Suppose I want to open a bmp file using a file dialog . In addition to opening this bmp file I also want to open another 2 files : .dat & .wav files . These 3 files are of same name but just different types. I am trying to say is that by opening the bmp file using the file dialog , the other 2 files are also automatically opened with the bmp file. I need a file dialog because I have alot of this bmp files with the .dat & .wav files. For the .dat files , i already have procedures opening it . I need to know how can i open the bmp file using a dialog & by doing so , the .dat & .wav files of the same name as the bmp file can also automatically opened .
