Hi

I am using embedded visual C++ and new to it.

I have problem when I want to use try/catch. my try/catch code is as below:

try
{
m_oaItem.Add(pItem);
SetModifiedFlag();
m_iCurPosition = (m_oaItem.GetSize() - 1);
}
catch (CMemoryException* perr)
{
AfxMessageBox("Out of Memory", MB_ICONSTOP | MB_OK);
if (pItem)
{
delete pItem;
pItem = NULL;
}
perr->Delete();
}

When I build the application it give me error and warning as below:

C:\Documents and Settings\user1\My Documents\MobileInventory\MobileInventoryDoc.cpp(9 3) : warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify -GX
C:\Documents and Settings\user1\My Documents\MobileInventory\MobileInventoryDoc.cpp(1 00) : error C2665: 'AfxMessageBox' : none of the 2 overloads can convert parameter 1 from type 'char [14]'

I have tried solution below:

Project --> Settings... --> C/C++
Under "Category" Select C++ Language and check the "Enable exception handling". You can now do a rebuild all. You will prompted to save this project setting when you exit the IDE.

But I cannot find "Enable exception handling" option in the dialog in embedded Visual C++.

Can someone pls help, thanks in advance.

Best Regards

after 1 days struggled finally get the solution as below:

---------------------------------------------------------------------------

Windows CE 3.0 and earlier (versions targetted by eVC 3.0) do not support
C++ SEH, so you cannot use try/catch (and thus specifying -GX wouldn't help
you). You can use C exception handling (try/except), however.

For Windows CE 4.0 and later (use eVC 4.0 for those targets), it depends on
the actual Windows CE configuration if C++ SEH is supported. If it is, you
can use try/catch, but you do have to manually add -GX to the compiler
command line. You do so by clicking the Project\Settings... menu item in
eVC, select the C/C++ tab, and then go into the edit box at the bottom of
that dialog where the command line is and adding "-GX".

After adding "-GX" in command line, and then Rebuild All.
