Re: [Mono-list] Reliable OS identification on Mono
Hi. You can use a condition statement like this. *if(System.Environment.OSVersion.Platform == PlatformID.Unix) **Here is the link to the Mono API:* http://www.go-mono.com/docs/index.aspx?link=T%3aSystem.OperatingSystem%2f* However, I can't find a way to check if its in MAC.

My application needs to access files of some external application (also multiplatform) and those files are located in different places depending on OS. On Windows it is under ApplicationData, on Linux under /home/user/app and on MacOS... I don't know ;) Never installed it.

[Mono-list] Mono Sqlite Question
Hello guys,
I found this code at http://www.mono-project.com/SQL_Lite
I want to ask why it is important to assign null to the Sqlite
objects used in the main function.
Since the function will exit and the local variables used will be
deallocated,
Is it really important to assign *null *to those variables?
Is there a specific behaviour of Mono Sqlite that I should know about?
Thanks in advance,
Marc Glenn
*Please see code below:
* using System;
using System.Data;
using Mono.Data.SqliteClient;
public class Test
{
public static void Main(string[] args)
{
string connectionString = URI=file:SqliteTest.db;
IDbConnection dbcon;
dbcon = (IDbConnection) new SqliteConnection(connectionString);
dbcon.Open();
IDbCommand dbcmd = dbcon.CreateCommand();
// requires a table to be created named employee
// with columns firstname and lastname
// such as,
//CREATE TABLE employee (
// firstname varchar(32),
// lastname varchar(32));
string sql =
SELECT firstname, lastname +
FROM employee;
dbcmd.CommandText = sql;
IDataReader reader = dbcmd.ExecuteReader();
while(reader.Read()) {
string FirstName = reader.GetString (0);
string LastName = reader.GetString (1);
Console.WriteLine(Name: +
FirstName + + LastName);
}
*// clean up*
reader.Close();
*reader = null;*
dbcmd.Dispose();
*dbcmd = null;*
dbcon.Close();
*dbcon = null;*
}
}

Ok. Thank you very much for the response. :) Chris Howie wrote: On Fri, Aug 15, 2008 at 2:04 AM, Marc Glenn [EMAIL PROTECTED] wrote: I want to ask why it is important to assign null to the Sqlite objects used in the main function.

Is there a specific behaviour of Mono Sqlite that I should know about? Those lines will do pretty much nothing, semantically speaking. Usually when you dispose or close something in general it's a good idea to assign null to it, but usually that's more in the case of object fields when that object may still exist for a while. This allows the GC to reclaim those objects if the object that was holding references isn't eligible for GC yet. In this case it's not necessary or useful. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

[Mono-list] Cannot Print Landscape
Hello guys,
I am using System.Drawing.Printing namespace to print a string in a
*landscape* page orientation.
I set the property *PrintDocument.DefaultPageSettings.Landscape* =
true so the PrintDocument
would print in *landscape*.
I compiled it in Windows using SharpDevelop's .NET C# Compiler and
it prints in landscape fine.
But when I used *gmcs* to compile, it still prints in portrait
orientation.
I am using *mono1.2.5.1 *in *win32. *I also compiled it in
*mono1.9(Preview3)* but the same problem
still occurs.
Is this a bug of mono or am I just doing something wrong?
I attached my source code. Please help me.

[Mono-list] Need help in compilation
Hello folks,
I installed the mono-1.2.5.1 installer for windows xp. It has
gtk-sharp 2.10 and gnome 2.16 included.
I also found *PrintSample.cs* in the samples directory. This
PrintSample.cs uses the Gnome namespace to print.
I am having problems on how to compile it using mono on windows. I
don't know what library to include so the Gnome namespace can be
accessible. Butwhen I compile it on mono(linux), it runs fine.
Also, when I tried copying the PrintSample.exe which is produced by
a mono(linux) compilation. It won't run on my mono(windows). It outputs
a System.DllNotFoundException.
Attached is the *PrintSample.cs *file.
Does anyone know how to compile it correctly on a windows machine?
Desperate already,

Re: [Mono-list] [Gtk-sharp-list] Need help in compilation
Thanks for the reply. :) Actually, I tried using the example in the GtkDemo first. But when I try to use the PrintOperationAction.PrintDialog property, I can't seem to find a way to make the dialog modal with the parent because I don't have a reference to the actual dialog widget. I also can't find documentations for the PrintContext or PrintOperation class. Do you know any documentation for these classes?

[Mono-list] Problem with GtkWindow.Deletable

I am having problems when I try to remove the close button of a

I tried setting the property GtkWindow.Deletable to *false* and it

the window except from the *title bar*.
Attached with this message is a sample code of the problem that I
experienced.
I compiled the code in a windows environment using
*gmcs -pkg:glade-sharp-2.0 DeletableTester.cs
* Is this a problem with Mono?

[Mono-list] Need Help: Mono under Windows-problems in using events
Hello guys,
I tried compiling a csharp code that uses gtk# and event handlers
under Mono.
// 04-gtk/01-basics
using System;
using Gtk;
class MainClass {
public static void Main (string[] args)
{
Application.Init ();
Window w = new Window (Gtk# Basics);
Button b = new Button (Hit me);
w.DeleteEvent += new DeleteEventHandler (Window_Delete);
b.Clicked += new EventHandler (Button_Clicked);
// initialize the GUI
w.Add (b);
w.SetDefaultSize (200, 100);
w.ShowAll ();
Application.Run ();
}
static void Window_Delete (object o,
DeleteEventArgs args)
{
Application.Quit ();
args.RetVal = true;
}
static void Button_Clicked (object o, EventArgs
args)
{
System.Console.WriteLine (Hello, World!);
}
}
The program prints a Hello World on the Console after clicking the
button Hit Me.
I executed it under Fedora Core 6 using the latest version of Mono
compiler and it operates perfectly.
But when I try to run it under Mono-Windows(latest version) and
click the button Hit Me, the program crashes.
I have tried to comment out these lines
w.DeleteEvent += new DeleteEventHandler (Window_Delete);
b.Clicked += new EventHandler (Button_Clicked);
and when I click the button Hit Me, the program does not crash
anymore.
Does this mean that Mono have problems with csharp events or I just
have a wrong configuration of my Mono-Runtime..
Need help..
Thanks in advance
