Import picture file ActiveX

[erez]

I need to add pictures to a certain slide. However the pictures file location , may change so I can't just write hard copy for the pictures location[FONT='Arial','sans-serif'].[/FONT]
Is there an ActiveX I can add to a form, that will enable the user to choose the file location[FONT='Arial','sans-serif']?[/FONT]
[FONT='Arial','sans-serif']I know such an ActiveX exists in vb6, but what about v.b.a, and more specifically in power-point , thought I assume such ActiveX is generic for all office applications[/FONT]
[FONT='Arial','sans-serif'][/FONT]
[FONT='Arial','sans-serif'][/FONT][FONT='Arial','sans-serif']Thanks in advance[/FONT]

The last two functions (testOpenDialog and testSaveDialog) show you how to call the 'Save' and 'Open' dialog functions. You will need to change the parameters (such as .Filter ) when you use them (I am using them to select a PowerPoint file)
