HC-204 along with 433 MHz tranmitter receiver- char -char*

Hello!
I am trying to measure the distance of an object using HC-204 and then transmit it over 433Mhz, transmitter receiver using Virtual wire library.
Just sending a string of "hello" works, also the distance can be obtained individually, however combining the code gives an error:
Arduino: 1.6.5 (Windows 7), Board: "Arduino Uno"

sketch_jul28ainte.ino: In function 'void loop()':
sketch_jul28ainte:39: error: invalid conversion from 'char' to 'char*' [-fpermissive]
sketch_jul28ainte:15: error: initializing argument 1 of 'void send(char*)' [-fpermissive]
invalid conversion from 'char' to 'char*' [-fpermissive]

I have typed in the code here:
#include <VirtualWire.h>
#define trigPin 13
#define echoPin 12
#define led 11
#define led2 10

void setup()
{
// Initialize the IO and ISR
vw_setup(2000); // Bits per sec

Serial.begin (9600); //this for hc-204
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
pinMode(led, OUTPUT);
pinMode(led2, OUTPUT);
}

void loop()

{ //for getting the distance
long duration, distance;
char message;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;
message=distance;
send(message); // for sending the distance
delay(1000);
}

void send (char *message) //function to send message
{
vw_send((uint8_t *)message, strlen(message));
vw_wait_tx(); // Wait until the whole message is gone
}

How do I get the program to work?

char message;

That will hold ONE digit/letter.

message=distance;

That does NOT make a string out of distance.

send(message);                   // for sending the distance

Really? I'd never have guessed.

void send (char *message)     //function to send message

Really? I'd never have guessed.

The function expects a string - a NULL terminated ARRAY of chars, not a single char.

A few minutes searching the forum would have given you dozens of options.

sprintf() is the easiest, though it bulks up the code more than absolutely necessary. If that doesn't matter (as in your case), go for it.
