Hi,

I am having trouble getting a MFC C++ app off the ground As a Child Process

if have inserted a __debugbreak in The CWinApp::CWinApp but apparently the code dies

before it reaches this point

When I try to debug this app stand alone with the VS studio debugger it gets

past CWinApp::CWinApp and dies in the CwinApp::Initinstance

I have inserted DEBUG_ONLY_THIS_PROCESS, Flag in the CreateProcess processing the

WaitForDebugEvent messages hoping to catch the error at initialization but haven't

gotten too far

I am thinking maybe there is a way to run CreateProcess stating the VS studio

debugger with .exe as parm to see what errors occur at initilazation

Thanks

Without seeing some code and more detail it is anyone's guess what may be happening.

Use the best guess

Here is my Code Main Program

I pasted the Child Process but it didn't seem to take so I am going to post it again
in the next post

Thanks for your help

Hi,

I think I found somewhat of solution there a Microsoft article

http://msdn.microsoft.com/en-us/library/vstudio/jj919165.aspx[^]

Which has a section to automically tart a process in the debugger

I created a folder for my app in

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

And from the contents menu added the name of VS debugger

After I executed the Create Process I got a Dialog Box message from Just in time debugger

as it seemed to have garbage for the app to debug

outside of the folder name where dO I put the name of the executable to debug

Thanks

Does the application that you are spawning as a child process work on its own?

You can with windbg.exe. There is a rsgistry setting to lauch the app under windbg, it is used for debugging services, have a google for it.

Yes, ProgramFox already mentioned that. Not sure why OP is being downvoted here, since the question seems quite reasonable.

Hi, all

I've locate the error at line 13770 in exprtk.hpp, which is:

Quote:
static inline std::string id(expression_generator<type>& expr_gen,
const details::operator_type o0, const details::operator_type o1)
{
return (details::build_string() << "(t" << expr_gen.to_str(o0) << "t)" << expr_gen.to_str(o1) << "t");
}

I comment the command after "<<", and the problem remains. Thus I can narrow it to

Quote:
details::build_string()

I extrememly appreciate if anyone can bring some solution.

Many thanks in advane.

Long
