Question

I want to show a open dialog for the user, where the user can select only the files from the removable disks in the system. I am using the below code. But i need to get the Guid of removable disk to open the dialog.

Tell me how…

System.Windows.Forms.OpenFileDialog dls = new System.Windows.Forms.OpenFileDialog();
dls.CustomPlaces.Clear();
foreach (DriveInfo Drive in ListDrives)
{
    if (Drive.DriveType == DriveType.Removable)
    {
        dls.CustomPlaces.Add(-----Guid of Drive------);
    }
    dls.ShowDialog();
}

I don’t have an answer how to get the Guids for the removable drives, however setting the CustomPlaces collection will not restrict your users from selecting anything but the folders in the collection, they will simply show up as shortcuts on the left of the open file dialog, and then only if you have the AutoUpgradeEnabled proptery set to true and your users are running Windows Vista or higher.

Although, to finish off where you started, use the DriveInfo.Name to create a new entry in your custom places:

System.Windows.Forms.OpenFileDialog dls = new System.Windows.Forms.OpenFileDialog();
dls.CustomPlaces.Clear();
foreach (DriveInfo Drive in ListDrives)
{
    if (Drive.DriveType == DriveType.Removable)
    {
        dls.CustomPlaces.Add(Drive.Name);
    }
    dls.ShowDialog();
}
