In one of the dialogs in my Basic MSI project I have a checkbox that runs a CA when it is clicked. That CA sets 2 properties. I want to display the values of those properties immediately when the checkbox is checked. Currently I have to leave the dialog and come back to see the refreshed values. The following post makes it sound like this is possible, but I can't get it to work.
Can anyone post an example or provide some clarification. The article uses the term "Control" when there are 2 controls (1 for the checkbox and another for the field to be updated). It is not clear which one is which when the article uses the term "Control' for both.
I gave the steps in the documentation that you linked to a quick try, but I didn't see a way to specify SetProperty, even by typing it out, for a Subscription for the Text Area control that I specified to display TESTPROPERTY1.
This is a known limitation of Windows Installer (MSI). To the best of my knowledge, the only way to get an MSI dialog refresh behavior is to clone the affected dialog and use a twin-dialog method, where clicking on a button of one dialog displays the twin dialog. Please give this a try. Does it work for you?
Please let us know if you have any questions or concerns. Thanks!
Thanks for your reply Ian. I considered doing that... but wanted to avoid potential trouble if someone else modifies this in the future. I found a simple solution.
Recall that in one of the dialogs in my Basic MSI project I have a checkbox that runs a CA when it is clicked. That CA sets 2 properties. I want to display the values of those properties immediately when the checkbox is checked. Currently I have to leave the dialog and come back to see the refreshed values. All I had to do to make this work is this:
- The fields I want to refresh are Edit Fields for MyProperty1 and MyProperty2.
- In my Checkbox control I execute the CA
- Set Property MyProperty1 = [MyProperty1]
- Set Property MyProperty2 = [MyProperty2]
The fields get updated without leaving the dialog 🙂
