Is there something wrong with my open file dialog filter?

[Shammikit]

so i have this filter setup for filtering out flv and mp4 files in my open file dialog but it doesnt seem to be working. when i go to my directory with flv and mp4 files they dont show up. what could be the reason. is my filter incorrect? 

openFileDialog1.Filter = "mp4 Files (*.mp4)|*.MP4 | flv files(*.flv)|*.flv ";

Update: i have tried *.* on the filter as well even that doesnt work!

im not a coding expert at all. I dont even code, but shouldnt the ".MP4" be lowercase like the other one? sorry if i said something stupid. lol

i previously had it lowercase and i wrote it in uppercase to see if that works. but no. even the flv files dont show up.

The problem is the whitespace in the extension parts of the string

openFileDialog1.Filter = "mp4 Files (*.mp4)|*.MP4 | flv files(*.flv)|*.flv ";
                                             here^                and here^

You need to remove the whitespace like so

openFileDialog1.Filter = "mp4 Files (*.mp4)|*.MP4| flv files(*.flv)|*.flv";

Note that the description portion of the filter string can have spaces, which is the reason that "mp4 Files (*.mp4)" and "flv files(*.flv)" are allowed. It's just the extension portion of the filter string that can't have spaces.
