Updating picture links in a PowerPoint document using JSL and VBA

johnmoore — Fri, 09 Jun 2023 23:35:58 GMT

I am working on an add-in to automate some reporting.

There is a report template PowerPoint file that includes links to image files of various charts and tables. (see attched)
When the user clicks the "add to active report" button, the appropriate image file will be overwritten so that the new chart or table will show up in the report.

The problem I am having is that I need to update the links in the PowerPoint document. I would like to be able to say "create new report", copy the template and default images into a new folder, and update the links in the the new PowerPoint file so that the point to the image files in the new folder instead of the image files in the template folder. Any ideas how I might do this?

Many thanks,

John

Hi @johnmoore, I faced something similar, I know the difficulty to keep updating packages using corporate templates in power point and need to update about 300 images from Anova, variability charts, Cpk reports, etc created in JMP where every power point package contains "basically the same charts", always in the same place, the only difference is the raw data needed for the specific report.

I am not really expert in VBA, but when you need something, you keep searching every where and do trial and error until you can make/find a solution.

This is the approach I follow, maybe you have something similar so far:

In JMP send through JSL your analysis (images) to a folder in your PC and assign a specific name to each image (never name them same because then only will overwrite). Once you customize in power point the location of each specific image and make the link for each of them.save it as a macro file (this will be your template).
Open your template and Run the macro any time you need a new report.
Finally save the file as no macro and with a different name to keep the template with images ready for next time.

Hope this can help you, I strongly recommend you to put password to the macro to avoid changes in the script.

Regards.
