A declaration of an alias, anyway.  TMyClass and TAnotherClass will be the same type, as far as the compiler and RTTI are concerned.  Now, if you do this instead:

TMyClass = type TAnotherClass; 

Or this:

 TMyClass = class(TAnotherClass)

Then TMyClass will be its own unique type.

Thanks! I think you're completely right and off-topic to the question. 🙂

The first is a class reference (metaclass), the second is a type declaration (class).

Simple assignment to Content should be sufficient:

Response.Content := doc.XML.Text;

This will both encode the incoming string value and set ContentLength automatically. (See TISAPIResponse.SetContent in Web.Win.IsapiHTTP.)

In your case the encoded stream was longer than the original text, e.g. due to insertion of escape characters. By setting ContentLength explicitly you have effectively truncated the encoded stream.

Also see Sysinternals sdelete -z:

DUnit for Delphi, fpcunit for FPC, one source code for the tests as they are largely compatible, you only need to conditionally compile with the right uses clause.

There's an example of that in chakracore-delphi.

I don't think 'injecting code' is the best way to go.

SetWindowsHookEx is one of the ways of 'injecting code' on Windows.

Documentation: " SetWindowsHookEx can be used to inject a DLL into another process."

Actually I disagree, sorry.

I apologise, no flame intended 🙂 Was that a reply to me? It's not terribly important - but do you disagree with the fact that the code was posted in 2009? 🙂

Just curious. I wish you a nice Sunday. 🙂

unfortunately the code @Dave Nottage referred to does not work.

I'm not surprised - it's 10 years old. 😉

Some pointers can also be found here.

I would guess probably something from ComCtrls.

In case the blue ball image is linked into one of Delphi's binaries as a resource it might be possible to use a resource editor  to replace it with your own.

It should also be possible to use branches and commit, according to their article: Support for Subversion clients.

But this requires somebody with authority to do the initial slapping.

In case of lack of authority, proceed with slapping until the desired level is achieved. 🙂

Hi all...

 

did you ever see when the stackoverflow thread was written?

 

The question was posted Dec 24 '15.

The quoted answer was posted 20 hours ago, deleted 2 hours later.

If you chose the code-generating wizards route perhaps this might (still) be helpful:

• old article (web archive): OTA: Visual design of Wizards
• code: https://cc.embarcadero.com/Item/17106

Couldn't reproduce here, Delphi 10.3 Update 1, Version 26.0.33219.4899 - seems to work as expected

An easy way would be to create and use a data module, then you can put your Indy components on it and use the IDE designer to write your event handlers.

This is really helpful. Can I ask, what is the resource editor you're using in the screenshot?

Looks like Anders' Resource Editor which you can download from his website: http://melander.dk/download/

what options are there in Delphi for an atomic test-and-set or incr-and-return-value operation?

System.Atomic* routines (e.g. AtomicCmpExchange)

Just curious: Has anyone seen a valid use case for defined ordinal values in enumerations?

Not really when writing my own code, I try to avoid them if possible.

Sometimes for interop with an API, e.g. when translating C headers where enums are already declared that way.

Or when you need to support a binary format which uses some specific ordinal values, then it depends - you might still prefer to use an enum but avoid conversion.

No reservations, I find it concise/elegant and prefer to use it whenever I can. My 2c.

You might have to avoid enum types with explicitly assigned ordinal values, though.

On a totally unrelated matter I would like to direct your attention to a completely underrated feature of Delphi: LiveBlame - in the IDE!

 

This however works with hg,git and Subversion. But I just love this! I love to put blame on others, and then find out it was my fault after all! 😄

 

People have actually asked for blame as a feature, that's why I included it back then in delphisvn (before it became Version Insight).

I find it useful myself to see who committed which lines and also when. This piece of metadata can be useful when trying to understand a code base and its evolution.

Thanks,

 

Can't see any difference but if I copy record and external method declarations from github, it compiles. weirdest thing ever 😄

Just a thought... Sounds like the units in your uses clause are listed in a different order so the type declarations resolve differently.

I see nothing wrong in that, but I just can't see why Compiler does not like it. It might be something trivial, but I just can't figure it out.

 

TMenuBarInfo = tagMENUBARINFO; // <- [dcc32 Error] : E2029 '=' expected but identifier 'TMenuBarInfo' found

 

 

Sorry, I've been vague. Here's the full code which works in Delphi XE, I hope it helps:

GetWindowMenuItemRect example

Cheers!

On Windows, there's GetProcessTimes API if that's what you want...
