Visual Studio257
I'm writing an application where then end-user will want to view and print

(not edit) TIFF and JPEG images. For now, I simply use the

System.Diagnostics.Process.Start method to open the desired image with the

application currently associated with that file type.



However, sometimes the wrong application is associated with a file type.

For example, Microsoft Office Picture Manager will only display the first

page of a multi-page TIFF image with no way to view the additional pages

(that I know of). Also, I suspect it may be possible that some older

machines running Windows ME or Windows 98 may not have an application

associated with TIFF images.



So, I'd like to check on the current application associated with TIFF

images. What is the best way to go about doing that?



Any advice or suggestions are greatly appreciated.



Thanks,



Carl

You can use the FindExecutable API function call:



Declare Function FindExecutable Lib "shell32.dll" Alias "FindExecutableA" (ByVal lpFile As

String, _

ByVal lpDirectory As

String, _

ByVal lpResult As

System.Text.StringBuilder) As Int32



Function FindAssociatedApp(ByVal FullFilePath As String) As String



Dim FileDir As String



Dim FileExecutablePath As New System.Text.StringBuilder(255)



If FindExecutable(FullFilePath, FileDir, FileExecutablePath)>32 Then

Return (FileExecutablePath.ToString)

End If



End Function





FileExecutablePath = FindAssociatedApp("e:\My Documents\book1.xls")
