Hello, my Problem is that i like to set the Port from a Editfield and i dont know whats wrong with my routine. i think it must work ,but all i get is : cant connect if i write only this : push port call htons; mov,ax all works fine ,but this takes the Port i wrote in database. i like to use the port from an editfield. so i try this: push offset Port push 16 push WM_Gettext push_IDE_PORTFIELD <--- the editfield push HWND call senddialogmessagea push offset Port call htons mov,ax in database i change : Port dd 1234 to Port db 16 dup(0) but i cant connect and dont know whats wrong. i use asm since 4 weeks and i dont want to give up. when i use try and error for this ,i get mosttime a blue screen and need to restart the system. so its frustrating. i use the SAME function to get the IP and it works ,so i dont understand whats wrong. Thanks for help cu

First case is equal to: push 1234 ;in decimal call htons Second case is equal to: push (address of first byte of "Port") call htons I assume this isn't what you meant to do! You probably meant to convert the text in "Port" to a DWORD! There are several functions provided in the MASM32 lib, see a2dw etc. So your code should be more like: (I use invoke) invoke SendDialogMessageA, HWND, IDE_PORTFIELD, WM_Gettext, 16, offset Port invoke a2dw offset Port ;Probably wrong proto, but no docs with me! invoke htons, eax ;Use result of a2dw as htons argument! mov,ax Not sure if I explained it that well, or if it solves your problem, but I think its the answer!
