Re: [Mono-dev] BIG ASP.NET BUG : SegFault when sending a Response of a size 120Ko
Le mardi 18 octobre 2005 16:37 +0200, Hubert FONGARNAND a crit :
I confirm it still fails with this test case (updated on bugzilla)
Well, thank you for the fix...
But it fails now with a length200ko
you can try :
private void MyButton_Click(object sender,EventArgs e)
{
int length=20;
byte[] buffer=new byte[length];
Response.ClearHeaders();
Response.Clear();
Response.AddHeader(Content-Disposition,attachment;
filename=\+essai+\);
Response.AppendHeader(Content-Length,length.ToString());
Response.StatusCode = 200;
Response.OutputStream.Write(buffer,0,length);
Response.End();
Response.Flush();
}
you will get :

It's fixed now.
For those of you seeing weird libc errors and xsp dying, please try

[Mono-dev] ImageList patches r51171 and r51889 are not compatible with MS.NET behaviour
Hi, MS.NET ImageList creates handle when you first time retrieve or draw any of it's images. Until that is stores the original image object, after handle creation it uses a native ImageList. It applies size and color depth when handle is created. (This is documented in ImageList.cs.) After handle is created modifying ColorDepth or ImageSize results in handle recreation and the loss of all images. As we don't create any handle at all I decided to create it when images are added and apply size and colordepth when handle is created in other words when they are added. Patches r51171 and r51889 are not compatible with MS.NET behaviour as they don't clear images after handle was created so these modifications should not be preserved. I belive that caching the images until using them is a bad idea as we don't use any native image list and doing time consuming operations at initializaion is better as if you create an ImageList you do it because you want to access the images. If you think caching before handle creation behaviour is important after considering the above things please let me know and I will implement that behaviour.

Re: [Mono-dev] Extern alias patch (latest modifications)
Hello Carlos,
Hey, all the remainign issues are fixed now. All my tests are running
fine and that repeated code has been refactored to report the remaining
warnings in the same place.
It looks good to me.

Hi, Please read my original message one again.:) I explained the differences between MS.NET and this implementation.

Note that on MS.NET if you modify ImageSize after adding images image strips will be added incorrectly (if their size matches new size) or exception will be thrown when creating handle and you will be unable to use the image list. Your patch should not be retained because images are not modified after handle was created the list is cleared instead. And reducing image size without using ReduceColorDepth will result in 32-bit images because of calculated colors.

Re: [Mono-list] Mono and MS Office suite
I'm not sure about this but I would imagine .NET calls Office thru its COM/COM+ layer thru wrapper dll's/PInvoke. Mono should be able to do the same. If you only need to access a few functions then it could be quick to write the PInvokes. If you could make those publicly available then others could add their requirements and soon Mono would be able to do it all as well... ___ To help you stay safe and secure online, we've developed the all new Yahoo!

[Mono-list] Reflection odd exception
Hi!
Iam working with reflection by loading some clases dinamically. This is
a piece of pseudo code:
System.Object[] paramsObj = new System.Object[] {...params...};
Assembly assembly = Assembly.GetExecutingAssembly();
System.Object childWin =
AppDomain.CurrentDomain.CreateInstanceAndUnwrap(assembly.FullName,
managerClass,true, BindingFlags.Instance|BindingFlags.Public,
null, paramsObj, null, null, null);
Everything works fine but one of the classes to load has this method:
bool OnWinDeleteEvent (Gdk.Event e) // Instead of (object o, EventArgs
e).
{
...
return true;
}
I can compile all successfull but in runtime, CreateInstanceAndUnwrap
call launchs this exception:

Re: [Mono-list] Reflection odd exception
I'd hazard a guess and say it's because you don't have a reference to
the relevant Gdk assemblies, or they can't be found in the path, gac
etc. As such when it's creating this object, it's coming unstuck because
that class is using a type that it can't find, hence when you change it
to using types it can find (object, EventArgs), there's no problem.
Either way, you can check the inner exception of that exception to get
the exact error. It'll tell you in there what the problem is, and
whether it is in fact a problem with the call using that type, or
whether I'm way off the mark and it's something completely different :-)
Let me know how you get on.

Re: [Mono-list] Reflection odd exception
Thanks Elliott.
Following the InnerException I have noticed that the exception is
normal, the problem is simple. When trying to Autoconnect (because im
using glade) it searchs for OnWinDeleteEvent(object o, EventArgs e) and
doesnt find it. So the problem is not in reflection neither assemblies,
is my error; When you define signals on glade they must be implemented
in code with expected arguments.
Sorry.

[Mono-list] Parameter passing using PInvoke
Hello, I had the following question regarding parameter passing in PInvoke: If I pass a reference to a structure VIA PINVOKE how do I know the size of the struct in Mono (at emit_native_wrapper ). Mono pushes the address on to the stack but is there a way to retrieve the size of the struct pointed to by the address. mono_marshal_type_size doesnt seem to be the right function..( I am not sure). I dereferenced the pointer at the emit_native_wrapper level as *(sig-params[i])-data.klass and the instance size is shown as 24. where as my structre is just has 4 integer values i.e 16 (obtained using sizeof() in C# code) If I need to copy this structure by value ...what size should I be using = 16 or instance size of 24?? If it is 16 : How can we get this in *mono* (not at the C# program level). Also, If I pass a structure or class by reference through Pinvoke, it would be visible as such to the unmanaged code (without any marshalling). So, if at all Pinvoke does padding , the unmanaged code would access the datamembers as such. Is this correct? Thanks, __ Yahoo! Music Unlimited Access over 1 million songs.

[Mono-list] Jon's reply : Parameter passing using PInvoke
here is Jon's answer to my queries. Any more insights or clarifications are welcome. : I have a structure in my C# code. If in my invocation, I pass a reference to this structure. I want to know the size of the struct in mono. I guess it pushes the address on to the stack. But I want the size of the struct pointed to by the address. Is there any way to get this. System.Runtime.InteropServices.Marshal.SizeOf(). :-) Though there's an important question: is this through P/Invoke or through an icall interface? And is it a C# struct or a C# class? For P/Invoke it doesn't matter, but for icalls the class will have the standard object header, which is 8 bytes in size IIRC. mono_marshal_type_size doesnt seem to be the right function.. Why not? I dereferenced the pointer at the emit_native_wrapper level as *(sig-params[i])-data.klass and the instance size is shown as 24. where as my structre is just has 4 in values i.e 16. Either your structure has padding issues, or you're within an icall interface passing a reference type, thus you'd have the object header to contend with. If I need to copy this structure by value ...what size should I be using = 16 or instance size of 24?? If it is 16 : How can we get this in *mono* (not at the C# program level).
