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.F ile.Exists(file Name))
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.Fi leIOPermission, mscorlib,Versio n=2.0.0.0
Culture=neutral PublickKeyToken =b77a5c561934e0 89 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.

* the save procedure:

*public Boolean Save(String fileName)

*Boolean result = false;
*try *{

* *if(!System.IO. File.Exists(fil eName))
* * *System.IO.File .Create(fileNam e);
* *MessageBox.Sho w("22222");
*}
*catch (Exception e)
*{
*MessageBox.Sho w(e.Message);
*result = false;
*}
*return result;
*}

Object1.Save("c :\\aaa.txt");

How did you do that?
