SecurityException

Hi,

I got the security exception in underlined code:

string sAppProgID = "Excel.Application";

object oExcel = null;

try

{

oExcel = Marshal.GetActiveObject(sAppProgID);

}

catch(Exception ex)

{

MessageBox.Show(ex.StackTrace);

try

{

Type tExcelObj = Type.GetTypeFromProgID(sAppProgID);

oExcel = Activator.CreateInstance(tExcelObj);

}

catch(Exception ex2)

{

MessageBox.Show(ex2.StackTrace);

return;

}

Why is it happened and how can I solve it

Thank's
Alexei

Hi,

The type of oExcel object is Object and I can't take the exist object of Excel or create new object of Excel. It tells me security exception. If I add it to security permissions I get error with no reference to object Excel.Application.

Thank's

Rather than just displaying the StackTrace, try putting more of the SecurityException in your message box with MessageBox.Show (ex). I don't know all the properties SecurityException.ToString() includes in the message but it should provide more details on the security error that occurred. For even more data you could either show all the SecurityException properties or more quickly just examine ex with the debugger.

Your code needs the permission to call unmanaged code.
