By casting the return value to the correct type. If you're using .NET 2.0, you should use the specialised dictionary instead, which will return the right type to you.

My current project requires that I build a Java project along side some C# projects using Nant. Is this possible? I am completely new to Nant, but didn't see anything about javac in the task list available.
Any help would be appreciated, and an example would be great
Thanks much.

NAnt is a port of Ant, which runs on Java. I doubt they talk to each other, but perhaps you can use Ant for the Java portion ?

Thanks Christian,
Sadly, the build team here at work insists on only using NAnt, and the program had to be in Java because of a legacy issue... so, we'll see where we go from here.

[edit]Oh, you want the new stuff to be in the same form? Create a Panel in the form, put your controls in the panel and hide the panel. When the user clicks on a button, show the panel.[/edit]

yeh i want that on the same form...
but i am bit confused here,
1.) ok i dragged the panel
2.) now with in that panel i can add whatever functionality i want in the sub form..
3.) now i add button in the main form outside the panel...
4.) and i hv to call the panel with that button press....
is that right wt i said above or i am taking it wrong way. also can you tell me what exact code should i write to call panel...
thanks for reply...

Sounds about right. If your panel is called "panel1", then panel1.Hide() hides the panel, and your button click would call panel1.Show()

The best way to do this is to design your sub forms as controls, put them all on the form, and change the visible property to change which subform you're seeing.

What was trick to change inheritance to something else... design all like form than change what it inherit and it become control we can add to form actually?
|

Inheritance doesn't play into it. You just create controls, which have public and private members, and probably delegates, so that the form that consumes them can subscribe to events and show/hide controls as needed.

OK I got it... this is part I found here:
Do a normal form, then when you happy, happy with it, change inheritance to usercontrol. And that does the trick.
Must try that out... so basically I design normal form, than just change all to control and and I can put it on form like it's normal thing not other form.
Is this OK method to do this thing?

Thanks for reply.
But what do you exactly mean by "design your subforms as control". is there any article discussing this issue or if you could elaborate it lil more then it would be great.
Thanks

I mean instead of designing a form, create a user control and design the form on that.

I have a menu control on a master page that is attacted to a sitemap that is large. There are 236 items in the sitemap and it's about 52k file size. When I change content pages, there is a 2 second delay for the menu to refresh (reload). Does anyone have ideas how to make the faster? I realize that the content page is a "new" page so the control must reload. Maybe I shouldn't be using a master page?
in example, I have 2 aspx content pages based on 1 master page with a menu control on it. When I click from one content page to the other, the menu takes about 2 seconds to load.
I've tried putting the menu control on a custom control and caching it but that doesn't gain me anything since the other context page is a new page.
Thanks, Jessica

Is there a Whirlpool class in .NET?

A what???
I take it you're talking about the Whirlpool hashing algorithm?? No, there isn't. You have to implement it yourself. You can find a Java version here[^] and convert the code.

hi,
i have a problem concerning thread syncing with a manualresetevent. my code looks as below:
//this is a part of the callback of a receiving thread, qpt never gets null
//messageReceived is a manualresetevent
string qpt = myString.Substring(0, index);
Queue.Synchronized(this.Messages).Enqueue(qpt);
messageReceived.Set();
//and this is the code of my main thread, waiting for messages arriving in the queue
if (Queue.Synchronized(this.Messages).Count <= 0)
messageReceived.WaitOne(); //really waits (commented the .set)
Monitor.Enter(this.Messages);
string curLine = (string)(Queue.Synchronized(this.Messages).Dequeue());
messageReceived.Reset();
Monitor.Exit(this.Messages);
//...doing something with curline
when dequeuing, the element count is still 0. why? the queue isnt used anywhere else and it works with
while(true){
if (Queue.Synchronized(this.Messages).Count > 0)break;
}
instead of waitone (but takes 100%)
it seems that it takes a while until the queue recognises its new elements (does work with waitone if i place a debug point at waitone and always press play...). i also tried different combinations of monitor.enter, Queue.Synchronized with same results.
any ideas?

The Synchronized method returns a new synchronized Queue. Create it once and reuse it instead of creating it over and over again.
|
|

I dont agree.
The following code snippet gets three strings out of the queue
before it generates an exception:
Queue q=new Queue();
for (int i=0; i<3; i++) Queue.Synchronized(q).Enqueue("item"+i);
Monitor.Enter(q);
for (int i=0; i<4; i++) {
log("Count="+q.Count);
string s=(string)Queue.Synchronized(q).Dequeue();
if (s==null) log("<null>");
else log(s);
}
Monitor.Exit(q);
For me the synchronized queue works just fine (either with or without the monitor stuff).
