Issue: Unhandled Exception when Opening a Custom Report
If you have been working on a custom report and
after saving it you get an unhandled exception error when you try to reopen it,
you probably want to know if there is a way to fix that error.
The answer to that
question depends on whether you know the last few operations before saving the
report. In other words, do you have a good idea of what broke the report? If
you know the cause of the error, you can fix it. Otherwise, the report may be
corrupted and unrecoverable.
If you know what
operation broke the report, here is the procedure to get access to the report
in the Report Designer.
Open the factory
database using the Microvellum SQL CE Viewer. Double click on the
ReportTemplates table to open it. In the Name field, find the report that
throws the exception. In the field named ReportFile for that row, right-click
on the cell containing the "ByteArray" data and click "Save File
to Disk." In the Save As dialog box, navigate to where you want to save it,
give it a name, and an .MRT file extension and click Save.
Open a known good
report in the Report Designer (Toolbox or Production). Click the Open button,
as shown in the attached screenshot. Navigate to the location you saved the MRT
file, select it, and click Open.
This will open the
report in the Designer without any dataset connection. What that means on a
practical level is that you won't be able to Preview the results of your work
after revising the report. You will need to know what action broke the report,
undo that action by setting it back to what it was before, or fix it. Then save
the report and continue with the procedure below.
Once the MRT file
has been repaired, the next step is to import that file back into the factory
database. If the Microvellum SQL CE Viewer is not already open, open it, and
double click on the table ReportTemplates to open it. In the Name field, again,
find the report that throws the exception. In the field named ReportFile for
that report, right-click on the cell containing the "ByteArray" data
and click "Import File from Disk." Navigate to the location of the
MRT you exported above, select it, and click Open.
If the repair was
successful, you will now be able to reopen Toolbox or Production and work with
the report.
