| Problem With Mailto Start Process by:Wayne Wengert | |
| I am using a Sub (see below) to call the default mail application and pass a list of email addresses and a subject. Most of the time this works perfectly but occasionally I get an error ("System NullReferenceException: Object reference not set to an instance of an object"). From what I've been able to determine, this occurs when there is a username (left of the @) with a period such as joe.smith@somesite.com). Has anyone seen this type of problem and have suggestions on how to resolve it? ================ Code ===================== Public Sub StartDefaultMail( _ ByVal [To] As String, _ Optional ByVal Subject As String = "" _ ) Try Dim psi As New ProcessStartInfo psi.UseShellExecute = True psi.FileName = _ Process.Start(psi) Catch ex As Exception MsgBox("Exception: " & ex.ToString, MsgBoxStyle.Information, "Error") Throw _ New Exception( _ ex _ ) End Try End Sub | |

Is it possible to get the callstack for the exception? -- Herfried K. Wagner [MVP] | |

| Herfried; Is this what you need? at Microsoft.Win32.NativeMethods.ShellExecuteEx(ShellExeuteInfo info) at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startinfo) at System.Diagnostic.Process.Start() at System.Diagnostics.Process.Start(ProcessStartInfo startInfo) at OfficeApp.Module1.StartDefaultNail(String To, String Subject) in c:\2005 myProjects\TestApp2\Module1.vb:line 100 Wayne | |

Yes, but I still don't have an idea. 2005 -- are you using VS 2005 (CTP?)? -- Herfried K. Wagner [MVP] | |
