Hi to all,
I Create ClassLibrary with name Test and Added User Control Named it as User. In class1.cs I wrote Code...
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using Sage.SalesLogix.NetExtensions.Licensing;
using Sage.SalesLogix.NetExtensions;
namespace Test
{
public class Class1 : Sage.SalesLogix.NetExtensions.BaseRunnable
{
public override object Run(object[] Args)
{
return null;
}
}
}
I had loader Class
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using Sage.SalesLogix.NetExtensions;
namespace Test
{
[ComVisible(true), ProgId("Test.USer")]
public class Loader
{
User _ctrl = null;
public void Init(object handle)
{
if (handle != null)
{
IntPtr hwnd = new IntPtr((int)handle);
if (_ctrl == null)
_ctrl = new User();
Win32.SetParent(_ctrl.Handle, hwnd);
ResizeControl(hwnd);
}
}
private void ResizeControl(IntPtr handle)
{
Win32.RECT rect;
Win32.GetWindowRect(handle, out rect);
if (Win32.GetWindowRect(handle, out rect) && _ctrl != null)
{
_ctrl.Size = rect.Size;
}
}
public string ID
{
set
{
if (_ctrl != null)
{
_ctrl.Name = value;
}
}
}
}
}
Win 32 Code..
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Drawing;
namespace Test
{
internal class Win32
{
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool GetWindowRect(IntPtr hWnd, out RECT lpRect);
[Serializable, StructLayout(LayoutKind.Sequential)]
public struct RECT
{
public int Left;
public int Top;
public int Right;
public int Bottom;
public RECT(int left_, int top_, int right_, int bottom_)
{
Left = left_;
Top = top_;
Right = right_;
Bottom = bottom_;
}
public int Height { get { return Bottom - Top; } }
public int Width { get { return Right - Left; } }
public Size Size { get { return new Size(Width, Height); } }
public Point Location { get { return new Point(Left, Top); } }
public Rectangle ToRectangle()
{ return Rectangle.FromLTRB(Left, Top, Right, Bottom); }
public static RECT FromRectangle(Rectangle rectangle)
{ return new RECT(rectangle.Left, rectangle.Top, rectangle.Right, rectangle.Bottom); }
public static implicit operator Rectangle(RECT rect)
{ return Rectangle.FromLTRB(rect.Left, rect.Top, rect.Right, rect.Bottom); }
public static implicit operator RECT(Rectangle rect)
{ return new RECT(rect.Left, rect.Top, rect.Right, rect.Bottom); }
public override int GetHashCode()
{
return Left ^ ((Top << 13) | (Top >> 0x13))
^ ((Width << 0x1a) | (Width >> 6))
^ ((Height << 7) | (Height >> 0x19));
}
}
}
}
User.Cs Code..
using System.Data.OleDb;
using System.IO;
using System.Drawing.Imaging;
using System.Runtime.InteropServices;
namespace Test
{
public partial class User : UserControl
{
public User()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
label1.Text = "Welcome to SalesLogix";
}
}
}
User.Desginer.cs
namespace Test
{
partial class User
{

}
base.Dispose(disposing);
}
#region Component Designer generated code

this.button1 = new System.Windows.Forms.Button();
this.label1 = new System.Windows.Forms.Label();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new System.Drawing.Point(43, 28);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// label1
//
this.label1.AutoSize = true;
this.label1.Location = new System.Drawing.Point(83, 95);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(35, 13);
this.label1.TabIndex = 1;
this.label1.Text = "label1";
//

//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.Controls.Add(this.label1);
this.Controls.Add(this.button1);
this.Name = "User";
this.Size = new System.Drawing.Size(213, 150);
this.ResumeLayout(false);
this.PerformLayout();
}
#endregion
private System.Windows.Forms.Button button1;
private System.Windows.Forms.Label label1;
}
}
In Slx Architect I wrote Form open Event code like this
Dim loader
If Application.GlobalInfo.IndexOf("USerObject")= -1 Then
Set loader = CreateObject("Test.User")
loader.Init panelEmbed.HWND
Application.GlobalInfo.Add "USerObject", loader
Set loader = Nothing
Else
Set loader = Application.GlobalInfo("USerObject")
Set loader = Nothing
End If
I got Error ActiveX Component Canot Create Object .
I tried Another Way also but It does not throw any error but I didnot get Any thing..
i.e
Dim ext ' this variable will hold the handle for the loaded .NET Extension
' instanciate the .NET Extension
ext = Application.Managed.Create("SLX NET Extensions Test", "ClassLibrary1.Class1")
' run it (and pass any arguments)
Application.Managed.Run ext, "Hello from Architect"
' destroy the loaded .NET Extension
Application.Managed.Destroy ext
But It doesnot through Error But I didnot get Result...
Please help me It is very Urgent to me...
Regards,
Venkateswararao...
