Speed up application start by adding own application classes to classes.jsa

To speed up the startup time of the JVM, the Sun developers decided it is a good idea to precompile the standard runtime classes for a platform during installation of the JVM. These precompiled classes can be found e.g. at: $JAVA_HOME\jre\bin\client\classes.jsa My company currently develops a Java standalone application which brings its own JRE, so it would be a fantastic option to speed up our application start time by adding our own application classes to this jsa file, too. I don't believe the JSA file was created by magic, so: How is it created? And how can I trick the JVM into

Can I have an android activity run only on the first time an application is opened?

∥☆過路亽.° 提交于 2019-11-28 05:06:18
OK, so I'm playing around with an android app. The 90% use case is that users want to go straight to the primary list screen to find what they're looking for. That's what I want as my default screen. The first time a user loads the app however, some configuration is required before their list screen is of any value to them. So my question, is how I can go about displaying the configuration activity the first time the app is opened up, and then the list screen for future openings. I also want to put a demo button on the configuration screen, so I suppose more than just detecting that it's the

I have edited the .bashrc file to add this line: xterm "ls" But this does not work. Please suggest what should I do to acheive this.

I'd like to present modally, at first startup, a tutorial wizard to the user. Is there a way to present a modal UIViewController on application startup, without seeing, at least for a millisecond, the rootViewController behind it? Now I'm doing something like this (omitting first-launch checks for clarity): - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // ...

How to auto execute a macro when opening a Powerpoint presentation?

故事扮演 提交于 2019-11-28 02:01:36
I have a pretty basic question, but could not find the answer on internet. In Powerpoint 2010, I have a macro that I would like to be executed everytime the Powerpoint document is opened. How to achieve this ? Thanks ! Try to write this function. Sub Auto_Open() MsgBox("welcome") End Sub Replace the msgbox in your code. While Auto_Open doesn't run in a PowerPoint presentation, you can fake it. Add a CustomUI part to the presentation, then use the CustomUI OnLoad callback to run code when the presentation opens. The CustomUI part needs no more than just the CustomUI tags. Get the Custom UI
