What does Application.DoE vents() do?

[NagarajanS]

Application.DoE vents() is the method wich is used to do any user interaction in the parent form.for example
while(true)
{
//some code
}
if you do any updation inside this while loop then the application will hanges.so if we want to elimate that condition just put "Application.Do Events()" inside the loop.

Why don't you post the Java code that you have and explain the problem you are getting in the code.

NagarajanS should have also mentioned that DoEvents is a VB function.

DoEvents function returns control to the operating system while a loop is still executing.

NagarajanS wants to know similar functions in Java.

I'd still like to see the Java code he has for this and where it's giving problems. In Java the thread responsible for painting is different from the thread running the whole application so I (for one) am not yet fully visualizing his problem in the Java context. Thanks for the explanation of what DoEvents does.

here is the code,
[CODE=java] private void PlayLinkActionP erformed(java.a wt.event.Action Event evt) {
// TODO add your handling code here:
LicenseFrame license=License Frame.getobject ();
if(license.Chec kLicenseKey())
{

/*
*The following methods are used to redate the values for the next play action
*/
_usersign.Repai ntjTable();
currentlog.Clea rCurrentLog();
comresult.Repai ntjTable();
logupdate.Clear TextArea();
trace.AppendLog (GetLogTime.Get Time()+": TibMainPage"+"S tarted");
CreateLogDir creatdir=new CreateLogDir();
//This initialisation is for reassign the static value
TibSignOnPage.e nablestoplink=1 ;
threadlist=new ArrayList();

// int sessionnumber= TreeViewDesign. Session_no;
// System.out.prin tln("sessionnum ber:"+sessionnu mber);

Runnable runnable = new Runnable() {
public void run() {
InvokeLaterMeth od();
}
};

SwingUtilities. invokeLater(run nable);
for(int usercount=1;use rcount<TreeView Design.Totaluse r+1;usercount++ ) {
for(int sessionid=0;ses sionid<sessionn umber;sessionid ++) {
String filename="";

filename=Double .toString((( TreeViewDesign. Totaluser-(TreeViewDesign .Totaluser%(jav a.lang.Math.pow (10,(Integer.to String(TreeView Design.Totaluse r).length()-1)))))*10)+user count);
filename=filena me.substring(0, filename.length ()-2);
filename=filena me.substring(1, filename.length ());
// System.out.prin tln("filepath:" +TreeViewDesign .directorypath+ "/"+TreeViewDesig n.prefix+"_"+fi lename+".xml");
TibSignOnPage signon=new TibSignOnPage(T reeViewDesign.d irectorypath+"/"+TreeViewDesig n.prefix+"_"+fi lename+".xml",S top,PlayLink,Pa useLink);
signon.setName( TreeViewDesign. prefix+"_"+file name);
signon.start();
threadlist.add( signon);



// _usersign.Updat eTable(TreeView Design.prefix+" _"+filename,"Co nnected",sessio nnumber);
trace.AppendLog (GetLogTime.Get Time()+": TibMainPage"+Tr eeViewDesign.pr efix+"_"+filena me+"Started");
try
{
Thread.sleep(Tr eeViewDesign.Th readtime);
}
catch(Exception ex)
{
ex.printStackTr ace();
}
}
}

PlayLink.setEna bled(false);
Resume.setEnabl ed(false);
PauseLink.setEn abled(true);
Stop.setEnabled (true);
}
else
{
System.out.prin tln("license expired");
}
}

i think the code is hard to understand,ok let me explain some think here where i get struck,
inside the for loop i am starting the thread class like this
for()
{
//thread start method
here i am updating the jtable for each increment!!!!
}[/CODE]
what will happen here is,until the for loop exits the updation will not happen.is it correct? i am want to update the table inside the for loop inself.how to do that?
Can you understand the problem?

[r035198x]

Are you sure it's not updating after adding the data?
If you're sure then you can call the resizeAndRepain t method of the JTable.

[NagarajanS]

i tried that but no use.Any other option?
ok let me know how will you update any of the control which is inside the while loop?
