open user archive by name on WinCC client

Hi.
as i read the user archive application starts only on winccserver.
it is known way to switch on in startup on the client the application. but there are no possibilties to do it because of it grey color of checkbox (deactivated by system).

#include "apdefap.h"
void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)

{
UAHCONNECThConnect;
UAHARCHIVEhArchive;

char* date;
char filter[80]="",temp[10]="";
BOOL ack;
SYSTEMTIME st;

if ( uaConnect ( &hConnect ) == FALSE)
{
printf("Error calling uaConnect: %d \n", uaGetLastError() );
return;
}

if (hConnect==NULL)
{
printf ("Handle UACONNECT equals 0\n");
}

if ( uaQueryArchiveByName ( hConnect,
"Incoming",
&hArchive) == FALSE)
{
printf("Error calling uaQueryArchiveByName: %d \n", uaGetLastError() ); \\this errorshowed on client
uaDisconnect ( hConnect );
return;
}

Hi
"..so you are using MultiClients??? Did you generate packages for your MultiClients and load them?"
yes, yes. the project could be started.
i receive the data to the online table, but couldn't open archivebyname with c-action listed above.
it gives us an error 101.

we supposed problem due to installation but WinCC installed properly. and change/remove of WinCC in Add/remove programm shows us that ua installed. so the question is the same as above

i can use the online table user archive control and can see contains of the user archive with table. but couldn't open archive throw the c-action.
it says that possible to use :: for addressing. does somebody knows what is the syntaxis for using?
