Is the button visible for you. normally when you change the value in the .rc file the position of the control will change.

Why don't you use the resource editor for the purpose?

Why do you need to modify the .rc file?
Why not use the dialog editor to move the control?

GetVolumeInformation[^] returns the disk's volume name, which could well be what you want.

Thank you for the solution.

but This returns only the volume information.
it teturns the name of the volume not a friendly name of the device.

i checked with the above WINAPI function it just returns the volume name

for example: the device inserted is "Trances 4GB Removable..." but it shows the volume name "Jack"

if i am wrong sorry and i hope when we insert the removable device it mounds with the device partition. that is the reason While we use WM_DEVICE_CHANGE enables to track the device and even to get the friendly name using GUID

But i am very scared how to get the friendly name of the removable drive using the drive name.
i am trying...

thanks...

Bet you can get that using WMI.

I use WMI Explorer[^] to explore what information there is in the WMI database for my system. I just plugged in my flash drive, and it seems to have a 'friendly name' in the Caption property of its Win32_DiskDrive instance.

This VBScript (you can run it from the command-line with cscript filename.vbs) can be used to retrieve that - the C++ equivalent is straightforward, but long-winded.

Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
Set drives = objWMIService.ExecQuery("Select * FROM Win32_DiskDrive")
For Each drive in drives
 WScript.StdOut.WriteLine drive.caption
Next

Thanks a lot !

My actual requirement towards this issue is this:

I am logging the file activities in Win32 DLL with the following details Create/Copy/Delete/Move details in the USB Drive - done
Along with Removable Drive Friendly Name – doing

I am not much familiar with system side Activities.
I hope we can use the WMI in Win32 dll applications . I will try it out.
And If u have any idea on this help me out.

Thank you.

Yes, you can - it's just a set of COM interfaces and objects, so is callable from C++.

You need a recursive function to find the files within sub-folders.
Check if the dwFileAttributes is FILE_ATTRIBUTE_DIRECTORY and if it is, pass its name as the root folder and call the same function from within.

The function signature would be something like this.
int RecursiveFind(TCHAR* lpFileName, TCHAR* lpRootFolder);

FILE_ATTRIBUE_DIRECTORY is there but i m not getting,
Here is the scenario:

char defaultPath[256]="C:\\Program Files\\sample\\";
char filename[256]="abc.max";

WIN32_FIND_DATA FindData;
HANDLE hFind;
hFind = FindFirstFile( filename, &FindData );

m i using like this.But i m not getting.

You can use of FindFirstFile/FindNextFile in a loop.

With MFC, use something like this:

void EnumFilesRecursive()
{
  CFileFind ff;
  BOOL bWorking = ff.FindFile("d:\\*.*");

  while (bWorking == TRUE)
  {
    bWorking = ff.FindNextFile();
    if (ff.IsDirectory())
    {
      if (ff.IsDots())
        continue;
      
      EnumFilesRecursive(ff.GetFilePath());
    }
    else
    {
      //call "ff.GetFilePath()" to get the file names
    }
  }

  return;
}

Using ADO ,records could be deleted using Delete(adAffectCurrent) or SQL queries.
Which one is more feasible and faster to process ? Blush | :O

As CPallini suggested - benchmarking...

The other factor to consider is this - which is simpler for you? - teh less time and effort you (have to) put in, the more likely the code is correct, and the more time you've got to do other stuff that matters!

Just adding to Carlo and Stuart's replies,

Usually if something is neatly wrapped up into a class and methods are exposed to you, it would come with a lot of conveniences like ease of use, error checking, etc., (most importantly prevents you from shooting your own foot). On any normal day, this must be a reasonable trade-off with the performance overhead that would impose (should take very little time more than the code what you might write - if written well).

I'd personally go with an existing class and use its methods, but that again depends on the requirements.

You may use ClipCursor()[^] to lock the mouse cursor within a specific rectangle.
