I suppose Mark's first sentence wasn't 100% clear. People who do not have a good grasp of the API would not know where to start, thus no code will be shown.

In this case, the question was fairly easy. I even took the code from a previous post I located via POFFS:

Silly me.

I mistook "My APP looks for it and finds it " as "My APP looks for it and finds it."

Guess I should have studied the posted code more carefully, huh?

[Kev Peel]

I took \\usbdrive\myfile.dat to mean a placeholder.

This code will return all drives present. Removable drives such as Floppy, CD-ROM/DVD or USB sticks are reported as DRIVE_REMOVABLE. I would check for all drives of this type but skip drive A:\, this would be acceptable in most cases.

#Compile Exe
#Dim All
#Include "win32api.inc"
Function PBMain
 
  Local i As Long
  Local sDrives As String
  Local szType As Asciiz * 128
 
  sDrives = String$(GetLogicalDriveStrings(0, ByVal %Null), $Nul)
  GetLogicalDriveStrings Len(sDrives), ByVal StrPtr(sDrives)
  sDrives = RTrim$(sDrives, $Nul)
 
  For i = 1 To ParseCount(sDrives, $Nul)
      Select Case Const GetDriveType(Parse$(sDrives, $Nul, i))
             Case %DRIVE_UNKNOWN: szType = "DRIVE_UNKNOWN"
             Case %DRIVE_NO_ROOT_DIR: szType = "DRIVE_NO_ROOT_DIR"
             Case %DRIVE_REMOVABLE: szType = "DRIVE_REMOVABLE"
             Case %DRIVE_FIXED: szType = "DRIVE_FIXED"
             Case %DRIVE_REMOTE: szType = "DRIVE_REMOTE"
             Case %DRIVE_CDROM: szType = "DRIVE_CDROM"
             Case %DRIVE_RAMDISK: szType = "DRIVE_RAMDISK"
             Case Else: szType = "Unknown type"
      End Select
      MsgBox Parse$(sDrives, $Nul, i) + $CrLf + "Drive Type: " + szType, , "Drive Number #" + Format$(i)
  Next i
 
End Function

You said you found "\\usbdrive" !!!

Try that in your OPEN - just like I typed it!!!

[Mark A Nelson]

How do I know what drive to use?

[Michael Mattias]

What happened when you tried...

open "\\usbDrive\myfile.dat" FOR INPUT AS #6742

...????

Then again, if your user has to insert the thing, he or she must be there and you could prompt them for a drive letter.

What I would like to do is when a users put in a USB Drive. My APP looks for it and finds it , Search \\usbdrive\myfile.dat. But I am missing the boat here. I never know what drive letter it will be? So can't put f:\ or h:\ cause I never know what letter it will be..
