Here you re using a User Control event to count the number of controls whose values have changed All of the TextBoxes on the User Control raise this event when their TextChanged event fires Here is the code from the User Control: public partial class RenderTextBoxes : SystemWebUIUserControl { public event SystemEventHandler FieldChanged; override protected void OnInit(EventArgs e) { for (int i = 0; i < 10; i++) { TextBox t = new TextBox(); thisControlsAdd(t); tTextChanged += new EventHandler(t_TextChanged); } } baseOnInit(e); } } private void t_TextChanged(object sender, EventArgs e) { if (FieldChanged != null) { FieldChanged(this, new EventArgs()); } } } In any given execution of the event trap at the Page level, you can t be sure that it s the last time the event will fire.

thread) associated with it, whereas in shared server mode, a pool of processes (or threads) is shared by all physical connections. Dedicated server is the more commonly used option. Please see the Oracle Database Concepts Guide (10g Release 1) document for more details.

fs Note that you use the keyfile switch to indicate to the compiler that the output should be signed using the specified key pair Now you can add the assembly to the GAC (note that under Windows Vista the shell used should run with administrator privileges): C:\ > gacutil /i hwfsdll Microsoft (R) NET Global Assembly Cache Utility Version 205072742 Copyright (c) Microsoft Corporation All rights reserved Assembly successfully added to the cache.

So you wait until the PreRender event fires to act on the data you re creating as you trap events from the User Control You could do this work from the FieldChanged event trap of the User Control (relying on the fact that it would be correct the last time it fired), but this is less efficient and won t work for all types of processing Imagine if you were updating the database or doing a redirect as a result of the work being done on the User Control Clearly the PreRender event is a better option As an improvement over version 1x, even if the Page code needs to respond to work done in the User Control s PreRender event trap, you have the page-level PreRenderComplete event that fires after all PreRender events fire for all controls in the tree.

Now you can use the regasm.exe tool to register the hwfs.dll assembly as a COM component: C:\ > regasm hwfs.dll Microsoft (R) .NET Framework Assembly Registration Utility 2.0.50727.312 Copyright (C) Microsoft Corporation 1998-2004. All rights reserved. Types registered successfully Now you have to write the script using the Jscript language to test the component; the script will use the CreateObject method to create an instance of the F# object type, with the CCW generated by the CLR taking care of all the interoperability issues. But what is the ProgID of the COM component You use regasm.exe with the /regfile switch to generate a registry file containing the keys corresponding to the registration of the COM component instead of performing it. The generated registry file contains the following component registration (we ve included only the most relevant entries): [HKEY_CLASSES_ROOT\Hwfs+FSCOMComponent] @="Hwfs+FSCOMComponent" [HKEY_CLASSES_ROOT\Hwfs+FSCOMComponent\CLSID] @="{41BFA014-8389-3855-BD34-81D8933045BF}" [HKEY_CLASSES_ROOT\CLSID\{41BFA014-8389-3855-BD34-81D8933045BF}] @="Hwfs+FSCOMComponent" [HKEY_CLASSES_ROOT\CLSID\{41BFA014-8389-3855-BD34-81D8933045BF}\InprocServer32] @="mscoree.dll" "ThreadingModel"="Both" "Class"="Hwfs+FSCOMComponent" "Assembly"="hwfs, Version=0.0.0.0, Culture=neutral, PublicKeyToken=97db6c0b1207bed4" "RuntimeVersion"="v2.0.50727" The InprocServer32 subkey indicates that the COM component is implemented by mscoree.dll, which is the CLR, and the additional attributes indicate the assembly that should be run by the runtime. Note that the ProgID and the class name of the component is Hwfs+FSCOMComponent, which is partly derived from the namespace Hwfs generated by the F# compiler. You can now try to write the following script in the hwfs.js file: o = WScript.CreateObject("Hwfs+FSCOMComponent"); WScript.Echo(o.HelloWorld()); If you execute the script (here using the command-based host cscript), you obtain the expected output:
