How to handle the fact that controls have a different size under mono

butterknife — 2013-05-04T06:44:32

Winforms controls seem to be of a different size under mono then they are
under .net, this sometimes results in controls being cut off because they
are wider than the window they are in. Is there an effective approach to
resize the windows or force controls to be the same size as they are under
.net, that people recommend?  I am using Lubuntu with Mono JIT compiler
version 2.10.8.1 (Debian 2.10.8.1-5ubuntu1) and
building using Mono Develop 3.0.3.2 and project originally developed in
VS2010.

Re: Updating GUI from an asynchronous thread

Ian Norton — 2013-04-03T09:59:31

Reading your program, it looks like you only run the gtk main loop when
your child gives you data.

Also, that is gtk, this is the win forms list :-)

Updating GUI from an asynchronous thread

Neil Thackeray — 2013-04-02T19:36:56

I'm having trouble getting the output from a command line program to 
appear in the main window of a form. For simplicity I'm just trying to 
get it to appear in a label for now. When I run the function RunIt 
nothing from stdout of the child process appears in the label, but 
ConsoleWriteline seems to pick it up just fine. When it gets down to the 
while loop it updates the label perfectly fine.

I've also noticed that the form seems to be locked while the child 
process is running. When I was just using BackgroundWorker without 
Application.Invoke the form updated from the child process and the while 
loop, but the update was spotty and the application crashed sporadically.

Any suggestions are appreciated.

Thanks

namespace windowtest
{
public partial class MainWindow: Gtk.Window
{
     public MainWindow (): base (Gtk.WindowType.Toplevel)
     {
          Build ();
     }

     protected void OnDeleteEvent (object sender, DeleteEventArgs a)
     {
         Application.Quit ();
         a.RetVal = true;

Hi
I'm sure there are still some bugs, I can recall pretty high activity 
regarding fixing some WinForm bugs a year ago.
I hope You won't have too much problems.

Reasons for this:

Looks - not great (actually quite ugly), but for testing how code works

Yes. We develop all kinds of apps - enterprise with server side ASP.net

First versions and unit tests are usually written for desktop - Windows 
Forms, just it is easier to debug and develop.
Then with sharing code we hit other platfroms desktop and mobile.

If You need Linux + Windows  [+ Mac] start with WF, but do not expect

Help with Mono uses

Innovative Solutions SL — 2013-03-20T08:51:35

Good morning.

I have some doubts on how to deal with applications that I want to develop.

I need to develop applications for a smart camera (VRMagic, in the
description says it is compatible with MONO. NET) that has Linux (Debian)
and above these applications I want to develop a setup wizard in C # where
the user can set up the camera.

I'm using Visual Studio and would like to use it as IDE if it's possible.

My question is:

How I can do this with MONO?

Can MONO be integrated with Visual Studio or do I have to use Xamarin
Studio?

Can use WinForms with MONO?

I will be grateful if you clarify me what it is the best solution for my
application.

Thank you and best regards,

Roberto.

Incorrect, missing,and duplicate keypress events

xFleury — 2013-03-08T02:14:49

There appears to be a bug in how the OS X implementation of keyboard events
is handled. The bug reveals itself when either multiple keys are pressed in
rapid succession or all at once.

Running my app on Win7 if I hit the keys 'J' 'K' 'L' all at once, I can
always get all three keys (though not in any particular order). But on OS X,
while running Windows Forms applications, I can get 'JJJ' or 'JKK' or 'LLL'.
Nowhere else in OS X is this behavior exhibited (native Cocoa apps, such as
TextEdit, behave identical to Win7).

