Vb net label not updating
Okay, I tried both of those tricks, the label1.invalidate and the thread.threading.sleep() (one at a time). The code still executes the same way: A long pause, and then the last text shown. I'm starting to think that I'll have to have the user step through the code using multiple "next" buttons, which would be much less elegant.
(this uses the API call "Sleep" to insert a pause, declaration not shown here) Any thoughts? If I have misunderstood you, please feel free to let me know.I suggest you handling this issue using Java Script. you can use update panel and put your control in update panel and after finish the loop call updatepanel.update() for() Updatepanel1. Update() End Sub @chankc2005 - You really need to look at the client side Java Script code that @Shengqing Yang proposed as the solution to updating your label with each subsequent number.

Setting the Text property will already have invalidated the appropriate area of the control, so calling Invalidate again is pointless and calling Invalidate with no arguments is wasteful. Is it because the entire application sleeps, and not just the thread? The best however is to design your application in such a way that you don't need to call it on the UI thread at all.
Also, am I correct to infer that the timer_tick event is the action which occurs when the timer has expired its interval? @ dbasnett & pradeep: Why is using a timer to keep track of time a bad idea, and why would threading.thread.sleep(1000) not be good for an application? Do Events might give it some time to refresh the GUI in between.
It is a bad idea for situations where you need a very high precision timer. So you can continue to use the timer the same way you used in VB5/6. Besides executing you code, the UI thread also has the responsibility of maintaining the GUI. "A problem well stated is a problem half solved." Charles F.

Timer is not a bad idea for normal application use. Sleep on the UI thread is a bad idea because it will hold the UI thread for that specified interval of time. So your screen will not refresh for 1 second if you call on UI thread. So you do your work on secondary threads and let the UI thread do what it is really meant for.
I'm having trouble with getting labels and text boxes to change in VB2005.
A sample code snip would be Which should make Label1count upwards at one-second intervals.
When I run the code, however, Label1shows "Zero" for five seconds, then says "Five" when the subroutine ends.
