multiple-instances

问题 Currently I am reading in host names from a file using a foreach command and using this hostname to connect to the device. All this is done within my TCL script. Is there a way I can run multiple instances of the script so that each device is queried separately? Something like a bash script similar to: for hostname in file; do log.tcl $hostname & done I believe this is similar to multi threading. Another question I have is that, when running multiple instances of a script, and each script

问题 I'm using a Swing Timer to execute animations in my program. In many instances, there are several different calls made to the animate() method at once, with a separate Timer created for each. I know that, because of the way Swing timers are designed, these all get executed together - all my animations occur at the same time. However, there are some instances where I need to wait for one animation to complete to execute another. Is there a way to make Swing timers execute sequentially - one

问题 I am trying to use four canvases stacked upon eachother but the contents of them won't display besides the contents of the one on the top. I put z-index values to them in order in which I'd like them to display but only the top one is displaying the contents. Their position is absolute and their z indexes are 1, 2, 3 and 4. Is there anything more to it that makes them not display? Or, how many canvases could I stack together in order for all of their contents to display? I have this: <div><

问题 I work in an engineering lab, not a computer science lab. As such, our in-house software is not the deliverable product. Instead, the in-house software is used to analyze engineering problems, and we deliver the results. This makes version control a living hell. Or perhaps I should just say that the standard "trunk and branch" version control tree structure doesn't seem to apply. I'm hoping someone can suggest a better way of doing things. For example, each engineering project requires adding

问题 I would like to know your opinion on the ideal approach of developing an multiple web app instance for SaaS. Just to give out a rough idea on what i am trying to do is: Suppose there is a web app, let say HR application (i.e. OrangeHRM). Where i as the service provider would have more than one clients. In my application, it could have multiple users with different roles and so on, so forth. What would be the ideal way to implement this in terms: modularity (adding new modules in the future)

问题 I have created a custom class in xcode: PaperPack and defined 2 instant variables: title and author - Then I alloc 2 instances of the class as below: PaperPack *pack1 = [[PaperPack alloc] init]; pack1.title = @"Title 1"; pack1.author = @"Author"; PaperPack *pack2 = [[PaperPack alloc] init]; pack1.title = @"Title 2"; pack1.author = @"Author"; Then how do I count and return number of instances I have created with that class? 回答1: No you can not get directly. Whenever you create in instance add

问题 Thanks for taking a look. I'm trying to used the jQ UI addClass / remove Class methods to expand an hr element upon clicking preceding sibling divs. jQ UI effects core enables smooth animated transition between two classes: http://jqueryui.com/demos/removeClass/. Additionally, hr must be added dynamically with $ to achieve the broader site design. Here are the pieces of the puzzle: My code renders rows of four 100x100px sibling divs. These divs don't have classes, but FEEL FREE TO ADD THEM IF

问题 I'm working on VB6 application, which is connected to MS Access database, so I don't want to allow user to open multiple instances of my application as this will create conflicts & alter connected database. Also, if user tries to open another instance, the currently running instance must be focused. How can I attain this? Thanks in advance.......... :-) 回答1: Use App.PrevInstance : 'this code would be in a bas module for start up.' Private Sub main() 'Check for previous instance and exit if

问题 I was wondering is it possible to create multiple instances of a single Activity in Android? I currently start my own inCall screen for a Voip Test by using the following code: public void initInCallScreen(String pName, String phoneNumber, int contactID, boolean callDirection, int lineID){ //starts in callScreen dialog final Intent myIntent = new Intent(context, CallDialogActivity.class); myIntent.putExtra("NAME", pName); myIntent.putExtra("NUMBER", phoneNumber); myIntent.putExtra("ID",
