loadrunner中大小写字符转换函数封装：

//封装ConvertToXXX函数：

int ConvertToUpper(char * sInput, char * sNew)

{

 sInput = (char *)strupr(sInput);

 lr_save_string(sInput,sNew);

}

int ConvertToLower(char * sInput, char * sNew)

{

 sInput = (char *)strlwr(sInput);

 lr_save_string(sInput,sNew);

}

int ConvertToTitle(char * sInput, char * sNew)

{

 int i = 0, s = 0, l = 0;

 char buf1[50];

 char buf2[2];

 char n;

 strncpy(&n,sInput+i,1);

 sprintf(buf2,"%c",n);

 strupr(buf2);

 strcpy(buf1,buf2);

 i++;

 while(i < strlen(sInput))

 {

  strncpy(&n,sInput+i,1);

  sprintf(buf2,"%c",n);

  if(s == 1){

   strupr(buf2);

   strcat(buf1,buf2);

   s = 0;

  }

  else{

   strlwr(buf2);

   strcat(buf1,buf2);

  }

  if(strcmp(" ",buf2)==0)

  {

   s = 1;

  }

  i++;

 }

 lr_save_string(buf1,sNew);

}

login()

 lr_save_string("testing is believing","str");

       ConvertToUpper(lr_eval_string("{str}"),"UpperStr");

       lr_output_message(lr_eval_string("{UpperStr}"));
