I had to study the examples in the SDK QuickStart (plus others I found online) quite a bit before I got my own custom control working just the way I wanted. I changed your code slightly in headers and declaration, and the event is now triggered; hope this at least helps get you started. Check out esp. info on implementing the INamingContainer interface and EnsureChildControls.
Regards,

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace TestCustUC
{
//[ToolboxData("<{0}:WebCustomControl1 runat=server>")]
public class WebCustomControl1 : Control, INamingContainer
{
private Button butOK;
public event EventHandler Click;
protected override void CreateChildControls()
{
butOK = new Button();
butOK.Text = "OK";
butOK.Width = Unit.Pixel(50);
Controls.Add(butOK);
// Add handler for the OK button click postback event.
butOK.Click += new EventHandler(this.OnButOK_Click);
}
protected /*virtual*/ void OnButOK_Click(object sender, EventArgs e)
{
if (Click != null)
{
Click(this, e);
}
}
}
}

epatton -- Thanks for taking the time to dig into my code and suggest changes and resources for more information!
I played with the code as well and got it to work following a different avenue. It appears that if you attribute the control class for design time support ([DefaultProperty("Text"),ToolboxData...), then you should follow through and implement, for example, the 'Text' property, using the call to 'EnsureChildControls'.
Sounds OK, huh? But the project still didn't run correctly!
This will sound like a bunch of hocus pocus, but the next thing i did was to re-arrange the Page and Register directives on the .aspx page that used the control, F5 and then everything ran perfectly!
I believe this forced VS to rebuild its in memory representation of the project, rewiring the project correctly and allowing it to run.
Anyway, that's my theory....
Thanks again for your help.

But i want to access the function of child form

thanks

when you open a new window using window.open(), you end up naming the window in the second argument.
window.open("bob.html", "bobWin", "width=500, height=500") for example creates a new window called bobWin. if you use that instead of "window", you should be able to point to anything there.

I tried to access the frames in an HTML page hosted by CWebBrowser2 control. Each time, I can query valid IOleContainer interface. However. When use EnumObjects function of this interface, an exception was thrown. Does anybody know what kind exception was thrown, what cause this problem?
I followed the instructions published in Microsoft web (How to get the WebBrowser object model of an HTML frame http://support.microsoft.com/default.aspx?id=196340) here are the codes:

Hi all, i am involved in writing an application at the moment that will require IIS to be installed to run. Is there a way that i can check to see if IIS has already been installed when i install my application? And if it has not already been installed i need to install it, although i think i can manage that bit 
Cheers

Hi,
does anyone know how macromedia does the silent install of the flash player? do i need wise to automatically install some components? or can i use msi...if so how do i do it?
thanks

i know that other tools have a "/silent" option, where you can execute them with the silent commandline flag. i would presume that msi would have the same or similar...

Even though it is not defined on this page :p, the .msi install option you want is "/q". I'm sure there is a similar list of .msi install option flags somewhere on Microsoft's site...

the short answer is: you can't.
the long answer is: you can get the user to download the file.

Thanks for the reply.
Actually I am searching for a solution other than download or saveAs method.
That means the work should be done without user's knowledge.
Thanks

like i said before: you can't. the webserver doesn't even know who or what the client machine is. the only way you can transfer files to the client machine is via active download. the client *has* to request the file, the server cannot just send it.

Imagine surfing to a website, and without your knowledge they could place a file on your hard-drive (*). I think you can see why this is not permitted.
(*) There have been security flaws in IE that allow exactly this, but they are usually shut by the next security patch.

First:
When I use a router with internal IPs and I use a high anonimity HTTP proxy directly in the browser, the JavaScript see my real IP, it doesn`t see the Local IP, when I use a socksifier with a socks proxy in it like SocksCap and I socksifity the Browser through SocksCap, the JavaScript see as Local IP the internal IP adress of the computer (router ip adress) also Java can`t give to the server the truly real ip ! Why is this difference ? also with HTTP proxy directly in IExplorer, Java see the truly real ip alltrough I use a router, and Why with a socksifier the result is the best also...Java is not capable to see the truly real ip ?
Twice:
I have a problemm also when I use a anonimity HTTP proxy in the Internet explorer but I have Java enabled, the Java script test see my real IP directly from the network card settings, I can`t change the card ip because...the net doesn`t work then, I know that with a router can I use a internal IP and so Java see only this IP as Local IP but I wish that I don`t use the router also I want a program which can spoof the JavaScript results also....for example The Java must give to the test server a fake real ip as truly network card ip (Local IP). I wish put in the program the spoofed ip for example...1.1.1.1 and the JavaScript give to the server "Real IP: 1.1.1.1 (Local IP)" Can someone help me ?

i would like to know what is MFC?
|
|
|
|

The Microsoft Foundation Classes (MFC) are a set of classes which wrap the native Windows API and supposedly make it simpler to program. Support for MFC ended with Visual C++ 6, though there is a huge amount of existing software out there using it.
Since this is a web forum, and your previous post mentioned a web project, I assume that you're trying to create a web application. In that case, I'd highly recommend that you not waste your time on MFC, but move directly into C# or C++ development using Visual Studio .Net 2003. VS.Net 2003 and the CLR make it wonderfully easy to create web-based applications. If for some reason you're constrained to using MFC, check out the excellent collection of articles here at Code Project to help you get started. You might also spend some time at msdn.microsoft.com [^], but Microsoft has been deleting content related to MFC faster than I can click a link.

i would like to make a library project
in my company,and i would like to make
it a web application,
and in the same time, i would like to use
oracle database
what is the optimal way for this
thank for all

Well, it is difficult to answer such a question without knowing more specifics. However, I will try. If you are running Microsoft Windows, I recommend that you get a copy of Visual Studio.NET and then read through a tutorial on creating web applications that connect to a database to create dynamic web pages.
If you could provide more information, such as your development machine's operating system and your webserver's operating system, we could give you better answers.
Good luck!

Yes, I recommend Visual Studio.NET as the tool to use to build your library web application project. I find Visual Studio.NET to be a good tool for software development.
You might also be interested the free and open source development tool SharpDevelop. It can use .NET as well, though it is not as powerful a tool as VS.NET.
It would help me to help you if you could answer the following questions:
Do you already know how to program software applications?
What programming languages do you know?
Have you developed any web applications?
Have you worked with databases?
When you say you want to develop a library application, do you mean a media library consisting of books, magazines, CDs, etc?
You should also check out the following links, as they point to sites that offer free and open source software applications for media libraries:
http://www.koha.org
http://www.oss4lib.org
Let me know if you have any more questions.

Great, this is the information I needed to help you!
I recommend strongly that you get a copy of Visual Studio.NET and learn about VB.NET and ASP.NET. Since you are already experienced with VB6, you will find this to be not only easy but a great source of pleasure.
Next, you will need to learn a bit about ASP.NET for web application programming, but again this will be straight forward.
ADO.NET is used to connect to databases, but it is so easy you won't need to know much about it.
I also recommend strongly that you purchase a book about using VB.NET and ASP.NET to create web applications. There are many out there. I recommend: http://www.oreilly.com/catalog/progaspdotnet2/
Finally, there are _many_ websites on the WWW that cover these topics. Use Google and look for them.
Here's one that I found that I think you will benefit from:
http://www.microsoft.com/seminar/events/series/msdnaspnetoct.mspx
Start with a simple webpage form that retrieves data from a database in order to learn how it works, then build on that knowledge.
Good luck!
John
