First of all, apologize in advance for my poor English, I'm a Chinese.
I'm testing an HTTP program, which will simply send some data to the server and get a respond. see attachment for the program. see this link for testing: http://www.easy-creator.net/test2/test.asp this program always fail, or just in my computer? I'm running win7-64bit, I've pre-set a debug break on where the error will occur and put a comment there and it wont get correct result, when WinHTTPAddRequestHeader was removed, this program will run, but wont get a correct result, when the web page is opened, it shows nothing, no posted data

Since your string is zero-terminated, you could just pass -1 and forget about dealing with lengths. oops, I just forgot the unicode/ascii problems... msdn told me that, just missed it .... but why my program can't post data to the server? first of all, I used ascii: "test=1111232...", and when I interrupted the send package, I did see that it was send to the server, why I can't see a result? |

I believe you mean the Content-Type header? The web server needs it to know what are you sending to it (remember that POST is also used to send files for instance). When you use "application/x-www-form-urlencoded" the ASP engine knows that it must set up the Request.Form array with the data you supplied (or whatever means ASP provides to read form data, I don't know ASP much)
