Initialize OpenFileDialog

[barbara_dave@yahoo.com]

Hi, All,

I want to use the openfiledialog to open different extension files in
different directory( only one type files at one time). I set the
OpenFiledialog InitialDirector y and Filter property for ".dat" files at
first time, it works. When I try to use openfiledialog to set different
InitialDirector y an different Filter property for ".txt" files at
second time, I got frozen window. Even I added code to dispose
openfiledialog after using it, I still got frozen window. How to use
OpenFileDialog to open one type file in a directory and open another
type file in another directory next time?
Thinks a lot for your time and help!
