问题描述

如何在 Visual Studio 2010 ?

推荐答案

严格回答您的问题，您可以使用 winbase.h OutputDebugString函数.

Strictly answering your question, you may use printf-like functions in a Win32 application in Visual Studio 2010 using the winbase.h OutputDebugString function.

我写了一个简单的程序来演示如何做.

I wrote a simple program that shows how to do it.

#include <windows.h>
#include <stdio.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdShow, int nCmdShow)
{
    int number = 10;
    char str[256];
    sprintf_s(str, "It works! - number: %d \n", number);

    OutputDebugString(str);

    return 0;
}

OutputDebugString函数将LPCSTR作为参数.我在打印前用sprintf_s格式化了字符串.

The OutputDebugString function takes an LPCSTR as a parameter. I used the sprintf_s to format the string before printing.

这会将结果打印到Visual Studio 2010输出窗口.

This would print the result to the Visual Studio 2010 output window.
