Re: [Mono-list] screen capturing in mono
In theory you could use reflection to call the protected Control.OnPaint
method to trick it into painting on your bitmap's graphics, but it is
obviously a hack, and may have security implications (will almost
certainly require full trust, especially on MS.NET).

Re: [Mono-list] screen capturing in mono
Well there's obviously some way to draw the control ... otherwise it
wouldn't show up normally. Heh. :)
Perhaps just dig into the Mono code, find how the control renders
itself, and expose that through the DrawToBitmap method. You
certainly wouldn't have to implement this for every known control ...
just the specific one you're using. Implementing more, of course,
wouldn't cause anyone to complain.
Of course that is .Net 2.0 as Sebastien points out and you've stated
that isn't an option.

Re: [Mono-list] screen capturing in mono
Eric,
There's no alternative to p/invoke - even if you used 2.0 you would only
be calling a method hiding some platform specific p/invoke calls.
Now using 2.0 may not be an option for you, but that doesn't prevent you
from using CopyFromScreen. Why ? because it's open source :-)
Just create your own library using Mono source code for CopyFromScreen
(and the code it depends on) or include the source in your own project.

Re: [Mono-list] screen capturing in mono
The problem isn't resizing - I don't have an original bitmap to resize. The
problem is that I have a control that I want a screenshot of. So, I'm
trying to create a Bitmap from whatever is appearing in the control.
I pass the control in, then I call control.CreateGraphics();
System.Drawing.Graphics g1 = c.CreateGraphics();
Then, with the resulting graphics object, I try to create a new bitmap.
Bitmap MyImage = new Bitmap(w, h, g1);
The thing is, this bitmap is blank, unless I paste back in that BitBlt
code. I can't figure out how to get a new bitmap from a graphics object,
without BitBlt().
Sebastien - Using 2.0 isn't an option, unfortunately.
Is there any alternative from P/Invoking in this case?
Thanks for all the help!

Re: [Mono-list] screen capturing in mono
I'm not too sure how to get a Bitmap object from a graphics object. From
all I've read, I just hear that you have to deal with device contexts. I'm
not too familiar with it, but BitBlt seems to be the way to do that. What
would I need to do to get that bitmap created with what appears in the
control using 100% .NET so it can run in mono? Here's a snippet of code.
[System.Runtime.InteropServices.DllImportAttribute("gdi32.dll")]
private static extern bool BitBlt(
IntPtr hdcDest, // handle to destination DC
int nXDest, // x-coord of destination upper-left corner
int nYDest, // y-coord of destination upper-left corner
int nWidth, // width of destination rectangle
int nHeight, // height of destination rectangle
IntPtr hdcSrc, // handle to source DC
int nXSrc, // x-coordinate of source upper-left corner
int nYSrc, // y-coordinate of source upper-left corner
System.Int32 dwRop // raster operation code
);
public static Bitmap PerformCapture(Control c, int maxWidth, int
maxHeight)
{
try
{
int w = c.ClientRectangle.Width;
int h = c.ClientRectangle.Height;
w = System.Math.Min(w, maxWidth);
h = System.Math.Min(w, maxHeight);
System.Drawing.Graphics g1 = c.CreateGraphics
();//this.CreateGraphics();
Bitmap MyImage = new Bitmap(w, h, g1);
System.Drawing.Graphics g2 =
System.Drawing.Graphics.FromImage(MyImage);
IntPtr dc1 = g1.GetHdc();
IntPtr dc2 = g2.GetHdc();
BitBlt(dc2, 0, 0, w, h, dc1, 0, 0, 13369376);
g1.ReleaseHdc(dc1);
g2.ReleaseHdc(dc2);
//Separate dialog to display the image. If I comment out the BitBlt code,
it just appears blank.
Library.Windows.Dialogs.ScreenCaptureDlg dlg = new
Library.Windows.Dialogs.ScreenCaptureDlg(MyImage);
dlg.ShowDialog();
return MyImage;
}
catch(Exception error)
{
//our exception handling library.
Library.Common.ErrMsg.Err( error );
throw error;
}
}

[Mono-list] screen capturing in mono
Hi all, Is there a good way to capture screens or something similar in mono? In our .NET application, we have custom controls, and we basically create a graphics object from it, make a new bitmap, then do a bitblt to get it into the bitmap. This requires a P/Invoke into gdi32.dll, which obviously blows up in mono. Is there a good way to do this using mono? Some other library maybe? I've tried installing wine and using the gdi32.dll.so that comes with it, but I don't know if I'm using it correctly or not. It can find the library, but it gives a SIGSEGV while trying to execute the bitblt operation. Seemed like kind of a hack, and I didn't really expect it to work... Do I need other libraries along with the gdi32.dll.so ? Any advice is appreciated. Thanks.

