Open a file which automatically opens addtional 2 files

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 .

The other files can't be automatically opened, but it's easy to do what you want nevertheless.

Once the file dialog returns with the file name of the *.bmp file, just create two more strings, copied from the *.bmp file name string, but with the bmp replaced with dat and wav respectively.

e.g. something like (and I haven't tested this)
CommonDialog.FileName = ""
CommonDialog.Filter = "bmp (*.bmp)|*.bmp"
CommonDialog.ShowOpen
If CommonDialog.FileName = "" then Exit Sub
bitmapName = CommonDialog.FileName
waveName = left(bitmapName, InStr(bitmapName, ".")) & "wav"
dataName = left(bitmapName, InStr(bitmapName, ".")) & "dat"

Then open each of the three files in the normal way.
