My program call a batch file at runtime.
The batch file like:
ren *.abc *.edf
The question is
After I call the batch file, I found the *.abc files didn't renamed to *.edf files. The *.abc are in the D:\Delphi dir.
I used to be able to see the DOS window after called and executed the batch file, but now I could not to see it because it auto closed after running the batch file.
