<div>
where have you put that code?<br />
have you checked it is getting executed?<br />
<br />

</div>


<div>
i put it in main(). I also use <br />
if( instance.jButton1 != null)<br />
{<br />
&nbsp; &nbsp; &nbsp; instance.jButton1.doClick(<wbr />);<br />
&nbsp; &nbsp; &nbsp; System.out.println(&quot;after doClick()&quot;);<br />
}<br />
<br />
it can display &quot;&nbsp;after doCLick() on console.
</div>

}<br />
<br />
it can display &quot;&nbsp;after doCLick() on console and still wait for my click before it can run!!!!!!!!!!!!!!!!!!!!!<br />

</div>


<div>
you exit the application straight after you call it<br />
when did you want it executed?<br />
<br />
<br />

</div>


<div>
i comment the exit() but it doesn't work. It' is very weird
</div>


<div>
 &nbsp;You shouldn't be calling doClick() from main()<br />
&nbsp;<br />
what is it you are trying to do?<br />
<br />

</div>


<div>
Try the following:<br />

<pre><code class="code-1 nolinks" id="code-265426"><span>if( instance.jButton1 != null)</span>
<span>{</span>
<span>	EventQueue.invokeLater(new Runnable() {</span>
<span>		public void run() {</span>
<span>			instance.jButton1.doClick();</span>
<span>			System.out.println(&quot;after doClick()&quot;);</span>
<span>		}</span>
<span>	});</span>
<span>}</span>
</code></pre>
</div>


<div>
well, instead of click a button to execute my program, i want it run automatically. It used to work.<br />
&nbsp;More precise to say, i leave it inpublic void run(). <br />
PS: using netbeans now.
</div>


<div>
just call whatever that button does directly. Theres no reason to use doClick()<br />
<br />

</div>


<div>
but i have built that project with a click to run. just want to modify it to run automatically.
</div>


<div>
what does your actionPerfomed() method do?<br />
<br />

</div>


<div>
&gt;&gt;just want to modify it to run automatically.<br />
<br />
Did you run the code i posted?
</div>


<div>
here is my man<br />
<br />
public static void main(String args[]) {<br />
&nbsp; &nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; &nbsp; &nbsp; java.awt.EventQueue.invoke<wbr />Later(new Runnable() {<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void run() {<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Installer instance = new Installer(); <br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; instance.setVisible(true);<wbr /><br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(instance.jButton1 != null)<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; instance.jButton1.doClick(<wbr />);<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.println(&quot;after doClick() &quot;); <br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //System.exit(0);<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //new Installer().setVisible(tru<wbr />e); // only this line is generated by netbeans<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br />
&nbsp; &nbsp; &nbsp; &nbsp; });<br />
&nbsp; &nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; }<br />
<br />
<br />
i don't see the different between mine and yours CEHJ :)
</div>


<div>
No that's alright - didn't know you were starting the gui like that. What's happening then? If it's not working, can you put an else in there too to debug?
</div>


<div>
&quot;It doens't work&quot; means it still wait for me to click before it can run. <br />
&nbsp; let me try else to debug.
</div>


<div>
if(instance.jButton1 != null)<br />
{<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; instance.jButton1.doClick(<wbr />);<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.println(&quot;after doClick()&quot;);<br />
}<br />
else<br />
{<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;System.out.println(&quot;in else&quot;);<br />
} &nbsp; <br />
<br />
---&gt; it still prints &quot;&nbsp;after doClick()&quot; and just waiting for a click<br />
<br />
<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
</div>


<div>
actionPerform() does many tasks. ALl tasks are executed properly. Only doClick() still doens't work. 
</div>


<div>
check your calling doClick on the right button and that you have added the action listener to the button<br />

</div>


<div>
i did . there is only 1 button on my application :)
</div>


<div>
did you check that variable references the same button that you added toy uor gui<br />
<br />
try this:<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; instance.jButton1.setText(<wbr />&quot;XXX&quot;);<br />
<br />

</div>


<div>
somehow it works when i use netbean 5.5 first. Then i use netbean 5.0 it works now. no idea. <br />
&nbsp;Just wonder how to force a button to load a picture when a program launch. THanks
</div>

<br />
Sounds like something wasn't compiled so you were accessing old classes<br />
<br />
&gt;&nbsp;Just wonder how to force a button to load a picture when a program launch. THanks<br />
<br />
Just create an ImageIcon when you launch<br />
<br />
<br />

</div>


<div>
or for a more involved example ssee here<br />
<br />
<a href="http://helpdesk.objects.com.au/java/how-can-i-create-splash-window-in-swing" rel="ugc">http://helpdesk.objects.com.au/java/how-can-i-create-splash-window-in-swing</a><br />

</div>


<div>
right now i create one more button. I go to property and select a icon to cover that button. However, when the program run, i can't display that icon on that button. So i think I must force it. I guess i use instance.button1.setIcon()<wbr />. But i dont know parameter.
</div>


<div>
setIcon(new ImageIcon(image));<br />
<br />

</div>


<div>
I also include my image in Source Packages-&gt; resource-&gt;pix.jpg. how do i point to pix.jpg? THanks
</div>


<div>
i follow your guide. It works perfectly only if i let user click on button to run program. However, it didn't load if i use doCLick().<br />
PS: now there are 2 two on my program. one &nbsp;has icon on it, and one just do click to execute program.
</div>


<div>
make sure the resources are added to the classpath of both apps<br />
<br />

</div>


<div>
oh I just either comment or uncomment doClick() . Everything else is the same.
</div>


<div>
make sure you put the loading of the image in a place that gets run by both apps.<br />
<br />

</div>


<div>
i move those load icon code to constructor. it doesn't load. maybe thread problem???
</div>


<div>
to which constructor?<br />
<br />

</div>


<div>
to the constructor of public installer() 
</div>


<div>
post the constructor code and I'll have a look at it<br />
<br />

</div>


<div>
 &nbsp; &nbsp;public Installer() {<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; initComponents();<br />
&nbsp; &nbsp; &nbsp; &nbsp; this.getContentPane().setB<wbr />ackground(<wbr />new java.awt.Color(102, 0, 0));<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br />
&nbsp; &nbsp; &nbsp; &nbsp; URL image = getClass().getResource(&quot;/r<wbr />esource/ba<wbr />nner_SM.jp<wbr />g&quot;);<br />
&nbsp; &nbsp; &nbsp; &nbsp; jButton1.setIcon(new ImageIcon(image)); &nbsp; &nbsp; &nbsp;<br />
&nbsp; &nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; &nbsp; &nbsp; //frame.setLocation(x, y);<br />
&nbsp; &nbsp; &nbsp; &nbsp;// this.setLocation(450, 300); // x respect top left; y respect top <br />
&nbsp; &nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; &nbsp; &nbsp; this.setLocationRelativeTo<wbr />(null);<br />
&nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; &nbsp; &nbsp; <br />
&nbsp; &nbsp; }
</div>


<div>
you sure the classpath is correct.<br />
how do you run it?<br />
<br />

</div>


<div>
i am sure the path is correct. Now i comment doClick() &nbsp;and just run. I can see a red background color, but not the picture.
</div>


<div>
i guess the doClick() take away the process of loading icon in constructor. Could you please help to make a thread for doClick()? thanks
</div>


<div>
you don't need a new thread.<br />
can u post an example that shows the problem and I'll see if I can see the issue<br />
<br />

</div>


<div>
where is banner_SM.jpg, and what is the classpath you are running it with?<br />
<br />

</div>


<div>
this is a new problem so we should open a new question to work out whats wrong<br />
<br />

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
