SUMMARY

This article covers these three primary ways to create and then logon to a CDO (1.1, 1.2, 1.21) Session from Visual C++:

  • With prompt for Profile
  • Without prompt for Profile
  • Creating a dynamic Profile programmatically

With Prompt for Profile

Creating a Dynamic Profile Programmatically

    /**********************************************************/ 
    // DYN_PROF.CPP
    // ------------
    // This program demonstrates how to use the Session->Logon
    // of the CDO (1.1, 1.2, 1.21) Library via VC++, to create
    // a dynamic Profile at Logon. This is the likely method to
    // use if the application will be run as a Windows NT Service.
    // 
    // The key point of this sample is the final parameter to the
    // logon, which allows for creation of a temporary profile
    // for the session. The CDO (1.1, 1.2, 1.21) Library will
    // generate a random name for the profile.
    // 
    // For an authenticated profile, the format of the string is:
    // 
    //   <server name> + \n + <mailbox name>
    // 
    // where the server and mailbox names can be unresolved. Note
    // that the mailbox name is not the messaging user's display
    // name, but rather the alias or account name used internally
    // by the user's organization. For example, "johnd" should be
    // used instead of "John Doe".
    // 
    // For an anonymous profile, the format is:
    // 
    //   <server distinguished name> + \n\n + "anon"
    // 
    // where the distinguished name of the server takes the form:
    // 
    //   /o=<enterprise>/ou=<site>/cn=Configuration/cn=Servers/cn=<server>
    // 
    // 
    // This sample demonstrates an authenticated logon, and
    // requires Visual C++ version 5.0 or higher.
