The problem is here again~ There will be footers and headers~and horizontal and vertical ones~ What should I do? The best thing is to use print preview~ Because it has settings At this time, you must reference a control of IE "WebBrowser" Quote in the page:
WebBrowser.ExecWB(1,1) Open WebBrowser.ExecWB(2,1) Close now All IE windows and open a new window WebBrowser.ExecWB(4,1) Save web page WebBrowser.ExecWB(6,1) Print WebBrowser.ExecWB(7,1) Print preview WebBrowser.ExecWB(8,1) Print page settings WebBrowser.ExecWB(10,1) View page properties WebBrowser.ExecWB(15,1) It seems to be revoked and needs to be confirmed WebBrowser.ExecWB( 17,1) Select all WebBrowser.ExecWB(22,1) Refresh WebBrowser.ExecWB(45,1) Close the form silently
Example: < object id="WebBrowser" width="0" height="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"> Print test
Copy and paste any text file~change the suffix name~ ie run~click preview~set printing~print~OK Then test it into the project~ For example, in aspx Run the same, click preview~ Hey~ Why does the IE security warning appear "Internet Explorer" has blocked this site from using ActiveX controls in an unsafe way" At this time, you need to change the security settings of IE (if you haven’t installed the patch, it will be fine ~ that’s because your “rp” is good, not necessarily the “rp” of customers and other people is as good as yours) Operation: Main menu "Tools" - Internet Options - Security - Custom Level, change "Initialize and script run ActiveX controls not marked as safe" in "Security Settings" from "Disabled" to "Enabled" Another method, "Tools" "Internet Options" "Trusted Sites (Trusted Sites)" "Site", then fill in the URL. If the website is not connected with https:, put the following " All sites in this area require server verification (https:). Just uncheck the box in front of it. (If it is a LAN: "Tools" "Internet Options" "Local Internet" "Advanced") (The wireless network does not seem to be a LAN) Recommend the second option~ Everything is ready ~ok~ Print method set (not tested one by one):
