如何获取由 c++ dll SetMsiProperty api 设置的 installshield 2019 中的属性值？

Question

I am using installshield 2019 professional. I want to validate username/password provided by user. I have written a custom action in c++ dll and from that setting a property using SetMsiProperty method. Now, I am trying to use that property value in the condition to spawn dialogue. But in the installer I could not able to get the property. Is that the same way to do that? Please help.

Thanks in advance.

Generally it is bad form to take a password and store it in a property at runtime. If you log your install and then search for that property, or password value, you see it right there in the log plain as day. Bad security!

To actually answer your question is fairly easy especially if you have any experience with.Net. Since you're using SetMsiProperty can you guess the answer? Try looking for GetMsiProperty.

Sometimes MS changes it up to MsiGetProperty
