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<<"9.MB_ICONINFORMATION"<<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
