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, ...){intiReturn ; 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<<"5.MB_ICONSTOP"<<endl; cout<<"6.MB_ICONERROR"<<endl; cout<<"7.MB_ICONHAND"<<endl; cout<<"8.MB_ICONASTERISK"<<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;}struct RETVALUE{UINT uType;string typeName;} retValue[]={IDABORT,"IDABORT",IDCANCEL,"IDCANCEL",IDIGNORE,"IDIGNORE",IDIGNORE,"IDIGNORE",IDNO,"IDNO",IDOK,"IDOK",IDRETRY ,"IDRETRY",IDYES,"IDYES",};int main(){int key=0,ret=0;bool bQuit=false;while(!bQuit){showMenu();cout<<"选择并回车:";key=cin.get();switch(key){case '0':bQuit=true;break;case '1':ret=MessageBox(NULL,TEXT("MB_OK"),TEXT("test.1"), MB_OK);break;case '2':ret=MessageBox(NULL,TEXT("MB_ICONEXCLAMATION"),TEXT("test.2"),MB_ICONEXCLAMATION);break;case '3':ret=MessageBox(NULL,TEXT("MB_ICONWARNING"),TEXT("test.3"),MB_ICONWARNING);break;case '4':ret=MessageBox(NULL,TEXT("MB_ICONQUESTION"),TEXT("test.4"),MB_ICONQUESTION);break;case '5':ret=MessageBox(NULL,TEXT("MB_ICONSTOP"),TEXT("test.5"),MB_ICONSTOP);break;case '6':ret=MessageBox(NULL,TEXT("MB_ICONERROR"),TEXT("test.6"),MB_ICONERROR);break;case '7':ret=MessageBox(NULL,TEXT("MB_ICONHAND"),TEXT("test.7"),MB_ICONHAND);break;case '8':ret=MessageBox(NULL,TEXT("MB_ICONASTERISK"),TEXT("test.8"),MB_ICONASTERISK);break;case '9':ret=MessageBox(NULL,TEXT("MB_ICONINFORMATION"),TEXT("test.9"),MB_ICONINFORMATION);break;case 'A':case 'a':ret=MessageBox(NULL,TEXT("MB_SETFOREGROUND"),TEXT("appear top.a"),MB_SETFOREGROUND);break;case 'B':case 'b': ret=MessageBox(NULL,TEXT("MB_TOPMOST"),TEXT("almost top.b"),MB_TOPMOST);break;case 'C':case 'c':ret=MessageBox(NULL,TEXT("MB_SYSTEMMODAL"),TEXT("almost top.c"),MB_SYSTEMMODAL);break;case 'D':case 'd':ret=MessageBox(NULL,TEXT("MB_ABORTRETRYIGNORE"),TEXT("test ret.d"),MB_ABORTRETRYIGNORE);break;case 'E':case 'e':ret=MessageBox(NULL,TEXT("MB_OK"),TEXT("test ret.e"),MB_OK);break;case 'F':case 'f':ret=MessageBox(NULL,TEXT("MB_OKCANCEL"),TEXT("test ret.f"),MB_OKCANCEL);break;case 'G':case 'g':ret=MessageBox(NULL,TEXT("MB_RETRYCANCEL"),TEXT("test ret.g"),MB_RETRYCANCEL);break;case 'H':case 'h':ret=MessageBox(NULL,TEXT("MB_YESNO"),TEXT("test ret.h"),MB_YESNO);break;case 'I':case 'i':ret=MessageBox(NULL,TEXT("MB_YESNOCANCEL"),TEXT("test ret.i"),MB_YESNOCANCEL);break;}for(int i=0;i<sizeof(retValue)/sizeof(retValue[0]);i++){if(retValue[i].uType==ret){cout<<"返回值 ret="<<ret<<"即:"<<retValue[i].typeName<<endl;}}}return 0;}

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
