With judgment, but he server control button, once every click will produce a new Ispostback, can request to the server at a time, then later image captcha aspx file isn't the result will refresh again, HTML server controls is also so, code to invoke the background with onserverclick events,

CodePudding user response:

?? Don't know what is your verification code, general captcha image point can't see you refresh and then refresh, verification code is point to determine the results of the judgment, only when you are to want what effect, if others can't lost after verification code for the refresh for other authentication code?
