Hello everyone,

I am wondering what is the function of .suo file? If I want to share source codes with other people, for example, using CVS or something similar, does this file mandatory to check-in? Do other people need this file to make a same build and setup the same working environment as mine?

thanks in advance,
George

No, you don't need to share this file. The only files that you need to save into CVS are the source files (.cpp and .h), the solution file (.sln) and the project files (.vcproj, one for each project in your solution). This is for VS2005, for VC6 the project and 'solution' files are different (.dsw and .dsp) and for VS2003, I don't know Wink | ;)

Thanks Cédric,

What is the function of .suo file?

It contains information about the user settings. For example, which files are opened, which nodes in the 'explorer' window are expanded, the position of the breakpoints, ...
So, it is very user specific and doesn't need to be saved in CVS (and it shouldn't, because I think it is quite annoying to loose all this information each time).

if you are run your Java app. with CreateProcess(Ex) you can use WaitForSingleObject().
other variant is in scanning processes list for looking your java app.

But the sample is already there in the link I provide.

The cd drive can be ejected and inserted using the DeviceIoControl() function. For eg if you want to eject the drive the below code will do

DeviceIoControl(
(HANDLE) hDevice, // handle to device
IOCTL_STORAGE_EJECT_MEDIA, // dwIoControlCode
NULL, // lpInBuffer
0, // nInBufferSize
NULL, // lpOutBuffer
0, // nOutBufferSize
(LPDWORD) lpBytesReturned, // number of bytes returned
(LPOVERLAPPED) lpOverlapped // OVERLAPPED structure
);

And for inserting change the flag to IOCTL_STORAGE_LOAD_MEDIA

DWORD bytesreturned;

Now you are passing an invalid value as hDevice.

see the below code in the above link.

HANDLE OpenVolume(TCHAR cDriveLetter)<br />
   {<br />
       HANDLE hVolume;<br />
       UINT uDriveType;<br />
       TCHAR szVolumeName[8];<br />
       TCHAR szRootName[5];<br />
       DWORD dwAccessFlags;<br />
<br />
       wsprintf(szRootName, szRootFormat, cDriveLetter);<br />
<br />
       uDriveType = GetDriveType(szRootName);<br />
       switch(uDriveType) {<br />
       case DRIVE_REMOVABLE:<br />
           dwAccessFlags = GENERIC_READ | GENERIC_WRITE;<br />
           break;<br />
       case DRIVE_CDROM:<br />
           dwAccessFlags = GENERIC_READ;<br />
           break;<br />
       default:<br />
           _tprintf(TEXT("Cannot eject.  Drive type is incorrect.\n"));<br />
           return INVALID_HANDLE_VALUE;<br />
       }<br />
<br />
       wsprintf(szVolumeName, szVolumeFormat, cDriveLetter);<br />
<br />
       hVolume = CreateFile(   szVolumeName,<br />
                               dwAccessFlags,<br />
                               FILE_SHARE_READ | FILE_SHARE_WRITE,<br />
                               NULL,<br />
                               OPEN_EXISTING,<br />
                               0,<br />
                               NULL );<br />
       if (hVolume == INVALID_HANDLE_VALUE)<br />
           ReportError(TEXT("CreateFile"));<br />
<br />
       return hVolume;<br />
   }

If you specify the drive letter of the drive, te above function will return a handle pass that handle to the DeviceIoControl() function. like

HANDLE hVolume = OpenVolume( "E:" );<br />
OpenVolume( hVolume, IOCTL_STORAGE_EJECT_MEDIA, NULL, 0, NULL, 0, &bytesreturned, NULL );
