如何使用C ++ Builder获取电子邮件正文

Question

I want to get the email body from my Gmail account for an email so i use this code i found it in an example for how to read emails using c++ builder pop3 the code to extract body used

TIdText *EText;
int message = SpinEdit1->Value;
MyPoP3->Retrieve(message, MyEmail);
Edit1->Text = MyEmail->Subject + " | " + MyEmail->From->Address;
Memo1->Clear();

for (int i = 0; i < MyEmail->MessageParts->Count; i++) {
    Memo1->Lines->Add(MyEmail->MessageParts->Items[i]->ContentType);
    EText = dynamic_cast<TIdText*>(MyEmail->MessageParts->Items[i]);
    Memo1->Lines->Add(EText->Body);
}

the problem is that i got undefine symbol to TidText and what i tried is to change it from TIdText to TIdMessage , but i got that i can't convert to it. also i tried to try this without loop or something MyEmail->Body->Text this return empty string.
the video i got this code from it here i don't know maybe the c++ builder he use is old. now i want to know how to extract the body text from the email address.
Thanks in advance.

the problem is that i got undefine symbol to TidText

Your code is missing an #include <IdText.hpp> statement.

what i tried is to change it from TIdText to TIdMessage , but i got that i can't convert to it.

Because TIdMessage does not contain nested TIdMessage objects.

also i tried to try this without loop or something MyEmail->Body->Text this return empty string.

If your email is MIME encoded, its text is not stored in the TIdMessage::Body property, but in a nested TIdText object within the TIdMessage::MessageParts collection. You have to look at the TIdMessage::ContentType property to know what kind of structure the email contains. For instance, if the CT begins with text/ , the text is in the TIdMessage::Body . But if the CT begins with multipart/ , the text is somewhere in the TIdMessage::MessageParts instead.

You should read this blog article on Indy's website for an example of how emails might be structured:

HTML Messages

the video i got this code from it here i don't know maybe the c++ builder he use is old.

No, it is not.
