Winhttpsendrequest 12175
web app, given a zip code it returns the city and state. Tested the web service, it error_winhttp_secure_failure works fine. I created a services collection in the script manager and pointed to my web service. I call the web service from an error_winhttp_incorrect_handle_state html input button click, per MS examples. I get a 12030 error. Now it seems the web service must be in the same domain as the web app, while this is a severe limitation I figured this was the problem. So https://msdn.microsoft.com/en-us/library/windows/desktop/aa383770(v=vs.85).aspx I created the web service on my localhost, I get the same error. I played around with page methods but kept getting object not defined errors so I gave up on that. (It seems the web method must be declared in the aspx file, but I still get this error.) Considering that the same domain limitation was enough to make the whole effort pointless (the web service will NOT be in the same domain as the web app) I thought I https://bytes.com/topic/asp-net/answers/683921-ajax-webserivces-error-12030-a would go the traditional route and use xmlhttprequest. I've used It before in asp.net 1.1 and it worked well. So I copy my working code from a 1.1 app, change the url to point to my Web service, invoke it and get access denied. Why access denied? No doubt it's MS protecting me from myself again. Here's the code: I'm using ?wsdl just to get some xml back for testing. function Button1_onclick() { debugger; var url = 'http://localhost/webServices/ZipCode/ZipCodeService.asmx? wsdl'; // branch for native XMLHttpRequest object if (window.XMLHttpRequest) { req = new XMLHttpRequest(); req.onreadystatechange = onComplete; req.open("POST", url, true); req.send(null); // branch for IE/Windows ActiveX version } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); if (req) { req.onreadystatechange = onComplete; req.open("POST", url, true); req.send(); } } } function onComplete(arg,usercontent) { debugger; if (req.readyState == 4) { if (req.status == 200) { // ...processing statements go here... } else { window.status="There was a problem retrieving the XML data:" + req.statusText; } } } Alternately I would love to use ASP.AJAX features to do this the 'right' way, but that 12030 error occurs no matter what I try. I'm sure I could get an update panel to work, but that requires a postback and processing of the page, even though the user's page is not refreshed- that seems to defeat the purpose of doing AJAX in the first place. kpg Jul 26 '07 #1 Post Reply Share this Question 2 Replies P: n/a George Ter-Saa

I also found while searching around that it might occur with IE 6. Are you making use of that browser by any chance? Check the logs of your IIS to see if something goes wrong and also the F12 developer tools > network tab to see what's going on. Grz, Kris.
