Hi, I assume you can send MMS oK with the NowSMS web interface form, correct? The MMSCDEBUG.LOG looks like an HTTP GET request is being received instead of HTTP POST. Try adding DebugFull=Yes to the [MMSC] section of MMSC.INI and it should display a full hex dump of the HTTP request received. Have you tried the code here: http://www.nowsms.com/doc/submitting-mms-messages/send-mms-message-with-c-net It can be tricky to do a multipart/form-data upload ... that example is a few years old ... at the time we looked at it, we had to use a 3rd party library to format the multipart POST. -- Des NowSMS Support | ||||

hi Des, Yes you are right I can send MMS with the web interface. I enabled the DebugFull and the log looks like
I also tried the same method with the httpUploadHelper, but it does not work...here is my code: " try { HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://semcw16113/8800"); //"http://semcw16113/9000" req.ContentType = "multipart/form-data; boundary=---------------------------7de3b31e1a0752"; req.Method = "POST"; using (Stream s = req.GetRequestStream()) { s.Write(sendImage, 0, sendImage.Length); } string respStr; HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); using (Stream s = resp.GetResponseStream()) using (StreamReader sr = new StreamReader(s)) { respStr = sr.ReadToEnd(); } } catch (WebException wex) { StreamReader reader = new StreamReader(wex.Response.GetResponseStream()); string result = reader.ReadToEnd(); } " I read this post "http://support.nowsms.com/discus/messages/485/6557.html", seems i should use port 8800. - If I try 8800, no exception happened but device can not receive mms; - If I try 9000, there is something shown in the MMSCDEBUG.LOG, and i got "Unknown request: content type is unknown" error...fail again. Please help me out... Qingjun | ||||

Hi Qingjun, There appear to be multiple issues. The first (and most critical) is that HTTP_CONTENT_TYPE should be Content-Type Another problem is the variable names for the data elements. In the debug log I see variables like this: name="ctl00$ContentPlaceHolder1$MMSText" But it should be: name="MMSText" -- Des NowSMS Support | ||||
