Here's our situation in a nutshell:
A old client called and wants to make revisions to a project we built
back in 2002. After loading the code in and massaging it to get it
compile in 2006r3, we've made our revisions. The problem we're
having now is that there are graphic (canvas.backdrop) changes and
canvas.visible=True/False states across the whole interface. When
it's compiled for Windows, we're running into the flickering/flashing
problems with the refreshes. I have tried various other options for
drawing the changes, double buffering the graphics,
erasebackround=false states and nothing is working. I have used the
new code in small, independent apps just to check that I had the
programming right for the refreshes and they worked 100%. But when I
move that code into the main app (4 years old), they still flash. I
have hit a dead end.
My boss has asked if anyone has any suggestions on consulting
services to go over the code to find anything. The fact that I can
build alternate "Proof of function" apps independently that are 100%,
and then do not work within the old app tells me that there's just
something with using the 4 year old code that the compiler doesn't
like. FYI, when "printed" out, the code runs for 147 pages, so it's
not a small program that we can just re-program from scratch and be
all set.
I've likewise re-loaded 4.5.1 to try to re-compile the code, and the
app that's created throws all kinds of exception errors.
Any insight would be great, thanks.
