code for activating a breakpoint at runtime

5-Oct-06 2:16

u can use OpenThemeData() function to open a specific theme. Then pass this handle to various DrawTheme...() functions.

Hi all

I need to insert a DATA breakpoint on one of my variables; I need that this breakpoint should be active only after a particular condition occurrs in time in another point of the code.

I don't want to pause the debugging to manually active this breakpoint; the activation should be automatically triggered some way.

Do you know a way to activate this breakpoint dinamically while my code is running? There is code for activating a breakpoint at runtime?

Regards
Manu Stone

At runtime, all debugging info is discarded, is it even possible?

I've been suggested DebugBreak(). I still haven't the change to test it ( I will do immediately) so I don't know ( probably it will) disable in the Release version of the app.

Do you know some other functions or practical methods to insert breakpoint in the code? I'm really interested in DATA breakpoints?

Thanks for your response.

At run time or through writing assembler instructions? I don't know if it can be done at run time, sincerely. But with asm its possible.

__asm int 3;

Hi brahmma

thanks for your response!

I'm Sorry, but I never heard before code like this _asm int 3..is this coding directly the assembly or what? Can you suggest some good web/paper/reference to understand/learn it?

Its not _asm, it is __asm.

You can use the __asm keyword to invoke the inline assembler.

If you want to enable a break point conditionally, then you can use this assembler instruction the following way.

if(iBreak == 1)//Condition
{
   __asm int 3;//enable break point
}
else
{
...
}
</code>

Hope this helps. Please note that you must be in debug mode, to have debugging info available.

u can u make a break point to activate only when one condition is satisfied. put a ordinary break point in the line where u want to put the break point. Press ctrl + b( edit->break point ). U will find the option to make the break conditional.

OR else u can use the DebugBreak(); or __asm int 3;

Hi Naveen

Thanks for your response!
I think that DebugBreak() is what I need.

Do you know some other function like this to insert break point in the code?
I'm really interested in it, with particual attention (if existing) to DATA breakpoint ( the one triggered when a value change at a certain address ).

No, except the one that i already told __asm int 3;

sorry.I dont know any such functions and i dont think there is any.

Also you can consider conditional compilation using #ifdef/#endif/#define preprocessor macros, instead of finding tricks and hacks to use breakpoint at runtime.

manustone5-Oct-06 2:48

Hi Link2006

I think that what I need is ( suggested by others developer) to use DebugBreak() in my code. I think that also combining DebugBreak with conditional compile allow me to create some special condition when to call DebugBreak().

Did you mean this way or simply create #ifdef #endif with a breakpoint in the middle?

I am trying to compile some cpp files which have 2 byte chars (something like C:\日本\myfile.cpp) in its path but I am unable to compile it with VS 2005. Is there any way to compile it ?

You must be thinking why I need 2 byte chars in folder name ? Actually there is some crash in application at launch time if folder have 2 byte chars, I want to debug the same. Please help if some one know the way to debug it with VS 2005.

What is the exact error you are getting? I just tried the same and go the following

BSCMAKE: error BK1506 : cannot open file '.\Debug\????.sbr': No such file or directory

It sounds like the compiler is still using byte-oriented character sets in this area. It might work if you were trying to compile with a Japanese version of Windows.

You could try compiling in the normal location, then adding a post-build step to copy the final executable (and its .pdb file) to the location that is causing the problem. Then, in Project Properties, Configuration Properties, Debugging, set the 'Command' to be the path you need the program to run from. Or, simply set the Output Directory (in Configuration Properties, General) to be the path that has the problem, although the linker might struggle with this.

Stability. What an interesting concept. -- Chris Maunder
