Hi,
I need a preview control to show files under MS Vista (windows form). I see, that their are some shell extension that I can use, and has write my own somple control for that. Have you a control that can make that or plan it in the future?
For Example:
PreviewControl pc;
.....
pc.ShowFile("file.txt");
....
pc.ShowFile("data.xls");
And if a shell extension is installed the control should show the file.
I thinks that a control like this dont exist!Each file type need a control/program to render it on printer/screen, in any OS.
You can use an UltraPrintPreviewDialog with an UltraPrintDocument control to render and preview the prtinting, but you need a control that is able to render the fileFormat.
Remember: the development of software is not as simple as using ;)
Good lucky
Under XP we use the com preview class from shimgvw.dll. Under vista we can use the shell extensions to make some previews. Look on

But I wan't a control that make this for me automaticaly when it run under Vista, Windows 2008, Windows 7 and the later versions...
I looked, but the article explain how use the existent preview handlers and how write your owns.
My opinion remain the same: if there is not a preview handler for a certain file type you need to write it yourself.
Good luck.
