Hi

I have a TextBoxes Dialog where the user insert the product key during installation.
Once the user click Next, an immediate CA is called to validate the key. I want the CA to return a value so that in case the key is not valid, the user will not be able to continue to the next UI Dialog. (When I have this property returned from the CA, I can add it to the condition of the Next button on the ControlEvent table.)

Note: I don't want the installation to terminate if the key is not valid. Only to halt the UI dialogs.


So, just to make it more clear -
The only question here is how to return a value (or pre-configured property) from immedate CA to the msi tables ?

Thanks for any assistance.

MsiSetProperty()

Sorry, but I couldn't find any examples of how to use the MsiSetProperty() function with VB.NET.

You can't. VB doesn't create "real" DLLs but ActiveX. You should use C to build the DLL, or use VBScript.

Oooops.

Thanks Stefan.

In that case I'll leave this issue for the future when I have more time...

The validate key deferred CA runs now during the Install phase. It's probably better to validate after the key is entered, so that the installation doesn't even start in case the key is not valid.
