| Product: | VB Guide 2.x (all versions up to and including 2.2.3) |
| Problem: | VGet returns not found when SPELVideo scale is not full |
Symptoms
After executing VRun, subsequent calls to VGet always
return not found.
Causes
If the VideoControl property is not set for the SPELCom control, and
the VideoScale property of the SPELVideo control is not Full, VRun does not
execute properly.
If the VideoControl property has been set, then the correct error occurs when VRun is executed with VideoScale set to anything other than Full.
In the versions of VB Guide 2.0 and Vision Guide 2.0 prior to 2.3.0, the same buffer is used for vision search and live video display. If the display is being scaled down from full size, the search is not allowed.
Remedies
In all versions of VB Guide 2.0 prior to 2.3.0, you must
use full scale video when using a SPELVideo control. It is also
recommended that you always set the VideoControl property when using a
SPELVideo control.
Status
Fixed in VB Guide 2.3.0.
