Programming for Priority Web
Advanced programming for the Priorityweb interface is basically the same as programming for the Windows interface. However, when working with the web interface you must keep in mind the different method used to access thePriority server. As a result, the following exceptions apply:
- When working with attachments, only files located in the system/mail folder can be interacted with by the user. Any attachments uploaded by code should be stored in this folder if users need to interact with the attachment.
You cannot use the EXECUTE command to run entities that require input from the user or that display output. This is because the entity is executed on the server and any interface opened will be displayed on the server rather than on the local computer.
Note: This also extends to ACTIVAT and ACTIVATF if they run an entity that requires input, such as the SHVA program.
- You cannot add the following syntax to a procedure
step in order to open a form when
running a procedure:
EXECUTE WINFORM 'ORDERS';
Instead, add a new procedure step with the desired Entity Name and the Type F.
- You cannot use the following syntax to a procedure step in order to
execute a document when running a procedure:
EXECUTE WINACTIV '-P', 'WWWSHOWORDER', 'ORDERS', :TMPORDERS;
Use WINHTML instead.
- If the value in the Application column is 4 characters long and ends in 0 (zero), the entity in question will not be displayed when working with the web interface.
In procedures that load or export data, add the UPLOAD or DOWNLOAD step to upload/download the file in question from the local computer to the server (or vice versa). Specify the file name in the UPLOAD/DOWNLOAD procedure step.
Example: See the UPLOAD procedure step in the LOADFNC1 procedure and the DOWNLOAD step in the ULOADFNC procedure.
Note: This step is not necessary when opening or saving a file using an INPUT parameter of type CHAR that is flagged to display a browse button (in the Procedure Parameter Extension sub-level form).
