运行没有控制台窗口的Windows应用程序

本文介绍了运行没有控制台窗口的Windows应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在创建一个实用程序，它将从另一个将提供命令行参数的应用程序启动，但是当它被激活时，会出现一个控制台窗口，我能够做的最好的事情就是使用互操作服务让它短暂闪存。 我需要应用程序在激活时显示表单而不是控制台窗口。我知道必须有办法做到这一点！ 我还需要激活的实用程序应用程序根据用户输入返回一个值。 下面是我开始工作的代码，但现在却没有？，显示控制台窗口并且它保持正常状态然后消失了？

[DllImport（ kernel32.dll）] 静态 extern IntPtr GetConsoleWindow（）; [DllImport（ user32.dll）] static extern bool ShowWindow（ IntPtr hWnd， int nCmdShow）; const int SW_HIDE = 0 ; const int SW_SHOW = 5 ; public Form1（ string [] args） { InitializeComponent（）; // 隐藏 var handle = GetConsoleWindow（）; ShowWindow（handle，SW_HIDE）; PositionNotifyWindow（）; string html = < center>< h3>测试一下< / h3>< / center>; string htm = < h3 style = \text-align：center \> WTF发生了什么？< / h3>; webBrowser1.DocumentText = html + htm; ; }

任何帮助非常感谢！

解决方案

你的逻辑在哪里？如果你不想要控制台，为什么要使用 GetConsoleWindow ？如果您使用的是表单，为什么要使用 ShowWindow ？您根本不应该使用P / Invoke，只使用纯.NET FCL，否则会损害您的平台兼容性，而不会得到任何回报。 命令-line参数与控制台无关。也许你的问题不是理解这个非常明显的事实。要在接收它们的应用程序中使用命令行参数，请参阅我的文章：枚举 - 基于命令行实用程序 [ ^ ]。 您不必使用我的实用程序或我的任何代码，您只需学习如何获取命令行参数通过入口点（ Main ）和 System.Environment 传递。

虽然我不确定我到底知道你在做什么，或者:)，我在实现代码方面没有遇到任何麻烦像这样： 1.在主应用程序中：

private string path = @ 辅助应用程序的ValidPathToExe; private void button1_Click（对象发​​件人，EventArgs e） { // 必须是有效的URI ，即，从以下开始：http：// ... Process.Start（路径， @ www.google）; }

2.在具有WebBrowser控件的辅助应用程序中：

private void Form1_Load（ object sender，EventArgs e） { string [] args = Environment.GetCommandLineArgs（）; if （args.Length > 0 ） { // 仅供测试 // foreach（args中的字符串arg）MessageBox.Show（arg）; if （args.Length > 1 ） { Uri uriResult; bool result = Uri.TryCreate（args [ 1 ]，UriKind。绝对， out uriResult）&& （uriResult.Scheme == Uri.UriSchemeHttp || uriResult.Scheme == Uri.UriSchemeHttps）; if （result） { webBrowser1.Navigate（args [ 1 ]）; } else { MessageBox.Show（ 无效的网址）; } } } else { MessageBox.Show（ 未收到有效的文件路径）; } }

我假设您可以使用'Process Class的标准属性来启用从二级Process'表单接收通知事件...如EnableRaisingEvents，创建一个OutputDataReceived事件的处理程序，重定向标准输出等。 如果这个响应是离开，请告诉我，我会删除它。 用于处理.NET进程的有趣的异步覆盖：[ ^ ]。关于MedallionShell开发的文章：[ ^ ]。

I'm creating a utility that will be started from another application that will supply command line arguments but when it's activated a console window appears and the best I've been able to do is to get it to flash briefly using interop services. I need for the application to display a form when it's activated but not the console window. I know there has to be a way to do this! I also need for the activated utility application to return a value depending on user input. Below is the code that I was getting to work but now it doesn't?, show the console window and it stays up was coming up briefly then disappearing?

[DllImport("kernel32.dll")] static extern IntPtr GetConsoleWindow(); [DllImport("user32.dll")] static extern bool ShowWindow(IntPtr hWnd, int nCmdShow); const int SW_HIDE = 0; const int SW_SHOW = 5; public Form1(string[] args) { InitializeComponent(); // Hide var handle = GetConsoleWindow(); ShowWindow(handle, SW_HIDE); PositionNotifyWindow(); string html = "<center><h3>Testing this out</h3></center>"; string htm = "<h3 style=\"text-align: center\">WTF Happened?</h3>"; webBrowser1.DocumentText = html + htm; ; }

Any help much appreciated!

解决方案

Where is your logic? If you don't want the console, why using GetConsoleWindow? If you are using Forms, why using ShowWindow? You should not use P/Invoke at all, use just pure .NET FCL, otherwise you will compromise your platform compatibility, not getting anything at all in return. Command-line parameters have nothing to do with console. Perhaps your problem was not understanding this very obvious fact. To work with command-line parameters in the application receiving them, please see my article: Enumeration-based Command Line Utility[^]. You don't have to use my utility or any of my code, you can just learn how to get the command-line parameters passed, through entry point (Main) and System.Environment.

While I'm not sure I understand exactly what you are doing, either :), I have had no trouble implementing code like this: 1. in the primary Application:

private string path = @"ValidPathToExe of Secondary App"; private void button1_Click(object sender, EventArgs e) { // must be a valid URI, i.e., starts with: ... Process.Start(path, @"www.google"); }

2. in the secondary Application with a WebBrowser Control:

private void Form1_Load(object sender, EventArgs e) { string[] args = Environment.GetCommandLineArgs(); if (args.Length > 0) { // for testing only //foreach (string arg in args) MessageBox.Show(arg); if (args.Length > 1) { Uri uriResult; bool result = Uri.TryCreate(args[1], UriKind.Absolute, out uriResult) && (uriResult.Scheme == Uri.UriSchemeHttp || uriResult.Scheme == Uri.UriSchemeHttps); if (result) { webBrowser1.Navigate(args[1]); } else { MessageBox.Show("invalid url"); } } } else { MessageBox.Show("no valid file path received"); } }

I am assuming that you could use standard properties of the 'Process Class to enable receiving notification Events from the secondary Process' Form ... like EnableRaisingEvents, creating a handler for the OutputDataReceived Event, re-directing standard output, etc. If this response is "way off," just let me know, and I'll delete it.
