In my application, I have a task which is running on a background thread. I need a notification in the background thread when ever a MessageBox or any modal dialog is displayed in the UI thread.
Though I can do it manually by calling some function before displaying the MessageBox, but it will be great if I dont have to.
For e.g.:
backgroundThread.MessageShown();
MessageBox.Show("Task halted!");
I am guessing there might me some message which can be hooked on to. Even in the main GUI thread, is there any message/event that get fired just before a modal dialog is shown?

Why should a task that runs on a worker thread need to know of it every time a message box is shown in the UI? This sounds strange to me. Perhaps there is a better way to do it, but only if you explain what you are trying to achieve.

Okay, here is the requirement. I have some tasks which are done on the UI thread, and I have to show progress on a separate dialog, which is been shown on a worker thread. I understand that it should be the tasks which must be done on worker thread, but the current scenario cannot be changed for the time being.
Every thing is working fine, except for one glitch - if a message box is shown in the UI thread, it gets hidden below the progress dialog. So the user never gets to know that UI is waiting for an input. I need a way to get notified that a modal dialog box has been shown and I should hide the progress dialog.
Right now, I have to hide it explicitly just before every call to MessageBox.
I hope that explains.

The NULL DeveloperI have some tasks which are done on the UI thread, and I have to show progress on a separate dialog, which is been shown on a worker thread.
This defeats the purpose of a worker thread (because it cannot happily do its work on the background), and defeats the purpose of having the main thread as an UI thread (which is a thread with a message pump and you have blocked it with some lengthy processing). Blocking the message pump is just atrocious.

No! The glitch is that you are blocking the application's message pump. Just please have the worker thread do the lengthy processing and let it also notify the UI of the progress.

Rajesh, I fully agree with you, as I had mentioned and as I had said, this scenario cannot be changed because these are already existing applications written that way. And that application is HUUUUUGE!
So I had to do it the other way.

I agree with the others that the design is flawed but you seem to be aware of that.
You could wrap the message box call into your own static method with the call to the backgroundThread and MessageBox.Show, and call your method instead each time.

Dave, that will serve the purpose for MessageBox only. What about existing custom modal dialog boxes?

The NULL Developerand I have to show progress on a separate dialog, which is been shown on a worker thread
So you're saying that the progress dialog is launched by the background thread instead of the UI thread? If so, there's your problem. ALL UI, including the progress dialog should be created on the UI thread, not a background thread. You can invoke a method from the background thread to update the progress bar. If you can't change this, you're pretty much screwed. There is no notification your app is about to create a new dialog.

The CBT Hook is what would be looking for but it's a huge overkill solution to the problem of showing the window on the wrong thread in the first place.

I agree with Rajesh. This sounds like a very bad design to me. What are you ultimately trying to achieve with this?

Hello,
I just performed 8 searches on CodeProject for "Rich TextBox Ruler" because I want to add a ruler to my text editor project and, I also changed the search phrase around but it kept on showing "No results" page but the other day there were heaps... Does anybody know how I can add a ruler to my text editor project, or know any links for articles?
Thanks all,
jason

hehehe, I'm not sure of the correct name for it, but I'd like the same type of "ruler" as you would see in Microsoft Word, for example.

Thank you both for your links. Just what I was looking for. I'm very happy!

P.S. Maybe I need to reset my cache... I don't know why searches are not returning any results.

Can anyone explain why the following won't compile and a possible solution...
string strSequence = (view.GetFocusedValue().ToString() == String.IsNullOrEmpty ? view.GetFocusedValue().ToString() : "");
I get the following error...
Error 16 Operator '==' cannot be applied to operands of type 'string' and 'method group'.
Many Thanks

String.IsNullOrEmpty is a method, not a property. Try to use this instead:
string strSequence = (string.IsNullOrEmpty(view.GetFocusedValue().ToString()) ? view.GetFocusedValue().ToString() : string.Empty);

Trust me, having if conditions that change variable contents is a good way to really mess your code up and cause such nasty bugs! I don't think Empty() does quite what you think it does...
