调试秘笈--MessageBox()格式化输出,windows程序支持命令行输出

这是MessageBox的全家福:

 格式化输出:

int BoxPrintf( TCHAR * szBuffer, const TCHAR * szFormat, ...)
{
    int     iReturn ;         
    va_list pArgs ;        
    va_start (pArgs, szFormat) ;        
    iReturn = wvsprintf (szBuffer, szFormat, pArgs) ;   
    va_end (pArgs) ;            //wvsprintf参数三为va_list,而wsprintf为"..."
    MessageBox(NULL,szBuffer,TEXT("message"),MB_OK|MB_TOPMOST) ;    
   return iReturn ;
}

发声:
//MessageBeep (MB_ICONWARNING);//轻dideng
//MessageBeep (MB_ICONASTERISK );//dideng
//MessageBeep ( MB_OK );//DENG,同-1
//MessageBeep ( MB_ICONHAND );//HONG,出错音
//MessageBeep (-1 );//DENG,全拼输入无汉字音
//MessageBeep ( MB_ICONQUESTION );//无声

下面是测试 int MessageBox(HWND hWnd,LPCTSTR lpText,LPCTSTR lpCaption,UINT uType);的标志位

//cl msg.cpp  /EHsc

#include "windows.h"
#include "iostream" 
#include   "string"

#pragma comment(lib,"user32.lib")
using namespace std;
void showMenu()
{
	cout<<endl<<"-------测试 int MessageBox(HWND hWnd,LPCTSTR lpText,LPCTSTR lpCaption,UINT uType);中的uType--------"<<endl;
	cout<<"0.EXIT"<<endl;
	cout<<"1.MB_OK"<<endl;
	cout<<"2.MB_ICONEXCLAMATION"<<endl; 
	cout<<"3.MB_ICONWARNING"<<endl; 
	cout<<"4.MB_ICONQUESTION"<<endl;

	cout<<"a.MB_SETFOREGROUND"<<endl; 
	cout<<"b.MB_TOPMOST"<<endl; 
	cout<<"c.MB_SYSTEMMODAL"<<endl; 

	cout<<"-测试 int MessageBox(HWND hWnd,LPCTSTR lpText,LPCTSTR lpCaption,UINT uType);的按键与返回值---"<<endl;
	cout<<"d.MB_ABORTRETRYIGNORE"<<endl;
	cout<<"e.MB_OK"<<endl;
	cout<<"f.MB_OKCANCEL"<<endl;
	cout<<"g.MB_RETRYCANCEL"<<endl;
	cout<<"h.MB_YESNO"<<endl;
	cout<<"i.MB_YESNOCANCEL"<<endl;

 让WINDOWS程序支持命令行输出:(来自:女孩不哭的串口调试助手common)

在初始化时加入
case WM_CREATE:
               AllocConsole();
				break;
在结束时加入
case WM_DESTROY:
               FreeConsole();
				break;

加入定义:
#pragma warning (disable:4996)// warning C4996: '_vsnprintf': This function or variable may be unsafe. Consider using _vsnprintf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
#include <stdio.h>
void cmdpf(TCHAR* fmt, ...)
{	
        TCHAR buf[1024] = {0};
        va_list va;
        int len,dw;
        va_start(va, fmt);
        len=wvsprintf(buf,fmt,va);
        WriteConsole(GetStdHandle(STD_OUTPUT_HANDLE),buf,len,(LPDWORD)&dw,NULL);
}

然后我们就可以在WINDOWS窗口程序中插入命令行输出,更方便调试
