Syncfusion www.syncfusion.com[^] has a great grid called "Essential Grid". It is developed by Stefan Hoenig, the man who build before the Stingray grid. It offers a "virtual mode" that can handle millions of rows. I like it! Regards, Holger Persch

Remember that int is 32bit in .NET. This should be enough number of objects to store in memory. Regards, Holger

Both macros are adding the ability to query runtime information with CObject::IsKindOf for the classes. But only classes declared with DECLARE_DYNCREATE are enabled to be created by CRuntimeClass::CreateObject. Normally all views used inside the "MFC-Document-View-Architecture" were created by the framework by a call to CRuntimeClass::CreateObject. Hope this helps. Best regards Holger Persch

No, i have just not recognized that there exists a copy method :-O. Best regards Holger Persch

The "=" operator can look like this:

class CMyClass
{
.
.
.

const CMyClass &operator =(const CMyClass &src)
{
	m\_String = src.m\_String;

	m\_StringArray.RemoveAll();
	m\_StringArray.Append(src.m\_StringArray);
	m\_StringArray.FreeExtra();

	return \*this;
}

public:
CString m_String;
CStringArray m_StringArray;
};

Best regards Holger Persch

This is because of CStringArray has no "=" operator. Best regards Holger Persch

Hi, I am a registered BCG-Soft customer of Business Components Gallery Library (PE) for two years now and i agree with Danoo, that this is definitively not the correct way for BCG-Soft to treat their customers. I know that BCG-Soft is busy with their work on the professional edition of the Business Components Gallery Library, but this is the second (or third?) time the monthly update (the customers have paid for this!) is interrupted for weeks. On the other hand i am very satisfied with the product and the support. Best regards Holger Persch

Hi, please have a look to the following article: http://www.codeproject.com/listctrl/listcheckbox.asp[^] Best regards Holger Persch

Hi, does anybody knows how to use list controls in virtual mode with C#? :confused: In unmanaged C++ this is done by setting the LVS_OWNERDATA style and handling the according notifications. Thanks in advance Holger Persch

You can use IDispatch* ,LPDISPATCH or IDispatchPtr (smart pointer created from import) to pass IDispatch pointers to your C++ methods. Kindest regards Holger Persch

Hi Uwe, I think the correct way is to dereive a new class from "CUGCellType" and overwrite the "OnDraw" method. I've done this in one of my projects. If you need further information, don't hesitate to contact me. Best regards Holger

Hi, I'm using Dundas's Ultimate Grid since 4 years and i can say it works fine. But it seems that Dundas has stopped developing its MFC-based products. I'am a Ultimate Toolbox subscriber too, but there were no toolbox news in the last 6 months. Best regards, Holger Persch
