| | By assigning the date object to a session variable at login, then simply displaying that date at every other page load rather than creating a new date (as you are doing now). A new date object will always hold the current time at the time of construction (at least when … |
| | Re: Java Project Oh, this is classic, posting a question onto a thread about projects in Java (in the Java Forum of course) that is two years dead, and asking for a project in VB. This question is just guaranteed to get a lot of responses, just none that the poster will want …  |
| | Please don't cross post, it is considered rude. Please continue with the original thread: [url]http://www.daniweb.com/techtalkforums/thread77555.html[/url] And do what was asked of you there (namely repost your code using code tags, in that thread). |
| | Try using POI (it is an apache project) or JExcel. You won't be able to do it with the Jet engine AFAIK. You could always break up the spreadsheet (I know, this is not an option). |

| | No, because in BlackJack (21) 10 - King are all 10 and an Ace is either 1 or 11. I would say, when an Ace shows up, total the rest of the cards, then decide how much to assign to the Ace depending on the difference between the current total … |

| | If you are writing to the logfile in the following manner [inlinecode]scriptname >> logfilename[/inlinecode] Then change it as follows (for a really quick fix): [inlinecode]scriptname | tee -a logfilename | mailx -s "scriptname" email@address[/inlinecode] |

| | "Linking" 2 or more JSPs is not the problem. Most projects contain many JSPs, Servlets, Beans, Tags, Listeners, and other components. The problem is attempting to use them from two different machines. They need to be part of the same application. Eidt: But, as mentioned above, you can, using HttpUrlConnection … |
| | I'm sorry, but this ia a Java forum. JavaScript != Java. Please get this moved to a JavaScript forum.  |
| | Well, start coding. If you have a problem post again, with your code and a description of your problem, along with any error messages (complete) and we will help, but we are not going to write it for you. |
| | As in? What is your problem? What are you attempting to do, and what is actually happening? Are you getting errors? Have you, as yet attempted to code anything? If you have any code, post it, and answer the questions above, then we can help you a bit more. If … |
| | What do you mena, to no avail? It definately should work. Vectors may not be the best choice (at least from an efficiency standpoint), but it should work. It would probably be helpful to show the code and provide the complete detils to any error you may ahve gotten. |
| | No, it will compile just fine without it. main, as far as the compiler is concerned, is a method just like any other, but when you try to execute a class and the method definition [inlinecode]public static void main(String[] args)[/inlinecode] does not exist, you will get the exact error message … |

 | Re: Runtime class A note on the file separator, the command line intrepreter is the complete reason why "\" is always used on Windows. Almost, if not, all programming languages can use "/" for paths in Windows, but the command line interpretor interprets "/" as the option argument indicator, so it needs something … |

| | What it looks like is, either the user "postgres" doesn't exist in the DB, or the provided password is wrong. Edit: Or the provided user does not have permission to access the Tablespace/SID/whatever_it_is_called_in_PostGreSQL requested in the URL (the part after localhost). |
| | Re: need help I haven't even looked at that code, because you haven't really asked a question. What part of this are you having problems with? Are you getting errors while compiling? If so, post them. Are you getting errors while running? If so post them. Are you seeing results other than what … |
 | Re: need help What is "the necessary result"? Are you getting compile errors? If so post them. Are you getting runtime errors? If so, post them. Are the results you are getting something different from what you expect? If so, post exactly what it is expect, and, exactly what it is you are … |
| | I assume the error says that it does not implement some method or something to that effect, right? It would have really helped to know what the error was, but I believe I have found it anyway. This line [code] public void actionperformed(ActionEvent event) [/code] should be [code] public void … |
| | Or the "equals" method of String, in this case. |
| | At the moment, if you are just learning, neither. Learn how to write programs using a simple tet editor (with syntax highlighting, maybe), while compiling, executing, and packaging from the command line. Once you have a good grip on all of that, then it would be a good idea to … |

 | First of all, never place anyting into the "bin" directory of jdk (or really in any directory of the jdk/jre). Second of all, does your class contain the following method defintion: [code] public static void main(String[] args) { // your code here } [/code] and I mean that exact method …  |
| | Well, I see no [inlinecode]<HTML> </HTML>[/inlinecode] or [inlinecode]<BODY> </BODY>[/inlinecode] tags, so, if that is suppossed to be a complete HTML document, it is not. I, myself, don't know how those OLE packages are suppossed to work, so I can't even begin to say whether this tip is correct or not. … |
| | In mysql you not only have to create a user and set a password, you also have to designate from where (and how) that user is allowed to connect the DB. Per default, root can only connect from localhost using the sock file, but, in Java, you will be attempting … |

| | Re: Creating Login [QUOTE=thekashyap;334507]Storage of the list of Username vs ID most probably has to be done persistantly.
