Is it really wise to use strongly-typed datasets?
I've been mulling this question since I started using .Net in 2003. Seems
like a lot of effort to rearrange code to get the data layer out of the UI layer. It seems like a nice quick-and-dirty solution, but long term, is it really the wise thing to use drag-drop dataadapters?? |

Re: Is it really wise to use strongly-typed datasets?
Earl,
As long as you drag them on a component instead of a form (UI) there is no any problem in 2003. A pity is that the most samples are draging them on forms to show how it works and that is than taken as how to do. This concept is not any more in version 2005.

Re: Is it really wise to use strongly-typed datasets?
The drag and drop stuff paints you into a box. Whether that box is good or
bad depends on your application, your coding style and standards, etc. In 2005, you have TableAdapters. They work very similar to many of the code gen products out there. Unfortuantely, they do not automagically set up multi-table DataSets to auto-update. It could be done, based on dependencies, but you will have to control this ... for now. Useful in Enterprise Architecture? Sure, why not? As for getting the data layer out of the UI, I am not sure what you mean. If you mean the "all in one" objects in .NET 2.0, I agree with you. Can them. If, instead, you are setting up your layers and using drag and drop, there is no problem. The DataSets are set up as components, which allows you to add to UI. The TableAdapeter makes things easier in some respects and harder in others. I am not sure I am completely shot in the butt with them, but you can still create bindable components no matter how you are filling the DataSets. In short 1. There is nothing wrong with DataSets 2. THere is nothing wrong with drag and drop, but you should understand what is going on underneath the hood 3. I personally detest the "all in one" data objects. Your mileage may vary. :-) -- Gregory A.

I hope you have 2005 than you can try this one. http://www.vb-tips.com/dbpages.aspx...82-b1ed16424252 If you have 2003 than reply Cor "Earl" <brikshoe@newsgroups.nospam> schreef in bericht news:%23nj8Nfm1GHA.1040@TK2MSFTNGP06.phx.gbl... > Cor, > > Please show me what you are talking about. > > > "Cor Ligthert [MVP]" <notmyfirstname@planet.nl> wrote in message > news:ORUsRBi1GHA.4108@TK2MSFTNGP04.phx.gbl... >> Earl, >> >> As long as you drag them on a component instead of a form (UI) there is >> no any problem in 2003.

Re: Is it really wise to use strongly-typed datasets?
That's really the sort of drag-drop thing I'm trying to get away from. Do
you know of an example that does this with a component vs. a form?

Re: Is it really wise to use strongly-typed datasets?
What would the difference be? Does it matter if the example shows drag and
dropping onto a form vs. a component? In the end, you are still drag and dropping these objects and using the wizard - exact same thing.

Re: Is it really wise to use strongly-typed datasets?
Earl,
Exactly as Marina says, however the advantage is that you can use the created component class in all your forms as a kind of data acces layer.