I don't see why it should be necessary to write one project (one set of classes compiling to a single assembly) in several languages. If you want to extend a class, you create a project referencing the assembly where the class resides in, and extend it, without thought to which language the to-be-extended-class was written in. There's no reason for rewriting the original code to change the language, of course, since the key word is extend (in a new assembly), not rewrite. Since it is possible to split the same namespace through more than one assembly, you need not add classes to a VB.NET project to add more functionality to that namespace if what you really want is to program in C#; you just create a new assembly on the namespace and add what you need to it. If you need to add features to a class, you can inherit from it, or if it's un-inheritable you can always write a wrapper. There's so many different ways to make things work without having to mix languages within one assembly, I really don't see the point. Maybe I'm missing something? :p shana ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

Re: [Mono-list] Interop problem: ** ERROR **: Type System.MarshalByRefObject which is passed to unmanaged code must have a StructLayout attribute
Robert,
Thanks. So it is a "bug" (or at least something that could be improved
upon) in the MS framework, then. But indeed, the basic problem is this:
I need to set some callbacks from unmanaged code. The callback should
contain a stream (or a reference to it) as a parameter.
Is there any way this can be achieved (I heard about "pinning", but is
that something that I can use here)? Another solution would be to use a
dictionary in managed memory and use the key as the parameter on the
callback funcion, but then again that seems like some overkill to me.
Any ideas?
Frederik.

It's not necessarily true that a project needs to be within a single
language. That's an IDE limitation, not necessarily a compiler
limitation.
If all of your compilers support -target:module (which creates
a .netmodule file), you could compile different parts of the assembly in
different languages, then create the final assembly by "merging" the
different .netmodule files by providing -addmodule:filename.
(This of course requires that the compiler support -target:module, and
you can't mix languages within a single class, but this does allow
intermixing languages within an assembly.)
This mixing can only be done a class at a time, so you can't write part
of a class in C# and another part in VB.NET, but you can use inheritance
for similar functionality, i.e. write the base type in C# and the
derived type in VB.NET.
If you wanted to get _really_ tricky, you could mark to-be-merged types
with an attribute -- [WriteType("MergedType")] class CSharpMergedType
{...}, and a VB.NET VbMergedType -- and then write a Cecil program which
will take the two separate assemblies/.netmodule files, look for the
[WriteType] attribute, and merge all types with the specified attribute
into a new type.
(Why you'd want to work that hard is another matter, but it _could_ be
done...)

No. Partial classes are a compiler feature, not a CIL feature. The
compiler merges all "partial" classes into a single CIL type.

This can already be done, though if you use an IDE this is done in
separate assemblies -- a VB.NET programmer writing assembly A.dll can
extend (inherit from) a C# class in assembly B.dll.
(Which is how ASP.NET works -- most of the class library is C#, while
ASP.NET can use VB.NET, Chrome, C#, Nemerle... any language with a
CodeDom provider.)

Re: [Mono-list] Mixed programming languages
I've always felt slightly robbed when its said that a project has to be all in one language in .NET of all environments having mixed and matched languages in projects before - when we had .o in the build path. Would it not be possible (with partial classes?) to actually have a project or a library built using different languages. They all compile to the same underlying code and certain languages make certain assumptions but there is nothing theoretically impossible in the idea of mixing languages. Granted it might impose further requirements in the code but to have a VB.NET programmer extend something written in C# without having to convert the code could be a massive plus for mono. I say this as someone who had to learn VB.NET when I was already fluent in C# and now stutter in both languages.. ___ New Yahoo! Mail is the ultimate force in competitive emailing.
