如何使用 C++ 中的 MAPI 以编程方式向已知收件人发送带附件的电子邮件? MAPIS发送邮件()
这个问题类似,但没有显示如何添加收件人。
我该如何做到这两点?
我们希望为尽可能多的 Windows 平台(从 XP 及更高版本)提供最广泛的支持
我们正在使用 Visual Studio 2008
本质上我们希望发送一封电子邮件,内容包括:
- 预先填写的目标地址
- 文件附件
- 主题行
来自我们的程序以及使用户能够添加任何信息或取消它。
编辑 我正在尝试使用 MAPISendMail() 我从顶部附近链接的问题中复制了大部分代码,但我没有收到电子邮件 dlg 框,并且从调用中得到的错误返回是:0x000f -“系统找不到指定的驱动器”
如果我注释掉以下行设置收件人,它工作正常(当然,然后我没有预先填写收件人)
这是代码:
#include <tchar.h>
#include <windows.h>
#include <mapi.h>
#include <mapix.h>
int _tmain( int argc, wchar_t *argv[] )
{
HMODULE hMapiModule = LoadLibrary( _T( "mapi32.dll" ) );
if ( hMapiModule != NULL )
{
LPMAPIINITIALIZE lpfnMAPIInitialize = NULL;
LPMAPIUNINITIALIZE lpfnMAPIUninitialize = NULL;
LPMAPILOGONEX lpfnMAPILogonEx = NULL;
LPMAPISENDDOCUMENTS lpfnMAPISendDocuments = NULL;
LPMAPISESSION lplhSession = NULL;
LPMAPISENDMAIL lpfnMAPISendMail = NULL;
lpfnMAPIInitialize = (LPMAPIINITIALIZE)GetProcAddress( hMapiModule, "MAPIInitialize" );
lpfnMAPIUninitialize = (LPMAPIUNINITIALIZE)GetProcAddress( hMapiModule, "MAPIUninitialize" );
lpfnMAPILogonEx = (LPMAPILOGONEX)GetProcAddress( hMapiModule, "MAPILogonEx" );
lpfnMAPISendDocuments = (LPMAPISENDDOCUMENTS)GetProcAddress( hMapiModule, "MAPISendDocuments" );
lpfnMAPISendMail = (LPMAPISENDMAIL)GetProcAddress( hMapiModule, "MAPISendMail" );
if ( lpfnMAPIInitialize && lpfnMAPIUninitialize && lpfnMAPILogonEx && lpfnMAPISendDocuments )
{
HRESULT hr = (*lpfnMAPIInitialize)( NULL );
if ( SUCCEEDED( hr ) )
{
hr = (*lpfnMAPILogonEx)( 0, NULL, NULL, MAPI_EXTENDED | MAPI_USE_DEFAULT, &lplhSession );
if ( SUCCEEDED( hr ) )
{
// this opens the email client
// create the msg. We need to add recipients AND subject AND the dmp file
// file attachment
MapiFileDesc filedesc;
::ZeroMemory(&filedesc, sizeof(filedesc));
filedesc.nPosition = (ULONG)-1;
filedesc.lpszPathName = "E:\\Development\\Open\\testmail\\testmail.cpp";
// recipient(s)
MapiRecipDesc recip;
::ZeroMemory(&recip, sizeof(recip));
recip.lpszName = "QA email";
recip.lpszAddress = "[email protected]";
// the message
MapiMessage msg;
::ZeroMemory(&msg, sizeof(msg));
msg.lpszSubject = "Test";
msg.nRecipCount = 1; // if I comment out this line it works fine...
msg.lpRecips = &recip;
msg.nFileCount = 1;
msg.lpFiles = &filedesc;
hr = (*lpfnMAPISendMail)(0, NULL, &msg, MAPI_LOGON_UI|MAPI_DIALOG, 0);
if ( SUCCEEDED( hr ) )
{
hr = lplhSession->Logoff( 0, 0, 0 );
hr = lplhSession->Release();
lplhSession = NULL;
}
}
}
(*lpfnMAPIUninitialize)();
}
FreeLibrary( hMapiModule );
}
return 0;
}
This question is similar, but does not show how to add a recipient.
