Please show the string Command is receiving, the string you're working
with, and the code that uses the string.

Don't be so sure what is and isn't obvious, you might find a simple
typo wreaks havok in your code. For example, is Option Explicit the
first line in all your code modules? If not, make it so and try again.

If your program works when you hard code a string, but not when
you use the Command function, then something is wrong with your
handling of the Command function. Are you sure you are getting only
one file name? Have you double checked your ability to remove the
quotes on either end? Do you test to be sure what you end up with is
a valid file name? etc.. etc....

Programs don't fall into place, you have to put every letter exactly in
place for the thing to run. Likewise you should check your data to
be sure it is exactly what you expect all through the process.

Thanks all for the help.

First let me thank everyone for their assistance. Greatly appreciated.

For what I thought would take me an hour to write a simple program to
substitute the
current folder on my system for the embedded folder associated with a image
on
a downloaded web page has turned into a good reminder of "Murray's Law".

That said, it appears I may be dealing with two issues.

1) Getting a file string from Explorer from VB using the Command line
function where the file name contains spaces.

In this instance stripping the quotes from the beginning and end of the
file name that is returned on the
command line "appears" (juries still out) to resolve the issue.
This was determined by hard coding the directory then sending it to a label
as well as sending the string returned from command to another label.

Further internet research seems to confirm this fact.


[CODE]

strExplorerPath = Command$()

'The Command Line returns a string with quotes on
'beginning and end. These need to be removed otherwise
'fails as string
'Strip right quote character
If Right$(strExplorerPath, 1) = Chr$(34) Then
strExplorerPath = Left$(strExplorerPath, Len(strExplorerPath) - 1)
End If

'Strip left quote character
If Left$(strExplorerPath, 1) = Chr$(34) Then
strExplorerPath = Right$(strExplorerPath, Len(strExplorerPath) - 1)
End If

[/CODE]

2) The second issue:
I just happened to download a second web page to use for testing
that contains some type of scheme to keep a search/replace program from
altering the
htm file (my luck).
So I need to spend some time figuring out what was done and how to beat
it as I'm sure
it may be used more than just the web page I picked.

Consequently, I am closing this thread.
