In case you have home-grown components, I assume you have done basic leak checking on those. Not freeing stuff after use can quickly escalate memory usage for database objects. Learned that the hard way.

Using Process Hacker can give some insight into which modules are loaded and what kind of allocations are done. .

Does any of the forms open potentially really large amounts of data?

Well, the point here is not disabling RAD as such - but to try to determine where the memory goes. That said - I stopped doing RAD years ago and swear by setting things up in code. Got fed up with lost property values and event handlers after code merge blunders.

Is it mission impossible to disable the data links on forms when not working on them? It would probably mean that you need to add code to activate the connectivity at run-time.

Are there a lot of forms that have design-time data connections?

When BDS reaches 1.5Gb - you are usually in an out-of-memory situation, and BDS will behave erratically or most likely not at all. The question then is - what is eating your memory? Are you building multiple projects in a project group?

Are there any files in your projects that are on a network drive?

This could use a QP to expose it in the regular Options dialogs.

What about setting Owner/Parent of the children to nil? (I am just throwing pasta at the wall here now)

One alternative could be to have an permanently invisible main form, so that the perceived mainform also is a child?

I am trying to remember if I've seen this done in any app before, but I am coming up short? What happens to child windows if main window is set invisible, I wonder?

Have anyone done an article on the current pitfalls of inline variables?

The point of making a second class was to enable one of the features that Mike was looking for, i.e. hiding implementation details. The single set field was a single property of the single example Mike initially gave. He later pointed out there are at least four different methods of operation, even adding three-way comparison/merges, meaning you need a third file parameter. You can put these classes in separate units and have a factory method or class that instantiate the specific inner classes, and completely isolate the inner workings from the outer use, offering f.x. two compare methods. function Compare(const aFileName1, aFileName2: string; const aMerge: Boolean = False):TResultType; overload; function Compare(const aFileName1, aFileName2, aFileName3: string; const aMerge: Boolean = False):TResultType; overload; Again, just a simple example based on the limited insight into all the possible variations of parameterization. There is more than one way to solve such a challenge. I chose to use polymorphism and encapsulation.

Please elaborate. How is it worse? How would you solve it?

I like streamable objects. That makes it impractical with params to the constructor. Hence, I try to avoid them.

Having arguments to the constructor is something I try to avoid. TINIComparer = class private fINIFileName1: string; fINIFileName2: string; protected procedure LoadINIFiles; procedure CompareINIFiles; virtual; public constructor Create; virtual; procedure Compare(const aINIFileName1, aINIFileName2: string); end; TIniComparer2Way = Class(TIniComparer) protected procedure CompareINIFiles; override; // if necessary public constructor Create; override; end; constructor TINIComparer.Create; begin Inherited; end; constructor TINIComparer.Compare(const aINIFileName1, aINIFileName2: string); begin fINIFileName1 := aINIFileName1; fINIFileName2 := aINIFileName2; LoadINIFiles; CompareINIFiles; end; constructor TINIComparer2Way.Create; begin Inherited; fCompareType := cmt2WayCompare; end; // from main form: fINIComparer := TINIComparer2Way.Create; fIniComparer.Compare(edtINIFilename1.Text, edtINIFilename2.Text)

There are various ClearXxx methods for TFDMemTable, but it is not obvious which one(s) to call, or in which order, and if they actually reset the whole thing. The above suggestions, on the other hand, are solid.

Free/Create ?

This one redirects: http://welcometothe.中国

I see many Norwegian sites simply do a redirect on the IDN URL to a non-IDN version of it. As for Chinese - here is a slew: https://www.101domain.com/chinese-simplified_idn_domains.htm Edit: Err... where you can register a slew

Hmm... Wasn't these installer modules - i.e. .msm files? What about PowerShell> Get-ChildItem 'c:\program files (x86)\' -include BDE*.ms* -Recurse

I can't find anything BDE but those Delphi version specific variants of the one you mention in my registered user downloads. Have you tried crawling all of your disk for BDE*.msi ? PowerShell> Get-ChildItem c:\ -include *.msi -Recurse I suspect adapting to FireDAC may actually be easier than fighting with the ancient BDE.

I try to ensure that all my text files have a BOM and are encoded as UTF-8.
