I am sorry the title isn't very descriptive but I have several questions and couldn't come up with a good title.

1. When I add a winform to my project there are two files created, a cs file and a resx. What is the purpose of the resx file? Do I need to check that file into VSS or is this file generated by VS.NET when I view the form in the designer?

2. I want to create a generic form with a crystal preview control on it. I will then call upon this form from several applications when I want to preview a report. So what I did was to add a winform to my project and add a crystal preview control. Below is the code generated:

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;

namespace ALS.Crystal
{
	/// <summary>
	/// Summary description for ALS.
	/// </summary>
	public class frmPreview : System.Windows.Forms.Form
	{
		private CrystalDecisions.Windows.Forms.CrystalReportViewer crViewer;
		/// <summary>
		/// Required designer variable.
		/// </summary>
		private System.ComponentModel.Container components = null;

		public frmPreview()
		{
			InitializeComponent();

		}

		/// <summary>
		/// Clean up any resources being used.
		/// </summary>
		protected override void Dispose( bool disposing )
		{
			if( disposing )
			{
				if(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.crViewer = new CrystalDecisions.Windows.Forms.CrystalReportViewer();
			this.SuspendLayout();
			// 
			// crViewer
			// 
			this.crViewer.ActiveViewIndex = -1;
			this.crViewer.Dock = System.Windows.Forms.DockStyle.Fill;
			this.crViewer.Location = new System.Drawing.Point(0, 0);
			this.crViewer.Name = "crViewer";
			this.crViewer.ReportSource = null;
			this.crViewer.Size = new System.Drawing.Size(292, 266);
			this.crViewer.TabIndex = 0;
			// 
			// frmPreview
			// 
			this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
			this.ClientSize = new System.Drawing.Size(292, 266);
			this.Controls.Add(this.crViewer);
			this.Name = "frmPreview";
			this.Text = "Preview";
			this.ResumeLayout(false);

		}
		#endregion
	}
}

What code do I need for this form to display? Should I make the crystal preview control public (so I can change ReportSource and other settings) or should I add my own public method where I can set these things?

How do you deal with previewing crystal reports?

Any other comments related to crystal preview control and forms would be appreciated.

Thanks,
Einar
