I wanna use UrlDownloadToFileA in my patch. After I patch the the code and restart the PE, the <call UrlDownloadToFileA> always changes to <call some wired address>. I compared the patch and the source call function, they are different as that in the pictures: call <JMP.&URLDownloadToFileA> (source) call <urlmon.URLDownloadToFileA> (patch) How to make the patch instruction same as the source?

Hello guys. the command `bphws $abc, 'r'` puts a hardware breakpoint on execute. But, what i want to do via command is to `breakpoint > on acces > dword`. You know you can do this right click on **DUMP** window and select `breakpoint > on access > dword`. I have searched: Google x64dbg documentation tuts4you forums Unfortunately i couldn't find a way to do that. Did i miss something? P.S I need this because i am writing a script. Thank you :)
