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

Well... I actually found the answer for that.  Jason's suggestion was great but there is an easier way to do that.  One can use the shell function to do that as shown below.

  Shell ("notepad.exe c:/temp/Your_file.txt",  vbNormalFocus)

Basically, after the notepad.exe, programmer should give the path to that particular file and then the file name offcourse.

Thanks for your help Jason.
