I just found out about DrMemory, which seems like an amazing debugging tool, if somewhat complex at first glance.
When I run it under Delphi with all debug options I can find, it stills says it cannot find line numbers and instead displays hex offsets into the executable.
Is there a way to have Delphi 10+ generate what DrMemory needs to provide line numbers?
Here's a link to DrMemory: http://www.drmemory.org/
Thanks!

sorry for my bad english, and sorry if my question not following the rules because this is my first question in stackoverflow.
I'm rewriting my internal office application which developed using Delphi but I dont have previous source code. For application reporting, i'm using the same FastReport .fr3 file from previous developer. But when i tried to print it out, it print out with different font. The Fast Report Preview before printing already same, but different after printed. Am i missed some settings?
here's the preview of the printed report:
my application report:
https://dl.dropboxusercontent.com/u/42816630/stackoverflow/my%20app%20report%20result.jpg
previous application report:
https://dl.dropboxusercontent.com/u/42816630/stackoverflow/previous%20app%20report%20result.jpg
The report using DotMatrix layout. I have drop TfrxDotMatrixExport. And also have tried to change font and layout for the print but still cannot achieve the same result.
Thank you for your help.
I have found the solution, Mr. Ken White answer is right, i have to used Escape command to the printer.
My Printer is Epson LQ-2180, so i used Epson Escape Command to set the font to be appear larger.
Here's my solution:
ESC ! n --> where n = 8 (Emphasized)
In Decimal would be #26#33#8
Thank you for the help.
I use SPSS-22 on a Linux machine.
I would like to know, if I can somehow tell the editor to automatically introduce line breaks, once the edge of the window is reached, as I would like to insert some longer comments in the syntax without having to press return all the time.
The syntax editor will turn overly long lines red, but it will not wrap the lines for you. 251 characters is the maximum legal length, but you would probably not want lines that long in your output for readability, so wrapping them yourself is probably warranted.
You might be interested in the TEXT extension command for writing long comments that will appear in separate text blocks in the output rather than being buried in log blocks. TEXT supports html and rtf markup as well.
TEXT requires the (free) Python Essentials for Statistics. Details are on the SPSS Community website (www.ibm.com/developerworks/spssdevcentral), but the Essentials are automatically installed (unless you decline) with Statistics 22. I think TEXT is included in the Essentials, but if not, you can get it via the Download and Install Extension Bundles feature under Utilities.
I have been asked to update a program written in 1987 in Delphi (I guess). I have no documentation about this program only a few side notes the programmer took that don't make too much sense to make.
The cd show this files:
Size | Filename
19956 VP.DTA
142300 VP.LEX
404 VP.NDX
126502 VP.RCS
131016 VP.SCR
150067 VP.XEL
101791 vp.exe
Is anyone of this files a database? If so can I access it's data?
I tried several code decompilers but they show a message saying it was not a Win32 compatible application.
The program run in MS-DOS.
Is it possible to obtain the source code? Can I use this code in any way to build a new application?
Update01: I can run the program in MS-DOS. The program conjugate verbs and shows an example sentence where the verb can be used. The GUI is a little bit confusing and there is no help menu so I can't see all the capabilities of the program.
Update02: In conversation with the owner of the program we found another solution. He ask me if it was possible to have the program in a server and the clients could login in with a user and a password and execute the program in a terminal. I have an account in my university server, which I can access throughout ssh and compile and execute c programs in it. The server is in linux so I couldn't try the program in it. If I set up a windows server, can I have multiple people accessing and executing the program in a terminal? The program is an exe. Doesn't this raise some security issues?
Delphi is from mid nineties, so that probably means Delphi's ancestor Turbo Pascal, not Delphi.
Some extensions sound familiar, as shortened versions of words:
ndx = index
dta = data
scr = screen (?)
lex = lexicon (list of words or deduped strings in general) (?)
Screen was sometimes used for e.g. helpscreens, a medieval form of helpfiles, they are typicall ansi screens that can be loaded directly into screen memory
There is a fair chance that this is something handcrafted, specially if that date of 1987 and the general assumption "pascal" is true, and not generated by some known database package at all.
Reverseengineering the fileformat might be a more worthwhile way than trying to reverseengineering the app.
