C＃窗体不呈现控件

我有一个像这样的小popup窗口：

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; namespace SQLProcWriter { public partial class Progress : Form { public Progress() { InitializeComponent(); progressBar1.Minimum = 0; progressBar1.Maximum = 100; } } } namespace SQLProcWriter { partial class Progress { /// <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() { System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Progress)); this.progressBar1 = new System.Windows.Forms.ProgressBar(); this.label1 = new System.Windows.Forms.Label(); this.SuspendLayout(); // // progressBar1 // resources.ApplyResources(this.progressBar1, "progressBar1"); this.progressBar1.Name = "progressBar1"; this.progressBar1.UseWaitCursor = true; // // label1 // resources.ApplyResources(this.label1, "label1"); this.label1.Name = "label1"; this.label1.UseWaitCursor = true; // // Progress // resources.ApplyResources(this, "$this"); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.Controls.Add(this.label1); this.Controls.Add(this.progressBar1); this.Name = "Progress"; this.UseWaitCursor = true; this.ResumeLayout(false); this.PerformLayout(); } #endregion public System.Windows.Forms.ProgressBar progressBar1; public System.Windows.Forms.Label label1; } } 

它应该显示我正在加载和处理的文件的进度。 问题是在文件完成处理之前，它不呈现进度条或标签; 该窗体在主窗口的加载方法上创build，并且一旦openfiledialog完成并显示“OK”结果，就会显示该窗体。 任何帮助？

编辑：值的设置代码是相当广泛的，所以我原来select删除它，但在这里是：

• 在窗体中绘制带有resize点的控件select矩形
• Autocad不同的API的混乱
• 为什么Windows 8没有.NET Framework 2.0和3.5内置？
• WindowsPrincipal.IsInRole考虑到组内的组？
• 在FAXCOMEX LIb的C＃实现中System.Runtime.InteropServices.COMException错误

 //Indicate that the process has started Invoke(ShowStatusDelegate, this.toolStripStatusLabelSpinner, true, this.toolStripStatusLabelText, "In progress...", btnGo, false);
