dll内的表格未显示 [英] Form inside a dll not showing

问题描述

我正在尝试显示DLL中的一种形式....这是DLL TestApp中的代码.下面是TestApp内部的DLLNew类的代码.我无法更改代码，因为它是DLL.请帮帮我.

I am trying to show a form which is inside a DLL .... This is the code inside a DLL TestApp . Below is the code of class DLLNew inside TestApp . I am unable to change the code as it is a DLL . please help me out .

<pre lang="c#">using Microsoft.VisualBasic;
using Microsoft.VisualBasic.CompilerServices;
using System;
using System.Drawing;
using System.IO;
using System.Runtime.InteropServices;
using System.Security.Cryptography;
using System.Text;
using System.Windows.Forms;

namespace TestApp
{
	public class DLLNew
	{
		private frmPIN PinForm;
		public DLLNew()
		{
			this.PinForm = new frmPIN();

		private static List<WeakReference> __ENCList = new List<WeakReference>();

		public ToolTip ToolTip1;

预先感谢.

Thanks in advance .

推荐答案

创建表单实例不会显示它-您需要先调用Show或ShowDialog方法，然后才能显示它.您的代码创建一个实例，但它不会尝试显示它.

通常，这样做是为了可以在显示表单之前设置选项，就像显示OpenFileDialog一样:

Creating a form instance does not display it - you need to call either the Show or the ShowDialog method before it will be displayed. Your code creates an instance, but it does not try to display it.

Normally, this is so that options can be set before the form is displayed, much as you do with you display a OpenFileDialog:

OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = StaticMethods.MakeFilter("Music files", new string[] { "mp3", "wmv", "wav" });
ofd.Multiselect = true;
if (ofd.ShowDialog() == DialogResult.OK)
    {
    ...
    }
