You'll have to convert it manually, for example (untested):


bool __fastcall HexToBinary(AnsiString Hex, AnsiString &Binary)
{
    static char* HexBinaryLookup[] = {"0000", "0001", "0010", "0011",
                                      "0100", "0101", "0110", "0111",
                                      "1000", "1001", "1010", "1011",
                                      "1100", "1101", "1110", "1111"};

    Binary = "";
    if( Hex.SubString(1, 2).AnsiCompareIC("0x") == 0 )
        Hex.Delete(1, 2);

    for(int i = 1; i <= Hex.Length(); ++i)
    {
        char c = Hex[i] & ~20;    // simple way to force uppercase
        int index = -1;
        if( (c >= '0') && (c <= '9') )
            index = (c - '0');
        else if( (c >= 'A') && (c <= 'F' ) )
            index = (c - 'A' + 10);
        else
            return false;    // invalid input

        Binary += HexBinaryLookup[index];
    }
    return !Binary.IsEmpty();
}

Then you can do something like this:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    AnsiString binary;

    if( HexToBinary(Edit1->Text, binary) )
        Edit2->Text = binary;
    else
        ShowMessage("Please enter a valid hex value!");
}
