Win32 控制台应用程序是否可以检测它是否已从资源管理器运行?

问题描述

我必须创建一个需要某些参数的控制台应用程序.如果它们丢失或错误，我会打印出错误消息.

I have to create a console application which needs certain parameters. If they are missing or wrong I print out an error message.

现在的问题:如果有人通过双击从资源管理器启动程序，控制台窗口会立即消失.(但该应用程序在资源管理器中并非完全没用，您可以将文件拖到它上面就可以了)

Now the problem: If someone starts the program from the explorer by double-clicking the console window disappears immediately. (But the application is not entirely useless from the explorer, you could drag files onto it and it would work)

我可以总是等待按键，但如果用户确实从命令行启动它，我不希望这样.

I could always wait for a keypress, but I don't want that if the user did start it from the command line.

有什么方法可以区分这些情况吗?

Is there some way to distinguish between these situations?

推荐答案

参见 http://support.microsoft.com/kb/99115，信息:防止控制台窗口消失".

See http://support.microsoft.com/kb/99115, "INFO: Preventing the Console Window from Disappearing".

想法是使用GetConsoleScreenBufferInfo 来确定光标没有从最初的0,0 位置移动.

The idea is to use GetConsoleScreenBufferInfo to determine that the cursor has not moved from the initial 0,0 position.

来自@tomlogic 的代码示例，基于参考的知识库文章:

Code sample from @tomlogic, based on the referenced Knowledge Base article:

// call in main() before printing to stdout
// returns TRUE if program is in its own console (cursor at 0,0) or
// FALSE if it was launched from an existing console.
// See http://support.microsoft.com/kb/99115
#include <stdio.h>
#include <windows.h>
int separate_console( void)
{
    CONSOLE_SCREEN_BUFFER_INFO csbi;

    if (!GetConsoleScreenBufferInfo( GetStdHandle( STD_OUTPUT_HANDLE), &csbi))
    {
        printf( "GetConsoleScreenBufferInfo failed: %lu
", GetLastError());
        return FALSE;
    }

    // if cursor position is (0,0) then we were launched in a separate console
    return ((!csbi.dwCursorPosition.X) && (!csbi.dwCursorPosition.Y));
}
