Hi,
I've implemented low level mouse hook in my application to capture mouse clics, which is pretty easy.
But I've experienced great performace drop when moving windows when the hook is working. So I'd like to run the hook on a separate thread and I cant figure out how to do that correctly. The callback function gets never called thus the hook was created on a separate thread.
I've spend some time studying msdn however I still can't make it work.
thanx for help

You chose the hard way for me 
ok, at least I'll exactly know what I'm doing.
So I guess calling WaitMessage after creating that hook should help to create message quee on my thread?

Yes, and then all the mouse move messages from the UI created in that thread will go into the queue.

Sure, if you say so.

It's not possible the way you are thinking about it. What you can do is develop a solution by receiving the messages from the queue in the main thread and using your own implementation of inter-thread communications (there are many ways to do that like this one[^]) to pass the information on to the worker thread. Of course if you also require passing information back to the main thread ( like to display something in the UI ) you have to account for that as well.

I thought I can make it work running completely on separate thread. Otherwise it's not going to help me with performance. I have no heavy proccesses contected to that hook event, just simple things and still it doesn't perform well. But I have strong feeling that my performace lost is connected to mouse tracking over NC area, as I have implemented custom border painting which involves a lot of unmanaged API calls. I'll try to figure that out.
anyway thanx for help. I didn't think that you will provide me with a straightforward answer like this one

I can't possibly do that since I have no idea what actual problem you are trying to solve. You only posted what you think the problem is.

You already did by saying it's not possible. It's not really possible to post here all the code that it's used for the non-client painting, because it's quite a lot. However I can figure this out easily by removing that functionality to see if what happens.

To my big surprise, removing that custom painting and sizing code didn't help at all. Do you have any idea how could I make it run smoother? Just the simple act of creating that mouse hook causes the whole UI to run not optimally...

Sure there is no reason to hook mouse messages for the UI thread you are already running in yes? Are you creating a System Wide Hook? That would be even more expensive.

You really need to specify your functional requirements if you want to receive any help on this problem.

Yes I'm making system wide hook. Let me explain why I'm hooking mouse events. I want to be able to use context help system. That means, by holding a specified key (CTRL for example) and left-clicking on a control, help file rather than control OnClick event will be raised. So I need to hook keyboard for my special key (that is running w/o problems) and mouse hook to catch any lef mouse click on my application form surface (any control), run the help file (.chm scrolled down to that control found by key-name). Rather than overriding OnClick in any possible control that I will ever use, I decided that the mouse hook is easier way how to accomplish this.
dont worry about the NC painting anymore...

And one more question. When I want hook only events regarding my Application Domain, I need to call SetWindowsHookEx with my AppDomain.GetCurrentThreadId() which is unmanaged thread id. Now this method is deprecated and msdn states that I should use ManagetThreadId instead. But this id is not working of course. How can I avoid AppDomain.GetCurrentThreadId() and still create the hook locally (which signifficantly improves the performance)?

Hi
I am working on localization, and I was wondering if there is a tool from microsoft or other that can read in resource files and provide a view of the form with its controls placed and attributed according to the XML in the resx file. I presume what ever code that does this in visual studio is not available to the public.

I think you're missing the point of resource files. Resource files typically store localized information, e.g. text data that should change depending on the user's culture. If you want to render web forms based on XML definitions, you need to look at using XSLT to transform XML to HTML.

Hi,
I haven't seen the functionality you're talking about anywhere available, but I guess it should'nt be difficult to initialize those forms using reflections and display them...
Or maybe I would consider just creating picture of the form and display that picture. That would be much faster approach, however not dynamic...
I guess I didn't help much
good luck

Since I have only recieved flamebait replies (other than Zilo) so far, I guess I should clarify my original post.
I have multi-lingual .NET 1.1 (Visual Studio 2003) forms with resource files that have been generated. These resx files contain a full description of the entire form for the projects in question in XML. I would like to be able to render that information as a form, and possibly even have some form editing ability. This is quite possible to do, and I could code it myself but I would rather not due to time constraints.
Using WPF, and I have heard of it, is interesting but it is not helpful in my case since I have a lot of .NET 1.1 forms I need to localize and you can not simply drop in the 1.1 resx files into a xaml application definition file.

Agreed but raises a larger question. Who and why would someone or some team / shop decide to build a .NET 1.1 application without considering as part of the Project Life Cycle migrating it to future versions of the platform / languages? Just Curious, I mean what about this platform has not screamed PLANNED OBSOLESCENCE since day one? Just curious?  And just like Java I might point out.

To answer my own question, this program does precisely what I had asked in my original post. It loads resx files and renders the form, allowing a localization expert to create new localized resx files without having to look at the rest of the project.

hello,
i want to remove the selected items of listview, the code i wrote is working but too much slow
listViewEx1.BeginUpdate();
int count = listViewEx1.SelectedItems.Count - 1;
while (listViewEx1.SelectedItems.Count > 0)
listViewEx1.SelectedItems[count--].Remove();
listViewEx1.EndUpdate();
i also tried to remove items in this way :
listViewEx1.Items.Remove(listViewEx1.SelectedItems[count--]);
but no benefit, i have about 1200 items with only one column
any solution?

Try surrounding your code with calls to listViewEx1.SuspendLayout() and listViewEx1.ResumeLayout() methods so that your listview is not repainted every time you remove an item.
