The
EZTwain Pro 3 toolkit includes a file of PowerScript external
function declarations (eztwain.txt) translated automatically
from the eztwain.h C/C++ header file. Download
and install the developer kit if you have not already, and
look under \Program Files\EZTwain\PowerBuilder.
Note:
If you experience run-time errors when calling certain EZTwain
functions, check the declaration of the function. When we
first added support for PowerBuilder, functions with string
parameters or return values were incorrectly declared with
an 'ALIAS' clause - simply remove the ALIAS clause and the
function call should work.
EZTwain
Pro 3 installs all its DLLs into the Windows System folder,
which should be sufficient to make them automatically accessible
from your programs.

Software has written a nice article introducing TWAIN
and showing how to use our free 'Classic' EZTwain from PowerBuilder.
The article is in the archived Issue
7/1 of PowerTimes. Note - the sample
code with that article should work with EZTwain Pro simply
by changing the DLL name from eztw32.dll to Eztwain3.dll.
We
strongly recommend starting with a single basic call to EZTwain
(TWAIN_Testing123 or TWAIN_AcquireToFilename) - testing that,
and adding additional calls one-by-one as needed, to reach
the desired behavior. EZTwain is designed to be used in exactly
this way.
If
you wish to redistribute the EZTwain Pro DLLs with an application,
or within an organization, see the EZTwain
Pro Licensing Page.
Please
contact Dosadi technical support if you encounter any problems
using EZTwain Pro 3. We are committed to resolving such problems
promptly. |
