小弟是一新手，您能不能对您的程序作一下注解：
#pragma code ("UseGen.DLL")

#include "usegenap.h"

#pragma code ()



char szUserName[255];

char szPassword[255];

char szNewPassword[255];

char szVerifyPassword[255];

CMN_ERROR err;

CMN_ERROR error;



strcpy(szUserName,GetInputValueChar(lpszPictureName,"@LoginIn"));

strcpy(szPassword,GetInputValueChar(lpszPictureName,"@PasswordIn"));

strcpy(szNewPassword,GetInputValueChar(lpszPictureName,"@NewPasswordIn"));

strcpy(szVerifyPassword,GetInputValueChar(lpszPictureName,"@VerifyPasswordIn"));



if (PWRTSilentLogin(szUserName,szPassword) == FALSE)

{

SetOperation(lpszPictureName,"@OK",FALSE);

SetOperation(lpszPictureName,"@LoginIn",FALSE);

SetOperation(lpszPictureName,"@PasswordIn",FALSE);

SetOperation(lpszPictureName,"@NewPasswordIn",FALSE);

SetOperation(lpszPictureName,"@VerifyPasswordIn",FALSE);



SetVisible(lpszPictureName,"@ERROR",TRUE);

SetVisible(lpszPictureName,"@REPEAT",TRUE);

Set_Focus(lpszPictureName,"@REPEAT");

}

else

{

PWGENConnect("CC_s7_04_08_16_10_55_13R", &err);



PWGENChangePassword( szUserName,szPassword,szNewPassword, &error);



PWGENDisconnect(&err);



}

是不是密码和用户是存在数据库中，所以有这句：

PWGENConnect("CC_s7_04_08_16_10_55_13R", &err);



PWGENChangePassword( szUserName,szPassword,szNewPassword, &error);



PWGENDisconnect(&err);
