OO4O & C++ : COM or class library?

Hi,
What do you choose when using OO4O in C++? Do you use raw COM calls, or do you use the OO4O C++ library?
I haven't seen much talks about the OO4O C++ library here, or anywhere else on the net.
Thanks

The C++ class library is certainly the easiest route to take. You should find the OO4O help file sufficent for reference purposes.
I have not come across anything that you can do using the COM interface directly that you can not do using the C++ library (except blob handling way back in version 3.3.0.0.0)

Creating a class library in VS2013 that can be referenced by a VB6 application and newer applications

I need to create a class library in VS2013 that can be referenced by a VB6 application and newer applications. I heard something about
COM Interop but have no idea where to start. I am assuming I would develop a class library in VS2013 and then package the assembly for COM. Any good sample projects on this out there?

How to insert null in C++ Class library

I am using oo4o Class library. I am inserting arrays into the database
This is my code (it is simplified):
// C++ Code
OStartup();
oRes = m_o_Session.Open(); // m_o_Session is OSession // oRes is oresult
oRes = m_o_db.Open(m_o_Session,sSource,sUser,sPassword); // m_o_db is ODatabase
oRes = m_o_db.BeginTrans();
// the insert proccess
// Add Params
OParameterCollection oParamCol = oDB.GetParameters();
OParamArray o_NUM_INDEX_Ary = oParamCol.AddTable("xi_lv_NUM_INDEX",OPARAMETER_INVAR,OTYPE_NUMBER,10);
OParamArray o_TEXT_Ary = oParamCol.AddTable("xi_sv_TEXT",OPARAMETER_INVAR,OTYPE_VARCHAR2,10,250);
OParamArray o_NUMBER_OPT_Ary = oParamCol.AddTable("xi_dv_NUMBER_OPT",OPARAMETER_INVAR,OTYPE_NUMBER,10);
for(int i =0;i<10;i++){
o_NUM_INDEX_Ary.SetValue(i,i);
o_TEXT_Ary.SetValue("asdasd",i);
o_NUMBER_OPT_Ary.SetValue(??????,i);
oRes = oDB.ExecuteSQL("INSERT INTO GEN_TABLE_TEST_T (NUM_INDEX,TEXT,NUMBER_OPT) VALUES (:xi_lv_NUM_INDEX,:xi_sv_TEXT,:xi_dv_NUMBER_OPT)");
oParamCol.Remove("xi_lv_NUM_INDEX");
oParamCol.Remove("xi_sv_TEXT");
oParamCol.Remove("xi_dv_NUMBER_OPT");
oRes = m_o_db.CommitTrans();
oRes = m_o_db.Close();
m_o_Session.Close();
OShutdown();
my question is where I marked ?????? I want to insert null to a numeric field
I tried to put NULL instead of ?????? - does not work
I tried to put OValue initialized with null instead of ?????? - does not work
and I need to send him in the insert Sql because sometimes it does not null and i have to give him value.
thanks is advance
Yoav

Just create an empty OValue object:
OValue nullv; // construct null value
then call the appropriate SetValue method...
xxx.SetValue(nullv);
Should do it.

Java Class Library

What's the online Java Class Library reference site?
I swore it was on this Java.sun.com site, but I can't seem to locate it again.

Creating a class member VI from a template locks the class library.

I have a LabVIEW (8.6.1) class where I need to create a number of very similar member VI's. In order to make this process more convenient, I created a couple of VI templates. However, I've found that creating a new VI from the template always locks the class library. The library then remains locked until I close and reopen the project.
When I select "Why is library locked?" from the context menu, I'm told:
"The library is locked because: This LabVIEW class is loaded in multiple application instances. Classes must be in only a single application instance to be edited. The containing library is locked."
I have the same problem if I create a new project (see attached ZIP file), add a class, and then add two templates. Everything seems OK if I have only one template.
Am I doing something wrong, is this a bug in LabVIEW, or do I misunderstand the expected/intended behavior of template VI's? Is there a way to "unlock" the class library without closing and reopening the project?
Thanks in advance,
Mark Moss

Could i use page unload event in Class Library (Web part)?

Hi,
I am creating Web Part using visual studio class library. I am going to deploy it in SharePoint environment.
I want to do some functionality while page unload. Is there anything like that?
Could anyone tell about it?
Thanks & Regards
Poomani Sankaran

Hi,
According to your description, my understanding is that you want to create a web part programmatically and then do some functionality in the page unload event.
There is a web part method called WebPart.OnUnload method, you can override this method and add the custom code to the override method.
Here are some detailed articles for your reference:

Oracle Spatial Java Class Library Download?

