Question:

put_EventCallbackObject compile error

Apr 29 '14 at 17:04

Hi

Using VC2013 and the latest libraries. I have this code:

CMyFtpTransferZipProgress ftpProgress(&m_wndStatusBar, strTarget); ftp.put_EventCallbackObject(&ftpProgress);

I updated CMyFtpTransferZipProgress to inherit from CkFtp2Progress and did a full rebuild but I still get an error:

4>MainFrm.cpp(2773): error C2664: 'void CkFtp2W::put_EventCallbackObject(CkFtp2ProgressW )' : cannot convert argument 1 from 'CMyFtpTransferZipProgress ' to 'CkFtp2ProgressW *'

I have followed:

Thanks.

Answer

If using the wide-char version of the Chilkat class (i.e. the one ending with a "W", such as CkFtp2W), then use the wide-char version of the event callback class.

You'll find it in the CkFtp2ProgressW.h header file.

Also:

/*

To receive progress events (callbacks), create a C++ class that 
  inherits this one and provides one or more overriding implementations 
  for the events you wish to receive.
*/
// When creating an application class that inherits the CkFtp2ProgressW base class, use the CK_FTP2PROGRESSW_API 
// definition to declare the overrides in the class header.  This has the effect that if for
// some unforeseen and unlikely reason the Chilkat event callback API changes, or if new
// callback methods are added in a future version, then you'll discover them at compile time
// after updating to the new Chilkat version.

// For example:
/*
    class MyProgress : public CkFtp2ProgressW
    {
    public:
        CK_FTP2PROGRESSW_API
...
};