How do I do both?
We'd like the widest support possible for as many Windows platforms as possible (from XP and greater)
We're using visual studio 2008
Essentially we want to send an email with:
- pre-filled destination address
- file attachment
- subject line
from our program and give the user the ability to add any information or cancel it.
EDIT
I am trying to use MAPISendMail()
I copied much of the code from the questions linked near the top, but I get no email dlg box and the error return I get from the call is: 0x000f - "The system cannot find the drive specified"
If I comment out the lines to set the recipient, it works fine (of course then I have no recipient pre-filled in)
Here is the code:
#include <tchar.h>
#include <windows.h>
#include <mapi.h>
#include <mapix.h>
int _tmain( int argc, wchar_t *argv[] )
{
HMODULE hMapiModule = LoadLibrary( _T( "mapi32.dll" ) );
if ( hMapiModule != NULL )
{
LPMAPIINITIALIZE lpfnMAPIInitialize = NULL;
LPMAPIUNINITIALIZE lpfnMAPIUninitialize = NULL;
LPMAPILOGONEX lpfnMAPILogonEx = NULL;
LPMAPISENDDOCUMENTS lpfnMAPISendDocuments = NULL;
LPMAPISESSION lplhSession = NULL;
LPMAPISENDMAIL lpfnMAPISendMail = NULL;
lpfnMAPIInitialize = (LPMAPIINITIALIZE)GetProcAddress( hMapiModule, "MAPIInitialize" );
lpfnMAPIUninitialize = (LPMAPIUNINITIALIZE)GetProcAddress( hMapiModule, "MAPIUninitialize" );
lpfnMAPILogonEx = (LPMAPILOGONEX)GetProcAddress( hMapiModule, "MAPILogonEx" );
lpfnMAPISendDocuments = (LPMAPISENDDOCUMENTS)GetProcAddress( hMapiModule, "MAPISendDocuments" );
lpfnMAPISendMail = (LPMAPISENDMAIL)GetProcAddress( hMapiModule, "MAPISendMail" );
if ( lpfnMAPIInitialize && lpfnMAPIUninitialize && lpfnMAPILogonEx && lpfnMAPISendDocuments )
{
HRESULT hr = (*lpfnMAPIInitialize)( NULL );
if ( SUCCEEDED( hr ) )
{
hr = (*lpfnMAPILogonEx)( 0, NULL, NULL, MAPI_EXTENDED | MAPI_USE_DEFAULT, &lplhSession );
if ( SUCCEEDED( hr ) )
{
// this opens the email client
// create the msg. We need to add recipients AND subject AND the dmp file
// file attachment
MapiFileDesc filedesc;
::ZeroMemory(&filedesc, sizeof(filedesc));
filedesc.nPosition = (ULONG)-1;
filedesc.lpszPathName = "E:\\Development\\Open\\testmail\\testmail.cpp";
// recipient(s)
MapiRecipDesc recip;
::ZeroMemory(&recip, sizeof(recip));
recip.lpszName = "QA email";
recip.lpszAddress = "[email protected]";
// the message
MapiMessage msg;
::ZeroMemory(&msg, sizeof(msg));
msg.lpszSubject = "Test";
msg.nRecipCount = 1; // if I comment out this line it works fine...
msg.lpRecips = &recip;
msg.nFileCount = 1;
msg.lpFiles = &filedesc;
hr = (*lpfnMAPISendMail)(0, NULL, &msg, MAPI_LOGON_UI|MAPI_DIALOG, 0);
if ( SUCCEEDED( hr ) )
{
hr = lplhSession->Logoff( 0, 0, 0 );
hr = lplhSession->Release();
lplhSession = NULL;
}
}
}
(*lpfnMAPIUninitialize)();
}
FreeLibrary( hMapiModule );
}
return 0;
}

设置为“工作正常”。
哎呀 - 我忘了现在
Oops - I forgot to set
Works great now.
