I was reading an article a few minutes ago here on CP that discussed how to host a Form designer. I do not have any particular use for it right now but I was curious. So I got it up and running, it works well and as expected. I began looking around on MSDN for the various things I could do with it, such as the various Service interfaces for the designer. Now I have run into a bit of an issue with one of these services.
I was looking for a way to be notified when a control has been added (via the IToolboxService I created). The only thing I can find, which may be the incorrect method and someone please tell me if so, is the IDesignerEventService. It has events like "ActiveDesignerChanged" and "DesignerCreated". So I figured I could hook the "DesignerCreated" event up and remove the IToolboxService when that event is fired. Here is how I did it:
IDesignerEventService evt = designSurface.GetService(typeof(IDesignerEventService)) as IDesignerEventService;
if (evt != null)
evt.DesignerCreated += new DesignerEventHandler(evt_DesignerCreated);
However, "evt" ALWAYS has a 'null' value, therefore never being able to receive the desired event. Anyone have an idea why this is happening? I have hooked up other events with no problem but this one is being a PITA. 
Thanks in advance!
------------------
SOLUTION:
As far as receiving events, I went with Pete's advice and I implemented "IComponentChangeEvent". In order to load/save the form design I was able to "decipher" the article I was reading. This is the article on MSDN. I am close to completing my little test that I have been working on in order to learn more about the subject.  Thanks again!

OK, a couple of things here. First of all, you really should get the design service from IDesignerHost service. Basically, this is responsible for the lifetime management of designers, so is the appropriate place to get an instance of a designer from.
Now, onto the point of what you are trying to do. You actually need IComponentChangeService if you want to find when a component has been added or removed to the designer surface. Have a look at this[^].

Thank you for the information. That is what I was looking for. I appreciate it!
How about key press events on the designer? I have gone to Google for this as well, though with no luck.
EDIT:
Nevermind, I figured it out. I simply handled the "KeyDown" even of the application form and it works perfectly. Thank you for your help!

Excellent. Congratulations on this. The VS object model is a bit of a bitch to work with.

Yeah, that has become quite apparent in the past few weeks for me. I've been messing with a lot of it out of curiosity. Haha.

One more question. Do you have anything I can read which can help me out with saving the form's layout to a file for later use? I am trying to figure out how to save it and re-open it.

I don't I'm afraid. I come into this from the other side - from automating Visual Studio.

Alright, I will do some more digging elsewhere. I figured out I need to use a DesignerLoader. However, I am not sure how to implement it, as it is an abstract base class that you must derive from in order to provide functionality. I found a code sample but the code seems really unorganized to me. And the article (not here on CP) does not explain it very well.

I have a database design for logging errors including program name, method name, all parameters passed to the method, and all parameters passed in a database call.
We are using CommonLogging for some of our log calls that will bind to log4net for the log functions. I have read tutorials and documentation indicating I can pass individual fields that are custom to the program. But they are all for a flat logging record, not deep for posting parameters.
What I'd like to do is configure log4net to call a custom logger passing my parameters to it, and doing the database writes.
Does anyone know if this is possible with the log4net configuration or not?

If you need to provide interop between .NET and Java, I find that ikvm[^] is the best way to achieve this.

Looks interesting. Worth a mention in Free Tools?

i think he's trying to execute the javascript on the page, but the alert() on the page don't show up, so he's confused
i think the method he's using only download the html, don't parse or execute any javascript on it, but i don't know how to help him... 
I'm brazilian and english (well, human languages in general) aren't my best skill, so, sorry by my english. (if you want we can speak in C# or VB.Net =p)

psiProcInfo.ErrorDialog = true;
psiProcInfo.RedirectStandardOutput = true;
psiProcInfo.CreateNoWindow = true;
prcFFMPEG.StartInfo = psiProcInfo;
prcFFMPEG.Start();
ponse that I push the start botten that I tried to fix the code that I
inserted the logo in the movie with ffmpeg.
Is that be okay if I don't choose the path of logo.and Is there any something wrong that I did.

I can't give you any specific advice on your problem but as a general comment I would say don't try to automate an external program unless you know what the command line should be.
Do your experiments either directly from a command prompt or from a batch file so that you can observe the results. Once you have the external program working properly only then automate it's operation.
