How to display a list of directories and files 1

[vatawna]

Hello,

Does anybody know how to populate the combo box control with directories and files starting from the top level "My Computer"? In other words, the combo box control actually shows a tree of directories and files when it is dropped-down.

Thanks,
Mimi

Have a look at the System.IO namespace

Hope this helps.

You have System.Management workspace to accompplish this task.
To get the Desktop and the logical drivers:
System.Management.ManagementObject mgtObject;
System.Management.ManagementObjectSearcher oSearch=new System.Management.ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk");
Now loop each drive held in the oSearcher object and place each drive in mgtObject:
foreach mgtObject in oSearcher.Get()
{
int driverImage=-1;
string sDriveLetter = mgtObject.Properties("DeviceID").Value;
string sDriveDesc = sDriveLetter + mgtObject.Propoerties("Description").Value;
string sVolumeName = mgtObject.Properties("VolumeName").Value;
//get the image for disk
switch(driverImage=Convert.ToInt16(mgtObject.Properties"DriveType").Value)
{
case 6: // Unknown
case 3: // Compact disk
case 4: // Network disk
case 2: // Local disk
driverImage=2;
case 1: // Removable
case 6: // No root directory
case 0: // RAM disk
}
// Check network connection
// if image drive is 4 and mgtObject.Properties("Size").Value is null then
driverImage =5 (Network disconnected)

}
Retrive the images of each drive using Bitmap object and draw the tree in the combobox with these drivers elements(letter, image and description):
+image Desktop
+ image C:\Local Disk Doppo.
+ image D:\ DVD/CD RW-Drive
+ image E:\ Removable Disk
Now iterate through each availabale drive and retrive a list of folders and so on files using System.IO.Directory.
