问题 I'm using a windows 7 PC When I try to test an smtp connection through telnet giving the command: telnet smtp.gmail.com 25 It shows a message: could not establish connection to host, on port 25: connection failed" How do I get my PC to establish a connection with the smtp host on port 25?

If I used 5 threads, there would be 5 None returns before the list is being put out.

问题 I am trying to run a program, running on the hard drive, that uses Microsoft Jet OleDB to open and get info from an MS Access database.

问题 As the release date for the public beta of SharePoint 2010 is coming closer and closer, I'm wondering how to set up a developer machine for it. I've heard that for developing on SharePoint a 64 bit system is needed and that Microsoft advises to use Windows 7 64 bit and install SharePoint 2010 on it. I think that won't be an option for me as I only have one computer here at work and I don't like to install SharePoint on the same machine that I use for my normal office work (email stuff,

问题 Quickie question: I'm toying with some of the new taskbar APIs in Windows 7 and have gotten Recent Items on my Apps jumplist to show up, but I would like to display them under a different title than the filename (most files my app will be opening will have very similar names). I don't see any way to do that with the IShellItem interface, though. Would I have to use custom categories and IShellLinks to accomplish this? For reference, my current code looks like this: void AddRecentApp(const
