Almost every peace of code in windows programming is processed at runtime
well for this problem. u may save the references (pointers) of the currently
open forms in a hashtable or in any dynamic datastructure(e.g list) and
upon an event (e.g button click ) u just iterate that list and close the
forms by calling the appropriate messagecall.

Here's a link from MSDN that deals with a similar subject. Perhaps it will help.

I am developing a web app that calls on the execution of an external application. The code compiles with no errors, however, the external execution is never implemented.
I am not at all sure what I am doing wrong. I've done the same thing using a windows form and it works. Could it be a security issue? Is it how I'm calling on the external application?
Me, wrong!?! Nah, you just need to change your thinking to make me right.

Is this a WinForms embedded in IE app or an ASP.NET web app? The former you will need to setup the security policy via the .NET framwork configuration (mscorcfg.msc). The latter you will need to give the ASP.NET and the IIS user account execute rights for the process in question.
Hope this helps

i face some problem in passing struct data type in web service style.
i create a web service:
---------------------------------------------------------------------
[WebMethod]
public string HelloWorld(System.Drawing.Color c)
{
if(c == System.Drawing.Color.Red)
return "RED";
return "NOT RED";
}
---------------------------------------------------------------------
i face no problem in generating web service proxy for the above code
by using wsdl tool.
i write a dummy test code:
---------------------------------------------------------------------
Service1 s = new Service1();
Console.WriteLine(s.HelloWorld(System.Drawing.Color.Red));
---------------------------------------------------------------------
i get the compilation error 
dummy.cs(8,35): error CS1502: The best overloaded method match for
'Service1.HelloWorld(Color)' has some invalid arguments
dummy.cs(8,48): error CS1503: Argument '1': cannot convert from
'System.Drawing.Color' to 'Color'
any suggestion in solving this problem? thank you.
regards

Sounds like you have defined another Color type or it theres a version mismatch...

ERROR : "The type or namespace name 'Net' does not exist in the class or namespace 'System' (are you missing an assembly reference?)"
I get this error on 'using System.Net;' and I'm obviously not understanding something quite important. I've been doing console-apps in C# for a while now and I have never bumped into this assembly-stuff before. I've searched the net and MSDN without figuring this out. Please help me 
Edit: I figured it out at last!! (At least I think so)

Can anyone help me?

Okay,
I've got two apps.
1) in C++ using WinInet.
2) in C# using WebRequest
When requesting the same URL in each I get a diffenent page of HTML returned.
The C++ version is fine, but the C# version is not.
It seems to stem from the fact that the site is saying its and unsuported browser from the C# app!!!! I get the same undisired result in the browser Opera.
So, does anyone know what provides the same functionality as WinInet from .NET?
I was thinking maybe I should not be using Webrequest, but Webclient, but I get the same result. I'm guessing that something in the header of the .NET implementation is not there, or disimmilar to Internet Explorer.

Use System.Net.HttpWebRequest instead and set your UserAgent string to match your PC's browser.

Thanks. I'll give it a try.
You don't know what IE6's UserAgent string is like to you?
I know its somthing like - Mozilla4.0(compatible, IE6) bla bla bla.
Thanks,
Giles

No still not having it. The CHttpConnection set of classes in MFC work fine for the url, but HttpWebRequest is not working even why I apply the User-Agent to the header.

Here it is:
http://www.gsgdirectory.co.uk/CGI-BIN/GSGDir.exe?SDETAILSPAGE&NUMGSG=124383[^]
The .NET classes return a different page, to IE.
As I said the WinInet library returns the same page as IE. If you want to test it quickly Chris has built page grabber class in this article : http://www.codeproject.com/internet/webgrab.asp[^]
It uses the MFC http classes which I'm right in thinking use WinInet. Also the VB Internet Transfer control correctly pulls down the page.
Thanks,
Giles

This appears to be happening because of a javascript redirect within the HTML. I'm not sure how WinInet or the VB transfer control handles that. Both HttpWebRequest and WebClient gave the same results. Not the one you are looking for though  It could be a frames issue as well.

I don't think its the Java script, as what it redirect to is the same. It could be the frames, but I don't see what its trying to pull out.

I need to enumerate all the files in a folder, but I can't see how to do this in C#.
In C++ I would just use FindFirstFile(), but I can't find any functions that does that in C#, only a sample about interop/marshalling that shpws how to use the FindFirstFile API.
Is it really true that there is'nt any functions/classes to do that in the .NET framework/C#?

Take a look at the System.IO.Directory & DirectoryInfo.
Also there is File and FileInfo.
I think you make use of the members of the xInfo class.
e.g.
DirectoryInfo dir = new DirectoryInfo(Directory.GetCurrentDirectory());
Console.WriteLine(dir.FullName);
foreach(FileInfo f in dir.GetFiles())
{
Console.WriteLine("{0} - {1}", f.Name, f.Length)
}
This seems like a pain, but you get used to it.
For a seriously handy class look at System.IO.Path and its static members. Evrey thing you ever needed for manipulation a file path.