Hello,
where can I download the Oracle Spatial Java Class Library? I installed OracleXE which can handle SDO_GEOMETRY types and now need the java library for programming against the database.
greetings
Peter

If you mean by samples that show you how to manipulate Geometry types than you can find this tutorial using java and connecting to your DB via Oracle Spatial Network Data Model (NDM) https://spatial.samplecode.oracle.com/servlets/ProjectProcess?pageID=0Zl7oV
My personal experience, it would be good idea to have oracle 11g Release 2 installed.
It shows you different ways to query spatial data. You might also be interested in this documentation on oracle Topology and NDM Developers guide: http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28399.pdf

How to avoid having to clean a portable class library every time?

WinRT Project Foo references a portable class library PCLFoo. Whenever a change is made to Foo and it is run (by pressing F5 or Ctr+F5), the following error occurs:
The type or namespace name 'PCLFoo' could not be found (are you missing a using directive or an assembly reference?)
Everything will be fine after cleaning PCLFoo (right-click >Clean). Is there a way to avoid having to do this cleaning every time?

WRL Class Library Project Template

I'm trying to check out WRL by following
this walkthrough using Visual Studio 2013. A part of the instructions has a link to this instructions
which is to create a project using the WRL class library project template. The problem is I cannot find the said project template. I saw this post
in SO that gives a link to the visual studio gallery but I'm getting a "This item is not yet published" error on the link. Thank you.

Yeah, I was basically trying to use WRL to develop a way to expose a native C++ DLL via COM so that I can use it in a C# WPF application. We're not really concerned on developing a Store App.
We've decided to try out C++/CX instead and try to use it as a wrapper for the native C++ DLL. I also, created a Window 8.1 virtual machine, so now I was able to create a Windows Runtime Component project.
Although, if anyone ever come across the same problem, using a web page history website, I was able to find this link (http://visualstudiogallery.msdn.microsoft.com/346e6fbc-6508-43c8-af7f-9a922bb57128/file/72996/2/WRLVSIXProject.vsix)
to the VSIX installer.

JRockit H27.2.1 for Harmony Class Library released now

JROCKIT H27.2.1 FOR HARMONY CLASS LIBRARY RELEASED NOW
BEA has released a 32-bit partial implementation of the Java Standard Edition Version 5 Specification for Windows on the Intel architecture that will work with the Apache Harmony Class Library for evaluation purposes.
DOWNLOAD(S) AND VERSION(S)
The JRockit H27.2.1 version has been tested with the Apache Harmony Class Library hdk-r487452 version.
* JRockit H27.2.1 (http://dev2dev.bea.com/jrockit/jrockitVM)
* Apache Harmony Class Library hdk-r487452 (http://people.apache.org/builds/harmony/snapshots)
DISCLAIMER
JRockit H27.2.1 is an experimental release for evaluation purposes only.
BEA will not support this VM. BEA does not guarantee updates or service packs to this VM. The supplied class library implementation is incomplete and not Java compatible. Use H27.2.1 on your own risk.
This BEA JRockit VM is not a part of the Apache Harmony project.
BEA will follow up issues and questions regarding this release at this forum as time allows, but cannot guarantee responsiveness.
HOW TO INSTALL
* Download the Apache Harmony Class Library hdk from http://harmony.apache.org
Unpack this to a location of your choice.
* Locate the directory <path-to-jre>/bin. Preferably rename or remove the subdirectory 'default' (this is not required but recommended)
* Download JRockit H27.2.1 from http://dev2dev.bea.com/jrockit/jrockitVM
Unpack JRockit H27.2.1 to <path-to-jre>. You should now have a new subdirectory named 'default' in the 'bin' directory.
* Verify by running '<path-to-jre>/bin/java -version'. If the program reports running JRockit this means the product is now installed.
KNOWN ISSUES
* There is no bytecode verifier supplied with JRockit for Harmony.
* The core class library provided by JRockit for Harmony is not java compliant, nor is it a complete implementation of J2SE 5.
* There is no support for java.lang.management.
* There is no support for extended JRockit tools (such as management console).
* There is no support for debugging via JDI. JRockit for Harmony contains an implementation of JVMTI (Java Tools and Management Interface), but no bridge for JDI.?

See the documentation on how to disable optimizations for just a single method: http://e-docs.bea.com/jrockit/geninfo/diagnos/crash.html#wp1002526
If you need a fix, please open a support case with BEA.
Thanks,

Portable class library - SSL certificate ignore support.

