It is typically unnecessary to call the Stop method, because the code stops executing when the process exits.

I wrapped it for symmetry. I don't suppose it has much use.

zip library for dotnet from http://dotnetzip.codeplex.com/
the script is working ok, but unfortunatley problemes are
1)
it's not compatible with COM_L.
When calling CLR_createobject, com_l throws an error message.
2)
And I notice you made an explicit statment that the "static" method can't be called, which I don't know at all.
but from what i have tested so far, I guess that it means like system.Net.Dns class's gethostname method
'cause dns class has no contruction method so i couldn't create object for it and therefore couldn't call Gethostname method.
or is it possible to call dns.gethostname method with CLR lib?
3)
and finally could it be possible to make dot syntax possible as in Autohotkey_L and Com_L
possible or not, thanks for the script and Autohotkey_L.
Com_L and autohotkey_L combination is really fantastic.

COM_L has been updated to fix this issue.it's not compatible with COM_L.
I'm going to assume you mean that CLR.ahk was throwing an error mesage about number of parameters passed to COM_CreateObject. If that's not correct, please give more detail.When calling CLR_createobject, com_l throws an error message.
Static methods can't be called with COM_Invoke because it requires an object to invoke. Static methods can be called, and in fact are called internally by CLR.ahk. It is difficult enough that I would recommend using embedded C# or VB in your scripts (as in the MessageBox.Show example).And I notice you made an explicit statment that the "static" method can't be called,
You may use COM_Enwrap to wrap any pointer which works with COM_Invoke, including those returned by CLR_CreateObject.and finally could it be possible to make dot syntax possible as in Autohotkey_L and Com_L
I tested briefly with the following (and updated COM_L):
CLR_Start() lib := CLR_LoadLibrary("mscorlib") obj := COM_Enwrap(CLR_CreateObject(lib,"System.Object")) COM_Release(lib) MsgBox % obj.ToString()A "select few" types have ProgID's (keys in HKEY_CLASSES_ROOT), so can be simply instantiated with COM_CreateObject:
obj := COM_CreateObject("System.Collections.ArrayList") MsgBox % obj.ToString()

COM_L has been updated to fix this issue.
At first I couldn't decide whether it is appropritate to ask here or COM Thread.
But since I had some other questions about CLR, I came here. Thanks for the request.

OK, I tried that. It's working flawlessly though it's a bit tricky for me.

I saw that function name before but until now i didn't know what the heck it is for. :lol:
Now I get it!
Some silly requests and sweet, detailed guides from the master!
Thanks, Lexikos

How do I enumerate a System.Object[]? I have tried this (using COM_L):
Loop, % array.Length myArray%A_Index% := array.GetValue(A_Index-1)But it doesn't work...

CLR_CompileAssembly wasn't working in COM_L/U, so I've uploaded a new version of CLR with the following changes:
[*:1y5uk178]AutoHotkey_L or AutoHotkeyU required. (However, the old version is still available.)
[*:1y5uk178]CLR_LoadLibrary, CLR_CreateObject, and CLR_CompileC#/VB return a COM wrapper object.
[*:1y5uk178]It should not be necessary to call CLR_Start explicitly.Note that in simple cases, Assembly.CreateInstance(TypeName) can be used in place of CLR_CreateObject:

Hi Lexikos and all!
Im fairly new to C# and really want to learn it
(and someday write some dll to use with ahk)
Just for fun, a few days ago i followed a tutorial on how to create a C# DLL. I compiled it with C#2008Express and tried to DllCall it. But it didnt work(returned Errorlevel=-4 Function not found). Even the disasm didnt show any exported functions. I considered that the dll was to use with only C# as a class lib(i tried it with c# and obviously it worked).
So With this CLR for Ahk, will I be able to call functions from C# dlls?
edit: I cant call mscorlib.dll

Post code if you're having difficulty. It sounds like you're still trying to use DllCall, in which case you wouldn't actually be using this script.edit: I cant call mscorlib.dll
Typically you'll need to load an assembly (CLR_LoadLibrary), create an object from it (CLR_CreateObject), then invoke the object (COM_Invoke). Make sure you're using the appropriate version of CLR.ahk for your version of AutoHotkey. That is, CLR for standard AHK or CLR_L for AutoHotkey_L (allows "dot" syntax and automatic cleanup). For instance:
; CLR or CLR_L CLR_Start() ; one-time init mscorlib := CLR_LoadLibrary("mscorlib") cookie := CLR_CreateObject(mscorlib, "System.Object") MsgBox % COM_Invoke(cookie, "ToString") COM_Release(cookie)
; CLR_L only mscorlib := CLR_LoadLibrary("mscorlib") cookie := CLR_CreateObject(mscorlib, "System.Object") MsgBox % cookie.ToString() cookie := "" ; optional in this case

Thx for the reply,
but how can i use Math.Tan method (http://msdn.microsof...m.math.tan.aspx)

CLR_CreateObject is only for instantiating a class. Static methods like Math.Tan are difficult to call via COM as it requires...
[*:2252zeql]getting an instance of the Type object representing the type which contains the method,
[*:2252zeql]initializing a SAFEARRAY of VARIANTs containing parameters,
[*:2252zeql]calling the appropriate overload of Type.InvokeMember via a complicated DllCall, and
[*:2252zeql]interpreting the result VARIANT as necessary.For instance, this is a slightly modified (for readability) extract from CLR.ahk:

Assembly.LoadFrom(sLibrary)It's generally easier to use C#.

SetFormat, FloatFast, 0.14 ; for results closer to the above MsgBox % Tan(1.0) MsgBox % Tan(0.5)

I dont really wanna create Assemblies to use with C#
instead the dll should have exported functions
in Borland Delphi, its much easier
i downloaded Delphi7 and built my first dll using an example and i can use it in ahk with DLLCALL

I wasn't suggesting you do. Any assembly you create with CLR.ahk must be written in C# or VB.Net anyway. My example shows how to use C# in AHK to make static methods more accessible to AHK.I dont really wanna create Assemblies to use with C#
Exporting functions in a way that allows them to be called by DllCall requires a bit of work and does not involve CLR.ahk. If you want to use CLR-based objects (i.e. not just flat functions) in AHK, use CLR.ahk but avoid static methods.instead the dll should have exported functions
