Use ShellExecute to sidestep certain linking problems
Some programs don't cooperate with PPT when you link to their files. The first release of Adobe Reader 7 is one example. When you set an Other File action setting in PowerPoint to open a PDF and click the link in slide show view, either nothing happens or you see a brief blink of Reader, which then disappears. And then nothing happens. (Note: this problem has been fixed in the 7.0.1 update to Reader).
Either way, you don't see the PDF you were expecting to view.
If you plan to run your presentation in PowerPoint, try the following VBA macro as a possible solution.
This won't work in the free PowerPoint viewers, and it won't work if your Macro security settings are on High.
To use it:
- Assign a shape an Other File action setting and choose the file.
- With the shape selected, run the AssignTag macro below. That will tag the shape with the name of the file to be launched, then assign the shape's action setting to be Run Macro: ShellExShape
Now put the file in SlideShow view and click the shape to see if it launches the document.
If it works, send a virtualkiss, money, whatever to Charles Wannall, whose post on the Adobe newsgroup suggested this workaround.
Option Explicit Const SW_SHOWNORMAL As Long = 1 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 Public Sub AssignTag() ' Select a shape and run me: With ActiveWindow.Selection.ShapeRange(1) If .ActionSettings(ppMouseClick).Hyperlink.Address <> "" Then Call .Tags.Add("FILENAME", .ActionSettings(ppMouseClick).Hyperlink.Address) .ActionSettings(ppMouseClick).Run = "ShellExShape" End If End With End Sub Public Sub ShellExShape(oSh As Shape) ' Assign this macro as the shape's action setting Dim sFileName As String On Error GoTo ErrorHandler ' Get the name of the file assigned to the shape as a tag sFileName = oSh.Tags("FILENAME") ' ShellExecute the file if one's listed If Len(sFileName) > 0 Then Call ShellExecute(0, "Open", sFileName, "", "C:\", SW_SHOWNORMAL) End If NormalExit: Exit Sub ErrorHandler: Resume NormalExit End Sub
