SUMMARY
When you print a custom form created using version 1.0 of Microsoft Electronic Forms Designer, information in subforms may not print as expected. When E-Form Caching is turned on, information from a previous instance of the subform may print instead of the current data.



CAUSE
The instructions listed in the "Adding Modal and Modeless Subforms" section (pages 98-102) of the Microsoft Electronic Forms Designer "Developer's Guide" will place code in correct locations for reading subforms. However, it does not provide instructions for properly handling printing of subforms when caching is turned on.

The method outlined in the "Developer's Guide" is for the ReadTaggedControls function to be called in the Load event of a subform. When a subform is opened, ReadTaggedControls reads the subform's data from the MEF package. If a custom message is read and the Print command is issued before the subform is opened, the Load event for the subform does not take place. Consequentially, the ReadTaggedControls function is not called to retrieve the subform's data from the package. When caching is turned on, the cached data for the subform is used and will print.



WORKAROUND
To work around this problem, you must read the subform data from the package when the e-form loads, rather then waiting to read the data when the subform is opened. To do so, perform the following steps to add code to the ReadMessage function defined in the EFORM.BAS file: <ol> Open the E-Form project in Microsoft Visual Basic.</li> Open the EFORM.BAS file.</li> In the Proc: list box, select ReadMessage.</li>  Add the ReadTaggedControls function for each subform below the comment "Add code here to unpackage your data."

For example, if there is a subform named frmHardware, add the following line of code: ReadTaggedControls frmHardware, gPackage </li> Remove the ReadTaggedControls function from the Load event for the subform. From the Project window, select the subform and choose the View Code button.</li> From the Object: list box, select Form.</li> From the Proc: list box, select Load.</li>  Delete the following line of code: ReadTaggedControls Me, gPackage </li></ol>

The subform's data will now be read from the package when the form is opened and will be available to the print procedure regardless of when the subform is read.
