直接给出实例：

void CK390_TestApp::OnGprsTest(){// TODO: Add your command handler code hereint dwRet=0;HDC hdc;hdc = CreateDC(0,0,0,0);//获得设备句柄RETAILMSG(1,(_T("GPRS Test./n")));InitGPIOAddr();//232CTR->GPJ9 =0 -> GPRS//GSMPWR->GPJ11=1//GSMOP1->GPJ10=0//WAKE ->GPJ12=0s2440IOP->GPJCON = ((s2440IOP->GPJCON &~ (0x3<<18)) | (1<<18)); s2440IOP->GPJDAT &=~(1<<9);s2440IOP->GPJCON = ((s2440IOP->GPJCON &~ (0x3<<22)) | (1<<22)); s2440IOP->GPJDAT &=~(1<<11);Sleep(100);s2440IOP->GPJDAT |=(1<<11);s2440IOP->GPJCON = ((s2440IOP->GPJCON &~ (0x3<<20)) | (1<<20)); s2440IOP->GPJDAT &=~(1<<10);s2440IOP->GPJCON = ((s2440IOP->GPJCON &~ (0x3<<24)) | (1<<24)); s2440IOP->GPJDAT &=~(1<<12);Sleep(100);s2440IOP->GPJDAT |=(1<<12);Sleep(350);s2440IOP->GPJDAT &=~(1<<12);dwRet=ExtTextOut(hdc, 0, 140, ETO_CLIPPED, NULL, _T("K390 test."), strlen("K390 test."), NULL); if(dwRet==0){dwRet = GetLastError();printf("error = %d ../n", dwRet);}if(!COMInit()){printf("COMInit ERROR!!/r/n");}else{char *recvAt[1];char tmpbuf[3]="OK";int i=0;//char BufTest[3]="OK";TCHAR BufTest[3];i=MultiByteToWideChar(CP_ACP,0,tmpbuf,-1,BufTest,0);i=MultiByteToWideChar(CP_ACP,0,tmpbuf,-1,BufTest,i);//memcpy(BufTest,tmpbuf,strlen(tmpbuf));ExtTextOut(hdc, 0, 100, ETO_CLIPPED, NULL,BufTest, _tcslen(BufTest), NULL); recvAt[0] = tmpbuf;int ret=0;//ret = GPRS_AT("AT",recvAt,1);ret = GPRS_AT("AT+GMI",recvAt,1);//lqm test.if(ret == -3)printf("GPRS_AT ret =%d/r/n",ret);}DeleteDC(hdc);}

两句MultiByteToWideChar()函数解决char到TCHAR的问题。

转换的目的在于ExtTextOut()函数能够正常输出char字符。
