5. Add the codes.
Enter the programming environment. First of all, declare “void
SendToUSB(CString cmd)” and “unsigned char* Read_USB( void )” in header file,
then add the following codes:
//send setting command
void SendToUSB(CString cmd)
{
int temp,j;
CString cmdstr;
cmdstr = cmd;
unsigned char * strInput;
//recall the GetTMCDeviceNum and WriteUSB function from
RigolTMCUsb_UI.dll
HMODULE module = LoadLibrary("RigolTMCUsb_UI.dll");
typedef bool (CALLBACK* pWrite)(unsigned long, unsigned char,unsigned
char,unsigned long,unsigned char*);
typedef int (CALLBACK* pGetDeviceNum)();
temp = cmdstr.GetLength();
strInput = (unsigned char*)cmdstr.GetBuffer(10);
if(module)
{
pGetDeviceNum GetDevice =
(pGetDeviceNum)GetProcAddress(module,"GetTMCDeviceNum");
pWrite Write = (pWrite)GetProcAddress(module,"WriteUSB");
j = GetDevice();
if( j > 0 )
{
//send a command to the oscilloscope
//the definition of interface has been mentioned in “Rigolusb.h”
