What security pop-up usb mobile devices-CodePudding

Had forgot it, recently found jinshan guards have a such assistant safe to pop up, also can restore, and reminded me of this feature.

In c + + builder how to implement.

In 7th floor in this way, can perform successfully, but U disk has not removed, there is no response.

The complete code is as follows:

 

#include  
#include  
#include  
#include  


Void __fastcall TForm1: : btn1Click (TObject * Sender) 
{
HANDLE hDevice;//handle to the drive to be examined 
BOOL bResult;//the results flag 
BOOL bRet. 
DWORD junk;//the discard the results 
DWORD dwError; 
//Open the volume 
HDevice=CreateFile (" \ \ \ \. \ \ I: ",//drive to open 
GENERIC_READ | GENERIC_WRITE, 
FILE_SHARE_READ | FILE_SHARE_WRITE,//share mode 
NULL,//the default security attributes 
OPEN_EXISTING,//disposition 
0,//the file attributes 
NULL);//don 't copy any file' s attributes 

If (hDevice==INVALID_HANDLE_VALUE)//can 't open the drive 
{
DwError=GetLastError (); 
ShowMessage (" to create the file!" ); 
return ; 
} 

//Dismount on the volume 
BResult=DeviceIoControl (
HDevice,//handle to volume 
FSCTL_DISMOUNT_VOLUME,//dwIoControlCode tells them 
NULL,//lpInBuffer 
0,//nInBufferSize 
NULL,//lpOutBuffer 
0,//nOutBufferSize 
& Junk,//the discard the count of bytes returned 
(LPOVERLAPPED) NULL);//synchronous I/O 
if (! BResult)//IOCTL failed 
{
DwError=GetLastError (); 
ShowMessage (" Fail to dismount on the volume!" ); 
} 

//Close the volume handle 
BRet=CloseHandle (hDevice); 
if (! BRet) 
{
DwError=GetLastError (); 
ShowMessage (" Fail to close the handle!" ); 
} 
The else 
{
ShowMessage (" success!" ); 
} 
}

In addition, my U disk drive is "I", this is true, the back of the "success!" I added, have prompted the execution of the.

CodePudding user response:

Don't have U disk, evening go back and help you debug it.

CodePudding user response:

refer to 7th floor ccrun response:

don't have U disk, night back to help you debug it.

Well, thank you for your demon elder brother.

CodePudding user response:

Then top up...

CodePudding user response:

A novice with o! There is the source of that don't know how to compile, always make mistakes, novice forgive me

Drain, just found this post I'd put a dove, I need the code? Please pick one,

Microsoft mobile devices provide the security removed runtime does the equipment removed, just my computer mobile operators and mobile desktop tray equipment identifiers are not removed, so feel like code is invalid,

Or there is a problem, when U disk file has been opened, is actually remove failure, but still show success, where can judge, and give the corresponding prompt information, is occupied by which application.

CodePudding user response:

My test is, if open U disk root directory, perform the root window automatically shut down after, my computer U disk drive double-click to open has no content, prompt inserted U disk, but the tray icon is still there,

my test is that if U disk open the root directory, perform the root window automatically shut down after, my computer U disk drive double-click to open has no content, prompt inserted U disk, but the tray icon is still there,

If U dish in the file is opened, is what I said above.

CodePudding user response:

Can iterate through all the first open the resources of the usb drive and close it again perform removed

CodePudding user response:

Or wait for old demon from view to inspect the code

CodePudding user response:

refer to the 18th floor sololie response:

Well, jinshan guards U disk assistant is like this, you will be prompted by any application, and then have a occupied the list of files to choose whether or not to shut down.

CodePudding user response:

Then traverse the open close U disk resources, perform removed, then SHChangeNotify, the rhythm is right,

CodePudding user response:

refer to 21st floor sololie response:

then traverse open shut U disk resources, perform removed, then SHChangeNotify, is this rhythm,

It is best to prompt, let users keep, shut down.

CodePudding user response:

This,,,, you are all already know how to do,

Old demon has come, estimates that in the test code to you for repair to share.
