问题 I had created a COM+ domain partition then mapped it to a Windows 2008 server machine and imported a COM+ application into it. I tried using the following C# code to activate an object from that specific partition on the server remotely: //partition guid Guid guidMyPartition = new Guid("41E90F3E-56C1-4633-81C3-6E8BAC8BDD70"); //parition moniker string uri= "partition:{" + guidMyPartition + "}/new:MyObject"; Type t = Type.GetTypeFromProgID("MyObject", "MyServer"); MyObject obj = (MyObject

Node+Passport.js + Sessions + multiple servers

阅读更多关于 Node+Passport.js + Sessions + multiple servers

问题 Passport is great. I now discovered that I have some problem with how it handles sessions. I must be using it wrong. All works well for me with login + sessions + user data I store in my database. However I find that when I move to production environment (cloud on EC2 with multiple servers), I lose the login session each time. This is now clear to me - probably happens since the session is unique to each server. So my question is - how do I get around this.. I guess I will need to store my

I've seen that this is possible with the universal apps as there are some apps that can already do this (e.g. Calculator, Edge). I have already tried searching on Google, on Microsoft's API reference, and here to no avail. I'd really appreciate your help. 回答1: UWP/store apps use no multiinstance, but use multi-view style.

Checking for successful uninstall

阅读更多关于 Checking for successful uninstall

问题 I'm trying to automate an install process in which I uninstall a previous version and install a newer version over the top. How should I test (in my bootstrapper, coded in C#) if the uninstall was a success? This is currently how I'm launching the uninstall. Process p = Process.Start("msiexec", /*various switches*/); p.WaitForExit(); I'm also currently tangling with dynamic multiple instances, which really bend my mind, so handling this problem within WiX itself is difficult if not impossible