A good start would to be to take a the unix "file" command to see if it can recognize the file types. (the file command searches for signatures inside files, and there are windows ports. I use Cygwin's)
A devel experienced in such matters can also see a lot from a hexdump (specially the first parts of a file)
Is it possible to obtain the source code?
Probably not, you may want to look at something like IDA Pro which can disassemble applications to C using something like Hex-Rays.
Do you know what the application is supposed to be?
If it's ms-dos, you're probably better off just drawing up new requirements and doing new development.
Look for DeDe to reverse engineering a delphi compiled program. But as far as i know, delphi is a real compiler. So there is no way to de-compiled it. If you are able to read assembler code then you can try de-compile it. Clipper and Foxpro (dos version) are another stories cause they not real compiler.
This is definitely not Delphi. It might be one of the database centric languages like Clipper 1. .SCR probably means "screen" and defines I/O masks. .NDX is a table index and .DTA means "data".
If it is clipper, you might actually be lucky, because as far as I remember these programs were P code, so it could be possible to decompile it.
It looks like CLipper (NDX and SCR). If you have a DBF file then it's Clipper for sure. But some people renamed the DBF to something like DAT. If it is Clipper, I believe there was a decompile named Valkyrie.
What is the best way to print - syntax colored and well formatted - code from Pharo/Squeak on paper?
1) Is there a way to print directly from within Pharo/Squeak? (i use it on macosx)
2) Is there a way to export syntax colored, well formatted code from Pharo/Squak?
3) Are there external tools to color and format a filed out piece of code?
For the appendix in my master thesis I used the Pier CMS-to-LaTeX converter in the Pier-Documentation package. However, this plugin only takes class comments and method comments into consideration, it does not print the source code. Pier also provides a package ShoutPier for syntax highlighting of Smalltalk code, so I guess it would require little work to bring the two together. You can find the mentioned extension packages in http://source.lukas-renggli.ch/pieraddons.html.
Pharo browsers seem to use syntax highlighting.
What difficulty are you having reading Smalltalk code using the browsers and senders/implementors ?
Edit: Would something that produces UML give the overview you're looking for? The Dandelion website only shows downloads for old Squeak versions - I don't know if they would work with Pharo.
And perhaps this GSoC project "Generate UML diagrams from Smalltalk code for Pharo" suggests not.
Here's how I did it on my Mac, I think this should work on other platforms too.
Save your categories to a Monticello local folder on your disk -- see the Pharo manual on how to do this: http://book.pharo-project.org/book/PharoTools/Monticello/?_s=hdGOLc_FXsvVY1iR&_k=YYH-Ln8f5mtWZ8z2&_n&148
Browse to this folder, and unzip the .mcz file
You'll see all your code in snapshot/source.st file
You'll need to edit this a bit, to remove the ! characters for e.g., there might be a tool to do this?

There is webdoc project, which allows you navigating code in web browser:
http://ss3.gemstone.com/ss/webdoc.html
(and of course you can print code from your favorite web browser)..
1) Install shout from www.squeaksource.com
2) I don't know. May be you can customize shout.
3) In gnu-smalltalk you have a smalltalk mode for emacs. But I am not pretty sure to understand what you are looking for.
I wish to debug executables for which I have no code, using the Delphi Debugger.
WinDBG and other debuggers are no option in this case, as the given executables all call into my DLL, for which I do have code, obviously. My ultimate goal is, to see a stack-trace right down into the functions of the running executable.
I do have symbol-information for these executables, so I was hoping I could write my own .RSM files for this purpose. Will this work? Will the Delphi debugger pick up any .RSM file that it can find? And would that mean that other debug-information should be left out?
Do note that there are lots of executables that I need to debug, and for all of them I detect the symbols inside them myself, using a moderately advanced function-detection algorithm. So my main problem mainly is how to write .RSM files. For this I have to know the structure of the .RSM file-format. Is there documentation or example code available somewhere that shows me how to create such a file?
Any help is appreciated!
PS: Might you be wondering why I'm doing all this : It's all related to Dxbx - an open-source Xbox1 emulator. See sourceforce for details. New members are welcome!
I found a page that says the format is similar to CodeView (www.openwatcom.org/index.php/Debugging_Format_Interoperability)
There is a link to this reference at Microsoft's CodeView format specs
I doubt this fully answers your question, but maybe it will get you a little further?
