Hi,
This is probably going to be a very silly question. Why are using VisualStudio
at all with LBC?

Subject: SV: Layout by code - a wonderfull tool but....
Hi again,
Further to my problem with Layout by code.
This time I tried the original FruitBasketCS program without modifications.
When I go into the project properties and set output type to console
application everything runs nicely, except for the anoying fact that a
console window is created for the program which is not used anyway. When I
change the output type to Windows Application the previously mentioned
"invalid cast exception" occurs. Still, I can step through the program by
using f10 and f11.
In the meantime I also found out that the so-called ParkingWindow apparently
seems to be an invisible window, a kind of clip-board that is used when you
move controls from one window to another. I must admit that I am getting
more and more confused
I hope someone can help me, please. I still think that using Layout by Code
would be a great way for a blind person to make a user interface with a
decent layout
Best regards
Bue

Emne: Layout by code - a wonderfull tool but....
Hi,
First of all a million thanks to Jamal for his great work. LBC is just about
the most fantastic programming tool I have ever stumbled upon. I am
congenitally blind and have always found it next to imposible to work out a
layout that would work at all.
Now for my problem:
I am trying to make a template for use with Visual Studio 2008 building on
the template for a Windows forms application. Everything compiles fine, but
when I run the resulting program I get the following exception (translated
from Danish):
Invalid cast exception
{"an object of the type
'Microsoft.VisualStudio.HostingProcess.ParkingWindow' can not be converted
to the type 'Homer.LbcForm'."}
The exception occurs at the CompleteWindow() call. It looks to me as if I
was referencing the form before it is actually created. The funny thing is
that everything works fine when I step into the code using f10 and f11. I
don't suppose there could be a race condition? Hope someone can help me.
Below is the code I am using. As I said, it is built on the Windows form
application template. I thought that the use of component initialization
might be the cause of my trouble, so I tried to remove all the designer and
component stuff, but it didn't solve anything.
LbcForm1.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Homer;
namespace LBCFormsApplication1
{
public partial class LbcForm1 : LbcForm
{
public LbcForm1()
{
InitializeComponent();
this.Init("LbcForm1", null, null);
this.AddMyControlls();
}
Private void AddMyControlls()
{
// Add controlls here.
// AddButton("ok");
}
public void OnEvent(string sEvent, Control oSender,
EventArgs oArgs)
{
// Add event code here.
}
}
}
LbcForm1.Designer.cs
namespace LBCFormsApplication1
{
partial class LbcForm1
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should
be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.components = new
System.ComponentModel.Container();
this.AutoScaleMode =
System.Windows.Forms.AutoScaleMode.Font;
}
#endregion
}
}
Program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
namespace LBCFormsApplication1
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
LbcForm1 oLbcForm = new LbcForm1();
// Add further initialization here.
// Uncomment to run as window.
oLbcForm.CompleteWindow();
// Uncomment to run as dialog.
// oLbcForm.CompleteDialog();
}
}
}
Best regards
Bue
