如何以与我在Windows资源管理器中“发送到邮件收件人”相同的方式以编程方式发送电子邮件？

ShellExecute() allows me to perform simple shell tasks, allowing the system to take care of opening or printing files. I want to take a similar approach to sending an email attachment programmatically.

ShellExecute()允许我执行简单的shell任务,允许系统负责打开或打印文件。我想采用类似的方法以编程方式发送电子邮件附件。

I don't want to manipulate Outlook directly, since I don't want to assume which email client the user uses by default. I don't want to send the email directly, as I want the user to have the opportunity to write the email body using their preferred client. Thus, I really want to accomplish exactly what Windows Explorer does when I right click a file and select Send To -> Mail Recipient.

我不想直接操作Outlook,因为我不想假设用户默认使用哪个电子邮件客户端。我不想直接发送电子邮件,因为我希望用户有机会使用他们的首选客户端编写电子邮件正文。因此,当我右键单击文件并选择Send To - > Mail Recipient时,我真的想要完全实现Windows资源管理器的功能。

I'm looking for a C++ solution.

This is my MAPI solution:

这是我的MAPI解决方案:

#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;

        lpfnMAPIInitialize = (LPMAPIINITIALIZE)GetProcAddress( hMapiModule, "MAPIInitialize" );
        lpfnMAPIUninitialize = (LPMAPIUNINITIALIZE)GetProcAddress( hMapiModule, "MAPIUninitialize" );
        lpfnMAPILogonEx = (LPMAPILOGONEX)GetProcAddress( hMapiModule, "MAPILogonEx" );
        lpfnMAPISendDocuments = (LPMAPISENDDOCUMENTS)GetProcAddress( hMapiModule, "MAPISendDocuments" );

        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 with "C:\attachment.txt" as an attachment
                    hr = (*lpfnMAPISendDocuments)( 0, ";", "C:\\attachment.txt", NULL, NULL );

                    if ( SUCCEEDED( hr ) )
                    {
                        hr = lplhSession->Logoff( 0, 0, 0 );
                        hr = lplhSession->Release();
                        lplhSession = NULL;
                    }
                }
            }

            (*lpfnMAPIUninitialize)();
        }

        FreeLibrary( hMapiModule );
    }

    return 0;
}

You can use a standard "mailto:" command in windows shell. It will run the default mail client.

您可以在Windows shell中使用标准的“mailto:”命令。它将运行默认邮件客户端。

#3

The following C++ example shows how to invoke the SendTo mail shortcut used by Windows Explorer:

#4

You'll need to implement a MAPI client. This will let you prefill the document, add attachments, etc.. before presenting the message to the user to send off. You can use the default message store to use their default mail client.

您需要实现MAPI客户端。这将允许您在向用户发送消息之前预填充文档,添加附件等。您可以使用默认邮件存储来使用其默认邮件客户端。
