This was an interesting question that forced me to re-examine a number of things I thought I knew inside out. There can only be one listener socket for a given address/port combination. There can be concurrent connections to a service endpoint, because a connection is identified by both its local and remote endpoints, allowing traffic to be routed to a specific service instance. If you have other questions, please let us know.A TCP socket is an endpoint instance defined by an IP address and a port in the context of either a particular TCP connection or the listening state.Ī port is a virtualisation identifier defining a service endpoint (as distinct from a service instance endpoint aka session identifier).Ī TCP socket is not a connection, it is the endpoint of a specific connection. You can use the Make sure an edit box is not empty article as a starting point for this. If the entered data by the user is correct, then you can proceed further with the installation, otherwise you can use a spawn dialog and the user will have to enter again the related information. Please take a look on the Execute custom action on button push article which may be useful to you. You will further add this custom action as a Published Events on the Next > button in the same dialog where the user needs to enter the related information ( during the client installation). Also, the source file will be embedded in the MSI file but will not be deployed at install time with the other application files. This type of custom action can execute an application (EXE or DLL) or run a script (VBScript or Java script). Then you can go in the “Custom Actions” page and add a predefined Launch attached file custom action without sequence. For example, you can create your custom action as a custom action written in C# or a custom action written in C++. In order to achieve that you can implement your own custom action which verify if on the related address is the one where the server is hosted.
