How To Use COPY in WebDAV to Copy a Mail Item to Another Folder (290407)

MORE INFORMATION

The following Visual C++ code sample uses the HTTPRequest object to send a COPY request to the Exchange server. This sample requires Msxml.dll version 2.0 or later.

To run this sample, follow these steps:

1. Under Public folders, create two new folders and name them "Testfolder1" and "Testfolder2".
2. In Testfolder1, create a mail item with the subject "test".
3. In Visual C++, create a new Win32 console application and name it "Mysample".
4. Replace the code in the Mysample.cpp file with the following code:

   #include<stdio.h>
   
   //TODO: Change the path here if your Msxml.dll file is in a different location.
   
   #import "c:\winnt\system32\msxml.dll"
   using namespace MSXML;
   
   //To  use MSXML 4.0 import the dll msxml4.dll instead of msxml.dll as follows 
   // #import "c:\winnt\system32\msxml4.dll"
   // using namespace MSXML2;
   
   int main(int argc, char* argv[])
   {
      CoInitialize(NULL);
      try
      {
            //TODO: Change the line below to reflect your server.
      bstr_t yourServerName = "YourServerName";
   
      bstr_t sSourceUrl = "http://" + yourServerName +
         "/public/Testfolder1/test.eml";
      bstr_t sDestUrl = "http://" + yourServerName +
         "/public/Testfolder2/test.eml";
      bstr_t sMethod = "COPY";
            
      //TODO: Change the 2 lines below to reflect your user name and password.
      _variant_t vUser = L"YourDomainName\\User1";
      _variant_t vPassword = L"password";
     
   
      // To use MSXML 4.0 use the following declaration and creation of   pXMLHttpReq
      // IXMLHTTPRequestPtr pXMLHttpReq= NULL;
      // HRESULT hr=pXMLHttpReq.CreateInstance("Msxml2.XMLHTTP.4.0");
   
          
      MSXML::IXMLHttpRequest* pXMLHttpReq=NULL;     
      HRESULT hr = ::CoCreateInstance(__uuidof(XMLHTTPRequest), 
         NULL, 
         CLSCTX_INPROC_SERVER, 
         __uuidof(IXMLHttpRequest), 
         LPVOID*)&pXMLHttpReq);
       
   
      if (S_OK != hr)
      {
         printf("XML Http Request pointer creation failed\n");
         return 0;
      }
   
      // Call open function.
      _variant_t vAsync = (bool)FALSE;
      pXMLHttpReq->open(sMethod, 
         sSourceUrl, 
         vAsync, 
         vUser, 
         vPassword);
      pXMLHttpReq->setRequestHeader((bstr_t)"Destination", sDestUrl);
    
      // Send the request to set the search criteria.
      pXMLHttpReq->send();
   
      // OK, get response.   
      long lStatus;
      pXMLHttpReq->get_status(&lStatus);
   
      printf("\n~~~~~~~~\n%d\n", lStatus);
      BSTR bstrResp;
      pXMLHttpReq->get_statusText(&bstrResp);
      printf("\n~~~~~~~~\n%s\n", (char*)(bstr_t)bstrResp);
   
      _bstr_t bstrAllHeaders;
      bstrAllHeaders = pXMLHttpReq->getAllResponseHeaders();
      printf("\n~~~~~~~~\n%s\n", (char*)bstrAllHeaders);
   
      BSTR bstrResponseText;
      pXMLHttpReq->get_responseText(&bstrResponseText);
      printf("\n~~~~~~~~\n%s\n", (char*)(bstr_t)bstrResponseText);   
      }
      catch(_com_error &e)
      {
      printf("Error\a\a\n\tCode = %08lx\n"
         "\tCode meaning = %s\tSource = %s\n\tDescription = %s\n",
         e.Error(), 
         e.ErrorMessage(), 
         (char*)e.Source(), 
         (char*)e.Description());
      }
   
      CoUninitialize(); 
      
      return 0;
   } 
   					

5. Make the changes marked by "TODO:" in the code.
6. Compile and then run the code.
   
   Note that the test.eml mail item is now in both Testfolder1 and Testfolder2.
