Currently for my application, I am printing the output in a text file.  My intention is when the user clicks on the print command button, it should open up Notepad with that particular text file.  I tried the shell function, but that only opens up notepad.  How do I open that particular text file.  I suppose I have to do this with OLE.  If anybody can help me out with this, I would really appreciate it.
Thanks

Hi Vasant,
You can use the following code to do this, just paste it into the code section of your form;

***Start Of Code***
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
       (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, _
       ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd _
       As Long) As Long

Private Declare Function GetDesktopWindow Lib "user32" () As Long
Private Const SW_SHOWNORMAL = 1
 

     'Description:How do I launch a file in its associated program?

Function StartDoc(DocName As String) As Long

       Dim Scr_hDC As Long
       Scr_hDC = GetDesktopWindow()
       StartDoc = ShellExecute(Scr_hDC, "Open", DocName, "", "C:\", SW_SHOWNORMAL)
End Function
 
Private Sub Form_Click()
       Dim r As Long
       r = StartDoc("c:\your_text_file.txt")
       Debug.Print "Return code from Startdoc: "; r
End Sub
***End Of Code***

I hope this helps!

Sincerely,
Jason
