Send email with CDO 2000

Submitted by Sergey on May 1, 2008 - 10:18

It's simple and convenient to send unattended email with CDO 2000 as long as there's a SMTP server available.


Note 1 Uses CDO 2000 class for sending emails

This is sample code. Add error handling and adjust to your requirements as necessary.

* Replace addresses with real ones before running the code
 
loMail = NEWOBJECT("Cdo2000", "Cdo2000.fxp")
 
WITH loMail
	.cServer = "smtp.somedomain.com"
 
	* Uncomment following lines and fill your credentials 
	*	if your SMTP server requires basic authentication
	*.nAuthenticate = 1 	&& cdoBasic
	*.cUserName = "myusername"
	*.cPassword = "mypassword"
 
	.cFrom = "somemailbox@somedomain.com"
	.cTo = "somebody@otherdomain.com, somebodyelse@otherdomain.com"
 
	.cSubject = "CDO 2000 email"
 
	* Uncomment next lines to send HTML body
	*.cHtmlBody = "<html><body><b>This is an HTML body<br>" + ;
	*		"It'll be displayed by most email clients</b></body></html>" 	
 
	.cTextBody = "This is a text body." + CHR(13) + CHR(10) + ;
			"It'll be displayed if HTML body is not present or by text only email clients"
 
	* Attachments are optional
	* .cAttachment = "myreport.pdf, myspreadsheet.xls"
ENDWITH
 
IF loMail.Send() > 0
	FOR i=1 TO loMail.GetErrorCount()
		? i, loMail.Geterror(i)
	ENDFOR
	* Clear errors
	loMail.ClearErrors()
ELSE
	? "Email sent."
ENDIF

CDO2000 cHTMLBodyURL file access denied after 1st Use

Submitted by Bill Mast (not verified) on November 18, 2009 - 15:31.

Hi, Sergey,

Thanks so much for the example CDO200 stuff you have posted.

I have one problem. Using the cHtmlBodyURL property, I can successfully place the contents of an HTML file I created in Visual Foxpro code into the body of the sent message. However, this only works the first time through (in a Visual Fox session). If I try to run it again, I get "file access denied" when trying to re-create my HTML file by using SET ALTERNATE TO. It seems CDO2000 is keeping a lock on the file. If I quit Fox, and come back in and run the program, it works fine.

I have tried all sorts of RELEASE and CLOSE commands in the program, but nothing works.

Any ideas on what I'm missing?

Thanks,

Bill

Did you try to release CDO object?

CDO2000 File Access Problem Solved!

Submitted by Bill Mast (not verified) on November 21, 2009 - 12:30.

Sergey,

In another gem you wrote about using Gmail and CDO2000, I found TWO solutions to the problem.

In my program, I set "savefile" to a file name, then used SET ALTERNATE to write the HTML code to it (and closing it properly!). Then, either one of the following works, AND allows the creation of the file and SEND to be performed consecutive times without the dreaded "File Access denied".

1. .cHtmlBody = FILETOSTR(savefile) && this works! No mysterious file lock on savefile afterwards

2. .cHtmlBodyUrl = "file://" + FULLPATH(savefile) && this also works, no mysterious file lock on savefile afterwards

For some reason, using just the file name (savefile) in the cHTMLBodyURL causes the weird lock on savefile afterwards.

Thanks for all your help, Sergey.

Problem with Chinese characters

Hi Sergey,

Thanks for your code. It works well for English contents but Chinese characters will become garbage. Is there any way to fix the problem?

Thanks,
Ben Tam

Changes to use additional authentication

What changes do I need if they require additional authentication and it is different than their normal login and password?

Thanks.

Hi Don,

The CDO 2000 supports only following three types of authentication:

  • cdoAnonymous, value 0. Do not authenticate.
  • cdoBasic, value 1. Use basic clear-text authentication. When using this option you have to provide the user name and password through the sendusername and sendpassword fields.
  • cdoNTLM, value 2. The current process security context is used to authenticate with the service.

Sending a Batch of eMails with one call to Send()

Hi Sergey

Is it possible to create a number of email messages to different people with different attachments etc. and then just call the Send() method once to send all the messages?

Thanks,
Simon

Hi Simon,

You'll have to call Send() once per each email. There's no batch mode.
