小弟对c语言全局动作不是太了解，请各位高手帮助看下，调试半天了老是在下边那行报错，工程是这样我已经在wincc里边建好了用户密码，



int gscAction( void )
{
#pragma option(mbcs)

#pragma code ("UseAdmin.DLL")
#include "pwrt_api.h"
#pragma code ()

char szUserName[255];
int szPassword;

strncpy(szUserName,GetTagChar("@CurrentUserName") , 250); //Return-Type:

szUserName[250] = '\0';
szPassword=123456; //Return-Type: char*

if (PWRTSilentLogin(szUserName,szPassword) == FALSE) // 就在这行报错 type mismatch in argument 2

{
OpenPicture("main.Pdl"); //Return-Type: void
#define PIC_1 "login.Pdl"
CloseWindow(PIC_1);
}

SetTagBit("tiggerc",0); //Return-Type: BOOL

return 0;
}
