I new to PIC mplab and PICs. I developed a program that I run under the simulator and things seem to be working as expected. Now, I'd like to record what my program is doing on port C.
I have a text script that applies stimulus. Once things get going, I detach from that script and add a trace register entry for LATC with trigger Demand and a Trace Filename. But nothing gets written to the file.
Any hints would be appreciated.
Well, I have no idea why the above did not work. I was able to use a PC=trigger to trace RAM locations. I decided trace register wasn't what I wanted anyway. In it's place, I defined a macro that captured whatever I wanted into RAM locations and did a CALL debug. By setting a BREAKPOINT at debug, I was then able to WATCH whatever SFRs and RAM locations I wished.

I am trying to use an application called CLUT.exe which is an old application for MS-DOS that can be used to reindex NTX files for DBF databases.
(This is not the main topic, but I am just writing this if someone wants to test the app and don't trust at all about the content).
The problem starts when trying to run the command line version through console (cmd.exe) and this error appears:
C:\>CLUT.exe [arg1] [arg2] [arg3]
run-time error R6009
- not enough space for environment
So, according to what I've searched, this could be a possible solution:
http://support.microsoft.com/default.aspx?scid=kb;en-us;230205
but it doesn't work and every alternative that I found to solve this over the internet is the same.
Another alternative could be to make right-click in the .exe file, go to Properties then Memory tab and increase the Initial environment memory from Auto to the max value but it doesn't work too.
Well, I am stuck and no "possible" solution is working for me. If someone is interested, knows more about this issue and want to test, you can download the application from here (click "Free Download" green button):
http://www.filebasket.com/free/Development-Clipper-programming-language/clut-exe/13996.html
or directly from my DropBox:

Just to know, I am using Windows 7 and the CLUT.exe application is a Clipper based app (old programming language) that may run under windows console (cmd.exe).
Wikipedia does mention other dos emulators but, oddly, doesn't mention BOCHS.
Reindexing NTX files is not a difficult thing to do, and can be done with tools other than CLUT. For example, many of the utilities listed on this part of Download32 could be used. Otherwise, you could write your own using Harbour Project or xHarbour. Or contact me off list and I'll cook up something in Clipper 5.3.
LATER
If I read the README correctly for CLUT, it's a replacement for the DBU utility that comes with Clipper 5.x. I can supply you with a build of that if you're unsuccessful with other approaches.
Is there a fast way to search/scan the memory of a process for a specific value,
find the location of this value, edit and save it?
There are examples like Peeping Tom, but it's very slow and has issues with Vista & Win7.
You will have to debug the process (i.e. the equivalent of attaching the process to your custom debugger) and use ReadProcessMemory to read and WriteProcessMemory to write.
This is what the Delphi Code Coverage project is doing to insert breakpoints to track code coverage at runtime.
Look at the class DebugProcess, it has methods to read and write to the memory of the debugged process.
I have a very simple Delphi 2010 dll that I load from a Visiual Studio 2008 C ATL console application (MVF GUI app does not work either). When I debug the console app from the IDE directly - no break points - the output from the application is not correct but when I run the app directly or if I attach to the process with the debugger then it works 100%. Debugging the same dll from a Delphi console app (i.e. running it from the IDE) also works.
The VS debugger seems to break the app depending on how you run it. VS2010 does the same!
I have made 100% sure - several times! - that the data types and calling convention of the dll exports and those in the console app match. I can go into more detail but I don't want to confuse the matter with what may be irrelevant information. Please tell me if I have to go into the specifics of the code if what I have offered is not enough.
Has anyone experienced this sort of thing and know how to fix it?
I've got similar problem once (different behavior in IDE/debugger and in standalone application). It turned out, that I've checked the value of unset variable. Debugger allocated it (always!) in previously used block of memory, such that the value was not empty and the application worked correctly (because only the conditional block was erroneous). However, OS sometimes put the application in empty memory block (filled with 0s), the condition failed and application crashed.
Maybe this is the issue? Try using OutputDebugString()'s to track down values of variables during the library runtime. Without some source code I believe, that it's not easy to say, what might be the reason.

I'm finishing an internship at a company and have just been thrown onto this project for the last month where the program is built upon an engine that they "failed" to buy the source code for. Now I've been given the task of finding out why it is failing, on only certain conditions and customer feedback hasn't been great. The main developer for the project is also out on leave for several months.
I have the engine install and know the language it was written in (delphi6?).
note which I have never had to use
I have our products msi.
I'm expected to go through the regular app and pinpoint the problem. I suspect it is something to do with fields not being re-initialized properly.
Is there a way to attach a debugger to the exe to see callstacks and all that hotness?
Any help that would avoid countless use cases would be received gratefully.
You can attach the Delphi debugger to any running process (like all other win32 debuggers out there) but I don't think the experience will be near what you expect. Delphi produces really tight executables which means the info for building human readable callstacks or any kind of "hotness" are simply not there.
Your only chance is in that if your application is a Debug release. In that case, Delphi debugger should help more than a generic debugger.
You might also want to have a look at this thread - Is there a program to decompile Delphi?
In Delphi 2006 (not sure about 6) you can attach the debugger to a running process.
You only get assembler instructions, registers, flags, memory dump and stack (hex). Hope that is enough.
Nice, I tried to attach to the ide/debugger and they disallowed that ;-).
How to generate the Symbols file of a PowerBuilder program for dump analysis?
Are you running into a problem with a compiled PowerBuilder application?
I've never used the Microsoft debugger, however, I have used Dependency Walker and ran my app from within that environment. Usually that helps us if we have missing deployables, etc.
If you need a stack dump, have you thought about running the app from the Run window and adding the /debug option after the name of the app? That creates a call stack log that shows all your commands being called, etc. Probably would get you what you need.
Please advise.
You can install Dr. Watson (drwtsn32) to automatically create a crash dump when/if your application dies.
That said, the dump will usually only be useful if you are calling into native DLL's. Otherwise the stack will just include various PBVM calls that will be difficult to correlate back to actual source code lines.
