Login dialog box did not come

hii

The same code used but the login dialog box did not come. it shows northerly.

After using "User Administrator" to create some user accounts, I followed these step and everything is ok:

Operation during runtime

Introduction

The following steps are necessary for a user to log in during runtime:

1. Start the runtime system.

2. Now open the password dialog using the shortcut keys for "Login" defined in the WinCC Explorer (Project Properties - Hotkey tab).

3. Enter your login name and the password in the dialog.

The system checks the authorizations you have been assigned with those of the editors and the installed components. If the authorizations match, the system unlocks the editors and components so that they can be used.

Now I want to call this login dialog by click on a "Login" button, I use this code and compile:

• Action for login (e.g. "mouse-click" event):
  #pragma code ("useadmin.dll")
  #include "PWRT_api.h"
  #pragma code()
  PWRTLogin('c');
• Action for logout (e.g. "mouse-click" event):
  #pragma code ("useadmin.dll")
  #include "PWRT_api.h"
  #pragma code()
  PWRTLogout();
  

And this code:
#pragma code ("useadmin.dll")
#include "PWRT_api.h"
#pragma code()
PWRTSilentLogin ("LogIn","Password");
But nothing happens when I click on "Login" button.

Please help me!

Hi gowsh,

With the function PWRTSilentLogin you make an automatically login. No login Dialog is shown

To show the login doalog you have to use the function PWRTLogin()
