mfc >> Urgent help with CStringArray

by Gaetano Sferra » Tue, 25 Nov 2003 18:54:51 GMT

Hello,
i need to return a CStringArray from a class method, but CStringArray (and
CStringList also) doesn't have a copy constructor!
I want avoid memory allocation within the metod because I don't want to
force the class user to deallocate pointers... this is the piece of code:

const CStringArray MyClass::MyMethod()
{
CStringArray StrArray;

for (...)
StrArray.Add("something");

return StrArray; // this will generate a missing copy constructor
compile error
}

Thank you,
Gaetano Sferra

Either you derive a class CMyStringArray from CStringArray (and just add
a copy contructor) - which is bad because a lot of stuff will be copied
whitout necessity

or you rewrite your function to something like

void MyClass::MyMethod(CStringArray& StrArray)
{
for (...)
StrArray.Add("something");
}

3. Urgent urgent help.. 

Hi all...

I have an application due out this monday. I've been working on it for
the past week or so and foolishly haven't run it in Release mode. I've
had release / debug problems in the past (different applications)..
but nothing like this.

The application is a dynamically linked MFC dialog application.
Nothing special really. Runs fine in debug.

However, when I run in Release, nothing happens! Nothing! According to
the task manager, the application is running - it just never shows.

I put a message box into the constructor:
CTestApp::CTestApp()
{
	AfxMessageBox(_T("Test"));
}

It does not reach this point when running in Release. No message box.

Where do i even start to look for the problem?


Thanks a lot

 How to perform this. I couldnt get the msi running in the process it
