Using C# to create ActiveX

[JUN]

Hi all,

I use c# to create ActiveX control, and works under IE browser.

Now, i add a "Save" procedure for this ActiveX,but in Client
calling ,it not works.

the save procedure:

public Boolean Save(String fileName)
{
Boolean result = false;
try {
MessageBox.Show("11111");
if(!System.IO.File.Exists(fileName))
System.IO.File.Create(fileName);
MessageBox.Show("22222");
}
catch (Exception e)
{
MessageBox.Show(e.Message);
result = false;
}
return result;
}

the client (javascript code)
Object1.Save("c:\\aaa.txt");

The error message:

System.Security.Permissions.FileIOPermission,mscor lib,Version=2.0.0.0
Culture=neutral PublickKeyToken=b77a5c561934e089 Failed.

I have set this Assembly to FullTrust. but still not works.

First of all, it's not ActiveX; it's a hosted Windows Forms control.

* Now, i add a "Save" procedure for this ActiveX,but in Client

* the save procedure:

*public Boolean Save(String fileName)

How did you do that?
