Error after printing

I am receiving a fatal program error after I print to a network printer from my netbook.  I am using ddoc32.dll and I have followed sapero's asm add-in's needed for that dll.  The information I want to print does print and then I receive the error.  I put a messagebox after the place where I call the code to print and it makes it to there OK.  It looks like the error occurs after it leaves the windows message subroutine.  The thing that is annoying is that it runs on my desktop just fine.  Anyone have any ideas what to try?

Thanks,
Clint

What add-ins are needed?  I've used ddoc for years with no problems.

mrainey,

It has to do with dpTextWidth function.  Any dp.. function that returns a single or double precision value doesn't clear the stack properly.  Follow the thread below.

I am beginning to not think it is EBASIC or ddoc, but I don't know for sure.  It could just be my netbook although I have never had that error on there with any other program.

Update.  I was using PRTDIALOG to select a printer and passing that printer to ddoc using dpSpecifyPrinter.  I like PRTDIALOG better, but something caused an Access Violation again. Probably sending it to dpSpecifyPrinter would be my guess, but that returns a long value, not a float or double. The code below shows the changes I had to make.  I don't know why it didn't work and that bugs me.

The one thing I learned is to make sure all supporting files are installed and registered on the computer that will be running ddoc.  DDOC.EXE, DDOC16.DLL, DDOC32.DLL, and DDOC_JPG.DLL.  I think that that was what was causing all of my problems.  I will probably in the near future paste the original code back in and see if I am right.

Later,