Source code: (in Visual Studio, create a windows forms project, and edit
Form1's code):

public partial class Form1 : Form
{
    public Form1(){
        InitializeComponent();
        KeyPress += Form1_KeyPress;
        KeyDown += Form1_KeyDown;}
    void Form1_KeyDown(object sender, KeyEventArgs e)
        {Console.WriteLine("KeyDown: " + e.KeyCode.ToString());}
    void Form1_KeyPress(object sender, KeyPressEventArgs e)
        {Console.WriteLine("KeyPress: " + e.KeyChar.ToString());}
}

Re: I can install alone mono and not framework

Paul Johnson — 2013-03-01T15:02:59

Hi,


The archive contains everything and is compressed. When you decompress 
it, everything gets bigger.

Don't get the SDK version, you just need the runtime environment


Not a problem

I can install alone mono and not framework

4 looked for alternative to framework, since when net installed it framework
client, on disc it occupies very much 1GB

and I do not want to fill disc of so many files

I do not understand how a file of 41mb ends up by filling so much the disc
and has to cover several services

pardon for my English I am from Spain

Tab Control Issue on Mac OSX

Nigel Delaney — 2013-01-15T05:48:53

Hello,

 

Thanks to all who have been working on this project!  I had a quick question
I was hoping someone could help me with.    I was hoping to port an
application to the Mac OSX using mono, but sadly appear to have run in to a
problem with controls on hidden tab controls painting themselves on the main
window, even if not in that tab.  I have seen this described (a bit better)
a few places online as filed bug reports:

 

http://lists.ximian.com/pipermail/mono-bugs/2010-December/107562.html

 

http://lists.ximian.com/pipermail/mono-bugs/2010-December/107542.html

 

https://bugzilla.xamarin.com/show_bug.cgi?id=3124

 

Unfortunately,  I don't have regular access to a Mac computer (or any
knowledge of the apple particulars) and so can't track the issue down
further, but I was hoping someone who has seen this before might know of a
quick work around that they could let me in on (short of removing the tabs
of course).  Any help appreciated, and once again thanks for all the work.

 

Warm wishes,

Nigel

Mono link to Apache

rcam — 2013-01-06T21:08:50

I am totally new to Mono. I was reading about it a little and I was
wondering...
Can Apache use mono to open asp.net (asp, aspx...etc) pages for webhosting ?

If yes, How do I install it and link Mono to apache V 2.4.3 on Windows?

If someone can give me some detailed instructions I would be very great full
since I am new to all of apache and mono.

Thanks

Accessing Outlook Calendar API in MAC OS

nks_33 — 2012-08-10T13:46:03

Hi,

I am currently writing an application in C#.Net(Windows + Mono Develop) to
access all calendar events in my outlook. Now I want to port the application
in MAC OS using Mono. But I am getting "Microsoft.Office.Interop.Outlook"
namespace not found error in Mac. Can you please suggest me how to get rid
of this problem in MAC OS so that I can get all calendar events
(appointments, meetings etc) that I am already getting in Windows platform.

Thanks

SQL SERVER 2008 - IDbConnection.Open exception

I am porting an existing .net app to be ran in macosx.

Both my code and example code in(http://www.mono-project.com/SQLClient fail

          "Password=pwd;";

This code works fine when "normal-run" in VS2010 but fails when mono-run.
Here's the exception:

Mono-program which can be started on different distributions of Linux

tumanovalex — 2012-06-12T10:37:40

I created the project in Windows in VS2010, transferred it to Mono on Linux
Mint, everything is normally compiled and works. It would be desirable to
make now so that the created program worked at different distribution kits
of Linux without installation on them additional libraries or Mono. Probably
it is necessary to introduce somehow in it libraries or to drag it with
libraries (that will arrange also, and other option). To Linux passed
recently so as it to make, I do not know. Prompt, please, as it can be done,
it is desirable in more detail: what Mono files need to be taken, as them to
process etc.

iis to mono webservice not working

hugopq — 2012-06-11T18:56:22

Hi

I'm new to mono and i'm trying to get a webservice to work.
I'm developping in windows using IIS and it works, but when I upload to the
server (which uses mono) i can't make it work and don't understand why,

This is my service, it just returns a string:

using System;
using System.Collections.Generic;

using System.Web.Services;
