Re: char to hexidecimal

You could always use something like this....ofcourse you need to adapt it

C++ Syntax (Toggle Plain Text)
#include <iostream>
#include <string>
#include <sstream>
 
using namespace std;
 
int main(void){
 
    ostringstream hello;
 
    hello << hex << (int)'A';
    cout << hello.str();
 
    cin.get();
    return 0;
}
#include <iostream>
#include <string>
#include <sstream>

using namespace std;

int main(void){
    
    ostringstream hello;
    
    hello << hex << (int)'A';
    cout << hello.str();
    
    cin.get();
    return 0;
}

Re: char to hexidecimal

what I want is something like this

C++ Syntax (Toggle Plain Text)
char buffer[10];
buffer[0] = 0x5F;
TextBox->Text = buffer[0];
char buffer[10];
buffer[0] = 0x5F;
TextBox->Text = buffer[0];

i need to cast or a function to convert or something that I dont know about to get the text box to display 0x5F or 5F. Thanks.
