vb 2010 OpenFileDialog show specified file

I will try to make this clear, i have an application that opens the file location of a running process, however when the process is located in a large folder like system32 it just opens at the first item,

What i really want is for the specified .exe to be highlighted or 开发者_开发问答in focus within the dialog window, is there a way to filter or use the built in search box in the window programaticaly??

Many thanks

Set the FileName property to the file you want before showing the dialog.
