There's a bug in your code. It surprise you to learn that we can't see your screen.
-
You don't need to know about paging or segmentation. You need to learn how to allocate memory and then only access addresses within the memory that you allocated.

How to register a shell property sheet for a single file type?
David Heffernan replied to FPiette's topic in Windows API
Rather than writing code, just edit the registry manually to debug your problem. Once you know what the solution is, then write code. If you want somebody here to troubleshoot then showing registry structure is much easier to work through than Delphi code to write registry values. -
@milurt Is this question too hard for you to answer? I think that the answer is 4, but you seem to think that the answer is 3.

Escaping UK pound sign in JSON
David Heffernan replied to david_navigator's topic in Algorithms, Data Structures and Class Design
Do pound signs need to be escaped in json? Please tell me you are using Unicode. -
Is it possible that an exception does not inherits from Exception class?
David Heffernan replied to Wagner Landgraf's topic in RTL and Delphi Object Pascal
Sounds like the worst of all worlds. The noise of try / except blocks everywhere, and old school checking for errors at all steps! -

David Heffernan replied to Wagner Landgraf's topic in RTL and Delphi Object Pascal
Don't you just have a small number of top level exception handlers? -
Best Practice Question: Bidirectional EXE-to-EXE communication
David Heffernan replied to Alexander Halser's topic in RTL and Delphi Object Pascal
Polling on a timer. Nice. As I said. The worst possible solution to this problem. -

I've used memory mapping for sure. But it sucks for this application which wants messages. Important to use the right tool for each job. -
How to remove metadata from Word document (using OLE)
David Heffernan replied to Kevin Smith's topic in General Help
Process the XML directly. Should actually be a really easy job for a SAX based processor. Even better, you don't need any COM automation of Word. If you need to do this in your product then I guess Delphi is best. If it's a helper script for personal use I'd do it in Python or similar. -
How many items in this list: 0 1 2 3 I think there are four items in this list, but the logic in your code would conclude that there are three items in this list. Therein lies your problem. Of course your real code may be completely different to the code you showed us in which case who knows what's wrong with it.

Ugh, this has to be the worst possible solution -

FWIW there is registration free COM. Not saying that's what you need, just that you don't need registration to use COM. -
How to register a shell property sheet for a single file type?
David Heffernan replied to FPiette's topic in Windows API
Reluctance to simply follow the documented steps is very odd here. -

Indeed -

David Heffernan replied to Wagner Landgraf's topic in RTL and Delphi Object Pascal
Its simple to check this by changing the code to handle all exceptions, not just ones that derive from Delphi's Exception class. I wonder, how would a language exception raised by another module in your process appear as when it reach your exception handler? -
I don't really see that this is so. Don't you want fast compilation and fast executable code? I'm sure you do. Do you think that you can have one but not the other?
-
I don't see why there should be compromise. I want great tools and efficient code output.
-
It's entirely possible to have a compiler that is fast during development / debug builds, but takes more time to optimise for release builds. So much Stockholm Syndrome in Delphi-land!
-
Binary compatibility for packages isn't something that bothers me. I mean, you get a major new upgrade and that happens anyway. But better code gen wouldn't mean changes to binary compatibility for packages. Also is 11.3 even binary compatible with 11.2 packages? Why do I want a single pass compiler? I'm not the end user. I want to deliver a program that runs quickly. Am I going to tell my customers, I don't want to deliver a program that runs twice as fast because then I wouldn't have a single pass compiler. Why do my customers care about single pass compilers? Is that something that your users talk to you about?
-
Frustration at my dev tool lagging behind. The editor is the least of my worries. It's the poor and never changing performance of the code emitted by the compiler that frustrates me the most.

Is there a way to use a platform specific win32/win64 DEF file?
David Heffernan replied to alank2's topic in General Help
What about for your 64 bit compilation? -
I guess my sarcasm didn't shine through

If only other editors had this feature

The fact that you have a different workflow from me doesn't mean my workflow doesn't exist
