Custome dialog based on condition.

[Codename K]

Hello,

The installer I am creating needs to show a custom made message dialog based on condition. The installer will search for a registry entry (this part is OK) and the value being true the custom dialog have to be displayed. Otherwise not. How can I do that?

Hello,

In order to condition a dialog's appearance use the “Show only if...” tree context menu item. So, during installation, the dialog will be displayed only if the specified condition is met. You can also take a look on the Display a dialog based on a checkbox state tutorial which may help you.

Please let us know if that helped, otherwise give us more details.

Best regards,
Dan

Hello,

Thanks for your support. What if the custom dialog can only go to the Next dialog if the registry value is true? I mean a "Try Again" button. Only the dialog can go to the next dialog is when the registry value is true.

Hi,

In order to achieve that you can go in the "Dialogs" page and select the [Next] button on the previous dialog from the "Install Sequence" where your custom dialog is added.
In the Published Events of the [Next > ] button select the Display a specific dialog published event and add in the "Condition:" field the public property of that is associated with your search(e.g. REGISTRY_KEY_EXISTS). So, the next dialog will be only displayed if the value of the search is true.

You can also add a predefined Display message box custom action without sequence and on the same [Next > ] button add a new Published Events.
From the new control event window you can select Execute custom action. Edit the events options like:
Argument: MessageBox
Condition: field: NOT REGISTRY_KEY_EXISTS
So, the message box will appear only if the search is not true.

If you have other questions, please let us know.
