I've looked at Skater .NET Obfuscator by RustemSoft in the past, and it works well. I've had it crash Reflector when trying to pry at my obfuscated code.

you could try mixing it up a bit. i'm trying diamond binding (dunnchurchill.com) at the moment (some guy on here suggested it recently), which takes care of the data-end really well. seems to be based on nhibernate - and you can do custom mappings manually using attributes. it doesnt do the gui side though, but i've found the data layer it creates is really clean, so you could use whatever tool you wanted (i'm just using the inbuilt databinding in VS). not sure if anyone can suggest a good business object to gui framework?

I typically use Application.CommonAppDataPath to store the global configuration files. Regards, Tim

Sorry for long time no answer, I am still in time-tracing business :) Loading icon from external file (plain .ico) takes near no time. Loading it from the dll's resources takes 4 seconds. The same situation is with any other bitmap. I am sure it is my mistake but question is WHAT'S WRONG?

I have downloaded and tried CLR Profiler from Microsoft, however it doesn't work with my project. I run the CLR Profiler, loaded and started my app and bang - the profiler shuts down without any message. Have you noticed such kind of behaviors? Hubert

Yes, it's great solution. Pricy and heavy, but it's a standard. But I meant something lightweight, handy and easy to use but thanx for your answer h.

Hi I think, the problem is inside COM - maybe something is missed or incorectly declared, but I have no access to the source :-(. There are also more types in this namespace: DokumentHaMag (interface derived from IDokumentHaMag) and DokumentHaMagClass (derived from DokumentHaMag interface). When I try to create new object of class DocumentHaMagClass, another interesting exception is thrown: "Query Interface failed for object x" (I don't remember exact text of this exception - I have no access to the compiler right now). Another interesting thing is creating RCW. I've tried to create RCW based on tlbs and dlls. Doing this in Visual Studio works well, but when I try to use tlbimp on CDNAX tlb, exception is thrown: "An element with the same key already exists in the Hashtable." with some GUID value. I'm gona try the tool you linked, it may help me to find the problem. thanks for your reply h.

yeah I had a hard time with this also. The datagrid reacts by the underlying data source having its OnListChange event fired. This forces a refresh of the data for the grid. You might try on either the change or leave event raising a changed event. This could possibly help in your situation. I'm a few days from this same situation in my app, so either way I will have to figure it out. nick I'm not an expert yet, but I play one at work. Yeah and here too.

It works! I was sure it'll be easy. Thanks h.

You're right two times in one answer: 1. This problem is REALLY annoying. :o) 2. This method works well - I have tested 3 different binding modes. There is just one small thing - it needs two more clicks on checkbox to "synchronize". Should I open the row for editing? I have tried to use BeginEdit() method on current row, but there was no difference. I think, that may be a point, but have no idea how to solve it. Thanks for help h.

hm, well, both of the above articles/codes are pretty good (and useful for other parts of my project) but it is still not what I've meant. But... in the meantime, i have made something which realizes my functionality - it is pretty simple now, but tomorrow I'm going to apply it to my project and test. And maybe I'll write a little article about writing my own DataPanel... Thanks very much for help and (again) for interesting links above H.
