Hi Danny. Thanks for your reply. I am working on this again (after a nice
little vacation :) and have a/some questions.
I need to copy a PRC from ROM to RAM. I have a method to detect that the
PRC is in ROM. I wrote a routine to use ExgDBWrite to write the PRC file
out from ROM into a stream. Then it takes the stream and uses ExgDBRead to
put it back into RAM. However, I am not modifying any of the header
information in the PRC (such as the name) and the ExgDBRead function calls
the DeleteProc function to try and delete the original PRC in ROM since I'm
trying to write the same named file out to RAM.
What I need in the end is a file with the same name in RAM as in ROM. When
the user runs the program it will automatically get the one from RAM.
I'm not sure how to proceed with getting the stream back out to RAM with
ExgDBRead. Should I modify the header information to change the name before
calling ExgDBRead which will cause a new PRC in RAM to be created with a
different name? Then can I call DmSetDatabaseInfo to change the name back
to the same as what's in ROM?
I'm not sure how to proceed but will try a couple different approaches. Any
tips you can give me would be appreciated. Thanks.
