I am using the following statement in my test application:

OpenFileDialog1.Filter = "Bitmaps (*.bmp) | *.bmp | JPG Pics (*.jpg) |
*.jpg"
It shows me two choices (in the drop download) when the dialog is opened.
One ofr BMP files and other for JPG.  when I select .BMP selection it does
not show any files in the current folder. I only see the sub-folders but not
the bmp files in it. On the other hand when jpg choice is selected, I cann
all the jpg files.

PS: If I manually type in *.bmp in the gialog, then I can see all the bmp
files.

Any ideas?

Thank you.

Remove (trailing) spaces, at least in the extension parts:
OpenFileDialog1.Filter = "Bitmaps (*.bmp)|*.bmp|JPG Pics (*.jpg)|*.jpg"

It works with *.jpg because there's no trailing space character (" *.jpg"
vs. " *.bmp ")
