Hello,
i have upgrade from CVI 4 to CVI 5.0.1 and have several Problems to run my
old
programs written under CVI 4.0 with the Runtime Engine coming with CVI5.
My programs run much slower, then with CVI4.
I have compiled them under 5.0 but with no change.
I have find out that the problem occurs when i read something
from the comport (perhaps cause i use a while-loop).
For example:
In CVI4 the following code take about 3 second to complete, in CVI5 about 40
second.
while(!read_gps_wait_for( GPS_IDENT ) )
{
ProcessSystemEvents();
if (quit_program) return(0);
}
If i do not call ProcessSystemEvents() in the loop, the function need 3
second to complete,
but without ProcessSystemEvents() i can´t press a button to
cancel.
Which is the difference between ProcessSystemEvents in CVI4 and in CVI5?
what was modified?
If i reinstall the RuntimeEngine coming with CVI4, everthing run fine.
Any help or advice would be appreciated and apology for my bad english
Best regards
Gregoire Diehl