Hi,
We are developing mobile based project targeting to windows and ios platform.
1. Project has portable class library that is been shared among all this platforms.
2. We have asp.net web api services for data provider hosted on server with http and https (ssL) enabled.
3. We are successfully able to call web api methods using System.Net.HttpClient in portable class library and data is provided by the utility helper methods to all platforms.
4. Now based on the specific requirement we have to utilized https enabled service and we have to switch to ssl enabled call.
5. Based on my research over internet "ServicePointManager.ServerCertificateValidationCallback" is one we can use in .net native framework libraries but not available for portable libraries.
If anyone can help in this area that how can we make https call from portable class library.
Thanks in Advance,
Brajesh patel

Hello Brajesh,
As far as I know, in these currently released PCL, there seems to be no way to use the SSL certificate for http request.
My suggestion is that you could invite your friends or colleagues to vote this idea in below link(someone else already psot this request to the team):
http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/4784983-support-server-ssl-certificate-chain-inspection-in
With the increase of the the voice number, this priority of this idea would be improved.

How can i change the class in the Class Library project to be static or public so i can use it from the windows application project ?

First i know that when i make any changes to the class library project i need to rebuild the project then to remove the Capture.dll from the TestScreenshot project and then to add again the updated Capture.dll
The problem for example in this case i'm trying to use a public static variable i add in the DXHookD3D9.
In the DXHookD3D9 i added this public static variable:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
//using SlimDX.Direct3D9;
using EasyHook;
using System.Runtime.InteropServices;
using System.IO;
using System.Threading;
using System.Drawing;
using Capture.Interface;
using SharpDX.Direct3D9;
namespace Capture.Hook
internal class DXHookD3D9: BaseDXHook
public DXHookD3D9(CaptureInterface ssInterface)
: base(ssInterface)
LocalHook Direct3DDevice_EndSceneHook = null;
LocalHook Direct3DDevice_ResetHook = null;
LocalHook Direct3DDevice_PresentHook = null;
LocalHook Direct3DDeviceEx_PresentExHook = null;
object _lockRenderTarget = new object();
Surface _renderTarget;
public static decimal framesperhourtodisplay = 0;
protected override string HookName
get
return "DXHookD3D9";
List<IntPtr> id3dDeviceFunctionAddresses = new List<IntPtr>(
framesperhourtodisplay
The problem is i can't even get to the Capture.Hook namespace and not to the DXHookD3D9 from the TestScreenshot application window project.
This is a screenshot:
For example fro the FramesPerSecond class i can use it get to it from the windows forms application.
namespace Capture.Hook
/// <summary>
/// Used to determine the FPS
/// </summary>
public class FramesPerSecond
int _frames = 0;
int _lastTickCount = 0;
float _lastFrameRate = 0;
Since it's public i guess.
But if i will change the DXHookD3D9 class from internal to public:
public class DXHookD3D9: BaseDXHook
I will get error on the DXHookD3D9:
Error 1
Inconsistent accessibility: base class 'Capture.Hook.BaseDXHook' is less accessible than class 'Capture.Hook.DXHookD3D9'
And the BaseDXHook class:
namespace Capture.Hook
internal abstract class BaseDXHook: IDXHook
protected readonly ClientCaptureInterfaceEventProxy InterfaceEventProxy = new ClientCaptureInterfaceEventProxy();
public BaseDXHook(CaptureInterface ssInterface)
this.Interface = ssInterface;
this.Timer = new Stopwatch();
this.Timer.Start();
this.FPS = new FramesPerSecond();
Interface.ScreenshotRequested += InterfaceEventProxy.ScreenshotRequestedProxyHandler;
Interface.DisplayText += InterfaceEventProxy.DisplayTextProxyHandler;
InterfaceEventProxy.ScreenshotRequested += new ScreenshotRequestedEvent(InterfaceEventProxy_ScreenshotRequested);
InterfaceEventProxy.DisplayText += new DisplayTextEvent(InterfaceEventProxy_DisplayText);
~BaseDXHook()
Dispose(false);
How can i solve it so i can use the variable framesperhourtodisplay in the DXHookD3D9 class with the TestScreenshot windows forms application ?

Hi,
I dont know if it will work here, since I dont know the complete structure, but the base call must be public, if the derived class is public, so the base class is at least as accessible as the derived class.
Try make the base class public. (And maybe the base-class IDXHook of the base also...)
Or use a different approach and make only the properties public that are needed to be public by adding an extra class...
A structure could look like:(you need to create a class thats public in your dll and expose a property, and set this property in the internal class...)
In the Accessing class (here Form1)
public partial class Form1 : Form
public Form1()
InitializeComponent();
private void Form1_Load(object sender, EventArgs e)
C c = new C();
MessageBox.Show(B.F.ToString());
and in the class Lib:
internal class A
public A()
B.F = DateTime.Now.Millisecond;
public class B
public static int F { get; set; }
public class C
public C()
A a = new A();
(add a referenc to the class lib from the accessing project)
Regards,
Thorsten
