Paths containing spaces

When using the mciSendString with a pathing variable, it doesn't like the spaces in the path.  For example:
MyPath = "c:\Program Files\filename.avi" confuses the command; whereas MyPath = "c:\Program_Files\filename.avi" is okay.  Any way around this?  I cannot alway control the directory name the user creates.

Try """c:\Program Files\filename.avi"""

You need to include quotes in the string, and by placing two quotes together, you tell VB to use a quote as a character and not a delimiter.

Thanks for the reply...but NG. Here's what I have:

CmdStr = ("open " & AVIFileName & " Type AVIVideo alias Animation parent " _
           & LTrim$(Str$(frmAVI.hwnd)) + " style " + LTrim$(Str$(WS_CHILD)))

Where AVIFileName = F:\tgsc\KeySpan\RD Project Tracker\search.avi

When I send the CmsStr the mciSendString sees the spaces in the path and expects a parameter.  What can one do?

Strip the spaces from the path string. This might cause problems for paths that are supposed to include spaces (i.e. C:\Program Files\Office97).


This function will remove all spaces from a string. Use it to remove spaces from OldPath using the statement.

NewPath = NoSpace(OldPath)

Private Function NoSpace(ByVal PathString) As String
Dim i As Integer
Dim FirstPart As String
Dim SecondPart As String

   PathString = Trim$(PathString) ' get rid of leading/trailing spaces

Do
   i = InStr(PathString, " ")  ' find the first space
   If i = 0 Then Exit Do ' no more spaces found
   FirstPart = Left$(PathString, i - 1)
   SecondPart = Right$(PathString, Len(PathString) - i)
   PathString = FirstPart & SecondPart
Loop
NoSpace = PathString
End Function



This second function only removes those spaces that are next to the backslash characters, and leaves all the others in place. A similar method could eliminate spaces next to the colon, or the period characters.

Private Function NoSpace(ByVal PathString) As String
Dim i As Integer
Dim FirstPart As String
Dim SecondPart As String

   PathString = Trim$(PathString) ' get rid of leading/trailing spaces

Do
   i = InStr(PathString, " \")  ' space before slash
   If i = 0 Then Exit Do ' no more spaces found
   FirstPart = Left$(PathString, i - 1)
   SecondPart = Right$(PathString, Len(PathString) - i)
   PathString = FirstPart & SecondPart
Loop

Do
   i = InStr(PathString, "\ ")  ' space after slash
   If i = 0 Then Exit Do ' no more spaces found
   FirstPart = Left$(PathString, i)
   SecondPart = Right$(PathString, Len(PathString) - i - 1)
   PathString = FirstPart & SecondPart
Loop
NoSpace = PathString
End Function


Finally, this function will replace any spaces in the path with the underscore character:


Private Function NoSpace(ByVal PathString) As String
Dim i As Integer
Dim char As String

   PathString = Trim$(PathString) ' get rid of leading/trailing spaces

For i = 1 to Len(PathString)
   char = Mid$(PathString, i, 1)
   If char = " " Then Mid$(PathString, i, 1) = "_"
Next i

NoSpace = PathString
End Function

hddp666: his sample include "program files" so why answer this question.
BWATERS:
Use the short filename of the file. Here is a sample of how to convert the long filename to a short filename

Private Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal cchBuffer As Long) As Long
Private Sub Command1_Click()
    Dim str As String
    str = String$(260, 0)
    Call GetShortPathName("c:\my documents\uitnodiging.ppt", str, 255)
    MsgBox str
End Sub
