?

The internet doesn't really work like this.

Try running pathping www.google.com at your command prompt. You could try running a trace like this from within .NET and look at the second or third hop but it wouldn't be very reliable.

To capture the ouptut of pathping off the command line see my other post at http://www.codeproject.com/script/comments/forums.asp?msg=375367&forumid=1646#xx375367xx[^]

No. Bad. You can't ping someone else's website as part of your application or service unless you have an agreement with them. There is such a thing as a ping attack. ibm.com no longer responds to ping, for example, because people were using it in this way. If google decides to do the same, his app won't work anymore. Your solution is good if his app is noncommercial or not used by many people.

You need to use the CopyTo() method of the FileInfo Class.

foreach (FileInfo file in filesInDirInfo)
{
file.CopyTo(newDirName);
}

I use a DataSet load a DBtable,and I want to know how many memory were used by the DataSet object.
sizeof keyword and System.Runtime.InteropServices.Marshel.SizeOf method can only be used for unmanaged objects.

how can I get a reference type object memory size???

You can do something like this:

     DataSet ds = new DataSet();
IntPtr p = Marshal.StringToHGlobalAnsi(ds.ToString());
MessageBox.Show("Size: " + Marshal.SizeOf(p));
Marshal.FreeHGlobal(p);

[EDIT] On second thought, that is only giving you the size of a string. I will have to look into this.[/EDIT]

convert a object to string and get the string size,I have also felt that is a way.But some object contents can not conver to string ,you can just try this
byte[] bytelist=new byte[10]{1,2,3,4,5,6,7,8,9,10};
bytelist.tostring()=="byte[]" not the realy things we want. "12345678910"
so tostring can not get the size of a ref object :$
my method is write the object in to a memory stream and get the stream.length.
I feel some silly about this way，but where is the right way??
you can not get a object memory size in .net??? It means I made a world but I don't know what is it like!!! my god!!!!!!!!!!! Dead | X|
