  • Pop-up window in Java Swing

    - by Gabriel Parenza
    Hey, Can someone suggest me how to implement a pop-up window in Java Swing. I want the pop-up window to be a modal window (user cannot return to the main window when the pop-up is open). I tried doing it using JDialog but it allows only one widget for user input to be in it whereas I need multiple widgets. I may be wrong here but this is what I was able to do. Appreciate your help.

  • How do I specify a keys password with MSBuild for the purpose of using Hudson?

    - by Brett Ryan
    We have just setup our hudson server to build .NET projects which seems to be working fine, however for projects that require a password when signing the assemblies I can not figure out how to tell hudson what the password is? For us the password is asked the first time a developer checks out the source code and they open with visual studio, how is this stored? Can we just place a secret file somewhere on the server?

  • Can regular expressions be used to match nested patterns?

    - by Richard Dorman
    Is it possible to write a regular expression that matches a nested pattern that occurs an unknown number of times. For example, can a regular expression match an opening and closing brace when there are an unknown number of open closing braces nested within the outer braces. For example: public MyMethod() { if (test) { // More { } } // More { } } // End Should match: { if (test) { // More { } } // More { } }

  • MainMenu with Images (WinForms, C#)

    - by j-t-s
    Hi All I have a MainMenu in my app and I would like to have little icons relevant to the Item in each menu. But the MainMenu control does not support this. I would use the MenuStrip control, though that is a pretty ugly option in my opinion. Does anybody have any suggestions? Are there any free/open source alt's out there, or would it be easy/possible to implement that feature into the existing MainMenu control? Thanks

  • Mysql: Perform of NOT EXISTS. Is it possible to improve permofance?

    - by petRUShka
    I have two tables posts and comments. Table comments have post_id attribute. I need to get all posts with type "open", for which there are no comments with type "good" and created date MAY 1. Is it optimal to use such SQL-query: SELECT posts.* FROM posts WHERE NOT EXISTS ( SELECT comments.id FROM comments WHERE comments.post_id = posts.id AND comments.comment_type = 'good' AND comments.created_at BETWEEN '2010-05-01 00:00:00' AND '2010-05-01 23:59:59') I'm not sure that NOT EXISTS is perfect construction in this situation.

  • How do I access Glassfish V3 Administration Console Website from a remote host

    - by Tom
    I have installed Glassfish v3 on a standalone server running ubuntu-server 9.10. I can open the Admin website if I use a browser running on the server by browsing to: http:// localhost:4848/ I would like to access it from a remote machine by browsing to something like http:// mydomain.com:4848/ The firewall is definitely allowing traffic through on that port (4848) and I can access the application server by browsing to: http:// mydomain.com:8080/ How can I allow remote access to the administration website?

  • How can I programmatically tell if a caught IOException is because the file is being used by another

    - by Paul K
    When I open a file, I want to know if it is being used by another process so I can perform special handling; any other IOException I will bubble up. An IOException's Message property contains "The process cannot access the file 'foo' because it is being used by another process.", but this is unsuitable for programmatic detection. What is the safest, most robust way to detect a file being used by another process?
