Follow these steps for a simple example: 1. Create an internal 16 bit text tag called TagPassword. 2. Create an I/O field (data format string) and add above tag in Output Value attribute. 3. Create a button and add following C script on Operator-Control Enable attribute: ============================================================= #include "apdefap.h" BOOL _main(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName) {if (strcmp ( GetTagChar("TagPassword"),"abcd") == 0)//Return-Type: WORD { return 1; } else { return 0; } } ============================================================= So when password string "abcd" is entered in the field the button will get enabled, else grayed out. I have attached the example PDL WinCC version 6.2. The C course attachment in following thread is a good place to start: C-action in graphics designer Regards AttachmentNewPdl1.zip (678 Downloads) |
