[Mono-winforms-list] How to setup Winforms support under Windows

[Graeme Geldenhuys]

Hi Peter,

The application is basically a "Hello world" style app.  Just a single form and a single button. 
Nothing else.

Not sure what I did, but now I got a actual error saying that I am missing the gdiplus.dll file.

Is there supposed to be a gdiplus.dll file in the <mono install>\bin directory (windows version 
of mono).  By default there wasn't.  I then searched my harddrive and found one in the WinNT 
directory structure (C:\WINNT\Microsoft.NET\Framework\v1.1.4322\gdiplus.dll).  I copied it to the 
<mono install>\bin folder, and now my test app seem to work.

Doesn't the windows install of mono include the gdiplus.dll?  If not, then it means I need to 
install the Microsoft .NET framework and the Mono Framework under Windows, just to get the 
applications working...  This doesn't sound right?


The following example still doesn't work though....  Using the MS .NET framework it does, but not 
under Mono.  I don't think you can get a more basic application than this. :-)

---------------  CUT  ----------------------------
class HelloWindowsForms
{
    static void Main()
    {
        System.Windows.Forms.MessageBox.Show("Welcome to the bill free zone.");
    }
}
---------------  END  ----------------------------

Compiled with:
mcs HelloWinForms.cs /r:System.Windows.Forms.dll /r:System.Drawing.dll /target:winexe

Executed as:
mono HelloWinForms.exe

Error received:
