STATUS BAR TEXT NOT UPDATED

Question

hello in my application i am updating the status bar text property many a times as the different part of code is executed. However i can see only the last update been performed. ex: textBlock1.Text =  Launching your application. please wait ...; /// some code textBlock1.Text =  i am ready !; // some more code here textBlock1.Text =  done !; output is :: done ! Is this because the updates are performed very fast?If so how do i handle this situation ? I want the text to stay for some time on screen before the next update. I tried : thread.sleep(1000); but looks like it is not the right way and it is not working. can anyone help me on this? thank you

Not my area of expertise but you can try InvalidateArrange or UpdateLayout. Ref:http://msdn.microsoft.com/library/windows/apps/windows.ui.xaml.controls.textblock.aspx#methods

[quote] well this Refresh() method is not available ! I am using visual studio 2010 [/quote] So what is the type of textBlock1? Is it a textbox is it a label is it a custom control is it a statusbar? According to MSDN the refresh() method is available for the statusbar from (at least) dotnet framework 1.1 onwards; ref http://msdn.microsoft.com/en-us/library/system.windows.forms.statusbar_methods%28v=vs.71%29.aspx from there you can check the newer versions

Vulpes: thanks for the reply. I got what you are saying but it won't help much to me.I am kind of conversing with the program. So in response i want the program to write few lines in status bar then i give some input and some other lines should be displayed.here only the last line is displayed that's the problem.

michel thanks for the reply. backgroundWorker class is for doing heavy work in the background isn't it? my problem is to just write a line in UI so that user can see where the execution is happening. I tried using separate thread but of no use. Is there a way of appending the text in status bar ?that is the old text remains there and new text line is just added to it. thank you

Vulpes · Answer

An easy way to ensure that a user ALWAYS sees any messages - and perhaps has an opportunity for remedial action if there's a problem - is to pop up a MessageBox rather than write the message to a textblock or label. The drawback of course is that the execution of your code is suspended until the user dismisses the MessageBox.

I would choose different approach and put that code on separate thread so the whole UI remains responsive. Leaving the application in not responding state is very bad habit imho. You can use the background worker for this that is extremely easy to work with. Here you can find more info about it: MSDN BackgroundWorker

You can try textBlock1.Refresh() textBlock1.Text = hi; textBlock1.Refresh(); System.Threading.Thread.Sleep(1000); textBlock1.Text = hallo; textBlock1.Refresh(); System.Threading.Thread.Sleep(1000); textBlock1.Text = done; textBlock1.Refresh(); System.Threading.Thread.Sleep(5000); Don't slowdown user experience because YOU want to show something; if the code is fast it is fast nothing you WANT to do about that.
