Hi guys, I find (especially in .NET 1.1) that many UI type classes are kept "sealed". Any specific reason for that? Examples: Classes like Tooltip, Progressbar etc. Typcially, UI classes are supposed to be extensible. I can understand if 3rd party vendors keep their UI classes sealed (for more business oppurtunity ;-)) and therefore only provide developers to extended the functionality by providing properties or other extension mechanisms like interfaces on the controls/components (for custom rendering of the component) etc. But why would Framework providers like Microsoft, keep their (of course, not all!) UI classes sealed?

Ahh! That explains the fear! Thanks. :-)

"That way, you can play all you want safely without screwing up your production environment." Why??? Is .NET 3.0 not RTM'ed yet? It is RTM!!!!!! I would be worried only if it was a RCs or Betas, but with RTM release, MS should ensure that it does not screw up any production environment, especially the .NET 2.0 system. If they cannot assure that, they should not be releasing .NET 3.0 as RTM at all. They should keep it as Beta if the developer community will have to be cautious to use it in production machines running 2.0 framework (or use it via Vistual PC etc.).

"However, we will not support Visual Studio .NET 2002 or Visual Studio .NET 2003 as development environments on Windows Vista." Does that mean we cannot build .NET 1.1 apps in Vista. It has to be only 2.0 applications, since there is no way to build 1.1 apps with VS.NET 2005.

I would return null, since String.Empty could be a valid string for the "caller", but a null object is "typically" not and i would expect the caller to handle "null" value returned by a called funtion (good practice).

Cheers, yes I wanted a website URL (I should have been specific about this, sorry!) to post bugs on .NET Framework 1.1. Also the link to VC# express site may not be helpful (i am not too sure though!) since i have this bug specifically on MS.NET Framework 1.1 :-( -- modified at 7:18 Tuesday 30th May, 2006

Hi All, I want to report a bug in the .NET framework. Any idea how to do this. I know ther eis this support.microsoft.com site. But it looks like it needs a MSDN / Product paid subscriber ID or a payment (via credit card),etc, even to post a generic bug report. Is there any other way to raise a generic bug rreport on MS product, specifically .NET framework 1.1, so MS can take a look at it?

Hi There is a Usercontrol which is displayed in the modeless state. Now i display another Usercontrol on top of the the other control and the other control is now completely invisible (it goes behind the new one i have shown now). The invisible control has a a button control in it and it has a mnemonic set so that upon a particular key press, it will fire its Click event code. Now when the user is currently working with the new Usercontrol that is displayed on top on the old one (which is currently invisible, but it is there), and hits a key, say "J", the old control's button control's click event gets fired. This is because the key "J" is its mnemonic. How to ensure that when that Usercontrol is not visible, the key down hit is not consumed by the hidden usercontrol's button control. and is used by the one on top - i.e. the new control. I hav tried all sorts - OnVisibleChanged(), OnLostFocus() etc where i tried to remove hte Click event handler from teh button's click event and adding it when the control becomes visible, etc, but these do not work. I think the only way to do that is to do something in hidden control's WndProc(). Any ideas?

Actually, if you use XenoCode and ask it to embed the .NET framework, it will embed it in to your applciation codebase (binaries), so you don;t have to ask your customers to have .NET Framwork installed.

Hi all, I had recently placed an order for VS.NET 2005 + MSDN professional, and its been a week since i had made an order (in the UK) and the reseller tells me that they are struggling to complete teh order because of a big queue in Microsoft on the orders placed. In fact, i did not even order for a boxed product, all i ordered was a open license stuff, so all i will get to start with is a MSDN regsitration stuff where i can go in and download the purchased products. But still it seems to be a big problem with Microsoft to complete the order, the reseller tells me. Anybody else facing similar problems, especially in the UK? -- modified at 12:21 Monday 28th November, 2005

Thanks Roger. Your message is too cryptic :-) No disrespect meant here - anyway - are you trying to help me with some information here or are you just simply teasing my spelling mistakes in my post? regards.

Hi Guys, I am evaluating "Wise installer solution 6.1 for windows" for my .NET applications. I am unable to find anyinformation on these two specifi points. Anybody out there with any ideas for these Questions, please help: 1. I am installing a shared assembly fro teh Wise installer package (MSI package) using hte GAC folder and adding shared assemblies to it. It installes fine. For a paritcular reason (my apps specifi needs), i will need to clean up the GAC download cache when uninstalling my application (using Wise 6.0 produced .MSI file). There does not seem to be a way to do it. I know I can run "gacutil /cdl" to do this, but i don't want to have any custom actions in my MSI package. I want the installer to do this for me via some feature set or some property setting. Is there a way to do this?

Hi I have a interesting question. When we buy a .NET controls package with source code and learn from it the way to develop professional controls and we want to write our own control for commercial sale, would it be a legal issue? Assume in the above scenario that I buy a control with its source code and i learn how real professional controls are developed (as a learner). Then I get some more ideas of my own and want to write a control from scratch, maybe the control I am planning to write carries the same functionality of the one I purchased, but i wrote it from scratch with my own ideas and functionalities, and sold the licenses commercially, would the seller of the control I purchased earlier, have any right to create problems for me with the sales i am making out of the control i wrote (all from scratch)? You can assume that: 1. I only learnt how a propessional control was to be written 2. I start writting my new control from scratch with no referece to the one I purchased, whatsoever. Any ideas?
