I am using vb.net 2005. i am trying to set report groupings of a crystal report at runtime based on user defined options. MSDN says this:
Dim FieldDef As FieldDefinition
FieldDef =
Report.Database.Tables.Item(0).Fields.Item(comboBox1().Text)
Report.DataDefinition.Groups.Item(0).ConditionField = FieldDef
but error shows invalid group number
how to solve this?

There is a lot of chatter about the improvements HTML5 is about to unleash on the web development world. How will this new standard affect web dev frameworks like Faces, Struts, or even ASP.NET? How long will it take them to 'catch up' in order to emit such code? Will controls get deprecated?

Hello Guys,
We have been using PHP/MySQL for our web application which has been growing a lot, the database is around 4-5GB and one of the table is 2GB sometimes, hence slowing down whenever any queries to that table is called.
Should we just try to optimize, or are we using MySQL above its limit? Will switching our web app to .NET/MSSQL resolve the issues?
Thanks

I saw couple of SO questions (SO) concerning SQL-server. For SQL-server there was no decent solution. All were hacks/workarounds. What about Oracle? Is it same answer (Paremeterizing each value)? Any Oracle example without LINQ would be appreciated (I have .NET 2.0).
Thanks & BR -Matti
I would like to find out from .NET code whether DirectX 10 is supported on the machine, preferably without using managed DirectX or XNA assemblies.
Thank you in advance!
Rather a simple question. But the implications are vast.
Over the last few weeks I've been reading a lot of material about n-tier architecture and it's implementation in the .NET world. The problem is I couldn't find a relevant sample for Winforms with Linq (linq is the way to go for BLL right?).
How did you guys manage to grasp the n-tier concept? Books, articles, relevant samples etc.
First time I am bit disappointed in StackOverflow cause my http://stackoverflow.com/questions/2571727/c-concurrency-vs-java-concurrency-which-is-neatly-designed-which-is-better question was closed.
My intension was just trying to gather knowledge from programming guru's who worked in both the programming technologies. Rather closing this question, please help me by discussing what is good, bad, and ugly in multi-threading part in both the platforms.
It is also welcome, if someone would like to compare with .Net 4.0 with JDK 6 (or JDK 7)
Hi there,
I'd like to move publicly accessible files .css, images into my ASP.NET MVC Views folder. Since the Views has a web.config denies all requests, what exactly do I need to do to achieve this, so .aspx, .ascx are still protected while .css, images are accessible. Could someone show in detail please.
Thank you,
Ray.

Are there any .NET libraries etc. which allow adding layers (with text) to .tiff images?
Something like annotations, so that it would be possible to separate them from image afterwards.
I tried DotImage - it allows to add annotations, save them as embedded into image and load them afterwards, but no one other image viewer seems to recognize that they are there.
