Hallo,
Problem mit dem o.g. Dialog:
Wie kriege ich die Filter definiert? (*.*, *.dat, …)
Wie kriege ich ihn dazu, die auch anzuwenden?
Wie kriege ich raus, welcher Knopf gedrückt wurde?
Da gibbets unendlich viele Properties, aber die funktionieren alle nicht so recht!
Danke,
Kristian
Hallo vielleicht hilft dir diese API-Implementation
