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
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 ??

Maybe I'm missing something, but if you create the controls dynamically, you have the properties available to you?
How are you adding them to the form?http://www.rocksthoughts.comhttp://www.jumpstarttv.com - Free Technical Videos!
the controls are being created in a loop.

This library violates Delphi's license (redistributing of RTL/VCL
source files is not allowed).
The last post was deleted and I'm sure this one will be deleted, too.
