Vs2010 try catch is invalid?-CodePudding

Vs2010, using MFC to do a thing, found the try and catch to catch exceptions, the original vs2008 can be set by the project properties - & gt; C + + - & gt; Code generation - & gt; Enable c + + exception is set to: yes, but there are SEH exception (/EHa), and can catch exceptions, but not 2010, friend ever encountered the same problem can give a solution, thank you very much,

Void CaDlg: : OnBnClickedOk ()
{
Try
{
Int * a=NULL;
* a=1;
}
The catch (CMemoryException * e)
{
AfxThrowMemoryException ();
AfxMessageBox (" DDDDDDDDDDDDD ", MB_OK);
}
The catch (CFileException * e)
{
AfxThrowFileException (CFileException: : fileNotFound);
AfxMessageBox (" DDDDDDDDDDDDD ", MB_OK);
}
The catch (CException * e)
{
Throw;
AfxMessageBox (" DDDDDDDDDDDDD ", MB_OK);
}
}

with SEH __try __except capture

That's my hair, __try and __except can be caught, but want to use the catch, it's very entanglements, original vs2008 platform is no problem,

CodePudding user response:

You add a catch (... Try)?

CodePudding user response:

Or you changed the/EHa to/EHsc try?

Sometimes not to "call a function name + each parameter value, after entering the function of each parameter values, intermediate variable values, exit the function return value of preparation, return to the function to call after the function value of the parameter name + + return value" this information to write logs to a file is where no matter how to also can not find the problem, including the capture all kinds of abnormal , write the log to the screen and single step or set a breakpoint or generated the core or the DMP file,... These methods are not! Write logs to a file reference below:
