hi dear,
i need to develop custom openfile dialog box with preview in VB.NET like shown in attachment... plz help me...

many thanks,

The best way to get started on this, is to make the dialog box as a form of your own... so in your project add a new form, and design it to look like that (with the controls and drop-downs where they go, and the picture box). Then start working on the code for it. The OpenFileDialog control won't support what you want to do, neither will the API Call. Let me know if you find a solution that I've overlooked.
