Hi,

ive got an application which needs to send a HTML email with some embedded images in it.

Ive so far got the ability to send a plain text file with the .html file as an attachment, but thats no good for what i need.

Does anyone have any help or advice for getting HTML messages to work?

Here is my current code:

<br />
	MapiRecipDesc DefaultRecipient =<br />
	{<br />
		0,														                                				// Reserved<br />
		MAPI_TO,											                                				// Recipient class, MAPI_ORIG, MAPI_TO, MAPI_CC, MAPI_BCC<br />
		"Mark Ingram",										                                		// Name<br />
		"SMTP:me@me.com",		                                	// Address<br />
		0,																		                                // Size of entry identifier<br />
		NULL															                                		// Entry identifier structure<br />
	};<br />
<br />
  MapiFileDesc AttachedFiles = <br />
  {<br />
    0,                                                                    // Reserved<br />
    0,                                                                    // File flags, MAPI_OLE, MAPI_OLE_STATIC<br />
    0,                                                                    // Position to place file in message body<br />
    szTempFileName,                                                       // Fully qualified path of file<br />

  };<br />
<br />
	MapiMessage MailMessage =<br />
	{<br />

    0,                                                                    // Number of recipients<br />
    NULL,                                                                 // Recipients structure<br />

I seem to remember the body of the message needing to have <!DOCTYPE HTML PUBLIC"-//IETF//DTD HTML//EN"> at the beginning.

No that hasnt helped unfortunately Frown | :(

I used the code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML><HEAD><TITLE></TITLE><META http-equiv=Content-Type content="text/html; charset=iso-8859-1"><BODY><P><FONT size=2>test</FONT></P></BODY></HTML>

As the message body, but it just displays that exactly as it is (if you look at the format options the format is set to plain text and not HTML).

Are you sure that the e-mail client is not doing this? Some clients can only receive text messages, and any HTML that is received gets converted to text or outright removed.

Also, have you read the MSDN article Q268440?

I use PJ Naughter's excellent CSMTPConnection[^] class for HTML email.

unfortunately we cant use any MFC. But thanks for the link.
Its gotta be a c/c++ implementation.

I fail to understand the logic behind "can't use any MFC". Why make yourself jump through all sorts of hoops to reinvent the wheel.

As for the CSMTPConnection class, all it uses are CString, CArray, and CStringArray. It should not be to difficult to go through the code and replace them with the string and array classes that fit your requirements.

Because the project at work was started about 5 years ago by the MD of the project in standard C, therefore must use standard C.
And anyway, even if i didnt, i still prefer standard API calls, MFC is so bloated, yeah you can get small apps up and running really fast but when the project starts to grow it gets extremely difficult to stay in control of it all.
(Anyway, we should leave this as it isnt an MFC vs API thread :p)

Thanks, ill go through it and try to convert it,

passing by reference in c

Hmm, it appears that class actually sends the email itself via sockets etc. I was after a MAPI based solution that would open the default mail client's "New Message" window with the pre-written email. It would then be upto the mail client to send the message.

Cheers anyway tho.

Hello
I've got a file with reserved words and i want to load them to the heap memory. The problem is that i want to be able to work with the char **reservwords after loading it in the function loadreswords, i mean i want to see it in main.
The following code works for c++, as i pass it by reference (char **& reservwords in function header). But i need an ANSI C way of solving the problem.
Somebody said that i could use a char *reservwords[], but when i declare it the compiler says that the size is unknown, as i don't put anything between the [] as i want specify it's size after counting the number of words, and in c you must declare variables at the beginning of funtions.. thanks for helping!

<br />
<br />
void main (void)<br />
{<br />
    char  **reservwords;<br />
    loadreswords (reservwords);<br />
}<br />
<br />
void loadreswords (char **& reservwords)<br />
{<br />
    //opens a file with the reserved words, count them<br />
<br />
    palres = (char**) malloc ((sizeof(char*))*(*count_of_words));<br />
<br />
    //then for j=0  to count_of_words i allocate memory for each<br />
    //word that i read from the file, then copy the word in palres[j].<br />
<br />
    palres[j] = (char*) malloc (strlen(word)+1);<br />
}<br />
<br />

I dont quite understand your thinking behind your structure there, but surely the *& at the end cancel each other out. Therefore youre just expecting a char*??

Anyway, try using a double pointer in the function:
(Note also, main should be declared as int main in c/c++)

<br />
int main()<br />
{<br />
char* pointer;<br />
dofunc(&pointer);<br />
<br />
free(pointer);<br />
return 0;<br />
}<br />
<br />
void dofunc(char** dblpointer)<br />
{<br />
// you now have exact access to "pointer" in main() by using *dblpointer<br />
*dblpointer = (char *)malloc(strlen(text) + 1);<br />
}<br />

Hope that helps ya

what i am expecting from the file is a list of words. Part of the file:

auto
asm
break
case
char
const
continue
default
.
(continues)
.
void
volatile
while
(eof)

with :

<br />
void dofunc(char** dblpointer)<br />
{<br />
// you now have exact access to "pointer" in main() by using *dblpointer<br />
*dblpointer = (char *)malloc(strlen(text) + 1);<br />
}<br />

i think you are loading one word and i need to load a list of words.

Do you really have to use C? This seems like an obvious application for something like std::set<std::string> to me.

Anyway.

void LoadReservedWords ( char *** pppc )
{
    int i ;
    int count = CountReservedWords () ;
    char ** ppc  ;

    ppc = (char **) malloc (( count + 1 ) * sizeof ( char * )) ;

    for ( i = 0; i < count; ++i )
    {
        ppc [ i ] = ( char * ) malloc ( sizeof ( char ) * ReservedWordSize ( i ));
        strcpy ( ppc [ i ], ReservedWord ( i )) ;
    }
    ppc [ i ] = (char *) malloc ( sizeof ( char )) ;
    *ppc [ i ] = '\0' ;

    *pppc = ppc ;
}

void FreeReservedWords ( char ** ppc )
{
    char ** ppc2 = ppc ;

    while ( **ppc2 )
    {
        free ( *ppc2 ) ;
        ++ppc2 ;
    }
    free ( *ppc2 ) ;
    free ( ppc ) ;
}

int main(int argc, char * argv[])
{
    char ** ppc ;
    int n ;
    LoadReservedWords ( &ppc ) ;

    for ( n = 0; *ppc [ n ]; ++n )
    {
        printf ( "%s\n", ppc [ n ]) ;
    }

    FreeReservedWords ( ppc ) ;

    return 0 ;
}

I've obviously glossed the counting and accessing of your reserved words. Space is made for an empty string on the end of the array to use as a sentinel.
