Question from a co-worker braving Managed C++ (I only do C#):

I’m having trouble including an ArrayList in a MFC application. My
intention is to call some C# DLLs from a VC++ extended stored procedure.
So, I thought I’d test in a simple dialog box application where its
easier to debug.

I created a Visual C++ Project -> MFC Application -> dialog interface

I added the following line in the OnBnClickedOk() method

ArrayList* myAL = new ArrayList();

I added the following three lines after the #pragma in the TestDlg.h
file

#using <mscorlib.dll>
using namespace System;
using namespace System::Collections;

Compilation yielded the following error

fatal error C1190: managed targeted code requires '#using
<mscorlib.dll>' and '/clr' option

I added the /clr option to the Property Page -> Configuration Properties
-> C/C++ -> Command Line -> Additional Options section

Command line error D2016 : '/RTC1' and '/clr' command-line options are
incompatible

I changed Both to Default in the Property Page -> Configuration
Properties -> C/C++ -> Code Generation -> Basic Runtime Checks section

Command line error D2016 : '/Gm' and '/clr' command-line options are
incompatible

I changed Yes to No in the Property Page -> Configuration Properties ->
C/C++ -> Code Generation -> Enable Minimal Rebuild section

Command line error D2016 : '/ZI' and '/clr' command-line options are
incompatible

I changed Program Database for Edit & Continue to Program Database in
the Property Page -> Configuration Properties -> C/C++ -> General ->
Debug Information Format section

error C3828: 'System::Collections::ArrayList': placement arguments not
allowed while creating instances of managed classes

The error occurs in the ArrayList variable definition, in particular the
new ArrayList() portion.


Thanks!

Place the line

#undef new

after the includes.

In debug mode you are pulling in a #define of new to DEBUG_NEW which uses
oplacement syntax to add information on the source line that made the
allocation.

Hi, isn't it better to create an .NET Windows Form, wherein you can use ArrayList Class ?

You can mail me if you wish, I can program somewhat C++ .NET 2003, maybe I can help via MSN: (e-mail address removed)

I wish you good luck, and I wish you succeed - No! I know you will succeed.


Have a good day further,
ryan

Hi Michae
i'm working with console applicatio
i have the same problem and i solve it in the following way
1) Go To ---Project Property->Configuration Property --->c/c++ --->/cl
2) Go To ---Project Property->Configuration Property --->Code Generation-->Basic Runtime Checks-->Default
3) Go To ---Project Property->Configuration Property --->Code Generation-->Enable Minimal Rebuild--> N
4) Go To ---Project Property->Configuration Property --->c/c++ -->General-->Debug Information Format-->Program Database (/Zi
5) Go To ---Project Property->Configuration Property --->Code Generation-->Runtime Library--><inherit from project defaults

those settings solve the proble

have a nice day
