Create DataSets dynamically (at run-time)

I've seen some code samples that look a lot like my D2007 Enterprise code, but mine dies on the last line:

var TempDataSet: TADODataSet;
TempDataSet.AutoCalcFields := False;
TempDataSet.ParamCheck := False;

Why can I set one property and not the other?  I also tested with setting the Connection property on that line, and it yields an access violation too.

That should be:

TempDataSet := TADODataSet.Create(nil);

Thanks so much for catching that.  Don't know how I overlooked that so many times.

Dynamically creating an object at run-time
Hiya! I have an interesting problem that I have been unable to solve. If anyone has any advice, I would be (almost) eternally grateful. Here is the situation: On a window I have a datawindow control (dw_original). I wish to dynamically create exact copies of this datawindow control at runtime. The number of these copies is not set, but is determined based on user actions. I assume I will have to create some sort of array to store the object references, but how do I create the objects? The data object is an external datawindow, so I don't need any transaction object for it...

Dynamic Run-Time Analysis of Delphi apps?
What tools or methods do people use to do dynamic run-time analysis of Delphi apps these days? There used to be some tools that would parse the source code and add Trace statements to all of your functions so you could figure out the run-time call graph and do execution timings. But I can't seem to find any. Ideally, this would be a compiler switch that would work in tandem with some specified classes to capture run-time data that could be analyzed later. At my present job, we have a rat's nest of DLLs, and it's ridiculously time-consuming to track down the source of erro...

getting dynamically created control properties at run time ?
In my C# webform I am dynamically creating few controls. How do I retrieve the properties of all those controls at run time ?? One of the handler of click event of a button needs such information.

How are you adding them to the form?http://www.rocksthoughts.com - Free Technical Videos! the controls are being created in a loop. ...

Creating pages with dynamically created links using strongly typed datasets
