-->>The name of Common Dialog is Folder...
-->>But now as I've the Open Button when the Browse Windows Show up,I was wondering how can I...
-->>Open the Selected File when User Click the Open Button and the File to open using its Default -->>application...
-->>My Code on the Module is this:

Public Sub User_Folder(Users As CommonDialog)
'******************************************************************'
'*       COMMON PROCEDURE TO ACCESS USER FOLDER IN A SYSTEM       *'
'******************************************************************'


With Users
        .DialogTitle = "TITLE OF MY BROWSE WINDOW:"
        .InitDir = GetAppPath() & "MY INITIAL FORLDER:"
        .Filter = "(*.bmp; *.jpg; *. gif; *.pcx; *.mp3;*.pcx;)| *.bmp; *.jpg; *.gif; *.pcx; *.mp3;*.pcx;|" & _
                  "(*.wma; *.wav; *.mpg; *.avi; *.VOB;*.png;)|*.wma; *.wav; *.mpg; *.avi; *.VOB;*.png;|" & _
                  "(*.mdb; *.txt; *.doc; *.xlsx; *.pptx;*.psd;)|*.mdb; *.txt; *.doc; *.xlsx; *.pptx;*.psd;|" & _

                  "(*.All files)|*.*|"
        .ShowOpen
End With

End Sub

-->>On the Form's Command Button I call the Procedure as this:

Private Sub Browse_Folder_Click()
User_Folder Folder
End Sub

-->>Any Suggestions? Thanks...

Not sure what you need Bile...

After the user found the file (via your code above), you want to open say a word document, picture etc? Seems that you will be making use of the shell command then.

For word etc, a little different. Let me know if you will be opening ms office files at all.

-->>Thats Exactly what I mean Andre,but as You can See that I alredy have a Button...
-->>named Open on the browsing window,thus after the User has found and selected...
-->>a file its name shows up in a File name Field of the Browse window what remains is...
-->>just to open it by its default Application when the Button is pressed...
-->>Now how will I use the Shell Command to pic up the default Application for a File?..
-->>For Example I wanted to Open Calculator and I used the following code:

Public WshShell As Object

Dim Calculator As Double
Calculator = Shell("C:\WINDOWS\System32\calc.exe", vbNormalFocus)

-->>It worked fine and I can open the Calculator,so on the case above does it mean that...
-->>First I have to Check for file extension so that I can eccess the required...
-->>apllication to open the file or? Becouse as I can see it looks like I'll have to do...
-->>lots of branching based on My Filtering criteria...
-->>I hope now I've tried to explain Myself?...

Are you trying to tell us that you do not understand how to use the CommonDialog to retrieve the selected file?

If so, take a look at this link: http://www.developerfusion.com/article/11/common-dialog-control/3/

Bile 10 Newbie Poster · Answer 5 · 2013-02-20T16:03:40+00:00

-->>Nop,thats NOT exactly what I mean I can use the CommonDialog to retrieve the selected file just fine
-->>and I hope that if You can follow the code above can assist Me to do so just by adding Filename...
-->>Or File Title than get it in what ever the control I have prepared for suc as Text box.
-->>But I mean after I have the File Selected from the Dialog that appears,may be I should say ...
-->>"HOW CAN I RUN IT BY ITS DEFAULT SOFTWARE BASED ON ITS TYPE AND EXTENSION"?...
-->>Say its an MP3 Audio Music File to be Rub may be by VLC or WMPlayer once the I press the Open...
-->>Button on the Dialog (The File Should Automatic Pic its default Software and Run) so that I can...
-->>listen to a Selected Music...
-->>Or is it NECESSARY that I get its name or title first in My application and have another...
-->>Button to Run it?

AndreRet 526 Senior Poster · Answer 6 · 2013-02-21T08:06:09+00:00

If I read this correctly, you want to read what type of file extension the selection have and then open that file with its own application, i.e. .doc = ms word, .xls = ms excel etc...

Get the users selection into a variable say strFile, use InStr to read the parts after the . (dot) and then use shell to open accordingly...
