From: mmmobahser ----------------------- Posted by a user from .NET 247 (http://www.dotnet247.com/) <Id>7N75u9Y/hEyqfiD4tgUBiQ==</Id> Just guessing here, but is the file marked as read-only or is it already on
CD when you attempt to open it? If so, you should specify that you only need read access. e.g.: yourStream = new FileStream(filePath, FileMode.Open, FileAccess.Read) BTW, disabling CAS won't help you here since the exception almost certainly has nothing to do with either CAS or the .NET Framework. "may mana via .NET 247" <anonym***@dotnet247.com> wrote in message I get some marvelous error from my c# program again & again, i guess it is a news:epaTj20IFHA.3696@tk2msftngp13.phx.gbl... security exception error, so i disable security with caspol -s off, give it full trust, copy it to hard drive, copy it to cd drive, sign it with public/private key, in all these cases i got the same exception, i use framework 1.1.4322. and just want to read the file, not write to it, also i am admin of my computer! and it is in the same directory. why i got this error? below you can see the exception text. access to the path "g:\saving document6.cad" is denied See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.UnauthorizedAccessException: Access to the path "G:\saving document6.cad" is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String str) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean useAsync, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode) at wordtraining.main.lessonup() at wordtraining.main.lbxLesson_DoubleClick(Object sender, EventArgs e) at System.Windows.Forms.Control.OnDoubleClick(EventArgs e) at System.Windows.Forms.ListBox.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) ************** Loaded Assemblies ************** mscorlib Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/winnt/microsoft.net/framework/v1.1.4322/mscorlib.dll ---------------------------------------- wordtraining Assembly Version: 1.0.1249.40111 Win32 Version: 1.0.1249.40111 CodeBase: file:///C:/Program%20Files/Rayan/wordtraining/wordtraining.exe ---------------------------------------- System.Windows.Forms Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/winnt/assembly/gac/system.windows.forms/1.0.5000.0__b77a5c561934e089/system.windows.forms.dll ---------------------------------------- System Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/winnt/assembly/gac/system/1.0.5000.0__b77a5c561934e089/system.dll ---------------------------------------- System.Management Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/winnt/assembly/gac/system.management/1.0.5000.0__b03f5f7f11d50a3a/system.management.dll ---------------------------------------- System.Drawing Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/winnt/assembly/gac/system.drawing/1.0.5000.0__b03f5f7f11d50a3a/system.drawing.dll ---------------------------------------- AxMP3PLib Assembly Version: 1.0.0.0 Win32 Version: 1.0.0.0 CodeBase: file:///C:/Program%20Files/Rayan/wordtraining/AxMP3PLib.DLL ---------------------------------------- MP3PLib Assembly Version: 1.0.0.0 Win32 Version: 1.0.0.0 CodeBase: file:///C:/Program%20Files/Rayan/wordtraining/MP3PLib.DLL ---------------------------------------- Accessibility Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/winnt/assembly/gac/accessibility/1.0.5000.0__b03f5f7f11d50a3a/accessibility.dll ---------------------------------------- ************** JIT Debugging ************** To enable just in time (JIT) debugging, the config file for this application or machine (machine.config) must have the jitDebugging value set in the system.windows.forms section.
