Creating a loop? Need some guidance!
 

Hello, I have downloaded some coding off the internet and modified it to suit my needs. It opens and closes the CD drive ONCE. And I would like to make it do so an infinate amount of times.


#include "windows.h"
#include "winioctl.h"
#include <string>
using std::string;


int main(int argc, char* argv[])
{

string sdrive("\\\\.\\e:"); //replace 'g' by the drive letter of the cdrom

HANDLE hcd = CreateFile(sdrive.c_str(),
GENERIC_READ,
FILE_SHARE_READ,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_READONLY,
NULL);

if (hcd == INVALID_HANDLE_VALUE)
printf("Could not open drive g:\\\n");

DWORD d = 0;
DeviceIoControl(hcd, IOCTL_STORAGE_EJECT_MEDIA, NULL, 0, NULL, 0,
&d, NULL);
DeviceIoControl(hcd, IOCTL_STORAGE_LOAD_MEDIA, NULL, 0, NULL, 0,
&d, NULL);
CloseHandle(hcd);

return 0;

}


Thank you all!

This is the third time I'm going to tell you to : PLEASE USE CODE tags

You need a loop around the two DeviceIoControl() lines like :

while(1){  DeviceIoControl things }

DWORD d = 0;

This line is useless

Sorry, I don't really know where to put this and how to declare it. Could you maybe show me exactly what to do?

Thanks

As I said:

while(1)

{

DeviceIoControl(hcd, IOCTL_STORAGE_EJECT_MEDIA, NULL, 0, NULL, 0,

&d, NULL);

DeviceIoControl(hcd, IOCTL_STORAGE_LOAD_MEDIA, NULL, 0, NULL, 0,

&d, NULL);

}

I get an error message that &d is undeclared, can you help?

Thanks

is this line still there?

DWORD d = 0;
